History

As from 1999 the new BMW Alpina B3 3.3 came for the new E46 series. In 1998, a prototype using the 3.2 L engine from the B3 3.2 was previously unveiled at the Birmingham Auto Show. The production model was formally presented at the 1999 Geneva Motor Show and the estate station wagon at the 2000 Birmingham Auto Show. 

The body base was initially offered by the 328i (M52TÜ) and later the 330i (M54). The following model variants were available: sedan, coupe, cabriolet (convertible) and the estate station wagon (touring version).

Nice interior with Alpina steering wheel and seats with logos.From 2001, the B3 was also offered in an all-wheel drive variant, which premiered at the Geneva Motor Show of the same year.  From 2002 the BMW Alpina B3 224 kW maximum power and 362 Nm maximum torque. Its premiere took place at the Mondial de automobile 2002.

For both E46-B3 models, Alpina used the E36-US-M3 cast-iron engine block (S52B32/US) as the basis and modified it, since both the M52TÜ and the M54 engine block were not suitable for it.
