The Audi A6 4.2 Sedan features the V8 normally found in the larger A8 Sedan. The 4.2-liter engine produces 300 horsepower and 295 pound-feet of torque, channeled through a five-speed Tiptronic-controlled automatic transmission. A 60 month 100k mile extended powertrain warranty is included in the price of the vehicle for coverage from costly breakdowns between service intervals. Beyond the engine, the 4.2 also comes with more aggressive styling, bigger wheels and tires and more standard equipment. This system constantly monitors the grip at all four tires. When one of them starts to lose traction, the quattro system automatically applies power to the tires with the most adhesion to the road surface. As extra precaution, Audi's Electronic Stability Program (ESP), standard on the sedans, applies brakes to the misbehaving wheel and gently points you back on your course. With guaranteed credit approval for good, bad or no credit customers this vehicle is easily attainable. The A6 is an enticing choice in the hotly contested luxury sedan class.
