Driver experience is the culprit.

Test drivers need to spend more than an hour or so in the car to master the F. There are guys running 4.2 in stock and new Fs.

 

^^^^^^^^ 100% agree.

4.6 sec is a reasonable number given by Lexus, as many high performance carmakers list numbers reachable by average Joe if they list 0-60 times at all.

If you look up Porsche 911s factory 0-60 times, very conservative.

 

wow! 4.2 is pretty impressive

 

Time to get a new car.

 

I agree. It's obvious Lexus' claimed 4.6 second acceleration number is a "stomp and go" number with traction control engaged, sport mode enabled, and automatic up-shifts. You'll notice that higher end performance cars that do 0-60 in under 4 seconds all have a launch control procedure to get that number. In most cases, that launch control procedure can't be setup quickly enough or timed right for a stoplight race so it's a bogus number in the real world.

 

??? Did I miss something

 

my 2011 was faster than my 2008, but so many other things to consider its a day to day toss up, track conditions , weather, tires, da, just a few things that will affect 0-60 and 1/4 mile times

 

. Yep...it's called marketing.

 

I've been driving the ISF for over 5 years, 3.8yr on a 2008 and 1.5yr on a 2012. I always go to the same track thoughout the year, so same track, same driver, same way of driving. My 2012 is slower than my 2008 from a dig, all the time. From a roll they're the same, through corners the 2012 feels better.

 

Interesting. Thanks for your comments.

 

Is there a weight difference in the favour of the older models? Maybe that explains off the line peppiness of the older models.

Driver and environment. The car has no problem hitting the lower 4s.

 

Looks like 4.4 if not better to me.....

 

is the same case for is350

 

This site, which lists 0-60 times, places the 2011 IS-F at 4.2 sec.

Autorooster places it at 4.5 sec

MotorTrend claims 4.3 sec for the 2011 model

One big difference in 0-60 times for the F is, what mode did you use? Both standard and sport mode work to minimize wheelspin, so the fastest 0-60 times would come from disabling the stability systems and relying on a talented right foot.
On a personal note, I've never yet had a car get past me in a 1v1 on the highway.
