Petrol The four-cylinder petrol engines used in the E36 range were initially engines carried over from the previous generation 3 Series: the
BMW M40 SOHC engine and the
BMW M42 DOHC engine. In 1993, the M40 was replaced by the
BMW M43 SOHC engine and the M42 was replaced in 1996 by the
BMW M44 DOHC engine. To retain a 50/50 weight distribution (on petrol models), versions fitted with the heavier, six-cylinder engines had the battery relocated to the trunk. For the 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 only available in saloon, touring and compact body styles. The coupe and convertible only had petrol engines. == M3 model ==
