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.

The Ferrari F430-based New Lancia Stratos is a mostly untouchable limited-edition plaything for the fabulously wealthy and well-connected, but that doesn't make watching final engine tuning of this gorgeous vehicle any less enjoyable. More below.

For 30 years, engineers in GM's Aerodynamics Laboratory have improved automotive fuel economy with this, the world's largest wind tunnel designed for automotive applications. This week, on the tunnel's 30th birthday, here's an amazing look inside.

The inside of a wind tunnel is a very cool place. But this is a Ferrari wind tunnel, so you know that even the outside has to look cool too. [via Sharonov]
