When BMW finally commences sales of the heavily anticipated 8-Series Coupe, it will offer the all-new flagship in two powerful engine variants – a petrol-powered biturbo 4.4 liter V8 unit and a diesel-fueled 3.0 liter biturbo inline six mill. Nonetheless, there are customers hoping that new BMW 8 Series would be offered with a V12 engine or a plug-in hybrid drive, but the German premium has no plans for those.
Carsten Groeber, vice-president of product management at BMW Group, was quoted by Australian magazine GoAuto at the 2018 Paris Motor Show as saying that a V12-powered 8 Series won't happen. The BMW 7 Series -- the M760Li xDrive in particular – is powered by a 6.0-liter V12 petrol engine that can provide 601 hp (448 kW) of output and 590 lb.-ft. (800 Nm) of peak torque. This allows the M760Li xDrive to dash from zero to 100km/h in just 3.7 seconds.
Groeber noted that the V8 engine and the in-line six unit already allows for a perfect weight distribution with the new 8 Series. Since the V12 engine is a very heavy mill, it would destroy this weight distribution, particularly making the front too heavy. He remarked that the V8-powered 8 Series is already a proper sportscar.
As for the plug-in hybrid version of the 8 Series, Groeber remarked that at this point, the flagship is already perfectly set up that a PHEV version won't be needed. Nonetheless, if demanded by the market, BMW may offer a plug-in hybrid version of the 8 Series.
For customers seeking a lot of power for the new BMW 8 Series, the M850i xDrive would be a perfect choice. This version comes with a biturbo 4.4 liter V8 mated to eight speed automatic gearbox. It delivers up to 523 hp (390 kW) of output and up to 553 lb.-ft. (750 Nm) of torque. This allows the M850i xDrive to sprint from zero to 62 mph (100 km/h) in only 3.7 seconds achieved a limited top speed of only 155 mph (250 km/h).
The second version will be the 840d xDrive with a diesel-fueled 3.0 liter biturbo inline six mated to an eight-speed automatic transmission. This mill can deliver 315 hp (235 kW) of max output and 502 lb.-ft. (680 Nm) of peak torque. BMW expects the 840d xDrive to complete the sprint in only 4.9 seconds while going as fast as the M850i xDrive (155 mph or 250 km/h).
After the 8 Series Coupe, BMW is planning to offer an sDrive rear-wheel drive variant. In addition, BMW will release an M8 Coupe, Gran Coupe and Convertible to the market, with power to be provided by a beefed up version of the 4.4-liter V8 engine.
