GM designer John Cafaro says any good designer “has aerodynamic solutions in mind” the moment they begin work on a new project. Lift and down force are particularly important at higher speeds while too much drag can greatly reduce performance and fuel economy at the same time. GM has taken a number of steps in designing the new 2013 Malibu to reach a coefficient of drag of 0.29, equal to some of the world’s best sports cars. These include rounded bumpers and front fenders, improving air flow around the grille, and slightly smaller side mirrors.
