M TwinPower Turbo.
World première: as soon as you start the highly efficient engine, it becomes unmistakably clear that the first M TwinPower Turbo with 555 hp is not just impressive on paper. It’s 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 500 lb-ft that remains constant over an extremely wide rev range, from 1,500 to 5,650 rpm, this is an astonishingly potent machine.
