Question about cars and gears

I recently was talking to someone, and he asked if I saw car auctions on the TV. I told him no, and somehow it came to a talk about a Plymoth Roadrunner. He said it could run at 287 mph, which I know is BS, but didn’t say anything. The fastest production car yet I believe is the Saleen S7, which hits 200 something mph, I believe 220mph. If that car can’t hit 287 mph, no way in hell a Roadrunner, that has a top speed of 135 mph can do it.

Anyways, he did actually bring up a good point, after his stupid one. He said that a car could get a higher speed if you just added more gears. That is true, but he was talking about like bike gears (18 gears). So, why don’t cars make bigger gears to achieve higher speeds. I know they jump from bigger sizes than a bike, but could it do with space? (I’m talking about larger gears, not making 18 gears on a car).

are you talking about production cars?? i always thought the mclaren F1 was the fastest produvtion road car.about the gears…i’m not sure but one thing that must be addressed is the aerodynamics which is more important and also weight issues.

the lotus elise is 1 of the fastest carsacceleration) i have ever driven.its only an 1800cc engine but its secret is the weight ratio.

No, I think it is the Saleen S7, but that is just what I have read. Both are the fastest production cars there is right now though.
