BMW 3-series convertible

BMW's 3-series cabriolet is due for a makeover! These latest pictures show a mildly disguised convertible during some late stage testing before the cars early 2010 release.

It looks like the updated car will gain a revised rear bumper and lights as well as a tweaked grille and front fascia. Other styling changes include new side sills and freshly redesigned wing mirrors.

Elsewhere, the improved iDrive system from recent BMW's will likely feature as well as the mobile internet software called ConnectedDrive.

Additions to the engine range are possible with the most likely being the 2.0-litre EfficientDynamics diesel engine offering an impressive 56mpg.

The updated car will be officially unveiled at the Geneva Motor Show in March.
