The first BMW M3, the E30, debuted in 1986. It's 'race-car for the road' pedigree was set out from early in it's development: like the BMW M1, production of the M3 road car was necessary to homologate the vehicle for racing, specifically the Group A Touring Car series where it would take on Mercedes-Benz W201.
The E30 M3 was introduced with a 2.3 litre engine derived from the M88 unit that had previously appeared in the M1 and M635Csi. The engine developed 192 bhp, offering 0-62 mph in 6.7 seconds and a top speed of 143 mph. The later Sport Evolution vesion incoporating a revised 2.5 litre engine developing 238 bhp, offering 0-62 mph in 6.2 seconds and a top speed of 154 mph.
The only panels that the M3 shared from the standard 3-Series were the roof and the bonnet. The M3 was equipped with a wider track for additional stability, and larger tyres for improved grip. The vehicle also sported a range of aerodynamic enhancements, notably the flared box fenders and the rear spoiler.
Several homologation specials were introduced during the E30 M3's six year production run: the Evo 1, Evo 2, and Sport Evolution. These models featured improved aerodynamics, improved brakes, and weight reductions.
Statistically, the BMW E30 M3 is the most successful road race car ever. The vehicle excelled in both domestic and international touring car championships as well as prestigious 24 hour events such as the Spa 24 hours and the 24 hours Nurburgring.
Approximately 18,000 E30 M3's were produced, 786 of which were convertibles, and 600 of which were the much sort after Sport Evolution model.
The E30 M3's production finally ended in 1992.
