CONVERTIBLE
BMW ALPINA convertibles based on the BMW 3 respectively 4 Series have for many decades been enjoyed by a small and particularly loyal group of enthusiastic owners. The BMW ALPINA D4 Bi-Turbo Convertible continues this success, and fills a very specific niche. It offers abundant, effortless power and long-distance cruising ability in an elegant and stylish silhouette – regardless of whether the roof is up or down. Smooth power delivery, generous torque reserves and excellent refinement makes the powerful 3-litre six cylinder Bi-Turbo diesel engine ideally suited to the versatile BMW 4 Series Convertible with folding metal roof. Powered by 257 kW (350 hp) and 700 Nm of torque, the D4 Bi-Turbo Convertible accelerates from 0 to 100 km/h in just 5.0 seconds on its way to a top speed of 275 km/h. The combined fuel consumption based on the ECE norm is just 5.9 l/100 km and 155 g/km CO2.
