The course is downright diabolical. The margin for error is thinner than ever. The finale is nearly here. Go, drivers, go!

A few old favorites return to the course for a series of head-to-head battles. The prize: a second chance at glory.

With the competition down to eight drivers, the track designers crank up the difficulty with a new obstacle that turns out to be alarmingly dangerous.

A new obstacle humbles the racers -- even one indomitable driver. Another contestant's overconfidence proves costly on the track.

As the knockout round begins, the drivers must prove themselves on a newly redesigned course. But not everyone's car survives the chaos.

The qualifying rounds continue with the craziest obstacle yet and six new racers. The standout is a 21-year-old nicknamed the Baby-Faced Assassin.

The amped-up drivers get their first experience on the course, but not everyone has what it takes to dominate behind the wheel.
