Did you guys see the Dec Car and Driver yet. They compare the 911(not the S) to the new vette. The Vette wins by one point, but this takes into account the 20K cost difference. What really suprised me was the performance specs. The 911 0 to 60 was 4.3. Pretty impressive with 325 HP. Wasn't the NA 996 about 5 sec? How do we account for that much of a difference with only 5 HP gain....transmission? Also the S would have made a better show against the vette, no?

 

I believe the 996 0 - 60 was 4.6 seconds. The new 997 is lighter.

I'd spend the extra 20K for a Porsche any day.

 

The 997 is not lighter than the 996.
Car and Driver times are always low, they power shift when they test.
The 996 was tested at 0-60 in 4.8 seconds.
The 997 (base) only gained 5 hp and no torque.
Look at Road and Track's numbers please.

 

If you take in account only the most important test results (Chassis & powertrain) then the 997 will come out on top.
The value result 20 vs. 15, kind of a big difference there, almost too big.

 

Yeah those numbers seem low. The S is quoted from the factory to do 4.6 0-60 and the non S is 4.8.

 

So on 0 to 60 times and maybe quarter mile the 996(02 or newer) should be the 997's equal. That right? To get better times like car and driver you need to drop the clutch from what 3500 rpms?

 

Not only do you need a high RPM launch, but as someone indicated above, they powershift to get those numbers. (They do not let off the gas when disengaging/engaging the clutch.)

 

Supercars.net claims

Porsche 996
Top Speed 280.0 kph / 174.0 mph
0 - 60 mph 4.6 seconds
0 - ¼ mile 13.2 seconds
0 - 100 mph 11.6 seconds

 

car and driver does not power shift their test cars.

 

then why do they always come up with stupidly low numbers like 0-60 in 3.6 on an SL600???

 

they must have better drivers who can launch the cars better. maybe their test strip is really stick?

explain to me now, how do you powershift a SL600?

 

Two cars that both list XXX ft-lbs of torque and YYY hp
can differ greatly in practical power, even if these are
all at the same RPMs. I have a car that produces 330hp
(only) at the wheels, and 430 ft-lbs of torque, but: this motor
produces over 400 ft-lbs of torque *everywhere*. From\
about 1200 rpms all the way to 5000 rpms. Just tapping
the gas, right off idle on cold tires can break them loose
in the wet.
I don't have the torque curves for the 996 and 997, but
if they peak at the same place, the 997 could still be way
quicker if it's torque curve is higher than the 996 below the
peak...

 

I went on this web site and compared the 99 911 to the 02 911. According to the info here the 99 is faster than the 02 despite the increased hp and torque.....Lousy driver in the 02, a ringer of a car in the 99..........what?

 

Must be different test or data. I remember when I had an '02 Carrera, I did see figures that were at 0 - 60 in 4.6.

Don't think the '02 was slower though!

 

The bottom line is 0-60 times are very dependent on the track conditions, the weather, the launch (driver), and the particular car, (clutch, tire condition, tire inflation, etc. And some cars of the same model are just stronger than others in the same line engine wise).
