The hydrogen-powered internal combustion engine prototype Alpine Alpenglow Hy4

The first rolling version of the Alpine Alpenglow Hy4 prototype has been presented at the 6 Hours of Spa-Francorchamps endurance race. It will also make demonstration runs at the 92nd edition of the 24 Hours of Le Mans on 14 and 15 June 2024. Following on from the Alpine Alpenglow concept car presented at the 2022 Paris Motor Show, the Alpine Alpenglow rolling lab Hy4 proves by running on a racetrack that performance and sustainable development are compatible, with the added thrill of the sound of an internal combustion engine.

Its name combines the notion of hydrogen 'Hy' and 'four' for 4 cylinders. Alpine is reconciling environmental innovation and performance through its hydrogen combustion engine technology. This technology offers a new approach to decarbonizing motor racing and a possible avenue for sports cars.

Alpenglow is currently fitted with a 4-cylinder development engine, a working phase before the presentation of an all-new V6 engine specifically designed to be powered by hydrogen, developed entirely by Alpine. It will be unveiled in a second rolling version before the end of the year. The hydrogen-powered Alpine Alpenglow Hy4 prototype further refines its design, like a reference to a future Hypercar, bridging the gap between racing and the road.

It now has a two-seater cockpit and adopts several features synonymous with performance, such as a proper racing steering wheel and new wheel rims evoking a sense of speed.

Its design also reveals many hints of the brand's future stylistic evolution.
