The AUDI A6 (2008-11) 4DR SALOON 3.0 TDI QUATTRO S LINE is a large, premium four-door saloon, aimed at buyers wanting executive-car comfort rather than a family hatchback or SUV. Its discreet styling and S line trim give it a sportier edge, while four-wheel drive adds confidence in poor weather. With a strong diesel engine, the A6 suits regular commuters, business users and families covering longer distances, offering a roomy cabin and relaxed motorway manners. It feels more composed and substantial than mainstream saloons, and competes with the BMW 5 Series and Mercedes-Benz E-Class; the Quattro system is a distinctive advantage for assured grip.
