Does anybody have the times the IS250 does for the 0-40 and 30-70?

I would like to see how it compares to other, like the IS350 on this segment as this is the most used speed range in daily driving.

Stop to 40 and merging on the freeway which is generally in the realm of 30 to70.

Thanks!

Here are the acceleration numbers for the IS350 -



In case the image is broken

0 - 40 = 2.7 seconds
30 - 70 = 4.6 seconds (6.5 - 1.9)

You're in luck, I found acceleration numbers for the IS250 from the exact same source. Enjoy -



Again, in case the picture is broken

IS250:

0 - 40 = 3.9 seconds
30 - 70 = 7.4 seconds (10.0 - 2.6)

And before anybody asks, yes it is valid to arithmetically subtract 0 to 30 from 0 to 70 in order to derive 30 to 70 acceleration.

In 30->70 if you're just cruising at 30, you're probably in 5th gear and your RPM's are < 2k. In 0-70, when you go through 30, you're in 1st or 2nd gear with high RPMs.

It's valid to do straight subtraction but I think you're missing 1/2 -1 second of revving the engine and downshifting.

You are correct. Under "normal" driving circumstances if you are in full automatic mode, you would have to take into account the time required to shift from, say, 6th gear to 1st or 2nd gear.

But, even with automatics, you can (theoretically) force the car to stay in - say - 2nd gear while you're cruising at 30 by using the gear limiters. While the car is limited to 2nd gear, if you accelerate - there will be zero shift delay, and the times above will be valid.

But good point nonetheless.

0-40 in 2 days
30-70 in 3 days

I wish i would have gotten a 350 =/

So weird... I swear it takes me less than 3~4 seconds to go from 30 to 70 when I hit the highway in my 250

Are those 250 values valid for the 250 AWD?

syzygy

No because it weighs around 200 lbs more due to the AWD system. If I recall correctly, most people peg the IS250 AWD's 0 to 60 in the realm of high 7s to low 8s.
