Mercedes-AMG S 65 Coupe (C217) 2017-Present Photos, engines & full specs

When the 612 hp provided by the 4.0-liter biturbo S63 AMG was no longer enough, the German carmaker offered the 6.0-liter V-12 biturbo engine and upgraded the badge as well.

The horsepower battle was nowhere near its end in 2017 when Mercedes-AMG introduced the S65 Coupe. It might have looked like its less-powered brother, but it was a different kind of animal that could breathe with 50 percent more cylinders and displacement. At least, it kept the same number of turbochargers.

From the outside, the big and fast Coupe featured an aggressive grille, inspired by the AMG GT model, with 14 chromed vertical slats. The front apron was divided into three air-intakes: a centrally mounted wide grille and two side pods to cool the brakes. The side sculptured profile on the fenders and doors amplified the car's dynamic profile, which was built on a shortened S-Class platform. In the back, the slim LED taillights took their inspiration from the same AMG GT.

Inside, the front sport seats were wide and comfortable, with adjustable side bolsters. The two seats in the back offered enough legroom and headroom for adult passengers. The S65 Coupe was a true 2+2 vehicle. For the instrument panel, AMG S65 Coupe featured a 12.2" wide-screen color display that reproduced the round dials of a classic instrument cluster.

Under the hood, AMG installed a 6.0-liter V-12 helped by a pair of turbochargers. It produced 1000 Nm (738 lbs), which was more than some trucks' engines. Unlike its brother, it could provide 630 hp, which didn't seem too much of an improvement, but its high torque was impressive.
