A review of a BMW M4 3.0 BiTurbo DCT Coupe by Invictus Motors. BMW M4 is a brilliant performance car and one that meets all the targets BMW set for it when it morphed from the fourth-generation M3 Coupe of 2007-2013. BMW wanted its legendary motor to have more torque, more power, less weight, and even better performance – and, on all counts, the M4 has delivered on the promises. The M4 remains one of the greatest all-round performance coupes you can possibly buy.
