The German automaker is keeping interest alive for the M4 via the official introduction of the all-new M4 CS, featured in between the standard M4 with the Competition Package and the hardcore, limited series, sold-out track oriented M4 GTS.
BMW says the new CS is here to stay as the flagship version, as a version sitting above the versions featuring the Competition Package. The most important upgrade has to do with the 3.0-liter engine, which has been tweaked for an extra 10 horsepower and 37 pound-feet (50 Newton-meters) of torque compared to the M4 carrying the Competition Package. This enables the biturbo straight-six to reach 460 hp and 442 lb-ft (600 Nm), with the M4 CS sprinting to 62 mph (100 kph) in only 3.9 seconds (down by a tenth of a second), while maximum speed is an electronically-governed 174 mph (280 kph).
The only transmission option is a seven-speed, double clutch automatic transmission, and the M4 CS has also undergone a diet to further enhance its status. The weight-saving measures have dropped 32 kilograms (70 pounds) compared to the regular DCT version, thanks to carbon fiber-reinforced plastic (CFRP) elements such as the roof or hood. Inside the maker used compacted natural fibers for the door panels and the side trim in the rear compartment, lightweight loops, and a single-zone climate control system and bespoke audio system. The final touches come from the revised suspension and new lightweight 19-inch front / 20-inch rear wheels.
