The index measures “affordability” as the cost of a litre of petrol relative to a country’s average daily wage, while overall spend represents how much the average driver spends on petrol in a year, relative to the average salary.
According to the 2016 index, South Africa is ranked last – spending the highest proportion of the average salary on petrol in a year. However, as of April 2017, Mexico has claimed top spot, where 3.9% of the average annual Mexican salary is spent on petrol.
South Africans spend an average of 3.2% of their annual salary on fuel for their cars – while people in top ranked Venezuela spend a mere 0.02% of their average annual salary on fuel.
Amid rising fuel prices, consumers are being forced to do their homework before buying a vehicle. These are the most fuel efficient cars currently on the market.
