• Alpenglow Hy4 is a fully working hydrogen prototype based on Alpine’s 2022 concept.
  • Debuts at Spa this weekend, where it will performance demonstration runs before reappearing at Le Mans in June.
  • Rolling lab’s 335 hp inline four will be upgraded to a V6 for a second prototype that’ll be revealed later this year.

Renault thinks hydrogen will play a major role in tomorrow’s car market and it’s turned its 2022 Alpenglow concept into a fully drivable Alpenglow Hy4 prototype to prove how serious it is about the fuel.

Now offering seating for two, instead of just one, the subtly reworked supercar will make its debut at the Spa 6 Hours this weekend, where it’ll run demonstration laps, before doing the same thing at Le Mans in June.

Despite what the hypercar styling and fancy carbon chassis might suggest, the Hy4 only makes 335 hp (340 PS) from a 2.0-liter, turbocharged four-cylinder engine, but Alpine says that’ll be upgraded to a V6 – again, fueled by hydrogen – when a second iteration of the prototype is revealed at the back end of the year.

This is a developing story and will be updated.
