The upcoming 2013 model of BMW M4 has been digitally rendered. Though the 4 Series itself is yet to enter production, it is not yet certain when the M4 will hit the tarmac. But according to the rendering here, BMW M4 will sport a new front bumper and LED headlights along with a wide track and altered side air intakes. An aggressive looking front fascia, carbon fiber roof and larger wheels and brakes are also evident.
Where engine updates are concerned, the new BMW M4 should sport a different engine other than the regular V8 engine which was earlier seen in the BMW M3 models. According to experts, a twin turbocharged inline six engine with output of 450 hp is expected. This engine is definitely more powerful and will have greater fuel efficiency that what was offered on the M3.
The new BMW M4 will be dropping the usual V8 engine used in the M3 models and will replace it with a twin-turbocharged inline-six engine with an output of about 450 HP. That means it will possess 35 more HP and 100 lb/ft torque and will be fitted with a start/strop function as well. This will allow the M4 to be both more powerful and more fuel efficient than that the M3.
