The E24 6-Series was an impressive and beautiful sports coupé. With its effortless performance it was great for any long distance trip. The E24 model was a great success for BMW and was produced from 1976 to 1989. The models ranged from the base 628 CSi to the M635 CSi. With its ‘shark nose’ front end and stunning looks, the 6-Series really stood out.
Six years into production came the M635CSi (or M6 in North America and Japan). This was the BMW Motorsport-developed version of the E24, powered by twin-cam, 24-valve straight-six engines known as the M88 or S38; these were both derived from those used in the M1 supercar.
The M635 CSi had few visual clues to distinguish it from the normal 6-Series. Almost all body panels were shared with other E24s, including the body-coloured rear spoiler with black rubber lip. The only exception was the deeper front air dam fitted only to pre-facelift models, which was ribbed on the lower portion. There were also two M badges, one on the boot lid and one on the grille, though these could be omitted upon request. In addition, the rear-view mirror housings were painted in body colour instead of the chrome finish used on all other pre-facelift 6-Series. Finally, cars equipped with the optional cross-spoke alloy wheels (in either the early or later version) had body-coloured wheel arch extensions.
The interior of the M635 CSi was also much like that of a standard 6-Series. The only truly unique item was the instrument cluster containing a 280kph/170 mph speedometer and a special tachometer with the M logo instead of an economy meter. In addition, every M635 CSi was fitted with the three-spoke M-Technic steering wheel (unless equipped with the optional driver's airbag) and the same sport seats available in other 6-Series models. Finally, the battery of the M635 CSi was mounted in the trunk for better weight distribution.
In general, the level of standard equipment increased on the M635 CSi from year to year. Depending on the market and production date options included: cross-spoke alloy wheels, metallic paint, Shadowline exterior trim, headlight washer/wipers, various types of leather upholstery, air conditioning, rear air conditioning and storage unit, electric front seats with driver’s seat memory, heated front seats, electric sunroof, rear window sunblind, rear headrests, cruise control, and various audio systems.
BMW Motorsport developed five different versions of the M635 CSi: Two non-catalyst models for the European market (LHD/RHD), plus three distinct catalyst versions for Europe, North America, and Japan, which were all LHD. This example is one of the 3,283 non-catalyst cars produced in LHD for the European market.
Sable Brown Metallic, Nutria Buffalo leather, 17-inch AC Schnitzer alloy wheels, Electric tilt/slide sunroof, Electric windows front and rear, Electrically adjustable door mirrors, Factory alarm system, Rear head restraints, BMW sound system, BMW cassette radio, BMW overmats, BMW toolkit, BMW first aid kit (unopened), Alloy spare wheel, Spare key.
This striking E24 presents beautifully in the fantastic period colour combo of Sable Brown Metallic with Nutria Buffalo leather. Each side is finished with a contrasting pinstripe along the arrow-straight panels, complementing nicely both the car’s polished trim and subtler black detailing. The bodywork is in great condition overall, with no major signs of wear to report. There is a light dusting of chips to the ribbed portion of the front air dam, but elsewhere the bumpers are unscathed and the brightwork remains in fine original condition.
The charismatic interior is a welcome sight upon entry, the upholstery having aged to perfection. The textured grain of the Buffalo leather presents with a wonderful patina that can only be achieved with age. It has worn extremely well over time, and while the seats have clearly been used there is no damage to speak of.
A common issue with these 6-Series can be the temperamental ‘80s electrics but in this example the seats are manually adjustable. Items such as the electric windows and sunroof still function as they should and the switchgear remains feeling solid to operate. In the foot-wells you’ll find the original overmats protecting the carpets and in the boot you’ll find the alloy spare wheel, toolkit, and BMW first aid kit still in its plastic wrapping.
ENGINE & TRANSMISSION
The M1-derived 3.5-litre straight six erupts into life first turn of the key. Paired with a full stainless exhaust system fitted by DK Engineering the car sounds superb all the way through the revs. The engine bay is particularly tidy and appears amazingly original on close inspection. There are no hints of any corrosion or damage and all components present in fine fettle throughout. The most recent service was an Inspection II carried out at 81,500 miles.
WHEELS, TYRES & BRAKES
The AC Schnitzer wheels are, we think, a cracking period upgrade over the factory cross-spoke rims, and the fact that they don’t require costly TRX tyres is a real bonus. The alloys front and rear have a lovely deep dish, further accentuated by the polished outer rims. A perfectionist may note a little age-related wear present to each of the wheels but curb marking has been kept to a minimum. The alloys are wrapped in a matching set of Continental tyres providing excellent grip and feel on the road.
This M635 was first registered in June 1986. It was supplied new in Germany and was sold through Schmeink & Co, Bocholt. The car arrived in the UK in 2013 but has covered very few miles since that time, remaining in dry storage when not in use. The History File is complete with a handful of invoices from UK dealers such as BMW and DK Engineering. The dealer-stamped Owner’s Handbook/Service Booklet is also present and correct.
