Just one trim is on offer for 2021: the E63 S. Its 4.0-liter twin-turbo V8 produces 603 hp and 627 lb-ft of torque, with only a nine-speed automatic offered to change gears. An AWD system is standard too, but it does give you the option of a RWD-only drift mode for when you want to be a bit more of a hooligan. Plenty of luxury features are thrown in, including a panoramic glass roof, adaptive air suspension, dual-zone automatic climate control, heated and ventilated front seats, and 64-color configurable ambient lighting. A 12.3-inch driver info display is complemented by a touchscreen infotainment display of the same size, boasting Apple CarPlay and Android Auto, SiriusXM satellite radio, navigation, and HD Radio. Connected to this is a 13-speaker surround-sound system from Burmester, while the options list throws up attractive offerings like massaging front seats, soft-close doors, and augmented video for the navigation system.
