BMW ’s quest for efficient engines goes to the BMW 132 aircraft engine of the 1930s.  recently, for the 1972 Olympic in Munich. BMW provided a fleet of BMW 1602 sedans that a battery-powered electric motor.

A few ago we reviewed the world’s fastest hybrid, the BMW ActiveHybrid X6. and that has now passed to the BMW ActiveHybrid 7.  This may like an odd title for a hybrid as we found out in our tests, it proves one can fun and enjoy better fuel at the same time.

The previous of the BMW 7er Series (the 7er Series was all new for year 2009) was available in a duel-fuel hydrogen powered and the engineers at the company were at work to create additional, options for their customers.

Enter the ActiveHybrid 7.  Unlike the X6, which is a full hybrid has an electric-only means of propulsion, the 7 is a mild hybrid, an approach adds less weight and (and cost) to the vehicle.  The platform was jointly developed by BMW and -Benz as an outgrowth of a cooperation began in 2005 and Mercedes the same platform in the S400 we reviewed last month.

A hybrid is a gasoline-fueled vehicle with an electric motor allows the engine to be automatically off whenever the car is braking, coasting, or A mild hybrid also brake energy regeneration to energy that would be wasted as heat through the The integrated electric motor as a generator when coasting or the brakes and feeds electric into the battery.    As a result, do not require the same level of power and also do not achieve the increase in fuel economy as hybrids .

The ActiveHybrid 7 has an upgraded twin-turbo injection V-8 engine with a synchronous electric motor, it a combined output of 455 hp and maximum of 151 pound-feet.  The electric motor is between the engine and the torque and power is transmitted via a new eight-speed

It also has almost the same of luggage space as the gasoline-only as the 120-volt battery occupies one cubic foot.

When the accelerates, electricity (from the is fed back into the on-board network and provides power to the rear wheels, relieving the engine from this

All this translates into mph in just 4.7 seconds with 15% fuel economy than the 750i.

The ActiveHybrid 7’s transmission start-stop technology to avoid idling when stopped, other systems such as air remain operational as power is through the lithium-ion battery.  to the ActiveHybrid X6, it is equipped with Aero wheels that drag.

  A bar that shows the current over the past fifteen is also available.

In terms of the high-voltage system is fully and the battery is protected by a steel In the event of a collision, the entire system is immediately switched

After all this, you may wonder how the 7 drives.  I spent a week the ActiveHybrid 7, driving it on twisty roads, highways, and city and I was hard-pressed to tell the difference it and the V-12 powered 760Li hitting the accelerator.  The start-stop is reasonably inconspicuous although a move from brake to gas can in a bit of a jerk.

  Thanks to the tiny and mild hybrid system, the weight distribution was preserved, bodes well for handling is one of the reasons BMW uses different systems in the X6 versus the 7er).

The and responsive ride was adjustable via the driver-selectable settings in the Driving Control system.  Set for sport, the 7 attacked twisties with a On some pot-holed New York streets, I didn’t notice the go by.

The fuel economy I got during week, however, served as an reminder that I was, in a hybrid vehicle.  It consistently got 3 mpg than the 750i in city averaging 20 mpg.  My overall economy for the week was 24.5

Best of all, the ActiveHybrid 7 for a $900 IRS Alternative Motor Credit.
