Don't think Ford will ever get back in until Edsel Ford II kicks the bucket. Any German manufacturers, probably not likely if they're really planning on banning ICE by 2030.
Brakes are definitely going to have to be worked on. That whole package in 2021 is probably going to be brand new - engine, aero, chassis, etc. They're already pushing the limit on brakes from what I've heard from people like Mike Hull.I find it hard to believe that they would want that. They can't keep the cars down on the track now and haven't for years. It's like Penske said 20 years ago, those cars will only go so fast around Indy and they just about hit their limit back then.
They might want more horsepower for the straightaways to pass, but they better have some big brakes for the corners.
Remember Mario going airborne? Castroneves? Remember Mike Conway/Ryan Hunter Reay? I'd say 230 is about the limit. Maybe a little more.
They better get some extra paint for that wall on Turn #1.
Biggest difference at street circuits, IMO. Will Power said with the DP01 they'd be wheelspinning from the exit of the fountain complex at Long Beach all the way down to turn 4. Those street circuits already have so much less grip than typical road courses, and slower, tighter corners. They're gonna be a bitch to drive on. Ovals are gonna require a lot more lifting/braking input too, I think.
