Audi A6: NEDC figures, lists 2010–2015

195 versions of the Audi A6 in the Vehicle Certification Agency lists 2010–2015, with combined economy of 25.9–64.2 mpg.

All figures on this page come from the NEDC test. NEDC was the official test before WLTP. NEDC figures are noticeably more optimistic, so do not compare them with WLTP figures.
