History of the 8 Series

After a lukewarm reception from the then green-leaning German motoring Press, the first V12-engined 850is arrived here in October 1990 to a cautious reception.Performance of these 5.0litre cars was good but certainly not Porsche-threatening. This left potential buyers feeling a little underwhelmed by this all-new BMW supercar - or rather Grand Tourer, which is what it became. The styling was also thought to be a little too unimaginative yet most critics now agree it stood the test of time well. To BMW's credit, they listened to the market and released an updated car in May 1993, now renamed '850CSi', with the 'S' a desire to reinforce the sporty image suggested by the new six-speed gearbox. There was one other important ingredient in this improved recipe; a giant 5.6-litre engine. No longer could your £40,000 super coupe have its face rubbed in the sand by turbocharged upstarts, such as Ford's Escort Cosworth.At the same time, a realistic attempt was made to lift sales by expanding the range to two models, with the introduction of a less expensive version. The company's new 4.0-litre V8 was installed under the bonnet of this new automatic-only '840Ci'.In March 1996, BMW decided to rationalise the range. Imports of the 5.6-litre 850 ceased, while the 4.0-litre 840 was replaced by a car of the same name, and featured a new 4.4-litre V8, with manual or automatic transmission. Power remained the same curiously enough, but torque was much improved, as was acceleration, making it faster to 60mph than the original 5.0-litre V12 automatic had been in 1990. A mechanically identical 'Sport' version of the 840Ci was released at the end of January 1997, with lowered suspension, new wheels, 'M-Sport' mirrors and leather sports seats and the range was finally withdrawn from sale in June 1999, around the time the smaller Z3 M Coupe arrived.

BMW 8 Series Road Test

The twelve-cylinder versions, surprisingly enough, are slower than the later manual 4.4 V8s. Though top speed is the same electronically-limited 155mph, zero to sixty takes 6.6 seconds in a 4.4-litre manual, while the 5.0-litre V12 auto needs a still respectable 7.5 seconds. Hauling nearly two tonnes of luxury GT off the mark is one thing, stopping it safely is another. Fortunately, every 8 Series has ABS as well as excellent braking power, though pad life can be understandably short, if you drive enthusiastically.The main problem that these cars have always had is the infamous 'Servotronic' electronic power steering. The twelve-cylinder cars, in particular, can feel overly-light at higher speeds, making the driving a little unsettling. The ride too, may be too firm for those expecting a high-speed luxury car but for 90% of driving, such as traffic, motorways or just cruising and posing, an 8 Series is a pleasure to conduct.

Buying a BMW 8 Series

Electronics, in a word. Mechanically, BMWs last and last but the advanced computing power of the engine management system in early 850s could go west, leaving the owner staring at a four-figure bill to replace microchips and other associated 'brain' components. Major electronic failure is rare, though, and most problems will have surfaced in the first few years of the car's life. Never forget to check that the pop-up headlights lift and lower smoothly and that the electric roof, (self-lowering) windows, door locks and air conditioning are working perfectly too, as repairs will be expensive.
