History of the 1992 - 1997 BMW 840
Model History BMW 8 Series E31
When the new 8 Series BMW (E31) was first sold in 1990, it was a new departure for the brand. This was a very powerful two-door coupe grand tourer, offered with either a V8 or V12 engine, and was BMW’s target car for an affluent buyer who wanted a sporty, statement car.
The BMW 850i was the first model to be released, initially with a four-speed auto, then (in January 1991) an optional six-speed manual gearbox mated to the 5L M70B50 V12 engine providing 300bhp. ABS and PAS were standard, and automatic stability control and electronic damper control were both available as cost options.
In 1993, the range was expanded to include the 840Ci using the V8, 286bhp M60B40 engine. The 850Ci, (that had been re-badged from 850i in September 1992) gained side impact protection and some more leather inside. At this time the 850Ci also increased engine size to 5.4L and a range-topping 5576cc V12 850CSi was also added, with the same specification as the 850Ci but with M Sport alloys, an LSD and healthy 380bhp. The 850CSi was discontinued in September 1994.
In January 1997 the range was changed again. The 840Ci now had a 4398cc V8 with a five-speed auto transmission and gained various trim upgrades. The 840Ci Sport was offered with the same engine but with M System II wheels, M Sport suspension, steering wheel, aero package and wing mirrors. Alpina also made a B12 5.7L manual with 416hp.
Today, the 850CSi is the most collectable model in the range, followed by the 5.4L 850Ci, the earlier 850 models then the 840 models. Lack of use is the biggest issue with many classics, especially those that have not been regularly serviced. Dash light issues can prove to be expensive and the plastic nose cone is vulnerable.
