Frozen Rush, the Pro4 race sponsored by Redbull, was the first ever head-to-head Pro4 race held on the slopes.

The event is every adrenaline-junkies dream and draws thousands of spectators from across the country. It's hosted by Sunday River Ski Resort, where skiers and drivers brave the elements side by side.

Eight drivers competed in this year's race in specially-built trucks with supercharged engines. The 900 horsepower beasts ripped through turns and hit jumps - flying up to 200 feet through the air.

This year’s champion, Las Vegas native Bryce Menzies, says the feeling on the track is chaotic. "You have so much adrenaline that when you go back and watch the tape - there's a lot of moments where I am like that's just insane. I don't know how I am doing that or why I'm doing that, but it's so much fun."

The trucks go up to 100 miles per hour while hitting jumps, taking turns, and battling ice patches and whiteout conditions.

Last years Frozen Rush champion, Ricky Johnson, says racing downhill poses a serious challenge. "Normally we don't race that much downhill", he adds, "If we crash with a 4,000 lb truck I have no idea how long its going to take us to stop."

Drivers and their crews admit the extreme elements put their trucks to the test. Temperatures dropped to negative twenty during practice runs on race day, making it tough for drivers and their engines.

Tanner Stevens, the chief mechanic for pro racer Brian Deegan, says the intense elements change the game. "The biggest thing is keeping them warm. Not only the driver but the engine. Keeping the oil thin enough to go through the motor efficiently and stuff like that."

The event features Pro4 trucks outfitted with special studded tires designed for mega traction.  

"This has got the motor of a sprint car, the suspension of a desert race truck, but it’s got a special 35-inch BF Goodrich tire with ice spikes in it," Johnson said.

Stevens, and the fans, just can't get enough of the sound.

"When you hear these things roaring, 900 horsepower, naturally aspirated, these things just sound really, really mad going up those hills out there."

A Redbull spokesperson says the trucks plan to be back on the slopes next year.
