Say what you like, but Russian cars love extreme conditions for racing, almost for survival.
I remember that at one time, only on the Russian Niva, Finnish racers triumphantly marched through the African deserts - the routes of the Paris-Dakkar rally. True, what the “serial” monster from Naberezhnye Chelny KAMAZ 4911 did at these races cannot be compared even with the victorious march of the Togliatti car.
According to the FIA regulations, only production models can participate in the rally
Imagine an eleven-ton colossus, rushing at a speed of more than one hundred and eighty kilometers per hour. Imagine how it accelerates to “hundreds” in just ten seconds. Imagine it flying through the air (athletes skillfully use any natural elevation as a springboard) and landing on all four wheels without a “breakdown” of the suspension, and this is with eleven tons of curb weight.
Buy civil version anyone can use this monster - the price tag starts at $ 250,000
If you can imagine this at least approximately, then consider - you have a rough idea of \u200b\u200bwhat it is - pride and glory domestic automotive industry KAMAZ 4911 Extreme. Plus - the permissible operating mode in “ temperature range” from minus thirty to plus fifty degrees Celsius.
No magic, no fantasy
Usually talking about this legendary car, stray into an enthusiastic tone, describe its capabilities accompanied by many exclamation marks. As if the eyewitness was faced with a clear manifestation of either a technical miracle, or met aliens who own clearly unearthly technologies.
In fact, there is no magic here, as well as science fiction. And to everyone unique opportunities There is a clear and scientifically based explanation for the monster from Naberezhnye Chelny - the technical characteristics of KAMAZ 4911.
The YaMZ-7E846 engine is the heart of KAMAZ 4911
And they look like this. V - figurative "eight" produced by Yaroslavsky machine-building plant(YaMZ) has a volume of more than seventeen thousand cubic centimeters and develops a capacity of about eight hundred Horse power.
By the way, the engine for serial "SuperMAZ" served as the basis for the motor.
In addition, two Borg Warner turbochargers and four valves, two intake and two exhaust, for each cylinder add extra agility. Total, on this engine - thirty-two).
Fly so fly
And the fast KAMAZ is equipped with hydropneumatic shock absorbers from the army BRDM, which are designed for parachute landing of a multi-ton armored tracked vehicles, hence the fantastic “volatility” of a multi-ton truck. And besides, to ensure a smooth ride in the suspension, springs elongated to almost two meters are used, so huge jumps during the rally do not harm either the car or the crew.
Wheel formula 4x4, accompanied by a sixteen-speed mechanical box ZF and Steyr handouts with lock center differential give the truck fantastic cross-country ability. Since 2003, KAMAZ has climbed the podium in almost all world cross-country heavy truck races.
Everything is in superlatives
If we add to the above a lightweight supporting frame, equipped with inserts made of composite materials so that rigidity and strength are not affected frame structure, and the number of leaf springs - fourteen in front and ten in the back, then we get an approximate description of a car that wins the most prestigious world rallies with enviable constancy.
True, in the "combat", sport mode consumption of monstrous 800 - strong engine fluctuates somewhere within a hundred liters per hundred, but for a big sport, this, you see, is particular. No wonder the car is equipped with a twin fuel tank with a total capacity of one thousand liters.
The glorious sports past and present of the Master-Kamaz team are inextricably linked with the periodically improved and reworked production models of the automobile plant located in Naberezhnye Chelny, and KAMAZ 4911 Extreme - bright representative a family of cars that literally lifted the Russian rally team into the empyrean of world sports, inaccessible to rivals.
Civil version of the racing version - KAMAZ 4911 Extreme
Since the late 1980s, Russian trucks KAMAZ is among the undisputed world leaders in the most prestigious and eminent races. And finally, a joke (they say that the employees of Master Kamaz are very fond of telling visitors in all seriousness): during the crash tests of KAMAZ 4911 Extreme, the concrete wall, against which it was planned to break the front of the car, began to quietly crawl away from the test bench.
Racing is a very exciting competition. And a truck rally is an event to watch at least once in a lifetime. The stages are considered the most prestigious such world marathon. Year after year, many are amazed by the amazing Russian "car" - let's get to know him better!
KamAZ "flying"
Model 4911 Extreme - this is the legendary KamAZ participating in the Paris-Dakar rally, as well as in " Silk Road". This "graduate" of the Kama Automobile Plant, located in Naberezhnye Chelny (Tatarstan), is not only a sports truck. It is designed to urgently deliver goods, following the routes with axial load up to 78 kN, according to dirt roads and rough terrain. The machine can be operated in various climatic zones at a temperature of +50... -30°C.
Why was KamAZ from "Dakar" nicknamed "flying" by the fans? The car lifts off the ground with amazing ease and grace, like a giant bird. By changing the frame, the design of the springs, updating the flavors, the truck lands softly on the wheels when jumping, even from high altitude without harm to the crew.
The first flying truck race took place in 2003. Then, at the Telefonika-Dakar rally, the car took first and third place. More than once KamAZ 4911 Extreme became the winner of "Cappadocia", "Khazar steppes", "Desert Challenge", the championship and the Cup of the Russian Federation. And after the Dakar races, modernization and refinement of the car always followed.
French company "Eligor" and Russian factory Electron (Kazan) produces 1:43 scale models of this model of a sports KamAZ.

After we learned the technical characteristics of KamAZ from the Dakar, we will get acquainted with the team performing on this car in the rally.
Team "KAMAZ-master"
"KAMAZ-master" - Russian team racing drivers whose specialization is participation in rally raids. Performs only on KamAZ trucks. A regular participant in the Dakar rally (the former name of the Paris-Dakar rally) - Russians became its winners 14 times!
The team's birthday is July 17, 1988. It can be said that its composition is stellar - eight masters of sports of the international category, five winners of the World Cup. "KAMAZ-master" is considered to be the strongest team in its class. As well as excellent from "Dakar".
The permanent leader and mentor of the team is Semyon Yakubov, master of sports of international class. In the period 1996-2002. The pilot of the KamAZ-master was the well-known Vladimir Chagin. He has seven victories in the Dakar races, two World Cups, the title of "Best Russian Racer - 2003". The sponsor of the team is also serious - VTB Bank.
Results of the rally "Dakar-2017"
The last Dakar was held in Bolivia. Many participants recognized it as the heaviest in the history of the rally. And the fault is landslides, rains, mudflows. But this did not prevent KamAZ in Dakar-2017 from showing itself with better side. The KamAZ-master team returned from the competition, as in many past years, as a champion:
- The first among sports trucks was the crew of E. Nikolaev, E. Yakovlev, V. Rybakov.
- The second to finish was KamAZ D. Sotnikova, I. Leonov, R. Akhmadeeva.
"Gold" and "Silver" - awards of KamAZ in "Dakar" of the current year. Both the sports truck itself and its legendary team once again confirmed the title of the best in the world rally raid. However, racing is not the only path of the "flying" car. Among other things, it can be used for emergency delivery of goods - a car, jumping on springs, will sweep across the impassability with an arrow.

Data about technical specifications car -
from the official website of the KamAZ-Master team http://www.kamazmaster.ru/
Dakar 2018 is the last one in which cargo category it is allowed to use motors with a volume of more than 13 liters. For most teams, this makes little difference, since most trucks have been equipped with smaller engines for many years. But for KAMAZ-master, this change is significant - after all, the main engine for the team last years was a Liebherr V8 engine with a volume of 16 liters.
It is these engines that are on three of the four KAMAZ trucks at the current Dakar. On the fourth, under the control of Dmitry Sotnikov, an experimental 13-liter engine is installed, an in-line "six", which should become the power plant that will be installed on KAMAZ trucks in the future.
Changing the engine for KAMAZ-master is far from new. Over the years of rally-raid performances, the team has used power plants most different companies(KAMAZ, Cummins, YaMZ, TMZ, Liebherr), a variety of configurations (in-line "six", V8 and even V12) and the most different volumes(from 11 to 25 liters). About why KAMAZ-master used such large engines, and why other teams preferred much smaller engines, we were told by the technical director of the team Vladimir Guba.
Vladimir Guba: The reason for most of the teams to use 13-liter engines is simple: all the leading teams in the world of rally raids put on their trucks engines that are used in circuit racing, in the European Truck Racing Championship. There are strict regulations on ring trucks - an engine of 13 liters, 10 cylinders, single-stage supercharging. These are fairly advanced engines designed specifically for racing. There are teams MAN, Iveco, Mercedes. The Tatra team in rally-raids puts on their trucks the same engine that is used on the roundabout trucks of the Buggyra team. Therefore, in this regard, they are somewhat easier. They take a 1,200 horsepower, 6,000 Nm torque engine and de-boost it to 1,000 horsepower, 4,500 Nm.
But this is a special product. We can't do that, we don't have our own truck racing team. We tried to work with the Buggyra engine, but we cannot build trucks based on it, because we are a professional team, and our advantage is that we thoroughly know all the components of our car. We must be able to diagnose, test and repair them under any conditions. If we take a ready node, then, as a rule, we don’t know what’s inside it, we don’t have access to the program, we don’t even have access to diagnostics. That is, we are entirely tied to the services of the supplier. It doesn't suit us.
Therefore, we act in the opposite way - we take as a basis serial engine. This was also the case with Liebherr - we took a serial engine that was used on special equipment, and a separate modification was used on MAN trucks. But this is a serial engine with a capacity of 500 kilowatts, 700 horsepower. We forced it, brought the power up to 1000 horsepower. Now we are doing the same with the 13-liter Cummins engine. We took an engine with a capacity of 520 horsepower, and we are trying to get more than 1000 horsepower from it, we double the torque.
Cummins engines are also installed on serial KAMAZ trucks, but small, 7-liter ones. Recently launched the production of 9-liter. That is, in terms of volume, they still occupy the lowest step in the hierarchy of these power plants. We use a 13 liter engine. This is not our first experience with Cummins, they were on our trucks, including racing ones, back in the 90s. And already in 2007-2008 they used a 15-liter Cummins engine, with twin turbocharging. He didn't show himself very well. once again confirms the inefficiency of working with someone else's motor. It was made to order, and, of course, the manufacturer lays a certain reserve for the client's engine so that, God forbid, something happens. Therefore, its characteristics were not the best. However, we are now back to the Cummins cylinder block. But we are already developing everything ourselves, and we strive to approach the limit of its capabilities.
Now we are working with Cummins on the following terms: we buy engines of special configuration from them, they help us with spare parts and some information. But we conduct all developments, all changes, all refinements, all tests ourselves. Why Cummins? This choice was made for the simple reason that, according to the regulations, these engines must be mass-produced and installed on commercial trucks. So far, KAMAZ does not have such an engine, and waiting for it to appear and starting work only after that is a waste of time. Our Scientific and technical center(NTC) is currently working on a version of the 13-liter engine with very close performance. We are working ahead of the curve, and by the time it starts mass production we'll be ready. I think we will be able to quickly transfer all the experience to our domestic engines, and even then we will start driving our engines.
Despite the fact that our cars and the trucks of our competitors had engines very different sizes, they had about the same power. Why? Among other things, it is limited by reasonable limits. The maximum speed on rally raids is now limited by regulations at 140 km/h. For such a speed, in general, 1000 horsepower is enough. Excessive power is a load on the transmission, these are more complex operating modes, temperature, pressure, and so on.
Indeed, for many years, KAMAZ-master used a large displacement engine, 18.5 liters. We even once tried the Yaroslavl 24-liter 12-cylinder engine. But he was quickly abandoned because he breaks everything. Excess power. So we returned to the 18.5-liter, Yaroslavl, or now Tutaev engine. But this motor is quite old design.
It is not bad in design, but all-aluminum. The main thing is that it has aluminum heads. And they don't let you go out high degrees forcing. Everyone has modern motors cast iron heads. Therefore, in order to provide the same power, the degree of forcing was much lower - with an aluminum head it is impossible to achieve the same pressures, the same temperatures. Therefore, at the output, we received the same indicators, but with lower specific indicators. With less heat stress. With less stress on mechanical components and parts.
But then the maximum permitted engine displacement was reduced, and for the last couple of years, trucks have been running 16-liter Liebherr engines. It has approximately the same parameters as the Yaroslavl motors. We tried to reach out for more high performance in power, but V-engines have one feature - they have two connecting rods on the same crankpin. And the width of the earbuds is quite small, this is the most stressful place. That is, we reach a certain point - and that's it. Yes, theoretically, turbocharging and a fuel supply system allow you to reach greater moment, on more power. But it is no longer possible to increase it mechanically. Because earbuds, even the best ones, don't last. Due to the lower level of forcing, reliability was increased, and the resource of these engines was increased.
Now we are moving to an inline 6-cylinder engine, there is no such restriction. But there are others associated, for example, with a higher thermal tension. If our "eights" big engines, the exhaust temperature was about 800 degrees, now it has risen to 900 degrees. This is already significant. That is, such motors require a different approach, the use of other, more expensive materials.
Of course, a smaller engine has its advantages. In terms of mass, the 13-liter engine is 25 percent lighter. But, on the other hand, the in-line engine is longer and taller. That is V-engine about two cylinders shorter, and due to camber, it is lower, so under new motor we had to design the entire car from scratch. Changed the position of the engine, the location in height, in length. The position of the cabin has changed, because we could no longer use the previous one, above the engine - the cabin rises too high. Therefore, we were looking for new options in order to place the masses as efficiently as possible without increasing the height of the center of gravity. So, as usual in sports, there is no concept that allows you to always win - everything depends on the search for compromises.

* - bonneted truck, not used in Dakar rally raids
Years of use: since 2002 Until now
A special vehicle with a 4x4 wheel arrangement is designed for emergency delivery of goods to hard-to-reach areas on roads with an axle load of up to 78 kN (8 tf), as well as on dirt roads and rough terrain. The truck is suitable for operation in climatic zones with air temperature from -30 ° to +50 °С.
This racing four wheel drive truck nicknamed "flying" for the fact that he lifted himself off the ground with ease and grace. It was serial, which had no analogues in the main KAMAZ production (for serial recognition according to the FIA requirements of that time, it was enough to produce 15 cars a year, now - 50 in two years). On it stood turbodiesel engine YaMZ 7E846.10 V8 with a capacity of 830 l / s, with two BorgWarner turbochargers. The car was able to reach speeds of up to 180 km / h, accelerate to 100 km / h in just 10 seconds.
The classic rectangular platform was returned to the car. This happened because the organizers of the Dakar once again demanded that the participants bring their sports heavy trucks in line with conventional - serial trucks designed to carry cargo. In order to reduce weight, a thinner frame was installed on the truck, which, due to additional inserts, did not lose its power. The car has become “softer”, the smoothness of the ride has increased due to longer springs (1900 mm) and the modernization of hydropneumatic shock absorbers. The car was able to jump from a great height, landing softly on the wheels, without damage or damage to the crew.
The debut heavy truck race brought the team first and third places at the Telefonika-Dakar 2003 rally. In the same year, victories in the Russian Cup, the Russian Championship, the Khazar Steppes Rally, the Cappadocia 2003 Rally and the Desert Challenge followed. For several years, after each Dakar rally, the KAMAZ 4911 off-road vehicle was subjected to refinement and modernization.
