A tuned version of the BMW M5 is being offered, with some outlets reporting it has around 900 horsepower, while others mention a figure of 1,000 horsepower. The upgrade, which may be called the G5M Hurricane RR, is said to cost €115,000. However, there is some uncertainty about the specifics of the vehicle, including its exact horsepower and whether it is based on the M5 or another model.
