- System output of 260 kW and peak torque of 500 Newton metres
As BMW continues to push ahead with the development of intelligent hybrid drive systems, the second generation of the BMW ActiveHybrid 7 is celebrating its premiere this year. The updated model sets itself apart with lower fuel consumption and emissions, as well as innovative auxiliary functions.
This latest evolution stage uses a BMW TwinTurbo six-cylinder in-line petrol engine displaying impressive high-revving characteristics, torque and efficiency. The cutting-edge petrol engine with BMW TwinPower Turbo technology is the 235 kW variant of the unit fitted in the new BMW 740i and replaces the eight-cylinder engine used up to now.
Other hybrid components include the 40 kW synchronous electric motor, the hybrid-spec eight-speed automatic transmission, a lithium-ion high-performance battery and power electronics underpinning intelligent energy management. The various components come together into a powerful and harmonious whole, giving the new BMW ActiveHybrid 7 exceptional dynamics and an outstanding balance between performance and fuel economy – and not only in relation to its predecessor.
With system output of 260 kW and peak torque of 500 Newton metres, the new BMW ActiveHybrid 7 accelerates from 0 to 100 km/h in just 5.7 seconds. At the same time, the Sedan posts average fuel economy of 6.8 litres per 100 kilometres and CO2 emissions of 158 g/km. That means the more powerful hybrid technology uses some 14 per cent less fuel than a BMW 740i with a conventional drive system.
A host of innovative functions are involved in enhancing the car’s dynamics and achieving the excellent efficiency of the overall system. For example, the electric motor hands the six-cylinder an extra 210 Newton metres of torque through the boost function, should the driver need to nail a quick sprint or call on some hard mid-range acceleration. In addition, Brake Energy Regeneration, the Hybrid Start Stop function, ECO PRO mode with coasting function and proactive analysis – to prepare the car’s drive system in advance for upcoming situations on the road – ensure the available energy is used as efficiently as possible (more details in the “BMW EfficientDynamics” chapter).
The new BMW ActiveHybrid 7 can also run purely on electric power. If the hybrid battery has sufficient charge and the driver goes easy on the accelerator, the car can cover a distance of up to four kilometres almost silently and without producing any tailpipe emissions. The top speed possible using electric power alone is 60 km/h.
The BMW ActiveHybrid 7 is also produced at BMW Plant Dingolfing – the BMW Group’s largest production plant worldwide. The plant also handles production of the BMW 6 Series and BMW 7 Series, including the BMW ActiveHybrid 5.
The BMW plant in Dingolfing, Lower Bavaria, has been part of the company’s global production network since 1967. Today this network comprises 25 plants in 14 countries across five continents. 1973 saw the start of BMW vehicle production at the newly constructed Plant 2.4 in Dingolfing. Approximately 18,600 people currently work at the site, more than 12,000 of them in car production at Plant 2.4.
