Under EC laws, no car manufacturer is allowed to "advertise" fuel consumption - but they're obliged to publish the results of EC regulated tests which are generally accepted as unrepresentative - hence the need for HJ's Real MPG webpage.

The US tests are done to an entirely different test structure and no parallel can be drawn from Hyundai's case there.

Sorry to hear about the low mpg. The i10 and Kia Picanto share many engineered parts, I have the Picanto 1.0 Kappa engine which should deliver around 67mpg. Realistically I am getting around 45mpg which is allot less, this is with mixed driving some motorway and city areas. When the Picanto was brand new until it had done 2k miles I was getting 38mpg

You cannot assess the fuel economy of a new car until it has done at least 2,000 miles and in a diesel (which yours is not), 5,000 - 10,000 miles.

We have a new Nissan Juke which has done less than 1,000 miles. The average economy over those first miles has risen from 27.7 to 29.9mpg and I will not consider this representative until I have done 2,000 miles and then zeroed the trip computer.

Also remember that trip computers are not as accurate as manual calcuation of fuel use.

If most of your driving is in and around Leeds (as your name suggests) consumption will be high anyway, because of the usual congestion/road layouts. Take it for a leisurely cruise to the East Riding and it will probably be much nearer expectations. See HJ's real mpg data.

I believe that in the US Hyundai and Kia owners are being compensated using the difference between the over-stated fuel consumption and the correct fuel consumption based on the mileage done - so the actual amount of compensation to affected owners won't be that great.

We have a 2012 i20 which uses the same 1.2 engine as the i10 - covered just over 4200 miles now. Fuel consumption around the city streets of Birmingham (lot of stop/start driving which drags down the mpg) and we're getting around 38mpg - which given the circumstances we are OK with.

hi leeds lady.30mpg seems hard to believe i would say you should be looking at about 40-45mpg for this car.you dont say what sort of driving is giving you this mpg.what car did you have before and what mpg was you getting from that one while doing the same sort of driving,have you reset the fuel computer since you had the car,i have a hyundai veloster 1.6 that is returning 37mpg around town and the last tank full with some motorway driving included has given me over 40mpg,a new car will take time to bed in but from my experience your mpg should improve but only by a few mpg,let us know how you get on,,,,,,,,,,,,veloster,,,,,,,,

A friend of mine has had a bit of a suprise with a Hundai i30 Active - the this time better than he expected. He is getting 42-43 average (rural + town) out of a 1.6 petrol auto (with good old fashoined auto box). This is better than the official figures.

Must the i30 suprised me when I was a passenger in it- very smooth and refined.
