Edmunds' Expert Review

Overall rating

The 2018 Cadillac CT6 can best be described as a full-size luxury sedan, but it's priced like a midsize. If you like the idea of a spacious and upscale luxury sedan with a little Detroit attitude, this Cadillac fits the bill.

Under the hood, the CT6's segment-straddling identity is apparent. Turbocharged four-cylinder power is standard, and it's the same engine that's featured in the Cadillac's midsize CTS. You won't find that combination in any of its German competitors.

But there's no doubt that the CT6 reaches new heights of luxury relative to its midsize brethren. Throw in generous rear passenger accommodations, top-shelf interior trimmings and a competitive starting price, and the CT6 becomes a legitimate challenger to the traditional leaders.

2018 Cadillac CT6 models

The 2018 Cadillac CT6 is a large luxury sedan available in four main trim levels. The base CT6 is well equipped, while the Luxury trim adds high-end safety and convenience features. Next, the Premium Luxury adds even more technology, followed by the Platinum, which makes all options standard.

The base CT6 comes standard with a 2.0-liter four-cylinder turbo engine (265 hp, 295 lb-ft) and includes 18-inch wheels (19s with the V6), front and rear parking sensors, LED headlights and taillights, heated mirrors, a power tilt-and-telescoping steering wheel, an auto-dimming rearview mirror, leather upholstery, eight-way power front seats (with two-way power lumbar), driver-seat memory settings and dual-zone automatic climate control. Also standard on the technology front are GM's OnStar system (with 4G LTE connectivity and Wi-Fi hotspot capability), Bluetooth, a 10.2-inch touchscreen with Cadillac's CUE interface, Apple CarPlay and Android Auto smartphone integration, a rearview camera, voice controls, four USB charge ports, wireless charging and an eight-speaker Bose sound system with satellite radio and three audio USB ports.

An optional Driver Awareness and Convenience package adds a panoramic sunroof, automatic high-beam headlights, automatic wipers, power-folding mirrors, heated front seats, a navigation system and an array of extra safety features (see Safety section for details). There's also an optional V6 engine rated at 335 hp and 284 lb-ft.

The Luxury trim starts with all of the above equipment and adds another engine choice, a 3.0-liter twin-turbo V6 (404 hp, 400 lb-ft), automatic parking system, auto brake hold (prevents forward/rearward creep when your foot is off the brake), a hands-free trunklid, four-way power lumbar for the front seats, front passenger-seat memory settings, a top-down 360-degree parking camera system, rear side window shades, upgraded interior lighting and a 10-speaker Bose surround-sound audio system.

The optional Comfort package adds ventilated front seats and heated rear seats. There is also an Enhanced Vision and Comfort package with those upgraded seats plus a unique rearview mirror that displays streaming video from a special rearview camera.

Moving up to the Premium Luxury gets you an upgraded gauge cluster display, a head-up display, and the Enhanced Vision and Comfort package as standard.

For both the Luxury and Premium Luxury trim levels, an available Rear Seat package bolsters the CT6 Luxury's feature list with a rear entertainment system and four-zone automatic climate control. An available Active Chassis package (not available with the 2.0-liter engine) bundles adaptive suspension dampers, active rear steering and 20-inch wheels. A 34-speaker (yes, 34) Bose Panaray premium audio system is also optional. For the Premium Luxury trim only, an optional Driver Assist package adds adaptive cruise control, a night vision camera system and enhanced safety-related automatic braking.

At the top of the totem pole is the Platinum, which adds all of the above as standard equipment plus 12-way power-adjustable front seats with massage functions, premium leather upholstery, and eight-way power-adjustable outboard rear seats with ventilation.

The Plug-In variant takes many of the options available in the Premium Luxury and Luxury configuration and makes them standard, along with a new 2.0-liter turbocharged hybrid powertrain (335 hp, 432 lb-ft). The Driver Awareness and Convenience and the Enhanced Vision and Comfort packages are all standard. The Hybrid comes with 18-inch wheels and is only available in rear-wheel drive. Due to the large battery pack, you do lose significant trunk volume.

Trim tested

The ratings in this review are based on our Full Test of the 2016 Cadillac CT6 Platinum (twin-turbo 3.0L V6 | 8-speed automatic | AWD).

NOTE: Since this test was conducted, the current 2018 Cadillac CT6 has received some revisions, including a new nine-speed automatic transmission for 2017 and the deletion of the Premier trim level. Our findings remain broadly applicable to this year's 2018 Cadillac CT6.


Formidable acceleration, powerful brakes and a smart transmission give the CT6 a king-of-the-road character that befits its flagship status.


The turbocharged V6 has strong pull from almost any rpm, and quick, smooth upshifts give the sense of virtually uninterrupted power. Zero to 60 mph takes 5.2 seconds, though, which puts this top-of-the-line CT6 midpack among top-shelf sedans.


The CT6's brake pedal is reassuringly firm and easy to modulate. Despite the car's roughly 4,400-pound bulk, the brakes hauled it down from 60 mph in just 102.4 feet in Edmunds testing, a stunning performance for a luxury sedan.


The steering effort gets artificially heavy in Sport mode without adding any tangible value for spirited driving. Left in its default mode, it's light and pleasantly accurate, if typically numb for the segment.


Body roll is held within reasonable bounds, but the CT6 feels large and long. Some cars shrink around you at speed; this isn't one of them. The CTS on which it's based is a great athlete, but the CT6 is unremarkable, like a stretched CTS on novocaine.


Throttle modulation is intuitive, but the transmission sometimes feels as if it has only two modes: "stay in current gear" or "redline ho!" An in-between step would be appropriate for a dignified luxury car.


The CT6 has potential in this category, but our test car's jittery ride held it back. Put the ride aside, and you've got a roomy, well-appointed sedan with a quiet cabin and massaging seats front and rear.

Seat comfort

The wide front seats don't offer much lateral support but are plenty comfortable on long hauls. Massage controls are finicky, but the multiple massage programs are addicting. The rear outboard seats feel first-class and offer massage functions of their own.

Ride comfort

Even on roads we know to be fairly smooth, our CT6 Platinum quivered uncomfortably. The ride was also a bit flinty over impacts, so we never really felt as if it was dialed in the way a car in this class should be.

Noise & vibration

The CT6's 3.0-liter V6 sends vibrations through the steering wheel at 4,500 rpm, which is common for a V6 but unwelcome at this price (e.g., Audi's V6 doesn't do it). The highway ride is hushed, with little wind, road or tire noise to speak of.

Climate control

Strong A/C performance and quiet fan. User-friendly touchscreen interface for climate controls with redundant controls below. Separate controls for rear passengers look like the redundant ones in front. Effective seat heating and cooling front and rear.


High-end materials are just about everywhere you look and touch, and the Platinum model we tested has every available feature. A good showing for the price, although customization options are limited.

Ease of use

Cadillac's infotainment interface has been improved since its introduction. The 10.2-inch touchscreen features large, easy-to-understand icons and a sensible menu structure. Other controls are mostly user-friendly as well, so it's an easy car to live with.

Getting in/getting out

Large doors afford wide openings all around, and the CT6's seats are at the perfect height to slide right in. Convenient and welcoming for all ages and stages.

Driving position

The CT6's power-adjustable wheel doesn't telescope out far enough, so it'll be a reach if you need to slide the seatback a ways. The wheel itself feels substantial in your hands, and gauge visibility is excellent. Up and down range for the seat is ample.


Tons of rearward travel for the front seats, and generous room in all other directions. Taller drivers have plenty of space. Rear-seat room is also ample, even for larger folks, but there are no footrests as in some competitors.


The view out is satisfactory front and rear. You don't feel as if you're peering out of a bunker. The streaming-video rearview mirror had us seeing double due to the different focal point, but it shows a wider view of what's behind (and can be turned off).


The CT6 Platinum's cabin is swathed in leather and chrome interior trim is thankfully sparse. Overall, the effect isn't quite as nice as what you get from Audi or Mercedes-Benz, but it's getting harder to pinpoint the flaws.


At heart, the CT6 is a stretched version of a midsize sedan (the CTS), and that shows in its relatively short and small trunk. Cadillac could also do a better job at providing interior storage options; the stylishness of the dashboard and center stack seem to have taken priority.

Small-item storage

The touchpad on the center console takes up some space that might otherwise be used for phone storage. You'll manage in the CT6, but your phone might end up in one of the cupholders. Decent room for other stuff under the center armrest.

Cargo space

The trunk has a wide opening that's great for loading large items such as golf bags. The trunk narrows abruptly at the rear wheelwells, however, and overall volume is modest at 15.3 cubic feet.

Child safety seat accommodation

The CT6's long rear doors and large back seat give it an inherent advantage compared to smaller sedans. A rear-facing child seat should fit with no need to adjust the position of the corresponding front seat. The two sets of LATCH anchors are easy to access.


Technology is a strong suit for the CT6, especially now that the user interface has been revised with a beautiful 10.2-inch display and quicker response times. If you're looking for high-tech features that are also user-friendly, the CT6 is a good pick.

Audio & navigation

Cadillac's CUE system has been improved. The touchscreen looks great and responds promptly to commands. The redundant touchpad between the seats provides odd haptic vibration feedback. Bose Panaray system sounds rich and full.

Smartphone integration

Apple CarPlay and Android Auto come standard on the CT6. Cadillac's got you covered with four USB charge ports, three USB audio ports and wireless charging to boot. Bluetooth phone pairing is quick and painless.

Driver aids

The CT6 Platinum comes standard with adaptive cruise control, forward collision mitigation, lane departure intervention, blind-spot monitoring, rear cross-traffic alert and a night vision system. There's also a streaming-video rearview mirror.

Voice control

Our repeated attempts to change iPhone playlists were unsuccessful even though we used the proper voice command structure ("Play playlist [name]"). Instead, a sustained press of the voice button accesses the iPhone's Siri voice commands, which work quite well.

Fantastic voyage
PLUG-IN 4dr Sedan (2.0L 4cyl Turbo gas/electric hybrid EVT)
I absolutely love this car. I have owned 6 cars and 3 SUV's and the CT6 hybrid is by far the best. The ride is incredible. The ride is so smooth it feels as though you are floating. The seats hug you as you drive and it feels as though they were made just to fit your body. The technology in this car is amazing and surprisingly easy to navigate.
Best vehicle in town.

Get it in writing the price you're willing to purchase, because if it's too, good to true, then it probabily is.
Cadillac that delivers seamless torque/ride qualit
PLUG-IN 4dr Sedan (2.0L 4cyl Turbo gas/electric hybrid EVT)
The 2018 Cadillac CT6 plug-in with 40 miles of battery range and full tank of gas will exceed +500 miles or more than any current EV car. On battery 80-100 mpge is the norm and on longer drives 35 mpg at highway speeds and 40 mpg when the 2.0T engine is fired up in the city. The battery will get me to work to charge there and home with errands and eating out with ease as we have seen over 1,500 miles without gasoline engine firing up. The CT6 wheel base is long so most road irregularities are taken with ease. Though rougher surface steets do transmit through the ridge aluminum and steel chassis. The seat area is comfortable and wide with good thigh support for longer legs. The heated and vented seats can be programmed for everytine the car is started. Though tech features like rear view camera is mostly used in congested setting with limited distance viewing like a regular rear view mirror, the night vision works wonders in highlighting sidewalk walkers while deer silhouettes are highlighted with a flashing display and vibrating seat given plenty of time to slow. The night vision works wonders in thr fog that the human eye cannot see. This 2018 was purchased new in March 2020 for about half off the listed price as nothing could match it technology for the middle $30's price.


Our experts like the CT6 models:

Following Distance Indicator

Should I lease or buy a 2018 Cadillac CT6?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
