BMW Unveils the All-new Plug-in Flagship
The BMW eDrive drive system technology developed for BMW i cars has arrived in the new BMW 7 Series model range in the shape of three plug-in hybrid luxury sedans. The trio source their power from the myriad talents of a latest-generation four-cylinder petrol engine with BMW TwinPower Turbo technology and an electric motor.
Together, they deliver a system output of 240 kW/326 hp. The new BMW 740e iPerformance with standard wheelbase and the new BMW 740Le iPerformance with long wheelbase capture the imagination with supreme dynamics, yet also record average petrol consumption of 2.2 – 2.0 litres per 100 kilometres / 128.4 – 141.2 mpg imp and CO2 emissions of 50 – 45 grams per kilometre (BMW 740Le iPerformance: 51 – 45 g/km). In the new BMW 740Le xDrive iPerformance (petrol consumption combined:
2.5 – 2.1 l/100 km [113 – 134.5 mpg imp]; CO2 emissions combined: 56 –49 g/km), intelligent all-wheel drive distributes the combined power of the combustion engine and electric motor permanently and as required between the front and rear wheels. The maximum electric range, as per the EU test cycle for plug-in hybrid vehicles, is 44 – 48 kilometres / 27 – 30 miles for the BMW 740e iPerformance and BMW 740Le iPerformance, or 41 – 45 kilometres / 25 – 28 miles for the BMW 740Le xDrive iPerformance (figures may vary depending on the tyre format specified).
The combustion engine with BMW TwinPower Turbo technology employed by the plug-in hybrid variants of the new BMW 7 Series is a member of the new Efficient Dynamics engine family. Developing maximum output of 190 kW/258 hp, it is the most powerful four-cylinder engine ever fitted in a series-produced BMW. Instantaneous power delivery and peak torque of 400 Newton metres (295 lb-ft) – on tap across a wide rev range (1,550 – 4,400 rpm) – imbue the 2.0-litre unit with vivaciously sporty yet also poised and authoritative performance. In addition, the new engine displays outstanding refinement. The electric drive system, based on the principle of a permanently excited synchronous motor, boasts exceptionally high power density with a maximum output of 83 kW/113 hp. As is characteristic for electric drive systems, it serves up its peak torque of 250 Newton metres (184 lb-ft) from the word go. The boost effect for the combustion engine provides the driver with thrillingly instantaneous responses. Furthermore, the electric motor takes on the role of a generator which – depending on the hybrid function selected – is powered either by recuperating braking energy or by efficiently raising the engine’s load points. It then feeds the energy it generates into the high-voltage battery. The electric motor is fully integrated into the eight-speed Steptronic transmission. This ensures that pure-electric driving, the dynamics-enhancing electric boost function and the recuperation of braking energy are all extremely efficient. The eight-speed Steptronic transmission has outstanding internal efficiency, top-class shift dynamics and shift comfort, and a compact construction. Gearshift paddles on the steering wheel are available as an option, enabling the driver to make manual gear selections with exceptional swiftness and the greatest of ease.
Working together intelligently, the combustion engine and electric drive system bring a system output of 240 kW/326 hp and a combined peak torque of 500 Newton metres (369 lb-ft) to the table. Immediate response to every movement of the accelerator and sustained delivery of dynamic power allow the BMW 740e iPerformance to dash from 0 to 100 km/h (62 mph) in 5.4 seconds and the BMW 740Le iPerformance to complete the same sprint in 5.5 seconds.http://pluginfuture.com/bmw-unveils-the-all-new-plug-in-flagship/http://pluginfuture.com/wp-content/uploads/2016/07/BMW_2-1024x519.jpghttp://pluginfuture.com/wp-content/uploads/2016/07/BMW_2-150x150.jpgNewsVehiclesplug-in limousine,plug-in vehicleThe BMW eDrive drive system technology developed for BMW i cars has arrived in the new BMW 7 Series model range in the shape of three plug-in hybrid luxury sedans.
