The Audi A6 is often compared directly to its German contemporaries in the BMW 5 Series and Mercedes-Benz E-Class, both of which have a long history of sedan excellence and offer impressive style, tech, and quality for a price premium.
The Lexus GS is long in the tooth at this point and lacks the connectivity options of the Germans.
Jaguar’s XF is beautifully understated, and its powertrain lineup is excellent.
There’s even a wagon, if you’re into that.
Finally, the Cadillac CT6 is slightly larger than this competitive set but offers impressive semi-autonomous tech and engaging driving dynamics.
It will be dropped after 2020.
