German Special Customs is back with another upgrade kit for the Mercedes-Benz CLS63 AMG. Dubbed the CLS63 AMG Stealth, it makes use of an uprated V8 5.5-liter twin-turbo engine producing 750 HP (551 kW) and 1,150 Nm (848 lb-ft), making it 225 HP (165 kW) and 451 Nm (332 lb-ft) more powerful than the 2012 stock model. Thanks to the extra oomph, it needs 3.7 seconds to reach 62 mph (100 km/h) and achieves a top speed of 217 mph (350 km/h).
It also comes with a KW coilover suspension featuring front-axle adjustable dampers and sits on 20-inch wheels with Michelin 255/30 R20 front and 305/25 R20 rear tires. There's also a new front bumper with built-in LED daytime running lights, a redesigned hood with air vent, different side skirts and fenders, four-pipe exhaust, along with a new rear bumper that has a carbon fiber diffuser and side air outlets.
The car is wearing a Lamborghini Aventador-inspired orange hue matched by the interior which is combined with a black finish and several carbon fiber inserts.
