How Do 911's accelerate so fast!?

[surferdude00711]

Compare this and tell me how this is:
Aston DB9 911 GT3
150K. 100K.
450HP 275 HP
0-60 IN 4.7 0-60 IN 3.7
Top speed 186 Top speed 190

I got the DuPont registry exotic cars buyers guide. I'm 15 I'm not a buyer but its fun to read about the greatest 65 cars. Including the GTO. Anyhow, how is it that with less HP, worse weight ditribution (Aston is 50/50, 911 is like 47/53 I think), and a lower price, accelerates soo much faster!? The 440k. Carrera GT with 603 hp goes to to 0-60 in the same 3.7! How is it that the 911 always sooo fast in acceleration? Thats the 2004 too. The 2005 base 911 gets to 60 in 4.6, and has 325 HP!? And, its a six cylindar! Thew Aston is a 12! I dont get it... Someone explain or share my frustration and awe lol. BTW that DB9 is beautiful, outside AND inside. Unlike that 911 read end....

I didn't want to bring this up but I will... The 911 base price is 2k. More than an XLR. XLR accelerates to 60 in 6.3. Thats a lot longer than the 911. The 911 is auto or manual too. How would a non GM lover really find reason to get the XLR over the 911? Don't say it has Corvette underpinnings, cause I'm not so sure GM people, makers of the Saturn ION, know more about sports cars than the 911 enginers. Sigma is something to be vert proud of, though; Outhandling the BMW 5.

people buy xlrs for status not speed. thats like saying why not get a corvette over an xlr or a porsche or anything because it is the best bang for the buck no doubt son

[surferdude00711]

Not sure which of those evokes more status... Depends upon what you view in a positive light. XLR does shout I love American style and were the best, which is better than the relatively dorky looking 911.

Gearing, weight, powerband, torque, tires, all have alot to do with acceleration.

"A tank has a couple thousand HP, why can't it out accelerate a 911?"

Think about it.........

Personally, I would take a XLR over a 911 any day of the week.

Edit; just because a car costs $300,000 (Aston Martin Vanquish V12) doesn't mean it's faster than another car that costs $50,000 (Corvette).

[surferdude00711]

weight is very similar 2... all under 3500 i think. jst forgot 2 post that. but out of a 6 cyylinar thats a LOT of hp.

Its probably what you say is a con, It's weight distribution. Its 47/53 has most of the weight in the back when the drive tires are, which in turn inproved traction.

[surferdude00711]

i see. acceleration is a trade of from handling in some ways. whats the corvettes weight distribution?

[giagastormer]

49/51 or 50/50

[doh]

they are not even in the same league together.Porsche is all about 50 years of building race cars not fat luxo liners. Porsche has concentrated on building a car for the enthusiast and not a car for the weekend racer that his wife or her husband goes to work with daily.
It isn't all about horse power and 0-60 times. GM Ford and Chrysler could all play that game if needed. Just look to Nascar and 800 hp carbarated V8s, or ME12 and 550 hp GT's.
I do have to applaud Porsche though for staying true to their vision and not following every little trend, until the Cayan anyways.

911 Carrera Cabrio and XLR go for different buyer groups. The 2 are not direct competitors. One is more sport... other is more luxury.
It's the same reason people will buy an SL65 over a 911 Carrera Turbo S Cabrio. Similar cars... different buyer groups.

I would'nt mind either car, personally, but I would prefer the XLR.
Both cars are going to give you status. A 911 is great... but you're looking at a base 911. Go for a Carrera Turbo S or GT3... a real 911. That's status.

XLR is going to turn people's heads because it's new and not many people have seen it outside a Super Bowl commercial.

XLR competes with SL500, XK8, SC430. That's it.

Exactly. 911s have tremendous traction off the line, but you have to torture the clutch merclessly to get those times.

In 1990, Car and Driver tested a Corvette ZR1 against a 911 Turbo. During the whole test, they felt the ZR1 was definitely quicker, but their instrumented testing showed the 911 was quicker. But they realized that when driving on the street, they would never think of doing the 5000 rpm clutch drops that it takes to get the best times out of the 911, and without that extra advantage of traction off the line, the 911 just didn't feel (and actually wasn't) faster. That's when they came up with their street start 0-60 time, where the clutch is out and the car is idling at 5 mph, then the throttle is nailed from there. It eliminates the magic of the tortured high rpm clutch drops, or the advantage of brake-torquing an automatic, so show how the car will perform for someone who's actually paying to maintain it and drives it accordingly.

so in english, lol, ur have 2 be very fast with ur hands and feet 2 get those acceleration times?

Well, that too. But mainly I was saying that in order to get those really low times, you have to really abuse the clutch, aka, drive it like ya stole it.

The GT3 has more power than 275hp first off. surferdude, go back to the link you displayed and you'll find no where that even Porsche claims their cars have 275hp and do 0-60 in 3.7 I don't know where you found that, but it's wrong.
Still, as said above, Porsche builds sports cars and have all their industry life. They know how to do it just about as well as anyone else out there. They might be slightly slower than Ferrari or Lambo, but they're less money too.
