VATH-tuned Mercedes-AMG C63 V63RS delivers 690 hp

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.

Elegant understatement with 700 PS and 340 km/h: C 63 AMG Coupé and Cabriolet from VÄTH

VÄTH, the Mercedes specialist based in Hösbach in Lower Franconia, Germany, has recently tuned a Mercedes-Benz C 63 AMG Cabriolet and a Coupé. A perfect example of elegant luxury combined with exceptional power and performance!

The expert team fitted the racer with VÄTH's own V63RS tuning kit at a cost of EUR 12,800. The kit includes the VÄTH turbocharger with a new downpipe and the VÄTH oil cooler for the engine and gearbox. To complete the tuning, the ECU was reprogrammed on the dyno and the top speed was increased.

Following the adjustments, the engine – which has a displacement of just under 4 litres – is now capable of 513 kW or 700 PS and 900 Nm torque, enabling a Vmax of over 340 km/h. It can do 0 - 100 km/h in 3.3 seconds.

The VÄTH V 63 RS has its own unique sound – with the valve exhaust system, drivers can choose between a deep-throated, rumbling V8 biturbo or sonorous V8 sound at the push of a button. This sound experience is available for EUR 3440.

Thanks to the new performance values, the V 63 RS is crying out for the VÄTH high-performance brake system: powerful 6-piston fixed-caliper brakes with 390 mm brake discs exert a strong braking force on the front axle and ensure the shortest possible braking distance. The brake system, which also comprises braided stainless steel brake lines and sport brake pads along with racing brake oil, costs EUR 3900.

The team from VÄTH installed a thread lowering kit (by 20 to 40 mm for EUR 690) for a sporty yet comfortable and safe driving experience, which can be achieved in combination with the standard AMG Ride Control.

As an alternative, there is also a complete suspension kit for drivers who want the full sporty driving experience, comprising oil pressure shock absorbers and double-spring system. The rebound and compression stages of the shock absorbers can be adjusted. The height and hardness of the suspension can be adapted, enabling even more direct handling. This came to around EUR 3500 in total.

Precisely fitting "V2-GT" alloy wheels from VÄTH weighing just 11.1 kg (front wheel) and 13.5 kg (rear wheel) enable 255 tyres to be used for 8.5 x 20 inches and 285 tyres for 10 x 20 inches. The aluminium rims cost EUR 680 each for the front axle and EUR 720 each for the concave design on the rear axle. An attachment kit costing EUR 250 was also required for the new rims.

In the interior, the VÄTH team installed a speedometer with an extended scale up to 360 km/h, which cost EUR 1980 plus EUR 150 for mounting. Finally, the set of floor mats made of heavy-duty, black velour with the silver VÄTH logo cost EUR 190. [All prices herein are quoted before value added tax.]
