Audi, Volkswagen have been warned by the advertising governing body the Advertising Standards Authority.
The ASA have sent out a warning to all car makers that they need to take care and ensure that the way in which fuel economy figures are quoted are made much more clear.
This is to ensure that members of the public and prospective customers are not misled.
In fact the ASA have said that from now on car manufactueres have to state that figures are quoted from real driving situations and not from controlled driving tests.
The agency enforced the rule after a compliant from a Volkswagen Audi customer.
The customer complained that they had seen an advert for an Audi A3 in which the ad stated that “The Audi A3 1.6 TDI is the most fuel-efficient Audi ever returning a quite remarkable 68.9mpg on a combined cycle”.
The customer was so impressed that they bought the Audi to find that they could not achieve any thing like the promised fuel economy.
The ASA found against Audi and ruled that the advert was misleading.
A spokes person for the ASA is reported to have said “We considered that it was unlikely to be clear to the average consumer that the figure quoted was based on a standardised test and was not necessarily representative of what they would achieve when driving the car themselves. For that reason we considered that Volkswagen Audi should have qualified the figure to make clear to readers that it was based on an EU test for comparative purposes and may not reflect real driving results.”
