Car MPG

What is Your Car MPG?

MPG stands for ‘miles per gallon' and refers simply to that, how many miles you can drive your car using a gallon of fuel. Officially there are 3 measures of MPG (in the UK) as the exact efficiency of your car will depend on your driving practices. You can find a description of the different measured of car MPG at the end of this page.

What is my car MPG?

Use the form below to find out your car MPG, we quote the combined fuel consumption figure as we believe this gives the best indication of a realistic MPG fuel efficiency. The results of the form also show the car tax band that your car has, along with estimated car tax costs. Basically the lower your car's MPG, the more tax you have to pay. Please note that at present we do not cover all cars on the market.

 

We are also collecting REAL WORLD mpg values, so if you know how many miles to the gallon your car typically gets then please tell us by using the Add Your Comment button. Please include your car manufacture, the model number, year, fuel, engine size, current mileage your driving style.... and of course the MPG!

 

MPG FUEL CONSUMPTION TEST (Directive 80/1268/EEC as amended by 2004/3/EC)

The current test has been agreed internationally and provides results that are more representative of actual average on-road fuel consumption than previous tests. There are two parts: an urban and an extra-urban cycle. The test cycle is the same as that used to determine the official exhaust emission classification for the model of vehicle in question. The cars tested have to be run-in and must have been driven for at least 1,800 miles before testing.

The tests are performed on a rolling road under controlled ambient conditions. Although this gives a highly controlled environment it does not take into account the wind resistance of the car, or any efficiency losses that occur during cornering and climbing hills. However overall these tests do come close to the real-life MPG that people obtain during normal driving.

MPG Urban cycle

The urban mpg test cycle is carried out in a laboratory at an ambient temperature of 20°C to 30°C on a rolling road from a cold start where the engine has not run for several hours. It is intended to mimic the short car runs that are often performed, e.g. the school run or going to the supermarket. In practically all cases the urban cycle will give the lowest MPG figure.

The cycle consists of a series of accelerations, steady speeds, decelerations and idling. Maximum speed is 31 mph , average speed 12 mp and the distance covered is 2.5 miles.

MPG Extra-urban cycle

The extra-urban mpg cycle is conducted immediately following the urban cycle and consists of roughly half steady-speed driving and the remainder accelerations, decelerations, and some idling. Maximum speed is 75 mph , average speed is 39 mph and the distance covered is 4.3.

The extra-urban cycle is intended to mimic the longer journeys which typically include dual carriage way or motorway driving. As the car has been allowed to warm up and spends a good deal of time in the higher gears, the MPG obtained is higher than for the urban cycle.

MPG Combined Fuel Consumption Figure

The combined figure presented is for the urban and the extra-urban cycle together. It is therefore an average of the two parts of the test, weighted by the distances covered in each part.

"What a load of rubbish"

Bernard

"New Astra 1.6 petrol manual. EEC test says around 44mpg combined; I get 42mpg averaged over 10k miles. My last similar Peugeot 307 1.6 petrol did 38mog, so the Astra is quite acceptable despite being 2 mpg below test target."

Stan

"It looks to me that the advertised mpgs have little to do with reality. So what's the point if you can't rely on them?"

S C Tracey

"i have a ford fiesta titanium econetic. car has done 700 miles so far. average journey is 11 miles motorway, 11 miles urban). the sales pitch gives : urban - 61.4, extra urban 88.3 and combined 76.3 reality is that the combined so far is 42.4mpg and that is trying to drive as efficiently as possible in the city not impressive, especially when factoring in the addition cost of diesel "

"Hyundai i10 1.2L Comfort Automatic, reg Sept 2010, mileage 1850. Town driving (urban cycle) Manufacturers figure = 38.7 mpg ACTUAL figure = 28.8 mpg (25% less) Disgusting!"

D Jolly

"We have a Ford Fiesta "econetic". Its Urban is stated as being 61.4mpg in Ford brochures. In reality we've been getting on average 50.58mpg. This is only 82% of what is should be on the urban cycle. Are manufacturers being truthfull about their figures now as so much rests on these figures?"

Jon

"I entered my car and manufacturer in order to find my average MPG, but what do I do next. The page is a bit of a mess with adverts and blank spaces and no obvious indicator or what to do."

Richard

"I have a 2010 1.6 TDI, S-Line (7-speed S tronic) Audi A3. The advertised MPG for the car are supposed to be: Fuel consumption, mpg (l/100km) Urban: 62.8 (4.5) Extra Urban: 72.4 (3.9) Combined: 67.3 (4.2) However I am only getting a range between 35-41 mpg on average, (mostly its about 38.5 mpg) which is approximately only 58% of advertised combined fuel consumption. "

Scott Clacher

"My Jetta is a 1.4 TSI and is not listed, neither is my previous 1.6???"
