Your RWD vs FWD assumption will fail as long as the maximum engine output doesn't overcome the grip of the tyre under normal weight.

Mine is under the consideration of power loss thru the axles.

It's just science.

A car leans back when its accelerating hard.

If the power is on the front wheels this means less weight is forcing the spinning tyres to the ground. causing wheelspin (no matter how good you tyres are) and a slower take off.

A rear wheel drive car, no matter what, has power going through the wheels with the most weight on them, instantly enhancing grip.

thanks for playing though

Thank you for explaining it more clearly than I did...

how bout power loss? you guys are clearly talking bout traction here right? and the rendering of a slower FWD acceleration is due loss of traction right?

how bout this?

Power loss + rearward inertia causing extra weight at rear wheels, further reducing it's capability of accelerating? although traction was added? which at the first place, the front wheels would've had enough traction to accelerate.

I guess you guys were thinking of really powerful cars where the wheels couldn't hold them, mine is just pure k, say a 1.0 liter engine for a small car.

ahem ... FWD = FRONT Wheel Drive.
"traction" is only mildly "better" in an AWD/4WD and even then needs a VERY clever diff to win when only mildly slippy.
Not only thinking of big cars. FWD will always reduce weight on the front wheels on acceleration and hence reduce traction - even if only 40hp as in the original Mini's which you cvoudl sit on a line going nowhere if you didn't launch properly

(because it doesnt matter what hp you make, if you cant shift, anything will beat you) he then told me that he knew the guy, and he shifts just fine, and he didnt mess up.

is this possible?
Plase spell correctly, use the correct punctuation and use capital letter whenever required.

Please read that sentence you wrote and re-write it if you will, but please try to make sense. Use correct punctuation.

Impossible. After the first dozens of meters are gone, it will be faster. But while traction is stil a issue it will be slower. It can't handle the same amount of revs as the RWD, without wheelspin.

I can vouch for that. I could get Mum's old 1964 Morris 1100 FWD to 'lay a chirpy' on the 2-3 upshift, this car only had 60hp

This convinced me. Thanks Matra, Ferrer, IBR

FWD Cars In My Opinion Are A More Senseible Type Of CAr To Buy If You Not Looking To Thrash A Car Pick A FWD.

There Better In The Bad Weather To Tbh.

But You Wont Get As Much fun In A FWD.

Not Unless You Have A Army Of Horses Under The Hood.

Tbh It Doesnt Bother Me But If I Had The Choice Of The Exact Same Specs In A Car But The Only Diffrence Was One Was FR and one was FF i Would Pick The RWD.


Sorry FWD Fans :P

What's with the capitals? Please don't use capitals on every word.
To what you have said I may add that a good FWD can be more fun than a bad RWD. And it doesn't need too much bhp. everything over 200bhp in a FWD car is a bit too much.

sorry about the caps anyhow i just used the example because i havent been in much contact with FWD drive cars that have a huge amount of HP

i mean the car i drive at the mo is a 3 series bmw compact TDI i love it it's really fast and good off the mark but i can't wheel spin it it has a rev limiter on it,

so it dies out .


but yeah sorry i should have mentioned that the last FWD car that i drove was a mondeo Ghia so that might be why i said you might need a lot of HP.




tbh all depends on what your opinion is i guess
