2017 Cadillac CT6 Review

from the expert editorial team

GM is making a really big push for electrified vehicles in the coming years, and that includes the 2017 Cadillac CT6 Plug-In Hybrid.

What Is the 2017 Cadillac CT6?

The Cadillac CT6 is a full-size sedan that seats five. It's also Cadillac's flagship car and competes with the Mercedes-Benz S550, BMW 740i and Audi A8 sedans. The CT6's trim levels depict both their engines and feature levels: The 2.0L designates a turbocharged 2.0-liter four-cylinder that comes in Base and Luxury versions. The 3.6L designates a 3.6-liter V-6 that comes in Base, Luxury, Premium Luxury and Platinum trims. A twin-turbocharged 3.0-liter V-6 is designated 3.0L and comes in Luxury, Premium Luxury and Platinum versions. All-wheel drive is standard on all but the 2.0L models, which have rear-wheel drive. There's also a CT6 Plug-In Hybrid, which is covered separately.

What's New on the 2017 Cadillac CT6?

Aside from a new PHEV version, there are no significant changes to the 2017 Cadillac CT6.

How Does the 2017 Cadillac CT6 Compare to Other Sedans?

The price range for the 2017 Cadillac CT6 is vast, opening it up to competitors from the mid-size and full-size sedan classes. Compared with mid-size sedans, the CT6 is comfortable and offers a wide variety of features for a reasonable price. The same is true against other full-size sedans.

What Features in the 2017 Cadillac CT6 Are Most Important?

Significant standard features for the 2017 Cadillac CT6 include a 265-horsepower, turbocharged 2.0-liter four-cylinder engine. The engine is paired with an eight-speed automatic transmission and rear-wheel drive. Other highlights include heated side mirrors, leather upholstery, automatic climate control and wood interior trim. As required in all new vehicles in this model year, front airbags, antilock brakes and an electronic stability system are also included.

The CT6 offers a long list of available features, including two V-6 engine options: a 335-hp 3.6-liter and a 404-hp, twin-turbo 3.0-liter. All-wheel drive is also available on select models. You can choose from optional driver assists and safety features, such as a head-up display, a night vision system and forward collision warning with automatic braking. Exterior options include a rear spoiler, dual exhaust outlets, a hands-free power trunk lid, a power moonroof and Magnetic Ride Control adaptive suspension. Interior options include ventilated seats, heated front and rear seats, rear-seat climate controls, a heated steering wheel, a navigation system and OnStar with 4G LTE and Wi-Fi hot spot (subscription required).

Should I Buy the 2017 Cadillac CT6?

Except for the costly CT6 Platinum, the 2017 Cadillac CT6 offers contemporary styling, a quiet cabin and a powerful twin-turbo V-6 for a competitive price. If those features are must-haves for you, it's a good choice. Other aspects aren't as impressive. The suspension could be more athletic, and the base engine is a bit lethargic. Additionally, the cabin materials don't quite reach the level of quality offered by some competitors, and there's no folding rear seat for extra space.'s Editorial department is your source for automotive news and reviews.

The perfect luxury cruiser

by BlaneyBoi from Wheelersburg, Ohio on April 21, 2020

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
