Alpina is back! Sort of! Meet the 600 horsepower, BMW M4-based Bovensiepen Zagato. Despite being based on the G83 M4, or in lay terms the M4 Competition Convertible, we’re quite sure the Bovensiepen Zagato will behave quite differently from behind the wheel. Power has been cranked up to 611 horsepower and 700 Nm (516 pound-feet), and Bovensiepen says the car accelerates from zero to 60 mph in 3.3 seconds; that’s a third of a second more than the droptop M4. In this vide, you can hear exclusively the sound of the Bovensiepen car with the Akrapovic exhaust! #bovensiepen #zagato #bmwm4
