TCC’s Bottom Line

The 2015 Audi A6 may look a little sedate, but it's a brilliant performer–thanks to its diesel-driven TDI, the supercharged A6, or turbocharged S6 versions. If you're looking for a car that offers comfort, technology, and safety as its greatest virtues, the 2015 Cadillac XTS does everything a big luxury sedan should. The 2015 Mercedes-Benz E-Class lineup is many vehicles in one, with comfort and luxury across the board and sporty manners for those who want them.
