The XTS is quite luxurious, with a very spacious and well-appointed cabin and a roomy trunk. Based on the previous generation of GM's large sedan platform, it shows its limitations in terms of ride comfort and handling agility.
The XTS is powered by a 3.6-liter V6 engine that's mated to a six-speed automatic transmission. And while this combination isn't the most refined or advanced you'd 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 is also available but only with all-wheel-drive.
