The 2021 BMW Alpina B5 and D5 S, both of which are available as either a sedan or a wagon. The B5 is a gasoline model while the D5 S uses a diesel engine. Neither model will be sold in the US but the engine out of the B5 could eventually make its way into an Alpina version of the 8 Series Gran Coupe.
Under the hood, the B5 has a twin-turbo 4.4-liter V8 engine that produces 613 hp (457 kW / 621 PS) and 590 lb-ft (800 Nm) of torque. It enables the sedan to rocket from 0-62 mph (0-100 km/h) in 3.4 seconds and onto a top speed of 205 mph (330 km/h). The wagon accomplishes the same task in 3.6 seconds, while it tops out at 200 mph (322 km/h).
The D5 S, on the other hand, has a tri-turbo 3.0-liter six-cylinder diesel engine with 402 hp (300 kW / 408 PS) and 590 lb-ft (800 Nm) of torque. It allows the sedan to run from 0-62 mph (0-100 km/h) in 4.4 seconds, before hitting a top speed of 178 mph (286 km/h). The wagon is a tad slower as the dash to 62 mph (100 km/h) takes 4.6 seconds and the top speed is 176 mph (283 km/h).
Interior changes are modest, but include an Alpina-branded digital instrument cluster and a hand-stitched sport steering wheel. The models also have an individually numbered production plaque and customers can request “bespoke interior designs down to the smallest detail.”
The B5 starts at €117,700 for the sedan and €120,700 for the Touring. For the diesel-powered D5 S, the four-door goes for €92,500, and the wagon is €95,500.
