Cadillac's flagship large sedan possesses some athletic chops and is lively to drive. While the ride is firm, the CT6 is steady and controlled, and the interior is very quiet. The base engine is a turbo-four, but most buyers will opt for the midlevel nonturbo V6; the top trim carries a 404-hp, twin-turbocharged V6. All-wheel drive is standard on versions with V6 engines. The interior is plush and roomy, but in-cabin storage is practically nonexistent. Front-seat comfort is superb, but the rear seat is a bit short on thigh support. Despite updates, the Cue infotainment system remains unintuitive and highly distracting to use. A plug-in hybrid version with an estimated 30 miles of EV range is also available. The CT6 offers GM's Super Cruise driver-assistance system, which operates on freeways and monitors the driver to make sure he or she is paying attention.
