Background
The E30 M3 was the first purpose-built motorsport BMW to be engineered and assembled in-house - and while most first projects are more about dipping a tentative toe in the water than first-time victory, the fact that the E30 M3 ended its career as the most successful touring car of all time is proof positive that BMW’s advertising strapline ‘The Ultimate Driving Machine’ wasn’t the usual marketing tosh.
It might have lasted just six short years but what a period it was: Launched onto an unsuspecting world in 1986, the M3 only made it onto public roads because Group A regulations insisted on 5,000 being built as proof that the cars in that class were genuine production models rather than the sort of highly-modified homologation specials we were used to seeing in, for example, Group B rallying.
And it had all the good stuff from the get-go: 200bhp might not seem like much now but back then the double-ton was The Holy Grail. It also had a beautifully balanced rear-wheel-drive chassis and was so visually understated as to make its performance even more of a shock to an unsuspecting M3 virgin.
The M3’s four-cylinder ‘S14’ engine earned its place under the bonnet thanks to its light weight structure and ability to rev more highly than its heavier six-cylinder counterpart. The 2.3-litre, 16-valve engine was programmed to reach a rev limit of 7,300rpm, delivering enough of a punch to make the most of that extraordinary lightweight chassis.
