In 2013, BMW will introduce the new F80 BMW M3 Sedan. In this new spy video, the upcoming M3 can be seen during the winter testing sessions in Northern Europe.
The 2014 BMW M3 Sedan builds atop the newly unveiled F30 3 Series and will incorporate the usual M design cues, both on the inside and outside.
The prototypes spotted reveal a typical M3 with a wide track, M front bumper, square LED headlights, large brakes and the signature four exhaust pipes at the rear.
The biggest mystery comes from under the hood. We initially reported that a V6 engine with three turbochargers was being considered to replace the award-winning, now retired, V8 naturally aspirated unit, but recent reports indicate that BMW will most likely use an inline-six turbocharged engine.
Will there be a third turbocharger like the electric ones revealed in the new M550d? We will find out later this year.[Source: f30post ]
