Difficult first laps for the Alpenglow hydrogen-powered Alpine

Unveiled on the Spa-Francorchamps circuit on May 10, 2024, the Alpine Alpenglow demonstrator was scheduled to make its first dynamic public outing the next day. Electronic problems decided otherwise, even if the hydrogen system was not to blame.

Presented in 2022 in the form of a concept car, the Alpine Alpenglow handed over to a rolling demonstrator, Alpenglow Hy4, which was to make its first laps as part of the 6 Hours of Spa-Francorchamps. Electronic problems did not allow the vehicle to start, but this is not a problem related to the 340 hp 4-cylinder internal combustion engine supporting high pressures for hydrogen combustion. Its two pontoon tanks are positioned on either side of the passenger compartment and enhance the stylistic work in the service of teardrop aerodynamics. In its final version, the vehicle will benefit from a V6 which has received a specific development as part of the 24 Hours of Le Mans program.

Alpine increases research into materials

The Alpenglow programme represents a laboratory for Alpine, the Renault group’s sports brand, which is studying several energy solutions for its future models, electric (BEV), hydrogen fuel cell (FCEV), synthetic fuels, etc. Alpine also allows research on materials, in particular carbon fibre, which contributes to the featherweight of the Alpenglow. Carbon which is also found on the rims, which have been particularly carefully looked after by the Alpine design teams.

Let’s recall that with the 100% electric A110 E-ternité prototype, Alpine explored the potential of flax fibre. Several important bodywork elements, such as the skin of the hood, roof, rear window, grille, seat shells and rear skirt, were supplied by the Norman company Terre de Lin, located nearby from Dieppe, the cradle of the brand. “As strong as carbon-fibre and with better acoustics, flax is a promising material. This new experience also allows us to prepare for the future. Indeed, the design of the parts is today compatible with different composite materials, which allows the same mold to be produced in carbon, glass or flax fibre composite without distinction,” emphasised an Alpine spokesperson.

For the Alpenglow Hy4, the next meeting is set for the legendary 24 Hours of Le Mans circuit, on June 15 and 16, 2024. With its first public laps!
