The plug-in hybrid version of BMW’s midsize premium SUV arrived for the U.S. market in the fall of 2015 as the first plug-in hybrid from the German brand. At the heart of the X5 xDrive40e is BMW’s 2.0-liter TwinPower Turbo 4-cylinder engine teamed with an electric motor integrated into the 8-speed automatic transmission, for a total system output of 308 horsepower and 332 lb-ft of torque. Intelligent all-wheel drive is standard. On a full charge the lithium-ion battery offers an electric-only range of 14 miles and can propel the plug-in X5 from zero to 60 mph in 6.5 seconds.
