>>1419826Both of you are not entirely right:
Electric vehicles often get better efgiciency in the city than on the highway.
Electric vehicles get the highest range at a low but constant speed.
>but whySimple, electric motors don't realy get less efficient at low loads like ICEs do and they have regenerative braking.
In the city you usualy don't go much faster than 50 km/h, aerodynamic drag isn't yet that high and regenerative braking makes you waste less energy on decelleration.
On the highway you are going about 130 km/h most of the time, aerodynamic drag makes up most of the entire resistance, making it a lot more resistance to overcome.
Since engine efficiency for electric vehicles is about the same in either case and braking doesn't kill as much energy, you can get more range in the city than on the highway.
>but why is it different for ICEs?There are mainly two factors different for ICEs here:
ICEs have terrible efficiency at low power levels and ICEs don't have regenerative braking.
That's why hybrids are a thing, they keep the ICE running where it is the most efficient and have regenerative braking.
Video kind of related, a Tesla driving at 90, 150 and 200 km/h on the Autobahn to measure how much electricity is required at the respective speed:
