what is fuel efficiency

Not everyone is clued into automotive terminology. Many people just want a working, functional vehicle; a vehicle that does exactly what it says on the bonnet. But there are times when learning about technicalities, such as fuel-efficiency, can prove invaluable.

And that’s the question we explore in today’s blog – what is fuel-efficiency and why is it important? The answer to this question will, or at least should, inform your decision when buying a new or used vehicle. In fact, it can help you save money.

What is fuel-efficiency?

At its most fundamental, fuel-efficiency refers to the ability of a vehicle to extract energy from fuel. The more energy a vehicle can extract from fuel, the greater fuel-efficiency the vehicle is said to have. Similarly, the less energy a vehicle extracts, the less fuel-efficient the vehicle is.

Simple, right?

Not everything can be listed as fuel-efficient, though. In other words, there are standards.

A vehicle is described as fuel-efficient if it is listed as having less than 6-liters per 100km (or less than 16.5km per liter). This standard prevents car manufacturers from listing their vehicles as “fuel-efficient” in cases when they quite palpably are not.

It means that a vehicle needs 6-liters of fuel, or less, to travel a distance of 100km. It depends on the type of engine, too. In general, diesel engines are more fuel-efficient than petrol engines. They use compression ignition, which extracts more energy than spark plugs.

Though these statistics appear dry, they have clear implications for drivers.

Why is fuel-efficiency important for drivers?

Because less fuel is required to cover a journey, fuel-efficient cars save more money for drivers in the long-term.

Even a 1-liter difference in fuel-efficiency pays dividends – often amounting to hundreds if not thousands of dollars (depending how much you drive, of course). So, the next time you enter a car dealership, be sure to ask your seller about the car’s fuel-efficiency.

It could make all the difference to your purchase.
