Alpina B4 History
History
The B4 debuted for the 2014 model year based on the BMW F32 4 Series coupe, powered by a reworked 3.0-litre N55 twin-turbo inline-six making up to around 410–452 PS depending on specification. Coupe and Convertible body styles were available, and a high-output B4 S Edition 99 limited edition was offered.
The second generation moved to the G26 4 Series Gran Coupé for the 2022 model year, dropping the two-door coupe and cabrio in favour of the four-door fastback exclusively. The B58-based 3.0-litre twin-turbo was tuned to 495 PS with standard xDrive. Production of both generations ended in 2025 as Alpina consolidated its model range within the restructured BMW Alpina brand.
