2017 Cadillac CT6 review: Our expert's take

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.

The Perfect Luxury car

I purchased the CT6 Luxury AWD new in 2017. I haven't had any issues at all. I love the double sunroof and the 360 camera view. But what I am really upset about is GM discontinued this model. It is an awesome driving car and I won't be getting rid of it anytime soon.


Looks Can be Deceiving

There's a class action suit against GM for installing faulty transmissions in Cadillac Escalades. On my CT6 I had front end issues and it took months to find the parts. My sunroof is broken. Cadillac wants $3,200.00 to fix it. This is a 6 year old car with 69k, and should not have sunroof issues. GM is making such inferior products and all charging top dollar. I've been a Cadillac guy for 20 years, and unfortunately this will be my last.


Fix the Brake Squeaks

The brakes squeak constantly after allegedly being fixed. It is embarrassing to drive, slightly tap your brakes and the world hears your brakes. I want action.
