_335-hp-hydrogen-v6-new-alpine-alpenglow-hy4.webp "The French supercar prototype only has a 335-hp inline-four engine, but that will be replaced by a hydrogen-guzzling V6 later this year.<br/><br/>The Alpenglow Hy4 is a fully working hydrogen prototype based on Alpine's 2022 concept.<br/>It will debut at Spa this weekend and will be followed by performance appearances before reappearing at Le Mans in June.<br/>The Rolling lab's 335-hp inline-four will be upgraded to a V6 for a second prototype to appear later this year.<br/>Alpine thinks hydrogen will play a major role in tomorrow's car market, and to prove how serious it is about the fuel, it has transformed its 2022 Alpenglow concept into a fully drivable Alpenglow Hy4 prototype.<br/><br/>The subtly overhauled supercar, which now offers seating for two instead of just one, will make its debut at this weekend's Spa 6 Hours, where it will perform demonstration laps, before doing the same at Le Mans in June.<br/><br/>Contrary to what its hypercar styling and flashy carbon chassis suggest, the Hy4 produces just 335 hp (340 PS) from a 2.0-liter, turbocharged four-cylinder engine, although Alpine says this will be upgraded to a V6.<br/><br/>H2 dihydrogen, together with injected water to reduce NOx emissions, is squirted directly into the combustion chambers under a pressure of 40 bar (580 ps) from three tanks (one on each side and one behind the cockpit) where it is held at 700 bar (10,150 ps).<br/><br/>The inline-four spins up to 7,000 rpm, and Alpine says it gives the Alpenglow performance equivalent to a gasoline-powered car, including a top speed of 270 km/h. Although this engine has been adapted to run on hydrogen from an existing Renault/Alpine internal combustion engine, the future V6 is being designed from the ground up with hydrogen in mind.<br/><br/>Alpine says it's focusing on hydrogen-fueled combustion power rather than hydrogen fuel cell electric technology because its specific power, reduced cooling requirements and similarity in feel and sound to a gasoline-sipping combustion engine make it a good bet for racing applications.<br/><br/>Although it has not said it will directly participate in the Alpenglow race, Alpine says it is paying \")
