Originally introduced in pure concept form at the 2022 Paris Motor Show, French automaker Alpine apparently has some serious plans for the Alpenglow hypercar. A running version, dubbed the Alpine Alpenglow Hy4 is set to take to the track for the 6-hour Spa-Francochamps endurance race this weekend. What stands out is not just the exotic design and impressive performance but the fact that the Hy4 uses a hydrogen-powered internal combustion engine.
