I was driving my car today, and at a light I bumped it down into 1st gear manual mode and hit extreme redline in 1st gear *forgot to shift, as I'm used it shifting for you if you accidentally forget in other auto cars"... Am I in trouble? Is there a fuel cutoff, or rev limiter even up that high to prevent engine damage? I'm WORRIED.

I wish I had my 6spd S6 back.

 

"Extreme redline" = what?
You must have also "accidentally" bumped the max gear number down to 1, too, right? If not, then it won't "extreme redline" when you take off.

 

I was going to comment, but I'll just bite my tongue...

 

There is a rev limiter.

 

i don't understand how this could happen every time i switch it to sports mode it always selects 4th gear as its highest gear to go to.

 

Thank you Buford.

And... I bumped into 1st i meant.. and redlined and stayed there for a split second, and forgot to upshift... so yeah, screwed or not ya think?

 

the IS has so many safety features that i don't think anything serious could have happened to your car. the IS is about as far from a raw sports car as you can go so it's always thinking for the driver. i used sports mode one time, but it wasn't as efficient as putting it in "D" so i don't use it anymore.

 

you will be fine.

 

Thanks again dpIS250, and PNice972

 

Coming from a 6sp you should know that the only real way to over-rev is to go from 6 to 2 or similar misshift. This bypasses the rev limiter and over-revs which can cause lots of problems for your entire drivetrain.

This just isn't possible with a slushbox.

 

Ha Ha slushbox!!! LOL thats a funny term!

 

That's because almost every speed is possible in the A760E's 4th gear:



As you can see, you have to be going over 109 mph for the transmission to not let you into 4th gear. It's almost fail-safe.

Oh, and to the OP - the throttle is electronically limited at 6750 RPM.

Heheee, even with a stick like my long old del Sol VTEC, the red line cuts the engine (8200 RPM). That B16a wound up very fast and needed to stay high for power and I was 24 which pretty much meant I was bouncing off it 50 times a day for the entire 40000 miles I had it. I've bounced off the rev limiter on my IS350. I could probably bounce off it just as much and not have any problems at all.

 

Yup, that's what it's there for. I wouldn't spend all day up over 6k, but hitting occasionally won't hurt anything.

 

Which begs the question, what happens if you flip the shift lever from "Drive" to sport mode when traveling 110 or faster? And no, I don't recommend anyone here be foolish enough to try it.
