Enhanced Performance with the Hy6 Engine

Building upon the initial road-going prototype powered by a 340 bhp, turbocharged 2.0-litre 4-cylinder engine, the Alpenglow Hy6 is equipped with an innovative 3.5-litre V6 engine that delivers over twice the power output. Developed exclusively by Alpine for hydrogen combustion, this groundbreaking engine produces 544 kW (740 bhp) and achieves an impressive 150 kW/l (210 bhp/l), ensuring exceptional performance aligned with the striking design of this rolling laboratory.

Exterior Design Features

The 2024 Alpine Alpenglow Hy6 has evolved significantly since its inception, thanks to a collaborative effort between designers and engineers focused on merging aerodynamic efficiency with aesthetic appeal. The all-carbon bodywork, rendered in Specular Blue, features extreme design modifications that enhance both performance and visual impact.

The new V6 engine is a prominent feature, displayed behind a tinted glass cover that allows for a clear view of its engineering marvel. The rear window's iconic shape, reminiscent of the A110, incorporates two transparent NACA air intakes that channel air to the gearbox oil cooler, enhancing the car's overall lightness. The plenum (air intake manifold) features the Hy6 logo, echoing the style of cylinder head covers seen in classic racing cars.

Additional air intakes with three louvres ensure proper cooling for this powerful engine, while the removal of the rear wing bridge allows for a floating design, further emphasizing the engine's visibility. The rear wing maintains a transparent aesthetic for improved visual lightness but adopts a more aggressive racing style, supported by aluminum struts.

Interior Design Innovations

The 2024 Alpine Alpenglow Hy6 features elytra-shaped doors that facilitate easy access, allowing occupants to slide over the angled sidepods into precisely adjusted bucket seats. The upholstery utilizes a new fabric that reacts to light, presenting metallic and blue hues.

The distinctive triangle at the front of the cockpit, a hallmark of Alpine design, provides vital visual cues for the driver, changing color to convey real-time data such as lateral G-forces and engine speed. The dashboard includes a magenta tubular crossbar, with materials such as carbon fiber and aluminum accentuated by Alcantara upholstery featuring 3D-printed motifs. The layout incorporates dedicated slots for mounting mini-action cameras, enabling the recording of the Alpine Alpenglow Hy6's track performances.

Innovative Hy6 V6 Engine Technology

The Alpine Alpenglow Hy6 prototype is engineered as a competitive race car, constructed on a lightweight LMP3 carbon chassis designed to maximize the potential of the new Hy6 V6 engine. This 3.5-litre V6, developed from scratch by Alpine, represents a significant engineering achievement in hydrogen combustion technology.

The Hy6 V6 features a 100° open design, supercharged by dual turbochargers, and is constructed with a solid aluminum engine block and a dry sump. Key features include an optimized cooling circuit, chain-driven overhead camshafts, and a high-revving nature that peaks at 9,000 rpm, producing 740 bhp at 7,600 rpm, enabling top speeds exceeding 330 km/h.

Safety Measures for Hydrogen Technology

The Alpine Alpenglow Hy6 employs rigorous safety measures for its hydrogen storage and delivery systems. The vehicle features three high-pressure hydrogen tanks, each capable of storing 2.1 kg of hydrogen at 700 bars, strategically placed in ventilated compartments to enhance safety. A comprehensive safety protocol includes rapid fuel evacuation valves, hydrogen presence sensors, and a color-coded system to alert drivers and emergency services to various incident scenarios.

The Future of Hydrogen Propulsion in Motorsports

Alpine’s commitment to hydrogen-powered propulsion centers on utilizing internal combustion engines, which retain the exhilarating driving experience synonymous with racing. This approach benefits from high power output and reduced cooling requirements, making it ideal for motorsport applications.

As Alpine advances its research and development, the company is at the forefront of exploring liquid hydrogen solutions for efficient fuel integration and rapid refueling capabilities. With plans for the ACO and FIA to permit hydrogen-powered cars in the 2028 24 Hours of Le Mans, Alpine is well-positioned to lead in the hydrogen racing category.
