The initial idea considered was a 4 door M3 saloon and a 2 door M4 coupe. But recently BMW has changed their minds and keep the legendary M3 coupe alive. Internal pressure from the BMW board was too great to kill it off. Therefore, the M3 coupe, M3 saloon and an M3 cabriolet in addition to an M4 2 door coupe/cabriolet will be developed. Did you get all that?
(Edit: The M4 will be a coupe/cabriolet = 2 door coupe with folding hardtop)
The M3 coupe will feature a 6 Series like glasshouse with the possibility of a new distinct interior. The front will sport a new aggressive yet subtle bumper while the rear will display quad exhausts like the new M5. Power will come from a new lightweight V8 producing around 400hp and uses the latest dual-VANOS variable valve timing system. New engine building technology and lightweight materials mean the engine should amazingly weigh the same as the outgoing 3.2 liter in-line 6 cylinder from the current E46 M3 but with considerably more power.
During early testing of the cabriolet version of the 3 series BMW experimented with both a normal canvas roof and a hard folding top but decided on the canvas due to weight savings and maintenance.
The new M3 is slated to arrive in early 2006 with a 2005 Frankfurt debut and the cabriolet will have a Geneva 2006 debut with sales beginning in summer 2006. The SMG transmission will come standard and a CSL version of the coupe with excess of 420hp is being planned as well.
The M4 will also feature theV8 engine mentioned above in the M3 and should go on sale later. No further details are known. A concept for the regular 4 Series is slated for Frankfurt in September.
