A test mule for the latest-generation BMW 7-Series has been scooped testing under the skin of a current model and is shaping up to be quite a special thing.

This is not the first time our spy photographers have snapped the new 7-Series out-and-about as in November last year, an electric 7-Series mule was spotted with very little camouflage. These latest spy shots show a more traditional combustion-powered prototype but due to a lack of badges, it’s hard to say what exact variant we’re looking at.

The most significant new model in the seventh-generation 7-Series family will be the arrival of an all-electric variant, potentially dubbed the i7. It is claimed that entry-level variants will feature an 80 kWh battery pack while the range-topper could sport a massive 120 kWh battery allowing for up to 434 miles (700 km) of range. It is claimed this flagship could also churn out as much as 650 hp thanks to a pair of powerful electric motors.

A number of petrol, diesel, and hybrid versions of the latest 7-Series will also be available from launch.

Because the test mule in question is wearing the skin of the current 7-Series, it’s difficult to say how the new vehicle will look until we start seeing prototypes wearing their production skin. If we were to guess, we’d say the new 7-Series won’t be radically different than the outgoing model but could sport sharper details including headlights and taillights as well as front kidney grilles similar to the Concept 4 and Concept i4.

The first full-body next-gen BMW 7-Series prototypes are tipped to be around 6-7 months away while the new car is slated to arrive in 2022.
