Alpine has launched the Alpenglow Hy6, the first car to feature the innovative hydrogen-powered V6 engine, accelerating the development of sustainable high-performance racing.
Initially showcased in 2022 as a concept car, the Alpenglow has now evolved into its most advanced form and will return as a prototype at the Paris Motor Show in 2024.
At this year's 24 Hours of Le Mans, the latest model impressed with an output of an astounding 730 horsepower, more than double the output of its previous four-cylinder engines.
What makes the Alpenglow Hy6 so special?
One might wonder, what is so special about the Alpenglow Hy6? The car employs a 3.5-liter twin-turbocharged V6 engine, co-developed with the French racing team and manufacturer ORECA. This engine, powered by hydrogen, combines the raw power of a gasoline engine with more environmentally friendly technology.
When it comes to hydrogen-powered vehicles, one might think of fuel cells. Unlike internal combustion engines, hydrogen fuel cells generate electricity through a chemical process, meaning they also require batteries and electric motors, similar to hybrid vehicles.
However, what sets the Hy6 apart is that it provides similar emission reductions using hydrogen fuel while retaining the familiar and beloved form of an internal combustion engine (ICE).
Moreover, the Alpenglow Hy6 is more than just a concept; it represents a glimpse into how hydrogen engines could shape the future of racing. The new engine not only delivers 730 horsepower at 7,600 rpm and 570 lb-ft of torque at 5,000 rpm, but also surpasses the per-liter power of Alpine's newly introduced exclusive gasoline engine, the A110 R Ultime.
Notably, Alpine's top speed exceeds 330 km/h, and the company is betting on hydrogen power systems to be competitive in racing soon, especially as global regulations continue shifting towards greener technology.
Alpine is focusing on the potential of hydrogen on the racetrack and beyond, laying the groundwork for a broader spectrum of sustainable high-performance vehicles.
"Nearly Zero-Emission" Powertrain Systems
While hydrogen engines are often touted as "clean," they are not completely emission-free. The combustion of hydrogen does indeed produce nearly zero CO2 emissions.
However, there is an issue: nitrogen oxides (NOx), a byproduct of the combustion process, are still released into the atmosphere. Thus, although this technology represents a significant advance, it is not entirely pollution-free.
Conclusion
As for concept cars, it remains uncertain when or how we might see this technology applied in the real world.
Nonetheless, it is hoped that in the near future, we will see more hydrogen-powered race cars on the tracks, as ACO and FIA authorize the use of hydrogen vehicles in future races.
