The 850CSi is a high performance variant of the 850i, and became the top of the range specification in 1992. Tuning the 850i's 5-litre V12 to a 5.6-litre V12, the CSi's engine was given a new engine code alongside a Bosch Motronic fuel injector.
Other improvements include stiffer suspension and dampers, reduced ride height, four stainless steel exhaust tips, four-wheel steering, uprated and ventilated discs, and a rear differential oil cooler.
Exterior alterations to the CSi include, reshaped rear and front bumpers for aerodynamics, and reshaped wing mirrors. The interior has two-tone leather and sport seats.
Production of the CSi ended in 1996, with the 5.6-lire V12 requiring extensive alterations to meet emission regulations for production to continue.
