Alpine Alpenglow Hy6: A Hydrogen-Powered Supercar

Alpine, the French automaker known for its high-performance cars, has unveiled the third and most powerful iteration of its hydrogen-powered concept supercar, the Alpenglow Hy6. After three years of refining its hydrogen technology, this latest version features a twin-turbocharged V-6 engine that produces a jaw-dropping 730 horsepower while being completely emissions-free.

Since its debut at the 2022 Paris Motor Show, the Alpenglow has undergone significant upgrades, particularly under the hood. The most recent model is powered by a new 3.5-liter twin-turbo V-6 engine, replacing the 2.0-liter turbocharged inline-four found in previous iterations. This hydrogen-powered V-6, developed over two years, now generates 568 lb-ft of torque and reaches a redline of 9,000 rpm, making it far more powerful than its predecessor. The Alpenglow Hy6 is expected to hit a top speed of 205 mph, thanks to the improved engine performance.

While the exterior design of the Alpenglow Hy6 remains largely unchanged from its earlier versions, it continues to capture attention with its futuristic, Le Mans-inspired aesthetics. The supercar features a bubble-like cockpit, aggressive aerodynamics, and dramatic lighting, giving it a bold, distinctive appearance. A new standout feature is the transparent bonnet, which provides a clear view of the powerful V-6 engine—a nod to Alpine’s focus on showcasing the innovative hydrogen powertrain.

What sets the Alpenglow Hy6 apart from conventional supercars is its hydrogen-fueled engine. The car is equipped with three hydrogen tanks, each holding 2.1 kg of gaseous hydrogen. These tanks feed the mid-mounted V-6, allowing the car to operate with zero harmful emissions while still delivering a high-performance driving experience. The exhaust system, integrated into the taillights, releases only water vapor as a byproduct, aligning with Alpine’s vision for a more sustainable future.

The Alpenglow Hy6 is a glimpse into the future of hydrogen-powered performance vehicles. Alpine, like Toyota, believes that hydrogen combustion engines could help save the internal combustion engine from obsolescence. However, it remains uncertain whether this supercar will ultimately hit production with a hydrogen engine or transition to a fully electric drivetrain. For now, Alpine is pushing the boundaries of hydrogen technology and preparing for its anticipated U.S. debut in the coming years.
