IT’S A BEST BUY BECAUSE:

The CT6 is an underrated large luxury sedan that offers impressive style, performance, and available safety and technology features, all at prices that undercut most class competitors.

BUT…

The CT6 is probably going to be discontinued for 2021, and its ride quality and interior luxury don’t quite meet the level of European rivals.

WORTH NOTING:

The CT6 offers Cadillac’s Super Cruise semi-autonomous driving system, which enables hands-free driving on select limited-access highways when certain conditions are met.

WHAT IS IT?

The CT6 is a 4-door large luxury sedan that debuted for 2016 as the flagship of Cadillac’s passenger-car lineup. After previously offering up to five powertrain choices, including a plug-in-hybrid model, the engine lineup has been pared down to three for 2020: a 335-hp 3.6-liter V6 (offered in Luxury and Premium Luxury models), a 500-hp twin-turbo 4.2-liter V8 (Platinum model), and a 550-hp version of the twin-turbo 4.2 (high-performance CT6-V model). All engines are paired with a 10-speed automatic transmission and all-wheel drive. Available safety features include adaptive cruise control, blind-spot monitor with rear cross-traffic alert, teen driver monitoring system, forward and reverse collision warning with automatic emergency braking, rearview camera mirror, night-vision camera system, and 360-degree surround-view camera display with recording capability. Other available features include Magnetic Ride Control, Active Rear Steer, rear-seat entertainment system, heated/ventilated front seats, heated rear seats, and a 34-speaker Bose Panaray audio system.

WHAT’S NEW?

In addition to its pared-down roster of available engines, the CT6 gets a few previously optional features as standard equipment. The 2020 model year will likely be the CT6’s last.

FUEL ECONOMY

The 3.6-liter V6 is EPA-rated at 18 mpg city/27 highway, and the Platinum version of the turbo 4.2-liter V8 is rated at 14/25. Fuel economy estimates for the CT6-V’s version of the 4.2 were unavailable as of this writing.

VALUE IN CLASS

The Cadillac CT6 is an unconventional choice for Best Buy status, as it never quite found a foothold in the marketplace. That’s more a reflection on changing buyer preferences than the CT6 itself. This is a surprisingly athletic large sedan that offers distinctive looks inside and out, the choice of refined V6 or ferocious V8 power, and a fine selection of available high-tech features (including Cadillac’s excellent Super Cruise system, which sadly isn’t offered on the CT6-V model).
