Not necessarily full throttle, but a certain amount of acceleration rate. Click on the test details tab and it shows a max acceleration rate of 8.46 mph per second. If the car can’t do that, they just go full throttle.

As far as CVTs and acceleration are concerned, I got a Nissan Sentra rental last year, and it was dreadfully slow off the line. Theory and practice don’t always agree with each other. When it was going faster it was much more eager to rev up, but it didn’t do that off the line. It also didn’t get the kind of mileage I was expecting out of it. A new car with a 1.8 liter engine and fairly tall gearing pretty much matched my 13 year old car with a 3.0 V6 and less tall gearing. Stock vs modded of course, but it didn’t meet expectations.
