BMW typically underates the power in their vehicles. The M5 has been quoted as low as 2.8 seconds to 60, and many of the vehicles have more horsepower than what BMW puts on paper. Also, there will be an X7 M50i in a year replacing the X7 50i which will have 500+ hp and more torque, as the engine from the 8 series is making its way into other vehicles.
