The Fastest Truck of the 1950s with a Special Purpose… ▶ Willeme-Michelin WR8 Story

To achieve prominence in the world of transportation, it is vital to possess qualities that contribute to advances in

truck

design or technology. These qualities can range from design performance and load capacity to comfort, safety and versatility. Historically, technologies that meet these requirements have been key for a

in France just after the end of During the First World War, the Willm company began its operations by repairing military trucks that were left as remains of the recent conflict, however, after

special

izing in this task, the company began to experiment with the production of various models and

special

ized trucks for the transportation of large and extra-heavy loads.

Their experience allowed them in the late

1950s

to be tasked with developing a unique production truck that required a very peculiar design due to the nature of the tasks for which it was to be specifically built. This was commissioned by the tire manufacturer Michelin, who proposed a series of special requirements for the development of the unit so that it could function as a kind of tire tester. Although it may seem absurd, one of the main requirements was to be able to transport loads normally when It's supposed to be what any transport truck should offer you. It is important to note that since it was a unit designed to be a tire tester, the priority over its load capacities was to take the tires to the limit by subjecting them to high speeds and variable stress conditions, and it was expected that the truck would have improved. aerodynamics to help it easily overcome the 100 kmph barrier, something that would truly become a feat for any truck in the

1950s

because of this, the cabin design resembles the shape of an airplane cabin to achieve the maximum aerodynamic coefficient by giving it a peculiar and unique appearance as a result, the French company designed the truck that would be officially called Willam Michelin wr8 type LD 910.

It featured a long, narrow hood without fenders and a sealed inclined cabin that was built by another French company called Teal Hall, interestingly to accelerate. In the production of this truck, some automobile parts were used, highlighting the use of the windshield from a Citroën DS. Its body construction, which was much narrower than usual, was made primarily of steel bars, ensuring it was of adequate weight without sacrificing vital load capacity. Additionally, there was enough space in its cabin for an engineer to accompany the driver and analyze all the performance data of both the truck and the tires, according to the company.

The mechanical specifications included an 18 L inline 8-cylinder gasoline engine coupled to a six-speed manual transmission. transmission, it is important to keep in mind that gasoline was preferred over diesel since the main objective was to reach high speeds. This combination generated a power output of 240 horsepower, allowing the truck to reach an incredible speed of 50 kmph without any problems. This configuration allowed for tire evaluation. Under various conditions and stress situations, the truck also known simply as willm wr8 facilitated testing at different speeds and with various loads, allowing the response and performance of Michelin's heavy truck tire compounds to be evaluated, becoming a unique vehicle and true engineering.

A wonder of its time, the truck remained in service for a couple of decades, during this period it is said to have covered several thousand kilometers on the Michelin test track in Leo, in the Clermont Fon region of France, after this period the company decided to retire, which was also caused by the appearance of another similar but more advanced unit, although this truck remained in apparent obscurity since its useful life ended, Michel unfortunately decided to undertake a complete restoration process in 2005, the objective was to restore it in perfect operating conditions to participate in various automotive industry events. throughout Europe mainly due to the importance it achieved, curiously the idea of ​​​​using vehicles to test tires did not fade away when Michelin withdrew the WR WR8, but rather its departure from the test tracks was simply to make way for a new model that was had been developing for quite some time.

At some point, this new model known as the Michelin plr managed to make a similar, if not greater, impact due to its extremely unusual design. The most distinctive feature was the Imp implementation of five axles, three driven and two directional with a general structure based on a luxury Citroën. DS vehicle Additionally, this vehicle incorporated two Chevrolet V8 engines of 350 horsepower each from the Corvette model, requiring a cooling system with five radiators; however, the most notable thing was that this vehicle was essentially a rolling laboratory since it had a mechanism that allowed subjecting the tires to constant pressure but between 2 and 3.5 tons without necessarily carrying a load and at the same time recording all the data through high-precision measuring instruments.

Unfortunately, the concept of mobile tire testing equipment eventually became unviable due to the oil crises that made them impractical and the emergence of static solutions that achieve equally good results with fewer risks and complications.
