The Audi A6 competes in a crowded segment, filled with excellent alternatives.
The Mercedes-Benz E-Class looks great, rides well, offers a diesel option, and its E63 AMG is insanely fast.
The BMW 5-Series comes with a similar number of configurations, but feels more like a sports sedan than the Audi.
The Infiniti Q70 is also offered in a long-wheelbase version this year, and comes with excellent handling and enough tech features to rival the Audi.
The Chrysler 300 is an all-American alternative, with better handling than the A6, and a smoking SRT performance variant.
Finally, there's the Cadillac CTS, with excellent driving dynamics, razor-sharp styling, and plenty of feature and safety tech.
