At the 2022 Paris Motor Show, Alpine presented its Alpenglow concept, embodying the brand’s ongoing research into hydrogen-powered combustion engines for sports cars, with the potential for high performance both on the road and in competition, in line with the brand’s decarbonization targets.

Alpine has now presented the Alpine Alpenglow Hy4 no longer just a concept car but as a rolling lab designed as a racing car with its carbon monocoque and a turbocharged 2.0-liter 4-cylinder engine developing 340 hp.

The 4-cylinder development engine marks 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.

Alpine Alpenglow Hy4 is making its public debut today before the TotalEnergies 6 Hours of Spa-Francorchamps Endurance Race (FIA WEC) and its 70,000-plus spectators. Alpine Alpenglow Hy4 will also make demonstration runs during the 92nd edition of the 24 Hours of Le Mans on 14 and 15 June 2024.

As part of our active participation in decarbonizing motorsports, we see the hydrogen internal combustion engine as an extremely promising solution. We know that hydrogen will be an essential step in decarbonising the next generations of Endurance cars, and could also be for Formula 1 cars, particularly by switching to liquid storage for greater compactness and performance. The Alpenglow prototype perfectly illustrates this, a genuine technological laboratory for developing tomorrow’s hydrogen engines.

The hydrogen solution is being considered in various ways throughout the Renault Group, contributing to its carbon neutrality objectives in Europe by 2040 and worldwide by 2050.

With HYVIA (a joint venture with Plug), Renault Group offers a complete ecosystem that includes fuel cell-powered light commercial vehicles, hydrogen recharging stations, fleet financing, and maintenance services. Renault Group is also developing hydrogen combustion engines for high-powered extra-urban commercial use and specific sportier purposes.

The Renault brand is also developing a hybrid technology that combines an electric motor with a hydrogen range extender powered by a fuel cell.

Alpine firmly believes in the role of motorsport as an accelerator for the development of future mobility technologies. The hydrogen-powered internal combustion engine is a tremendously promising solution for racing and road use, the company says. Alongside the rolling hydrogen version of Alpenglow, Alpine is gearing up for the launch of seven new electric models between now and 2030, starting this year with the A290, its sporty city car and the first electric model from the Alpine Dream Garage.
