The M TwinPower Turbo in the BMW X5 M.

World premiere: as soon as you start the highly efficient EU5 engine, it becomes unmistakably clear that the first M TwinPower Turbo with 555 hp is not just impressive on paper. Its more than 126 hp per litre output sets standards while the patented cross-bank exhaust manifold and two Twin Scroll turbochargers guarantee maximum power flow and optimum transfer of exhaust gas energy to the turbocharger rotors. As a result, the M TwinPower Turbo unit boasts faster turbocharger response than any other Turbo engine in the world. With high torque of 680 Nm that remains constant over an extremely wide rev range, from 1,500 to 5,650 rpm, this is an astonishingly potent machine.
