BMW's new M3 sedan has been spied testing once more, this time with less camouflage, ahead of a rumoured unveiling in early 2013.
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.
The regular 4 Series Coupe and Cabriolet, built on the same platform as the new 3 sedan, are expected to arrive in the six months following the sedan's debut.
The differences will reportedly go beyond bodystyle and badges, with the M4 expected to be an even more hardcore, performance-focused half of the M3 and M4 lines.
Both models are expected to utilise a twin-turbo six-cylinder engine, retiring the current 309kW V8 mill and boosting output to around 335kW.
