Although the BMW 7-series has undergone some mild styling tweaks over the past few years, it seems that more is on the way, all in an effort to tighten the reigns of the mangled Bangled versions that caused drivers to bleed from their eyes.

Although some hope that the Concept CS will influence future 7s, the 2009 model will be more of an evolution, likely drawing cues from the redesigned 3-series. But the real changes are likely to come from underneath.

A longer wheelbase, partnered with a wider track, will be utilized to keep with BMW's handling ethos, while new engine choices, including a hybrid and twin-turbo V8 diesel will provide motivation. A new ZF eight-speed gearbox is almost certain, along with a revised iDrive system and several new safety features.

Look out for the refresh in 2009, with a full redesign sometime next decade.
