1) We congratulate Team NasaMax for their 17th place at the 24h of Le Mans. Indeed, this team uses a car that consumes exclusively biofuel: (bio) Ethanol. Other technological tricks are present on the cars (like any racing car). Hoping that this initiative does not remain an orphan.
See the full ranking on the official website of the 24h du Mans
2) Online posting of a page entitled "Diesel and Water" from the site of the Ministry of the Economy, Finance and Industry concerning the addition of water in an internal combustion engine of Diesel type (research on aquazole by ELF and ANTAR).
Many explanations seem to be common with the water doping carried out on our Zx which, however, gives better results in terms of fuel economy.
