Just wondering if the IS250 has a governor on it. Someone at work said his old is250 (2006, he now has an ES350) cut off at 100mph. I didn't believe this in an IS, so last night on the way home from work (11:45pm, highway was pretty empty) I got on it, and got it up to about 112 before I had to let off because cars were coming up. So is there a top speed limiter? I think I would have reached 120+mph if I didn't let off. I never drive that fast anyways, I was just curious.

That's what I thought. Maybe he had it in 4th gear or something and didn't realize it :rolleyes:

I have a 2010 Is250c never found the governor yet, been over 120mph. I've read it shuts down 145ish....I don't have a good enough stretch that I feel safe enough to try it around KC where I live. I push it at 120!! That's fast for state hwy as is.

Per Lexus:

IS250 RWD: 140mph
IS250 AWD: 130mph
IS350: 142mph

all electronically limited.
That sounds about right to me cuz I pushed mine to write about 127 miles an hour as I let up just before with a 130 marker and I felt like there wasn't much left and I have all wheel drive
