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 a capacity increase to 5.6 liters and power increase to 375 horsepower. The engine can be identified by the “Powered by M” inscription on the central cam cover between the two banks of cylinders.
The 850CSi’s modified suspension included stiffer springs and dampers and reduced the car’s ride height. The recirculating ball steering ratio was dropped 15% over the stock E31 setup.

Four round stainless steel exhaust tips replaced the square tips found on other models. The 6-speed manual gearbox was the only transmission option. In Europe all 850CSi’s came with four-wheel steering (AHK – Aktive Hinterachs-Kinematik).
