GSC, short for German Special Customs, unveiled a tuning kit for the Mercedes CLS63 AMG. Called Mercedes CLS63 AMG Stealth, the German sports car gets a revised 5.5-liter V8 producing 750 horsepower and 1,150 Nm of torque, significantly more than the standard variant.

This makes the 0-100 km/h sprint possible in 3,7 seconds with the top speed limited at 350 km/h. Styling-wise, GSC provides new front and rear bumpers, LED daytime running lights, a revised hood, a rear diffuser, side air outlets, 20-inch alloy wheels with 255/30 R20 (front) and 305/25 R20 (rear) tires.

“A stealth CLS is definitely everything else but “inconspicuous”. Particularly if it pops up – as in the example shown here – in a luminary orange color from the Lamborghini Aventador color range,” says GSC.
