History of the BMW 850 CSI
As a top-of-the-range sports tourer, the 850CSi took over from the prototype M8. The 850CSi used the same engine as the 850i, which was tuned so significantly that BMW assigned it a new engine code: BMW S70B56. The modifications included a capacity increase to 5.6 litres and power increase to 380 PS (279 kW; 375 hp).
The 850CSi's modified suspension included stiffer springs and dampers that reduced the car's ride height. The recirculating ball steering ratio was dropped 15% over the stock E31 setup. The model also sported staggered throwing star wheels. The front and rear bumpers were reshaped for improved aerodynamic performance. 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, Active rear axle Kinematics), uprated and ventilated brakes with floating front discs, rear differential oil cooler, engine oil cooler, two-tone interior, sports seats, and reshaped mirrors. In the United States, the cars instead received "BMW Motorsport" writing on the door handles.
Production ended in late 1996 because the S70 engine could not be modified to comply with new emission regulations without substantial re-engineering.
