Sad to say that website is published wrong info.

The GTP is a special and unique car in many ways. First application of a the Chevy small block in a FWD car and the first car to have wider front tires than the rear.

the tire sizes are 255/45 r18 and 225/50 r18.these tires are w speed rated.they have wider front wheels help it in the characteristics of a fwd cars
and also many sites have their own info.some say fwd some say rwd.

edit: post 300.

From the same website:

Quote:

Wider front wheels help the GXP achieve a more neutral cornering stance and optimize the inherent handling characteristics of a front-wheel drive vehicle.

The content editor typed in R instead of F. It's always been FF. I thought Pawan said it was FWD, and whatcanthisbe said it was RWD. My apologies.

just checked up some more sites and some say rwd and some fwd but in pontiac's site they say fwd so the info was wrong.

good question, ive driven quite a handful of RWD(bmw 330i, lexus IS 300) cars in heavy snow and with the traction control off, ive been passed by honda civics and minivans especially uphill while i was still fighting to get the car to go straight!!!!
but with traction control on and a good set of snow tires (NOT all seasons) RWD is perfectly driveable in tricky weather, just have to remember to give it opposite lock if you loose the rear end

edit: the grand prix is a common rental car and i can assure you it is FWD and yes it understeers.
:)

people was FWD introduced first or the RWD or AWD?
as far i know Lamborgini i guess introduced the rearengined RWD haveing the engine placed in a horizontal manner like the one in the present FWD cars like accent, maruthi etc say what?

Old thread which i found while searching the site for something else.
Another factor is weight-distribution.
The traction available at the driven wheels is the product of the load on it and the coefficient of friction. Thats why vehicles used for carrying higher load, like Qualis and all and the higher load carrying vehicles are RWD.

In fact by the same theory, AWD's should also accelerate faster(but i mean in a condition where there is loads of power and hence wheelslip), because affectively you have higher traction force available, which is the whole weight of the car multiplied by the coefficient of friction. Considering a case where I have a RWD or FWD, accelerate hard and there is lot of wheel-slip. If the same car is equipped with AWD, it would be able to put power to the road instead of it getting wasted in wheel spin. In FWD and RWD, traction would be lesser as it is limited to the load only on the driven wheels.

Thats true. The Veyron isn't as quick as it is just bcoz it has 1000ps/1001nm. It finally comes down to how much of that power can be converted into performance through traction.

The power to weight ratio of the Veyron is some 530bhp/ton compared to the 550-560bhp/ton of the Mclaren F1 and yet the Mclaren is slower to 100kmph by 0.7 secs. Had the Veyron been a RWD, things would have been diff.

my ride is a 92 model with No Traction control, No ABS, no modern control techs, around 200bhp at rear and its a sexy ride,
With a rwd i feel Strut braces should be oem as this helps alot in cornering and the drift is controllable obviously if you know what you are doing and dont drive in panic rwd is fun to drive in any condition.

Why rear-wheel drive is coming back. - By Mickey Kaus - Slate Magazine

your nissan is beautiful man..:Shockked:

now getting back to the point...The only reason we dont get RWD is because the mechanical efficiency is lower than FWD cars and thus the Fuel efficiency is reduced. Mechanical efficiency is low because of the drive shaft and rear differential

The main reason for not getting RWD is not about mechanical efficiency, but the cost that is incurred with a RWD.

For a FWD the drivetrain components can be replicated across various models of varying dimensions which the RWD architecture won't allow. This reusability factor makes platform sharing easier. So it has to do more with manufacturers bottomlines rather than the consumers interests (off efficiance, safety or handling).
