If 10 of my IS300 buddies were to line up and start exactly at the same time and accelerate to 60 or 100mph what are the chances that all ten will reach those speeds at the same time? Some cars could/will be signicantly faster and some slower. I wonder what determines whether a car is a healthy example and is performing to factory specs. In the article below (Comparison involving BMW M3, Audi S4, etc) the M3 didn't perform to the level that other M3's have in the past (for Car & Driver)...........or........... Do you think that maybe when Car & Driver tested the other M3's the weather was cool and dry, whereas this particular M3 was tested in a warmer, more humid climate. Anyways in this particular comparo, the S4 beat the M3 by 4 tenths of a second to 60mph...

i remember when the c&d freaks tested the buick regal grand national back in the '80s. they posted a 4.9 0-60 time bone stock, whereas most other sources were coming in at 5.7-6.0. the reason? c&d tested their unit on a 29 degree day.

there is something to be said about consistent benchmarks. most testers try to shoot for a 55 degree day, as that's considered optimal ambient for combustion engines.

I know that the environment (Temp & Humidity) play a BIG part in engine performance.... What about my example above with 10 Brand New IS300's or CL-s's
starting at the exact same time, They won't have identical acceleration times... right? Some examples will be healthier than others...

Some will be faster, some slower. Since everything is built to tolerances sometimes they can stack up in your favor. For example, SCC's project Celica made as much power to the wheels as a car with a straight pipe. Also, one Supra owner had his dyno 340 RWHP (yeah, not hp, rwhp) when it is only rated at 320 at the crank from the factory.
