2020 Cadillac CT6 Review

The 2020 Cadillac CT6 has supple, roomy seats and an ample list of standard safety features. It places near the bottom of our luxury large car rankings, however, because of its mediocre cabin quality and finicky infotainment system.

  • Two potent available engines
  • Comfortable ride
  • Lots of standard features
  • Roomy seats
  • Some fussy infotainment controls
  • Less-refined interior than rivals’

Is the Cadillac CT6 a Good Car?

The CT6 doesn't fare well in our rankings, but it's still a decent luxury large car. Both of its available engines produce ample power, and the car boasts strong brakes. This Cadillac offers a long list of standard features and a well-insulated interior that prevents most road noise from seeping into the cabin. It also has abundant cargo space, with a wide trunk that makes it easy to load large items. However, while the CT6 provides a fairly smooth ride, its limited steering feedback makes it less enjoyable to drive than several class rivals. Also, its interior quality doesn't live up to the standards one expects from a luxury car.

Should I Buy the Cadillac CT6?

The 2020 CT6 has a lower base price than several class rivals, and it offers a wealth of standard technology as well as a comfortable ride. This makes it a tempting choice, but many competitors offer the same attributes plus more. For example, the Kia K900 and Genesis G80 both fare better than the CT6 in our rankings, and they each feature a more-user-friendly infotainment system. The K900 is comparably priced to the Cadillac's base model, while the midsize G80 costs thousands less.

Should I Buy a New or Used Cadillac CT6?

The 2020 CT6 is part of a generation that started with the 2016 model year, and there have been notable changes since then.

For 2017, Cadillac added a plug-in hybrid model to the lineup. The major change for 2018 was the introduction of the available Super Cruise semiautonomous driving system, which can control the car's speed, steering, and braking on certain sections of highways.

The 2019 model saw some significant changes. It debuted with a refreshed exterior and a standard four-cylinder engine mated to a 10-speed automatic transmission. Midyear, Cadillac discontinued the four-cylinder engine and rear-wheel drive and replaced them with a 3.6-liter V6 engine and standard all-wheel drive. Additionally, several features, including blind spot monitoring, rear cross traffic alert, navigation, and a power sunroof, were added to the standard features list. Also for 2019, Cadillac introduced the performance-oriented CT6-V model and discontinued the plug-in hybrid.

The only major change for 2020 is the addition of an available 4.2-liter V8 engine.

Unless you want the new V8 engine, look for a midyear 2019 model. It's nearly identical to a new CT6 and likely less expensive. And if you want a plug-in-hybrid CT6, used models from 2017 and 2018 are your only options.

Cadillac CT6 Versus the Competition

Which Is Better: Cadillac CT6 or Cadillac XTS?

The Cadillac XTS and CT6 are similar in many ways. Like the CT6, the XTS is a luxury large car with comfortable seats, powerful engines, and a comfortable ride. Both cars suffer from fussy infotainment controls and some subpar cabin materials compared to classmates. There are some notable differences between the two, however. The XTS has a slightly larger trunk (18 cubic feet versus 15.8) and a lower base price. You’ll pay more for the CT6, but you’ll get more standard safety features, including lane departure warning and lane keep assist. Choosing between these two Cadillacs comes down to your personal preferences.

Which Is Better: Cadillac CT6 or Lincoln Continental?

The Lincoln Continental costs less than the CT6, and it offers many of the same standard amenities, including Android Auto and Apple CarPlay smartphone integration, pedestrian detection, and lane departure warning. It also has a more user-friendly infotainment system. However, neither sedan provides the driving engagement and interior quality of higher-ranking classmates. Between these two, save some money and go with the Lincoln.

Which Is Better: Cadillac CT6 or Genesis G80?

The Genesis G80 is a luxury midsize car, though it offers spacious seating for five and nearly as much trunk space as the larger Cadillac. In addition to its lower starting price, the G80 delivers both nimble handling and a comfy ride that make it more engaging to drive than the CT6. The Genesis also has just as many standard features as the Cadillac, as well as a more responsive touch screen. Add in its nicer interior materials, and the G80 is a better pick for most shoppers.

CT6 Interior

How Many People Does the CT6 Seat?

There's seating for up to five people in the CT6. The front seats are spacious and provide comfortable seating for long trips, but they don’t offer much lateral support. The rear seats have plenty of space, even for taller folks. Visibility for the driver is good all-around.

The CT6 comes standard with leather upholstery, 14-way power-adjustable front seats, memory settings for the driver's seat, heated front seats, and a leather-wrapped steering wheel. Available comfort features include 16- or 20-way power-adjustable front seats, memory settings for the passenger seat, ventilated front seats, massaging front seats, heated rear outboard seats, and a heated steering wheel.

CT6 and Child Car Seats

There are two complete sets of LATCH connectors for the rear outboard seats and an upper tether for the middle seat.

CT6 Interior Quality

The CT6's interior is filled with high-quality materials such as genuine leather upholstery. However, some materials on the dash are more in line with what you'll find in a nonluxury vehicle, and the center console is too low-rent for this class.

CT6 Cargo Space

There's 15.8 cubic feet of trunk space in the CT6, which is about average for the luxury large car class. Its wide trunk opening makes it easy to stow larger items.

CT6 Infotainment, Bluetooth, and Navigation

The standard CUE infotainment system features a 10.2-inch touch screen, physical controls for climate and audio, and a rotary knob on the center console. Despite all those options, the system can be hard to navigate. The menu system runs multiple layers deep, and the voice controls aren't as intuitive as those found in other luxury vehicles.

Standard infotainment technology includes dual USB ports, Bluetooth, a Wi-Fi hot spot, Apple CarPlay, Android Auto, navigation, satellite radio, an eight-speaker Bose premium audio system, and wireless device charging. Available features include a 34-speaker Bose premium stereo, and a rear-seat infotainment system.

CT6 Performance

CT6 Engine: Potent V6 and V8 engines

The CT6’s base Luxury and midlevel Premium Luxury trims come with a 3.6-liter V6 engine that makes 335 horsepower. This engine has plenty of muscle to get the CT6 up to speed around town and on the highway. The high-level Platinum trim and performance-oriented CT6-V model come with the new-for-2020 4.2-liter V8 engine. The engine in the Platinum trim produces 500 horsepower, while the version in the CT6-V makes 550 horsepower. All engines are paired with a 10-speed automatic transmission that usually delivers smooth shifts but sometimes struggles to hit the right gear.

CT6 Gas Mileage: Poor

Models equipped with the standard V6 engine deliver 18 mpg in the city and 27 mpg on the highway, which are below average figures for the luxury large car class. EPA estimates for models with the optional V8 engine are unavailable at the time of writing.

CT6 Ride and Handling: Comfort Oriented

This all-wheel-drive Caddy is built for comfort. It delivers a composed ride over both smooth and uneven pavement, and its cabin is mostly devoid of road noise. The biggest issue is the steering, which feels numb and provides little feedback from the road.

The performance-tuned CT6-V model adds enhancements like Brembo brakes, a limited-slip differential, and driver selectable modes: Tour, Sport, Snow, and Track.

A Teen Driver system (which lets you set speed and audio limits for secondary drivers) and a safety alert driver's seat (which vibrates when it detects a possible collision) are also standard.

Cadillac's available Super Cruise technology is a semiautonomous driving system that on compatible highways and under certain conditions allows for hands-free driving, though you should always keep your attention focused on the road.

Other optional safety features include automatic parking assist, night vision detection, adaptive cruise control, reverse automatic emergency braking, active rear steering, a head-up display, a 360-degree parking camera system, and pedestrian detection.

The Final Call

The 2020 Cadillac CT6 is a decent pick in the luxury large car class. It offers a spacious, feature-filled cabin and a choice between a potent V6 or V8 engine. However, while the CT6’s ride quality and interior refinement are good, they lag far behind what you'll find in many of its classmates.

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

  • "The CT6 is a convincing executive sedan in many respects. Overall, the CT6 lacks the wow factor of the world's best, but it's also more affordable." -- Edmunds
  • "The Cadillac CT6 has all the virtues you expect out of a big, luxurious sedan: comfortable, quiet, and spacious. … 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 (2019)
  • "By cutting back in small but perceptible ways, the CT6 presents itself as more of a value buy." -- CNET (2018)
