Development of the B3 began in 2006 before the car was introduced in 2007. It utilised a modified version of the BMW N54 inline-six engine used in the 335i. The B3 was available with rear-wheel-drive or all-wheel-drive drivetrains. The engine was modified by the addition of an Alpina specific ECU, oil cooler and lighter and stronger MAHLE pistons. These modifications allowed the engine to generate 355bhp between 5,500rpm to 6,000rpm and 369 lb⋅ft of torque at 3,800rpm to 5,000rpm. The engine has a red line of 7,000rpm. The engine was mated to a six-speed ZF automatic transmission paired with a control system called Switch Tronic. Shift times had been significantly improved, taking 100 milliseconds to shift gears.

The car could be ordered in any colour from the standard exterior colours as offered on its predecessor. The exterior changes included optional Alpina pinstripes, a front spoiler with Alpina lettering, a rear lip spoiler and a light weight Akrapovic stainless steel exhaust system with quad exhaust tips. The exhaust system had a floating tip design, a first to be used on an Alpina vehicle. The interior included heated sport seats, wood trim, Lavalina leather upholstery, cruise control, Alpina floor mats and Alpina gauges with the speedometer reading up to 190mph on the European models. The interior could be customised to the customer specifications by the Alpina interior department. The suspension system of the B3 utilised a mixture of in-house developed components and BMW components. The B3 can accelerate from 0-62 mph in 4.8 seconds and can attain a claimed top speed of 177mph.

No. 052, this lovely petrol B3 Coupe was first registered on 18th April 2018 and is presented in black coachwork. Boasting only four former keepers and a low mileage for Alpina modes, showing a mere 73,200 miles from new. Offered with an MoT test certificate until March 2026, this well-maintained example had its last service in March 2025 where it was treated to new front brake discs. Described as having very good tyres all round and offered with two sets of keys, this is as collectable as it is enjoyable to drive. Consigned by Mathew Priddy
