What is your average fuel consumption Litres per km?

What’s the average fuel consumption of a car?

On average cars achieve 84% of the official combined fuel consumption figure but this includes many older models when the test was more representative. Spritmonitor.de – a German site which calculates fuel economy based on users’ fuel purchase and mileage data. Fuel consumption figures are quoted in litres/100km rather than miles per gallon.

When do the official fuel consumption figures come out?

From 1 January 2019 all official published fuel consumption figures for new cars should be WLTP rather than NEDC. The first year VED for new cars is based on official CO2 emissions figures as is company car tax.

Why is there a gap between official and actual fuel consumption?

It seems that the more economical a car is to run on paper, the greater the gap between official figures and actual fuel consumption. This means you can’t even rely on official figures as a guide to relative performance. New car models have to meet a range of safety and environmental ‘type approval’ tests before they can be sold.

How to calculate the cost of fuel per mile?

For example, if you notice that your usually spend $0.15 per mile (15 cents per mile), then if you know you will be travelling for 200 miles, you can calculate the cost of the trip by multiplying 200mi x $0.15 = $30 for a 200 mile trip. Similarly, for km. Fuel efficiency, or fuel economy, can be a tricky concept.

Is there an optimum driving speed for fuel economy?

While there is an ideal speed, road conditions and gradients don’t often allow you to do that speed so you have to improvise and learn to adjust your driving according to the road ahead, a technique often referred to as hypermiling. Generally speaking, there is no one driving speed which is optimum for fuel economy.
