The Alpina B3 G21 has been built since 2020.
The Touring, the most traded version: Alpina's B3 Touring transforms BMW's practical 3 Series wagon into a 462-horsepower sleeper that embarrasses supercars while hauling the family. The hand-built twin-turbo inline-six delivers 516 lb-ft of torque through BMW's xDrive system, achieving supercar acceleration in estate car clothing. Alpina's meticulous attention to detail shows in the hand-stitched interior, forged wheels, and subtle aerodynamic enhancements. Limited production and Alpina's boutique approach ensure exclusivity that mass-market M cars can't match. The B3 Touring represents the pinnacle of the practical performance car, offering genuine 186-mph capability with space for luggage and passengers. With wagons disappearing from American roads, the B3 Touring appeals to collectors seeking the ultimate expression of European automotive philosophy. Alpina's uncertain future makes these hand-built machines increasingly significant.
