Asked by Tim Nolan.
I read with interest Mark Pearson's comments regarding the fuel consumption of his Hyundai i30 diesel, as I too have one and have had a similar experience with it. It was promoted as doing a little over 4 L/100 km, but mine consistently averages 6.1 litres/100km.
When I took delivery of my new car the dealer went to great pains to emphasize the great fuel economy of this engine and I was told that this would improve as the vehicle was "run in". I have now done in excess of 30,000 km and it?s averaging 6.2 L/100 km. The dealer has told me they can find nothing out of the ordinary, but did replace my fuel filter at the cost of $100, which has yielded no improvement. They gave me a few sheets of paper to keep a log of the fuel I use, so they can check next time I take it in. I really think their promotional figures are just advertising and should be taken with a grain of salt so to speak.

We contacted Hyundai on Mark Pearson’s behalf and we received the following from a company spokesman:
“Fuel consumption figures displayed in accordance with ADR 81/02 are based on a static laboratory combined city and highway cycle test. They are not tested on the road. As a result, actual fuel consumption will vary. This is due to a combination of driving conditions, driving style as well as the condition of the vehicle. (e.g. air-conditioning, fuel type/quality used, weight, tyre pressures, wind, average speed, etc.).
These figures are therefore most useful to compare the relative performance of different vehicles – they all undergo the same test. The average motorist will experience consumption of approx 15-35 percent higher than what is stated on the fuel label due to the conditions that the laboratory test cannot simulate. Mr. Pearson’s vehicle is just over one month old, optimal fuel consumption figures are not likely to be achieved until the vehicle has travelled 10-15,000 km.”
If you apply the maximum variation Hyundai quotes you would get fuel consumption of a little over 6 L/100 km, which is about what he gets.
