Review: 2011 Jaguar XKR Convertible

I know you’re probably here to read all about how the 2011 Jaguar XKR Convertible stacks up against other six-digit luxury sports cars, but I’ve got a confession to make. Before we get down, dirty and up to our elbows in power figures, you need to know that this is my first real brush with luxury performance of this caliber. As we speak, the ruling houses of auto journalism are likely sending laptop-wielding assassins my way for breaking the seventh sacred tenet of our craft – “Always pretend you know more than you do” – but I can’t accurately convey my time with this big cat without first giving you a taste of my perspective.

Get the mouthwash ready, this may be unpleasant.

My office is headquartered in a beautiful part of East Tennessee, where $30,000 will happily buy you seven acres of wooded hill country. Around here, I’m pleased to say that I’m more likely to hear a Massey-Ferguson lumber past my window than a Maserati, and as such, most folk have neither the use for a high-horsepower 2+2 convertible nor the ludicrous kind of coin it takes to call one your very own. As one neighbor remarked, “You can buy a damn nice home for as much as that thing costs.”

And for the majority of the country, he’s dead right.

Receiving word that you’ll be the sole custodian of a 2011 Jaguar XKR Convertible for a week and actually meeting the beast in the sultry flesh are two entirely different things. When the machine arrived, it announced its presence with a low rumble that snaked its way through the pine, gypsum and hardwood of the house and into my ears long before it showed its face in the driveway.

Intrigue, thy name is the 5.0-liter, supercharged V8 planted behind this kitty’s headlights.

I mark the third generation of my clan to call this particular house my own, and while there have been some true curiosities parked in this driveway over the past few decades, there’s never been anything quite like this topless supercharged wonder. Approaching the XKR Convertible from the rear, you’re met with the kind of knee-shaking aesthetics that few vehicles possess. Tall, rounded flanks work their way into a concise aft dominated by LED taillamps, a steep rear deck spoiler and four menacing exhaust outlets. Vast 275-series tires the size of a pair of small continents peek out from below the rear valance, and from this angle, there’s no mistaking this convertible’s true purpose.

Move down the sports car’s side and you’re introduced to a full 188.7 inches of sprawling bodywork. With a lengthy 108.3-inch wheelbase, Jaguar’s designers had plenty of space to ply their art. From the sides, prominent haunches define the XKR Convertible’s profile before transitioning easily into a low-slung nose that rolls on for a country mile. It’s the kind of look that could induce labor or stop your heart if you aren’t prepared for what you’re seeing.

Don’t be surprised if you leave a trail of newborns and cardiac arrest in your wake.

At least, that’s the case with the top down. Crank the soft shell up with a merry push of a convenient, windshield frame-mounted button and the spell’s handily broken. Jaguar has done an excellent job of incorporating a smooth top structure, but the mechanism draws undue attention to the massive proportions of the rear deck. While everything looks squared away with the car slinking around topless, you can’t help but think there’s enough sheetmetal out back to set up a regulation badminton court with the roof in place. Fortunately, the top stows in around 17 seconds, so you don’t need to waste any time should the sun start shining.

Jaguar was kind enough to supply the XKR Convertible with a set of heated and cooled ventilated leather seats up front that are fully capable of boiling up a cup of Earl Grey should you become stranded far from a kettle at tea time. With the seats set to incinerate and the heater dialed to blast furnace, mother nature was no match for this kitty’s open-air motoring.

In addition to being able to tan your hide, the front seats are also nearly infinitely adjustable. That includes bolsters that can be tweaked to squeeze you tighter than your one true love. That little trick joins the standard portfolio of fore/aft and up/down wizardry to serve up seating custom tailored for nearly every size and shape.

The rest of the cabin swaddles you in no less comfort. The leather dash is double-stitched with contrasting thread, and a lumber yard’s worth of polished burlwood accents adorn those surfaces that aren’t already covered in hide. It’s a beautiful place to spend an hour or three, so long as you don’t have to fight the touchscreen infotainment system. Commands to change the radio station are seemingly sent by first-class air mail to an overburdened worker in Coventry where they must be approved before taking effect. Don’t expect anything to happen quickly.

The thermometer bobbed at around 40 degrees my first night with the XKR Convertible, but with stars peeking through the bud-laden branches and no clouds in sight, there was no way in this life or the next that I was going to leave this cat in the driveway. I stowed the top and headed for the snaking asphalt of Union County. From the first press of the glowing start button, it was clear I had stumbled into an alternate universe of propulsion. This is no sewing machine, and at no point did I have to check to see if the engine was running.

Jaguar has made damn sure that you feel the supercharged 5.0-liter V8 come to life, and it does so with a bark that serves as a harbinger of all sorts of naughtiness. If the starting sequence is the gateway drug of Jaguar love, the first punch of the accelerator is straight methamphetamine. You can forget fighting this addiction. The automaker’s engineers have managed to wring a full 510 horsepower and 461 pound-feet of torque from the eight force-fed cylinders, and every dash to 60 miles per hour clicks off in a claimed stammer-inducing 4.6 seconds. That’s shorter than the time it took you to read that last sentence, which is an impressive feat given that the XKR Convertible tips the scales at a whisker under two tons.

The six-speed automatic gearbox is a work of art, dispatching upshifts with quicker-than-thou precision and serving up rev-matching downshifts with a click of a paddle. An extra cog or two would likely go a long way toward bettering the vehicle’s 15 miles per gallon city and 22 mpg highway EPA rating, but really, who’s counting?

In order to keep all that momentum-building glory in check, Jaguar has bolted on a traction control system that must have been programmed by a panel of ruler-wielding nuns. No matter how desperately you mash buttons or turn dials, get too happy with the accelerator and you’ll get your knuckles rapped in a hurry. Even with the gearbox set to Sport, Competition mode on and Dynamic Stability Control off, I was barely able to get a few decent revolutions of wheel-spinning heaven before being made to submit to she-who-rules-all-nannies. I don’t even want to talk about attempting to ply the throttle in anger with the parameters adjusted to more sane settings.

Still, the chaperone under the hood wasn’t enough to quell my lust for this car. Even with 3,968 pounds of heft to scoot along, the dynamic suspension is perfectly firm for a series of apexes while turning buttery supple to accommodate imperfections in the tarmac. Mix in a brake system fully capable of pulling your eyelids from your face and you’re delivered a grand tourer that can go 10 rounds with lighter sports cars all night long. The machine is just as happy to consume mile after mile of rolling highway as it is darting from one mountain corner to the next.

Pulling into the driveway after a full hour of sampling all the talents the XKR Convertible has to offer, I was convinced that Jaguar had managed to build a vehicle that was worth every copper cent of its MSRP.

That was the honeymoon.

With the sun shining after work the next day, I was looking forward to dinner out with the wife followed by a long ride home via some of the area’s more desolate roads. We hopped in, I hit the key and was instantly rewarded with a glowing check engine light. Having suffered through the hazing associated with English vehicle ownership in the past, a few dozen Lucas jokes buzzed through my brain before I could so much as mutter a curse.

For the uninitiated, Joseph Lucas founded the company behind nearly all of the electrical components under the hood of hardware from jolly old England. His gear had a reputation for reliability that was about as spotless as a pair of polka dot socks. There’s a reason they say the company holds the world’s only patent on the short circuit.

Still, check engine lights are nothing new or special, even on a vehicle with 2,200 miles on the clock. We piled back out and the next day I got the pleasure of spending some time with the experts at Harper Jaguar. The problem stemmed from a faulty evaporation system sensor, and in no time the techs at the dealer had the XKR Convertible up and running again. There was much rejoicing.

Or at least there was until two days later, when the light reared its head once again. Having precious few days before having to leave town, I wasn’t interested in carving out any more time to have the vehicle addressed. I parked the cat in the driveway and defaulted to the familial fleet for the remainder of my transportation needs.

Jaguar’s current owner, Tata, inherited an entire British brand that was on its way up. From beautifully-styled XF, XJ and XK models to vastly improved reliability records, Jaguar is heads and shoulders above its old self. In fact, the automaker routinely scores well in J.D. Power and Associates surveys. Unfortunately, those scores are based largely on the company’s previous generation hardware, not the new kit that mostly fills Jag showrooms now.

Granted, the poor vehicles submitted to the vicious hands of the average automotive journalist endure acts banned by the Geneva Convention, but by and large, most automakers manage to serve up products that can at least manage three days without needing attention from a qualified service professional.

I can’t help but imagine what would happen if Kia, Toyota or Chrysler began cranking out vehicles with the kind of reliability woes that recent Jaguar models have come to be known for. Whereas the big cat is more or less given a pass for its luxury pedigree and history of foible-ridden vehicles, other brands are held to continuous scrutiny.

Having been completely wowed by an excellent interior and heavenly drivetrain, I’m more than a little soured by my run-in with the ghost of Lucas’ past. Until Jaguar can get its reliability house in order, I have to imagine there are better places to spend your $103,375. A nice house on a few dozen acres in Tennessee, perhaps…

BMW announces three two-car teams for 2012 DTM series

http://www.sportscarsfans.com/images/script/image.php?id=D042_4D93750A

Touring car racing fans are eagerly anticipating the return of BMW to the DTM series. The Bavarian automaker last competed in DTM (or its progenitors, anyway) a whopping 18 years ago, but late last year announced it would return to the German touring car series in 2012. Now it has revealed the means to that end.

Rather than field its own entries, BMW will be supplying the vehicles and factory support for three independent teams: BMW Team RBM, BMW Team Schnitzer and Reinhold Motorsport GmbH. Both RBM and Schnitzer have a longstanding relationship with BMW Motorsport, while Reinhold is a completely new outfit. Each of the teams will be fielding two of the new M3 DTMs that are currently under development.

The move to DTM comes on the back of some big shakeups in BMW’s racing program. Although it pulled out of Formula One two years ago, and eliminated its works World Touring Car Championship effort at the end of last year, it has recently pitched the Mini division into the WRC with Prodrive and launched the DTM program to pick up where it left off in the WTCC.

PRESS RELEASE:

BMW Motorsport presents the teams for its DTM project.

BMW Motorsport heralds a new era on its way entering the DTM. Development of the car has been running at full speed in Munich for some months now, as has the central preparation for the logistics and assembly of the race cars. Three teams, each lining up with two BMW M3 DTM cars, will be responsible for the races themselves.

BMW Motorsport has enjoyed great success in production car racing in the past with both BMW Team RBM and BMW Team Schnitzer, and all those involved are hungry for more of the same. In Reinhold Motorsport GmbH they are joined by a new team still in its fledgling stage, but which boasts individual members with a vast wealth of motorsport experience.

Mario Theissen, BMW Motorsport Director, says: “In recent months we have worked very intensely on the DTM project. The agreement with the teams was of paramount importance. We were pleased with the high level of interest and numerous applications and presentations received from a number of professional teams. The concepts presented by BMW Team RBM, BMW Team Schnitzer and Reinhold Motorsport GmbH ultimately convinced us. This is an excellent team line-up for BMW. For us, it is important that all three teams have absolute equal rights. We are looking forward to cooperating over the coming years – and hope to enjoy great success together.”

Bart Mampaey, Team Manager of BMW Team RBM, says: “The DTM is one of the toughest and the most popular racing series in the world for production cars. From a sporting point of view this poses a great challenge – but an appetizing one. We are honoured to be able to continue our successful cooperation with BMW Motorsport, which has yielded many WTCC titles, in the DTM. We still have a lot of work ahead of us over the coming months, and are now looking forward to getting to grips with the project.”

Stefan Reinhold, founder of Reinhold Motorsport GmbH, says: “In April last year, BMW announced its intention to compete in the DTM. From this day on, we have always wanted to be a part of this project. Shortly after the announcement, we presented our concept to BMW in Munich, and started to work on meeting the prerequisites for any potential cooperation. We are very proud to have been given the nod. To be part of the BMW Motorsport family with immediate effect and to strive for DTM success together is simply fantastic. We can hardly wait to get started and to vindicate the huge amount of trust BMW has placed in us.”

Charly Lamm, Team Manager of BMW Team Schnitzer, adds: “We are really looking forward to tackling the DTM project together with BMW. Schnitzer Motorsport has enjoyed a successful past in the DTM and achieved many victories together with BMW. However, past success is no guarantee that we will also be victorious in the future. The bar is set really high in DTM, and our preparations will be intensive to meet this challenge. Every team is highly motivated and the anticipation is mounting every day as we get closer to the start of the 2012 DTM season.”

BMW Team Schnitzer will run two BMW M3 GT cars for BMW Motorsport at the major endurance races in Europe and Asia. BMW Team RBM is involved in BMW customer racing projects, including the development of the BMW 320 TC and the further development of the BMW Z4 GT3.

Mario Theissen says: “While the preparation for this year’s involvement on the endurance racing circuit with the BMW M3 GT is in its final phase, the DTM project has picked up pace over the past few months. In naming the teams, we have taken the next step. As well as developing the car, it is now a matter of assigning tasks and establishing structures and processes. The cooperation between BMW Motorsport and the teams, as well as that between the team bases and the race track, must be well established. Only then will we make a statement regarding the driving line-up.”

BMW Team RBM in profile.

In 2012, BMW Team RBM will compete in the DTM with three world championship titles to its name. Under the leadership of Team Manager Bart Mampaey, the team from Mechelen, Belgium, not only won the 2004 European Touring Car Championship with Andy Priaulx at the wheel, but also proved to be the team to beat in the World Championship…
BMW Team RBM in profile.

In 2005, 2006 and 2007 the celebrations after the final WTCC race in Macau all took place in front of the RBM garage. Bart Mampaey is now looking forward to the DTM. “Competing in the DTM will be a big challenge for our team,” he says. “We are delighted that BMW is putting its faith in us again. We will use the time leading up to the first race to prepare as well as possible. The whole team is extremely motivated and hungry to get on with the development work. It is fantastic to be on board right from the start when a manufacturer like BMW launches this kind of project. We have a lot of hard work ahead of us, as the standards in the DTM are extremely high.”

Efficiency is an important factor in daily work for BMW Team RBM. Mampaey is constantly striving to use time and resources efficiently, in order to extract the full potential of the car. The team profits from the infrastructure of the BMW dealership, which the Mampaey family manages under the name JUMA. Synergies and allows RBM to concentrate on the basics: the performance on the race track.

JUMA stands for Julian Mampaey. Today’s RBM boss inherited his love of motor sport from his father. The JUMA team made a name for itself in the 1970s and 1980s, claiming three overall victories for BMW at the Spa-Francorchamps 24-hour race. Nine years after the final JUMA race, Bart Mampaey stepped into his father’s footsteps in 1995. At first, RBM was responsible for the cars in the BMW Compact Cup in Belgium. Soon after that, the Mampaey family celebrated a successful comeback at Spa: the Group N one-two in the 1997 24-hour race was followed by overall victory with the BMW 318i one year later. This was also the last overall victory for BMW to date at the “Ardennes Rollercoaster”.

RBM sent a BMW 320i to the European Touring Car Championship for BMW Belgium for the first time in 2002. One year later the team appeared for the first time in the colours of BMW Great Britain, and Priaulx was signed up to drive. After a year gaining experience in 2003, RBM caused a sensation in 2004 when Priaulx claimed the ETCC title in Dubai. Three World Championship titles show categorically that this victory was not a flash in the pan for Mampaey and his crew.

“A change of scenery will do us good, particularly when we have the prospect of lining up in a successful series like the DTM,” Mampaey says. “Having won three World Championship titles, everyone in the team is looking forward to seeing how we fair against the other teams in the DTM.”

Back to the future.

Back to the future: this could be the motto of BMW Team Schnitzer for the 2012 DTM season. Charly Lamm’s team sported BMW colours in this series back in the 1980s and 1990s – and with great success. A Schnitzer driver crossed the finish line in first place in a BMW M3 on 17 occasions, and the team also claimed eight pole positions and set 18 fastest laps.

BMW Team Schnitzer’s greatest success in the DTM came in its very first season, when Roberto Ravaglia won the 1989 drivers’ title for the team from Freilassing. BMW Team Schnitzer will make its DTM comeback in 2012, almost 20 years after its last victory in Hockenheim on 11th October 1992.

“We lined up with the BMW M3 in the DTM for the first time in 1989, and were able to win the title with Roberto Ravaglia at the first attempt,” Lamm recalls. “The four seasons up to 1992 were a great time, with spectacular and thrilling races, which will always have a special place in the history of Schnitzer. Even back then, the DTM was extremely popular in Germany. It is now almost 20 years since our last DTM race. We are well aware that the series has changed dramatically. The level of competition is extremely high and the series has a far more international flavour to it. As a result, rookies like us face a huge challenge. However, we will approach the task in hand with great verve.”

During the break from the DTM, the Schnitzer team continued to line up for BMW, adding many new chapters to the brand’s motorsport success story. In 1999 it claimed overall victory at the legendary Le Mans 24 Hours (FR) with the BMW V12 LMR prototype. In 2001, BMW Team Schnitzer won the drivers’, team and manufacturers’ titles in the American Le Mans Series (ALMS) with the BMW M3 GTR.

The team also has a very special relationship with the legendary 24-hour race at the NĂĽrburgring-Nordschleife (DE). BMW Team Schnitzer finished as overall winner in the “Green Hell” in 1989, 1990, 2004, 2005 and 2010, making it one of the most successful teams in the history of this classic race. Schnitzer also enjoyed success after success in the European Touring Car Championship between 2002 and 2004, as well as the World Touring Car Championship between 2005 and 2009. The team’s drivers crossed the finish line as winners on 45 occasions in the European and World Championships.

In the last 50 years, Schnitzer has won 16 championships with BMW – including the 1987 World Touring Car Championship, three European Touring Car Championships, and championships in Germany, England, Italy, Japan and South East Asia.

Lamm adds: “We will attempt to readapt to the DTM as quickly as possible. We have great respect for the current manufacturers and teams in the DTM. They have set the bar very high. From now on we will be working on equalling, or even surpassing, the standards they have set as soon as possible.”

“Our greatest asset is definitely the people in our team”.

Stefan Reinhold’s team, which will line up at BMW’s DTM comeback in 2012, may be a newcomer to the series – but its members are by no means lacking experience. The team’s great strengths are its individual know-how and the precise way in which it uses each member’s skills.

“The crew comes from all areas of professional motor racing,” Reinhold explains. “From GT racing and the World Rally Championship, as well as DTM and Formula One. Almost all the team members have experience gained in several fields of motorsport. They are used to working at the highest level. Clear communication and the optimal use of experience and resources, as well as uncompromising commitment, are fundamental attributes of the team. Our greatest asset is definitely the people in our team.”

The team structure started with a blank sheet of paper. Reinhold took the time to analyse the individual strengths of his crew and used this as a basis to assemble his team step by step. By the start of 2012, 25 engineers and technicians will be involved in the DTM project.

Reinhold himself has Formula One and GT racing experience to his name and has been toying with the idea of launching his own racing team for a long time. When BMW announced its return to DTM this idea took shape and work began on the conception. “In late summer 2010 we started with the concrete planning and then applied to BMW with our concept in the autumn,” Reinhold recalls. “The fact that we won BMW Motorsport over with our concept is the perfect reward for the hard work we put in during this phase.”

The team has moved into headquarters in Niederzissen. The proximity to the NĂĽrburgring is not the only reason for motor racing being omnipresent on the team’s premises, as its former tenant was also a prominent name in motorsport: the Zakspeed team previously operated from this site and has now rented the facilities out to Reinhold.

Over the coming months, Reinhold and his team will work at full speed on the team structure in order to be ready for the first test drive with the BMW M3 DTM. “Everything from the washers to the semi-trailer will be new in our team,” says Reinhold. “However, I do not by any means see this as a disadvantage. We are very keen to take on the established DTM teams and, along with our partner BMW, to be competitive as soon as possible.

First Drive: 2012 Mercedes-Benz SLK-Class

We usually see women behind the wheel of the Mercedes-Benz SLK-Class. Who can blame them? It’s a cute little car. The original SLK debuted in 1996 with a four-cylinder powerplant and all of 136 ponies. What it lacked in the motivation department it made up for with its Vario-roof retractable hardtop. Not since the 1957 Ford Skyliner could a car stop so much traffic while parked.

The SLK gained some testosterone with its first facelift in 2000. While the exterior was still rather tame, the chick car jokes ceased in 2001 with the introduction of the 354-horsepower SLK 32 AMG.

Things continued to get better with the all-new 2004 edition and its sleeker styling that paid homage to Mercedes’ Formula One designs and the beastly McMerc SLR. The reality that AMG could stuff its hand-built 5.4-liter V8 under the hood made the second-generation SLK a serious performance car.

For 2012, the SLK officially begins its third generation, and you can see the difference from 100 yards. Especially from the front view, the roadster looks more mature and substantial. The split-grill design reconstitutes the 190 SL’s design from the late 1950s in a handsome, modern manner. The bolder aesthetics continue in the rear, which features large arches over the rear wheels and LED taillamps. And it keeps getting better on the inside…

Inside, the modernized retro theme continues, with our SLK350 tester’s circular vent outlets ported through the handsomely contoured dash covered in hand-stitched Nappa leather (like the SLS AMG). Round analog gauges flank a center digital display in the main binnacle, while a bright, seven-inch LCD handles navigation as well as manipulating the climate control and infotainment systems.

While the interior and exterior are mostly new, from an engineering standpoint, the third generation seems more like a Gen 2.5.5; a facelift of the 2008 facelift. The 2012 SLK rides on the same 95.7-inch wheelbase. It’s about an inch longer and an inch wider (overall width and track), and the tidy dimensions help this car stay true to what SLK stands for: Sportlich (sporty), Leicht (light) and Kompakt (compact).

Engines are familiar to fans of the Three-Pointed Star. In the States, we will eventually get two of three available engines for the new SLK: the 1.8-liter turbocharged four-cylinder and the naturally-aspirated 3.5-liter V6. Four-cylinder models will be called the SLK250, while V6 models gets the SLK350 badge. For 2012, both engines gain direct fuel injection in a nod to efficiency. Horsepower, torque and preliminary estimated miles per gallon figures are 201, 229 pound-feet, and 23/31 for the 1.8-liter engine and 302, 273 lb-ft., and 20/29 for the uprated V6. On this trip, only the six-cylinder SLK350 was available for us to drive, as it will be the only model offered when the SLK goes on sale in June. The SLK250 is scheduled for availability in the U.S. later in the model year.

Both engines run their torque through an updated seven-speed automatic modified to accommodate a new fuel-saving start/stop functionality. Unfortunately, cars coming to the USA won’t be getting the latter feature – at least for the moment. That’s too bad, given where fuel prices are trending and the system’s relative smoothness. Mercedes-Benz engineers use the crankshaft position sensor to know which cylinder has stopped closest to the optimum position for re-starting the engine. The engine control module then re-fires that cylinder first, an action that helps smooth out and quicken the re-start event.

2012 Mercedes-Benz SLK engine

To prepare for our drive, we needed to store two large duffle bags and wondered how much room our SLK350’s trunk provided. Mercedes-Benz literature claims 6.4 cubic feet with the roof lowered and 10.1 cubes with the roof raised. Since we would soon be driving from sea level through the clouds to the observatory at Teide National Park, some 7,800 feet above the Atlantic in Spain’s canary Islands, the top would be down and up depending on the precipitation (or a lack thereof). The trunk easily swallowed two large backpacks and a camera case with the roof stowed. Nifty.

The SLK’s hallmark retractable hardtop comes in three varieties: solid steel panels, a tinted roof section or with Benz’s trick new Magic Sky Control electrochromatic roof section. The later roof’s trick is that the transparent panel can shift its tint from almost clear to heavily darkened.

The glass section is a glass-matrix polymer-glass sandwich in which nearly microscopic rectangular particles are suspended in carrier-type fluid. When a small electrical charge is put through the polymer layer, the particles obediently arrange themselves in a vertical orientation, letting light pass through mostly unencumbered. When the juice is cut via a switch on the windshield header, the particles rotate 45-degrees, blocking most of the light (and heat) attempting to pass through. The shift requires nary a second. (Geek Note: Magic Sky Control uses a similar principle to Delphi’s Magnetic Ride Control dampers that control the flow path of damper fluid.)

When it came time to press the starter button and head for the observatory, temperatures were mild, and low clouds hung over our oceanfront starting point. With rain threatening, it neither felt nor looked like top-down driving weather, so the top stayed in place.

The imperfect roads on Tenerife presented a less-than-ideal surface that worked to shake and rattle the SLK. It accomplished neither. The roadster easily absorbed the punishment with the aplomb of a true fixed-roof coupe. Interior noise levels (engine, road and wind) were well subdued, and the exhaust note of the V6 sounded sportier than the same mill in the C-Class sedan. No surprise there, but still a welcome discovery.

Short-wheelbase cars can feel skittish, but the SLK simply doesn’t. Even at full throttle with every foot-pound of torque twisting the rear half shafts, the SLK350 felt unshakable and secure.

As we left the island’s primary roads for the twisties ascending the extinct volcano’s walls to the observatory, the SLK’s locked-down feeling continued. Our route took us into the clouds that were heavy with moisture and the narrow roads turned slick. It seemed that the entire ride up the mountain was a Falling Rock Zone, and plenty of rocks littered the asphalt – like we needed more excitement.

Even running uphill, the 302-hp six-cylinder had plenty of power in reserve. Thinking that leaving the electronic stability control in the ‘On’ position was a good idea, we’d often feel it working to keep the SLK in line. As expected, it immediately curbed any oversteer, but did so in a way that wasn’t retaliatory – it simply chided for being overexuberant.

What was unexpected was the so-called torque-vectoring function of the Electronic Stability Control. When diving into a corner under braking, we’re trained to expect a certain amount understeer – particular from Mercedes. The SLK senses the understeer and helps to mitigate it by adding a measured amount of braking to the inside rear wheel, helping to increase the car’s yaw rate and make it rotate more easily.

We’ll have to wait for the AMG-tuned version of the SLK to arrive before this chassis can be completely exploited, but indications are good thus far. Unfortunately, the ESC on the SLK350 cannot be completely disabled. When the dash switch is toggled off, the tires will spin to aid acceleration on snow or through mud, but any yaw immediately triggers a throttle intervention. When the AMG version arrives, expect an option to completely shut down the ESC.

Even with ESC on, the SLK remained a remarkably fun steer. The traditional hydraulic rack-and-pinion box had a natural on-center feel. Rolling off of center, starting at about 5 degrees, the box cranks the wheels with a constant ratio. At 100 degrees of steering angle – just beyond a quarter turn and just before your arms get crossed up – the ratio increases and the wheels turn more quickly. This is a huge help on roads that twist enough that you spend as much time looking out the side glass as the windshield. On the roads of Tenerife, we rarely had to shuffle the wheel or get our arms completely crossed-up.

Somewhere north of 6,000 feet we broke through the clouds and the top went down. It was chilly enough for us to turn on the Airscarf, a feature that blows warm air on your neck. We also put up the Airguide windstop. With the heater cranked up, we remained warm in the cabin, and buffeting was kept to a minimum.

After shooting some photos, we headed back down the mountain. This strained the brakes, as evidenced by the soft pedal and burning odor. However, the Continental SportContact5 tires (225/40R18 front and 245/35/R18 rear) – known for their ability to shed speed with authority – never faltered. The average SLK driver probably isn’t going to give their drop-top the same workout, so for daily duty, the standard stoppers should do nicely.

In all, the 2012 SLK’s driving experience was a good one. It did, however, leave us wondering about a few things. First, we’re looking forward to some time behind the wheel of the lighter SLK250. The tonnage is down by more than 100 pounds and weight distribution should be closer to 50/50. The SLK350’s smaller-engined sibling could end up being the better of the two offerings – that is, until the V8 AMG model enters the mix. We’ll let you know as soon as we get the chance to try them out.

Study reviews break-even point for hybrid vehicles


Buying a hybrid is a responsible environmental move but, given their premium over standard cars, they aren’t always a money-saving purchase. A study by CarGurus showed that gas would have to top $7 a gallon to make most hybrids the economical choice.

Hybrids command, on average, a 17-percent markup over their standard-powertrain counterparts, which stunts their economy at the pump. The $7-a-gallon break even point is an average. For some cars, the break-even is point is even higher. For a Cadillac Escalade Hybrid to make you money, gas will need to climb to $15 a gallon.

On the lower side of the scale are the Toyota Camry Hybrid and Ford Escape Hybrid. The Toyota’s break-even point came out to $4 a gallon, while the Ford bucked the trend, breaking even at $2.50 a gallon.

First Drive: 2011 Aston Martin V8 Vantage S

http://www.sportscarsfans.com/images/script/image.php?id=A028_4D8C86A0

Nestled in a secluded valley in the south of Spain is the Ascari Race Resort. Celebrated as one of the world’s most beautiful tracks, the private 3.2-mile ribbon of perfectly smooth blacktop challenges drivers with 26 corners, 10-degree climbs and 18-degree banks as it weaves through the mature oak trees that dot the landscape. Named after Alberto Ascari, the first double world Formula 1 champion, the well-manicured decade-old venue is the type of circuit enthusiasts fantasize about.

Our private shuttle takes us through the manned guard gate towards the main clubhouse. As we round the corner, and head down the shallow hill, the sun reflects off something in the distance. Parked in the paddock are a dozen glistening sports cars – some coupes, some roadsters – each still dripping wet from the overnight shower that leaves the air fresh and crisp. The vehicles, the latest offering from Aston Martin, are the enthusiast-targeted Vantage S Coupe and Roadster.

Nine times zones from home with jet lag extinguished by a morning cafĂ© grande, I figure it is time to get behind the wheel. Only one thing is more enjoyable than driving the new Aston Martin Vantage S through the mountains of Spain – spending a long afternoon with the sports cars on the wide-open Ascari race circuit.

The Aston Martin Vantage secured its position as the automaker’s sportiest model when it was introduced at the 2005 Geneva Motor Show for the 2006 model year. Like the DB9, the then-new two-door utilized the now common VH Architecture (the chassis is constructed with extruded and bonded aluminum panels). Today, the platform is also shared with the DBS and Rapide.

The four basic body styles in the Aston Martin lineup have much in common, but the Vantage holds the trump card when it comes to handling. Unlike its architecture-sharing siblings, the Vantage is shorter by a foot and its wheelbase undercuts the others by nearly six inches – the reduction in overall size translates to a lighter curb weight (3,549 pounds Coupe, 3,726 pounds Roadster) and greatly improved handling.

Aston Martin offers its Vantage in a dozen flavors these days, from the entry-level V8 Vantage Coupe ($120,350) to the flagship V12 Vantage Carbon Black ($194,995). Following on the heels of the limited-edition sport-tuned V8 Vantage N420 models, introduced less than a year ago, are two new models both wearing the automakers coveted ‘S’ badge - the 2011 Vantage S Coupe and 2011 Vantage S Roadster.

While their aluminum platforms are virtually identical to the standard coupe and roadster models, the British automaker is targeting driving enthusiasts with these heavily upgraded Vantage S variants. Under the hood of each is a specially-tuned version of the familiar all-alloy 4.7-liter V8. Fitted with an adjustable air intake (engineered to open nearly unrestricted at 3,500 rpm), more aggressive spark mapping and the ability to take advantage of higher octane fuel, the engine delivers 430 horsepower at 7,200 rpm and 361 pound-feet of torque at 5,000 rpm (its power rating tops the N420’s output by about ten horsepower). We estimate the Vantage S will hit 60 mph in about 4.5 seconds (Aston Martin lists the maximum speed at 189 mph).

The Vantage S also boasts a new transmission. The six-speed Sportshift gearbox (a single-clutch automated manual transmission) fitted to the standard Vantage models and the N420 has been superseded by Aston Martin’s all-new seven-speed Sportshift II. While it remains a single-clutch automated manual transmission (rumor has it a dual-clutch unit won’t fit), Sportshift II is 52 pounds lighter than Sportshift I. Plus, it is at least 100 pounds lighter than a dual-clutch transmission, reports Aston. Specifically designed with the performance of the V8 Vantage S in mind, the transmission is engineered to operate automatically in Drive mode, or to be manually commanded via column-mounted magnesium shift paddles (the new transmission is reportedly able to select gears 20 percent faster than the older gearbox, in both modes). The rear-mounted gearbox is also now air-cooled, not oil-cooled like its predecessor, helping to shed an oil pump and other unnecessary ancillaries.

The exhaust system is also unique to the V8 Vantage S (it shares some commonality with the aggressive muffler system used on the V12 Vantage). Its overall capacity is larger, and the bypass valves are engineered to open earlier in the rev range to produce a throatier sound and more “crackle on the overrun,” says the automaker.

The steering rack has been modified with a quicker ratio (now 15:1, as compared to 17:1 on the standard Vantage models), dropping the number of wheel turns (lock-to-lock) down to just 2.62. The suspension has also been overhauled with retuned passive damper valves, revised rear spring coil rates and revised bump stop rates and lengths.

The braking system delivers more stopping power, thanks to larger 15-inch slotted front rotors with six-piston calipers. While their overall diameter has increased over the standard Vantage, their weight has done just the opposite (credit an innovative two-piece system that uses a lightweight aluminum hub with a durable iron braking surface). The rear 13-inch rotors are cast iron, with four-piston calipers. The braking software has been refined to take advantage of existing brake-related systems (ABS, electronic Brake Force Distribution, Traction Control and Positive Torque Control), and the three-mode Dynamic Stability Control has been specially calibrated for its new enthusiast-tuned role. The Vantage S is also the first Aston Martin to be configured with Hill Start Assist (the brakes are automatically used to hold the vehicle stationary on a steep grade for two seconds, or until the accelerator is pressed).

Visually differentiating the Vantage S from its other siblings, Aston Martin has resculpted the front bumper and added a carbon fiber lower front splitter (its larger intake channels more air to the engine and brakes). There are larger side sills with styling derived from the GT4 race car, and a new carbon-fiber rear diffuser. Lastly, the rear decklid features the slightly raised “flip” shared with the V12 Vantage. All of the design elements contribute to lowering the coefficient of lift and drag, thus increasing high speed stability.

The wheels are also unique to the Vantage S lineup. Standard fitment is 19-inch “V-spoke” cast aluminum alloys, wrapped in Bridgestone Potenza RE050 performance tires (245/40R19 in the front and 285/35R19 in the rear - the rears on the Vantage S are 10 mm wider out back when compared to the standard Vantage). Forged 10-spoke aluminum alloy wheels, saving additional unsprung weight, are optional.

A glance at the interior reveals that it, too, has its own unique look. The cabin has been upgraded with distinctive three-track stitching on the door panels and seats (Aston Martin says the design element “echoes the gills of a shark”). The steering wheel can be covered in Obsidian Black leather (or Alcantara) with matching or contrasting stitching and there is an option to specify a Piano Black package, complete with a piano black center console, door handle surrounds and handles. The option list for both Vantage S models reads nearly identical to the other Aston Martin siblings, whether one is seeking a 1000-watt Bang & Olufsen BeoSound audio system, satellite radio upgrade or a boot-mounted umbrella. Track junkies overseas will want to opt for the extra-cost carbon-fiber and Kevlar bucket sport seats, with soft leather faces, saving nearly 40 pounds of weight (sadly, the DOT won’t certify them for the States).

Aston Martin is offering the 2011 Vantage S in two body styles. The standard V8 Vantage S Coupe (with mandatory Sportshift transmission), starts with a base price of $138,000. The V8 Vantage S Roadster with a power-operated soft top (also only fitted with Sportshift) will set you back $151,000. The pricing puts the two new models comfortably mid-pack in the Vantage lineup. (All pricing includes gas guzzler tax, but exclude the $1,615 fee for delivery and destination.)

By luck of the draw, I’m on the track in the first round. My fortune is short-lived, however, as I quickly realize my dallying in the heated lounge has cost me first choice of vehicles – I’m left holding the glass key to a bright blue right-hand-drive model. The minor annoyance accepted, my six-foot, two-inch frame settles comfortably into the optional sport seats (as mentioned, the nice carbon/Kevlar buckets won’t be offered in the States). Strapped in place with the standard three–point belts, I slide the white open-face helmet over my skull. I have plenty of wiggle room.

The new Sportshift II, like its predecessor, doesn’t have a traditional PRNDL gate on the lower console. Instead, there are four round buttons (”Sport,” “R,” “N” and “D”) high on the center stack. The Vantage S, like all Aston Martins these days, is started with the signature key held in place for a few seconds. The V8 fires over and settles to a tempered growl. I step on the brake and tap the “D” button, followed immediately by the “Sport” button – it electronically changes transmission maps so the new gearbox will shift more rapidly and hold each gear longer through the counterclockwise sweep of the tachometer. The sport mode also alters the flapper in the exhaust to give it a more aggressive note.

With an open track beaconing, and a flagman waving a bandera verde, I bury my right foot on the metal accelerator pedal. There is a very reassuring growl from the ass-end of the coupe as the 4.7-liter forces me back into the seat.

It takes about three full laps of the 3.1-mile circuit before I am comfortable with the layout. There are twenty-six corners, so much of the orientation is spent memorizing entry points (speed will come). With most committed to my internal RAM, I increase my velocity gradually. I immediately find the Vantage S very docile - it is nearly perfectly balanced (49:51 front to rear) and the steering is nicely weighed. I’m pleasantly surprised.

After ten minutes, I’m starting to really enjoy things. The Bridgestone Potenza tires are getting some good heat into them, as are the brakes. I push harder. At about eight-tenths, the Vantage S transforms from being a street car on a track to a showroom-ready racer. The back end starts to break free if power is applied on a lightened rear end (easily corrected with some opposite steering input) and a bit of understeer in the sharper corners becomes an issue. It’s time to crank things up.

At nine-tenths, I’m grinning ear-to-ear. Diving into the hairpin corners, I use trail braking to help rotate the Vantage S (masking much of the understeer). Body roll is minimal, and there is plenty of low-end torque to control rotation and bring the coupe back to speed upon exit. The width of the Vantage requires some caution in the tighter areas (unless you enjoy unsettling impacts with curbs), but nothing overly distracting. That same low stance does contribute to ample, and welcomed, grip on the small and medium-size corners. On the larger sweepers, I find it easiest to keep my foot down until I feel the rear end get light. Then I just hang it there and enjoy the ride.

The Vantage S is truly one of the more enjoyable vehicles I have ever driven on the track. The engine pulls with gusto (it prefers to spin at the top of the tachometer, so be wary of the fuel cutoff), the exhaust sounds tremendous (even through a helmet) and the brakes are more than competent for the job. And one has to mention the chassis – it is a spectacularly stiff platform. Aston Martin takes some abuse for using the same VH architecture on all of its models. I say, who cares? It works.

Yet hold your applause.

Even with its sexy styling and eight-cylinder rumble, there is something working against the Vantage S. It’s the darn brand-spanking new Sportshift II gearbox. While it is admirably lighter and quicker than its predecessor, it still trails the pack when compared against the dual-clutch offerings from the competition (there is no prize for inventing the ultimate VHS machine these days). Even when the transmission is in manual-shift mode, there is an agonizingly noticeable delay between gears. Aston Martin’s redesigned single-clutch gearbox may finally be quickest of its kind, but the industry moved on. Several years ago.

With my helmet back in the lounge, I grab the keys to another Vantage S and depart Ascari Circuit on two-lane public roads for the small Spanish villages of Cuevas del Becerro, Setenil de las Bodegas and Arriate. In a relaxed manner, the transmission is left in “D” allowing the electronic nannies do the shifting. Once again, I find myself flustered with the slow gearbox, so it’s back to manual mode (thankfully, it only takes a brief tap on the paddleshifter to kill the autobox and the system doesn’t revert back to automatic without pressing the “D” button again). With my brain in control, and my fingers doing the work, the Vantage S is a fun scalpel to carve local Spanish roads. I am smiling once again.

2011 Aston Martin V8 Vantage S rear 3/4 view

The British automaker doesn’t hesitate when asked to put the crosshairs on the Vantage’s direct competition. It understandably comes from the volume-selling rear-engine Porsche 911. Granted, Aston Martin money ($138,000-plus) will buy every single naturally-aspirated 911 in today’s lineup, and get you in a standard 911 Turbo – an established segment benchmark.

Aston Martin Vantage S verses Porsche 911 Turbo. That’s a tough dilemma.

If asked to choose a weekend track car with those lottery winnings, I’d toss both aside and place my money on the Porsche 911 GT3 RS – that lightweight slot car is a no brainer. But, if asked to pick a sports car to fill the void in the third garage slot, one that would shuttle me to work a couple days a week, get front billing with the valet at the country club, provide me with an engaging driving experience up Mulholland Highway on days off and make me look over my shoulder each time I park, I’d choose the new Aston Martin Vantage S. But, really… can I get one with a manual transmission?
