Bmw revealed today the official teaser photos with the upcoming 2011 1-Series M Coupe. Although the car is covered, showing a little bit of the front and rear ends. As you can see from the photos the car features a new front bumper with a larger air intake, a new rear bumper with integrated exhaust system and air diffuser. The design of the car is completed by the new multi spoke alloy wheels seen on the Bmw M3 with competition package.
Regarding the engine, the car will receive a turbocharged 3.0-liter inline six-cylinder engine capable to deliver around 350 hp. With this amount of power, the car is expected to hit 100 km/h (62 mph) in around 5 seconds, while the top speed will be electronically limited to 155 mph or 250 km/h.
The car will be available only with a six-speed manual transmission and will be available in a limited edition, exclusively for the United States market.
Inside, it is expected to receive new sports buckets, an M sport steering wheel wrapped in leather and fitted with paddle shifters. In addition, a carbon fiber trim level is expected to be seen at the interior, as well as a new set of aluminum sports pedals.
The BMW M model has always been able to achieve a balance between aesthetics, and actual performance of the vehicle. When you talk about function, aerodynamics will always be a relevant issue. The BMW 1-Series M Coupe addresses that in its excellent design.
Specifically, engineers have worked to improve aerodynamic drag and downforce. The M Coupe is the first of its class to include air curtains in its aerodynamic design. These curtains are able to reduce turbulence in the wheel arches, making it possible to maintain optimal handling for the M Coupe even in stormy weather conditions and at high speeds.
These air curtains are achieved when air passes through the front apron, where the air is channeled into two ducts. The ducts serve to pull air in and prevent it from hitting the tires themselves. Air passes through the two air ducts in the front apron and into another closed duct, leading to opening vents in the wheel arches.
These vents release the air at high speed, creating a curtain over the sides of the front wheels. The “curtain” acts as an airfoil that reduces turbulence around the area. As a result, whatever aerodynamics is created by the front wheels would be significantly reduced, improving performance.
The optimisation of air ducting in the area of the wheel arches creates especially high potential for optimising the vehicle's overall aerodynamic properties. This is why it has such a key role to play in the development of innovative aerodynamic measures.
An example of the air curtain principle was first presented in the concept study BMW Vision EfficientDynamics at the International Motor Show (IAA) in Frankfurt in 2009, and the developers of the BMW 1-Series M Coupe took on the pioneering task of applying this element to a serial production vehicle.
In so doing, they were able to tap into the unique research and development facilities provided by the Aerolab at the BMW Group's new Aerodynamic Testing Centre, where true-to-scale vehicle models are tested under realistic conditions. This technique effectively creates opportunities for designers to establish ways to optimize the aerodynamic properties of future vehicles in BMW’s lineup.
The air curtains now form a basis, one of many, for the development of new aerodynamic features in the design phase. The concept of the air curtain was first tackled by BMW during the International Motor Show (IAA) in 2009, after which the development team for the BMW 1-Series M Coupe was tasked to build on the concepts of the BMW Vision Efficient Dynamics study that was presented during the show.
The team took advantage of the Aerolab R&D facilities to create and test their applications of the concept, leading to the final results in the new BMW 1-Series M Coupe.
