Let's compare EV and gasoline efficiency (autonomia) and range (in km) across a wide range of speeds (velocità), normalizing to 50 kph/30 mph. We see that both lose range with increased speed in the same way. Energy is energy, aerodynamics is aerodynamics.
Also worth noticing is that 1 L of gasoline contains about 9.5 kWh, so we see that gas cars only do about 1 km/ kWh at 130 kph / 80 mph, compared to 5.6 km/kWh for an EV.
Gas cars are pathetically inefficient, and it's only the ease of tankage that gives them a long range, using about five times as much energy as an EV does.
