All speeds in 6th gear.
The numbers don't seem right even if we consider the external factors such as incline, wind direction.

In the Innova, 100 to 120 increases the revs by 250 RPM but 120 to 140 increases the revs by 200 RPM? The gear ratio doesn't change.

Similarly for the Verna CRDi, 100 to 110 increases the revs by 250 RPM and then 110 to 140 by 500 RPM? If the revs go up by 250 for every 10kph increase in speed, then 110 to 140 should see the revs move from 2000 RPM to 2750 RPM.

Does 1800RPM @ 100KPH make it right?
Gear ratio won't change for sure, but viscous coupling till its locked, give or take a few RPMs based on road and wind conditions.

Toyota Yaris Petrol CVT, all figures tested with cruise control and torque pro app.

60kmph - 1000 rpm
80kmph - 1320 rpm
100kmph - 1690 rpm
120kmph - 2030 rpm

This is the first time I've taken the car to 120kph after spending 1 year with it. I must say I am very impressed by the way it masks both the speed and the noise. You'll only feel the speed if there are other vehicles around or by looking at the speedometer. Other than that, I could hardly feel the numerous potholes and suspension joints even at 120!
