Comet Run (2) - S1.E15

By the second day of the race, both the Mach 6 and Chim-Chim get smashed by a canyon avalanche overnight. Speed uses his wits to go forward by using the natural elements to their advantage. At first, they think Zile tricked them into going the wrong direction. But they soon discover that it was Ranford who caused the avalanche and wrecked their car... and that his Eco-car is only keeping the emissions building up inside the front hood and he is actually storing leaded gasoline in Ranford Cola bottles to use for later, proving him a complete fraud.
