As we should all know, Red Bull is no stranger to extreme motorsport, it came as no surprise to see them place eight Pro 4 racing trucks on a specially-designed race course on the hills of Maine’s Sunday River Resort to see who is the fastest on ice.

10,000 spectators braved single-digit temperature to witness motorsport getting an edge on Mother Nature and they were not disappointed with the fierce battles between eight of the country's best professional off-road truck drivers.

The racing proved to be intense from start to finish, with the final race pitting long-standing rivals Ricky Johnson against Johnny Greaves. With an extended four-lap final (all other rounds were two laps), Greaves lost to Johnson as he was penalised 5 seconds for gracing a race gate.

Watch the clip below to see the 900hp trucks, with specially studded Mud-Terrain BFGoodrich tires, go through the course (complete with jumps, slaloms and more), sideways mostly.
