Engineering the 7-series hybrid, BMW found ways to drastically increase the overall power, compared to the 750i, which uses the same gasoline engine. At the same time, this 7 gets the best fuel economy among its 7-series siblings.
The engine is a twin turbo direct-injection 4.4-liter V-8. With its hybrid system, made up of a lithium ion battery pack and electric motor, total power output is 455 horsepower and 515 pound-feet of torque.
Trunk space is impinged by the lithium ion battery pack, which is oddly packaged. Other automakers tend to integrate battery packs into the trunk walls, but BMW just leaves the big, cubic pack sitting out.
The shifter controls an eight-speed automatic transmission, which helps this car get highway fuel economy of 26 mpg. A rocker switch to the left of the shifter sets the suspension to comfort or sport modes.
