No, just partly due to it. Unlike many other publications, Road and Track does not adjust their performance numbers to compensate for temperature, altitude or humidity. By way of comparison, Car and Driver's number for the '06 IS350 was 5.1. No difference in the engine between the '06 and '07.

Also, if you look at the drag times link posted earlier in the thread, you'll see that the fastest times posted are '06 cars: http://www.dragtimes.com/Lexus--IS350-Drag-Racing.html

The VDIM is significantly intrusive for performance.

First off, here's all you ever need (and want) to know about the IS350's performance, copied and pasted from another thread -


The 0 to 60 acceleration for the IS350 is about 4.8 to 5.1 seconds, with an average around 4.9 seconds.

zeroto60times IS350 = 4.8 seconds 2007 Lexus IS 350 0-60 mph 4.8 Quarter mile 13.3 (zeroto60times.com)

Torquestats IS350 0 to 60 = 4.9 seconds (torquestats.com)

Road and Track IS350 0 to 60 = 4.9 seconds

Road and Track's IS350 acceleration stats:



Here's the PDF file showing their 0 to 60 run (4.9 seconds) and 1/4 mile run in 13.5 flat, in 90 degree weather no less:

Car and Driver IS350 0 to 60 = 5.1 seconds

http://www.caranddriver.com/features...s_is350_page_8

And, I quote:

"C/D TEST RESULTS:
Zero to 60 mph: 5.1 sec

You won’t be working too hard to repeat our 5.1-second 0-to-60-mph time"

Edmunds IS350 0 to 60 = 5.2 seconds

http://www.insideline.com/bmw/3-seri...us-is-350.html

So there are 5 independent sources all putting the IS350's 0 to 60 in the range of 4.8 seconds to 5.2 seconds, 3 of them being highly decorated/professional (Road and Track, Car and Driver, Edmunds)

Owners have measured a bone stock IS350's 0 to 60 in as low as 4.7 seconds:

It should be noted that that run required brake torquing to some RPM slightly above idle. Thus, the car does not begin to move when you see the RPMs rise or when you begin to hear the sound.

Owners with slight modifications (exhaust, intake) have measured as low as 4.6 seconds or even 4.5 seconds 0 to 60 =

On dragtimes.com, the 5 fastest bone stock 1/4 mile times for an IS350 are as follows:

13.228
13.234
13.345
13.420
13.459



Here's some information regarding the IS350's acceleration with traction control on and traction control off -

As stated above, Edmunds clocked 0 to 60 in 5.2 seconds with traction control off. What did they get when they first tested the IS350 with traction control on? 6.1 seconds. That's nearly a full second slower to 60 - that's a big difference.

I routinely drive around with traction control off unless it's raining. Acceleration from a stop feels much more "free" and "uninhibited" with traction control off.

It should be noted that traction control may very well be engaging even if you do not see the traction control light blink on and off on the dash.

Good luck with your purchase. I'm sure you already looked into this but you should know that while the IS350 is pretty swift bone stock, there is virtually nothing you can do to make it faster (i.e. there's very little aftermarket available for the IS350).

If ability to make your car faster with aftermarket parts matters to you, then don't get the IS350.


Second important point about the IS350's performance - acceleration is strong up to approximately 110 MPH.

After 110 MPH, the IS350 simply falls flat on its face. If acceleration above 110 MPH matters to you, consider getting a different car.

If you're happy with strong acceleration from 0 to 110 MPH (which most people are, I'd presume), then the IS350 will deliver performance in spades within this region, particularly 0 to 40 MPH acceleration.

Very interesting info and analysis. thanks.

Great information CarLx. Thank your for the detailed explanation and the links to support your statements. That certainly gives me some reassurance that I can get a solid 2nd Gen regardless of the year.

As for the performance mods, I really never got into that stuff even with my current STI. I like the Lexus for the reliability, the automatic transmission, and of course the quality of the interior.

Out of curiosity are there any chips or mods that will help the AT to shift faster? I know on my old 330i, Dinan made a software kit that allowed the paddle shifts to be faster and hold longer regardless of RPM. Anything like that for Lexus?? I know I felt a huge difference between the IS-F and the IS350, but those are completely different trans setups and machines. Just curious.

Thanks,
Charles

I am very glad you brought up the paddles because it brings me to the very last nuance about the IS350 that could be a deal breaker to you -

The paddles in the IS350 are not paddle shifters, they are simply gear limiters.

The paddles in the IS-F, however, are paddle shifters.

The paddle "gear limiters" in the IS350 are almost entirely useless, but I've spent a few posts in the following thread to explain exactly what they are and how they can be used -

https://www.clublexus.com/forums/is-...ool-proof.html

In short, for all intents and purposes, the paddles in the IS350 are useless and you do not have the ability to fully control the gear you want to be in (in truth, you have some control - I've explained it all in the thread above).

To answer your question, there is no "chip" you can use to make the paddles "shift" faster because the paddles do not cause the car to shift in the first place in the IS350.

The IS-F, however, does have true paddle shifters.

I've taken it up to 6K rpms a few times but the cabin is so comfy you can't really feel the acceleration.

when you guys say go WOT are you saying floor it?

I'm literally afraid to do that on a city street. If I do that entering a highway, I'm afraid I'll hit the slower cars in the right lanes.

i'm blowing by most cars on the highway as it is, and I've never come close to flooring it. I'm only asking now b/c I read the thread that the occasional WOT is good for slowing carbon buildup

You have to experience WOT, otherwise why get the 350? LOL!

I have a G-Meter that I plan to put to good use once the new BFGs are installed. Hopefully I'll get some 1/8th miles times too.

One thing that is greatly over looked when comparing vehicles, is gearing. The higher final drive in these 350s make them have beastly accel.

I can attest to that in a stock IS350 w/2 guys in the car. SB350 pulls mid to high 4's consistently.

The best time I ever measured with my Gtech was 4.8 seconds and that was with you in the car with me. Go figure...

Since then, I've put light weight 19" Weds on my car, but my times are slower, which is expected with larger wheels. Mostly in the very low 5's. I can still get 4.9 seconds though on a low tank of gas without any effort.



^I think that this device is pretty accurate if it is calibrated properly.

This is why i love my 350 !!

Yep, my friend has a m5 from 0 -70 he could never pull away from me we are always side by side till 70 .. and lets not talk about what happen after 70 mph.. but i am still pretty happy with the outcome.
