The B10 was built as a sedan and touring based on the BMW E39 from January 1997 to May 2004.

In February 2000, Alpina introduced the Alpina D10 Biturbo, the first six-cylinder diesel model produced by Alpina. The engine, a 3.0 litre twin turbocharged unit with 182 kW (244 hp) and 500 N⋅m (369 lb⋅ft) of torque, was based on the engine of the BMW 530d.It was at the time the most powerful diesel saloon in the world. High-pressure common-rail injection technology (the famous Bosch CP3 high-pressure pump) has revolutionized the diesel industry.

Engines

The third generation of the B10 was built with both six-cylinder and V8 engines.

The six-cylinder engines with 3.2 and 3.3 liters displacement were based on the 528i and the 530i.^[65] For the 3.3 liter engine the engine block was bored to increase displacement to 3298 cubic centimeters. The cylinder head was machined and a modified crankshaft was added, different pistons and camshafts were also used. A modified intake system enabled a higher rate of air flow, as well as a stainless steel exhaust system (Alpina-Bosal) with metal catalytic converters. The engine control unit was also completely revised, which increased the power to 206 kW (276 hp; 280 PS).

The two V8 engines with 4.6 (B10 V8) and 4.8 liters (B10 V8S) come from the BMW 540i. Again, a larger displacement was achieved by boring the engine block, which, together with other modifications, increased the power to 250 kW (335 hp), then to 255 kW (342 hp) for the 4.6 liter engine, and 276 kW (370 hp) through an increased stroke with the 4.8 liter engine.

Suspension

The original suspension from the BMW E39 has been reworked for the B10. Changes include modified springs and tuned shock absorbers from Sachs that help lower the car.
