This sedan is wonderfully luxurious, with a spacious, well-appointed cabin and a roomy trunk. But the car lacks the silky ride you'd expect from a big Caddy, and though it handles well for its size, it doesn't have the finesse or brawn of the better German and Asian competitors.
A 3.6-liter V6 engine mated to a six-speed automatic transmission comprises the powertrain. And while this combination isn't the most refined or advanced you'll find, it ultimately performs well and achieves a respectable 22 mpg overall on premium fuel. All-wheel drive is optional on all but the base trim level. A potent and super-responsive 410-hp, twin-turbo 3.6-liter V6 was added as an option for 2014, but it was only offered with all-wheel-drive.
The XTS is also hampered by a high-tech infotainment system called CUE (for Cadillac User Experience). The system is so convoluted and frustrating that it detracts from the XTS's pampering environment. Overall, the XTS's road-test score places it just mid-pack of this competitive class.
Best version\/options to get
We suggest getting the Luxury trim version, which offers the handy driver's assistance package and navigation system. It also has most of the bells and whistles you'll find in higher trims, but costs much less and skips the complex reconfigurable gauge cluster.
