Journalists around the world have been lucky enough to enjoy both the 2014 BMW M3 and M4 sports cars at the famous Spa-Francorchamps. The following video showcases expert driver Ron Simons from RSR Racing in a Sakhir Orange BMW M3 chasing a Mineral White M4 throughout the exciting lap!

Under the hood, both the new M3 sedan and M4 coupe are of course fitted with a twin-turbocharged six-cylinder engine revving to 7,600 rpm and producing an impressive 431 hp between 5,390 rpm and 7,000 rpm and 406 lb-ft of torque from a low 1,800 rpm to 5,390rpm. That torque figure is available across a broad rev range and is an improvement over the outgoing BMW E92 M3 of 40 per cent.
In addition to this increase in power and torque, both new models weigh around 80 kg less than a comparably equipped predecessor model. As a result, the BMW M4 Coupe tips the scales at 1,497 kg while the M3 Sedan stands at 1,520 kg in base specification. These weight savings have been achieved through the extensive use of carbon fiber reinforced plastic as well as a carbon fiber roof and aluminium chassis and body components.
