Is the Cadillac CT6 a Good Car?

Despite its low ranking, the 2019 CT6 is a good car. It has a lineup of solid engines and offers a composed, comfortable ride. The second row comfortably seats even tall passengers, and there's a long list of standard and optional entertainment and advanced safety features. Compared to some other luxury large cars, however, the CT6's flaws are more evident. Interior quality isn't up to snuff, especially for what you might expect from a brand's flagship sedan. Also, class rivals are more fun to drive, and some offer more cargo space.

It’s worth noting that partway through the year, Cadillac made major changes to the CT6. We detail them in the section below.

Should I Buy the Cadillac CT6?

The base 2019 CT6 Luxury trim retails for $50,495 which is about $3,500 less than the previous model’s base price. That's on the low end of prices in this class, so it's clear that Cadillac is positioning the CT6 as a value-laden alternative to cars that cost tens of thousands of dollars more. The base CT6 comes with amenities like leather upholstery and a 10.2-inch touch-screen with a built-in Wi-Fi hot spot, Android Auto, and Apple CarPlay. But that's not enough to make the CT6 a slam-dunk purchase.

Partway through 2019, Cadillac discontinued the base Luxury trim, as well as the four-cylinder engine and rear-wheel drive. The Premium Luxury is now the base trim, and it comes with a 3.6-liter V6 engine. Note that you might still find some Premium Luxury trims with the four-cylinder engine on dealer’s lots. Additionally, Cadillac launched the high-performance CT6-V trim for this model year. It features a twin-turbo V8 engine, though you’ll have to check with Cadillac for availability.

You may also want to consider a widely acclaimed luxury midsize car like the BMW 5 Series, which offers dynamic performance, a classy cabin, and a ton of space. The Cadillac XTS is priced similarly to the CT6, but it doesn't offer many advantages compared to its stablemate.

Should I Buy a New or Used Cadillac CT6?

The CT6 launched as a brand-new model for the 2016 model year. A plug-in hybrid CT6 debuted for 2017. For 2018, Cadillac introduced its Super Cruise technology, which is a Level 2 semiautonomous driving system.

For 2019, the CT6 received an exterior design refresh and went through a few powertrain changes. When the 2019 CT6 debuted, it featured a new standard powertrain. The engine was still a turbocharged four-cylinder like you'd find in the 2018 CT6, but horsepower was down to 237 from 265. It was paired with a new 10-speed automatic transmission that replaced the eight-speed automatic. Aside from improved fuel economy, there weren't any notable performance advantages to this new pairing.

As mentioned above, Cadillac altered the CT6's trim lineup later in the model year. Depending on dealer availability, you may still find some models that feature the turbocharged four-cylinder base engine, but later models feature a V6, twin-turbo V6, or twin-turbo V8, as Cadillac streamlined its trim offerings.

If you’re interested in the semiautonomous system, stick with a 2018-or-newer CT6. Otherwise, consider saving some money by going with an otherwise similar 2017 or 2016 model instead.

Cadillac CT6 Versus the Competition

Which Is Better: Cadillac CT6 or BMW 5 Series?

The BMW 5 Series is a luxury midsize car, but it compares favorably to the CT6. It has a more luxurious interior than the Cadillac's underwhelming cabin, and while both luxury sedans have a spacious back seat, the 5 Series serves up several more cubic feet of trunk space. The BMW has the edge in overall performance too, as its engines deliver plenty of power, and its handling is a perfect blend of athleticism and comfort. The choice is clear: Go with the 5 Series.

Which Is Better: Cadillac CT6 or Cadillac XTS?

The Cadillac XTS is the brand's other luxury large car, and like the CT6, it's mired in the bottom of the class rankings. The XTS has so-so handling and mediocre engine power, and its ride quality can’t match the comfort of the CT6. Inside, both Cadillacs suffer from some drawbacks with their infotainment systems. Both have good but not great cabin design and materials. While neither is short on rear-seat space, the CT6's rear seats are more accommodating. You will get more cargo room with the XTS. The main reason to consider the XTS might be price. With a starting MSRP of just under $47,000, it’s considerably less expensive than the CT6.

CT6 Interior

How Many People Does the CT6 Seat?

The Cadillac CT6 sedan seats five people. Its standard accommodations include leather upholstery and 14-way power-adjustable front seats. You can opt for various combinations of 16- or 20-way power-adjustable, heated, ventilated, or massaging front seats. The front buckets are soft and supple, providing excellent comfort for long drives. However, they're a little wide and flat, with subpar side bolstering and lateral support. The cabin feels open and airy in the front.

This big Caddy is also notable for its cavernous second row. Even taller riders should be able to comfortably stretch their legs. The range-topping CT6 Platinum trim ups the ante with heated, ventilated, massaging, and reclining rear seats.

CT6 and Car Seats

The CT6 has two complete sets of LATCH car-seat connectors in its rear outboard seats and a dedicated tether anchor for the middle seat. The lower anchors are set a little deep in the seat, but it's easy to move the cushion away to access the connection points. The expansive second row also lets you fit and install car seats of most sizes with little issue.  

CT6 Interior Quality

Interior quality is a bit of a mixed bag in the CT6. It has the requisite leathers and soft-touch surfaces for a car in this class, but the whole package falls short of rivals that are more luxurious overall. Some trim pieces feel flimsy, and other knobs and handles are similar to those found in less expensive cars made by General Motors.

CT6 Cargo Space

The CT6's trunk measures 15.8 cubic feet, which is about average compared to other sedans in the luxury large car class. The Cadillac XTS is on the upper end of the spectrum at 18 cubic feet, and the luxury midsize BMW 5 Series boasts 18.7 cubic feet.

This Cadillac offers practical cargo space, with a large and wide trunk opening and a low trunk floor. You can easily load in heavy cargo, but the trunk narrows toward the back. A hands-free trunk is optional, allowing you to wave your foot under the bumper to pop the lid.

CT6 Infotainment, Bluetooth, and Navigation

The 2019 CT6 comes standard with the Cadillac User Experience infotainment system and a 10.2-inch touch screen. The system's large buttons and quick processing times make it fairly straightforward and intuitive to use, but there are some hiccups. Menus can be difficult to navigate. A rotary knob on the center console offers another way to control most of the car's features.  

Additional standard amenities include an 8-inch digital instrument display, an eight-speaker Bose premium sound system, satellite radio, wireless device charging, a built-in Wi-Fi hot spot, and smartphone integration through Android Auto and Apple CarPlay. Options include four-zone automatic climate control, a sunroof, navigation, a 10- or 34-speaker Bose surround-sound stereo, a 12-inch digital instrument display, and a rear-seat entertainment system. When the Premium Luxury trim became the new base model partway through the year, some of these options – such as the sunroof and the 10-speaker Bose stereo – became standard.

CT6 Performance

CT6 Engine: Three's a Crowd

For CT6 base models produced in the first half of the model year, the standard engine is a 2.0-liter turbocharged four-cylinder that puts out 237 horsepower and 258 pound-feet of torque. Acceleration is decent, especially given the car's large size, and there's little noticeable turbo lag.

Midway through the model year, the base turbo-four engine was eliminated, making a 3.6-liter naturally aspirated V6 engine standard. It makes 335 horsepower and 284 pound-feet of torque. A 3.0-liter twin-turbo engine that boasts 404 horsepower and 400 pound-feet of torque is available. New for 2019 is a 10-speed automatic transmission that’s standard throughout the lineup. It performs inconspicuously most of the time, though it can sometimes lurch through gears or upshift too early.

Partway through 2019 Cadillac also introduced a high-performance version of the CT6, dubbed the CT6-V. It features a 550-horsepower twin-turbocharged V8 engine. Along with all-wheel drive, the CT6-V boasts performance upgrades like Brembo brakes and a limited-slip rear differential. Check with your dealer for availability.

CT6 Gas Mileage: A Mixed Bag

Models with the four-cylinder engine are highly efficient, earning up to 24 mpg in the city and 34 mpg on the highway, which are among the best numbers in the class. The two V6 engines fare worse. The naturally aspirated V6 returns 18 mpg in the city and 27 mpg on the highway, while the twin-turbo V6 earns 18/26 mpg city/highway. Notably, the four-cylinder engine was discontinued partway through the year.

The BMW 5 Series matches the CT6's best estimates, and the Cadillac XTS manages up to 19/28 mpg city/highway.

CT6 Ride and Handling: Not That Special

The Cadillac CT6's road manners are more polished than playful. This big sedan dispatches most bumps in the road, and the cabin stays insulated from most outside noise, even at high speeds. Steering feels somewhat numb and disconnected, though, and there's little feedback from the road. However, at low speeds, steering effort is light, so it's easy to maneuver the CT6 through tight spaces.

CT6 Safety

CT6 Crash Test Results

The 2019 Cadillac CT6 has not been put through crash testing by either the National Highway Traffic Safety Administration or the Insurance Institute for Highway Safety. That's common for luxury vehicles.  

CT6 Safety Features

The CT6 comes standard with a rearview camera and front and rear parking sensors, which are ubiquitous throughout the industry and unimpressive for a high-end luxury sedan. The Teen Driver feature is also standard, letting you put limits on things like speed and audio volume for secondary drivers.

The most notable available advanced safety feature in the CT6 is Cadillac's Super Cruise technology. This Level 2 semi-autonomous driving system works on about 130,000 miles of limited-access highways that Cadillac has mapped across the country. The car stays in your chosen lane and can accelerate, brake, and maintain the speed of traffic. Level 2 automation means that some automated systems have been combined, but the driver must remain alert while driving and be prepared to take over full operation at any time.

Partway into 2019, some of these features, including automatic parking assist, forward collision warning, lane keep assist, lane departure warning, lane change alert, blind spot monitoring, rear cross traffic alert, the safety alert seat, the following distance indicator, and the 360-degree parking camera, became standard.

Which Cadillac CT6 Model Is Right for Me?

The 2019 Cadillac CT6 comes in four trim levels: Luxury, Premium Luxury, Sport, and Platinum. Luxury and Premium luxury models come standard with a 2.0-liter turbocharged four-cylinder engine and rear-wheel drive, while a 3.6-liter V6 engine with all-wheel drive is optional. Sport and Platinum models feature a 3.0-liter twin-turbocharged V6 engine with all-wheel drive. All models have a 10-speed automatic transmission. A high-performance CT6-V with a twin-turbo V8 engine joins the lineup later in 2019.

The base model is a good value, with a long list of amenities and a relatively low starting price for a luxury large car. It also gives you the option of adding several active safety features in one package. However, Cadillac cut the Luxury trim and the four-cylinder engine partway through the model year. For many shoppers, the new base setup will be the Premium Luxury trim and its 3.6-liter V6 engine.

Cadillac CT6 Luxury

The 2019 Cadillac CT6 Luxury starts at $50,495 and comes standard with a four-cylinder engine. With the optional 3.6-liter V6 and all-wheel drive, prices start at $55,495. Standard features include leather upholstery, 14-way power-adjustable front seats, a leather-wrapped steering wheel, dual-zone automatic climate control, rain-sensing windshield wipers, proximity keyless entry, push-button start, remote start, and an 8-inch digital instrument display. Standard driver assistance features include a rearview camera, front and rear parking sensors, and the Teen Driver system. The standard infotainment system features a 10.2-inch touch screen, Bluetooth, two USB ports, an eight-speaker Bose premium sound system, satellite radio, wireless device charging, a built-in Wi-Fi hot spot, Android Auto, and Apple CarPlay.

Most major options for the base Luxury trim are found in the Driver Awareness and Convenience package. For $3,500, you can get active safety features like automatic high beams, a safety alert seat, a following distance indicator, lane departure warning, lane keep assist, blind spot monitoring, rear cross traffic alert, forward collision warning, pedestrian detection, and low-speed automatic emergency braking. It also comes with heated front seats, a sunroof, and navigation.  

Notably, this trim was cut partway into 2019, so many shoppers will be unable to find one. Most of its features carry over to the new base Premium Luxury model.

Cadillac CT6 Premium Luxury

The CT6 Premium Luxury starts at $58,095 with the standard powertrain and $62,595 with the midrange V6 and AWD. Additional features in this trim include a 10-speaker Bose surround-sound stereo, 16-way power-adjustable and heated front seats, a heated steering wheel, a hands-free power trunk, automatic parking assist, and a surround-view parking camera. The Premium Luxury model also comes with all the features in the base trim's optional package.

For $2,000, the Comfort and Technology package comes with ventilated front seats, heated rear seats, a head-up display, a rearview mirror camera, and a 12-inch digital instrument display. The Rear Seat package ($2,700) includes four-zone automatic climate control and a second-row entertainment system.

In models with the V6 engine, you can spend $6,000 to get a package with Cadillac's Super Cruise driver assistance technology, along with adaptive cruise control, night vision detection, and reverse automatic braking. This package also includes magnetic ride control, active rear steering, and a choice of upgraded wheels. You can also get just the magnetic ride control and rear-wheel steering for either $2,600 or $3,300, depending on your choice of wheels.

Partway through the year, Cadillac made the Premium Luxury the new base trim. It generally has the same features but comes standard with the 3.6-liter V6 and all-wheel drive. These updates raise its retail price to $62,595.

Cadillac CT6 Sport

The 2019 CT6 Sport retails for $66,595. It features a twin-turbo V6 engine and standard all-wheel drive, along with a unique, sporty interior and exterior design elements. The CT6 Sport has mostly the same list of standard and optional features as the Premium Luxury trim.

Cadillac CT6 Platinum

The Cadillac CT6 Platinum trim starts at $86,795 and comes fully loaded with most of the features you can get in the car. It includes 20-way power-adjustable, ventilated, and massaging front seats; heated, ventilated, massaging, and reclining rear seats; four-zone climate control; a rear-seat entertainment system; a head-up display; a rearview mirror camera; a 34-speaker Bose stereo; the Super Cruise function and its associated advanced safety features; magnetic ride control; and rear-wheel steering.

Cadillac CT6-V

The all-new 2019 Cadillac CT6-V is a high-performance, limited-production model of the sedan. It boasts a twin-turbocharged V8 engine, all-wheel drive, Brembo brakes, and a limited-slip rear differential. Prices start at $87,795. Check with Cadillac for availability.

The Final Call

The 2019 Cadillac CT6 is a well-rounded luxury large car, but it doesn't do enough to stand out from the crowd. It delivers solid overall performance thanks to its energetic engines and composed handling, and the cabin is spacious and quiet. However, some rivals offer a nicer interior, more trunk space, or more straightforward infotainment features. Many of them have higher predicted reliability ratings too.

Don’t just take our word for it. Check out comments from some of the reviews that drive our rankings and analysis.

  • "The CT6 offers great value and finally looks like a proper premium sedan." -- CNET
  • Aside from high feature content, the CT6 is priced competitively to established large luxury sedans. And it is generally simpler to shop for thanks to its uncomplicated trim and options structure. Unfortunately, that simplicity also means you don't get the customizability or truly exclusive options that the high-end luxury sedan segment is all about. … Ultimately, if style, value and technology are your priorities, the Cadillac CT6 should be a prime consideration." -- Edmunds
  • The Cadillac CT6 has all the virtues you expect out of a big, luxurious sedan: comfortable, quiet, and spacious. However, when you put the sum of its parts together, it feels generic. … With the exception of Super Cruise and the CT6's angular exterior design, it's hard to distinguish the Cadillac from its competitive set." -- Motor Trend
