Aerodynamic resistance (“drag”) doesn't care about your transmission. The sweet spot is even lower with electric cars (especially with all the peripheral devices turned off). However, a modern mid-sized car with an efficient engine gets 40 MPG or more at 75 MPH, while a gas guzzler won't get such mileage at any speed.
