History of the E-24 6-series coupe
During it's production, many changes were made internally and externally,though to the untrained eye, the outward appearance of the E-24 coupe remained constant.
Initially the bodies were based on the E-12 5-series platform, the earliest being built at the Karman factory and shipped by train to BMW for assembly. This quickly became a problem and by 1977 everything was done in Munich. The original 630CS was carbureted and had a 4-speed gear box which remained until 1978 when the 5-speed replaced it.
1979 brought the end of the non-injected fuel system and indtrodued the first computer management system. Also available at this time was the 'economy' version 628 CSi and the introduction of the ABS braking system as an option.
The E-12 platform remained until mid-1982 when the change to the E-28 5-series platform was indroduced. With a much improved suspension, engine, interior and a computer-based engine management system, the new 6-series also got subtle body changes: the front fender flairs were increased and the antenna moved from driver's front fender to passenger rear.
In 1988, the world-wide bumpers replaced the euo and US bumpers and made all the cars look the same. Airdams now had flush curve-edged fog lights as well.
April 6, 1989, the last E-24 coupe rolled off the assembly line.
During it's production, there were several 'specialty' models built. German tuners Alpina, Hartge, and Schintzer made high-performance models adding their own engine parts, suspension, wheels, interiors and more. Some of these were turbo-charged.
In addition, many dealers offered a convertible conversion as an option at purchase (or after) and though there is no number as to how many of these were made, several still survive.
