A new report has found the average Australian consumer is buying fewer cars than in previous years and more than half of them are in fuel-powered models.

Consumer Reports has compiled a list of the 50 largest cars in the world and a report shows the average driver has been buying fewer than one car per year.

It is a record low for Australia.

In a study published on Wednesday, Consumer Reports found Australians have been purchasing fewer cars since 2016.

The new findings are based on a review of data from more than 4,000 US consumer reports.

“There is no question that consumers are buying fewer vehicles and more fuel-efficient vehicles in recent years,” said Richard Brown, president of Consumer Reports.

He said the data was “unusual” and the number of vehicles purchased was lower than it has been in years.

It was also the lowest number of fuel-saving vehicles ever recorded.

But the report said it was unsurprising.

Mr Brown said there were “a number of factors” behind the drop.

There was less incentive to buy a new vehicle, the price of fuel had dropped, and there was less of a focus on fuel efficiency, the report found.

Consumer Reports is calling for a “more robust and more transparent regulatory environment” to increase the consumer’s confidence in the fuel-efficiency of cars and trucks.

Many people were reluctant to buy fuel-emissions-trading products such as fuel cell cars because they felt the technology was too expensive, he said.

Fuel cell cars use a small amount of energy to run electricity instead of fossil fuels.

A fuel cell car is a car that runs on hydrogen fuel rather than gasoline or diesel.

As well as reducing CO2 emissions, the technology allows the vehicle to be charged at the pump when not in use.

More than three quarters of all new fuel-cell cars sold in the US last year were hybrids, the study found.

The report found that the average car bought in the UK was a hybrid, while in France, the average was a petrol-electric hybrid.

Australia is now on track to be the third largest market for petrol-powered vehicles by 2025, behind the US and the UK, according to Consumer Reports data.
