six-cylinder models, the E36 was launched with the then-new BMW M50 DOHC petrol engine. In late 1992 the M50TU versions added single-VANOS (variable valve timing), which increased torque (peak power was unchanged). In 1995, the BMW M52 engine replaced the M50TU, resulting in the 328i model replacing the 325i and the addition of a new mid-range 323i model (powered by a 2.5 litre version of the M52). In 1992, the 3.0 L BMW S50 engine debuted in the E36 M3. In 1995, its capacity was increased to 3.2 L. Diesel Initially, the turbocharged straight-six BMW M51 engine was used in the E36 325td model. In 1993, the 325tds model was released, which added an intercooler to the M51. In 1994, the 318tds model was introduced, powered by the four-cylinder BMW M41 turbocharged and intercooled engine. Diesel engines were available only in sedan, touring and compact body styles. The coupe and convertible had only petrol engines. Drivetrain The E36 was produced with the following transmissions: 5-speed manual (1994-1999 M3) 6-speed manual (1996-1999 M3- except for the United States) 4-speed automatic 5-speed automatic This is the first model (from BMW or any other make) with rear-wheel drive, since the E36 was not produced with all-wheel drive (unlike its predecessor and successor). Suspension The sedan, coupé, convertible and Touring models use the "Z-axle" multilink suspension in the rear, which was introduced in the BMW Z1 roadster. The hatchback ("Compact") models use a rear semi-trailing arm suspension based on the older E30 3 Series design. This was done in order to save space due to the truncated rear end of the hatchback. M3 model The E36 M3 was launched in 1992 and was powered by the BMW S50 and BMW S52 straight-six engines rather than the four-cylinder units used in the E30. Unlike the predecessor, the homologation special type ended and it was not developed expressly with competition in mind. It was produced in coupé, sedan, and convertible body styles. Alpina models The Alpina B6 2.8, B3 3.0, B3 3.2, B8 4.0 and B8 4.6 models were based on the E36. The B3 and B6 models were powered by straight-six engines, while the B8 models were powered by V8 engines. E36/5 Compact The 3 Series Compact range of three-door hatchback models was introduced in 1993, based on a shortened version of the E36 platform. The model code for the hatchback body style is "E36/5"
