New BMW ActiveHybrid 7: Inline 6-cylinder engine combined with full-hybrid power.

As BMW continues the development of intelligent hybrid drive systems, the second generation of the BMW ActiveHybrid 7 is set to take a significant step forward for the 2013 model year. The updated model sets itself apart with lower fuel consumption and emissions, as well as innovative auxiliary functions. This latest evolutionary step uses BMW's 3.0-liter TwinPower Turbo inline 6-cylinder engine. In this application it is the same 315 hp version as in the new BMW 740Li and replaces the V8 engine previously used in the ActiveHybrid 7. Other hybrid components include a 55 hp synchronous electric motor, hybrid-spec 8-speed Steptronic automatic transmission, a lithium ion high-performance battery and power electronics which run the intelligent energy management. The various components create a powerful and harmonious whole, giving the new BMW ActiveHybrid 7 an outstanding balance between performance and efficiency. With combined output of 349 horsepower and peak torque of 367 lb-ft, the new BMW ActiveHybrid 7 accelerates from 0 to 60 mph in about 5.6 seconds (preliminary). At the same time, it delivers significantly improved fuel efficiency. US EPA numbers are not yet available. However, in the EU test cycle the new ActiveHybrid 7 yields efficiency gains of 14 percent over the new 740Li which is an impressive improvement over its predecessor.

A host of innovative features enhance the car's dynamics and ensure optimum efficiency of the hybrid drive system. For example, the electric motor provides an extra 155 lb-ft of torque through the boost function if the driver should need a quick sprint or to call on strong mid-range acceleration, when passing or merging for example. ECO PRO mode, with coasting function and proactive analysis, prepares the drive system in advance for upcoming situations on the road. Brake Energy Regeneration and the Hybrid Start-Stop system also work together to maximize overall efficiency.

The 2013 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 2.5 miles almost silently and without producing any tailpipe emissions. The top speed on electric power alone is 37 mph. The new ActiveHybrid 7 will be available in the US as a long-wheelbase model only.
