410-hp drop-top 4 Series will give those dreaming of a M4 Cabrio something to consider.
If you’re loving the new lines of the BMW 4 Series Convertible, but need more than the 435i’s 300 horsepower turbo-six, Alpina has the solution. And it’s coming to the Geneva Motor Show. The aftermarket BMW tuner already offers the B4 Bi-Turbo that provides a real alternative to the M4 with the 3.0-liter twin-turbo inline-six upped to 410 hp and 442 lb-ft of torque. The B4 Bi-Turbo Cabrio will be introduced next week in Geneva, giving those that can’t wait for the M4 Convertible an immediate solution.
