BMW will be sending its popular sports coupe into its fifth generation in just a few years time and that sendoff will be coming with the usual array of variations, as well as a new hatchback model inspired by the 5-Series GT.
The M3, now the M4, Convertible model will more than likely feature the current BMW’s retracting hardtop which folds away neatly in 22 seconds. The new design, however, will combine elements from the recently launched Z4, 5-Series, and 7-Series. It will be slightly larger in size, but with shorter front and back overhangs and its body will feature a mix of steel and ultra-light carbon fiber-reinforced plastic.
As far as powerplants are concerned, the 2014 BMW M3 has seen more than its fair share of rumors. The most interesting speculation is that the future M3 will be powered by a fresh 3.3-liter six-cylinder engine equipped with three turbos – one powered by electricity, rather than the exhaust gases. Its output will be around 450 HP (up from the current output of 420 HP). That rumor was recently shot down and replaced with a new twin-turbocharged 3.0-liter, six-cylinder engine that is currently under development. A source described the new engine "as being heavily differentiated from the company’s existing twin-turbocharged ‘N54’ and twin-scroll turbocharged ‘N55’ 3.0-liter engines." Apparently, the new engine will come with a management system, induction system, cylinder head, pistons, and connecting rods.
Rumors come and go frequently, so chances are we’ll still have to wait a bit to get any official confirmation of BMW’s engine choice.
