Hydrogen Hilux: British-built prototypes attain last growth part


The debut of our totally functioning hydrogen Hilux prototype in September 2023 demonstrated the breadth of applied sciences Toyota is making use of in its progress in the direction of carbon-free mobility. Now we’re delighted to report that this ground-breaking challenge has moved into its last part of growth.

Ten gas cell Hilux prototypes have been constructed on the Toyota Motor Manufacturing UK (TMUK) facility in Burnaston, Derbyshire. 5 will endure rigorous subject testing to evaluate security, efficiency, performance and sturdiness, producing take a look at drive information in real-world conditions. The opposite 5 are destined for buyer and media demonstrations, together with on the Olympic and Paralympic Video games Paris 2024.

Know-how gained from the Hilux challenge will mix with Toyota’s 30 years of hydrogen gas cell growth and contribute to the following technology of gas cell know-how.

Hydrogen Hilux: car profile

The hydrogen Hilux showcases how gas cell know-how could be built-in right into a pick-up. Externally, it’s the similar dimension as an everyday Hilux with an additional cab physique. However beneath the floor, the chassis integrates core components from the Toyota Mirai hydrogen gas cell electrical saloon – know-how that has proved its high quality in nearly ten years of business manufacturing.

Hydrogen is saved in three high-pressure gas tanks mounted inside the car’s ladder body chassis. Every tank comprises 2.6kg of liquid hydrogen to provide a complete capability of seven.8kg, which is sufficient to provide an anticipated driving vary of as much as 373 miles. The polymer electrolyte gas cell stack comprises 330 cells and is mounted above the entrance axle. A lithium-ion battery within the rear load deck shops the electrical energy produced by the gas cell, which in flip powers a 134kW (180bhp) and 300Nm e-motor on the rear axle. When pushed, the gas cell produces no tailpipe emissions apart from pure water.

Mission historical past

The hydrogen Hilux challenge started in early 2022 with a feasibility research undertaken by TMUK and Toyota Motor Europe with consortium companions Ricardo, European Thermodyamics, D2H Superior Applied sciences and Thatcham Analysis. Funding was subsequently gained from the UK authorities facilitated by the Superior Propulsion Centre. Extra assist was additionally offered by Toyota Motor Company.

An intense design and growth programme commenced in July 2022. Nevertheless it wasn’t till June 2023 that development of the prototype truly started, with work happening in a devoted space inside TMUK’s Burnaston facility. Utilizing environment friendly Toyota Manufacturing System ideas, the primary car was accomplished simply three weeks later. The 9 further autos had been constructed by December 2023.

What is going to next-generation hydrogen know-how appear to be?

Toyota’s industry-leading analysis and growth in hydrogen gas cell know-how led to the launch of the unique Mirai in 2015. 5 years later, the next-generation Mirai launched second-generation know-how, which prolonged the automotive’s driving vary by 30% to round 400 miles. It’s this know-how that underpins the hydrogen Hilux.

Nevertheless, third-generation gas cell know-how is presently beneath growth. It represents a key component in Toyota’s plan for increasing hydrogen utilization, with gross sales scheduled to begin in 2026-27. These items can have a better energy density and allow an anticipated 20% enhance in car driving vary, whereas technical advances and elevated manufacturing volumes might assist to cut back prices by multiple third.

Analysis can be progressing on the potential of making scaleable gas cell stacks with completely different energy outputs. Toyota engineers are additionally making gas tanks with shapes extra complicated than the prevailing cylinders, which can make the know-how extra suitable with completely different dimension autos.
