BMW debuts another 7 Series model at the 2015 Frankfurt Auto Show. Set to compete with the Mercedes-Benz S550 Plug-In Hybrid, the 740Le xDrive will use advanced technologies learned from BMW’s newfound experience.

The 740e xDrive will employ similar techniques found in the i8 and its integration of gas engine, Steptronic transmission and electric drive unit. The 740e xDrive will use a similar setup to the X5 xDrive40e, a 2.0 liter TwinPower turbocharged four-cylinder engine paired to an electric motor and eight-speed Steptronic transmission which will send power through all of the wheels via BMW’s latest xDrive all-wheel drive system. The electric motor will be powered by a Lithium-Ion Battery, located under the rear seat for better weight distribution and crash protection, which can be recharged via any domestic power socket, BMW i Wallbox or public charging station.

The 740e xDrive will utilize an eDrive button on the center console to control the level of electric drive being utilized. There will be three settings, AUTO eDrive, MAX eDrive and Battery Control modes. AUTO eDrive will be the basic setting, using the electric motor to maximize engine power when needed, such as during hard acceleration. MAX eDrive allows the 740e xDrive to drive purely under electric power, at up to 75 mph, for 23 miles.

That’s three more miles than the S550 Plug-In Hybrid, though the Benz can do up to 87 mph under pure electric power. Battery Control Mode maintains or raises the battery’s state of charge so as to conserve power. It will also utilize the navigation system and route guidance to create a trip-specific strategy to conserve energy necessary for the destination. The eight-speed automatic’s Brake Energy Regeneration and Route-Ahead Assistant systems will also aid the car in seeking out extra mileage for the battery.
