Cadillac’s current flagship

After years of leaks, spy shots, and endless rumors about its feasibility, the Cadillac CT6 became reality at the 2015 New York Auto Show. A replacement to the XTS, the CT6 arrived to compete against Germany’s luxury trio, which includes the Mercedes-Benz S-Class, BMW 7 Series, and Audi A8. However, Cadillac also wants the CT6 to go against midsize European sedans.

The odd positioning strategy makes the CT6 similar in size to any European luxury car, as its length and wheelbase are on par with those of a BMW 7 Series short-wheelbase. On the other hand, thanks to an aluminum-intensive platform, the model weighs about as much as the smaller CTS, which is lighter than a 5 Series. Whether Cadillac’s strategy will work in the long run remains to be seen, but the CT6 seems to tick a lot of right boxes.

Likely to improve interior headroom, the side is more generic-looking, especially the greenhouse.

Even though everyone was expecting the CT6 to be based on the Elmiraj Concept’s styling, GM design boss Ed Welburn made it clear that it wasn’t. Instead, the model features a more evolutionary progression of the current Art and Science design theme of the CTS and ATS sedans. While that is sort of a letdown, the CT6 is far from looking derivative. Unlike the XTS, which will be be kept alongside the CT6, the new Cadillac flagship features a much more pronounced dash-to-axle ratio and a short front overhang, which emphasize the model’s rear-wheel drive and classic luxury-car proportions.

The front end looks like it has been chiseled out of solid block, while the vertical headlights frame the distinctive engine grille in a similar way to the CTS and ATS. Likely to improve interior headroom, the side is more generic-looking, especially the greenhouse. Likewise, the rear end is typical modern Cadillac, and no extra lines disturb the otherwise clean and angular styling.

The center console features a 10.2-inch capacitive touchscreen display, while a smaller one takes the classic instrument cluster's space.

This is where the CT6 differentiates itself more from the lineup, even though the dreaded CUE infotainment system makes another appearance. Cadillac boasts that the model has best-in-class interior storage, including a 2.2-liter center console storage volume, although I fail to see how important this detail is for luxury-car buyers. The center console features a 10.2-inch capacitive touchscreen display, while a smaller one takes the classic instrument cluster’s space. If you don’t want to touch the large display on the console there is also a smaller touchpad on the arm rest. Modern gizmos like a 360-degree camera view around the vehicle or a night vision system that can detect people and large animals are also present, but Cadillac takes those up a notch.

The carmaker says that the CT6 features the "industry’s first application of full-display technology," which is a fancy way of saying that the conventional interior mirror is combined with the rear camera to give an unobstructed view of the rear. The 360-degree camera system can also record front and rear views while driving, or all-round view when the car’s security system is activated. There is also a quad-zone climate control system, while the audio system is from Bose and features 34 speakers placed around the cabin.

Cadillac is also debuting two technologies new to the automotive industry.

First is the ability to connect a video streaming device into the car’s rear-seat entertainment system for viewing programming from site like Hulu, Netflix, and YouTube. This is done via devices like Google Chromecast, Amazon Fire TV Stick, and Apple TV. These devices communicate with the user’s smart phone or tablet via the CT6’s in-car Wi-Fi network, just like the user would do at home. Now rear passengers can enjoy a Netflix and chill session while on the move. How convenient.

Next is a potentially more bacon-saving technology. The CT6 will now record the video from four of its six outside cameras onto an SD card located in the trunk. Like GM’s Performance Data Recorder in the Camaro, Corvette, and V-series Cadillacs, the user can download the video onto a personal computer for safe keeping. The system can also be programmed to activate should the car’s security system become armed. Cadillac says the video feed is pulled from four cameras is recorded in a “round-robin fashion.”

For drivers who want to record video on the move, the system simultaneously records from both the front and rear cameras. Cadillac says owners could use this to record a memorable drive. We say this is a perfect built-in dash cam for evidence in a crash or just awesome video footage for YouTube. Let’s hope this sparks a growing trend among automakers.

The twin-turbo, 3.0-liter V-6 cranks out a whopping 404 horsepower and 400 pound-feet of torque

Cadillac made sure that the CT6 has what it takes to go against the big boys drivetrain-wise. The big sedan can be had with one of three engines, starting with a small but fuel-efficient 2.0-liter four-cylinder. The turbocharged cranks out 237 horsepower and 258 pound-feet of torque and mates to a 10-speed automatic transmission. It comes standard with an automatic stop/start function. This engine wasn’t offered from the very beginning though, as it debuted for the 2019 model year.

Next up is GM’s traditional 3.6-liter V-6. This naturally aspirated engine generates 335 horsepower and 284 pound-feet of torque, more than enough to compete with entry-level versions of the German sedans. Originally offered with an eight-speed automatic, the V-6 was later paired to a 10-speed speed gearbox.

The range-topping CT6 gets its juice from a more modern, twin-turbo, 3.0-liter V-6 powerplant. It cranks out a whopping 404 horsepower and 400 pound-feet of torque and mates to the same 10-speed automatic as the rest of the engine lineup. It also features an automatic stop/start system for improved fuel economy.

The CT6 retailed from $53,495 when it was initially unveiled for the 2016 model year. The base model came with the 2.0-liter engine under the hood. For the sedan equipped with the 3.6-liter V-6, the sticker was set at $55,495. Finally, the range-topping twin-turbo sedan retailed from $64,395 before options.

Come 2019 and the CT6 is a bit more affordable. The base model now retails from $51,490, while the 3.6-liter version comes in at $56,490 before options. Opt for the least expensive twin-turbo V-6 variant and you need to pay $67,590. The range-topping Platinum model with the same engine retails from a whopping $87,790.

Mercedes-Benz S-Class

Unfortunately for Cadillac, the Mercedes-Benz S-Class seems to be in another league than CT6, despite the two models sharing similar dimensions and being called "flagship sedans." First of all, the S-Class’s least-powerful engine available on the U.S. market is a twin-turbocharged, 4.7-liter, V-8 that delivers 449 horsepower and 516 pound-feet of torque. So the least powerful engine in the S-Class is more powerful than the top engine in the CT6, although that may change, since Cadillac hinted that a twin-turbo V-8 is also on the way.

Also, the CT6 still has to make a name for itself, while the S-Class has a history going back to the 1950s, and most of today’s safety or comfort features debuted on the German luxury sedan. In the end, it is all a matter of choice in this segment, but the S-Class is one tough mountain to climb and not even BMW or Audi have managed to dethrone it so far. You can read our full review of the S-Class here.

Audi A8

Just like the Cadillac CT6, the Audi A8 tries to follow a new approach compared to established models in the luxury segment. With an exterior design that could be easily switched to that of an A6, or even an A4, the biggest Audi sedan is not exactly the most distinctive-looking model in the range, but it does look like no other luxury car. Unfortunately, both the S-Class and especially the lighter CT6 may have the A8 beat in terms of dynamics, since the Audi is based on a front-wheel-drive architecture despite featuring AWD as standard (in the U.S.).

On the plus side, it looks more inconspicuous than any of its rivals, meaning that those who require a less ostentatious luxury sedan can always go for the A8. You can read our full review of the model here.

While the Cadillac CT6 doesn’t break any molds, it does bring a new take on the luxury sedan, one based on lightness and agility combined with the unmistakable Cadillac Art and Science design language. It’s not overly flamboyant, like the Cadillacs of old, but it does have presence, and the list of comfort features is long enough. I would have enjoyed more cylinders to go with that light chassis and long hood, and some design motifs of the side and rear could have a more dramatic look for this day and age, but overall I’m far from disappointed with the new CT6.

  • Leave it
    • Looks a bit generic
    • Not exactly ground-breaking technology
    • It’s not a full-on rival for German luxury cars

Press Release

Cadillac tonight held the world premiere of the 2016 CT6, elevating it to the top of its range and creating a new formula for the prestige sedan through the integration of new technologies developed to achieve dynamic performance, efficiency and agility previously unseen in large luxury cars.

CT6 marks Cadillac’s long-awaited return to the global prestige luxury segment, and is one of eight all-new vehicles the brand will launch by the end of the decade as part of its $12-billion product investment to expand and elevate.

“The CT6 is nothing less than an entirely new approach to premium luxury – and an approach only Cadillac can offer,” said Johan de Nysschen, president of Cadillac. “It is a bold endeavor with unmatched dynamism that reignites a passion for driving in large luxury vehicles. In short, it is prestige luxury reimagined.”

Cadillac CT6 takes drivers to a higher threshold of involvement, with technologies that make them more aware of their surroundings, chassis systems – including active technologies – that make the most of control in all conditions, and powertrains led by an all-new Cadillac Twin Turbo engine that rewards with stirring power on demand. Passengers are ensconced in the brand’s ultimate expression of comfort, luxury and connectivity.

The CT6 features one of the industry’s most advanced automotive body structures, an aluminum-intensive architecture that incorporates 11 different materials to achieve strength, performance and efficiency thresholds practically unmatched among the world’s elite luxury performance sedans.

It is one of the world’s lightest and most agile full-size luxury performance sedans, with dimensions and spaciousness on par with BMW’s short-wheelbase 7-Series, but the approximate weight, agility and efficiency of the smaller Cadillac CTS – which is lighter than a BMW 5-Series. The CT6 is lighter than the BMW 5-Series, 6-Series and Mercedes-Benz E-Class.

“We reinvented the approach to structural underpinnings in the quest to develop a unique formula for the prestige luxury performance sedan,” said de Nysschen. “Melding that new approach with the dynamics conveyed in our other award-winning rear-driven sedans – including V-Series – results in something that has been lost in the segment: the exhilaration of a true driver’s car.”

Cadillac focused on three pillars that would coalesce to deliver the CT6’s dynamic experience – and do so with higher levels of presence, elegance and technological innovation to help elevate Cadillac around the world.

“Luxury brands are built from the top down,” said Cadillac Chief Marketing Officer Uwe Ellinghaus. “Adding a dynamic, top-of-the-range car is central to Cadillac’s elevation and global growth.”

About the architecture
The body-in-white of the 2016 Cadillac CT6 is structurally lighter and stiffer than any other dynamically similar vehicle such as the BMW 5-Series or Audi A6. That state-of-the-art architecture is the foundation for its benchmark-establishing agility and vault-like solidity and quietness.

The new architecture has a mixed-material structure with all-aluminum exterior body panels. Engineers conducted 50 million hours of computational analysis – including 200,000 structural simulations – in its development, generating 21 patents.

“Every panel of the body-in-white is optimized with innovative joining techniques,” said Travis Hester, executive chief engineer, Cadillac CT6. “It’s an uncompromising approach that provides the best balance of strength, lightness and refinement.”

Thirteen high-pressure aluminum die castings in the lower body construction reduce complexity and are significant contributors to the architecture’s low mass. The CT6 is approximately 218 pounds (99 kg) lighter than a comparable vehicle using predominantly high-strength steel.

GM’s most advanced body manufacturing methods are used to fabricate the structure, including proprietary aluminum spot welding technology that is more efficient and helps reduce weight. Laser welding, flow drill fasteners and self-piercing rivets are also employed, along with roughly 591 feet (180 meters) of advanced structural adhesives.

Chassis and suspension highlights
The CT6’s rigid, lightweight architecture is the foundation for its segment-challenging agility, enhanced by active-on-demand all-wheel drive, active rear steering and Magnetic Ride Control on the available Active Chassis System.

“To put it succinctly, every wheel drives and every wheel steers,” said Hester. “And with Magnetic Ride Control, every wheel’s dampening is adjusted by the millisecond, for responsiveness and driver control unparalleled in the segment.”

2016 Cadillac CT6

The chassis system also balances responsiveness with segment-best isolation for exceptional refinement. In the front, the CT6 features a lightweight, aluminum-intensive high-arm multilink short-long arm front suspension. At the rear is a five-link independent suspension that uses multiple outer ball joints and cross braces for optimal handling and steering precision.

Active rear steering with the Active Chassis System contributes to greater low-speed agility and high-speed stability. In parking lots, the turning circle is only 37 feet (11.4 m), comparable with the CTS, which has a 114.6-inch wheelbase vs. the CT6’s 122.4-inch wheelbase.

Active-on-demand all-wheel drive is also part of the Active Chassis System, making the most of handling and stability in all weather conditions. Its lightweight, compact design and two-gear transfer case enable greater fuel economy than conventional fixed-torque all-wheel drive systems. All-wheel drive is standard on all CT6 six-cylinder models.

Selectable Tour, Snow/Ice and Sport modes allow the driver to tailor the CT6’s advanced chassis system for practically any weather or road condition.

Bold proportions, exquisite attention to detail
A bold proportion dominated by a long hood and sleek upper body distinguishes the CT6, evolves the brand portfolio and reinforces the agility enabled by the lightweight architecture.

“This is a car designed for passionate drivers,” said Andrew Smith, executive director, Cadillac Global Design. “CT6 is low, wide and sleek, which is just what you’d expect in a lightweight performance sedan. There is a great dash-to-axle proportion that reinforces the dynamics of the rear-wheel-drive architecture.”

The “face” of Cadillac evolves with the CT6 through new executions of the grille and signature lighting elements. The vertical light signature, for example, features new LED light blades that frame the front of the vehicle, with forward illumination from technologically advanced Indirect Fire LED headlamps.

Proportion, craftsmanship and technology also define the CT6’s cabin. Cadillac designers aimed to deliver a bold, elegant and spacious interior. That elegance is expressed in curated environments and in surface sculpture featuring authentic materials, exquisite details and elevated executions of the brand’s signature cut-and-sew interiors. The CT6 uses state-of-the-art technology to reward its occupants with high levels of comfort, connectivity and safety.

“Never before has such craftsmanship and technology been so seamlessly interwoven,” said Smith. “The CT6 represents our next step in the continuing evolution of the Cadillac brand portfolio.”

Production and manufacturing
Production of the 2016 Cadillac CT6 begins at the end of 2015 for the North American market at the Detroit-Hamtramck assembly plant, which underwent a $384-million investment in tooling and other upgrades to support the manufacture of the CT6 and two other products. Chinese-market models will be assembled at an all-new facility in China starting in early 2016.
