Edmunds Summary Review of the 2018 Cadillac CT6 Premium Luxury Sedan

Pros & Cons

  • Plenty of rear passenger space for adults
  • Engaging driving experience for a large luxury sedan
  • Priced less than many competing sedans
  • No V8 engine offered
  • Virtually no unique customizability compared to rivals
  • Lacks the cosseting ride quality offered by competitors


Which CT6 does Edmunds recommend?

Thanks to its price advantage, the CT6 Platinum, would be our choice. Its impressive standard features list, such as rear-wheel steering, night vision, massaging seats, rear-seat entertainment, and quad-zone climate control, exceed anything from its competitors at a similar price level.

Full Edmunds Review: 2018 Cadillac CT6 Sedan

What’s new

Changes to the 2018 Cadillac CT6 are primarily technology- and convenience-based. The ability to get over-the-air updates for the vehicle's software is one notable upgrade along with a revised user technology interface, which allows for easier app manipulation. Front-seat ventilation and the heated steering wheel control can be set to automatic while the rearview camera gets its own wash system. Finally, the automatic parking assist now incorporates pedal operation to further automate the parking process.

Vehicle overview

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.

Driving

7.5
Formidable acceleration, powerful brakes and a smart transmission give the CT6 a king-of-the-road character that befits its flagship status.

Comfort

7.0
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.

Interior

8.0
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.

Utility

7.5
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.

Technology

8.0
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.
