Some pretty...interesting designs coming out!
DeltaWing Racing Cars
Nice ideas in here, plenty of safe braking power as the shape lends itself to rear grip when braking. No idea how it will turn, although it will go fast. Good aero shape from having the wheels covered. I think they were talking about running inline-4s with turbos attached - love the idea personally, although it's distinctly un-American. Or V6's with smaller turbos. Whole thing will be regulated by fuel tank size and the amount of fuel going into the engine, rather than by displacement, turbo, or rpm - to try and open up the engine field to many more companies.
Boring to me, they bring nothing new to the table.
Swift (the company who make the gorgeous cars in Formula Nippon) came up with this:
Definitely my favourite, very pretty. Designed so that if car touch the car behind is pushed down into the ground rather than up, where at 300km/h they tend to flip up into the wind and fly away.
I'll be honest, IRL is still very boring, but this could make it a bit more interesting, short of getting some proper racetracks.
Hmm. One of the Dallara cars looks kinda like the IRL Lotus:
