Väth’s tuning kit is for the SLK 350, which in stock form, is powered by a 3.5-liter V6 petrol delivering a peak output of 302hp (306PS) and a maximum torque of 370Nm (272 lb-ft).
The revised software bumps output to 326hp (330PS), with torque climbing to 390Nm (288 lb-ft). As a result, top speed is lifted to 269km/h (167mph).
Vath then continues with a new sports exhaust system and an adjustable suspension that allows the driver to lower the car’s ride height from 20 to 65 mm.
The German specialist also cleans up the exterior with an aero package that installs a carbon fiber front and rear apron, side skirts and a boot lid spoiler, while the car now rides on 20-inch forged alloy wheels fitted with 235/30ZR20 tires on the front and 265/25ZR20 tires on the rear axle.
A carbon fiber trim kit for the interior rounds out the changes.
The complete package is priced at a rather hefty €25,192 or about US$32,900 at today’s exchange rates.
British designer Afzal Kahn took a Mercedes SLK 200 that had already been fitted with an extensive AMG sport package and then further honed by Brabus and added his own personal touch.
Among other new parts, the SLK 200 benefits from a flat black accent on the hood and the side air vents, carbon-fiber grille pieces and front splitters, red calipers, a Kahn sport exhaust system and new 20-inch matt black RS600 Kahn alloy wheels.
Under the bonnet, the SLK 200’s engine gains an extra 56-horses, while the roadster model rides on a lowered sport suspension.
The most powerful version of Mercedes-Benz’s small hardtop roadster, the 2012 SLK 55 AMG, will receive its world premiere at this year’s edition of the Frankfurt Motor Show in mid-September, but the first photos of the V8-powered model have already sprung up on the German car site Autobild.
Visually, the AMG treatment adds a new aero kit with bespoke parts up front and at the back along with a smoked out lights and larger set of light alloy wheels finished in black. Inside, you’ll find a pair of sports seats and plenty of surfaces covered in stitched leather
And while this is the first time we get to see the new SLK 55 AMG in the flesh and without camouflage, Mercedes-Benz recently shared details on the roadster model’s mechanical hardware.
Power for the roadster comes from a new naturally-aspirated AMG 5.5-liter V8 engine that delivers 62 more horses and 30Nm more torque than the previous model’s eight-cylinder unit, at 422-horses and 540Nm in European-spec, and 415-horses at 6,800 rpm and 398 lb-ft at 4,500 rpm in North American-flavor.
The aluminum V8 engine also features the AMG Cylinder Management system that can shut off four-cylinders from 800 to 3,600 rpm to improve fuel efficiency.
