2013 BMW M3 Sedan Spied Ahead Of Rumoured Geneva Motor Show Debut

BMW's new M3 sedan has been spied testing once more, this time with less camouflage, ahead of a rumoured unveiling in early 2013.

A  'concept' version of BMW's new M3 sedan will appear at next year's Geneva Motor Show, according to new reports overseas.

American website Autoweek reports that the new 3 Series flagship will debut first in Geneva as a concept, followed by a production debut later in the year - likely at the Frankfurt Motor Show. 

And, if BMW's recent concept-to-production formula is anything to go by (think Gran Coupe), we can likely expect the M3 concept to offer an almost exact preview of the final car. 

Spied testing in recent weeks, the new M3 sedan continues the theme of its predecessor, packing pumped guards, a quad exhaust-tip arrangement, upsized brakes and larger intakes.

And, for the first time, the new hi-po Bimmer sedan has been spied with the familiar 'power bulge' bonnet.

The M3 badge will reportedly feature on the sedan only, with the Coupe and Convertible versions expected to figure in a new 4 Series range - making for an all-new M4 pair.
