Bosch and Ligier have announced that the JS2 RH2, a hydrogen ICE-powered concept first unveiled at Le Mans in 2023, has completed more than 5,000km of track running without issue.
The car features a 3.0-liter, twin-turbo V6 engine with an H2 injection system developed by the two companies. Capable of producing 443kW and 650Nm of torque, the engine can propel the JS2 to a theoretical top speed of nearly 300km/h (over 280km/h was regularly achieved in testing).
Dr Johannes-Jörg Rüger, president of Bosch Engineering, said, “The results show that our hydrogen concept could meet the extreme requirements of a long-distance race and provide an excellent development basis for future use in racing cars and high-performance sports cars.”
Currently, the JS2 uses gaseous hydrogen stored in three tanks at a pressure of 700bar. However, the companies state that they have completed the first concept studies of the use of a liquid hydrogen system, which would enable more hydrogen to be carried in a more compact package.
The car will make its track debut at Le Mans in June, alongside the Alpine Alpenglow (which was supposed to run at the Spa Six Hours, however, electrical gremlins meant it was not able to take to the track).
