Cardiff, Wales - Jeep guys love nothing better than to showcase their off-road driving credentials, but even by their standards this stunt was extreme.
They challenged Olympic snowboarder Aimee Fuller to drive a Renegade Trailhawk up and down an Olympic-standard white water rafting course.
Lets put some numbers on that:
The Olympic course at the Cardiff international White Water Centre is a 250 metre man-made white-water rapid that drops 10 metres from top to bottom. More than four tons of water - close to three times the weight of the Renegade - rushes through it every second.
That's enough to fill an Olympic-sized swimming pool in 10 seconds, or 14.4 million litres of water per hour. Even in a white-water kayak, it's not for the faint-hearted.
"I'd never done anything like this before," admitted Fulller, 24, "so when I arrived and saw the power and heard the noise of the water I was nervous."
"But once I'd driven into the course and got through the first few drops I started to relax and enjoy it.
"It's pretty cool to say I was the first person ever to drive a car down a white water rafting course, not something you do every day."
