I didn't try 0-60 pedal-to-the-floor pulls as that's not really how I drive my cars. My butt says the MYLR is easily quicker most of the time, especially on the highway / at higher speeds. Wife felt the same thing and she's not even into performance driving or such.
I don't recall the Premium AWD feeling
slow. Not trying to say it's a problem. Just it was clearly slower than our old Tesla, especially on the highway, and that wouldn't do especially for my wife these days. (Driving a Tesla has spoiled her, she was driving a 4cyl slushbox when I met her.
) Also neither of us liked how floaty the rear got on the highway. GT PE suspension 100% solves that problem though. Honestly we only tested a Premium AWD because that was the best Mach-E the dealer had available, we would've gone straight for the GT PE if they had one. We liked the Premium AWD enough that I then sought out a GT PE to test! In fact the GT PE was my wife's favorite non-Tesla car we tested. (Polestar 2 Performance was mine.)
We all know now Ford's 0-60 numbers don't tell the whole story for the Mach-E. The 0-60 spec says GT PE will trounce an M3LR or MYLR, and that is true for 0-60...but the car falls on its face soon after that. Highway acceleration is where all these cars struggle the most, but the Mach-E has it worse than the 3/Y. Highway acceleration does matter to us.
