What better way to test the Audi A6 plug-in hybrid than to take it 3500 miles across France and Spain visiting luxury chateaux, villas and sublime art exhibitions?
One rainy morning I set off, with the Audi A6 hybrid fully charged (39 miles range) and gassed up to the max, headed for Dover. The idea being to test the Avant over long distances for ease of use, mpg, drivability, handling, speed, space and comfort.
