The Alpina B9 was built in a small series from November 1981 to December 1985 on the basis of the BMW E28. About 500 examples were produced.
Changes
The B9 is based on the 528i, whose M30-2.8-litre BMW engine was replaced by a 3.45-litre. Alpina tuned engine. The motor is based on the 3.5-liter version of the M30, but has been extensively modified. Alpina replaced the cylinder head, pistons, camshaft and modified the Bosch Motronic ECU. The engine transmits its power to the rear wheels via a 5-speed gearbox, an automatic transmission was also available. The suspension of the E28 has been modified with Bilstein gas dampers, as standard the B9 was delivered with 16-inch wheels (see picture).
