According to sources, the BMW 540e will be equipped with a gasoline engine four-cylinder TwinPower turbo producing 258 hp and 400 Nm of torque featuring a VALVETRONIC valve control, control double overhead camshaft VANOS and “High Precision Injection” direct injection, together with an electric motor of 95 hp for a total power of 326 hp.
The electric motor generates a torque of 250 Nm and is water cooled. The battery is located under the rear seats and while driving, the electric motor can be recharged by the alternator function, transforming the kinetic energy into electrical energ during moments of inertia or during braking.
By setting a route, depending on the navigation data to access the vehicle, the hybrid system can foresee strategically and analyze the roads ahead in real time and traffic conditions. The system will also choose the best time to use the electric motor, or perform the battery charging or move in hybrid mode.
The system is coupled to the 8-speed automatic transmission which can reduce fuel consumption below 2.1 liter per 100 km. The BMW 540e can travel up 30 km in purely electric mode with a maximum speed of 120 km/h.
Unlike the 530E, the 540e may be equipped with xDrive all-wheel drive and also offer induction charging.
BMW will unveil the G30 5 Series next year, followed by the 540e in 2017.
