BMW ALPINA B4 S BITURBO Coupé
The visual appearance of the B4 S Bi-Turbo Convertible is defined by short overhangs, muscular shoulders ending in a powerful rear end, and the characteristic BMW metal folding roof. The sporty and powerful design of the front spoiler features functional air intakes and forms a perfect aerodynamic match with the discreet rear spoiler. The soundtrack of the smooth 3-litre straight-six cylinder engine with twin turbochargers is best enjoyed with the roof down. It produces 324 kW (440 hp) and a maximum torque of 660 Nm which is sent to the rear wheels via an 8-speed sport automatic transmission. The BMW ALPINA B4 S Bi-Turbo Convertible accelerates from 0 to 100 km/h in just 4.3 seconds, reaching a top speed of 304 km/h. The combined fuel consumption according to the ECE norm is just 8.3 l/100 km and 190 g/km CO2.
