Tesla uses 2.4 kw per mile at highway speeds. The generator could keep up with that, since it does about 2.6 kw.
Gary thanks for the link.
I'm not sure how you came up with that, but your math seems a little goofy. 2.6 kw is just over 3 hp. It takes a lot more than 3 hp to move a 4000 lb car at 60 mph, regardless of how efficient it is.
My math came up a little different. I googled that the average Tesla uses 34 kwh per 100 miles at highway speeds. That's 340 watt/hours per mile. In one hour at 60 mph, you obviously travel 60 miles, so 340 watt/hours x 60 = power consumption rate of 20.4 kw. That equates to just under 28 hp, which sounds much more reasonable to move a 4000 lb car at 60 mph.
I think the confusion is in the difference between motive force required to move the car and how much energy the car uses in a certain distance. For example, after 7 years of driving an EV our lifetime average is 6.4 kilometres per 1 kwh of electricity. Which of course is different than what it takes to actually push the car down the road at 100 kph.
