They only thing that would make it better would be if it was the guys wife driving with grocery’s and the kids in the back.
i LOVE roundabouts!
so how does that work, since they are primarily front wheel drive?
i see the front wheels spinning like crazy, but the rears aren’t. nor are the rears locked up (ebrake)
pretty ballsy, allways dream of doin somethin like that lol
Quattro? :gotme:
that’s what im saying. their quattro system maintains majority of power to the front wheels
Wow…great control. It looked like slow motion.
hottness
not all quattro systems are the same. easy example: the TT has a haldex system but is still called quattro. also in my car it stupid simple to switch out the tq bias to make the car tend to drive the rear wheels, but i am pretty sure thats not the case here, as the center tq bias is accel only (i think).
anyways, i would be willing to bet that is modified quattro. thats my explanation
and its still the front wheels that are pulling the car around , the rear of the car has creater ground speed because the rear end is farther from the centerpoint of the circle the car is doing
the ass end basicly wants to over rotate just like in an uncontroled spin, and the rear tires are getting just enough power to make sure that then dont regain traction
could be uber-shitty rear tires too … plus wet pavement, im betting the car would require alot more speed if it was dry out
i would love to try that in EA… then i would hit a pot- hole and it would be over…
while it is partially true that Audis are essentially FWD cars with and AWD drivetrain, the AWD system in that particular model is the second generation of the Quattro system that uses a torsen limited slip center differential. Audi introduced the design in 1986 and it was promptly copied and cheapened by subaru.
the point i am trying to get at here is that it not primarly FWD. it’s really 50/50
i have done it half way through on many snowy nights. perhaps i now have a new goal
:tup: hahah nice…i wonder what all the other drivers were thinking when they seen him going around the circle in the drift
Good find…
This is actually inaccurate. Subaru introduced its first massed produced AWD vehicle in 1971 the Subaru Leone. Subaru AWD predates Audi AWD by 10 years.
The only reason why quattro recieved so much fame in rallying is because it was an AWD car competing against 2WD competitors.
Besides that, the AWD systems in current Subarus bares little resemblance to that of Audi. Audi was based on torsens differentals. Subaru uses viscous lockers.
Abbriviated VCLD (viscous coupling locking differentials) it is still the prefered diffrential for use in group N rally racing. This is not to be confused with a viscous coupling which is completely diffrent. As a VCLD uses a mechanical differental in conjunction with a viscous slip limiter. Whereas a viscous coupler has no mechanical differental.
The advantage of a VCLD is that it maintains a constant 50:50 split which is always there and requires no action of the viscous coupling to maintain the split. The coupling comes into play in situations where one wheel becomes unladen or one set of wheels is significantly more tractive than the other.
Rarely do we find GrN or ametur rally teams using torsens for the simple fact that a torsens system can be disabled and a car rendered completely immobile simply by unloading 1 of the 4 wheels.
It is a worm gear based system and its “limited slip” action relies on a mathmatical bias ratio. You unload one wheel the unladen wheel produces zero tractive torque and any multiple of zero is zero. Meaning zero torque is able to be delivered to the other 3 wheels.
Audi was able to avoid this shortcoming in its latest gen IV quattro offering by using the brake system to arrest wheelspin.
Now if you unload a wheel the brakes kick in and then you have your brake torque for that individual wheel times the bias ratio and that is what gets delivered to the other 3 tractive wheels.
The disadvantage of this is that if you use it for extended periods of time you are going to cook your brakes. And due to stability problems of individual braking, the system shuts itself off once you pass 45 mph. Leaving you with a center torsens and 2 open axle diffs.
Even Audi’s Latest Haldex Offerings have some major shortcomings. Described Here…

Audi AWD has since been FAR surpassed by the latest generation E-diff AWD systems such as Mistu ACD, Nissan ATESSA, Honda SH, Subaru VCD. All based on similar technology used in championship WRC cars.
^ Interseting info. Good post.
On topic: That’s pretty nutty. Dangerous and dumb, but cool and nutty still.
:tdown: to doing that in traffic
pretty much the best newb post i’ve EVER seen :tup:
good info…haldex is the ultimate suck. i hate it. and i will agree for rally quattro AWD is not so so good. but for a track it is hard to argue against it. speed gt cars would be a good example if they didnt have custom built lsd’s.
after learning more about subaru’s AWD over the years, and then driving one myself in the winter, i think it is a superior foul traction system. VCD just makes more sense than mechanical diffs for low traction situations
