Yes, but it's unrelated to highway versus city performance in electric/hybrid cars.
Driving under highway speeds is almost always more efficient due to wind resistance. But for ICE cars without regenerative brakes the losses from braking and idling hurt enough to give the illusion of freeway efficiency.
And the reason actual highway speed versus the estimates on the sticker are often so far off with ICE cars is that the test is based on 55mph max highway speeds with an average speed of 48mph. Meanwhile the speed limits on all the freeways near me are between 75 and 85, making actual performance way, way worse.
