A Correct answer
Explanation

At higher speeds, aerodynamic drag becomes the dominant force opposing vehicle motion. At 80 km/h (approximately 50 mph), roughly 50-60% of engine power is used to overcome air resistance. This percentage increases dramatically with speed - at 100 km/h, over 80% of fuel consumption can be attributed to overcoming wind resistance. The statement is essentially correct for typical passenger vehicles at highway speeds.
