An undisguised prototype of the BMW X5 eDrive was photographed ahead of this year's market launch.

BMW recently updated the X5 eDrive concept and now a prototype wearing the production body was spotted testing in China featuring a slightly different front bumper which probably offers increased aerodynamic efficiency. Another obvious change is the addition of the plug-in charger on the front-left fender while the rest of the car appears to be identical, with the exception of the covered "eDrive" badge at the back.

The production car will reportedly receive the "xDrive40e" designation and will probably have the same technical specs as the concept so expect a 4-cylinder 2.0-liter turbocharged gasoline engine working with an electric motor and a lithium-ion battery mounted underneath the trunk. The regular engine puts out 245 PS and 350 Nm while the electric motor generates 95 PS and 250 Nm to provide a combined output of 340 PS (250 kW) and 442 lb-ft (600 Nm).

The BMW xDrive40e will cover the 0-62 mph (0-100 km/h) run in less than 7 seconds and should do 20 miles (32 km) on electric power during which it can hit 75 mph (120 km/h).

A full reveal is expected at the beginning of October during the 2014 Paris Motor Show.
