Alpine's Alpenglow Hydrogen V6 Roars to 9,000 RPM with Water-Only Exhaust
Alpine’s Alpenglow hydrogen-powered V6 prototype revs to 9,000 rpm, delivering about 740 hp and a top speed of 205 mph while emitting only water vapor. The design uses a pre-chamber and regulator for hydrogen at ~700 bar, with compact storage tanks and standard radiators to maintain aero efficiency. Blue energy-recovery brake lights and a transparent acrylic rear spoiler underscore that this car is a mobile lab for testing hydrogen in high-performance applications, suggesting clean-energy ICE viability without heavy battery packs.
