Audi believes the RS6 allroad will sell relatively well in markets where the roads are less than perfect.

The open-top model has been met with stronger demand than the 675LT ‘Longtail’ coupe.

The S550 is prone to charging-system malfunctions, while the E350 poses a fire risk from leaking fuel.

The top Platinum Reserve trim pushes the price tag above $60,000.
