We all know that the McLaren P1's design was pretty much made in the wind tunnel, instead of by either McLaren's Frank Stephenson or the engineering team.

It is extremely important for Simone Origone, the world record holder for speed skiing at 155.9 mph, to absolutely minimize drag. When he needs to test how cleanly he cuts through the air, he goes to the wind tunnel at automotive design house Pininfarina.

Active aerodynamics have long ago filtered down from track cars to high-end sports cars, and are beginning to show up in everyday sedans. But General Motors has patented an idea to use shape-shifting materials to make them more efficient.

Jalopnik commenter Scoutch has a day job many of us might try for free: Building stuff in the labs of Mythbusters. Check out his take on what's it like to drive a Porsche 928 with its body bolted on backwards.

The Mythbusters crew and Popular Mechanics will test later this month the old claim that the Porsche 928 could go faster if driven backwards. To do so, they flipped a 928's body to face the wrong direction.

You know you’ve got a serious track Ferrari on your hands when even the taillights have been ripped out to make room for extra vents.

The BT46B—also known as the Fan Car—was a cunning Gordon Murray racer, designed to one-up the dominant Lotus 79 in the 1978 Formula One season.

A while back, Wert noted that underbody plastics serve a glorious and wonderful purpose. We found an example of this sort of thing in L.A., and it just happens to look awesome. Five bucks says you can't guess the car.

BMW Oracle Racing unveiled what it believes to be the world's largest wing on Sunday. Complete with flaps, the wing is a massive 190 feet long. The catch? It goes on a trimaran, not a car.

Excellent under-body aerodynamics will make the bottom of a car look as flat as the underside of a Hot Wheels racer. But looking awesome is obviously not the only purpose.
