2016 CADILLAC CT6

Advanced technology creates a new formula for the prestige sedan

NEW YORK – 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.”

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.

The CT6 also will be offered in Europe, Korea, Japan, Israel and the Middle East. Production for those markets begins at Detroit-Hamtramck in early 2016.

CADILLAC CT6 ELEVATES THE SCIENCE OF MASS EFFICIENCY

Cadillac will use an advanced mixed-material approach for the lightweight body structure of the upcoming CT6 range-topping sedan. The structure is aluminum intensive, but the new Cadillac also includes 13 different materials customized for each area of the car to simultaneously advance driving dynamics, fuel economy and cabin quietness.

The CT6 will debut March 31 at the New York International Auto Show and go into production late this year at General Motors’ Detroit-Hamtramck assembly plant.

“This is the rocket science of automobile construction and manufacturing today,” said Cadillac President Johan de Nysschen. “With the CT6, we used high-strength aluminum and high-strength steels; lightweight chassis components; we integrate aluminum and steel where it makes sense; we eliminate every gram of mass possible, while achieving world-class performance.”

Weight reduction helps improve fuel efficiency, contributes to desirable vehicle dynamics and aids in creating a more resilient passenger cell. Sixty-four percent of the CT6 body structure is aluminum, including all exterior body panels – and the mixed material approach saved 90 kg (198 pounds) compared to a predominately steel construction.

Thirteen complex high-pressure die cast components make up the lower structure of the CT6 body, along with aluminum sheets and extrusions. The vehicle underbody uses steel close-out panels on the lower structure to create a bank vault-quiet cabin without the added weight of extensive sound-deadening material, often used to compensate for aluminum panels in the occupant compartment.

“The structure of the CT6 is one of the most-advanced body systems we’ve ever produced,” said Travis Hester, Cadillac CT6 executive chief engineer. “The innovation surrounding our joining techniques have enabled us to create a vehicle structure with the highest torsional rigidity of any Cadillac while achieving one of the most mass-efficient vehicles in the segment.”

Cadillac in January revealed a series of high-technology material joining techniques that create a new methodology for assembling the CT6. These enabled engineers to design a completely new structure for which 21 patents are pending.

“This new construction approach has enabled us to produce a world-class vehicle that is larger in size and includes more standard equipment while achieving lower overall mass,” Hester said.

• High-strength steel is used strategically to reinforce the body structure, and is also used in conjunction with high-strength aluminum to create a safety cage surrounding the occupants.
• The structural portion of the B-pillar is constructed completely of high-strength steel, which was chosen to aid vehicle ingress, egress and visibility, in addition to mass savings and added cabin quietness.
• A high-strength aluminum impact bar was added to the rear of the vehicle, and a combination of high-strength aluminum and steel was used for front and side impact zones to further increase passenger safety in the event of collisions.

A combination of aluminum spot welds, steel spot welds, flow drill screws, self-piercing rivets, laser welding, aluminum arc welding and hundreds of feet of structural adhesive are all used in assembling the body of the CT6.
