Default Rwd Vs Awd

I was having an argument about the pos and neg of rwd and awd i am an awd kind of guy I like the good traction and I can deal with the under steer. but some people say that u loose a lot of power on an awd system than u do with a rear wheel drive so i was wondering what were ur views on the subject?

You definitely lose more power because of the fact that you have a torque splitting mechanism that sends a certain ammount of power to the front and to the rear (adjustable on some cars) and that is less efficient than a normal drive shaft on an RWD vehicle, also AWD cars are significantly heavier than comparable RWD models.

AWD definitely has the advantage off the line (look up videos of a Bugatti Veyron taking off from 0-300km/h, don't have the link but imagine a RWD trying to put down 1000HP like that lol, all you'd get is a big burnout.

RWD has the advantage if you're racing from say 30 or more miles per hour because the lighter weight is more important than the added traction.

Cornering is arguable, some people feel that lighter weight RWDs have the advantage while others feel that an AWD has an advantage, I think it's mostly up to your preference, AWDs definitely have the upper hand in the wet or snow though, and off road

Personally, I prefer rear wheel drive, look at my avatar, you couldn't have that much fun in an AWD IMO.

ya def more funn rwd (look at my avatar 94 240sx) but for around a track the rwd would have too much oversteer (but then the awd would then get under steer becouse of the fronts spinning) so what do u think of E.T.Cs

Well, all top end racing use RWD cars. They are the best for handling because they don't understeer (granted, they often oversteer, but that's not as bad as understeer).

Also, all the top end drag cars are RWD, but that's only when you get to insane power levels.

AWD simply owns for traction, period. It'll beat any FWD/RWD cars from a dig assuming power levels are similar. Yes, a moderate AWD sports car will handle alot better than a moderate RWD sports car. And driving in non-perfect conditions, like rain/snow/ice, you will love AWD.

Also, weight differences are not extreme, and can certainly be made up for with minor mods. Also, once you really start to modify the car to achieve some nice power, AWD will allow you to keep traction where FWD/RWD will have it's limits.

I'm personally an AWD lover. I've driven my bros old '94 325is and his new '00 SLK320 AMG, and the hole no traction thing gets old. I'm also certainly growing tired of my FWD Eclipse. Boost owns my traction BAD. (From a role I'm good to go though, )

So AWD is nicer IMO. But again, only until you get to top end racing. Then it's all RWD.

Heh, I just randomly saw this video on StreetFire literally 30 seconds after seeing this thread and making that last post.

Basically, in this video, 2WD owns the straights, but 4WD rules corners and corner exits (more grip to get on the gas more and get out of the corner faster)

4WD vs 2WD Races. It's a good watch.

well i would get a rwd front engine car no matter what cuz i luv the oversteer but how come a car like the evo will own the 300zx on a track and the evo i think has 270hp and the 300zx is 300hp (i know the 300zx is heavy but it also has a twin turbo so the spooling up should not be a big problem and it probbably has low end hp over the evo's 4 banger

Actually the twin turbo setup hurts spool time. Twin turbo cars tend to have a lot of high RPM power. This was avoided somewhat by the Supra, which has sequential turbos. A smaller one for low RPM torque, and a bigger one for high RPM power.

An EVO might be able to beat a 300ZX because of the distance put between the cars at launch, and the weight does factor in. I do know however, that the 2.0L 4G63 engine in an EVO has a ton of power up top. I know because I have the same engine and a turbo that is barely smaller than an EVO turbo,

RWD is better for drag racing, but in almost all other departments... AWD is the winner. It corners much better, because you can heavily power through a turn, where as rwd would just spin out.


I love AWD! drag racing doesnt appeal to me much at al, but track racing and autocross!! IM IN!

i once saw this 500hp supra go against a 430hp r32 and the r32 had a stutter box on it so the launch was near perfect it beat the supra by like 1 car length thats were i started thinking that the awd system is better for drag be couse the supra may have had all the power but it was having a hard time getting the power to the road cuz it took off sideways

Thats true... stock for stock yes... But if you look at top fuel, they use rwd with very advanced drag suspensions and have no problems launching... There is no single best system out there for anything... As this topic is pointing out, certain things do better at one thing than another. RWD is truely better thatn AWD at drag racing with a drag setup rear suspension. AWD is truely better at handling.
