In General, the transformation of the four-door BMW 8 series into a supercar went according to the recipe already tested on the BMW M8 coupe. The sedan received the same 4.4-liter twin-turbocharged V8, developing, as expected, 600 HP as standard and 625 HP in the Competition version. Like the two-door, the amount of thrust in both cases is 750 Nm.
The engine works with the same 8-band automatic and all-wheel drive system with an active differential, originally borrowed from the BMW M5. And the BMW M8 Gran Coupe accelerates exactly the same as the two-door: the first 100 km/h the basic version will gain 3.3 seconds, the more powerful one will spend 3.2 seconds on the same. the Maximum speed in both cases is limited to 250 km / h, but for a surcharge you can remove this restriction, and the sports car will accelerate to 305 km / h.
The sedan body is reinforced by additional elements and struts. The suspension has new components with increased rigidity, reinforced stabilizers and adaptive shock absorbers from BMW M with three modes of operation. In addition, the BMW M8 Gran Coupe received a new steering mechanism and powerful brakes with 380 mm discs and the possibility of replacing them with carbon-ceramic.
Exterior chetyrehdverki modified in the same style as the coupe: aggressive bumpers, extended wheel arches with 20-inch wheels, diffuser with four exhaust tips, new mirrors aerodynamic shape and optional carbon package. The differences were, perhaps, only an extravagant spoiler on the trunk lid and a composite roof in the basic configuration.
In salon-M-chairs, M-a wheel, M-a joystick of the automatic machine, M-overlays on thresholds and M-finishing with carbon fiber. In addition, the M8 Gran Coupe is equipped by default with a 12.3-inch digital instrument panel and a multimedia system with a 10.25-inch monitor.
Production of new items should start in November, but the acceptance of orders in some markets has already begun. In addition, BMW announced a special starting version of the sedan, which will be distinguished by a unique green body color with bronze accents, special wheels and door sills, as well as the original color scheme of the leather interior.
