BMW ACTIVEHYBRID 7 A NEW LEVEL OF EFFICIENCY

The next generation of the ActiveHybrid 7 is here with more power and lower fuel consumption thanks to its 3.0-liter TwinPower Turbo inline 6-cylinder 315 hp engine paired with a 55 horsepower electric motor. With its hybrid-spec 8-speed Steptronic automatic transmission and a 0-60 time of 5.6 seconds; this hybrid feels like its part luxury sedan and part racecar.

As its name suggests, the ActiveHybrid 7 is a gas-electric version of BMW's 7-Series full-size luxury sedan. It's spacious and opulent, but a high price and unimpressive fuel economy make it tough to recommend.
Notably, the ActiveHybrid 7 is available in long-wheelbase form only, stretching 5.5 inches longer in wheelbase and overall length than the standard 7-Series.
Recent Changes
The ActiveHybrid 7 benefits from a host of new standard equipment for the latest model year, including remote services, BMW Apps, real-time traffic information, BMW Assist eCall, BMW Online, BMW TeleServices and a dynamic instrument cluster. Additionally, the iDrive infotainment system now features a touchpad for "writing" numbers and letters for tasks like entering navigation destinations or saving phone numbers.
Last year, the ActiveHybrid 7 received freshened styling inside and out along with a thorough hybrid powertrain rethink that saw the replacement of the previous, V8-based setup with the current, more efficient six-cylinder arrangement.

Overview
The ActiveHybrid 7 is based on the 740Li, with both sedans featuring a turbocharged 3.0-liter inline-six. The ActiveHybrid 7 goes a step further by adding an electric motor electric motor housed within the car's eight-speed automatic transmission that essentially takes the place of the torque converter. Total system output is rated at 349 horsepower and 367 lb-ft of torque.
Those figures that represent noticable gains over the 740Li's 315 ponies and 330 lb-ft, but the extra weight of the ActiveHybrid 7's electric motor and battery pack effectively negates any acceleration advantage. The ActiveHybrid 7 also offers little in the way of a fuel economy advantage, returning 22/30 mpg to the less expensive 740Li's 19/29 mpg.
Like most other hybrid vehicles, the ActiveHybrid 7's gas and electric engines are capable of operating independently or together. Given a light enough right foot, the car can be coaxed into covering 2.5 miles using only the electric motor. The top speed on electric power alone is 37 mph.
Green Tech Barrage: Driving Dynamics Control, Eco Pro and Coasting Modes
The ActiveHybrid 7 features a Driving Dynamics Control system that allows the driver to personalize a wide-range of the car's systems to suite his or her tastes, including accelerator response, engine response, power steering characteristics, stability control thresholds, transmission and damper settings and more.
Drivings Dynamics Control offers five pre-set settings, with Eco Pro being the most notable. Eco Pro optimizes a host of vehicle elements, such as the powertrain and programming of the heating and air conditioning, heated seats and exterior mirror heating, to operate with maximum efficiency. When used in conjunction with an efficient driving style (which the system actually offers tips for), Eco Pro can help reduce fuel consumption by up to 20 percent, BMW says.
Eco Pro also features a coasting mode that decouples the engine when coasting at speeds between 30-100 mph. The ActiveHybrid 7 gets a unique coasting mode that shuts off the gas engine when coasting, letting the car glide along sans emissions.
