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
