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.
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
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
