Alpine has unveiled the updated version of its Alpenglow concept car, now named the Alpenglow Hy6, which features a powerful hydrogen-combustion engine. This concept, initially introduced in 2022, highlights Alpine's dedication to sustainable high-performance vehicles and potential future motorsport applications. The Alpenglow Hy6 is equipped with a specially developed 3.5-liter V6 hydrogen combustion engine that generates an impressive 740 bhp, showcasing a significant increase in power compared to its previous 4-cylinder version. The engine's capacity to rev up to 9,000 rpm allows the concept to achieve a top speed exceeding 330 km/h. Alpine's VP of Motorsports, Bruno Famin, emphasized the company's commitment to hydrogen research and its potential for high-performance motorsport applications. The concept's design has been updated to accommodate the new powertrain, featuring a redesigned rear section that showcases the hydrogen engine through blue-tinted glass. Safety measures such as Regulation 134 certified composite cylinders and rapid fuel evacuation valves ensure safe usage of the three hydrogen tanks onboard. Alpine's decision to opt for a hydrogen combustion engine over a fuel cell system aims to retain the traditional race car driving experience while reducing carbon emissions. Additionally, the company is exploring liquid hydrogen storage solutions for enhanced integration and quicker refueling. This development aligns with future motorsport regulations, with the ACO and FIA planning to allow hydrogen-powered cars in the 24 Hours of Le Mans from 2028. The Alpenglow Hy6 symbolizes Alpine's vision for sustainable high-performance vehicles and showcases their innovative approach to addressing future automotive challenges.
