BMW 535i GT - New Single Turbo VALVETRONIC N55 Engine

German specialists from BMW have developed the TwinPower Turbo, High-Precision Injection VALVETRONIC, straight-six gasoline engine. This new unit will power the BMW 535i Gran Turismo and it is part of the process of optimizing engine power while at the same time reducing both fuel consumption and CO2 emission levels an engine of this caliber. The 3.0-liter engine is part of the EfficientDynamics development strategy and it offers a range of highlights in technology never seen on any other engine. The unit combines turbo-charging, direct gasoline injection and fully variable VALVETRONIC valve management developed by BMW. The result exceeds even the response and efficiency of the BMW Twin Turbo power unit launched back in 2006. The biggest advantage of the ALVETRONIC is the infinite control and adjustment of valve stroke on the intake valves. It reduces throttle losses in the charge cycle process to an absolute minimum and optimizes engine response since the air mass required to control the combustion process is masterminded in the engine itself and not outside the power unit with the usual volume. This is actually a good thing as it assures efficient use of the energy contained in the fuel, developing a very muscular torque curve and giving the engine optimum response. When it comes to the BMW 535i Gran Turismo, the ALVETRONIC functions have been optimized again by a new adjuster complete with a fully integrated sensor. This helps improve the adjustment process. The new straight-six is clearly the leader in its class also in this discipline. It can produce a maximum torque of 400 Nm. The new turbocharger also contributes to this superiority, ensuring a particularly spontaneous build-up of power since the ducts of 3-cylinders at a time are separated from one another both in the exhaust manifold and the turbocharger.
