How this list is made

Shorter bar, less energy per mile. Bars are measured from zero against the top value; the dark tick marks the average of all 21 ranked here.
Scores are John’s, shown only where he has scored a car, and they don’t affect the order. How John scores.
Each car’s page lists the source of every figure and when it was last checked.
