2011 BMW ActiveHybrid 7 Edition


BMW’s hybrid system adds significant power to the ActiveHybrid July 2011, to make it the most fuel-efficient model in the series 7. An active suspension gives the car excellent handling. Google Local Search is integrated with the navigation system.

The bad: Points of interest and music library screens are intuitive and not easy to operate while driving. The functionality of the hybrid system idle stop off and no power steering works well in stop-and-go traffic.

The bottom line: Despite the power of technology in some aspects, the hybrid system in 2011, the BMW ActiveHybrid 7 seems a novelty. He adds energy and energy efficiency, but also adds tricks everyday driving. features cutting-edge cabin technology available on all models of 7 series.

Most manufacturers use the additional energy provided by a hybrid system to go out with a small gasoline engine, thereby maintaining the power expected, but reduce fuel use. BMW looked for that extra energy and thought, “Excellent, we can make our cars faster!” Such is the case with BMW ActiveHybrid July 2011, which hosts the same engine as the BMW 750i standard, a twin turbo direct injection 4.4-liter V-8, but straps on an electric motor receiving power from a lithium ion battery of 120 volt battery. The result: more power and better fuel economy than the 750i.

Besides the powertrain, the ActiveHybrid 7 offers all the amenities of a typical 7 series. In fact, BMW makes many features standard on the hybrid technology that would be options on other models of 7 series. Things like the system update 16-speaker audio, head-up display and rear view camera comes with the car, helping to justify its price premium, high even by the standards of BMW.


Mild hybrid

As the ActiveHybrid 7 of the hybrid system can not drive the car fully in power, should be considered a mild hybrid system. As the integrated Honda Motor Assist hybrid system from BMW adds momentum in acceleration and allows the engine off at traffic lights. But ActiveHybrid 7 seems much smoother.

From the driver’s seat, just indicate the hybrid system. As in other new BMWs, the tachometer has a blue region in the fuel economy indicator, indicating when the car is regenerating electricity from its dynamics. The center superwide 10.2 inch LCD can be done to show a real-time animation of the energy distribution of the hybrid car, but its 3D presentation makes it harder to read than the diagrams of power found in hybrids from Toyota and Ford.

The clearest indication of the hybrid nature of the car comes when he stops at a stoplight. The tach needle drops to zero as the engine is silent. Take your foot off the brake and motor back to life with amazing smoothness, considering the size of the engine.

This system of automatic idling stop requires some getting used to, and is not preferable in some situations. Works great on sites with particularly long traffic lights, as the car can not sit there burning gas or pump out pollutants and carbon dioxide. But in traffic jams, with stop-and-go traffic, shutting down the engine for 5 seconds at a time is not as efficient, and is slightly irritating to the driver.

The amount of energy on tap at 7 ActiveHybrid also takes some getting used to because the car lunges forward with just a light touch on the accelerator. Put a label on a hybrid car may sound green, but the real strength of this hybrid system is power. The combined output of the turbo V-8 and the electric motor is rated at 455 horsepower and 515 pound-feet of torque. Compare that with 400 horsepower and 450 pound-feet of torque on a 750i. The 7 ActiveHybrid power is closer to the V-12 760i.

BMW ActiveHybrid 7 puts the acceleration in 4.7 seconds at 60 mph, and feels every bit as fast when you put the pedal to the metal, or the pedal to the carpeted floor plushly. The car comes on, quickly adjusting the traction control supply to maintain the useful movement of the tire, making very little hesitation the initial impulse. The big car feels stable and solid as it gains speed, the speedometer 60 MPH slip to hit 70, 80 and 90 in quick succession.
