Testing is scheduled to start on an electrified truck with a conventional Allison transmission in early 2022, ahead of the vehicle’s competition debut at the Dakar Rally in January 2023.
Gerard de Rooy, managing director of De Rooy Transport and owner of the truck rally team, Team De Rooy, said: “Dakar and other rally raids are really tough on mechanical components, especially the suspension, axles and gearbox. On hard surfaces, severe vibrations go through the whole driveline and consequently through the entire rally truck, hour after hour, causing damage. On loose sand, traditional clutch-operated transmissions limit traction at low speeds. That’s why our team switched in 2018 to an Allison fully automatic transmission. Knowing how effective and robust Allison’s transmissions are, it is great to have the company’s support with our plans to go electric.”
Team de Rooy’s new IVECO electrified truck will use Allison’s 4000 Series fully automatic transmission with retarder, suitable for medium- and heavy-duty commercial engines (and electric motors).
One of the advantages of Allison transmissions is the company’s patented torque converter, which multiplies torque at launch. This will enable Team de Rooy’s electric rally raid truck to utilise a smaller and less powerful drive motor to optimise range and efficiency, and to perform well when powering up sand dunes. Another advantage is the dampening effect of the fluid coupling in the converter, which helps protect the truck’s drive motor from shock loading associated with torsional forces in the driveline. A further benefit is made possible by self-learning algorithms in Allison Automatics, which continually optimise engine speed and torque level. This helps maximise efficiency and minimise energy use in electric motors, according to Allison.
While the new electric truck is under development, Team de Rooy will enter the 2022 Dakar Rally with diesel-powered IVECO trucks equipped with Allison fully automatic transmissions, supplied and supported by Drive Line Systems (DLS), the official Allison Authorised distributor for the Netherlands, Belgium, Luxemburg, Iceland and Turkey.
