To understand fuel economy we have to understand fuel consumption. The amount of fuel a vehicle uses is measured using a ratio of distance travelled 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 a vehicle’s engine parameters, weight, aerodynamic drag, rolling resistance, mechanical resistance, etc.
While all the factors that influence a particular vehicle’s fuel efficiency are 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 Fuel Economy is Important
Saves You Money
According to research, the petrol price has doubled every six and a half years since the 1980s. 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.
While the factors that influence fuel efficiency play a significant part, perhaps more importantly is the one that controls the vehicle. Driving style can have a huge impact on fuel consumption. To make every drop count, read our summer fuel-saving tips.
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. Dependence on oil is a risk to our economy and we should bear this in mind when making car-buying decisions.
Increases Energy Sustainability
In order for future generations to meet their energy needs, fuel sources should be developed from renewable resources that is clean and efficient. These fuel sources must be also used wisely and optimally without wastage.
Most road vehicles run on oil as their fuel source, and while there doesn’t seem to be a dire shortage just yet, no one knows exactly how long this source will last. This is why we as drivers must play our part in ensuring energy sustainability for our children by adopting good driving habits and keeping your vehicle in good driving condition both mechanically and electrically.
