Ep. 51: Seorang miliarder mensponsori balapan global untuk emas dan tangan putrinya dalam pernikahan.
A billionaire, Mr. Karat Goldminter, sanctions the Around the World Grand Prix, a racing competition involving open wheel race cars, rocket boats, airplanes, submarines, snowmobiles, and finally the preferred race cars of each entrant; the race begins in Los Angeles and ends in Tokyo. Mr. Goldminter is offering a large amount of gold and marriage to his daughter Lovelace to whoever wins the race. Lovelace and her guardian Oscar enter the race to teach her father a lesson because she does not want to be married. Speed and Sparky are in the thick of things, when Team 4 cheats to win, including having spikes come out from their hubs. Lovelace wrecks her boat on the first water leg and Speed saves her from sharks. In the air, Team 4 uses both a blade and a long cable to knock several planes including Speed's out of the sky.
