The latest results cover a mix of SUVs, passenger cars and utes, with 11 of the 21 vehicles tested delivering fuel consumption within 5% of lab test results, while eight exceeded their lab test fuel consumption by 6% or more. Conversely, the AAA found that two vehicles had on-road fuel consumption 10% to 13% lower than their lab results.
The four-year testing program the AAA has been tasked with will examine 200 cars, SUVs and utes, including electric vehicles, with EV testing protocols now in development.
Other carmakers in the AAA report were contacted for comment.
