Kincsem Hyper-GT: hypercar to use radical hydrogen technology

https://www.autocar.co.uk/car-news/new-cars/kincsem-hyper-gt-hypercar-use-radical-hydrogen-technology "The Hyper-GT chassis will be a carbon tub, understood to be under development by yet another well-known UK tech company whose identity can’t be revealed. McLaren Applied will be responsible for the whole electric powertrain – four electric motors, one per wheel, plus the inverters, traction control systems and a “relatively small” high- performance battery, which should allow the car’s all-up weight to be low against its peers. Total power will be “over 500kW”, or 670bhp" Related: Energy crisis: UK hydrogen breakthrough paves way for 'cheap' truly green power https://www.express.co.uk/news/science/1600898/energy-crisis-uk-hydrogen-breakthrough-paves-way-cheap-truly-green-power Powering the future: Unlocking the role of hydrogen in lithium-ion batteries https://techxplore.com/news/2024-01-powering-future-role-hydrogen-lithium.html
