The heart of this high-performance vehicle, which was developed in-house at AMG, is its new 4-liter, V8 twin-turbo engine. It comes in two flavors: the GT with 340 kilowatts and the GTS with 375. Both offer vast power reserves even at low RPMs. The AMG GTS can accelerate from zero to 100 kilometers per hour in 3.8 seconds and has a top speed of 310 kilometers per hour.
