trail car

In 1960, in the second Daytona 500, Mr. Johnson discovered the draft — the aerodynamic phenomenon in which two cars become faster when a trail car tucks behind a lead car.

During a particularly slow night a couple of weeks ago, Mitchell drove a white 1995 Chevy Corsica, a trail car, with his cousin Cody Kidd, 19, from Belle Fourche, who would act as his trail-car driver.

After three weeks of using his own vehicle, Mitchell bought a 2005 Honda Accord to use as a trail car for the business.

The riders scrambled into the “trail car” assigned to follow the target and disappeared into the traffic of the Imam Ali Autobahn.
