The BMW 6-Series coupe had the rather unenviable task of following up on the Wilhelm Hofmeister-designed 2000CS, 2800CS and 3.0CS coupes, whose production ran from 1967-75 and was capped by the outrageous competition lightweight CSL “Batmobile.”
The new model range had to combine world-class performance with stunning elegance, and Paul Bracq was tasked with re-thinking BMW’s top-line car. The result was a squarer, more aggressive “shark-nosed” coupe, which would be built in various forms to 1989, culminating in the blisteringly fast M 635 CSi, which used the 24-valve M88 motor from the M1 and could hit 255 kmh in European tune.
Bracq followed the design cues from the previous BMW coupe, with a divided kidney grille, large greenhouse and broad hood and trunk, but the 6-Series had thin B-pillars, and the bodies were assembled by BMW at Dingolfing instead of Karmann’s Osnabruck works.
Handling remained by all-round coil springs and McPherson strut front suspension, semi-trailing rear links, and recirculating ball steering. New to the 6-Series was speed-sensitive power steering, four-wheel disc brakes, and a complete warning light system to alert the driver about engine and electrical systems. The 2+2 seating saw a driver-angled dash flow down to a console that also separated the rear bucket seats.
Engine sizes gradually increased and the 6-Series really hit a bullseye with the M635CSi, which appeared at Frankfurt in 1983. Apart from the 286 PS M1 engine, it had a limited-slip differential and the “track link” suspension from the big 7-Series sedans, which was designed to reduce oversteer. ABS brakes arrived at the same time, along with a five-speed manual gearbox or a four-speed ZF automatic.
Badged simply as the BMW M6, the M635CSi was equipped with twin air-conditioners (and a beverage chiller in the rear), hand-stitched Nappa leather interior with eight-way power front seats, and an eight-speaker sound system. Distinctive M6 details included M badges front and rear, a larger front air dam and rear spoiler, matching color side mirrors and BBS wheels. The cars were fitted with new ellipsoid headlights, which directed a more precise beam onto the road.
In all 5,859 M 635 CSi cars were built between 1983 and 1989, with 1,787 of those being the slightly detuned U.S. model BMW M6, so only 4,072 with the proper M1 engine.
This European example has been exported to Maryland, USA and reimported to Europe 3 years ago and undergone a restoration (some pictures in the gallery). It has a clean Carfax without any accidents and a complete service history.
