1971 Hot Wheels Sizzlers Track Sets Posted on August 10, 2021 (August 10, 2021) 1971 Sizzlers tracks came as 2 orange tracks and 3 black Fat Tracks. Of the orange tracks one was for North America and one for the United Kingdom. North America got the Highwinder Set The U.K. got the Pursuit Set The big advance for 1971 was the advent of Fat Track. This gave Sizzlers cars room to wind up and go! All 3 sets had an Ontario Motor Speedway theme. The Big “O” Race Set The California 500 Race Set The Super Circuit Race Set In subsequent years, no Sizzlers tracks proved to be faster than the 1971 sets
