I tested my 0-60 recently and was very impressed by the numbers so I thought id share and hear from anyone else who ran their 0-60 to see what numbers people are getting.

Car info:
254k miles
2008 LS 460
Both runs, no brake boost straight flooring it
CEL for p0420

Unfortunately the speedo is not an accurate way to test performance. The way the sensors work, it is fast 5-10mph, so in reality you're hitting 50-55mph.

There aren't even modified LS460 running sub 5s, thats stock GSF or modded/tuned GS460 times.

You should get a Dragy, it will tell you exactly what you run, and give you a lot more data, 0-100, quarter mile, 60-130, and you can see what other Lexus are running around the world.

 

Yeah, speedos aren’t 100% accurate, but they’re definitely not off by 5–10 mph, at least on modern cars. Most are within about 2–4%, which is typically only 1–3 mph at highway speeds. From what I’ve seen, LS460 and IS350 speedos fall in that range, so the run would still be just about sub-5. That said, I agree that a Dragy is the best way to verify it, and I’ll run one when I get the chance.

 

Even on newer Lexus, it's off by a bit. Here's a much newer RCF(same sensors) showing a 7mph difference at "66" and 10mph difference at "100". Obviously there would be some lag, since its a bluetooth device, but 5-10 is a pretty good estimate.

I look forward to your times though, it's always nice seeing fast 460s

 

Use as a scan tool and log the vehicle speed in live data, I use transmission output shaft speed and gear with measured tire size to calculate real 0-60 and I have never seen better than 5.4 from a dead stop.

I also just use a draggy when I'm lazy

The LS460 dash speedo is also VERY inaccurate even with "correct" tire size, like 5-7mph optimistic if not worse.

 

I tried logging this with my scanner and noticed two important factors. At steady cruise, the scanner and speedometer were about 2–3 mph apart (for example, 61 mph on the dash vs. ~58 mph on the scanner), which lines up with normal factory calibration. During acceleration testing, the scanner’s vehicle speed PID updated much more slowly than the speedometer, making it difficult to use for accurate 0–60 measurements. On video, the scanner was still showing around 44 mph as the speedometer approached 60, then continued updating toward ~58 once speed stabilized. Because of that lag, I didn’t consider the data reliable and discontinued the test.

 

Well no offense but I have a "slightly" better scanner so my data stream is way faster lol!

Most should just use a draggy as a $5800 scan tool is a bit expensive if you aren't using it for other things.

 

Well “use a scan tool” is misleading when it only works properly with a $5k+ professional unit. Most people don’t have that. If that had been clear, I would’ve just used Techstream.

 

I do not have the credentials or mechanical background to offer much, let alone relatively new to the brand, but can and will back 'like 5-7mph optimistic if not worse'. 100 percent. I live in a very heavily 'scanners accompanying speed limit signs' area.

 

Mine was 93mph at 100 indicated so....

 

I've verified the accuracy of the speedometer by a gps app on my phone. The speedometer in my LS is dead on accurate at 79mph. However, in my wife's '12 Highlander and daughter's '12 RAV4 at 79mph both speedometers show 81-82 mph. So does this mean the mileage is actually lower than indicated?

 

Yes, it varies car to car so you need to check your actual vehicle. I normally check at 100 mph for increased accuracy

 

This was absolutely not the case on either of the LS460s I had. They were all off by 2-3MPH at highway speeds, definitely not 5-7. Every Toyota/Lexus product I have owned is off by about 3 MPH. So at 75 on the speedo you're going 72-73.

 

Go 100, it's off 5-7

 

Its not off 5-7 at 80-85...I don't drive 100MPH so whatever it is at 100 doesn't impact me...it also wouldn't impact a 0-60 run...
