第 8 集: Speed 和 Trixie 逃離猛獁車駕駛的追擊，並在 Cruncher Block 的礦坑隧道總部與他當面對峙。
Satisfied that Speed and Trixie are dead at the bottom of Lake Icy Chill, the Mammoth Car drivers continue the race. Through Speed's telescanner, he sees them leave as he reaches soil. Trixie now sends a message in the homing robot to Inspector Detector. Speed strongly suspects that the stolen gold is aboard the Mammoth Car. From his plane, Cruncher Block spots the Mach 5 back on the road. Speed and Trixie are fired upon at the refueling station. When they escape into a mining tunnel, they jump on top of a speeding trolley car before it crashes. Back at the refueling station, Spritle and Chim Chim sneak outside of Cruncher's airplane. They escape into the tunnel, which turns out to be Cruncher's headquarters. Speed and Trixie are both tied to a trolley loaded with three tons of dynamite connected to it. Racer X arrives and saves both of them. At the checkpoint, the Inspector searches the Mammoth Car. No gold is found there. When Speed reaches the checkpoint, Spritle and Chim Chim slip out to hide in the Mammoth Car. The Mach 5 and the Mammoth Car both cross the finish line and tie for first place. They continue at breakneck speed towards the shipyard. Spritle and Chim Chim both knock out the Mammoth Car’s driver, while Speed jumps in and then flees with his brother and Chim Chim just as the car causes a collision with an oil tank, causing it to melt into a pool of molten gold.
