M3 Concept
A maximum torque of 400 Newton meters at 3,900 RPM is reached. Approx. 85 percent (340 Nm) can be utilized beyond the enormous engine speed range of 6,500 RPM.
The S65B40 attains 8,400 RPM, and therefore a value that was previously only reserved for racing car engines or exotic custom vehicles.
For safety reasons, due to the engine dynamics when the vehicle is stationary (i.e. without a road-speed signal), it is already down-controlled at 7,000 RPM to prevent the engine speed from increasing into an impermissible range.
