2024 Porsche Taycan Turbo S!
Alpine’s Alpenglow Hy4 is a car that runs on hydrogen and has a turbocharged 2.0-liter engine, which delivers 340 horsepower. The engine has three hydrogen tanks that hold 4.6 pounds of hydrogen each, at 700 bars of pressure. Alpine is currently developing a new V-6 engine for hydrogen applications, which suggests that a new Alpenglow variant, possibly named Hy6, is on the horizon. The Hy4’s design has been modified to include a two-seat cabin and hydrogen tanks embedded inside pods.
The car also has an updated aero package with a taller stance and a new roof scoop for better aerodynamics. Alpine believes that the hydrogen powertrain technology in the Hy4 could be used in street-legal models in the future. The idea of using hydrogen to power internal combustion engines is not new and has been experimented with in the past, such as BMW’s experiments in the late 1970s and 2000s.
