We call the BMW M5 Touring powerful, but is it? Is it really? In 2026, is 717-horsepower from a twin-turbo V8 and electric motor really enough to make this a powerful car when you can beat that by slapping a $10,000 supercharger onto your beat-up F-150? German performance tuner Manhart feels very strongly that it isn’t enough, and it hopes that potential M5 buyers will feel the same way. It has just launched its solution, in the form of the 898 hp Manhart MH5 900E.
