Toyota announced the development of a new Hilux prototype featuring a hydrogen fuel cell powertrain sourced from the second-gen Mirai. Toyota’s first FCEV pickup will be built in the UK in 2023, by a consortium of technical engineering partners, using funds from the UK Government. The project is part of the Advanced Propulsion Center (APC), a government-led initiative for the development of zero-emission vehicles in the UK. The £11.3 million (US$ 13.86) funding will cover the expenses of later-stage R&D, taking the product from the “proof of concept” to the “prototype” stage.
Using a Hilux as a base, the team will
remove the diesel engine and drivetrain, replacing them with a much cleaner
setup. Toyota’s second-gen FCEV system including the fuel cells, the electric
motor, and the hydrogen tanks will be sourced from the Mirai, converting the
Hilux into a zero-emission pickup. Interestingly this option was chosen over
the experimental hydrogen-fueled three-cylinder combustion engine found on
Yaris and Corolla prototypes.
Toyota didn’t announce the specifications
of the Hilux H2, but the in the Mirai the powertrain produces 182 hp and 300 Nm of torque, emitting water from its tailpipe. For
comparison, the 2.8-liter four-cylinder turbodiesel engine in the regular Hilux
produces 201 hp and 500 Nm of torque. We also
expect the Hilux H2 to offer AWD, unlike the Mirai which is RWD-only. As for
the driving range from the three hydrogen tanks, it will most likely be lower
than the 647 km of the Mirai due to the much worse aerodynamics and
the increased weight of the pickup.
For the realization of the Hilux H2,
Toyota Motor Manufacturing will work with other UK-based firms with the help of
a Toyota Motor Europe R&D team. Engineering firm Ricardo will support the
technical integration of the fuel cell components to the ladder-frame chassis
of the pickup, ETL will assist in thermal management solutions, D2H will offer
engineering services in thermodynamics, and Thatcham Research will work on
crash safety and insurance ratings. The Toyota Hilux H2 prototypes will be
built at the Burnaston plant in 2023. According to Toyota, the goal is “to
prepare for small series production” and “investigate an additional application
of the fuel cell technology in a vehicle segment that is key to a number of
industry groups and will help support the sector’s move towards
decarbonization”.
The current eighth-generation Toyota Hilux
is in its twilight years having debuted back in 2015, with two subsequent
facelifts in 2017 and in 2020. The next generation of the popular pickup will
likely bring some sort of electrification into the mix, although an FCEV model
sounds unlikely for mass production due to the limitations in the hydrogen
refueling network. Still, working prototypes of the Hilux H2 sound really cool
and could provide useful insights for the future. Most importantly, the project
will allow the involved parties to develop their expertise in FCEV technology
and vehicle conversion.
