Differenece between F1 and INDY

[GTi-VR6_A3]

alright guys please dont flame me but what is the difference between these two cars. i dont get to watch f1 but i do sometimes watch indy. i know they arent the same types of cars so what is different?

Indy is a 2.5L Turbocharged V8 Engine I think, and they use manual transmissions.
F1 is a 3.0L Naturally Aspirated Engine with semi-automatic shifters.

As well, F1 is much bigger in both North American & Worldwide than Indy, thus, the cars are much more advanced.

Indy cars are also bigger and heavier.

i thought that engines varied form car to car

In which?

He explained the difference.....F1 doesn's use a turbo, it is a naturally aspirated V10.
The only variation from car to car in F1 is the engine supplier....
There is also a hige difference in the look of the cars, find some photos of IRL cars and compare them to photos of some of the current F1 cars and you will notice huge differences.....

A few years back I'd have said the difference was that F1 was a series with an open set of regulations designed to promote the best of technical expertise and skill. While CART was a closely regulated, built to a cost championship, with pure entertainment as it's goal.

These days I'm not so sure...

Aren't F! cars basically fully automatic...only time the need to do anything is in the pitstops

:hehehe: :hehehe: :hehehe:

Nope, they have to select the gears, it's not a case of park, D & R there is a full 6 gears to work up and down through.....

[RallyRaider]

At least some of the cars in F1 have seven forward gears plus reverse.

Don't know exactly what the rule is at the moment but I think that fully automatic gearboxes are legal, if they would be of benefit is another matter.

In the past the teams used manual upchanges but often had downchanges programmed in for each corner. It is the on the downchanges that it used to be possible to over-rev or "buzz" the engine. The result of which was a damaged engine.

Would be very surprised if some of the top teams didn't have the whole gearchange sequence mapped out for any given circuit so it could be programmed in for the perfect lap. That type of thing would work well in qualifying, especially given the new single lap format. In the race however there would be a lot of different variables going on that would make it more difficult to programme. The driver would have to have much more input.

You can bet that the lower budget teams would still do all the gearchanges with the paddles. In fact I recall the Forti team, which raced in the mid nineties, only had a CART or motorbike style sequencial gearbox - they couldn’t afford anything else. In fact that car used to bounce around on the track a lot like Indycars do. The better cars of the time like Williams and Benetton appeared to be much smoother, almost on rails in comparison.

and now i know..............the REST of the story.

thanks for explaining it to me wihtout being asses. i knew about f1 having seq man gears but i didnt really know much about indy

Fully automatic gearboxes were around last year in F1, and I believe they still are now. I think they’re going to be banned, and rightly so. Even the low budget teams in F1 have automatic shifts.

As for the differences between the cars, the technical details are endless, but when it comes to how they drive, drivers who have raced in both CART and F1 say that F1 cars are more “delicate” to drive, requiring a lot more precision and therefore being more difficult to drive. Over a (non-oval) circuit, an F1 car is substantially quicker than a CART car, as was proved on the only track both series use, which is the Montreal GP (Circuit Gilles Villeneuve)

Champ cars (Indy Cars) use one of two chassis (Reynard or Lola) with a Ford engine(I think that is all, but there may be more.) These engines make around 750hp@14,000rpm. The cars weigh around 1700lbs with a driver. They use steel brakes and a semi-automatic gearbox with six or seven speeds.

Formula 1 cars are manufactured by many different companies; every competing team must manufacture their own chassis. The constructors are Ferrari, McLaren, Williams, Renault, Jordan, Jaguar, Sauber, Toyota, BAR, and Minardi. Each manufacturer also has their own engine, though these can be purchased from someone else (i.e. Williams-BMW or McLaren-Mercedes). These engines make a variety of powers; the highest figure I've heard is 930hp@19,700rpm from McLaren. These cars weigh about 1300lbs. They use carbon brakes and fully automatic gearboxes (though they will be banned mid-season).

Basically, it can all be summed up from the lap times at the Circuit Gilles Villeneuve in Montreal:

CART Pole - C. DaMatta - 1:19.0
F1 Pole - J. P. Montoya - 1:12.8

hmm....the CART car used to have a 2.6L turbo engine, but now both cart and indy use 3.5L NA engines. just to clear that out. both use semi-automatic trannys. you can see the difference in the body works, and the advantages that the F1 cars have is their weight and their breaks:flash:

I just went to the CART site, they are currently running 2.65 turbocharged engines. IRL is running naturally asperated engines. CART is going to be burning petrol instead of alcohol in acouple years, they want to use something more in line with road cars.

my mistake.....I had thought they went to NA engines....they always talk about the torque, and the torque settings.....they prob. just went to a smaller turbo or something like that
