2018 Cadillac CT6 Interior Review

Note: This interior review was created when the 2018 Cadillac CT6 was new.


Interior: 8.0

The 2018 Cadillac CT6 features a richly styled interior and high-end materials, though it still lags behind some rivals in this area. The seats are spacious and supportive, but infotainment tech is a mixed bag in terms of usability and connectivity. The CT6’s trunk is smaller than most other large sedans’.

  • "Cadillac's 2018 CT6 offers a uniquely styled interior, distinct from its German and Japanese rivals, yet boasting the tasteful blend of wood, fine leather, and metallic and carbon-fiber trim expected in a car in this class." -- Kelley Blue Book
  • "Building on the strong foundation established by the current CTS, the CT6's interior takes American luxury to a new level with even richer materials, a gracefully styled dashboard and comprehensive technology integration. The CT6's overall design doesn't match the quality and construction of the world's best, but countering that is the car's lower price. We like the bold color schemes, too." -- Edmunds (2017)
  • "If styling and design sell cars, then this Cadillac should be far more successful than it is. Try to find an awkward line, or an odd proportion, or an unsightly detail on the Cadillac CT6. There isn't one. And while Cadillac's once controversial styling themes are now familiar to the eye, they remain unusual and unique to the brand." -- New York Daily News (2017)


The Cadillac CT6 seats five people, and leather upholstery and 14-way power-adjustable front seats come standard. Available features include heated and ventilated front seats, 20-way power-adjustable front seats, heated and ventilated rear seats, massaging front and rear seats, and power-adjustable rear seats.

Seating is a real strength of the CT6. Both rows of seats have plenty of space for adult passengers, and you can even sit three across the back without everyone getting claustrophobic. The front seats have plenty of thigh and back support, but they could use more side bolstering. The rear seats have more legroom than many other cars in the class. The CT6 features two full sets of LATCH connectors for installing car seats.

  • "The comfortably supportive front seats are matched by an equally accommodating rear bench that offers an 'executive' option, complete with recline and massage functions." -- Kelley Blue Book
  • "The CT6's front seats are firmly supportive and easy to get in and out of, but they don't hold you in place particularly well. Their optional heating, cooling and massage is certainly appreciated, though. The backseat serves up very generous legroom, even for 6-footers, and it's offered with heating, cooling, massage, power adjustments and a rear entertainment system that boasts two big screens and a multitude of media options. Suffice it to say that we're not used to seeing this level of rear-compartment luxury in the CT6's price class; it's a strong selling point for the right shopper." -- Edmunds (2017)
  • "Comfort levels are exceptionally good for four adults, and a fifth person will be happy enough to come along for the ride." -- New York Daily News (2017)

Interior Features

The Cadillac CT6 comes standard with Cadillac's CUE infotainment system, a 10.2-inch touch screen, an eight-speaker Bose audio system, three USB ports, smartphone integration via Apple CarPlay or Android Auto, Bluetooth, satellite radio, a 4G LTE Wi-Fi hot spot, wireless smartphone charging, a rearview camera, dual-zone automatic climate control, remote start, a proximity key, and push-button start.

Every model except the base CT6 also comes with a 110-volt outlet, a panoramic sunroof, navigation, a surround-view camera system, low-speed automatic braking, forward collision alert, pedestrian detection, a following distance indicator, lane keep assist, active park assist, lane departure warning, blind zone monitoring, rear cross traffic alert, and automatic high beams.

Other available features include a rearview mirror camera, quad-zone climate control, a 34-speaker Bose Panaray sound system, a rear-seat entertainment package, adaptive cruise control, enhanced night vision, and a noise-control system that cancels out road noise.

There are some features that come standard in the CT6 that would cost you extra in many rivals, such as Apple CarPlay, Android Auto, and a Wi-Fi hot spot. While that connectivity is nice, the CUE infotainment system does present some problems. The touch screen will occasionally miss inputs, and some users will think the menu layout is confusing.

  • "Every CT6 comes with the Cadillac User Entertainment (CUE) infotainment interface. We've been unimpressed with prior versions of this system in other Cadillacs, but this version features a bigger screen that reacts more quickly to inputs and lacks the uncouth ‘haptic feedback’ clunk of its predecessor. There's also a redundant console-mounted touchpad." -- Edmunds (2017)
  • "Deceptively minimalistic, the controls mask a complex automobile that can be programmed to myriad individual preferences. Technologically, the CT6 is the most advanced Cadillac ever built, and while the company's CUE infotainment system remains a source of occasional frustration, my biggest complaint with the CT6's larger 10.3-inch display is that the screen rapidly collects an unsightly amount of fingerprints." -- New York Daily News (2017)
  • "And then there's CUE. The haptic touchscreen and capacitive touch switches that control Caddy's sophisticated infotainment system are still far more difficult and distracting to use than they should be. And for the CT6, GM has added a touchpad interface that's as finicky and fussy as the mouse control in a Lexus, and simply overlays all that technology with a whole other level of user frustration. CUE crashed completely near the end of our test, leaving us with a blank screen in the center stack. We didn't miss it much, but we were surprised: We can't recall the last time such an elemental part of a modern automobile simply stopped working." -- Motor Trend (2017)


With 15.3 cubic feet of trunk space, the CT6 has enough room for nearly a dozen shopping bags. Though that is a fair amount of room, it is actually one of the smallest cargo holds in the class. Interior storage space is also on the small side. An available 40/20/40 split-folding rear seat can provide some extra cargo space if necessary. A hands-free power trunk lid that opens by waving your foot under the rear bumper is also available.

  • "Trunk volume measures 15.3 cubic feet, which is not exactly generous. However, the trunk floor is low enough that suitcases can be placed on their sides, helping to make maximum use of the available space." -- New York Daily News (2017)
  • "At 15.3 cubic feet, though, the CT6's trunk is undersized for the segment." -- Edmunds (2017)
