Not positive because I've not tested it yet but.....
With this lineup, I'm an admitted 'nooby' and this may not be relevant to the issue. My car is a new 2021 XC60 T8 so I'm still learning my product knowledge and discovering little things from the manual. Yesterday while waiting for my Lady in the parking lot I was carousing the on-line manual and came across the part describing how to set the maximum speed. That got my attention and I went there. True to form, the maximum you can 'enter' is 112 MPH, but..... It also had a check box to 'seemingly' turn it on or off. I noticed it was checked so I removed it.
I don't know where or when I might get a chance to check and see if it still has a max of 112 and that may or may not have been a way to turn off a 'lower' speed setting or it just quietly opened the gate to whatever you can squeeze out at max throttle. But.... , there are a lot of us on here so I'm confident that if it hasn't already been tried, someone on here will find an opportunity before me. If so, have at it and let us know.
