M3 Convertible steps out

BMW UK has announced details of the third M3 derivative, the new BMW M3 Convertible.

The fourth generation of BMW's open-topped M3, the car will become the first M model to feature a retractable hard-top.

The vehicle will also be the first to include the German manufacturer's new seven-speed M double-clutch transmission (M DCT) as an option to the standard six-speed manual gearbox.

Originally launched in 1988, the M3 delivered 200hp from BMW's first 16-valve 2.3-litre four-cylinder engine.

Fast forward to today and the new M3 breaks through the 100hp per litre barrier once again - offering 105hp per litre.

The new car also offers a ten per cent improvement in the power-to-weight ratio when compared to its predecessor E46 M3 Convertible.

The V8 engine powers the car from zero to 62mph in 5.3 seconds and on to an electronically-limited top speed of 155mph.
