What is Fuel Economy and Why is it Important
What is Fuel Economy
To understand fuel economy we have to understand fuel consumption. The amount of fuel a vehicle uses is measured using a ratio of distance traveled per unit of fuel used. In South Africa this is measured in litres per 100 kilometres (L/100 km)
There are a number of factors that influence the amount and speed of fuel a vehicle uses, such as the vehicle’s engine parametres, weight, aerodynamic drag, rolling resistance, mechanical resistance, etc.
While all the factors that influence a particular vehicle’s fuel efficiency is important in the overall measurement,other dependencies come into play once the vehicle is taken on the road. Much like human beings, cars need oxygen to power. At sea level, the oxygen levels are lower therefore most cars, unless they’re turbocharged, produce less power. Temperature also influences the amount of oxygen a car can intake.
Why is it Important
Saves You Money
According to research, the petrol price has doubled every six and a half years since the 1980s. This trends shows that the petrol price in Gauteng could amount to R28.32 per litre by the middle of 2020.
More and more, South Africans will need to think more carefully about fuel economy when buying a car, and making this decision based on our lifestyles and driving requirements.
Reduces Environmental Impact
In the US, cars and trucks account for nearly one-fifth of all US emissions. Much of the carbon dioxide that is emitted comes from the extraction, production and delivery of fuel, although the bulk of it is attributed to the consumption of that fuel and the resulting exhaust fumes.
Fortunately, today’s cars are manufactured with fuel consumption as a major consideration, and choosing a fuel-efficient car is easy compared to a decade ago.
Reduces Oil Dependence Costs
The volume of crude oil produced will eventually begin to drop while the need for fuel increases. South Africa has become more and more dependent on imported petrol and diesel. A dependence on oil is a risk to our economy and we should bear this in mind when making car buying decisions.
While the factors that influence fuel efficiency play a significant part, perhaps more importantly is the one that controls thevehicle. Driving style can have a huge impact on fuel consumption. For tips on how to make every drop count, read our summer fuel saving tips.
