"Europe's first turbocharged production car"

The 2002 turbo (E20) was launched at the 1973 Frankfurt Motor Show as the fastest version of the 2002.

The 2002 Turbo used the 2002 tii engine with a twin-scroll 0.55 Bar turbocharger developed together with KK&K. The cylinder head was a modified version of the '121T design, used on 1972 & earlier 2002s with larger combustion chambers to give a compression ratio of 6.9:1, in order to prevent engine knocking. A version of the Kugelfischer mechanical fuel injection was used with integrated boost enrichment feature and altitude compensation. The car had a larger radiator and an oil cooler as standard. This engine produced 170PS / 168HP / 125kW at 5.800rpm and 245Nm / 180 lb-ft at 4.000rpm.

Power transmitted to the rear wheels through a four speed strengthened Getrag 232 gearbox and a limited slip differential. As an option a close ratio five speed Getrag 235/5 was offered as on the BMW 2002Tii). Standard tire size is 185/70 VR13.

Suspension and braking system was similar to the 2002tii. There were McPherson struts and wishbones at the front and semi-trailing arms at the rear. Brakes are 258mm ventolated doscs at the front and 250mm drums at the rear.

The interior added an extra gauge cluster for the boost gauge & clock plus a red instrument panel with 240kmh/150 mph speedometer, sports seats & steering wheel.

The body featured a different front-panel with additional tow-bracket and air-intake apertures and the front & rear wheel arches are cut-back to allow fitting of wider wheels. These body changes are clothed in fibreglass wheelarch extensions and a front airdam, all bolted to the body, plus a rubber rear spoiler on the trunk lid. Two standard colours were available: Chamonix (white) and Polaris (silver). 2002 tutbos featured BMW motorsport colour-scheme stripes/decals on the sides & front spoiler. The early turbos had the famous "2002 turbo" reverse-legend spoiler graphic. This was considered provocative by the press, so BMW desoded to remove it.

2002 turbo was a very fast car for its time, but its power came on suddenly at 4,000 rpm, creating sharp oversteer, dangerous for the average driver.

The 2002 Turbo was introduced just before the 1973 oil crisis, therefore after only 1.672 cars built, the production ended in 1975.

Dimensions are: Length 4.220mm, Width 1.620mm, Height 1,410mm, Wheelbase 2.500mm. Weight is 1.080kg.

Top speed was 211km/h / 131mph and it could accelerate from 0 to 100km/h in 6,9 seconds.
