Alpine has unveiled the latest Alpenglow model at the 2024 Paris Motor Show, showcasing the innovative “Hy6” twin-turbo V6 engine that runs on hydrogen. This engine, developed from scratch, delivers an impressive 740 bhp, doubling the power of the previous model. The Alpenglow was initially introduced at the 2022 Paris Motor Show as a vision for Alpine’s future in sustainable sports cars. The concept featured a hydrogen-based drive system, which has now been realized in the form of the Hy6 engine.
Unlike the previous Hy4 engine, which was a modified gas engine, the Hy6 is specifically designed for optimal hydrogen combustion. The engine boasts a unique design with a 100° V configuration, a displacement of 3.5 liters, and two turbochargers. The hydrogen is stored in composite tanks and injected into the combustion chamber, where it is mixed with air and water for efficient combustion. The result is a powerful engine that produces a thrilling sound, reaching a redline of 9,000 rpm.
The Alpenglow Hy6 is mounted on a carbon fiber LMP3 racing chassis, further optimizing its performance. The engine delivers a peak torque of 568 lb-ft and a power peak of 740 hp, making it a high-performance machine. The car is capable of reaching speeds exceeding 205 mph, showcasing its potential as a supercar of the future.
In addition to its impressive engine, the Alpenglow features a striking design with aerodynamic enhancements. The rear of the car has been updated with a central fin, side blades, and a raised wing, giving it a more aggressive look. The exhaust system is integrated into the rear light blades, emitting water vapor for a unique visual effect. The front of the car features new airflow channels and sleek headlamp designs, enhancing its overall appearance.
Alpine’s focus on hydrogen combustion technology aligns with its parent company Renault’s commitment to exploring clean-drive solutions. Renault is also investing in battery electric and hydrogen fuel cell technologies as part of its goal to achieve carbon neutrality in Europe by 2040 and globally by 2050. This forward-thinking approach will be on display at the Paris Motor Show, highlighting the future of sustainable mobility in the automotive industry.
