Luxury European sports cars often feature ‘active’ aerodynamics. In other words, the car’s ECU controls aerodynamics on the fly, moving components such as grille vanes, which can be motorised to limit or enhance the amount of air travelling through the part being manipulated. This technology has two major benefits. Firstly, it helps the engine to warm quicker, reducing harmful exhaust gas emissions. Secondly, it vastly reduces drag. Improved fuel economy and performance benefits? Where do we sign up?!
