daverav4, I am happy you decided to come along to answeer some of the technical questions. Fire-away #1. Rumor has it that the gear display never show 1st gear, is it true that we cannot select between 1st and 2nd gear? Fire-away #2. Was the 0-60 7.1 sec achieved w/ E-shift or full auto? If auto, how such faster (if any) do you expect E-shift to be?
Thanks.

If we are asking tech questions:

Do you know the torque converter
stall speed?

Does you know if the speedometer
is electronic or via a cable from the
transmission?

Do you know the dimensions of the moonroof?

Would you expect the car to be faster 0-60
if left in full auto (sport mode) or by manually shifting (with M-mode)
[assuming the driver is very precise at
timing the manual shifts...]

Is the 1-2 shift always handled by
"the computer" even if the transmission
is in manual mode?

Where does this highway go to?

TEG, in brandons pictures it shows that the engine idles at 2200 when the car is started up... Would this be the stall speed your looking for?

No -
If the car idles at 2200, I would guess
one of the following:
1> The A/C was on full blast
2> The car was in some sort of warm-up mode
3> It was a screwy prototype

The torque converter stall speed is how
high of RPMs the thing will let the engine
rev before it starts transferring power
to the rear wheels. Higher engine speed
may allow the engine to get to max torque
band sooner so faster 0-60, but it might
compromise drivability or fuel mileage.
The mileage is pretty poor on the IS300
maybe it has a high stall speed performance
torque converter already. If not, an
aftermarket one might add some performance.

Yep - Bad mileage is often an indicator
of high performance.

Look at the Mileage on a Ferrari F360
or even the Audi S4. Pretty poor.

-----------------------------------------
Still some high performance cars do manage
respectable mileage even with high performance. Sometimes they figure
out the testing regulations and
do tricks that forces the testers do
weird things like start the car in 3rd
gear.
-----------------------------------------
Generally a lighter weight car has an easier
time getting good performance while keeping
good mileage. The new lightweight Toyota
Celica GT-S gets great mileage (23 city / 32 highway )
yet has performance similar to the IS300.

NO, the car does not idle at 2200, i was pressing the gas pedal down a smudge, and thats when i snapped the shot. The idle was at i think 500 as you can see in some of the other picture, i think the e-shift picture shows that.

Maybe daverav4 is a hoax...

It does seem a bit odd that he said
they are giving "him" 3 IS300s.

Oh well, maybe he is getting used
to how to work the bboard.
