BMW Introduces Three 7-Series Plug-in Hybrids
BMW introduced three 7 Series plug-in hybrid luxury sedans with latest-generation gasoline engine and electric motor combinations.
The BMW 740e iPerformance, 740Le iPerformance, and 740Le xDrive iPerformance are three renditions of the same powertrain technology inside the flagship 7 Series sedan lineup. The 740e is the standard wheelbase and the 740Le are the long-wheelbase versions of the sedan. The xDrive moniker denotes that that particular model is all-wheel drive.
A four-cylinder turbocharged gasoline engine and electric drivetrain combine to give a total system output of 326 horsepower (240 kW). Fuel consumption in the two-wheel drive models is rated at 106.8-117.5 mpg combined (per BMW). The AWD model (xDrive) is BMW-rated at 94-111.9 mpg. EPA fuel economy testing has not been undertaken as of this writing.
The 7 Series plugins will have a maximum electric range of about 25-30 miles per charge, depending on model. The engine in the new 7 Series is the most powerful 2.0-liter four-cylinder BMW has ever fitted to a series production vehicle, outputting 258 hp with BMW's TwinPower Turbo technology. The motor used has a maximum output of 113 hp (83 kW). It also acts as a generator when braking, with the help of the eight-speed Steptronic transmission.
And so ...
Hybrid functions in the new 740e vehicles will be much the same as that found in the BMW X5 plug-in hybrid, which will be reviewed here on FutureCars soon.
