Alpine shares Toyota’s belief that hydrogen could be the key to preserving the combustion engine. While the Japanese automaker has been exploring hydrogen technology in its three-cylinder GR Yaris and GR Corolla hot hatches, Renault’s performance division is showcasing a concept that features a larger four-cylinder engine. Now, they have revealed a supercar concept that boasts an even more powerful V-6.
The newly uncovered Alpenglow Hy6 builds upon the Alpenglow Hy4 concept introduced a few months prior. The earlier model served as a running prototype of the static 2022 Alpenglow, but it has now been replaced by a robust 3.5-liter V-6 engine with twin turbos, departing from the previous turbocharged 2.0-liter engine that produced 340 horsepower. This new powertrain generates an impressive 730 hp and 568 lb-ft (770 Nm) of torque, all directed to the rear wheels.
According to Alpine’s performance division, the new six-cylinder engine has been specifically engineered to operate on hydrogen and is paired with a sequential transmission.
Capable of revving up to 9,000 rpm, this V-6 relies on hydrogen stored in three separate tanks: two are positioned within the side pods, while the third is located behind the cockpit. For safety reasons, all tanks are situated in ventilated compartments, ensuring no connection to the cabin.
After two years of development, the Alpenglow Hy6 features an innovative V-6 with an aluminum block and dry sump design, achieving a remarkable output of 211 hp per liter.
This mid-mounted engine is integrated into an LMP3 carbon chassis, allowing the supercar to exceed speeds of 205 mph (330 km/h) while producing zero emissions. The design includes an Inconel exhaust system that releases water vapor, cleverly incorporated into the taillights.
While Alpine has confirmed its intention to produce a supercar, it remains uncertain whether it will be powered by a hydrogen-fueled combustion engine or a fully electric drivetrain. Meanwhile, the French automaker is preparing to make its U.S. debut in the next couple of years.
At the 2024 Paris Motor Show, Alpine is showcasing the Alpenglow Hy6 alongside the A290 electric hot hatch, which serves as a performance variant of the new Renault 5.
Additionally, the A390 concept is on display in anticipation of its production model, set to become the company’s first SUV next year. The limited-edition A110 R Ultime is also featured this week in Paris, marking the brand’s most expensive vehicle to date.
