Cadillac CT6

The CT6, produced from 2016 through 2020, was a return to form for Cadillac in the full-size luxury sedan segment, which had long been dominated by European rivals. The big Caddy has endeared owners with its bold styling, roomy interior, and welcome balance of comfort and performance, especially when equipped with one of the available turbo V6 and V8 engines. The CT6 was also the first model to offer Cadillac’s highly praised hands-free driving system, Super Cruise. On the downside, some find the CT6 lacking the same levels of polish found in luxury flagships from class leaders such as BMW and Mercedes-Benz.

Cadillac CT6 Model Lineup

The CT6 is a full-size luxury sedan with room for up to five passengers. Until being discontinued in 2020, it was Cadillac’s largest sedan, measuring about a foot longer than the next smaller model, the midsize CT5 (on which the CT6 is based).

Cadillac sold the CT6 in a variety of trims and powertrains. Entry-level trims, including the base and the Luxury, feature a standard 2.0-liter turbocharged four-cylinder engine driving the rear wheels (only), while pricier trims, including the mid-tier Premium Luxury and the high-end Platinum, are upgraded to a 3.6-liter V6 and all-wheel drive. An optional 3.0-liter turbo V6 was also available for the upper trims, bumping output from 335 to 404 horsepower; it was fitted as standard equipment on the one-year-only Sport trim, which appeared in 2019. That same year, Cadillac first offered a 4.2-liter turbo V8 as an option on the Platinum and as standard equipment on the high-performance CT6-V, where it makes a whopping 550 hp. Finally, a plug-in hybrid variant delivering 62 MPGe and up to 31 miles of all-electric range was offered from 2017 through 2018.

As Cadillac’s flagship sedan, the CT6 came well equipped with features regardless of trim. The standard equipment list boasts LED headlights, front and rear parking sensors, leather upholstery, dual-zone climate control, and a 10.2-inch infotainment touchscreen with Apple CarPlay and Android Auto integration, a WiFi hotspot, and a wireless smartphone charger. In 2020, Cadillac added a host of other desirable standard features (which were previously optional), including heated front seats, navigation, forward collision mitigation, blind-spot warning, and lane-keeping assist. Adaptive cruise control was an option throughout the CT6’s production run, and Cadillac’s excellent semi-autonomous driving system, Super Cruise, first became available in 2018.

I would not recommend this vehicle and have told friends and co workers to stay away. Biggest issue is the problem with vehicle experiencing what feels like a surge of power from the engine or almost being struck from behind when you stop the vehicle in traffic. Told the maintenance staff twice about it, they said it needed a software upgrade. Got the upgrade, no change. You never know when it will happen, but the sensation of the engine revving or being hit from behind when you are in traffic is unnerving because you NEVER KNOW when its coming. Hate that you can't turn 'off' the engine shut off at stops in traffic to save fuel for the vehicle. I'm sure this is how Cadillac shows they are energy efficient, but this is a pain in the ass. Every time I drive I have to push the button to turn off that feature or I deal with the delay in power at the light. Unless the above mentioned 'feature' occurs with my car.

The styling and luxury options on the CT6 are great. The car is quite huge though - bigger than I thought at 204+ inches long (as big as some trucks). That said I like a big ride but be sure parking it in some parking lot spaces will be sometimes a challenge - it also fits in my 2 car garage but sometimes a tight fit. I believe Cadillac can figure a way to shorten the wheelbase without sacrificing front/Back Seat room and trunk space. The engineers can figure out a way to reduce the car by 4-6 inches -- maybe off the front end which is pretty lengthy. Overall the car is sweet though - haven't had any major issues to date

Would never buy a CT6 again. Transmission is terrible for a $70K vehicle
