the 1970 BP Canadian Economy Run overall winner was a 71 Demon with a stick shift, and in the competition Sir Stirling Moss was driving a Corolla.

The results were determined by multiplying each competitor’s actual miles per gallon by the car’s weight in pounds divided by 2000.

There is an account of this event in the November 1970 issue of Canada Track & Traffic.
