A bigger-looking 2012 BMW 3 Series was spied testing on Munich roads recently. It launches in 2011 as a 2012 model.

More spy images of the 2012 BMW 3 Series are cropping up. These were taken on the streets of Munich where it is undergoing further testing. Due to the black and white body disguise, important details and key design characteristics are quite obscured. But it does look like some dimensional gains were made, especially on the length of the car. While this may be, engineers are working on solutions to keep weight down and efficiencies up.

The 3 Series is BMW's most important model and is therefore the one always in the middle in terms of design extremes. It tries not to offend while simultaneously pushing the styling envelope.

Handling is expected to be top notch if not class-leading. Complimentary engines will include petrols (turbo and non-turbo), turbo diesels and possibly a hybrid. The M3 model, anticipated for a 2013 launch, is rumoured to feature a smaller turbocharged motor in line with other current M cars.

Countries currently manufacturing the 3er include Egypt, South Africa, Germany, Russia and India.
