BMW M4 Convertible spied on a final test run with a top down

Here we have the latest spy shots of the new BMW M4 Convertible, showing it with the same lightweight camouflage as on the prototype we saw in February near the Arctic Circle in Sweden.

This time the prototype has the retractable top down, with test drivers enjoying a sunny day near the Nürburgring.

Just as with the M3 and M4 Coupe, power comes from a 425bhp 3.0-litre six-cylinder in-line engine with M TwinPower Turbo technology with 550Nm of torque.

New six-speed manual gearbox with new throttle blipping function is standard, having lost 12kg compared to its predecessor. 7-speed M DCT will be optional.

The Coupe accelerates from 0-62mph in 4.3 seconds with the manual and 4.1 seconds with the optional 7-speed M DCT. The Convertible is expected to be a bit slower, due to a more complex and heavier roof system.

The M4 Convertible is expected to debut later this month at the New York Auto Show.
