The visual improvements done on the new SLK roadster include a new carbon front spoiler, a bootlid spoiler, a new rear diffuser, AMG-style tailpipes, and a new set of 20" tinted wheels with upgraded brake discs and calipers. Inside, Vath put in new aluminum sport pedals, Vath floor mats, and a modified instrument cluster, among other things.
For all the goodies that come with the aesthetic and aerodynamic modifications, the biggest part of Vath’s tuning program for the SLK includes power upgrades for all the engines in the SLK’s range, with the SLK55 AMG being the only exception.
The SLK200, with it’s 1.8-liter 4-cylinder engine, received a noticeable bump in output from the standard 184 horsepower to 210 horsepower and 229 lb/ft of torque with a new top speed of 150 mph.
Then there’s the SLK250, which is powered by a 2.1-liter turbocharged four-cylinder engine that produces 204 horsepower. After the Vath power upgrade was put in, the sports car received an increased output of 244 horsepower and 265 lb/ft of torque with a top speed of 155 mph.
Finally, there’s the 3.5-liter V6-powered SLK350, which saw its own power increase from the standard model’s 304-horsepower output all the way up to 330 horsepower and 288 lb/ft of torque with a top speed of 167 mph.
