Under the bonnet, the M8 will be powered by a new generation 4.0-litre twin-turbo V8 engine, which will be potentially shared with Jaguar Land Rover. For the M8, this engine will generate at least 450kW of power, with drive sent to the rear or all four wheels.
Based on the 7 Series' Carbon Core architecture, which is rich with high-strength steel, aluminium, titanium and carbon-fibre, the M8 is said to have a 0-100km/h time of under four seconds.

The British magazine claims that the 8 Series coupe will go into production in the early part of 2018 as a replacement of sorts for the current 6 Series two-door.
A convertible variant will join the 8 Series lineup in early 2019, while the M8 coupe is pencilled in for a debut in the second half of 2019.
The 840i is thought to be powered by a turbocharged 3.0-litre straight-six, while the next-generation 4.0-litre V8 turbo will service the 850i and M850. A 6.6-litre turbocharged V12 is said to be the motivating force behind the 860i.
