New S6 saloon from Audi has further raised the benchmark as this time; Audi has made this luxury chariot even more powerful and efficient. Dubbed as more intelligent power, S6 now comes with cylinder on demand technology that returns better results on mileage front. Add to this efficient twist, the virtues of lightweight construction, energy recovery and stop-start system, new S6 zooms ahead of its rivals with huge margin. Striking feature of new S6 is cylinder deactivation that allows the engine to completely shut-off 4 cylinders out of 8 on part throttle input. This doesn’t translate into any perceivable difference in performance as S6 continues to run smoothly and powerfully though there are considerable gains on fronts of mileage and emission of waste gases. As before, S6 styling is dominated by large single-frame grille that houses several horizontal chrome slats. In profile, its demeanour is characterized by urging-forward theme that is accentuated by crisp body lines and character streaks. Cock-pit cabin, sports seats and MMI navigation system are interiors highlight which continues to offer class-leading feel of oomph and luxury.
