2019 Cadillac CT6 Sedan

2019 Cadillac CT6 Sedan Review: Cutting Corners In A Luxury Sedan

by Gabe Beita Kiser

Three years after it was released, the CT6 still seems to be struggling to find its identity within the large luxury sedan segment. Where it once offered two engine options, it now offers four, with the new standard 237-horsepower four-cylinder sacrificing power for efficiency, while the 500-hp twin-turbo Blackwing V8 does the opposite. And while the sedan is stylish and well equipped as standard, it offers fewer opportunities to customize appearance and equipment compared to more refined rivals like the BMW 7 Series and Mercedes S-Class. A small trunk undermines a spacious interior, and the good handling dynamics are countered by subpar ride quality. While these conflicting areas of focus make the Caddy less of an all-rounder, it does have the appeal of a much lower price tag than its competition, as well as better-than-average fuel economy. Still, rumors of the CT6's demise after 2019 abound, as well as hopes of hybridized Cadillac variants to rival the growing gas-electric fandom - pivotal moments in Cadillac history, when sales figures are lower than ever for the brand.

2019 Cadillac CT6 Sedan Changes: 🚙What’s the difference vs 2018 CT6 Sedan?

The 2019 edition of the CT6 receives quite a few changes. It gets a minor facelift, with new lighting elements, and a tummy-tuck in the form of a new 2.0-liter four-cylinder engine, which supplanted the 3.6-liter V6 as the standard engine (but has since been discontinued). A more user-friendly infotainment system has been added, and the CT6-V joins the line-up as the performance-focused variant of the model, although it will be covered it its own review. The Blackwing V8 from the CT6-V is also now available on certain lower trims, albeit in a detuned state. 2019 also sees the CT6's infotainment controller refined and streamlined for easy use.

Pros and Cons

  • Multiple well-performing engines
  • Impressive autonomous driving tech
  • Many advanced driver assistance features available
  • Handles well for its size and segment
  • Appealing price tag
  • Blackwing V8 is a revelation, but with limited availability
  • Interior isn't as luxurious as it should be
  • Trunk space is barely adequate
  • 2.0-liter turbo four-cylinder lacks power

CT6 Sedan Exterior

The new, wider grille takes up most of the front fascia, although it is slimmer than in the past. Framing the grille are T-shaped LED headlights flanked by LED ribbons, emphasizing the sleeker, more aggressive style of the sedan. Daytime running lights and LED taillights round out the new look. As standard, the CT6 rides on 18-inch alloy wheels, although these are upgraded to 19-inch alloys on the upper trims.

Everything about the CT6 screams enormous luxury sedan, and that starts with its impressive dimensions. It's not overly tall, at 58 inches high, but it is 205.8 inches long with a 122.4-inch wheelbase. It is also quite wide, measuring 74 inches without mirrors. And it's weight is indicative of the gluttonous luxury of the vehicle, with the base-level Luxury weighing in at 3,708 lbs. The Platinum feels absolutely over the top at 4,426 lbs.

  • Length 205.8 in
  • Wheelbase 122.4 in
  • Height 58.0 in
  • Max Width 74.0 in
  • Front Width 63.4 in
  • Rear Width 64.0 in

Exterior Colors

Nine colors make up the palette for the CT6, with Black Raven being the standard paint. Radiant Silver is a no-cost option, while the base and mid-range models can also be had in Satin Steel Metallic, Stellar Black, Bronze Dune, Shadow Metallic, Manhattan Noir Metallic for an extra $625, or in Crystal White Tricoat or Red Horizon Tintcoat at a $1,225 premium. For the line-topping Platinum trim, color costs drop to only $600 extra for the last two options, with all other hues included in the price.

CT6 Sedan Performance

With four engines across the range - one of which was phased out during the first half of 2019 - performance indications are varied. The 2.0-liter turbocharged four-cylinder which was introduced for and then discontinued earlier in 2019, was the weakest of the lot, but what it sacrifices in quickness it makes up for in excellent fuel economy. A once-again now-standard 3.6-liter V6 is more potent at 335 hp and 284 lb-ft, giving the CT6 the power to break the 60 mph mark in around six seconds from a standstill. With this powertrain, passing on the highway is as easy as could be, but it will drink heavily from your fuel tank in town where traffic is heavier. Standard on the Sport and Platinum trims, the 3.0-liter turbo V6 breaks the 400 hp mark and launches even the 4,500-pound Platinum forward with remarkable haste, making the 0-60 mph sprint in as little as five seconds. The over-the-top twin-turbo Blackwing V8 throws out a whopping 500 hp - detuned from CT6-V state - meaning you will be thankful for the sturdy and adjustable head restraints as you risk whiplash when you put your foot down.

Engine and Transmission

Standard on the two lower trims is a 2.0-liter turbocharged four-cylinder engine that produces 237 hp and 258 lb-ft for the rear wheels, although all-wheel-drive is available. An optional 3.6-liter V6 is available to the same two trims and develops a more respectable 335 hp and 284 lb-ft. Only all-wheel-drive is standard with the stronger engine.

The Sport and Platinum trims come equipped with a 3.0-liter twin-turbo V6 engine, delivering 404 hp and 400 lb-ft to all four wheels, while the 4.2-liter twin-turbo V8 is reserved for the top-tier Platinum. This beastly machine throws out an insane 500 hp and 553 lb-ft. Every engine listed comes mated to a smooth and efficient 10-speed automatic transmission.

The 2.0-liter engine was discontinued part-way through the production year despite being new for 2019, meaning that the V6 became standard on the Luxury and Premium Luxury, although the Luxury trim was also discontinued. As for the twin-turbo V8, it was a limited edition engine and sold out quite quickly; but, Cadillac plans to bring it back for the 2020 edition of the CT6.

Handling and Driving Impressions

The large luxury Caddy earns its position within the luxury segment with impressive performance and handling, but it is held back from the frontrunners by its excessive weight and ride quality that doesn't match its status.

Steering is what you'd expect from the luxury segment, with the excessive lightness seeming to be overcompensating for the vehicle's sheer size. But it is accurate, albeit somewhat untalkative. The brakes are equally powerful, capable of stopping they hefty behemoth in as little as 102 ft from 60 mph without negatively impacting on feel or modulation.

The luxury sedan handles remarkably well given its size, however, where rivals seem to shrink around the driver as they speed up, the limousine-style CT6 never feels any smaller than it is. Also, this focus on controlling the chassis during high-speed maneuvers that this sedan has no business attempting means that it does sacrifice on ride quality.

Despite the luxury-level interior, the Cadillac is not as plush as the BMW 7 Series or Porsche Panamera, with comfort not being adequate enough to counteract some of the road imperfections that the suspension fails to manage. While the CT6 certainly has some strong points, it is not the capable all-rounder than many of its higher-quality rivals are.

CT6 Sedan Gas Mileage

For a high-priced luxury sedan, the CT6 is a fairly frugal fuel-sipper, especially with the 2.0-liter four-cylinder engine. When paired with the rear-wheel drivetrain, this engine is estimated to get 24/34/28 mpg across the city/highway/combined cycles. Swapping to all-wheel-drive reduces this to 21/29/24 mpg. Only available with all-wheel drive, the optional V6 gets 18/27/21 mpg, while the twin-turbo V6 gets 18/26/21 mpg. Segment rivals like the BMW 7 Series and Audi A8 get 21/29/24 mpg and 19/27/22 mpg, respectively, putting the Cadillac in the lead in terms of fuel economy. With a 19.5-gallon tank of premium gasoline, the more efficient four-cylinder can cover 546 miles between refuelings.

CT6 Sedan Interior

Luxurious style is the name of the game inside the large sedan, with soft-touch surfaces and lavish appointments abounding. Still, the Cadillac CT6 fails to meet the high-quality standard benchmark set by its European competitors. Comfort is also key, and the Cadillac doesn't disappoint with its advanced and user-friendly infotainment system and its supremely plush seats. There is enough space up front for drivers of any size, although you may still be tempted to sink into the opulently comfortable rear seats. The newly improved infotainment system is well laid out for better ergonomics and fewer headaches.

Seating and Interior Space

Spacious is certainly a word that can be used to describe the CT6. Able to seat up to five passengers, the cabin presents passengers up front with extremely generous legroom and ample headroom for even tall drivers. Naturally, there is less space in the back, especially with the sloping roofline, but it should still be more than enough for most full-size adults. With power-adjustability in just about any direction possible, finding the perfect driving position won't be a problem. Visibility isn't an issue, although it is supplemented by a rearview camera or a surround-view unit on higher trim levels.

  • Seating capacity
  • Front Leg Room 46.4 in
  • Front Head Room 40.2 in
  • Rear Leg Room 40.4 in
  • Rear Head Room 38.0 in

Interior Colors and Materials

As you'd expect from a luxury sedan, leather upholstery comes standard on even the base model, while semi-aniline leather with perforated inserts is the norm on the top-tier Platinum. A choice of Jet Black or Sahara Beige leather is presented on the Luxury, expanding to Dark Auburn on the Premium Luxury, with the option to add Chevron perforated inserts. The Sport is only available in the darker hues. The semi-aniline leather seats come in either Jet Black or Very Light Cashmere, also with Chevron perforated inserts. A variety of wood-tone-accented interior trims complement the upholstery. The cabin is extremely well-built and oozes style and opulence.

CT6 Sedan Trunk and Cargo Space

The trunk is not overly impressive for such a large sedan, with rivals like the BMW 7 Series and Mercedes-Benz S-Class each supplying quite a bit more room. Only 15.8 cubic feet of space is present behind the rear seats of the CT6, which do not fold down as they do in many similar large sedans. The front of the trunk is wide, but it narrows as it approaches the wheels, further adding to its inability to store large-dimension items. Still, it is adequate for daily usability, with space enough for half a dozen carry-ons.

The large infotainment system takes up a lot of space that could otherwise go towards small-item storage, but the cupholders and center armrest help to make up for it. The door pockets are deep and the glove compartment is more than adequately sized.

CT6 Sedan Infotainment and Features


Standard features comprise dual-zone climate control, cruise control, keyless entry and ignition, 14-way power front seats with two-way lumbar, a power tilt-and-telescoping steering column, a wireless charging pod, a teen driver system, front and rear parking assist, and a rearview camera. Extra features added further up the trim levels include 20-way power front seats with memory functions, heated and ventilated front seats, a head-up display, and rear auxiliary power outlets - and, as a bonus, massage settings on the front seats. Advanced safety features available include a safety alert driver's seat, a heated steering wheel, a surround-view camera, rear pedestrian alert, rear cross-traffic alert, various lane-keeping assistance features, blind-spot monitoring, and the Super Cruise driver-assistance feature.


A 10.2-inch touchscreen display comes standard with two USB ports, Bluetooth, Apple CarPlay and Android Auto, a 4G LTE Wi-Fi hotspot, and an eight-speaker Bose audio system that supports AM/FM/MP3 playback and SiriusXM. A ten-speaker and 34-speaker sound system are made available on upper trim levels, along with a rear entertainment system that includes dual ten-inch monitors, HDMI input, dual USB ports, and two headphone sets. For 2019, Cadillac did away with the previously frustrating-to-use trackpad in favor of a more intuitive clickwheel, which has made the system vastly more user-friendly.

CT6 Sedan Problems and Reliability

J.D. Power ranks the CT6 quite highly in terms of dependability, with a score of 85 out of 100 - only a few points below class-leaders. Two recalls were issued for the 2019 model, one for turn signals that didn't deactivate automatically, and one for faulty rear seatbelt retractors. Cadillac offers a 50,000-mile/48-month limited warranty and a 70,000-mile/72-month powertrain warranty. Roadside assistance is available for 70,000 miles or 72 months.

CT6 Sedan Safety

The large luxury sedan has not been evaluated by the NHTSA or the IIHS for crash-test safety, but the upper trims come equipped with an extensive list of advanced safety features.

Key Safety Features

Standard safety features comprise ABS brakes, a teen driver system, a rearview camera, front and rear parking assist, and eight airbags: dual front, front knee, front side, and side curtain. Additional features include automatic parking assist, a following distance indicator, forward collision alert, automatic emergency braking, a surround-view camera, lane change alert, blind-spot monitoring, lane keep assist and lane departure warning, and rear cross-traffic alert.

Verdict: 🏁Is the 2019 Cadillac CT6 Sedan a good car?

The luxury sedan segment is a demanding one, with established pack-leaders clinging tooth-and-nail to their positions on the podium. Still, the CT6 makes a valiant effort at giving its rivals a run for their money. Sadly, Cadillac focuses too much in some areas while neglecting others, resulting in a sedan that feels less polished than its European competitors.

While it handles well for a luxury sedan, the CT6 six lacks the potent and refined powertrains that Mercedes-Benz, BMW, and Audi have equipped under the hoods of their flagship sedans. Similarly, the American manufacturer presents buyers with a spacious cabin, capable of seating even the tallest of passengers, but it is not as lavish as it should be, and the trunk takes a serious hit, offering several cubic feet less than rivals.

If there is a silver lining here, it is that Cadillac doesn't expect you to pay through the nose for a car that clearly isn't up to par with its $100k plus rivals. Don't get us wrong, the CT6 is a good car; it's just that, in the luxury segment, good simply doesn't cut it. Buyers expect excellence if they are going to lay out this kind of money and, sadly, the Caddy doesn't warrant that kind of investment.

🚘What's the Price of the 2019 Cadillac CT6 Sedan?

For a full-size luxury sedan, the Cadillac CT6 has a remarkably affordable starting price tag; getting behind the wheel of the Luxury trim will cost you just $50,495. Even the Premium Luxury, with its many additional features, can be picked up for as little as $58,095 in rear-wheel-drive, while the all-wheel variant will set you back around $62,595. The price does start to pick up quite a bit going beyond these two base trims as all-wheel-drive becomes standard and more powerful engines are installed, with the Sport costing $66,595. The top-of-the-range Platinum is priced like a true luxury sedan at $86,795. These prices are exclusive of tax, registration, licensing, or destination fees.

2019 Cadillac CT6 Sedan Models

The Luxury started as the entry-level model for the CT6, but was discontinued part-way through the year, with the Premium Luxury stepping up to take its position. Both models started off with the 2.0-liter turbocharged four-cylinder, which delivers 237 hp and 258 lb-ft to the rear wheels. However, this engine was dropped later during production in favor of the 3.6-liter V6 engine, which develops 335 hp and 284 lb-ft and comes standard with all-wheel-drive. The Sport and Platinum trims are equipped with a 3.0-liter twin-turbo V6 as standard, producing 404 hp and 400 lb-ft for all four wheels. While, later in the production cycle, a powerful 4.2-liter twin-turbo V8 was made available to the Premium Luxury and Platinum trims. This Blackwing engine develops an impressive 500 hp and 553 lb-ft. Every powertrain comes mated to a refined 10-speed automatic transmission that seamlessly rows the gears.

The base Luxury is equipped with 18-inch alloy wheels, LED headlights, leather upholstery, a 10.2-inch touchscreen, Bluetooth, Apple CarPlay and Android Auto, and front and rear parking sensors.

The Premium Luxury, which would become the entry-level model, adds automatic parking assist, a surround-view camera, blind-spot monitoring, rear cross-traffic alert, lane keep assist features, and two extra speakers for the sound system.

The Sport trim adds unique styling elements such as a sport grille, a rear spoiler, and a carbon-fiber deco interior trim.

The top-tier Platinum rounds out the features with a 34-speaker Bose Panaray sound system, quad-zone climate control, extra advanced safety features, and Cadillac's refined Super Cruise technology.

Additional Packages

Although the sedan comes equipped with an impressive list of features as standard, there are still a few noteworthy packages available. The Driver Awareness Package for the base Luxury adds a safety alert driver's seat, a following distance indicator, forward collision alert, rear cross-traffic alert, lane keep assist and lane departure warning, lane change alert, blind-spot monitoring, and automatic emergency braking. The Rear Seat Package ($2,700) for the Premium Luxury comprises quad-zone climate control, an air ionizer, a rear-seat infotainment system with dual 10-inch monitors, dual USB ports, and an HMDI input.

An exterior package is also available for the Platinum trim, which equips 20-inch Midnight silver alloy wheels and a rear spoiler for $3,995. For the Sport trim, an Active Chassis Package ($3,300) and the Super Cruise Package ($6,000) can be added on to include magnetic ride control and active steering, or the acclaimed Super Cruise Driver Assistance feature respectively.

🚗What Cadillac CT6 Sedan Model Should I Buy?

While the base-level Luxury is well-appointed and affordable, the Premium Luxury adds a significant number of advanced safety features without increasing the price too much. And with the Luxury trim dropped from the line-up part-way through the year, the Premium Luxury is now the cheapest model you can get. Still, it offers a good mid-way between the bottom and top rung. For those seeking a thrill, the 4.2-liter twin-turbo V8 is certainly appealing, and you may be able to pick it up on a secondhand CT6 - it is sold out for the current production year, however, the engine will be returning for the 2020 model.

2019 Cadillac CT6 Sedan vs Lincoln Continental

Much like the CT6, the Lincoln Continental is more of an affordable large luxury sedan, with a starting price of $46,145. While it comes with a stronger standard engine, in the form of a 305-hp V6, and optional engines that rival the CT6's, the Continental lacks the value provided by the Caddy due to its rather poor mileage figures. Similarly, while the Lincoln sedan offers competitive interior space and a more spacious trunk, the CT6 is better appointed and uses higher-quality materials. Getting the most out of the Continental will see you spending up to $80k, while you can get the same in the CT6 for around $60k. Overall, the CT6 is the better choice here; unless you're willing to spend close to $100k, in which case there are better options out there.

2019 Cadillac CT6 Sedan vs Cadillac CTS Sedan

The CTS is the smaller, sportier brother to the CT6. Needless to say, the smaller sedan handles better than the large cruiser, but you can expect to pay the usual price for this. The interior of the CTS is more cramped, especially in the rear seat, and the trunk is even smaller than the CT6's embarrassing cargo area. The standard 268-hp four-cylinder on the CTS lacks refinement, making it far less efficient than the one found under the full-size luxury sedan's hood, but the optional V-sport engine is eminently capable. Naturally, the luxury sedan offers a lot more bells and whistles than its little brother, but the more features you want, the more you're going to pay. However, with a relatively low starting price, the CT6 still seems like the better choice here if you want to balance luxury and performance.
