The 2007 BMW 6-Series will feature a minor facelift, and an undisguised mule has been snapped undergoing testing at the Nurburgring. How minor a facelift? Well, you'd probably have to put the new one next to an old one to tell the difference.

Purely cosmetic changes seem limited to a revised front bumper, with the integrated fog lights moving slightly closer to the center. Mechanically, the car is expected to remain the same, though the twin-turbo six might find its way into the lineup.

The 6's styling is a love-it-or-hate-it affair, so if you like the Bangle design you won't be disappointed, but if you were hoping for a revolutionary redesign, you'll be waiting a while longer.
