In 2022, the Dakar Rally will be held in Saudi Arabia, with a total length of 8,375 kilometers, which is 729 kilometers longer than the previous one (both in Saudi Arabia), and the difficulty is greatly increased. It can be called a "repair shop" to test the performance and endurance of the car. Among the racing teams in various countries, it is worth mentioning that BJ40, the only team representing China automobile brand, will hit the peak of this event for the second time.
Increase the difficulty, or become the most cruel off-road "battlefield" in history.
In previous Dakar Rallies, the participating vehicles have to cross the endless desert, rugged and steep rocks, even muddy swamps and other complex and difficult road conditions. Every stage hides difficulties that ordinary people can't imagine, and dangers will happen at any time. The 2022 Dakar Rally, which has been upgraded in difficulty, has become the cruelest cross-country trip in history.
At present, the track information of the Dakar Rally in 2022 has been initially announced, which is divided into 12 stages, from Wheeler to Riyadh, and then to Jeddah on the Red Sea coast, with a total length of 8,375 kilometers; Compared with last year's 7646 kilometers, it is equivalent to an increase of one day's race schedule, which is definitely the top test of endurance for both participating vehicles and racing drivers.
In addition to the extension of the schedule, the geographical environment through which the schedule passes is also quite bad.
Taking the first half of the competition as an example, the participating teams will probably experience the process that Serrat Mountain extends to the East Dehna Desert. The terrain of this trip is ups and downs, and the landform changes greatly. It can be described as "the green mud mountain is formed by many circles, and every hundred steps, it has to turn nine times between its hills". Moreover, driving in gravel environment is undoubtedly a great test for vehicle performance, engine high temperature resistance and passability.
In the first half of the race, it is difficult to get up to the sky, and in the second half, it is even more difficult: in the second half, the teams have to cross the desert of the Arabian Plateau, and they are greeted by hot, dry and overwhelming sand, which is described by a poem as "yin, yin, darkness, wind and dust". Obviously, such harsh desert road conditions are extremely severe tests for the chassis, suspension, engine, gearbox and four-wheel drive system of the car.
In the face of such a difficult competition, what are the killers of Beijing cross-country?
As the flagship brand of off-road vehicles in China, Beijing off-road vehicles have advantages over their peers in terms of off-road vehicle technology and manufacturing experience. Even in the face of such a hellish competition as Dakar, the Beijing off-road vehicle team still has the determination to cope with it calmly. The most famous race in Dakar is the "marathon stage", and drivers no longer have spare materials. This stage not only tests the absolute power output of the car, but also is extremely important for endurance requirements. If there is a slight deviation, there will be a situation of "cutting off oil" and retiring. Therefore, the power and endurance performance of the participating vehicles must be excellent, which is not only a requirement for rally cars, but also a quality that high-standard off-road vehicles should have.
Beijing Cross-country BJ40 is the crystallization of pulling technology under the baptism of major pulling events. The BJ40 Blade Hero Edition is equipped with a 2.0D diesel engine and an efficient ZF 8AT gearbox, which can easily achieve a cruising range of more than 1000 km, even in uninhabited areas, without worrying about the risk of oil cut-off. At the same time, the maximum power of 120kW and the peak torque of 380n·m fully meet the needs of users for long-distance crossing and strong dragging climbing.
This diesel engine of Beijing Off-road BJ40 is durable in addition to its outstanding endurance. At the same time, thanks to good heat resistance, the power system will not overheat even if riding in the hot desert. In addition, the inherent advantages of low speed and strong torque of diesel engine are more in line with the needs of extreme off-road players.
Anti-roll frame cross-country old gun is also a necessary safety configuration for racing cars.
Bad driving environment not only requires the general manager, but also the body structure. The "Dakar" stage is mainly rugged unpaved roads such as desert, gravel and hills, and vehicles have to fly at a speed close to 200km/h, which puts high demands on the strength of the car body structure. Most racing cars use steel tube bodies, which can achieve the strongest body safety while reducing weight.
Beijing cross-country BJ40 has the same design concept. It adopts the multi-closed-loop beam frame structure of 10 years ago, and is equipped with the only anti-roll frame of the same level in China, which not only improves the strength of the car body, but also ensures the safety of off-road vehicles to the greatest extent, even if it rolls, it can well protect the life safety of drivers and passengers.
Non-load-bearing body structure, five safety ring structure is adopted in the front finger beam of double fork, roll cage and body frame. , ensuring the ultra-high strength of the car body. At the same time, the embracing front finger beam of this car can effectively transfer the collision force to the body, realize the dispersion of the impact force, protect the occupants and the body, and stress the whole body, greatly improving the driving safety.
At the same time, Beijing cross-country BJ40 adopts the necessary weapon of rally level and the professional cross-country chassis with girders. The biggest advantage of the girder is that it can bear the load: you know, in such an extremely harsh environment as the Dakar Games, the impact of the road surface on the chassis is huge, and these impacts will be "carried down" by the girder of the chassis to avoid the deformation of the car body.
Moreover, the Dakar Rally is mainly a desert stage with gravel roads. Affected by the wind, it will also form soft sand dunes, which are easy to get stuck in the car, and the requirements for vehicle passability are extremely strict. In fact, for a professional hard-core off-road vehicle, passability is also a very important indicator, such as "cross shaft, shell pit, hero slope" often mentioned by Mr. Off-road Six, and so on. BJ40 has achieved ride comfort all the way by means of high passability angle and part-time 4wd+ "three locks".
Conclusion:
"It is difficult to strike while the iron is hot." It is precisely because of the full confidence in its own strength that Beijing Cross Country has the confidence to participate in the 2022 Dakar Rally, which is upgraded in difficulty. At the same time, as the flagship product of Beijing cross-country, BJ40 series is not only synonymous with feelings, but also a representative of strength. This car is full of pure cross-country blood that really conquers every extreme event! It is reported that the mass-produced 2022 BJ40 Ring Tower Champion Edition will also be listed in the near future, which is bound to set off a new wave of off-road market in China!
