The restyled first-generation Cadillac XTS is a full-size luxury sedan built around comfort, quiet running and generous rear-seat space, with a choice of naturally aspirated and turbocharged V6 power depending on the version.
Every Cadillac XTS engine here is a 3.6-litre gasoline V6 paired with an automatic transmission, so the real difference lies in the drivetrain and tuning. The 3.6 V6 AT drives the front wheels, the 3.6 V6 AWD AT adds all-wheel drive for wet-weather traction, and the turbocharged 3.6 V6 T AWD AT delivers noticeably stronger overtaking pull.
