FI and INDY 500 race cars. What is the main difference and which would win if raced together?

On ovals... the Indycars are much faster, as their wide track and turbo-charged cars mean that they can reach 230mph... F1 cars can reach this, but only in the very end of the V10 era (I think it was Pizzonia in 2004 that reached 233mph at Monza)... but their narrow track suspension, grooved tyres and higher downforce would make these speeds harder round an oval... On a road course (which Indycars race on too...)... F1 reigns supreme... in comparison at a venue where both have raced... Montreal.. the Indycar/Champ car was over 5 seconds slower.... thats a lifetime in Formula One... It would be fair to say that Indycar is about 5-7 years behind F1 in technology terms... in some aspects nearly 20 (they've only just fitted semi-automatic paddle shift gearboxes...)

F1 definately.....unless the Indy driver causes a crash :P

F1 will win it beacause it is way faster.

There's been a lot of argument about this. If the Indy cars had EQUAL horsepower, they would be definitely faster. They have lss downforce, fewer wings and drag producing components and are sleeker. As much as I like F1, I would really bet on the Indy car.

On an oval, Indy Car. On a circuit, F1. They are designed for two different purposes. I also noticed that D. Patrick car had a RPM of 10,000 while the F1 cars go upto 19,000 rpms.

indy cars are faster but f1 cars can turn left
