The 2019 Geneva Motor Show not only saw the public debut of the ALPINA B7 Facelift, but also the first sighting of the BMW ALPINA B4 S BITURBO EDITION 99. As you might have guessed by its name, the special ALPINA is limited to 99 units and is available both in Convertible and Coupé versions, the latter also being offered with all-wheel drive (left-hand drive only).

For the special edition, ALPINA has even turned on the power screw together with Akrapovic delivering 12 additional horsepower from the inline six-cylinder engine: 452 hp drive the elegant two-door when the driver floors the pedals at speeds between 5,500 and 6,250 RPM.
There is certainly no shortage of torque: 680 Newton meters are available between 3,000 and 4,500 rpm and make the job of the 8-speed Switchtronic easier. In the case of the BMW ALPINA B4S Biturbo Edition 99 Coupe with all-wheel drive, the six-cylinder manages to accelerate the 1,750 kg car in 3.9 seconds from a standstill to 100 km/h.
The 65 kilogram lighter rear-wheel drive Coupe needs 3 tenths of a second longer, while the 1.9-ton convertible needs 4.3 seconds. All three variants reach more than 300 km/h top speed, with the specific numbers varying between 303 and 306 km/h.
In addition to the increase in performance, the BMW ALPINA B4 Edition 99 offers some eye-catching black accents, which can be combined with a matte wrap on request. There is not a large choice in color finishes: All 99 units leave the factory in either ALPINA blue, Sapphire Black, Mineral White, Fire Orange or Grigio Medio.
The Alpina B4 S seen in our photos is only painted in the lower part of the body in Fire Orange, the upper half of the exclusive special model shines in Dark Grey, which harmonizes very well with the 20-inch wheels in Ferric Gray. Large BMW Alpina logos on the front fenders bring additional motor sport flair and eliminate the last doubts about the sporting ambitions of this very special BMW Alpina B4 S.
