The BMW 8 Series (E31) is a luxury grand tourer produced by BMW from 1989 to 1999. It was the first BMW to be designed with a focus on aerodynamics, with a sleek and flowing body that helped it achieve a drag coefficient of just 0.29. The 8 Series was also one of the first cars to feature a fully digital instrument cluster, which was a revolutionary feature at the time. Underneath the elegant exterior, the 8 Series was built on a lightweight aluminum chassis, a first for BMW. This allowed for impressive handling and performance, especially when combined with the powerful V8 and V12 engines offered in the lineup. The 840Ci was powered by a 4.0-liter V8 engine, the 850i and 850Ci featured a 5.0-liter V12, and the top-of-the-line 850CSi utilized a tuned and more powerful version of the 5.0-liter V12. However, despite its innovative features and performance prowess, the 8 Series was a commercial flop for BMW. It was expensive to produce and sell, and it faced stiff competition from other luxury grand tourers like the Mercedes-Benz S-Class Coupe.

The 8 Series (E31) is now a highly sought-after classic car, known for its timeless design and impressive performance. The 850CSi, in particular, is highly prized by collectors, due to its limited production run and powerful engine.
