Introducing the Alpine Alpenglow Hy6: A Hydrogen Revolution with V6 Power

Alpine’s latest creation, the Alpenglow Hy6, marks a bold move in automotive innovation with its 3.5-litre, 6-cylinder hydrogen engine. Furthermore, by building on Alpine’s heritage and environmental vision, this concept seamlessly combines cutting-edge hydrogen technology with high-octane power. Let’s take an in-depth look at how Alpine is, once again, reimagining the future of sustainable performance.

1. A New Dawn for Alpine

Alpine first unveiled the Alpenglow concept in 2022, setting a blueprint for its vision of sustainable performance. Therefore, the Alpenglow Hy6 now arrives as the next stage in this evolution, boasting Alpine’s first hydrogen-powered V6 engine.

• Engine: 3.5-litre, 6-cylinder hydrogen combustion
• Power: 740 bhp, providing a dramatic performance boost
• Emissions: Carbon-free through hydrogen combustion

Alpine named this groundbreaking car Alpenglow to evoke the dawn, mirroring its goal to lead a new era of motorsport with reduced environmental impact.

2. The Power Within: Hydrogen V6 Engine

Under the hood, the Alpenglow Hy6 features a 3.5-litre V6 engine developed specifically for hydrogen combustion. With a staggering output of 740 bhp, it more than doubles the power of its 4-cylinder predecessor. This engine brings hydrogen fuel into the high-performance realm, marking a significant leap in Alpine’s sustainable innovation.

Engine Highlights:

• Capacity: 3.5-litre V6, open at 100 degrees
• Supercharged: Twin turbochargers for extra punch
• Top Speed: Over 330 km/h, reflecting the track-inspired performance
• Efficiency: Indirect water injection to keep emissions low

To achieve maximum power, Alpine used methods from Formula 1 engine development, ensuring every detail of the hydrogen combustion process met their rigorous standards.

3. A Sound to Thrill: Engineering the Roar

Alpine engineers were meticulous about the sound of the Hy6 engine. Unlike electric vehicles, this hydrogen-powered car produces an impressive exhaust note, hitting high revs at 9,000 rpm. Thanks to a custom Inconel exhaust system, the Alpenglow Hy6 combines high performance with the unique sound profile drivers expect from an Alpine.

• Rev Limit: 9,000 rpm
• Exhaust System: Inconel, specifically tuned for an evocative sound
• Acoustics: Balances a powerful roar with smooth hydrogen combustion

This sound signature sets the Alpenglow Hy6 apart in the push toward greener motorsport. It’s about creating an experience.

4. Design Innovation: Shaping Aerodynamics with Hydrogen in Mind

The Alpenglow Hy6’s exterior design is shaped by aerodynamics to complement the powerful hydrogen engine. In addition, Alpine’s design team worked to integrate elements that balance efficiency with aesthetics.

Key Design Features:

• Body Material: Specular Blue all-carbon body for strength and lightness
• Rear Window: Iconic design inspired by the Alpine A110, featuring transparent NACA ducts for cooling
• Rear Wing: Transparent, aggressive design made from lightweight materials

Alpine’s design team took inspiration from the A110 for elements like the rear window, which now includes transparent NACA air intakes. Consequently, these cooling channels lead directly to the gearbox, thus ensuring optimal performance.

5. Interior Craftsmanship: Comfort Meets Technology

The Alpenglow Hy6 interior seamlessly combines Alpine’s racing heritage with modern technology. When you step inside, you’ll immediately find a space designed for driver focus and passenger comfort. Additionally, the sleek design draws inspiration from the brand’s rich history in motorsport, creating an environment that is both functional and stylish.

Interior Features:

• Door Design: Elytra-style doors for ease of entry and dramatic effect
• Seats: Custom bucket seats with light-reactive fabric in metallic blue tones
• Dashboard: Magenta crossbar and carbon fibre detailing, echoing an aircraft aesthetic

The Alpenglow Hy6’s cockpit triangle – Alpine’s signature interior feature – serves both function and form, displaying real-time information like G-force and engine speed.

6. Safety First: Hydrogen Storage and Handling

To bring hydrogen power to motorsport, safety is paramount. With this in mind, Alpine designed the Alpenglow Hy6 with three high-pressure hydrogen tanks, each storing 2.1 kg of hydrogen. Furthermore, Alpine’s meticulous approach to safety includes a pressure regulator, hydrogen sensors, and a colour-coded alert system.

Hydrogen Storage:

• Tanks: 3 x 2.1 kg, with 700-bar pressure capacity
• Safety Measures: Rapid fuel evacuation valves, hydrogen sensors
• Alert System: Colour-coded indicators for both driver and emergency services

The entire system adheres to European Regulation 134 for hydrogen vehicle safety, with several redundancies in place to prevent and mitigate potential hazards.

7. Hydrogen Combustion in Racing: Why It’s the Next Big Thing

Alpine has made a bold choice with hydrogen combustion over fuel cells, as it cites the feel, power, and sound of a combustion engine as essential to the Alpine racing experience. Furthermore, this approach provides high performance, rapid heat dissipation, and a more satisfying driver experience, thanks to the intense power output and responsive performance.

Benefits of Hydrogen Combustion:

• Driving Experience: Traditional engine feel and sound
• Performance: Excellent under high load
• Cooling Needs: Reduced, as more heat is expelled through exhaust

Alpine believes that hydrogen combustion is better suited for motorsport, where driver engagement and instant power are crucial.

Technical Specifications of the Alpine Alpenglow Hy6:

• Width: 2.10 metres
• Length: 5.20 metres
• Height: 1.14 metres
• Fuel Type: Hydrogen, stored in 3 x 2.1 kg tanks at 700 bars
• Engine Architecture: 100-degree V6 with twin turbochargers
• Displacement: 3.5 litres
• Max Power: 740 bhp at 7,600 rpm
• Top Speed: Over 330 km/h (205 mph)

The Future of Hydrogen in Motorsport

The Alpenglow Hy6 showcases Alpine’s commitment to making hydrogen combustion a viable alternative for high-performance motorsport. Moreover, this approach aligns with the goals of the ACO and FIA, who plan to allow hydrogen-powered cars in events like Le Mans 2028.

• Alpine’s Vision: Develop liquid hydrogen technology for improved integration and faster refuelling
• Environmental Goal: Provide a sustainable, thrilling motorsport experience
• Long-Term Plans: Continue to adapt to evolving regulations for hydrogen use in competitive racing
