2025 Toyota GR LH2 Racing Concept

By Team Dailyrevs June 12, 2025

Toyota debuts the GR LH2 Racing Concept at Le Mans with a hydrogen combustion engine and hybrid assist.
Based on the GR010 Hypercar chassis, it runs liquid hydrogen stored cryogenically.
It’s not a design study — it’s being tested for real on-track use.

Hydrogen and Hybrid: A New Racing Equation

The 2025 Toyota GR LH2 Racing Concept isn’t just an aero-sculpted concept car parked under lights — it’s a statement from Toyota that hydrogen combustion might still have a future in top-tier motorsport. Based on the same chassis as the GR010 Hypercar, this one ditches traditional fuel for liquid hydrogen, stored in cryogenic tanks and burned in a modified engine backed by hybrid electric drive.

Toyota hasn’t dropped full output figures yet, but given the GR010’s 680 PS setup, expectations are high that this concept is within striking distance. More importantly, it’s functional. This isn’t a static model. The company says it’s been testing the GR LH2 under real conditions.

Stance, Surfaces, and Serious Intent

At a glance, the GR LH2 looks like it belongs on a Le Mans grid tomorrow. It stretches 5,100 mm in length and 2,050 mm in width—similar to the GR010—but there’s a leaner, more focused visual attitude to it. The front overhang is tight. Side aero channels are deeply scalloped. And the roofline is drawn down, almost GT-like.

But it’s the proportions that lock it in. That long, flat midsection and tall rear wing tell you this thing was built for speed and balance, not just design drama. Every line seems to be there for aerodynamic flow — not flourish.

A Continuation of Toyota’s Hydrogen Campaign

Toyota's been building its hydrogen credibility bit by bit. There was the GR Corolla H2, then the GR H2 Racing Concept, both running gaseous hydrogen. The move to liquid hydrogen now — which is more energy-dense but way trickier to manage — shows just how serious Toyota is getting.

What’s changed is that this LH2 concept runs with hybrid electric torque, likely offering a more predictable power band for racing. It’s early days, but Le Mans organizers are pushing toward hydrogen-powered entries by 2027, and Toyota wants to be ready before the flag drops.

The Big Reveal at Le Mans

The LH2 concept made its debut during Le Mans week, alongside a throwback-liveried GR010 and a stealthy matte-black sibling. The setting wasn’t random. The H2 Village at the Circuit de la Sarthe served as a fitting stage for what Toyota describes as “a near-future machine.”

There’s no timeline yet for race entry, but engineers say it’s not just vaporware. It’s already being put through its paces.

Why It Matters

The 2025 Toyota GR LH2 Racing Concept isn’t looking for headlines — it’s looking for answers. It’s the latest proof point in Toyota’s argument that hydrogen combustion, especially when mixed with hybrid tech, could be part of motorsport’s next chapter. Quietly, steadily, they’re making their case.
