Porsche has big plans for the coming year, with more manufacturers resuming manufacturing and design operations around the world. The Taycan Cross Turismo looks great, but it’s the Porsche 911 GT3 we are most excited about. Which Car Australia received news about a Q1 2021 launch, a reveal which was to have taken place at the 2021 Geneva Motor Show. Although a date is great, there is more information that points to a Porsche 911 GT3 that is lighter, faster, and rawer than ever before. This is in large part due to some very radical aero.
This excerpt is from an article on Which Car Australia: “Why do aircraft carry the engines underneath the wings instead of on the top?” The reason is that the top of the wing on a plane is what speeds the air and creates low pressure. This results in lift. This area must be unencumbered. You can think of a racing car’s wing as an inverted airplane wing, and you will wonder why it took so long to see items with unencumbered underneaths.
This design was developed when racing regulations and rules limited the size of rear aero. Although the swan-neck design is smaller in width and chord, it recovers nearly 50 percent of the lost downforce. Although the actual production car won’t have the same amount of aggression as the Porsche 911RSR GT car the gains should be comparable.
