Been a bit quiet here lately, people mostly sticking to road rules and using the search button to help decide on a car to buy, so I thought I would throw out a question that was sparked by a conversation in another thread about fuel/energy consumption stickers and range per tank/battery.
As a community, I thought it would be interesting to know how our vehicles compares to our car's original fuel consumption sticker. This can apply to all vehicles that you use as your main mode of transport. Doesn't matter if it is petrol, diesel, hybrid or EV, as by ADR compliance, all of these vehicle have to come with some form of fuel consumption figures.
Now, if you don't know your car's fuel consumption figures as per the sticker (usually in l/100km), you can always look it up using the Green Vehicle Guide and pick "Advanced Search" and fill in your car's details (The site is only for cars from 2004 onwards.)
You should have three figures: Urban, Extra Urban and Combined (In l/100km or Wh/km for EV's)
Urban refers to how the vehicle performs in an urban environment (stop/start, low speed city driving)
Extra Urban refers to relatively uninterrupted driving on inner city highways/bypasses/toll roads/outer city limits and intercity highways/freeways.
Combination is a mix of both urban and extra urban driving.
To work out your consumption, take the average size of your cars fill up in litres and how many km that tank usually gets you and bang it into this equation;
km traveled on a tank / litres in tank = km/l
(ie: 620km / 55l = 11.27km/l)
Now, to convert it to litres/100km; (as used by the labels)
100 / km/l = litres/100km (same as on the sticker)
(ie: 100/11.27km/l = 8.8l/100km)
So, pick your main car you drive, pick the main mode driving conditions and let me know in the comments if it's worse, better or spot on compared to the label and whether it's better or worse because of how you drive (being a Lead Foot or Sunday Granny…)
In you want any heavier reading on how vehicles are tested, you can read the relevant ADR 81/02 here
