Whoah, that's a lot more changes than I thought we were going to see. - Wings are different, with active aero. Wings open every lap, on every car. - Cars are shorter, narrower, lighter, with slightly narrower tires. - Ground effect floors are gone. - Boost button - max power at the push of a button (battery charge depending) - Overtake - attacking (replacing DRS) - Recharge quicker - All new power unit. 1.6L V6 turbo, but engine loses power, but battery gains power...a 50/50 power split - MGUK - gone - Sustainable fuel - Cars are built with more driver safety built in... - Drivers will have the same power, but less grip.
