So I test drove some cars today while I was in for the air bag pass seat recall on my 07 RIO auto.

2013 KIA Soul 6 sp manual 3 K @ 70 MPH (OK but too big for me, dealer did not have 6 sp RIO)
2010 Toyota Corolla (s?) 5 sp 3K @ 70 MPH (fastest heavy)
2013 Hyundai Elantra 6 sp 1.8 l motor 2.5K @ 70 MPH (a little slower BUT lighter, felt better when stopping)

2012 Hyundai Elantra auto 1.8 l motor 2.3K @ 70 MPH (rented 2011)

WHY can't auto makes make a standard with lower RPMs?
So much for getting a KIA 1.6 with a 6 sp manual.
Bumming.

The Elantra and Corolla was tested because they were there and when again would I be able to?

Can someone confirm the RPMs in a newer RIO at 70 MPH?
Thanks

find that hard to believe, I have a 2012 Soul 2.0L auto and at 110 kmph (68 mph) it turns over 2400 rpm.

RPM @ 100km/h is likely about 2.5-3k.

Small engines need to run faster to have enough power to keep the car going at 100km/h.

Take one of them for a test drive again, then, when you're doing about 50km/h, put it in a gear that you think would have appropriate highway rpm (so, say, 5th gear might be at 1.5k rpm when you're doing 50)... Then floor it.
It won't go anywhere.
Go up to 100km/h, put it in top gear. Then floor it. It'll actually do something.

The harder an engine has to work, the more fuel its going to use.
A 1.6ltr engine at 1,500rpm thats working hard will use way more fuel than the same engine at 3,000rpm thats hardly working at all.

My 2ltr diesel cruises at 2,000rpm in 6th gear at 110km/h. But its turbo'd and is built for low down torque. (1,800rpm-2,500rpm is peak torque)
Whereas, my old 1.4ltr Rio had its peak torque at more like 4,500rpm. Peak power at like 6,000rpm - and 5th gear at 110km/h cruised around 3,000rpm.
