So you’ve ruled out a hybrid luxury sedan for a number of reasons, mainly due to lack of solid performance. Your choices are now either a gasoline or diesel-engined machine, and although you do have some environmental concerns on your mind, being green isn’t a must. But still, saving money at the pump sounds nice. Audi
fortunately has two excellent solutions to this dilemma: the A6 TFSI V6 and the A6 TDI V6. While both have 3.0-liter engines, the familiar gasoline engine may have met its ultimate match in the form of this powerful yet efficient turbo diesel.
