Motorsport – and Le Mans in particular – has long been a pioneering proving ground for new technologies. However, as the world zeroes in on net zero goals, reducing carbon emissions in such a high-performance environment for such a long period of time is a major challenge. The race organisers are working with TotalEnergies to explore all the options and Romain Aubry, the company’s Technical Manager – who was born and grew up by the Mulsanne Straight – explains: “There are many different technologies and we are not here to say that one is better than another. “Le Mans is a unique platform for us to test new energy approaches and these include 100% sustainable fuels that were introduced last year; a battery solution we have co-developed with Peugeot and Saft, our affiliates; and a hydrogen refilling solution for MissionH24 project with big plans for the future.” Electric power has been pioneered in Formula E, where TotalEnergies is an EV fluid supplier, and has progressed from … [Read more...] about How Le Mans is using grape residues and hydrogen to drive a sustainable future

Lexus GX Platform Could Underpin New EVs, Will Stick Around For A Long Time
Lexus debuted its new GX SUV this evening, though we've known for some time it will be a rugged, body-on-frame vehicle based on the Toyota Land Cruiser.

What are LMH and LMDh? The top Le Mans 24 Hours series explained
That’s two different rulebooks to which a manufacturer can build a car for the top category of the series. So on the 16-stong Hypercar entry for Le Mans this year there are nine LMHs and six LMDhs. What is LMH and LMDh? LMH stands for Le Mans Hypercar, a rulebook that has been in force in the WEC since 2021. LMDh is new for 2023, but you’ll never see the name written out, it’s not officially an acronym. But it is easy to guess what the letters mean given that the class was formulated by the Automobile Club de l’Ouest at Le Mans and IMSA based at Daytona in the USA. That little ‘h’ on the end refers to the fact that these cars, like their LMH rivals, incorporate hybrid technology. The two types of car are very different in some respects, but actually very similar in others. What’s the difference? LMH allows a manufacturer to design and develop its own car from top to tail - or rather from the nose to the tail. That includes all elements of the hybrid system, which, if … [Read more...] about What are LMH and LMDh? The top Le Mans 24 Hours series explained
