The latest bit of news comes courtesy of Motor Authority, that points to last year's unveiling of the M5 in Geneva just as sales were about to begin a few months later. According to MA, the M3 will be powered by an all-new 4.0L V8 that will send 420 HP through a newly developed dual-clutch DSG-like transmission. Knowing that lightweight materials are essential to beat out rivals like Audi's RS4, the upcoming IS-F and the forthcoming C63 AMG, BMW may employ carbon fiber in some of the M3's body panels.
Our crew is beginning to pack our bags, power adapters and photo equipment for our jaunt to Switzerland, so rest assured that if BMW does drop the M3 next week, you'll be looking at pictures and reading the details shortly after the veil is lifted.
