Aston Martin DB11 Aeroblade

Like any high-end performance car, the Aston Martin DB11 has to generate downforce, but since it's a luxury Grand Tourer, it has to do it without wacky-looking bodywork. Aston has come up with a suitably elegant solution–air is channeled in through open bodywork in the C-pillar, and exits through a tiny opening on the rear decklid. It's a similar concept to the flying buttresses on the Ford GT, but much more discreet.
