Adjust the slider to match your daily driving habits. City driving involves stop-and-go traffic under 45mph, while highway driving represents sustained speeds over 55mph.
The Brick Effect: Highway Speed Penalty
EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Because the Standard Pickup Trucks has a large frontal area, expect your real-world highway fuel economy to drop by up to 25% at high speeds.
