The BMW Alpina B4 was a variant of the F32 4 Series that debuted for the 2014 model year. Powered by a N55 3.0L twin-turbo inline six modified by Alpina, it delivers up to 410hp in its early versions and up to 452hp in the B4 S Edition 99. Power is transmitted through an 8-speed ZF automatic transmission, with rear-wheel drive or all-wheel drive options. The Alpina B4 F32 offers an exceptional balance between performance, comfort, and elegance. Its specific suspension, its handcrafted interior with high-end leather and its grand touring character distinguish it from the most radical sports cars, positioning it as an ideal option for those seeking power with sophistication. The BMW Alpina B4 F32 was produced until 2019.
