The Mercedes-Benz E-Class and BMW 5-Series are both natural competitors to the Audi A6 and frequently cross-shopped.
The 5-Series has better performance in base models, but its dizzying array of options can be difficult to digest.
The E-Class has more advanced powertrain options than the A6, and a new wagon version of the Mercedes mid-sizer could tempt some SUV buyers.
The Cadillac CTS can be less expensive, but its powertrain doesn't feel as smooth or refined.
The new Jaguar XF is a relaxed cruiser with excellent handling and diesel power available, though its cabin isn't as charming as the Audi's.
