^^ Still seems impossible to be that accurate. Police radar is constantly coming under fire for being inaccurate. Imagine trying to get radar precisely accurate, down to 1/10 of a second while rapidly accelerating. Anyway, I was curious to know how magazines get their 0-60 times so I fired off a letter to the editors at C/D. I'll post their response when it arrives. I'm curious too.

Transmission braking at 4K rpm constitutes abuse and would cancel your warranty if Lexus knew.
0 -60 mph time is so irrelevant anyway. Passing time 50 mph - 90 mph counts so much more in the real world.

Car & Driver got back to me pretty quickly.
Here's the entire article.

The VBOX can record speed, distance, lateral and longitudinal acceleration, and position. We use it to record acceleration, braking, and top speed.
The VBOX communicates with the U.S. government's global positioning system, a constellation of 24 satellites that orbit the earth 10,600 miles overhead. At least four of the satellites are above the horizon at all times, and each sends a carrier signal that is picked up by the VBOX's antenna (a small magnetic unit that you affix to a test vehicle's roof). As a vehicle travels, it draws nearer to some satellites and farther from others. As this happens, the frequency of the carrier signal shifts minutely. The VBOX senses this frequency shift, which is also known as the Doppler effect, and calculates the velocity, acceleration, and distance traveled.

yea that was a "mis-post" .. if i brake-torqued to 4k id be sitting still in a cloud of smoke.. i usually dont even get to 1500 rpms..
all you gotta do is hold it for a sec, let off.. and take off!!

^ You don't need to put 4000 rpm to brake-torque launch. Whoever did that wasn't very smart anyway. All you need is 1k~ 1.5k rpm to launch. 4k is your imagination.....
I'm not crazy about 0-60 either, but it is nice to know what your numbers are. There is nothing wrong with that. What I am interested is 0 to quarter mile and upto 125 mph where the IS350 shines. Remember, the 4th gear tops out at 125 mph at 6400 rpm. The 4th gear isn't weak at all for this 6 speed AUTO. ho..ho

ehh well hp isnt the only thing that comes into play.. the is350 is geared much lower then the isf.. and weighs less!
but obviously if you put some 4.08's on the isf it would be insane in the 0-60.. could break into the high 3's pending traction (drag radials needed)

No, it's not conservative at all, when much of the rest of the world is in the low 5's in this car. Just beucase a select few have reached 4.9 and even fewer less than that, doesn't make it conservative. Likewise, just beucase a select few (very few) have hit times like 13.1 on a stock setup, doesn't make the IS350 a low 13 second car.

The stock intake system is already cold air.
Few things I have noticed about the IS350.
1. Full exhaust with gains of around 10whp knock off about a 1/10th
2. Every 30lbs lost knocks a 1/10th off
3. For every 10 degree drop in temperature is worth almost 10whp on the IS350 so you can presume another 1/10th for every 10 degrees.

WHAT?!?!?!
For every 100lbs lost knocks off .1
How is it different for a IS350 than any other car?????????
And 10rwhp for every 10 degree drop? Where did you get this from? I am very curious now. It's like a 1% change in power.
