Derived from the potent 5.0L V10 engines used in the larger M5 and M6, the new V8 unit will displace 4.0L and produce its peak 420hp output at a lofty 8,300rpm, while maximum torque of 400Nm comes in at even higher 8,400rpm. Though this latter figure might not seem so impressive, 85% of twist will come from just 2,000rpm. This means the new bahn-stormer will have an almost flat torque and a power band stretching almost 6,500rpm. First sales will be for the coupe model, which is expected to start in September this year, followed by the convertible, sedan and touring variants soon after.
