Next generation F30 3-Series, spied while testing, is expected to be larger than current E90 model. This 4-door sedan prototype is sporting a split dual exhaust, hinting that it may be a 335i edition.

Featured here are the latest spy shots of the upcoming F30 next-generation 3-Series from BMW. Our previous shots can be seen here.

This 4-door sedan prototype is sporting a split dual exhaust, hinting that it may be a 335i edition. But when we look inside we seen none of the tech goodies we would expect from a higher-end model.

Getting a glimpse at the cabin of the next-generation 3-Series, we see a dashboard cluttered with camouflage and what is visible is just old electronics - there's not even an iDrive system. It's also a manual transmission. There seems to be a yellow patch hiding something on the steering wheel - perhaps a new function button. Or maybe the test engineer just stuck a Post-it note on there.

What we do know, or are expecting, is that the next 3-Series will grow, as each subsequent generation of it has over the last decade or so. The F30 3-Series should have a longer wheelbase than the current E90 model, perhaps going as far as being 2.8 meters (110.2-inches) long.

The 2012 BMW 3-Series sedan is due for a European market release in 2011. The North American launch should follow shortly afterward.
