The Audi S5 is the perfect modern foil for a strong but silent Humphrey Bogart. The charcoal gray exterior drapes over the well-toned muscular body like a fine wool suit, perfect creases and sculpted surfaces. Carved rims set off gentle flairs for the fenders emphasizing the understated nature of the beast. Thoughtful touches such as simple heater/air-con/radio controls, fitted seats in burnt orange leather, well matched plastics that feel just right, an electric lumbar-support that is well-padded offering excellent support. If the devil is in the details then Audi has spent the time to get them right as few have.
