The Mercedes SLS Roadster has one of the world’s most powerful naturally-aspirated V8 engines, a 570 horsepower 6.3 liter V8. German tuner VATH decided to find out what would happen if they add forced induction to the mix. So they went ahead and bolted a supercharger on AMG’s V8 and the result is, well, a colossal 702 horsepower and 850 Nm torsion torque.
Those bold power figures means this SLS Roadster is now one of the fastest of its kind in the world, with a 0 to 100 km/h sprint time of 3.6 seconds and a Vmax of 330 km/h. VATH has also fitted with car with enlarged gear box oil cooler, and bigger brakes with 405 mm steel discs. A stainless steel exhaust system with throttle control and sports catalysts is also available.
Other mods include fitting a set of three-part forged VÄTH wheels – 9.5×20 with 265/30-20 tires up front and 12×20 with 315/25-20 on the rear – and sports springs in addition to VATH’s own Ride Control software that lowers the SLS by 45mm. They also offer a nose-lift system.
Visually, the front spoiler, boot spoiler, side skirts, and brake vents are all made of visible carbon fibre, while the interior gets a new instrument cluster with 400 km/h speedo. You can choose between carbon or wood trims.
We are quite keen to know what this engine sounds like, now that the whine of a supercharger is added to the magnificent rumble of that V8.
Total cost of this tuning program for the Mercedes SL Roadster is 85.130 euro.
