Yesterday we saw images of BMW’s next-generation 7-series saloon testing at the Nurburgring and now we have the first shots of its long-wheelbase (LWB) cousin. As expected, the LWB model features an extended wheelbase and stretched rear doors to accommodate extra space for rear-seat passengers. The latest spy shots also reveal more of the car’s rear-end, revealing the outline of the new bumper plus the design of the exhaust tips and diffuser.

The new BMW 7-series is expected to be officially revealed next month before make its world debut at the London Motor Show. It will eventually go on sale at the end of the year as a 2009 model.

Some of the premium features of the car include a new torque-splitting differential on the rear axle, an upgraded radar cruise control system and a camera-based lane departure and blind-spot warning system. There’s also expected to be a new night vision system with pedestrian and speed sign detection features. The new 7-series is also expected to debut BMW’s new hybrid technology, the same two-mode system developed jointly with Daimler, Chrysler and GM.
