2019 Audi S6 spied

The new Audi S6 sedan has been spied in southern Europe during development testing this week, ahead of an anticipated reveal later this year. Spotted almost free of camouflage, we can distinguish this S6 prototype from normal versions of the A6 sedan thanks to the more aggressive bumper treatments front and rear, larger air intakes, along with the quad-tipped exhaust out back. There's also lowered suspension, bigger wheels and bigger brakes compared to regular A6 models.
