The Car Connection's Take
TCC Rating

8.4
TCC’s Bottom Line
Brilliance takes many forms in the Audi A6: the diesel-driven TDI, the supercharged A6, or the turbocharged S6 all stand out in ways the sedate body doesn't quite match. For those focused on safety, technology, and comfort—but not necessarily performance—the 2014 Cadillac XTS is everything a big luxury sedan should be. What, me worry? The Mercedes-Benz E-Class reasserts its alpha status with a tighter forehead, a greener turbodiesel, and a pair of all-wheel-drive AMGs.
