Combining Alpina exclusivity with twin-turbo performance, the B3 S offers a compelling blend of pace, refinement, and open-top motoring.
The BMW Alpina B3 S BiTurbo offers a compelling blend of performance, refinement and exclusivity. Based on BMW's highly capable E93 3 Series platform, Alpina's enhancements transform the car into a more distinctive and sophisticated grand tourer, combining effortless pace with everyday usability.
Power comes from a twin-turbocharged straight-six engine, reworked by Alpina to deliver strong performance and impressive flexibility across the rev range. Combined with Alpina's chassis tuning and transmission calibration, the result is a car that feels equally at home on a long motorway journey or a more demanding B road.
Visually, the B3 S remains understated, with subtle styling revisions that set it apart from a standard BMW without compromising its elegant appearance. The folding hard-top convertible roof adds an extra layer of versatility, allowing the driver and passengers to enjoy open-top motoring while keeping the refinement and practicality of a coupe when closed.
As with all Alpina models, production was strictly limited, adding to the exclusivity of the B3 S. This particular example is number 250, as confirmed by the Alpina plaque within the cabin. With its limited-production status and performance capability, it represents a particularly desirable and collectible alternative to the standard E93.
Accompanying the car are its servicing folio, service booklet, Alpina owner’s handbook, and two sets of keys. September 2026 saw significant investment, with new brake discs, pads, sensors, brake fluid, and aluminium brake pipes fitted, alongside replacement rocker cover gaskets and a wheel refurbishment.
Further maintenance during 2026 included a spark plug service, gearbox oil exchange, and a 200+ point BMR checklist completed - all focusing on its continued upkeep.
Produced in limited numbers, the Alpina remains a rare sight on UK roads today. Blending performance, luxury, and exclusivity in a uniquely Alpina package, it represents an appealing alternative to more conventional performance convertibles of its era.
