If that’s your benchmark, EV’s can average about 5MPH slower over very long trips at highway speeds than ICE engines. It’s worse on ultra long trips or if you’re doing 100+MPH trying to break the cannonball run record etc, but that’s frankly illegal anyway.
PS: As an edge case benchmark, a 2018 model 3 has done the New York City to Los Angeles in 45 hours and 16 minutes or 61.5MPH including breaks. I only see that time dropping as EV’s improve.
Sub 26 hours in an ICE averaging over 110 MPH and a top speed of 175 mph. That’s not just lose your license but head straight to jail territory.
But sure as I said, if that’s what your going for ICE engines currently have a significant advantage using current technology and infrastructure. However, in terms of capacity to do a real world road trip the difference is already minimal.
PS: Don’t forget electric trains do 375 mph and can maintain that indefinitely. Assuming EV is always just going to be a battery technology is far from proven at this point.
