The M4 is the newest addition to BMW's line of notorious M performance coupes. Power comes from a 316 Kw twin-turbocharged in-line six-cylinder engine, mated to either six-speed manual or a paddle-shifted seven-speed automatic transmission and rear-wheel drive and drivers can expect explosive performance from the M4's new engine, as well as the M Division's renowned handling capabilities In a mission to shave weight, many of the M4's components are now made of carbon fibre (and this includes the driveshaft). Based on the current, F30-generation 3- and F32 4-series, the new M4 is longer and wider than its M3 predecessor and much lighter. Extremist enthusiasts applaud BMW's fanatical approach to weight saving, and on this generation, BMW fashions the front and rear suspension links, as well as the hood and fenders, from aluminium. Carbon fibre is used for the roof, drive-shaft (as already mentioned above) as well as the boot-lid. One of the worst things a carmaker can do is succeed. When buyers love your car, they don't want it to ever change. Any changes can mean a backlash from your ardent supporters/owners. BMW M fans got a double shot of hard-to-swallow change when the brand announced the next generation - the M3. The coupe, the original and most iconic M3 body style, was upgraded to the M4 (but still maintaining the M3) By all measurements, the M4 is a legitimate successor to the M3 in its driving dynamics, performance, engineering and efficiency. For those obsessed with numbers, BMW says this M4 coupe will lap the famed Nurburgring Nordschleife a full 15 seconds quicker than its predecessor (and five seconds quicker than the current M5). More importantly is that BMW has not altered the M3's long-celebrated recipe with the arrival of the M4 – the new model debuts as a brilliantly uncompromising two-door sport coupe that is equally capable on the road as it is on a race-track.
