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.
