The BMW E31 is the first generation of the BMW 8 Series. It is a grand tourer built by BMW from 1990 to 1999 powered by either a V8 or V12 engine. While it did supplant the original E24 based 6 Series in 1990, a common misconception is that the 8 Series was developed as a successor. It was actually in an entirely new model class aimed at a different market, with a substantially higher price and performance than the 6 Series.

The 8 Series debuted at the Frankfurt Motor Show (IAA) in early September 1989.

Sales of the 8 Series were affected by the global recession of the early 1990s, the Persian Gulf War, and energy price spikes. As a result, plans for the high performance M8 variant were dropped in 1991.

850i --------- THIS VERSION ---------
The 850i was the first model of the 8 Series launched in 1990 with the 5.0-liter M70B50 V12 engine having a power output of 300 PS (221 kW; 296 hp). It was available with either a 4-speed automatic or a 6-speed manual gearbox.

850Ci
There is some confusion over why and when the 850i became the 850Ci. The change happened around the introduction of the 850CSi and it is believed that BMW decided to include the "C" in the model name that denotes 'Coupe', just as two-door 3 Series cars alongside the 8 Series read 323Ci, 328Ci and so on.

850CSi
As a top-of-the-range variant of the 8 Series, the 850CSi took over from the prototype M8 variant. The 850CSi used the same engine as the 850i, which was tuned so significantly that BMW assigned it a new engine code: S70B56. The modifications included Bosch Motronic 1.7 fuel injection, a capacity increase to 5,576 cc (5.6 L) and power increase to 280 kW (381 PS; 375 hp) at 5,300 rpm[11] and 550 N⋅m (406 lbf⋅ft) of torque at 4,000 rpm. Road & Track recorded a 0-60 mph (0-97 km/h) time for the 850CSi of 5.9 seconds.

Production ended in late 1996 because the S70 engine could not be modified to comply with new emission regulations without substantial re-engineering.
