BMW M1 Coupe is the most powerful version of the BMW 1 Series range. Will debut world premiere at the Detroit Motor Show 2011.limited series production
Although initially only 2,700 units would be manufactured, the same figure to be manufactured from RS3 Sportback Audi, BMW has confirmed that occur in series as the other models in the range of products, with a maximum of one year.
The rival of the new Sportback Audi RS3, TT RS, Ford Focus and Porsche Cayman RS500 R, will begin production in March 2011 and will be in production until the first quarter of 2011. In the penultimate quarter, will Cabrio body variant.
A worthy heir to the E46
Developed by M Power, the new BMW 1 frame M Coupé part of the mechanistic basis of the current 1 Series Coupé but conveniently tuned to transmit the driver the feel of a genuine high performance sports. To do this, take some elements of the suspension, steering and braking system of the older brother, the BMW M3 Coupé.
Creating smaller BMW's sports division has a weight of only 1,570 kilograms in running order. It measures 4,380 mm long, 1,803 mm wide, 1,420 mm high and has a wheelbase of 2,660 mm. Compared with the BMW 135i Coupé, 1M is 55 millimeters wide, thanks to the greater width of trains and tires.
M Power Specialists have implemented a system of front suspension double wishbones. They are made of aluminum and feature a tubular stabilizer bar that optimizes both the stiffness and weight. Thus, minimizing the deviations of the high lateral G loads and achieves a more effective front against the acceleration decelaraciones. The rear axle has been used a five-spoke aluminum tubular stabilizer bar. The latter is supported by two additional longitudinal bars to optimize the grip and the true path of the wheels.
Contact with the asphalt is carried out with different size tires on each axle, 245/35R19 front and 265/35R19 rear. Are mounted on aluminum alloy wheels of 19 inches in diameter with a spoke design in the form of Y.
With variable M differential lock
As the BMW M3 Coupé, the new 1M Coupé also features a limited slip rear differential with locking function of the differential variable. This feature allows, according to needs and circumstances, it can completely block the differential to maximize traction on any road, reacting immediately to any difference in rotational speed between the two wheels of the rear axle.
Like all models of BMW M, the new 1 M Coupé also features a powerful braking system with a high capacity to resist fatigue. Thus, the 1 M is the first high-performance compact discs have made in cast iron ventilated and perforated. They are so attached to floating aluminum hub by cast stainless steel pins with single piston calipers. The front discs measure 360 millimeters in diameter, while the rear has reduced to 350 mm. Both have a thickness of 30 mm.
Address precise, accurate and sensitive to the speed
In the BMW 1 Series M Coupe, the steering system is adopted rack and pinion with Servotronic power assisted. This address is known to offer excellent accuracy in the line and an excellent effect of care on the basis of speed.
The Servotronic steering allows, at low speeds, more comfortable to maneuver by applying an increased attendance and, therefore, less force at the wheel, while at higher speeds the assistance is reduced, providing a seamless drawn even more twisty sections . Thus, the driver has a very accurate perception of the angle of rotation of the wheels and better informed about the status of the road.
BMW 1 Series Coupe M systems have electronic driving aids, such as ABS anti-lock brakes, the system dynamic braking assistance DBC (Dynamic Brake Control), the hill start assistant and braking system CBC curves (Cornering Brake Control) and regulating the distribution of brake force curves.
The new BMW 1 Series M Coupe has details that are a function not only stylistic but also aerodynamic, which improve traction in highly dynamic driving situations.
The BMW 1 Series M Coupe is available in three body colors, one solid and two Alpine White Black Sapphire Metallic Orange in Valencia, only this version, identical to the BMW M3 GTS.
Carrier:
Regardless of body color the customer chooses, the cockpit has been designed for entering a new extreme sports atmosphere, with a design, colors and materials chosen specifically.
Although the interior design is the same as the normal versions of the BMW 1 Series Coupé has a distinct presence, with the dashboard controls and roof lining in anthracite color. Instrumentation clocks have the classic and traditional design M, with gray areas - the speedometer is calibrated to 300 km / h and up to 8,000 RPM tachometer - white lighting and red needles.
The doors have a dark lining Alcantara trim and anodized aluminum slats with the version name engraved on the doorsteps.
The sports seats in front and rear seats are upholstered in leather Boston design (black). The seats, the bellows of the shifter and hand brake are stitched with orange seams. M sport steering wheel multi-function keys.
The interior layout is four seats and luggage compartment has a volume of 370 liters.
Mechanics: the best back to basics
As the second and third generation of the BMW M3, the new 1 M Coupé reassemble an engine of six cylinders in line, a mechanical configuration that helped it to enter a special world of sport has a similar performance to the BMW M3 E36.
In the new model M, the propellant used is a variant of the N54 TwinPower Turbo (internally known as N54B30T0). This engine has an architecture of six-cylinder and three liters. Has a maximum power of 340 hp at 5,900 rpm and maximum torque of 450 Nm, available between 1,500 rpm and 4,500 rpm. It also has a new overboost function allows you to increase torque by 50 Nm (available immediately after each gear change.)
The BMW 1 Series M Coupé reaches 100 km / h in 4.9 seconds and has a top speed limited electronically to 250 km / h. To reach 200 km / h require only 12.4 seconds.
Efficient solutions
The BMW 1 Series M Coupe is a high performance sports waiver not to offer the utmost respect for the environment. Proof of this is that it has the same efficiency system than other BMW models. Has a system of energy recovery and a transmission brake activation secondary groups only when necessary.
Gearbox six-speed manual
In the BMW 1 Series M Coupe, the transmission of power to the asphalt is carried out through the rear axle through a new manual gearbox with six gears. It is specially designed to withstand high torque (has specific planetary gears and has an intermediate support of the main tree). Despite being manual, the gear selector has the classic design M.
