FYI:

I just sent out this e-mail to Road and Track...
===========================================
I am a long time R&T subscriber, and in the process of buying a new Lexus IS300.

Joe Rusz's recent review left me a little baffled over some details
of the car and your testing procedures. Perhaps you can find the time to help
clarify some of my concerns.

The Lexus IS300 brochure and web site specs (http://www.lexus.com/is/specs.asp)
seem to differ from the R&T report on a number of points:

Lexus says Curb Weight=3270 lb, R&T says 3400 lb (3520 test weight)
Lexus says turning circle=34.1 ft, R&T says turning circle=37.4 ft.
Lexus claims 0-60=7.1, 1/4 mile=15.3, R&T tests showed 0-60=7.5, 1/4 in 15.6

Do you know why your weight measurements and turning circle differ so much
from the Lexus published numbers?

Was your (acceleration) testing done in a standardized manner that should have
produced results similar to the (usually conservative) Lexus factory claims?

(I realize that performance can differ from car to car, and your testing procedures
may not do everything possible to obtain the best possible times).

I also realize that you probably get much mail from people questioning your
numbers, so I do appreciate it if you can find the time to respond to my query.

The difference in R&T's numbers and those of Lexus are more than normal. I'd be interested to hear the magazine's response. Keep us posted. Thanks.

Sometimes the mags are also given a tester car that circulates among magazine editors and is duly thrashed without mercy.

But I would expect a Lexus to stand up to a "good thrashing" and ask for more!

Actually I am guessing that 0-60=7.1 is for the base model (3270lbs) and the fully loaded IS300 with the weight of the electric moonroof, electric seats, LSD, (etc) adds 100+ pounds and reduces the performance, but I want to hear from R&T if this is true. I am still upset about the turning circle numbers circus.
