Post Is taking the turns AWD the same as FF?

Is it like in Gran Turismo, where you just keep an flooring the pedal, and keep the steering wheel in the direction of the turn? I'm guessing its probably not like rear wheel drive where you may need to counter steer. Just wondering cuz I've never drive a awd car. thx guys

On our Subarus, we have little sway bars, so there is more understeer than oversteer. So, in a way, it will act like a FWD on dry pavement.

However, on snow, that's another story. The front will pull you to the direction you want, then the back-end will throw the car out to the outside if gas is stepped hard. That's also how I make small-radius donuts to take advantage of these 2 effects. So, in this case, you need to countersteer heavily.

not always, though. There are plenty of times on snow, where it's like FWD. The only differece being, in this car, if you do steer harder, and gas it, it usually corrects that understeer.

but on regular turning, it's much different than FWD. Yes, it'll understeer at first, but once you can break more traction, just point the fronts to where you want to go, and gas it! you'll go there.

toss a 20mm on that bad boy.. even it out..

I did, the car is rather neutral for the most part.. but withm effort you can get it to oversteer or understeer based on input.

hmm, considering the differential and the softness of the stock suspension, the rs tends to act like a fwd car on pavement, however, and this is a big one, if you get brave enough to do this it's super cool and nutso! It works best with 90 degree turns and I wouldn't do it on a racetrack cuz it's probably impractical, but go into the corner with a hard turn, when you hear the front wheels strating to squeal, hit the brake moderately hard for a split second, just enough time to transfer weight off the back of the car, this will swing the rear axel around like a hand brake turn, pop the beoch into 2nd and fly away, it looks super cool and I've perfected it up to 60 mph, but don't flip over! And do 'race style driving' mad responisibly!

As far as turning, in AWD, the tires will squeal later (w/ LSD) FF will squeal once you gun that turn. I'm having too much fun... AWD is like turning on rails. On wet, powerslides are easily controlled.

Some things I can't do with AWD on dry pavement:

Spin the tires from a stop.
Spin the tires going through a turn.
Spin the tires...oh, you get the point.

Cool stuff you can do in the wet w/AWD:

Powerslides.
Gun it from a stop and still not spin the tires.
Throw rooster tails of water, dust, sand, whatever on the car behind you.
Save your a** when that exit on the highway comes up a little faster than you thought.

Cool stuff you can do in the snow:

Just about anything you can't do w/FWD.

Try a big empty parking lot.

Or even at an autocross track.

Myko, if you have a playstation, go rent Colin Mcrae Rally Racing 2.0... You can adjust the power distribution on those cars AWD from front to back to 50/50 and various degrees inbetween. Its a good way to see the differences...

You can also get it for the PC (which is actually better IMO cause you can get better resolutions and maybe custom cars later) and I just saw it in a Add at Fry's for $19! Check it out...

I wonder where be a good place to practice this stuff. Sounds like if I mess up.... I'll be a goner. I'm kinda in this fear stage rightnow, because my last car was rwd, and I my tail went loose on a turn and all hell broke out!! I just gotta keep telling myself.... Mike, don't close your eyes. hehe oops

Yeah, that's about right.

Under power, AWD usually understeers quite a bit less than FWD (assuming the same chassis). Mostly that's because you have double the contact patch to work with. But assuming a smooth turn-in, there is litle or no power-on oversteer associated with AWD cars. They tend to straighten up under the power. Which is why, if something goes wrong and you end up sideways, hit the gas!!!! The car will take care of itself. You just have to try not to hit anything.

And that, my friends, is why I'm probably going to have an AWD car in my garage for the rest of my life.

By the way, many JDM WRX's have planetary center diffs that bias the rear in order to give some RWD-like power on oversteer. Personally I think the whole idea of setting up an Impreza for the dry track is kinda silly, but that's another story.

It's more like FWD than RWD, but there are still a lot of differences. With power going to all four wheels you can really take advantage of tricks from both the FWD and RWD camps.

My quick general answer is that AWD is more forgiving and easier to drive aggressively than FWD or RWD. If there is enough available traction you can recover from most situations just by staying on the gas and using the standard 'steer into the skid' rules. (One thing that can be pretty counter-intuitive to people used to FWD or RWD)

Of course this won't help you if you are just going to damn fast, which doesn't leave you enough room to do that recovery maneuver.

The tricks of the trade are the ones that let you make the most use of the available traction
