CNBC’s “Jay Leno's Garage” is a star-studded, action-packed exploration of all things automotive. Leno and his celebrity friends cross the country in celebration of anything on four wheels - from extravagant supercars to the wildest art cars, never forgetting that it's the people behind the wheel who provide the real stories.

In this episode, Jay Leno explores some of the world’s toughest vehicles. First, he takes comedian Kevin Hart on a near-deadly ride in one of the most outrageous off-road vehicles in the world. Then, he puts Storm-chaser Reed Timmer’s “Dominator” stormproof vehicle to the test against a jet airplane. Later, he meets some off the toughest drivers in the world— injured veterans who use high-speed racing as rehabilitation. And finally, Jay pushes the world’s fastest armored car -- and himself -- to the limit.

“Jay Leno’s Garage” is produced by Original Productions, a Fremantle Company, and Kitten Kaboodle, with Jay Leno, Jeff Hasler, Jeff Bumgarner, Ernie Avila, Brian Lovett and Abby Schwarzwalder as executive producers. Adam Barry is the executive producer for CNBC.
