Just saw this reading the news on CBC app. First race was today. Could help our hobby in a few years for battery capacity and size. A video I saw speaking to Michael Andretti was saying they are doing 170mph and around 25 minutes right now but in say five years it could be up to 200mph light weight batteries that last longer. Competition breeds innovation. All the cars are the same this year, next year they can change things. May be something to keep an eye on. Mind there was a bad accident with Nick Heidfeld on the last lap.
