When Mercedes-Benz began to contemplate its next generation of high-efficiency small cars, it sought aquatic inspiration. But instead of considering obvious undersea hot rods like sharks, the Mercedes team turned to a fish that resembled a car: the tropical boxfish. A native of the Indo-Pacific region, the Ostracion cubicus is surprisingly slick. Wind-tunnel testing of a clay model revealed a drag coefficient (Cd) of just 0.06, startlingly close to the ideal 0.04 of a water droplet.

Most tents are designed to fend off the wind, but The North Face´s Spectrum 23 invites it in through the front door-and ushers it right out the back. Built with a conspicuous awning that funnels wind through vents in the dome, the Spectrum ($260; thenorthface.com) can withstand 130mph winds, making it the strongest in the industry (100 mph is the previous best rating).

Nike's new speed skating suit, which promises reduced drag, will debut on United States, Dutch, and Australian teams during the 2002 Winter Olympics.




Whereas previous speed skating suits used only one textile, Nike's suit employs six -- each specific to the aerodynamic properties of that body area.




Developers used body-mapping technologies to study movement, and the effects of natural and artificial elements on those movements. Wind tunnel testing helped determine specific aerodynamic properties optmized by the different fabrics.
