The BMW M635CSi was the brainchild of BMW’s Motorsport department and arrived to the market in 1984. Karmann manufactured the early 6-Series BMWs from launch in 1976 before BMW took production in-house. The engine was a development of the M1 supercar’s 3453cc, 24-valve, six-cylinder unit producing 286bhp, the increased power necessitating chassis improvements which included altered weight distribution, revised suspension, larger brakes and a limited-slip differential. There was also a close-ratio five-speed gearbox (or four-speed multi-mode auto) and a more luxurious interior, while outwardly this ultimate 6-Series model was readily distinguishable by virtue of its ‘M Technic’ body kit. Performance was impressive with the M635CSi being capable of reaching 0-62mph in around 6 seconds on its way to a top speed in excess of 155mph.
The car we have on offer today was built new by Geoff Steel Racing over the winter of 2015/16 with the aim to compete in the Peter Auto Heritage Touring Car series, from an original E24 shell purchased from Southern Italy as a full, road legal car in very good condition.
The vehicle was subject of a completely stripped body to bare shell and dipped, a T45 FIA specification cage fitted and a full engine restoration. The gearbox was replaced with a rebuilt FIA Group A specification box, and a new FIA specification 100 litre capacity fuel cell was added. The car currently runs with 310bhp and weights 1200kgs and is said to have passed full HTP check first time and papers issued. With a number of high placed finishes in the European Group A season, including an impressive 2nd at Spa in 2016 and 2nd at the Algarve classic in 2017, the would certainly be a contender in the right hands.
