What is the Alpine Alpenglow Hy6? 

The Alpine Alpenglow Hy6 is the third and perhaps the most powerful model in the series of Alpine concepts for hydrogen supercars. The journey commenced at the 2022 Paris Motor Show, when Alpine launched the original Alpenglow as a static design study that suggested an audacious new line of attack for the name. Details of that train were vivid but not specific. 

Then in 2023 an idea became the Alpine Alpenglow Hy6 version of Alpenglow, which eventually changed its name to the Alpenglow Hy4, a “rolling laboratory” that evolved a turbocharged 2.0-liter four-cylinder hydrogen engine into a 2.0-liter turbo with around 340 horsepower. It came to life dynamically at the 6 Hours of Spa-Francorchamps dynamically with hydrogen combustion on the spot in 2023, confirming hydrogen combustion was no corporate-room buzzword, showing hydrogen combustion wasn’t just a boardroom razzle-dazzle.

Fast forward to October 2024: Alpine unveiled the Hy6 at the 2024 Paris show this time around—never mind the fact that the Hy6 went up front in the Paris show and nobody had ever seen it as an understated display like that last time. The modest inline-four in the Hy4 has vanished. Instead, there was an all-new, purpose-made hydrogen V6, that more than doubled its capacity. Alpine didn’t simply refresh the Alpenglow—they transformed it. 

The name itself carries meaning. “Alpenglow” is the optical phenomenon in which mountains appear to glow with ethereal light just short of sunrise — as Alpine puts it, the dawn of a new world. With the Hy6, that metaphor seems earned. 

Alpine Alpenglow Hy6 Concept Engine: The Heart of the Matter. 

So let’s talk about the thing that makes the rest of it possible and that is the Hy6 V6 engine. 

Built through your own efforts at the venerable Renault Viry-Châtillon motorsport skunkworks (the same factory that crunches Alpine’s Formula 1 engines), this twin-turbocharged 3.5-liter V6 is something of a throwback to the way it’s always been made. 

The block is made of solid aluminum with a dry-sump lubrication system. Cylinder heads are cast aluminum with chain-driven overhead camshafts. The exhaust system is made from Inconel – the same exotic alloy used in jet engines and F1 cars – and it’s been specifically tuned to amplify the engine’s naturally operatic sound all the way through to that 9,000-rpm redline.

This means the output number worth noting in depth: 210 hp per liter. For context, that’s in Formula 1. 

Pre-ignition is one of the major engineering hurdles with hydrogen combustion. Hydrogen is highly reactive, and knocking is a perennial problem without proper combustion chamber geometry. That is how Alpine Alpenglow Hy6 engineers solved that problem by creating a chamber that encourages turbulent mixing of fuel and air before the spark to result in a more even burn that wouldn’t allow for premature ignition. 

The result? An engine that produces supercar power, sounds stunning, and exhales nothing but water vapor from the tailpipe. 

Hydrogen Fuel System

The Alpenglow Hy6 has 3 composite tanks containing 2.1 kg of gaseous hydrogen stored at 700 bar. Two tanks are in the side pods, and the third is hidden behind the cockpit. Most importantly, all three are contained in tightly sealed, ventilated compartments completely disconnected from the cabin, a major engineering achievement in safety. It’d also come with rapid evacuation valves and constant hydrogen presence monitoring. 

Alpine Alpenglow Hy6 Horsepower and Performance

The number is nearly absurd for a hydrogen-powered idea. 740 horsepower. 568 lb-ft of torque. 9,000-rpm redline. 205 mph+. 

For context, think of the previous Hy4 prototype, which produced 340 hp, well in line with a concept car. The Hy6 more or less doubled that in two years of development. That’s not incremental progress, that’s a statement. 

The drive is transmitted to the rear wheels with an Xtrac sequential gearbox paired with a centrifugal clutch, in the same way you would get in endurance racing prototypes. Drive behavior is pure motorsport: exact, mechanical: alive. 

Alpine VP of Motorsport Bruno Famin was upfront with the ambition: “A solution for keeping growing the passion for motor racing with so incredibly noble a V6 with phenomenal specific power and a sound to thrill drivers and spectators.” 

Translation: This is not a still, sterile future. This is passion-fueled hydrogen. 

Alpine Alpenglow Hy6 Exterior

The Alpenglow Hy6 hasn’t drastically altered its silhouette since 2022, and exactly that has been the right decision. Its design was already one of a kind. 

But it’s 100 percent carbon fiber made in the whole body in Specular Blue, a color that can shift and lighten under light on the skin and almost look like metal. The profile is ultra-low and aggressively aerodynamic, just 1,020 mm tall (roughly 40 inches). For reference, the Lamborghini Huracán is almost four inches taller. 

A transparent bonnet over the engine bay is new to the Hy6. For instance, instead of concealing the V6 in sheet metal, Alpine enclosed it behind blue-tinted glass to set the powertrain as a visual highlight. It’s a bold design that projects confidence. “We built something so beautiful; we want you to see it.”

Here are additional standout exterior details:

• Butterfly-style elytra doors hinge high for dramatic access. 
• NACA air intakes in the rear window similar to the iconic A110 that feeds the gearbox oil cooler cooling ducts. 
• A shiny and transparent rear wing with the Alpine name and the chemical formula for hydrogen (H₂) emblazoned on it. 
• Aggressive aerodynamic louvres with sculpted bodywork informed by real downforce requirements. 

Every surface has purpose. There is nothing decorative for the heck of it. 

Alpine Alpenglow Hy6 Interior

The cockpit is so driver-focused that it is almost clinical, in the best possible way. 

Access is done through those elytra-shaped butterfly doors, which open wide and let passengers slide straight into precision-adjusted bucket seats stitched into a fabric that changes color and finish with the ambient light, changing between metallic and blue tones. 

The dashboard features a magenta tubular crossbar, an uncommon yet arresting form factor, setting up the automotive environment such that, unlike anything else in its day, it feels futuristic without being fancy. This includes elements of carbon fiber, aluminum, and Alcantara, including 3D-printed decorative motifs. 

Alpine’s signature triangular form is front-mounted at the front of the cockpit. Here, it plays a functional role: The triangle changes color in real time to convey lateral G-forces and engine speed data to the driver. It’s a smarter, heads-up display remade through straight-forward design language. 

Practical racing touches also involve dedicated mounting slots for action cameras, a detail that implies Alpine is already considering how footage from this machine will play out on a circuit.

Alpine Alpenglow Hy6 Price: How Much Does It Cost?

Here’s where the truth hits: The Alpine Alpenglow Hy6 Concept is not for sale, and official retail prices have not yet been officially posted. 

Concept vehicle and rolling research platform, the Alpenglow Hy6 is designed to showcase hydrogen combustion tech, inform future motorsport regulation, and may influence Alpine’s next wave of production supercars. It is not a showroom item. 

That said, Alpine has claimed it is developing a production supercar, it is expected to be electric to come out before the decade-end is up. The Alpenglow’s design DNA and some technology could potentially make its way into that car. 

For now, look at the Hy6 less as a vehicle to buy and more like a sample of performance cars getting their start. The technology will have a price. The concept itself? Priceless. 

Why the Alpine Alpenglow Hy6 Matters

Hydrogen combustion doesn’t create the press-button headlines that battery-electric technology does, but Alpine’s argument for it makes a lot of sense. 

Electric vehicles are great for all sorts of applications, but in motorsports, where long time periods, high heat loads, fast refueling, and raw engagement on the part of drivers are non-negotiable, hydrogen combustion provides what most batteries simply can’t: the sensation and noise of an internal combustion engine, delivered with zero carbon emissions. 

Alpine has its sights set on the 2028 24 Hours of Le Mans, where race engineers are ready to launch a hydrogen class. If the Hy6 is essentially Alpine’s audition tape for that race, the plan is compelling. 

VP Bruno Famin put it succinctly: “The Alpenglow Hy6 concept is the ideal example of how this crucial step in reducing carbon emissions in motorsport can be accomplished.“

Conclusion

The Alpine Alpenglow Hy6 Concept is proof that a zero-emission future must not be staid, silent, or entirely dictated by heavy battery packs. Alpine has singlehandedly given us a new lifeline to the internal combustion engine by engineering a 740 hp tailored twin-turbo V6 that is powered entirely by hydrogen and revs like a dynamo at the eye-watering 9,000 rpm. It meets automotive purists everywhere’s research purpose, demonstrating that sustainable motorsport can preserve the soul, drama, and acoustic perfection that made us fall in love with cars in the first place. 

Whether competing on Le Mans-winning pace or planning a multi-million-dollar next-gen hypercar, the Hy6 is certainly a landmark achievement in the annals of automotive history.
