Which car has the most extreme aero from the factory?

Technological advancements have allowed car manufacturers to produce high-downforce cars without the need for big wings. The Aston Martin DB11 is a case in point. Through extensive testing Aston have developed an ‘AeroBlade’ rear spoiler, which channels air from the C-pillars to reduce lift - thus no need for a heinous wing.

The problem is, we like big wings. Personally I love the Pagani Huayra’s active aero. At a standstill the car looks elegant and refined. But when the driver gets on it, the wings come out to play.

So, we want to know: what car, past or present, has the most extreme aero from the factory?
