1972: Front and rear spoilers

The Porsche engineers worked unceasingly to make the entire 911 package even better. This included improved aerodynamics – which was taken into account in 1971 with the first front spoiler, based on knowledge taken directly from the field of motor racing. It was used on the 911 S and later on the 911 E. The spoiler guided the air away to the side, thus reducing the lift on the front section. It improved directional stability and made the car easier to handle. The 911 T was also fitted with the front spoiler one year later. The 911 Carrera RS 2.7 introduced the rear spoiler – it featured the distinctive “ducktail” and was one of the reasons why this type became a cult car. The next rear spoiler that could genuinely be called “historic” was that on the 911 Turbo. Its large, flat design adorned the vehicle and, in addition to its reliable function, it was also a statement about the power and the speed of the Turbo. To briefly explain the technical principle: spoilers at the front and rear enhance the vehicle’s aerodynamics and improve directional stability, braking and steering characteristics, cornering behaviour and the car’s response to cross winds, especially at high speeds. They guide the air around the outside of the vehicle (front spoiler) and prevent too much air underneath the car which would result in unnecessary lift and significant turbulence on the underside of the vehicle, especially if it is not lined and therefore has clefts. The role of the rear spoiler is to discharge the air flowing around the vehicle at the right place – the spoiler lip – with as little turbulence as possible.  The rear spoiler being designed as a wing in the form of an upside-down aeroplane wing makes it possible to increase the contact pressure on the rear wheels and therefore generate downforce. The vehicle’s even air flow and the controlled negative lift increase the top speed and reduce fuel consumption.
