2013 BMW M5

We were grateful that the F10 M5 came with a manual, and probably as surprised as most that BMW elected to only sell them in the US. This example has been lightly modified with top-shelf parts including an upgraded intake to give the turbos more air to force into the motor, along with a freer flowing exhaust system to reduce pumping losses. Taken together, we are confident that this M5 produces a fair bit more than the 560HP that came from the factory.
