With the anticipation of fans around the world at its peak, the BMW M GmbH introduced the newest member of its product family intimate. For the first time, M coveted badge has been given to the popular 1-Series BMW 1-Series in the form of all-new BMW M Coupe. Badge M submitted after two years of the development process through the BMW M engineers and test drivers achieve extraordinary power delivery and a signature, near-perfect driving behavior of the BMW M cars. 2011 BMW 1-Series M Coupe will be available in limited quantities and with limited options on the Official BMW Center in Spring, 2011.
"Eigenwillig," the German word for "self-willed," "individual," and "decided to go their own way," has been the right word to describe the M car is unique and impressive than the last three decades. With the original 1988 BMW M3 as his inspiration, 2011 BMW 1-Series M Coupe combines the raw ability of a racing car with the agility, flexibility, and a seated position from a compact sedan to the BMW Ultimate Driving Machine ® makes pure. Thus, the BMW 1-Series M Coupe continues the tradition of BMW M. eigenwillig With the latest two-door model, BMW M is to describe the ability to build a performance car racing into a small car, capable of daily use.
Dimensions and Construction
New BMW 1-Series M Coupe has been developed for near-perfect balance and footprint, a large square. It is 71 inches (1803mm) wide - 4.8 inches (122mm) wider than its 1988 ancestor M3 - but only 1.3 inches (33mm) longer at 172.4 inches (4379mm) long. New BMW 1-Series M Coupe weighs in at 1495 kg DIN (£ 3296, the beginning), and features a wheelbase (2659mm) 104.7 inches, three inches longer than the M3 of 1988. Front and rear track width is exactly the same on the BMW 1-Series M Coupe at 60.7 inches (1542mm) each. Compared with 2011 BMW 135i Coupe, BMW 1-Series M Coupe is 0.2 inches (5 mm) longer, 2.1 inches (53mm) wider, 0.5 inches (13mm) taller, and rides on a 104.7-inch same (2659mm) wheelbase. Features a track 2.8 inches (71mm) wider in front and 1.8 inches (46mm) wider in the rear, and DIN weight 35kg (77 lbs, preliminary) less.
New BMW 1-Series M Coupe features a high strength steel unibody, with a unique, widened fenders and rear quarter panel to house track widened substantially. He also has a metal roof panel that saves about 35 lbs (15kg) compared to the BMW 1-Series models are equipped with a moonroof. 2011 BMW 1-Series M Coupe, built as one of the most BMW vehicles performance-oriented in recent years, may not be offered with a moonroof. This weight savings - at the highest point of vehicle - provide an appropriate reduction in the center of gravity, which contributes to enhanced driving dynamics. It also helps maximize head room (or space helmets, such as might occur).
Engineering chassis is "faster than the engine"
Providing sure-foot responsive handling for high performance, powerful and luxurious coupe, while keeping mass under control, presented many challenges for the engineers of BMW M. The result is an aluminum suspension which was originally for the current generation M3, and tuned specifically for this model in the BMW M Nurburgring Nordschleife test center. Of course, every BMW design begins with preparing the main components in a way that allows near-perfect front / rear weight balance (51.7/48.3).
Almost all aluminum front-end components, including front struts, swivel bearings, central subframe and an additional impetus panel below the engine serving to maximize lateral stiffness of the entire front.
At the rear axle, subframe, transverse arms, arm track, and wheel hubs have been reviewed by M to the ideal kinematics, geometry and stiffness. Virtually every detail on the five-arm rear axle made of aluminum and a new generation of BMW M cars, including aluminum dampers.
Both front and rear axles feature hollow bar anti-roll optimized for function and body weight. Combining two additional longitudinal reinforcement bars, axle kinematics tailored to the perfect way to track a whole and the character of the car. As a result, both in terms of stability and weight, according to the balanced performance concept of every BMW M vehicles.
Compounds Brakes and Wheels
A powerful braking system suitable for a car with performance that far was originally developed for the current generation BMW M3. The players internally-vented, cross-drilled iron discs measure 14.2 inches (360mm) diameter in front and 13.8 inches (350mm) at rear. Featuring large compound disc brakes and electronic anti-lock, stopping power for the BMW 1-Series M Coupe a strong, precise and consistent. Each disk is connected to a floating aluminum hub by cast-in stainless steel pin. This configuration reduces the thermal load on the disk, thus improving their performance and service life. An electrically-driven pump provides the vacuum system.
Service - and safety - is enhanced thanks to an integrated wear indicator which, through a dash display, allows the driver to monitor the condition of brake. Brake Service - closed for four years or 50,000 miles under the BMW Ultimate Service - thus can be given when necessary without guesswork.
BMW 1-Series M Coupe is equipped with a wheel, M light-alloy-specific cross-talk from the M3 Competition Package and GTS limited-production M3. They measure 19 x 9 inches with low-profile tires 245/35/R19 on the front and 19 x 10 inches with tires 265/35/R19 in the back, and silver in color.
In the BMW 1-Series M Coupe, the transmission power to the rear wheel also provides an ideal base for exciting driving dynamics because of segregation of duties consistent drivetrain and steering. Steering rack-and-pinion equipped with hydraulic power steering system called Servotronic, which regulates impulse in relation to road speed.
Heart of every BMW is the engine, and an inline-6 with exceptional performance, behavioral free-revving, and pushing and shoving endless BMW 1-Series M Coupe. This concept is known: in the history of BMW M models, high-revving inline-6 is one of the classic machine formats. In the second and third generation of the BMW M3, the-inline 6 became famous because it combines high output, sharp response, and a loud voice. In the BMW 1-Series M Coupe, the inline-6 engine concept embodied in the most up-to-date form.
twin-turbocharged, all-aluminum, 3.0-liter inline-6 engine is characterized by instantaneous response to accelerator pedal, sounds fantastic, and free-revving spirit. The combination of low-mass turbochargers and twin BMW High Precision Injection direct offer naturally-aspirated engine output will only be able to provide through movement of more cylinders and bigger.
The system was developed for the engine turbocharger 1-Series BMW M Coupe maintain high output throughout the engine speed range. Maximum output of 335 hp (250 kW) delivered at 5900 rpm. nominal peak torque is 332 pounds-ft (450 Nm) from 1,500 rpm to 4500 rpm. Redline is 7000 rpm. An enhanced engine management system BMW 1-Series M Coupe includes electronic overboost function which briefly controlled increase torque at full load conditions by another 37-lb ft (50 Nm). This peak torque of 369 temporary lb-ft to give the car a substantial increase in acceleration. BMW 1-Series M Coupe will complete the sprint from stop to 60 mph in just 4.7 seconds (0-100 km / h in 4.9 seconds). Signs emerged standing quarter mile in 13.2 seconds. Top speed is limited electronically to 155 mph (250 km / h).

New BMW 1-Series M Coupe is also equipped with steering wheel-mounted M button Drive which makes its first appearance in 2006 M5. In the BMW 1-Series M Coupe, M button to activate the program sharp throttle response for the sportiest driving. This means that the engine performance characteristics can vary according to the driver's wishes.
6-speed Manual Transmission
A ratio 6-speed manual transmission is used for transmission power close to the rear wheels on the BMW 1-Series M Coupe. It is specifically designed to interact with high torque engines and have been suitable for this purpose with flood cooling system dry. A flywheel upgrade to high-torque applications installed between the engine and transmission. This transmission is operated using a lever M is very short gearshift. final drive ratio of 3.15:1.
Variable M differential lock, DSC with M Dynamic Mode
BMW 1-Series M Coupe is equipped with variable M differential lock. This produces the locking torque on-demand and variable, thus providing optimal rear-wheel drive traction on all road surfaces. The key response variable M differential rotation velocity difference on the right and left rear wheel, direct drive torque in a split second. So where there are significant differences in the coefficient of friction between the right and left rear wheels, for example, optimum traction and propulsion possible maximum is guaranteed. Centrifuge principle of variable M differential lock to support the dynamic nature of both rear wheels on slippery surfaces and when accelerating out of bends.
This gives the BMW 1-Series Coupe M benefits traction on slippery surfaces, snow and sand. It also supports auto-sporty style in the narrow, winding roads like a mountain pass since the optimum traction and a maximum torque available drive when accelerating out of corners. So in this model, the variable M differential lock proves ideal support for the dynamic nature of rear-wheel drive.
Dynamic Stability Control (DSC) from the BMW 1-Series M Coupe includes elements such as Antilock Brake System (ABS), a function of anti-slip control (ASC), brake assistant Dynamic Brake Control (DBC), hill-hold assistant to start off, Cornering Brake Control (CBC), the function of brake fade compensation and Brake drying function. In wet or slippery surfaces DSC secretly intervened to limit oversteer.
As an alternative to the status of normal operation, the driver can activate the M Dynamic Mode (MDM) MDM by pressing the button between the front air vents, increasing the threshold of intervention of the DSC system. MDM allows very little oversteer dynamic in specific situations to enable the vehicle yaw optimized for maximum performance. Demonstrations at the BMW Performance Center in Spartanburg, SC has been shown to activate the MDM mode lick the fastest-possible performance while still providing assurance and protection of the Dynamic Stability Control. MDM also facilitate the start of the snow or loose surface carefully controlled amount of wheelspin. DSC can be entirely disabled via a press-button long MDM (ABS remain active.)
Innovative Aerodynamics: Water Curtain
Consistency of form and function is very important for engineers at BMW M, the search for the perfect balance of various factors aerodynamics in wind tunnels. As a result, the BMW 1-Series M Coupe is equipped with the latest innovations BMW aerodynamics. air curtains, used here for the first time in a production vehicle BMW, enhance airflow around the wheel arches with the benefits of turbulence are significantly reduced.
Innovative aerodynamic features consist of openings on the outside bottom of the front fascia that routes high-pressure air through channels in every corner of the front. Channel approximately 10 x 3 cm wide and is designed to channel air to the openings in front of each wheel arch, where he disposed of through a very narrow hole at high speed. Air flow out covers the side of the front wheel like a curtain, thus reducing aerodynamic turbulence that is not profitable in the vicinity of rotating wheels.
This feature has a key role in the development of aerodynamic innovation future. An example of the principle of the air curtain was first presented in the BMW Vision EfficientDynamics concept study at the International Motor Show (IAA) in Frankfurt in 2009, and the developer BMW 1-Series M Coupe takes the task of pioneering application of this element for the production vehicle. To do so, they utilize the unique capabilities of the new full scale "rolling road" wind tunnel testing at the BMW Group Aerolab Aerodynamic Center.
There are three exterior paint finish to choose from for the BMW 1-Series M Coupe. In addition to non-metallic Alpine White and Black Sapphire Metallic, Valencia Orange Metallic available exclusively for high-performance compact sports car.
Strongly shaped front fascia is dominated by three large air intake that is safe for air cooling of high-performance engines. Air enters the central area is covered by a honeycomb grille-structured, while the two outer intake that actually open. This means that in every situation on the road or track, a number large enough cooling air is fed directly into the engine oil cooler on the right and to the additional cooling radiator on the left.
