RS7 0-60: who knew bigger tires would improve launch times

[limeypride]

The subject is my tongue-in-cheek slur on (prepare yourself for an opinion here) Audi's ridiculous stock wheel/tire setup on RS7s. Regardless of the tune vs. no tune aspect, this car warrants wider rims (even for looks alone) and wider tires to put its power down properly. I'm not a fan of the apparent need to match rear and front tires but it's a compromise worth making.

Anyhoo, back to the subject of the post: the addition of these wheels/tires took almost 0.2 sec from my new and infinitely repeatable 0-60 time which is now @2.68 secs -> https://youtu.be/Y4MhaSBCJCw

2.68 what the eff is in that thing

Very nice !! I don't have an accurate measurement since I don't have a VBox, but watching my dash cam on a clock I came up with 2.5ish on the dash cam vids of my last track day- that was on fastest pass of 10.58 and only diff is I'm using the 104 file. Again, well done!

[limeypride]

Your numbers are simply staggering.

The part that really stands out to me wrt/ the numbers I'm sure you could post and that I did post is this: the cars are mechanically stock (granted, my wheel and tire upgrade is mechanical" but you get what I mean) and we're running only slightly shy of the WORLD's fastest fastest production Hypercars on pump gas --> I mean, WTF!

[cobrario]

Agreed, amazing just a little software and racegas and this car picks up over 10mph in trap speed and about .7 sec in the 1/4 mile, and from your measured 0-60's about .5sec there too, truely a remarkable feat and a remarkable car!

Do you have a tune, too!?!

Sounds like you are really starting to enjoy the car now. Any pics of the new wheel combo? Can't wait for you to give it a go at the track so we can compare the APR Performance times verses the non P car times. Would be interesting to see.

No change really--I always was enjoying the car. The reality is, though, we tend to post slightly more about the things that annoy us than the things we love. For example, I love the electric window buttons--I know, a very small thing but I do love them .

I posted the pics in another thread: http://www.audizine.com/forum/showth...orts-295-25-21

I believe I see in the video the word "Boost" and the boost segments turn from white to red as you brake torque it.

I have not seen that before. Is that something that gets added with the tune or is that a standard feature of the car?

[RSLRS71]

you guys and your slow RS7's. lol

[limeypride]

you guys and your slow RS7's. lol

Ohhhh, you have to back that claim up with some actual numbers or even a cheap YouTube video like I did--throw down, man! .

Let us not forget that my car has "Performance" in its title I'm gonna regret this I fear

It's always been that way on my car. The Performance model has an overboost function that comes stock from the factory--it's this overboost function that gives it the extra torque/HP over the standard Prestige model. As I understand it, the boost gauge changes to red when using overboost. Now precisely what that means to a car that's APR-tuned I don't know.

Thank you. The overboost explanation makes sense.

Insane numbers. What are you using to verify these times? Assuming a VBox for accuracy?

I record a video of the 0-60 on my phone, upload it to YouTube and then time it using the Clock app on my iPhone... I've gotten pretty... OK, I'm teasing. Yes, I use a device called a Solo which is similar to the Vbox. This is the picture I took the day I had APR's stage 1 installed:

I'm trying to wrap my head around the accuracy of this type of timer....I'm not saying your car isn't quick but maybe I'm missing something. If it is accurate then your are at 1.82s with 6 ft left to go to 60ft...a pretty standard timeslip measurement by any account. Now I've hit 1.66s 60 ft times in my lowly stage 1 S6 and I know there are other RS7 guys doing even better.... and I know my car is by no means a sub 2.8s car to 60MPH. I'm willing to believe a stage 1 RS7 performance can do it, but then my car would likely be quicker to 60MPH? Since it has a faster 60 ft time...which I know it is not. Just making conversation as I feel I am missing something....not trying to be an a-hole....
Or is it simply the stage 1 S6 would be faster to around 45-50 mph then the RS7 just pummels it for the last 10-15 mph?

No "a-hole" taken from your comments/questions whatsoever. Your questions are good ones. I wish I could answer them but I've based the performance of this car on this device, my seat-of-the-pants assessment and my albeit-laughable timings of YouTube videos. Perhaps it's time to upgrade to the famed Vbox.

Al that said: even the hacky techniques that I joked about earlier indicate the times I'm getting from the Solo are close or precise but the 60ft numbers you reference don't make sense to me either.

[limeypride]

Here's a run I took this evening using the same device--it was around the time the sun was getting lower and the temps were dropping. Tires were 100+ F @41psi.



As you can no doubt see, it appears the times taken to cover 0-20 and 20-40 were within 0.01 of a second and yet more staggeringly, I achieved that with no additional distance covered... so, yeah--time for an upgrade methinks.

// EDIT: there's definitely something off with this device. That said, though, assuming the speedo in the car isn't wildly off (it's consistently -3mph off above 40mph according to GPS speed app), the acceleration numbers are representative of what the car is achieving. But the distance coverage and 0-20 to 0-40 deltas are whack for sure.

[Ze_Nardo6]

Vbox time!

[limeypride]

Vbox time!

It would appear so.

60' is indicative of gearing and traction moreso than speed- I've been hammered for 60' times at the track only to blow by them at the 1/8th mile carrying sometimes in excess of 15mph more than the car I'm lined up against. That's why when you find 0-60 estimators they use 1/8mile time and speed to estimate 0-60 and not 60' time. Another big factor in the S6 ability to pull very good 0-60/60' when stock or stage 1 is its final drive ratio of 4.09 compared to that of the RS7 which is 3.08- the RS much greater power overcomes that gearing diff but it's still in part why the stock/stage 1 get out so well but run out of steam comparitively after the first gear change. That 4.09 gear is also why Stage 2/3 guys struggle for traction when they're using too much RPM on the launch control. Lots of variables but I know for a fact, and will soon have a Gtech to back it up that my car is pulling 2.55 or so 0-60 on my mid 10 sec 1/4 mile passes. Gtech will be here next week and I'll post videos when i can.

Interesting read, thanks.

What tune/octane is your 2.55 0-60 estimate based on--104 octane I assume?

[cobrario]

Yes sir, Stage 1 104 file using 260+, I hope to use the G-Tech when I run at the track to see how it compares as well. (Correction) For me at least, at $150 less I think it's a better value than the V box and from what I've read it's accuracy is very good.

eventually i will get around to posting some time slips....at CO elevation. met up with some guys this weekend and had some fun with an APR Stage 3+ R8, but that almost wasn't fun with how bad i put the beat on him....i do have vids. ;)

I went with Cobrario and others' suggestion and got a Gtech box--my first thought: what a well built, elegant and compact little device. Anyhoo, my love for its design aside: here's what I recorded on the way back home tonight on my first run:

I love that a four door sedan will beat the new ferrari 812 superfast to 60 and you could buy a second rs7, plus suv to drive in the winter.

While I agree with that 100%, you cannot compare the those two cars, obviously.

you're right Mick, in totality you certainly cannot, but when you edge out an 812 owner or Aventador with a 4500lb "hatchback" in a stoplight to stoplight race, he won't be thinking how much better his car is all around (which it clearly is) he'll just be pissed he got beat by a big ol' boat with 4 doors

very nice! Mine was here waiting for me when I got back stateside, haven't been able to use it yet though as my car is stuck in the garage until Thursday, as in literally stuck because my garage door spring broke they day I left I left 2 weeks ago and the new door won't be installed until tomorrow

I'll agree and disagree to that at the same time. If you're unaware as to what an RS7 is and what it can do, it would certainly be a "WTF moment" and to your point, maybe some bitterness to follow. But for an enthusiast like myself, and most of us here, who knows the purpose of a Ferrari versus the purpose of an RS7, I wouldn't be too bothered. Both cars are an experience, the kind you get from the Ferrari/Lambo certainly cannot and will not be replicated by an RS7..and vice versa

You may be right but I also know there is a lot of ego that often goes with owning a car like that, so I'm sure lots of feathers would get ruffled- or maybe I'm assuming the RS gets less street cred than it actually does, which is entirely possible.

You could not be more right there. Massive egos come with the territory of owning exotics. A lot of guys with big wallets who want a panty-dropper in their stable. Of course that's a generalization as I'm very close to several people who are owners and are as down to earth as it gets, my Father included.

And to your point again, most of those exotic owners have no clue at all what an RS7 even is or what it can do. Which to me, is awesome for us (not including myself in the RS club, but in the club of sleeper 4-doors that can lay a smack down on unsuspecting others).

She bogged a litle at launch so it can do better for sure - and this was my only attempt, afraid of getting caught

The RS7's 0-60 numbers are nuts aren't they. And I think that answers the question as to whether the P-model + APR has any performance advantage over non-P + APR--that would be a "no".

I tried a progressive series of 0-60s on my roadtrip to Vegas and found that altitude, temperature, octane of pump gas and engine temps made a measurable difference--of course, it's easy to say "well, duh" but it's another to actually prove it. Pump gas octane made a big difference (it dropped to 91 the moment I left WA) but altitude and ambient temp were the biggest factors.

What pump gas do you get over there?
