“GHOST HIGHWAY”

Sports BMW M5 super-sedan release in 2004. Sports BMW M5 super-sedan release in 2004. Among car owners can always find many of those who have gambling, sports in nature — they prefer cars with ordinary appearance hides a family car racing car. For the first time the beauty of owning such a supercar has been brilliantly described in the novel by Erich Maria Remarque “Three comrades”, whose protagonists are equipped with a racing car the most common, is not a racing body. “Charles — Ghost highway” that could develop a top speed of 200 km/h, was on the German autobahn out of the competition…

 
After 45 years since the release of the novel in the light of the idea of creating such a vehicle was adopted talented engineers and marketing strategists at BMW Motorsport GmbH, the then division of Bayerische Motorenwerke. They suggested that the installation of powerful high-efficiency engine in visually inconspicuous sedan will allow you to create as a result of this effective combination of a completely new class of vehicles — class supersedanov. Thus, in 1984 there was the first BMW with an index of the M5 — car concept for the past 20 years remains the most innovative and successful in its segment
 
The first generation of the BMW M5 (1984 — 1987)
 
The owners, who wanted to be under the hood of his sedan powertrain of a sports car, but, nevertheless, did not want to stand out from the crowd, there were, apparently, from the beginning of the automobile age. These desires are embodied sometimes in a single day supercars. And on an industrial basis, this process has been put in the middle of 1980-ies of the BMW Motorsport GmbH. To this end, it was two of the most important “ingredient” — on the one hand, 6-cylinder in-line engine with a capacity of 286 HP from centralnorthern sports car M1, and on the other hand, the body then BMW 5-series for its placement.
 
Appropriate traffic safety provided adapted to the increased possibilities for sports suspension with gas-filled shock absorbers, special tyres Michelin dimensions 220/55 VR 390, enlarged disc brakes, specially tuned anti-lock brake system and serial locking differential with a locking rate of 25 percent. This the first BMW M5 accelerated from standstill to 100 km/h in just 6.5 seconds and its top speed was 245 km/h. Thus, it was the fastest sedan of its time and, despite his technical ability, spent a total of 11.3 liters of fuel of type Super per 100 kilometers.
 
If the buyer wanted to order for my M5 special equipment, the BMW Motorsport GmbH had given him full assistance. In total, Munich was made about 2200 of these supercars.
 
The second generation BMW M5 (1988 — 1995)
 
At first BMW M5 of the second generation was produced with an engine power of 315 HP with this engine the super-sedan for the first time entered international markets and made it a very favorable impression. In the future, these machines are equipped with inline 6-cylinder 340-horsepower motors — one of the most powerful ever produced by BMW.
 
The appearance of the car BMW M5 of the second generation were more cautious and individualized in comparison with the predecessor; its exterior is characterized by muscular front and rear aprons, side skirts with contrast color and unique design of the wheels. The engine served, in principle, the same exhaust the power unit from M1, but it had to be subjected to a major upgrade. As the design features of this motor can be called resonance intake system, which, depending on load and rotational speed of the crankshaft of the engine to change the length of the inlet pipe — the control unit resonance system was a proprietary development of BMW Motorsport GmbH.

Compared to a conventional sedan BMW 535i at the time, the body of the super-sedan was located 20 mm below, and for verspatung drivers as options were offered so-called package “nürburgring” (remember, the Nurburgring is a famous race track). In the basic configuration, the BMW M5 of the second generation had the knob height on the rear suspension system and a 25% locking differential. This high-power car accelerated from standstill to 100 km/h in just 6.3 seconds and a top speed, electronically limited, is 250 km/h.
 
Only in Munich was built about 12 thousand supersedanov BMW M5 of the second generation, which greatly exceeded the production of cars of the previous period.
 
The third generation BMW M5 (1998 — 2003)
 
If the design of high-power supersedanov the first two generations were very traditional restraint, the models of the third generation it has become much more attractive and solid. Impressive front and rear aprons, pronounced sills, “aerodynamic” exterior rear view mirrors, 18-inch wheels with twin spokes, four gleaming exhaust tailpipes — all this testified to the fact that the next BMW M5 is a veritable bundle of energy at the highest level.
 
Indeed, a 400-strong 5-litro-St 8-cylinder engine with a V-shaped arrangement of cylinders provided this car exceptional handling characteristics: the classic sprint from standstill to 100 km/h in just 5.3 seconds, a speed of 160 km/h the vehicle reached already in 11.6 seconds.
 
As in the previous model, the maximum speed is also limited by the electronic system at the level of 250 km/h But not only sophisticated equipment is different from the third generation of the BMW M5 from its predecessors. The other was the method of its production: the first release of the BMW 5-series was carried out along with other models on the Assembly line in Dingolfing. Engines for the M5 was hand-built on a special Assembly line in Munich. Only Bayerische Motorenwerke was issued more than 20 thousand supersedanov M5 of the third generation.
 
World premiere of the new BMW M5
 
New elite sport BMW M5 super-sedan became the most powerful, compared with the car’s predecessor-the mi: 5 litres, 10 cylinders, 507 HP power, torque of 520 N. m and the maximum engine speed over 8000 rpm, These indicators allow owners of these machines who prefer a sporty driving style, to have in one car and a sedan for the daily commute, and a luxury car for ambitious racing.
 
Excellent performance the new BMW M5 allow him, as the machines M5 series of previous generations, once again set the tone in the segment of sports supersedanov. High power, clothed in a simple form, this principle was always the same for all series cars, the M5 and the BMW M5 modern he was raised to new heights: thanks to the huge capacity of high-speed V10 engine paired with a 7-speed SMG transmission, this car allows the driver to experience a totally new sensation. It is among supersedanov only BMW M5 has the most innovative drive concept, the best indicator of the specific gravity, impressive handling and, in addition, complete suitability for everyday use.
 
Modern cars typically are available with a variety of engines — both petrol and diesel. New serial BMW M5 is equipped with only high-revving power unit V10, the most powerful of those employed by BMW in production cars. However, capacity is not the only determining parameter for motor sports. In the series cars, the M5 is much more important than his agility and ability to disperse, which depend on the developed thrust (and it is from torque and gear ratios in the transmission) and the vehicle weight.

When you create a new engine dominant was the concept of high speed when using the optimum gear ratios in transmission and the main transmission, which guaranteed the implementation of a impressive traction. The crankshaft 10 cylinder engine spins up to 8250 rpm such rotation frequency of the hitherto inherent only to the motors sports cars. Compared with the previous 8-cylinder engine, the power increase was more than 25 percent, so that the power density of the new motor is on the level of sports models.
 
The camber angle of cylinders /-shaped engine is 90 degrees. It provides optimized vibration characteristics and comfort of the mass balance of the crank gear. With the aim of obtaining sufficient rigidity for the unit was chosen (this is the first V-type engine BMW) design type Bedplate (b) when the optimal support of the crankshaft in the bed of aluminum are filled with inserts of gray cast iron. They also provide acoustic and vibrational comfort and ensure a high melodiously ability. Exceptionally rigid crankshaft rotates in six bearings.
 
System infinitely variable adjustment of valve timing type “double VANOS” guarantees optimal gas exchange and allows you to ensure that the adjustment is carried out in a very short time. It should be noted that each cylinder of the engine V10 (similar to sports motors) has its own throttle valve, control of which is done electronically.
 
The exhaust system of the new engine, made of high quality stainless steel, does not have any connection on the way from the exhaust manifolds to the mufflers; the latter is equipped with traditional cars like the M5 four tailpipes. Exhaust emissions the engine complies with the Euro 4 standard and the American LEV 2 standard.
 
Outstanding performance power and clean exhaust of the V10 engine has been achieved thanks to the unique integrated management system MS S65, created on the basis of the most powerful processors of those that are allowed to be used in cars.

The most effective method of controlling the engine using the technology of ion current, which allows to define a spark plug of a possible detonation in each cylinder, to control the correct ignition and to detect possible faults. Spark plug acts not only as a fuse for the fuel mixture, but at the same time as the sensor to monitor the combustion process.
 
The new engine has been successfully implemented the concept of high-speed motor. This became possible when equipped with the powertrain sequential seven-speed transmission with carefully chosen gear ratios that allowed us to convert the developed engine torque in optimum traction. In contrast to the previous six-speed, the new seven-speed SMG transmission provides a more precise and extremely fast switching to manual, and driving comfort in the automatic mode shift. Well, more the seventh step allowed to reduce the jump speed and torque.
 
Control the seven-speed SMG transmission is done either by lever on the Central console or by using the so-called “petals” on the steering wheel. Compared with the previous box new perform allows you to shift 20 percent faster. This speed can, perhaps, be considered the limit — faster to switch steps in a box of similar design, no one has yet succeeded. This all happens smoothly and much faster that can make even the most experienced drivers, and the inevitable switching of the transmission interruption time is not actually felt — to the maximum speed of the BMW M5 accelerates almost without jerks
 
Some details about the function Drivelogic. With its help, the SMG transmission offers the driver a total of 11 variants of switches that allow you to tailor the characteristic of stage change to his driving style. Six of these programs ranging from balanced dynamic to pure sports — you can choose within the sequential manual shift (mode S). However, if you use the Launch Control function, the SMG Drivelogic transmission system independently shifts gears, and each transition takes place shortly before reaching the maximum frequency of rotation of the crankshaft of the engine and with optimum slip until the BMW M5 until reaches maximum speed (D mode).

The seven-speed SMG gearbox not only helps the driver to make maximum use of the engine and improves the traffic safety. So, in critical situations— for example, when downshifting when driving on a slippery road — it will instantly turn off the clutch skidding due to too energetic engine braking.
 
Also very useful system of trough-tion on the rise, which prevents the vehicle from rolling back, as well as detection of movement in the mountains, which moves on the climbs and descents moments of switching. When driving uphill thus, it is possible to avoid multiple switching “up and down”. During the descent from the mountains the same function longer included holds lower gears to maximize the braking torque of the engine.
 
The combination of power and torque characteristics of the V10 engine with a flexible seven-speed transmission SMG allowed us to obtain such performance, that series sedans until now was considered impossible. First of all, the new BMW M5 gives its driver an incredible sense of fun behind the wheel. This is not surprising if the car can accelerate from standstill to 100 km/h in less than 5 s, and the mark of 200 km/h through 15 of S. the Car accelerates uncontrollably until the speed of 250 km/h, when triggered by an electronic limiter. However, the speedometer is used to estimate to what extent could bring the car and its driver endless engine power, not restrained by the limiter: speedometer marked up to 330 km/h.
 
Objective verification of the responsiveness of the car on the most challenging race track in the world — the North loop of the legendary Nurburgring has revealed that the BMW M5, spending on a lap of about eight minutes, can be attributed to a thoroughbred sports car.
 
The design of the chassis of the BMW M5 and its setting allow us to consider this car as a completely independent model. The fact that the chassis and its adjustment system was developed for the new BMW M5 part again, part of a significantly modernized or adapted to the capabilities of the cars series M
 
The BMW M5 is equipped with a rear differential with variable lock, responsive to the rotational speed of the propeller shaft. This device gives the machine high resistance motion, and also provides optimum traction — especially on out of corners in Addition, adjustable differential lock able in the most difficult situations — that is, even at greatly differing coefficients of adhesion of the driving wheels is to provide a significant gain in traction. With the growth of the difference in rotational speed between the driving wheels is immediately increased and the time lock ensuring optimum traction in any situation.
 
Especially for the BMW M5 was developed the system of dynamic stability control (DSC), a new generation. To enable or disable it by pressing the button on the center console. Selecting programs, adjustment of dynamic movement is done by pressing the MDrive button on the steering wheel.
 
The first stage of DSC corresponds generally to the system configuration of the serial “five” of BMW; the second stage (dynamic mode) is designed for drivers who prefer sporty style.
 
The drive machine has a system of electronic adjustment of rigidity of shock-absorbers (EDC), which allows the driver to change its setting, from sporty to comfortable, using three programs: “comfort”, “normal” and “sport”. Management of EDC by the driver using the MDrive button on the steering wheel or the pressure switch next to the gear lever SMG.
 
The Power button changes the engine characteristics “on demand”. Sometimes the driver does not need all the engine power and the frenzied dynamism of the BMW M5 — for example, in city traffic. So after starting the engine, automatically enlists emphasized comfortable program P400, which uses “only” 400 HP Well, to get the full power of the 10-cylinder engine, just press the Power button close to the handle of the checkpoint. As a result, the engine will be more responsive to the movement of the pedal “gas” that allows the driver to program Р500 enjoy the sport, and P500 Sport racing uncompromising character of the car.
 
The giant power of the engine of BMW M5 demanded the vehicle’s equipment high-performance braking system with weight-optimised perforated composite discs enlarged diameter. Weight-optimised and rigidity floating two-piston clamps out of aluminum (like the BMW 7-series) M5 provide braking distance at the level of high-quality sport cars come to a complete stop when braking from a speed of 100 km/h requires only 36 m, and with a speed of 200 km/h — less than 140 m.
 
 
Specialists sometimes call a BMW M5 a wolf in sheep’s clothing. Indeed, the appearance of the basic “five”, representing a dynamic business class BMW, gives the impression of sportiness, elegance and vitality. BMW M5 distinguishes it from the many obvious and hidden details that generally reinforce the impression of vitality, confidence and dynamism.
 
Compared to the base model catches the eye are the redesigned front and rear aprons, BMW M5. Updated side sills, wider wheel arches of steel. According to tradition, the M5 differs from the basic “five” exclusive design of the exterior mirrors, four tailpipes which have become hallmarks of the brand, and exquisite wheel design. For the first time, the BMW M5 has acquired a beautiful “gills” on the front fenders.
 
Inside the BMW M5 is different from the very solid features of the base model even more noble leather trim in three color options or (for a fee) — full leather trim that is able to satisfy any “autogermana”. Significant differences from the series “five” can be seen in the dashboard, an optional projection display, adapted to the special conditions of cars of type M steering wheel with MDrive button and new designed Central console.
 
All cars created by BMW Motorsport GmbH, are characterized by the complete suitability for everyday use. To BMW M5 this applies, in particular, because this model remains all the same an elegant luxury sedan, despite the fact that its characteristics are rather peculiar racing performance. Sporting ambitions of the BMW M5 are not to the detriment of the comfort, availability of space for passengers and Luggage, as well as active and passive safety. Even the fuel consumption and environmental friendliness M5 can be safely put on a par with the standard BMW cars.
 
In conclusion, I would again like to remind readers about the novel, Remarque “Three comrades”, but rather about the episode in which after overtaking nondescript “Carl” luxury limousine owner behind the car immediately wanted to buy a bullet “Ghost highway” — and this despite his ordinary and very battered body. It seems that the creators of the BMW M5 — cars with a sporty “filling” and appearance series sedan — very astutely observed the psychology of the potential owner machines of this type.
 
Market research showed that buyers of the BMW M5 are predominantly male; they are married; usually they have a family has two cars on average 45 years, most of them have high level of education and income above average. Car owners M5 — it is mainly people of the most diverse liberal professions, focused on prestige and active lifestyle. Such sports activities as Golf, sailing, dressage or racing boats, they are exactly the same habitual, as well as exclusive travel to distant countries. For such to pay for the super-sedan the BMW no problem.
