See how unrealistic car fuel economy figures are, how they're changing & why it affects YOU!

Do you ever find it hard to meet the fuel economy figures quoted by your car manufacturer? You’re not the only one! That’s why changes are being introduced to review how fuel economy and emissions are calculated.

Want to find out what exactly’s going on? Watch my latest video to find out how the tests will be more realistic, what effect it may have on car tax, and (more importantly!) how it could help save you money!


Awkward haggling is a thing of the past with carwow. Choose your perfect car with our configurator tool and let the country’s best dealers compete over you.

It's nice to have motivated people, but the editor was a bit overexcited on this video

I would like to have physical contact with that RS4.

[KurlixRacerSsr]

Too overedited with those random clips.

[jamie_ar]

These little clips in the video and just the whole feel of this video is off. Trying too hard, carwow.

Who doesn't like saving fuel? Fuel is slowly becoming gold

[Kylirr]

damn the editor was very hyperactive today

[NuhanHidayat]

Did carwow just hire Seth MacFarlane as their new video editor? Please get back to old carwow style, with less cutaway videos

My Suzuki Swift is supposed to get around 50-60, and I get about 56.6 Mpg on average, so I'd say say the figure from Suzuki is pretty accurate.

To achieve the claimed numbers is in a way mostly a test of willpower. I owned a 335i for 11 years and it had a claimed 7.2l/100km and once when driving about 890 km in one run I achieved 7.3l/100 km and on the way back 7.4. I achieved it by accelerating moderately, obeying the speed limit, coasting whenever possible, never flooring it when overtaking. I also had a really good number for city driving for many years but during the last few years I didn't have the willpower but instead feeling like using the power in a more aggressive way, of course the range shortened.

Great video as always Matt.

I have owned three cars from new and compared the official MPG to real world (almost obsessively) on all of them. I've done that to the point of not trusting the trip computers (which are also out by about 10%) and instead by brimming the tanks and using maths.

I've come to the conclusion that there isn't a need for a new test. Real MPG figures can be calculated using a simple formula. Manufactures claimed MPG x 0.8 = real world MPG figures.

I'm not joking, it is surprisingly accurate!

[janukjayawardana]

pls don't add any small useless clips,
Mat your explanation is very clear and understandable.
more importantly it makes carwow less serious like other channels
keep up the previous work.

[DC-pefr]

Every car i've owned i've managed to easily get the claimed MPG, a-lot of people don't know how to drive efficiently

[MrJustin]

"Computer says no" :'D I loved Little Britain

What this video omits is that trip computers tend to be optimistic too. On my 2011 Polo 1.4 it's usually about 4 mpg over my brim to brim calculation: 43.2 versus 38.95 on my last fill-up (city driving in summer). Yet testers tend to take the trip readout as gospel.

[keijomattinen]

I wonder how reliable those trip computers are? I'm affaid those official figures would be even more off the mark if compared to actual fuel consumption.

[ronaldderooij]

I drive like a grandma, and I get exactly the fuel economy that my car should get according to the manufacturer. So, it is all in your right foot. Slow on the gas pedal and avoid braking.

This video made me chuckle. I've got a 2011 Jetta TDI with 300, 000 km, almost 200, 000 miles. I drive 150 combined miles every day to work and back. Part back road, part highway, part city traffic. I actually get over the estimated MPGs for my car. Which I believe is 34, and I get between 37 and 40 depending.

My wife has a 2013 Mazda CX-5, drives around a 50 mile round trip through city and side road, she also achieves equal to or above the rated MPGs of her car.

Cars will do the MPG they are advertised to do. Will do it quite easily in fact, so long as you're a smart driver.

Give yourself a bit of extra time when you go places so you don't have to speed. Know that when you start getting above 50 mph and on to highway speeds it is more efficient to run the A/C than have the windows open. The same goes in reverse, below 50 just open a window. Don't be a clown on the throttle, keep it smooth, and try to avoid hard braking.

What this nutsack doesn't take into account is it's how you drive that matters. When they get these mpg figures they do it by driving an empty stretch of highway at the speed limit, they don't take into account people being late and doing 100 mph and such.

They aren't posting false or unattainable MPGs, if they were it would be false advertising and they would be hit with heavy fines. They can prove you CAN in fact achieve these MPGs so long as you're not a knob behind the wheel.
