Yeah but why would you risk on a track instead of using something like a C5 that you can actually PUSH and not care if you crash?

It's like my competition guns getting slammed around into doorframes and in the prone, I don't want to care....I would never use something collectible to compete or train with. I view cars the same way, if I'm tracking then I want to push without fear

 

VWs still use belts.





I love it Did you buy any of them brand new?

 

Has there been any NA C5 Corvette be sub 1:20 at Streets of Willow? Track built S2000s can more than hold their own on more technical tracks.

 

because audis have FWD based AWD systems and notably front heavy weight distribution... have you not heard of "audisteer"?

 

89% rear bias is FWD biased? You are right on the weight, that's why the R8 exists.

No I would have to check around but a bone stock one does 1:24 vs those full effort Hondas. A bone stock C7 gran beats the S2000s handily

 

which one is 89% rear bias? that goes against everything i've ever seen lol

nevertheless most audis (A3, A4, A6, etc...) are classified as FF or AWD layout, but never FR

edit: the most rear bias audi i know of is the RS4 which is 40:60 F/R, but the quattro system is almost exclusively 50:50 in most applications... idk if it's still the case but for awhile i know audis used a haldex system which operated predominantly as a FWD system until the rear wheels slipped

 

Change your driving line. There's thousands of videos of terrible drivers in BMWs on the Nurburgring on sh1tty tires also understeering in a similar fashion. Proper suspension and tire setup and driving lines and you're fine.

 

That 1:24 wasn't bone stock, he's also on upgraded rubber and likely some other upgrades here and there. Nevertheless, 5 seconds is a big difference.

Another well known track driver Kevin Burke in an S2000 sold his track-built C7 Grand Sport to invest more in his boosted S2000 as they were having similar laptimes. At the end of the day, the S2000 chassis is serious and has lots of track potential. That's why 2 decades later and they're still very prominent in the track scene.

 

i'm not saying the cars are necessarily to blame here lol just that the "audisteer" stigma is a thing, and that weight and power distribution play a factor here

you can't "steer with the throttle" on those cars... unlike, for instance, the UR powered IS F boom! back on topic haha

 

Touché, I do wish I had RWD for that specific reason LOL. I can get the rear sliding using heavy trail braking and weight transfer around turns, but not really power sliding unfortunately.. one day 👍

 

I can't tell you what's 89%, but there are a lot more than the RS4 that are 40:60, either using a mechanical Torsen or Audi's own Crown Gear for torque distribution. Like our run-of-the-mill Q7 grocery-getter, which is Type B Torsen. It is 40:60 F:R by default, and can go as high as 15:85 and as low as 30:70. So "almost exclusively" in the bolded statement is a massive overstatement. I want to say the RS4/5 is actually 30:70 by default, but I wouldn't stake my life on it.

What you are describing at the end of your post is the new "Quattro Ultra" system originally introduced in the current Q5. It is very similar to a Haldex system, and has clutches in the rear diff that are disengaged by default, making it FWD until AWD is necessary. Older A3s and such (TT, etc) used true Haldex as they were platform-shared with the Golf/Jetta.

But overall Audi's setup in their larger cars is a weird "tweener" that doesn't fall neatly into either the FWD-based or RWD-based bucket for AWD. From the A4 on up, engines are longitudinally mounted like RWD-based systems and have the rear driveshaft coming directly out of the transmission like RWD-based ones do (rather than a separate diff/transfer case as in many FWD-based cars), which helps dynamics. But that transmission is actually a transaxle, and drives the front wheels directly, rather than via a prop shaft to the front diff. So in that way it resembles FWD-based systems, and the lack of the prop shaft pushes the engine forward a bit. They do wind up a bit more front-heavy as a result--especially V8 models due to the length of the block. That's why you find a lot more V6 options, along with larger engines with shorter blocks like the W8/W12, to keep the weight as far back as possible.

 

Mine and any S/RS car all do, default is 40/60 and under full power it goes 11/89. Haven't had 50:50 since 2006 in nearly anything, we are the 6th version of Quattro these days.

Haldex is only on the cheap cars, A4 and up uses a front/rear layout with a full transfer case system that in later years like my cars have a special center diff that Audi made to get away from this disadvantages of Torson diffs. Out back there are TVDs that can send ALL power to the outside wheel to pivot a car in a turn

Every Audi with few exceptions is a RWD based system except the A3 and TT, the transmissions use a specialized case that integrates the transfer case right on the end to shave off weight and make it as small as possible.



It's a very common misconception Audis are FWD based, they are more accurately described as intended from the ground up as AWD with most of the power going rearward. That's why the torque vectoring diffs are in the back not front etc...

 

You absolutely can throttle steer an Audi with the TVD, the only way I can sustain a drift in a roundabout after all!

They don't oversteer, just powerslide at the limit so you can't treat it the same way as a RWD car, the advantage is you can push so so so much harder on blind runs or in various conditions. Something I love doing is going to random roads and using a passenger on GPS to tell me what the road will do next and just sending it as hard as the tires allow until I start to loose brakes from heat. The AWD cars let you go so much harder

 

Perfect exposition!

I'll only add that there is a driveshaft going to the front diff but all the parts are simply integrated to save weight and space. If desired you can (and people do do this) remove the front driveshaft from the integrated transfer case and diff

The crown gear cars are the ones that max out the bias and can work at all speed/traction unlike Torson that can't send any TQ if one wheel has zero.



Anyhow on the topic of the UR I almost wonder if this happens as a direct result of the valley plate leak allowing hot spots to from at the center of the head(s) and it fails the HG there? I've not personally seen this failure mode occur yet
