Run against a Audi A8

Paul, I sincerely hope you're registered for this year's NSXPO (www.nsxpo.com)....
This way, you can stay within the "Family" and not worry about those Audi folks ;)

Seriously though, there are many variables going into your run-in with the A8 (ie: rev's at time of acceleration, shift point etc.). Personally, the A8 is a nice looking car, but I've yet to run against one yet.

See you in a few weeks at the NSXPO at Sears Point (oops....Infineon). :D
 
The A8 should be no much for the NSX.. 300 HP 4000+ pounds.. you must not have been doing something right..
 
Can't remember if it was an S8 as I know that is a screaming car! All I know is I mashed it and shifted at 7500 and he had pulled from me. We went around a long turning fishhook to get on the freeway and he was gone. I held him through the turn and we both got on it getting on the freeway. I ran it up to around 110 and backed off as I had my wife in the car.

I hope it was an S8 as I thought I could take him in the NSX.

I just got the car so I am still trying to understand the performance.

For maximum acceleration, shift it right around redline, 7800-8000 RPM.

It didn't happen to say RS6 on the back, did it? ;)
 
lb/hp for the Audi A8 and S8

2004 A8; 4400lb/300 hp = 13.3 lb/hp
2003 S8: 4068lb/360 hp = 11.3 lb/hp

NSX, 3020 lb/ 270 hp = 11.2 lb/hp
NSX, 3160 lb/290 hp = 10.9 lb/hp

If the car that pulled away from you was an A8, you are doing something wrong in your driving because even with both you and your wife in the car, the NSX has a far better wt/power ratio (unless you are both VERY well fed ;) )

If the car was an S8, and you have a 290 hp NSX, you still have a better weight to power ratio and in fact even with the 270 hp NSX, your weight to power ratio is the same as the S8.

In the right hands the NSX will beat the S or the A8.
 
even my cousin who used to his 320+ hp S4 thinks my 91' NSX had better accelaration, I just don't see why the S8 can take off from you... Would it probably you didn't go fast enough at the corners (out of your powerband when exiting the corner while the S8 was gunning it at its powerband??)

but well said, shiftright2, girlfriend/wife/mom or any kind of those female passenger could slow down the car big time... My girlfriend basically warned me if I ever "tried" to bring the tail end around, she will "never" sit in my car again... ummm...

My mom is also a G-force alarm, whenever the G-force exceed .1G, you will hear her starting buzzing/ screaming......
 
Well now you guys have me thinking my car isn't pulling hard enough. I put it to the floor and did not take him. The car seem to run perfectly, though and it only has 9000 miles on it. All stock!
 
no one has yet mentioned the a8 possibly being modded...

Kids around here love modding A4s, so why not an A8? ya, its more $$ but they could probably afford it.

S4's are no match for NSXs...at least in my experiences...

I've run 3 or 4 S4's and it hasn't even been close. (2 highway runs and two from a dig).

Then again, i just found out last night my car is 300lbs lighter than stock! :D

No it isn't. According to your report, your car was within 200 pounds of stock (remember, changes due to the amount of gasoline in it don't count), and if you're driving around with things that you removed at the drag strip, like the passenger seat for example, then even those weight savings are not applicable...
 
dont underestimate the power of A8, they are pretty fast.

i dont know about modded A8, how many ppl that you know would mod an A8 or do ppl even make mod stuff for A8?

i raced an A8 when i was back in n. cal, after i miss-shifted, i couldnt not catch him anymore. That was with my almost stock supra tt.

Maybe the same car that is hunting for jap sports cars? ;)

you can talk all the number you wish, but line them up in real life and you will see

btw, weight of a car dont play as much of a factor @ high speed

Audi A-cars and NSXs

I read this thread with interest...

I have a '91 with 125k on it. Back in June I had the t-belt and other goodies changed, as part of what should have been done by the previous owner at 90k. I have one of Mark Johnson's SS dual canister exhausts and adjustible Koni's; other than that the car is completely stock.

I have to agree with who said there's a lot more to it than than just power weight ratios, or raw HP. It's gearing, engine condition, drag coefficient, wheel size and how big the driver's cojones are.

I've lived in Germany for the past two years with this car (and almost 17 in Italy back in the 80's and 90's), so driving at speed isn't new.

Anyone underestimating recent Audis would make a mistake. Even the big wagons scream. I've cruised at 90-110 and had those things blow by me. They are very fast. No, I've never raced one, but I've seen enough Audis at speed to know that they do in fact go pretty damn fast. But, not to worry, ours are pretty damn fast too. Mine, old and a bit dented, has seen 165mph, and it doesn't take too long to get there.

A friend, before he shipped his BMW M3 home, was TRYING to lose a VW Touareg, their new SUV, and didn't even begin to pull away from it until he hit 160mph.

The Germans build fast cars, and Audi is one of them.
:D

You should be gaining on him if not passing him through the turn :o

Either way, I'm sure you're enjoying every second of your bondage with the NSX. Give it a few weeks, by then, you'll eat S8s for breakfast, lunch and dinner. Even when my car was stock, modded M5s (not counting the supercharged ones) couldn't pull from me. I go to M5 meets all the time.

P.S. It is a proven fact that your car lose performance when you've your significant other in it.
 
im kinda sad after hear this news. anyways. im sure when the audi driver got home he wishes that he has an NSX on his driveway.

power ain't everything.
 
I know the Audi is a fast car, but I can't possibly see how an unmoded A8 or S8 could take even an early model NSX. Looking at Edmunds the A8 weighs 4399 pounds and 0 to 60 in 6.3 and the S* weighs 4068 pounds and 0 to 60 in 6.2 seconds. This is significantly higher than even a stock 91. You would have to have some pretty expensive mods to drop a full second off a 4000+ plus pound vehicle.

It leads me to believe that either something is wrong with your car, or you didn't drive it to its potential. If not, then you came across one of the fastest A8's around.

I have a 2000 Audi S4 and a ’92 NSX and have driven them both several times over the years on the same track. Here are my observations: In the dry, the NSX will kill the S4, no contest. The difference in turn-in speed between the vehicles is dramatic with the NSX being able to hit the corners much faster. The cars handle differently and the Audi tends to shine after you’ve made the corner and then mash the throttle and since it’s 4wd, you can steer by the throttle—but you’ve got to slow the S4 down a whole lot before it can make the corner. In the wet, the S4 kills everything. :)

Paul and I did an impromptu run through first and second gear over the weekend, and his car is actually a little quicker than mine! I haven't dyno'd or raced my car yet, but I don't think my engine is lacking in power. But my clutch nearing the end of it's usable life is a different story... :)

My suspicion is that Paul met up with a modified Audi. A friend at my office has an Audi (not the one Paul might have seen), and he is aware of people putting NOS, etc on their Audi's. From Paul's description of how that Audi pulled away on the freeway, that is the only explanation IMO.

Why is that?

Well son,

There are things in life that simply can not be explained..

eg. Barmuda Triangle, UFO, great pyramids, and why girls either dumb as a tree or just butt ugly..

ok.. enough of those none sense, i have nothing to back it up.. I just read it from Supra post before.. something about at high speed, aerodynamic plays in a bigger factor.. and weight become lesser factor.

that's very true... For air at standard conditions, V in mph, and drag in pounds of force, the equation for drag is:


Drag = 1/391 x Cd x A x Vsquared

This equation shows that to calculate drag you need to know three things: Cd, the drag coefficient; A, the frontal area of whatever you’re driving through the air; and the speed of air past it. This equation shows an important point—aerodynamic forces are proportional to the square of the speed. That means you quadruple the drag or lift when you double the speed.

The drag coefficient, Cd, is important because, in concert with frontal area, it determines the power cost of pushing a shape through air at a certain speed. A small, low-Cd road car will have a higher top speed than a larger, boxier car with the same engine power.

Bottom line, eventhough the NSX is much more aerodynamical than the boxy A8, the NSX has trouble to blow the A8's doors off, because the A8 has twice the number of doors...
:D

Judging by how quickly the Audi pulled away from the NSX you
would have to suspect that it was an RS 6. Those things just scream.

450 hp, twin-turbo... I know, my boss owns one !
