Cars can be completed with any of six engines, beginning from economic 4-cylinder for the Sedan 316i (the maximum speed of 200 km/h), the same 1.8-liter and finishing 6-cylinder 2.0, 2.3 and 2.8-liter, with system of gas distribution Vanos, and 5-staged RKPP or AT.
All engines have a longitudinal arrangement in a motive compartment and set back wheels in motion.
There was a model 320d (turbodiesel) dispersing to 100 km/h for 9.9 pages later. Thanks to increased by 60 mm to a track and on 30 mm to the wheel Sedan base it is very steady, however it caused modernization of a suspension bracket. Also the salon which is equipped with six auxiliary safety cushions is updated.
