Pricing will be announced closer to the on-sale date.
The X5 xDrive40e is expected to have an all-electric range of about 15 miles, according to BMW spokesman Dave Buchko. He could not provide U.S. fuel economy numbers at this point.
The EPA has not yet rated the X5 xDrive40e.
Buchko said the X5 xDrive40e is not tied to BMW's i Brand. Because of that, the crossover will be available at all U.S. BMW dealers.
The key competitors to the X5 xDrive40e are the Porsche Cayenne S E-Hybrid and the Cayenne Diesel. But Buchko said the newest X5 also competes with "luxury SUVs in general." They include the Audi Q7, Land Rover Range Rover Sport and Mercedes-Benz M-Class.
This is the first plug-in hybrid production car from BMW's core brand, the automaker noted.
"Our research has indicated that vehicles like the X5 don't tend to make long trips on a regular basis," Buchko said. "They're a family car for around town. The average drive time could be spent on electric power alone."
The X5 xDrive40e's powertrain includes a turbocharged 2.0-liter four-cylinder gas engine, an electric motor, a lithium-ion battery and an eight-speed Steptronic transmission. Total system output is 313 horsepower.
BMW said the X5 xDrive40e sprints from zero to 62 mph in 6.8 seconds.
The battery is housed underneath the luggage compartment floor to save space.
U.S. details on the X5 xDrive40e are expected to be announced shortly.
Edmunds says: Luxury shoppers searching for a family-friendly alt-fuel vehicle undoubtedly will put this latest version of the X5 on their shopping lists.
