Cadillac CT6 Plug-in Hybrid Version Unveiled

IMG_3485-0.JPGAs expected, Cadillac is slowly releasing ever greater detail about their new flagship CT6 sedan.

This time, we have the long-rumored plug-in hybrid variant.  Combining the best of GM’s electric vehicle technology with a 18.4kWh lithium ion battery constructed of cells similar to those in the recently updated ELR and 2nd generation Chevrolet Volt, dual electric motors, and what Cadillac is calling an “Electric Variable Transmission”.  The electric powertrain combines with Cadillac’s 2.0l turbo 4-cylinder to deliver 335hp and 432 lb*ft of torque.

Cadillac is surprisingly calling this their ‘first plug-in electric hybrid’ – surprising until you realize that GM insists on referring to the Volt and ELR as ‘extended range electric vehicles’.  This is a distinction that may confuse the average consumer but center on how power makes it from the gas engine to the drive wheels.  CT6 will use the EVT transmission to blend power from the turbo engine along with electric propulsion from the twin electric motors.  In the ELR, the wheels are driven almost exclusively by the electric motors with the gas engine driving a generator to provide power when the battery runs flat.

Similar to the ELR, though is the CT6’s regeneration on demand system, where paddles behind the steering wheel allow the driver to increase how aggressively the vehicle’s control systems turn motion back into electricity (through running the electric motors as generators).  The CT6 also apes the ELR with normal, sport, and hold modes.  Hold allows the driver to reserve battery charge to use later in the drive – running exclusively on gas power until taken out of hold mode.  Normal and sport are the expected modes that control suspension and steering settings alone.

All of this technology is promised to bring with it some impressive numbers.  Cadillac is claiming that the MPGe (a number from the EPA that attempts to equate electric assisted vehicles with gas powered vehicle efficiency) of the CT6 will be over double the mileage numbers of any other powertrain offered, almost certainly the 2.0l turbo without the electric assist.

Let’s Talk CT6

CT6On March 31st, 2015, in the evening before the opening of the New York Auto Show press days, Cadillac unveiled its long awaited flagship.

In many ways it turned out to be what we expected…in others, not as much.

As expected, the new flagship is direct competition with the German big sedans.  However, that’s far from the end of the story.

Based on GM’s new Omega rear-drive platform, the CT6 is significantly larger than its smaller siblings.  It is within fractions of the size of the short wheelbase Mercedes S-Class and BMW 7-Series.  However, in keeping with Cadillac’s recent track record of being more dynamically focused than the competition, the CT6 ends up lighter than the mid-sized competitors (yes, that means the big Caddy is lighter than an E-Class or 5-Series).

CT6 InteriorWe knew Cadillac was going to build a technology demonstrator in the CT6 – but surprises came in the form of standard AWD (with the 6-cylinder powertrains), a touch-pad enhancement to CUE to allow handwriting recognition input, all-wheel steering that gives the big car a turning radius that beats the new CTS, and the powertrain surprise wasn’t the expected plug-in hybrid but a base engine in the form of a turbo 4.  Yes, the Cadillac flagship has nary a V-8 to be found with the top engine (for now) being a 3.0l turbo V-6 with 400hp.

Staking a unique position (geez, what’s happened to you BMW?) the CT6 is a driver’s car with its emphasis being squarely on driving dynamics. Continue Reading →

CT6 Revealed

IMG_3485.JPGSized like a 7-Series short-wheelbase (can a long wheelbase CT7 be far behind?), but lighter than a 5-Series. 

The CT6 looks to be the drivers’ big sedan, fighting the impression many have that Cadillac builds big, heavy ‘land yachts’.

More details soon.

Cadillac CT6 to Debut 34-Speaker Bose Panaray Audio as Top Option


In order to compete with big boys at the top of the luxury sedan market, Cadillac recognizes that luxury also includes high-end audio. 

Today, Bose announced the CT6 would feature the first automotive application of their Panaray audio line. 

Base CT6 models will have an 8 speaker Bose system, mid range stereos will come with 10. 

The full-boat Panaray will come with no fewer than 34 speakers. 

Panaray uses this large speaker count to direct exactly the sound needed in exactly the direction desired. A motorized bank of 3 1″ speakers rise from the center dash, a pair of 2″ speakers reside in the center rear. As shown in the picture above, you can see speakers in headrests, and scattered all over the flagship’s cabin. 

It promises to be both an expensive and impressive audio experience. 

Press release below:

FRAMINGHAM, Mass.–()–Thirty-five years ago, Bose and Cadillac defined premium automotive audio, forever changing how people listen to music in a vehicle. And today, Bose introduces its most advanced and highest-performing automotive sound system since then — the Bose® Panaray®system, designed exclusively for Cadillac’s CT6 sedan.

The 2016 CT6 is a first in its segment, combining the prestige and technology of a range-topping vehicle with the dynamics and efficiency of a smaller one. Its Panaray system marks the global debut offering of Bose Automotive’s new line of “Advanced Technology Series” sound systems, and integrates technologies and design elements from Bose home entertainment and professional audio products to deliver unprecedented performance in a car.

“We asked Bose to create something truly special for this new vehicle: a sound system unbounded by limits, providing an audio experience that hasn’t been matched in any other luxury automobile,” said Travis Hester, Cadillac CT6 executive chief engineer. “Cadillac CT6 customers will be elated by what they hear and feel when they switch on the Bose Panaray system.”

The Bose Panaray system reproduces music with more clarity, precision, and deep bass than any other system preceding it. It combines advanced, proprietary Bose digital signal processing with 34 speakers — nearly all measuring less than 4 inches (100mm) in diameter — strategically positioned throughout the Cadillac CT6 cabin.

“There are no short-cuts to this kind of performance,” said Marc Mansell, vice president, Bose Automotive Systems Division. “The Bose Panaray system uses a bold design architecture, and it was made possible by continuous, relentless research. That’s how we established the category with Cadillac over three decades ago. We were obsessed with performance then, and we still are.”

First Automotive Application of Bose Home & Pro Speaker Designs

Bose automotive engineers drew inspiration from Bose sound systems designed for the home, public spaces, and some of the world’s most famous live music venues.

Bose professional products use articulated arrays — a series of small speakers set in alternating directions — to produce sound at a wider angle, creating a broader and more consistent sound stage for the audience. This design is applied for the first time in an automotive system with the dual tweeters located in the A-pillars and rear doors of the CT6.

Bose engineers then integrated line arrays, also used in Bose professional systems and home entertainment systems. These clusters of small speakers point in the same direction — focusing sound directly on the listener instead of relying on reflective surfaces. Line arrays are located in the CT6 center instrument panel (IP) and rear-center console.

The center IP array includes a cluster of three 2-inch (50mm) speakers housed in a first-of-its-kind motorized centerfill enclosure that rises out of the dashboard when the Panaray system is activated for remarkably precise music reproduction up-front, complemented by a 4-inch (100mm) speaker in each corner of the IP. The rear-center array includes a pair of 2-inch (50mm) speakers for optimal sound imaging in back.

Powerful New Bass Box Designs to Minimize Vibration

The Bose Panaray system delivers powerful bass performance without distortion, rattle, or unwanted vibration inside the CT6 cabin, even at the highest volume settings.

Several compact high-excursion woofers — the same kind found in Bose home entertainment systems — were combined with a new bass box design that produces the low-note output of a much larger enclosure.

Two Bose PowerProfileTM Low Frequency Enclosures, custom-engineered exclusively for the Cadillac CT6, are built into the floor under the driver and front passenger seats. Bose PowerProfile enclosures measure just over 3.5 inches (9.25 cm) high, and contain four 2.75-inch (70mm) speakers mounted side-by-side and back-to-back to maximize the distribution of low frequencies without shaking and buzzing.

Additional Panaray system bass sources include 4-inch (100mm) speakers in each front and rear door — housed in ported enclosures — and an upgraded 10-inch high-power Nd® woofer mounted on the CT6 rear shelf between a pair of 2.5-inch (60mm) rear-fill speakers.

“The bass performance of the Panaray system is more than heard — it’s felt,” Mansell said. “But true to Bose, it’s not exaggerated or boosted. It’s as real as it gets.”

Advanced Digital Signal Processing and Software

The Bose Panaray system is driven by a new amplifier platform with nearly twice the processing power of previous Bose offerings. New proprietary technologies running on the amplifier include:

  • Bose Centerpoint® 3 technology, upgraded for the Panaray system, featuring 12 channels of stereo-to-surround digital signal processing — twice that of the previous version. Centerpoint 3 signal processing uses a proprietary Bose algorithm to analyze the stereo signal and convert it into multiple channels, enabling greater detail when reproducing music from nearly any source.
  • Bose Advanced Staging Technology, bringing listeners closer to the feeling of a front-row concert by replicating the acoustic separation between instruments and vocals.
  • Improved Bose TrueSpace® signal processing, which works with each pair of Bose UltraNearfieldTM headrest speakers built into the driver and passenger seats.
  • Enhanced Bose SurroundStage® technology, delivering a balanced, 360-degree sound field for each passenger position in the CT6, while compensating for off-center seating.

The CT6 includes three levels of Bose sound, with the Panaray system available in higher-tier packages. A 10-speaker Bose Centerpoint surround sound system and an 8-speaker Bose system is also available. Option packages and pricing will be available from Cadillac closer to vehicle launch.

Cadillac Announces New V-6s for the CT6

As we get closer to the official unveiling of the flagship CT6 sedan, Cadillac keeps releasing technical details about what will make the car worthy of its status as a S-Class/7-Series/A8 competitor.

Now we know that the V-6 models of the CT6 will now simply bring to bear the existing 3.6l V-6 or twin-turbo engine found in the ATS-V and CTS vSport.  It will bring a brand new 3.0 twin-turbo and normal aspirated 3.6.

Cadillac is pitching these as part of a brand new V-6 architecture that bring the level of sophistication not only unseen in modern Cadillacs but also superior to the competition’s V-6 power trains.

Specifically these engines are significantly quieter than Audi’s 3.0 turbo and Infiniti’s VQ-series V-6 engines.

The 3.0 TT will pack 400hp and 400 lb*ft of torque – out powering similar engines from BMW and Audi.  The 3.6 will replace the similar sized engine Cadillac has been using in many of their sedans and coupes and will supply 335hp and 284 lb*ft of torque.  Both engines bring cylinder deactivation in order to maximize fuel economy (the 3.0 being the first combination of the technology with turbocharging).

Expect these engines to debut in the CT6 but to find homes in other Cadillac models in the coming months.

The CT6 will debut at the New York Auto Show in a little over a week.

UPDATE: Johan de Nysschen Answers Questions at Jalopnik

Cadillac head, Johan de Nysschen accepted an invitation to answer questions posed by the readers of after last night’s debut of the CT6 during a commercial aired during the Oscars. 

Interesting insights are confirmation that a sub-ATS car is on the way that will also be based on the Alpha platform and be rear and all-wheel drive.  Also revealed is that Cadillac is indeed working on a turbo V-8 that will see duty under the CT6 hood and will top a range of engines that will range from 4-cylinder turbo up to the fire-breathing V-8.  In the power train revelations were that all 4-cylinder options will soon be turbos, marking the end of the 2.5l 4 in the ATS.
