There is a big difference in weight between the coupe (which has a roof of carbon fiber) and this convertible. The retractable hardtop, the mechanisms that move and reinforcements needed in the structure of the car cause the weight of BMW M3 Convertible reaches 1,885 kg, 230 more than the coupe.

Due to this increase in weight and that of the aerodynamic drag it might have, benefits and consumption of convertible differ from those of the coupe. The only thing that remains unchanged is the maximum speed, which is limited to 250 km / h in both cases.

There are not many convertibles four places in this power level. The BMW 650i and Jaguar XKR Convertible are convertibles luxury, more costly and less cumbersome. The Audi RS4 is closer to that effect in this version of BMW M3 Convertible.

Like the other versions of Series 3, BMW M3 Convertible has a retractable hardtop in three pieces; it takes 22 s to open. Its operation is completely automatic and electricity has no additional closure that has to manage manually. In addition, the roof can be manipulated from the remote control.

The engine of BMW M3 Convertible is atmospheric, eight cylinders in V, 4.0 litre engine capacity and 420 hp. From what we've seen in the coupe version, is an engine that requires quick turn carry over 6,000 rpm to give the response is expected of a car of this power.

Despite this, we can move in a jam at 1,000 rpm in second gear without giving hitches or make strange noises. Its consumption is high.

The gearbox is a six-speed manual. The developments of transmission are the same as in the coupe. It may be the new automatic gearbox Drive logic seven speeds, increasing the acceleration and reduces consumption.

As in the coupe, there are several optional elements that affect driving. The M Drive allows varying the throttle response and the degree of assistance from the leadership. If the car carries the option of variable damping (EDC), also can be changed with the M Drive.

The stability control (DSC) can be switched off completely or partially in a manner that does not preclude a certain slippage before being put into operation.
