2013 BMW M5

According to Car and Driver, citing a report in BMW Blog, BMW will be offering performance upgrades – likely called the Competition package – for its M5 and M6 models (including the convertible and Gran Coupe versions of the M6). Both cars will continue to be offered with the normal 560-horsepower, 4.4-liter twin-turbocharged V8 engines, but this new performance pack is expected to add an additional 15 hp to the mix.

No need to worry, however – the upgrades won't simply be limited to a small boost in power. These M5 and M6 models will reportedly get new wheels, black exhaust tips, a more direct steering ratio and reworked suspension geometry which will provide better overall handling. Top speed is said to remain governed at 190 miles per hour, but that these extra improvements will shave one-tenth of a second off the cars' 0-60 times.

No pricing information has been revealed as of this writing, though we imagine it'll likely come at a substantial cost over the current starting prices of the M5 and M6 ($90,200 and $108,350, respectively).
