Even though, obviously, those designs still push/keep air away from the front and sides of the tires.
Any ideas how/why this works or why, in comparison, having a fairing directly behind the wheels may prove better aerodynamically? |
Interesting article. Thanks for the link. In the examples above, these cars are designed for huge downforce and tire grip which is often contradictory to low drag aerodynamics for better mpg. We hypermilers tend to drive at lower speeds with skinny tires tucked inside the bodywork. To answer your question, this works for this race car designer because it helps generate downforce. Exposed wheels will not help with a low drag design. Look to solar racers and salt flats streamliners to see cars designed for low drag aerodynamics.
