Mercedes-Benz Axor 2540 can be a good choice among used trucks


Will you be buying a used truck? Then see how the Mercedes-Benz Axor 2540 6 × 2 test was published in the print edition of the magazine. WORLDWIDE SHIPPING number 38. This model was produced until the end of 2011, as a 2012 model, and is quoted in the Fipe table at R$ 211,870 (September 2022). And the oldest Axor 2540 model is 2004, its price is R$104,461.

Axor 2540 is one of the tractors that come off the assembly line according to the buyer’s order, with different sizes of cabins and accessories. For evaluation, however, the car was prepared to take the long road: a well-equipped passenger room and plenty of space for era.

The model is one of the cars in the range with a 3rd axle from the factory and replaced the 1938 6×2. For the test, it was connected to a three-axle side trailer with pneumatic suspension. Due to the technical characteristics of the truck, the set was suitable for transfer with a PBTC (Total Gross Weight) of 57,000 kg.

The Axor family, as a whole, has impressed the road haulage industry. The cabin was an international product of Mercedes-Benz. Its development platform, although it seems strange, was Atego. It is produced in only three places in the world — Brazil, Turkey and Germany — and, therefore, it can be compared to the level of the passenger compartment available to European consumers. The differences were only in adjustments to the actual situation of each country. It would be a good move if the automaker didn’t give up on the production of a more robust truck to withstand the extreme impacts on Brazilian roads.

For evaluation, the Axor was designed with a high-ceilinged bedroom. In this version, the operator is not faced with obstacles to climb on the truck, nor to hold inside. The opening of the doors is generous when opening the way for users and the space is wide, comfortable and its organization likes practicality, where the rest and work areas are well defined.

The interior design was one of the well-established themes in the Axor. Despite the pronounced engine vault, the layout preserved the height and revealed new ways of framing the environment. The effort to make the floor as flat as possible revealed unprecedented solutions in the arrangement of elements. The fridge, for example, is under the bed, between the two storage rooms; there is room for a bunk bed and the roof console has several rooms.

Dashboard

In the sleeping cabin of the Axor with a high roof, what is missing is space and comfort for the driver. The internal distribution of areas is well defined, capable enough to define work and rest areas. Despite the security of the engine in the middle of the environment, the driver does not find it difficult to move around, for example, when leaving the steering wheel and reaching the bed. The secret to saving as much space as possible, especially in height, was reducing the floor to be as flat as possible. The solution benefited from the organization of interior objects and the comfort of the residents. The dashboard is well laid out to assist the driver during the journey. The wrap-around design leaves the instruments at arm’s length, without requiring the driver to take actions that take his attention away from the road or that cause him to remove his body from the rear. The seat, of course, has air suspension.

Engine

The Axor 2540 powertrain delivered performance that served its purpose. Its power comes from an in-line 6-cylinder engine that produces 401 hp at 1,900 rpm. Its torque of 204 kgfm appears quickly, at 1,100 rpm. A block, with electronic management, as well as a gearbox with 16 synchronized gears and a speed reducer on the hubs.

During the assessment

An excellent example of the good relationship achieved by the Mercedes-Benz engineers in the composition of the mechanical components of the set, was revealed in the strong lineage of Serra do Mar. Towards the coast of São Paulo, along the runway of Anchieta, the Axor was able to present a great ability to deal with cranes. Despite carrying 40,380kg, less than the 57,000kg it could travel with, the model looked good for the job. At the beginning of the challenge, before a series of curves, one adjustment of the 8th gear, corresponding to the 1st gear of the high gear, set a speed of 30 to 35 km / h, at the limit of its green belt. , at 2,000 rpm. The arrangement was sufficient to preserve the brake and ensure safety on the slope.

Surprising, however, was the performance of the Turbo Brake, a unique equipment of the brand, offered as an option. It is an auxiliary engine brake that uses part of the combustion gases to drive the engine turbine and increase the braking power, which can reach 580 hp. Just to give you an idea, the also efficient High Brake, another engine brake concept from Mercedes, did not exceed 350 hp. At Serra do Mar, the use of High Brake cooled any surge of the truck, shaken by the sharp gradients of the slope.

The Turbo Brake feature greatly enhances the driver’s ability to adjust, via the dashboard, the braking force without having to step on the brake pedal. Good use of the Turbo Brake also helped to gain advantage in the tank. The section between the heights of São Paulo, along the Rodovia dos Imigrantes, and the slopes of the Serra, to Cubatão, SP, a total of 53 km. In this first stage of the route, the Axor used 14.59 l of fuel, making an average of 3.63 km / l. Excellent results, since during the route it was faced with several periods of heavy rain, increasing the air resistance.

saving power

Once again with full storage, the Axor 2540 was in a good position to convey its skills to maintain the rhythm of the ride. At sea level and the sun is already shining, which gave the drying of the track, the car proved, once again, its mechanical accuracy. The engine was powerful and responded easily to throttle commands, accepting the driver’s wishes without resistance. Getting it up to highway speeds was easy, and maintaining it required no more than a simple push of the cruise control button. The truck manages itself at a speed of 90 kilometers per hour at 1,400 rpm, that is, almost at the beginning of the green range. An important feature, since it did not provide equipment, promoting a direct relationship between economy and durability of the car.

The configuration of the composition revealed another well-known characteristic and left no doubt about the advantages that a trailer assisted by pneumatic suspension brings. It can be said that the mechanical horse was talking to the vessel, without causing many bumps in the cabin and every violation of the floor.

The stage was concluded with a trip between Cubatão, SP, and Peruíbe, SP, which reached 159 km. In it, the Axor “drank” 66.35 l of diesel, making a consumption of 2.39 km / l. Averages that actually tend to improve in a more refined and common partnership between driver and truck.

The last part of the test had the worst of both worlds in store: the steep incline of the Rodovia dos Imigrantes, a watercourse between trucks, as power is expected to be able to maintain a speed advantage and reduce gear changes. The Axor did not disappoint, although it should not be forgotten that it was traveling with 16,620 kg less than it could have. Conditions dictated the use of a simple 4th gear so as not to overshift. Therefore, the model traveled at a speed of 40 km / h with the tachometer pointer at 1,400 rpm. It is very reasonable for the slope of the track, which, sometimes, reaches 8%. The route collected 50 km and the car used 41.83 l, resulting in 1.19 km / h. At first glance, it may seem excessive, but calculating the entire cycle, the heavy Mercedes-Benz model made an average of 2.13 km / l, because in 262 km it ran, it consumed 122.76 km / l. It’s not a surprising result, but it’s definitely among the indices that present benefits to businesses.
