R8 performance

[RXBG]

any speculation on potential R8 weight and 0-60 and 1/4 mile times? i can't believe there hasn't been a thread about this yet!

i suspect a weight of 2800 lbs with the V8/425 hp. with this info i'd say a 0-60 in 4.2 seconds and a 1/4 mile of 12.5 seconds at 115 mph

How does this compare to an M6. I reckon it should be up there.

[RXBG]

in terms of raw numbers it will be close though the R8 will pull away. in terms of handling there will be absolutely no contest.

if/when the M6 CSL comes out that will be different. but by then there'll be a V10 R8 that will make up the difference.

I'll speculate @ 3100lbs, 0-60 in 4.3 and 12.7 1/4 mile time.

I am going to go out on a limb here...

I think we may see a sub-4 second 0-60 time. Say 3.9 seconds. I'd say that the 1/4 mile should be 11.9 seconds....

The R8 is substantially lighter than the RS4, because it has an aluminum chassis and suspension components. It is also a much smaller car, even if it is a 2+2.

One thing is becoming clear. No matter what you do or don't do with the R8, it is a competitor to the Lamborghini's Murcielago and Gallardo. So Audi has to bite the bullet and make sure it doesn't hamstring the R8 for the sake of our friends in Modena.

The R8's job is not only to humiliate BMW but also to make Porsche eat crow. Nothing should deflect these worthy objectives.

Don't take this too serious, but this is from another forum

The R8 is one of the fastest cars I have ever seen at the Ring in person (and I was there to see the Veyron!). Absolutely awesome to have it come along the main straight around 180+mph when in the carpark. The noise was incredible. Whoever was pedalling was VERY competent.

Tailpipe,

A sub 4 seconds 0-60mph, it would be a great headline but to get this figure some other performance figures will have to suffer. It's using the Lamborghini Gallardo chassis so the should be about the same weight, both use a AWD system but one has 500ps not 420ps. If the Lambo can't break the 4 second barrier why will the R8.

One way would be to lower the top speed about 180mph the match for a 997 but well below the Lambo which in turn will help it's sales. I reckon this is what Audi might do.

Handling is where the R8 will really score. I think you are looking at the fastest cross country supercar, it will have a 40/60 split not the 30/70 which the Lambo uses and this is were the biggest difference will appear in the two cars. The Lambo very Italian powerslide and all that and the R8 more controlled and I would say quicker because of it.

[tailpipe]

Leadfoot,

Absolutely right. You expect high-end Italian supercars to have supreme top speeds. The reality is that most people seldom travel at such velocities.

I think R8 will be lmited to 155 mph like all other high performance German cars, although in reality, the limiter probably won't kick in until about 160-165 mph. This will enable better low-end acceleration so the R8 can crack 0-60 in around 3.9 seconds.

I expect R8 to be less heavy than Gallardo, because we have moved on a generation in terms of transmission, suspension in particular, and in the use of aluminium.

[eazy]

Auto Motor und Sport expects that the R8 will not be limited to 155 mph. They think it will go over 186 mph (300 kmh).

Johan,

That guy has no reason to lie, so maybe the R8 might be as good as that man claims, nice find.

Either way, the R8 is be fantastic. I'm not sure if it will be lighter than the Gallardo (I doubt it) but it will handle great and be plenty quick in a straight line. Just don't give it unrealistic expectations yet.

[RXBG]

whatcar magazine very confidently states that R8 will debut only with a V10. maybe the RS4 engine is causing problems and there was a change of plans in ingoldstadt?

[tailpipe]

I am surprised that every one has latched on to theis snippet from "What Car?". They're not exactly close to inside sources at Ingolstadt and rarely provide scoops on anything, so I am inclined to take this report with a pinch of salt.



That said, it makes sense for Audi to put the V-10 in the R8 at some point. In fact, it was always part of the plan. If there is an issue with the RS4's engine, it is likely to me emissions rather than power.



For this reason, I have heard that Audi is working on a turbocharged version of new standard 350 bhp V8 FSI. It should comfortably deliver 450-500 bhp. This may well be an option for the R8 at some point as well as for the A5 coupe.

:MTM:


No turbo option would have fitted in the B7 A4's engine bay, which is one reason why latest RS4 is naturally aspirated. The other reason was they wanted to show BMW that they could do NA.)

[Iceman]

I'm very interested in the TT out there.
What engine/drivetrain layout was in/under the car.
FWD, Quattro, 2.0T (200, 220, 265 hp), 3.2 VR6, 3.6 VR6, magnetic ride, manual or DSG. ???

Dear Friends,

you will know pretty soon about Production Details. Take a look at the 24h Race of LeMans (17th June), you might see a "Surprise Guest".

[Leadfoot]

I take it from that, Audi will entering the R8 in the race, brave move for a new car that has not been seen testing in race trim.

Audi might think that with the Le mans wins under it's belt the R8 roadcar will do the same, here's hoping. A 24 hour race is a long time for a car with not even a year production behind it.

But if there is any company that could pull it off, who better than Audi.

Audi's not entering the R8 in the Le Mans, simply introducing it to the public. Audi's fielding their R10 under Team Joest, should be a great race.

[Leadfoot]

Was just thinking, the weight of a Gallardo is about 1450Kgs and an RS4 is about 1650Kgs. Now if the new R8 is a little bigger than the Gallardo and might be 2+2 but as yet unsure, it is must likely to be heavier somewhere in the range of 1500-1520Kgs.

My point is with the same power as an RS4, it would mean the performance would be only a little better. But this would go against the reports already posted by those who has seen it go. I'am lead to believe that the R8 must have more than the 420ps of the RS4 more like 450-470ps, after all it is going to be the best part of 30K dearer.

One might say, if I'am right where would this leave the V10. I reckon it will produce at least 500ps if not more, Audi can't had BMW having one up on them. This might seem like a small gain on the V8 but it torque will make all the difference. I think it power and torque delivery will be totally different to both the S8 and the S6, a bit like the difference between the S4 and the RS4. It will be a real animal of an engine.

[Leadfoot]

I forgot to add in the last post.

When the new RS5 arrives will possibly use the same technology that has produced the new TT to further improve it weight balance. So with this and the fact that it might be 10-15cm shorter, it will most likely be quite a bit lighter than the current RS4.

I can see only one option for Audi. Give the V8 more power, if this isn't possible don't fit it at all, go for a 3.2/3.6L V6 with twin-turbo. This might be a better match in terms of torque delivery to the V10.

But who am I to tell Audi how to do their job. One has only their opinions.
