The Audi A6 is most often compared to the Mercedes-Benz E-Class and BMW 5-Series, other mid-size luxury competitors imported from Germany.
Both the E-Class and 5-Series have more permutations than the A6 (for now) and offer plug-in hybrid variants all the way up to snarling V-8s.
The Lexus GS is comparatively old and lacks connectivity and comfort compared to all three.
The Jaguar XF doesn’t offer as much flash either, but offers a wagon variant that’s gorgeous—if you’re into that sort of thing.
The Cadillac CTS is on its way out and could be found with steep discounts.
