What happens when you take a childhood classic, strap on two jet engines, and push it past its limits? The Hacksmith team decided to find out—by turning a GT Snow Racer into the fastest sled ever! After overcoming weather delays and safety challenges, they blasted across the snow at a record-breaking 107 mph (172 km/h), crushing the previous record of 42 mph (68 km/h).

Did they break the record? Oh, you bet they did—with enough speed to make Santa jealous! Check out the full video to witness the madness:
