Duncan Forrester, of BMW, said: “We set out with the Z4 to bring the engine noise back into the cabin. With a car like this, it is essential that the driver can hear the engine, what it is doing, and what is going on under the bonnet.”
BMW boasts of having 100 “acoustic engineers” on its books. Their work means that the BMW 7 Series saloon whispers along in a vacuum, the driver worried about having gone deaf. At traffic lights, only a furtive glance at the rev counter tells you that the engine hasn’t died. By contrast, the Z4 is motor-din heaven. Like a decent audio system, the car’s engine sound management system has been tuned to get the most out of the motor. Noise from the engine is fed into the cabin, with intake system pressure noises from the intake manifold, instead of being killed off with yards of felt matting. It arrives in the cabin via a tube and a flexing diaphragm. The result is a high-octane backing track.
