As expected, the 2014 Bmw M3 will be lighter, more powerful and faster than the outgoing model. According to sources that were not mentioned by AutoExpress, the new four-door version of the M3 (for those who don’t know, the coupe will be called the M4) will take the model to new heights thanks to the redesigned body and the engine technologies.
Apparently, the 2014 M3 will feature a blade front bumper, ventilated front fenders and aerodynamic side mirrors. Under the hood we will find a new six-cylinder 3.0-liter twin-turbo engine, which will be used exclusively on the M models, not like the 4.4-liter twin-turbo V8 engine found on the M5.
The total output delivered by the 3.0-liter twin-turbo engine is expected to reach 450 hp and 550 Nm of torque, which means a 30 hp and 150 Nm increase over the 4.0-liter V8 engine found on the current M3.
Furthermore, the 2014 M3 will be lighter and just like the current M3 Coupe it will get a carbon fiber roof and new lightweight materials that will be used for the bonnet and bootlid.
The new M3 will be 100 kg lighter than the current model. Regarding the performances, the 2014 M3 is expected to sprint from 0 to 100 km/h (62 mph) in around 4.3 seconds while the top speed will be limited at 155 mph or 250 km/h. A manual version will also be offered for M enthusiasts.
When developing new M models, BMW M GmbH has always included aerodynamics as one of the main elements to consider. Its engineer typically has to find ways to ensure that air flows around the car, thereby not only ensuring superb aerodynamic performance, but also making sure sufficient cooling is provided for the engine and brakes.
M models typically have a number of aerodynamic details that help reduce lift equally on both front and rear axle while ensuring optimal handling. These details include the dynamic front apron, smooth underbody as well as well-defined Gurney spoiler on the M3 Sedan or the integrated spoiler lip on the BMW M4 Coupe.
Biermann, Head of Development BMW M GmbH, remarked the manner that air is channeled through the engine oil cooler creates the so-called Venturi effect, thereby reducing front axle lift and improving steering.
M models also feature Albert Elements such as Air Curtain and M gills with integrated Air Breather, working to minimize turbulence on the front wheel arches. These elements -- along with the aerodynamically optimized exterior mirrors (in twin-stalk style) -- are some of the characteristic design features found on the BMW M3 Sedan and BMW M4 Coupe.
Both the BMW M3 Sedan and BMW M4 Coupe underscore the success achieved by M engineers in fusing the needs of everyday usage and the demands on the track.
