Where Tesla get range bang-for-the-buck is in aero drag coefficient. They didn't go for good looking, they went for the aero crown. A Mach-E just pushes a lot more air out of the way than a Model Y, and at highway speeds, that's a big deal. That's where the "efficiency" war is won.
It's also why if you just drive the Mach-E and Model Y around at "city" speeds, the range will be surprising similar. The Mach-E larger battery may be enough to actually tip the scales its way, despite the aero (and battery weight) handicap.
Fun BEV wars ahead...
Interesting, but I don't think that's entirely accurate -- yes, the Tesla models have a measured lower drag coefficient. But, the Mach-E and the Tesla Model Y both undergo EPA range tests on a dynamometer, where there is no aerodynamic drag.
I think the difference there isn't enough to account for the range differences. I think Tesla simply has more years of experience in engineering a more efficient powertrain (through software!) -- something that Ford, through OTA updates, and subsequent model designs, will slowly but surely gain on.
