The faster you go, the more your car has to overcome aerodynamic drag. That much is obvious. What might be more surprising, however, is that drag increases at the square of speed – if you’re going 30 miles per hour and accelerate to 60 mph, you’d expect to encounter twice the air resistance, but in reality, there’s four times as much. Slick aerodynamics are more important at higher speeds than anywhere else, and BMW has patented a solution that could make its wagons, hatchbacks, and SUVs even slicker on the freeway. And considering EVs like the iX3 are even more susceptible to wind resistance, the new tech could be a game changer for battery range.
