Today, the most powerful Mercedes-Benz model you could get is probably the twelve-cylinder S65 and Maybach S650 – as both models have an output of 621 horsepower. However, VATH decided that they would produce something beefier than that, as they took both the coupe and cabriolet versions of the C63 and worked on their 4.0 liter biturbo V8 engine so they could give out a lot more power.
After VATH worked its magic on the C63’s AMG engine, it no longer gives out just 503 horsepower in the S specification. Instead, the V8 engine can now produce as much as 690 horsepower. This V63RS package, which includes the 187 horsepower boost, will cost you right around €12,800 (or $15,900), and that does not include value added tax yet. The upgraded engine is paired to a seven speed automatic transmission. Other upgrades include a new turbocharger setup and downpipe, together with an uprated oil cooler for the engine.
It isn’t just the horsepower that gets a boost, but of course, the torque as well. Before it has been modified, the C63’s standard was 516 pound feet (700 Newton metres), and now, it has as much as 664 pound feet (900 Newton metres) of torque.
Now with its beefier V8 engine, it only takes 3.3 seconds for the C63 S to hit 62 miles per hour (100 kilometers per hour) from a standstill. This makes it six tenths of a second faster than the regular coupe. To compare its top speed from before, the standard C63 S’ maximum speed was 180 miles per hour (290 kph) due to its electronic limiter. Now, it can go over 211 mph (340 kph) with the optional AMG Driver’s Package.
That’s not all that VATH did though, as it now gave the C63 its own unique sound with the customized exhaust system. This option can be had for an additional €3,440 ($4,300), together with the larger 390 mm brakes for an extra €3,900 ($4,800), the new suspension kit for €690 ($850) then lowers your car by 40 mm (1.5 inches). What finishes off the look is the set of 20 inch wheels that require an attachment kit which will cost you as well.
So far, VATH has not shared any images of the C63’s interior. But what we know is that VATH can dial the speedometer to 360 kilometers per hour (224 mph) to keep up with the car’s increasing velocity. But this will cost you an extra €2,130 ($2,600), which already includes mounting. Heavy duty velour mats are also part of the package.
