The new M3 redefines sports coupe, and now sports convertible, making it a natural progression for BMW to introduce a second-generation "sequential M gearbox" (SMG II). Working with Getrag and Sachs, BMW has fitted F1-style shift buttons to the steering wheel, with the transmission ready to work in automatic or sequential mode. With the driver's foot standing on the accelerator, the system can shift in a mere 80 milliseconds. The setup uses numerous s goensors to ensure the best, appropriate shift and it teams with the traction systems for optimum performance.
