Consumer Reviews for the Audi A6

2019 A6 is fun to drive: 1 year update
Mr. Mike, 04/14/2019
2019 Audi A6 3.0 TFSI Premium Plus quattro 4dr Sedan AWD (3.0L 6cyl Turbo gas/electric hybrid 7AM)
I wanted to update the review of my 2019 A6 premium plus with the 3.0L engine, sports suspension and adaptive cruise technology. The car remains the most fun to drive vehicle I’ve ever owned. The new MMI that appeared radical a year ago is now so familiar. I love the ability to toggle and change info on the screens. I couldn’t imagine
going back to the old push knob that seems archaic … without a touch screen. Engine acceleration in sports mode is phenomenal. Maybe a bit of lag in automatic mode at low rev but not a big issue for me. Handling is superb and the cabin is very quiet, except for an annoying rattle from the rear sun shades that I would not order again. With snow conditions, the car handled beautifully even with streets that were not plowed well. FYI, my Pirelli P Zero tires performed well but only gave me 18K miles.
