Research has found Volkswagen cars in Australia are consuming more diesel fuel following a product recall which was intended to cut emissions. Using "real-world" testing on the roads, the Australian Automobile Association (AAA) found a 2010 VW Golf used up to 14% more fuel on highways, with the average (including urban driving) being 7% more overall. Whilst there was a reduction in harmful emissions, tests showed nitrogen oxide emissions were still four times the levels recorded in lab testing. The AAA is calling for Australia to follow the EU in adopting real-world testing for emissions.
