The Secret Racing Test Tunnel No One Wants to Talk About

Larry Webster for Road & Track has the skinny on motorsport’s Area 51, a place steeped in legend and lore. A secret tunnel used to test race cars in perfect secrecy and—most importantly—near perfect atmospheric (viz. aerodynamic) conditions.

And then I was at the bottom, standing on an old roadway with weeds sprouting through the cracked pavement. I was staring at a new, shiny silver, domed structure that ran along the road for about 300 yards and ended at a decaying tunnel entrance. A stack of slick racing tires stood nearby, the final clue that I had found the place that symbolizes all that is fantastic about motorsports. Now I just had to figure out how to tell the story.
