Alpine presents Alpenglow Hy6 with the brand’s first 6-cylinder hydrogen engine
First presented in 2022 as a concept car, Alpenglow returns to the Paris Motor Show in 2024 in its most advanced version, the Alpenglow Hy6.
Alpenglow Hy6 is the latest version of Alpine’s hydrogen-powered rolling-prototype, which was demonstrated at the 2024 24 Hours of Le Mans in its 4-cylinder configuration with Alpine Ambassador Zinédine Zidane on board.
A world first and the centrepiece of this evolution of the Alpenglow concept, its all-new V6 engine developed by Alpine is specifically designed to run on hydrogen. Its name, Hy6, combines the notion of hydrogen and the number ‘six’ for 6 cylinders.
Particularly high-performant, this hydrogen-fuelled, twin-turbocharged V6 boosts the vehicle’s power output from 340 to 740 bhp compared with the first road-going Alpenglow Hy4. In addition to its exceptional performance, the sound is enriched by the characteristic musicality of a 6-cylinder engine, offering even greater pleasure to lovers of fine pieces of machinery.
Alpine’s hydrogen-powered internal combustion engine technology combines environmental innovation with sportiness to offer a new way of reducing sports cars’ carbon footprint. It’s also an exciting avenue for motorsport, with technological mastery that makes Alpine a trailblazer.
The hydrogen-powered Alpine Alpenglow Hy6 has refined its design to present its new engine in a transparent case and adapt its aerodynamic characteristics to the new performance of this rolling laboratory.
Revealed in 2022 as a concept car designed as a blueprint for the brand’s future direction in design and sustainable innovation, Alpenglow already showcased the high-performance potential of the hydrogen combustion engine, a realistic solution for offering sports models with high carbon reduction targets. In this way, Alpine is ready for possible changes in future regulations. It is also a symbolic application of the name Alpenglow, which takes on its whole meaning: an optical phenomenon that lets a glowing light shine on the mountains before sunrise, in other words, an evocation of the dawn of a new world.
Following on from the first road-going prototype powered by a 340 bhp, turbocharged 2.0-litre 4-cylinder engine, this is the Alpenglow Hy6 equipped with an all-new engine that offers more than double the power. It is a ground-breaking 3.5-litre V6, developed entirely by Alpine for optimum hydrogen combustion. It produces 544 kW (740 bhp), or more than 150 kW/l (210 bhp/l), giving Alpenglow first-rate performance, ideally in line with the spectacular design of this rolling laboratory, which is evolving with the arrival of this new motorisation.
Bruno Famin, VP Alpine Motorsports, said:
With the development of this brand new Hy6 V6 engine, we are demonstrating our commitment to hydrogen research, which could herald motorsport applications with high-performance levels.
“A solution for continuing to cultivate the passion for motor racing using a very noble V6 with remarkable specific power and a sound to thrill drivers and spectators with its maximum revs at 9,000 rpm. The Alpenglow Hy6 concept is the perfect example of what is possible to achieve the essential step of reducing carbon emissions in motorsport.”
