JCB Dieselmax, the story of the fastest diesel car in history

A diesel car faster than a Bugatti Chiron? It exists, but it is not a hypercar like all the “others”. There JCB Dieselmax it is a unique example in the world and its shape is more reminiscent of a missile than a real car.

Designed to reach 560 km / h, this strange prototype holds the record of fastest diesel car in the world.

A missile gives 1,500 CV

The project was launched in 2006 and involved a vehicle powered by two 5.0-liter 4-cylinder engines of 750 HP each and placed one at the front and one at the rear. Each engine had a limited speed of 3,800 rpm and was complete with turbocharger, intercooler and aftercooler.

Although by modern standards the overall power of 1,500hp may seem “normal” (for example, the Chiron has 1,600hp, the Hennessey Venom F5 over 1,800hp and the electric Rimac Nevera 1,914hp), it was the sophisticated aerodynamics to make JCB special.

The Dieselmax, in fact, could boast an aerodynamic coefficient of 0.147, far lower than the 0.20 of the Mercedes EQS, one of the production cars with the lowest Cx in the world and presented only 15 years later.

The long road to the record

The first test “on the road” of the Dieselmax was held on July 30, 2006, when the car reached 320 km / h. Over the next few days, the engineering team put the JCB through its paces to over 400km / h. Then, on August 13, came the official debut at the Bonneville Salt Flats, Utah Speed ​​Week event. Here, the Dieselmax hit 510 km / h.

Do not pay for the result, the designers went back to work noting some changes to the set-up. Thus, on August 23, 2006, JCB made history by stopping the speedometer at 563.418 km/h.

Incidentally, according to the engineers, the car could have reached even higher speeds, but some tire problems limited its potential. The fastest diesel car project in the world, however, was shelved due to lack of additional funds and we will hardly see it again attempting a record in the near future.
