Cadillac Extends the Top of its Range with CT6


Advanced technology creates a new formula for the prestige sedan

2015-03-31

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.

Cadillac SRX for 2012: More Power, Features

New 3.6L V-6 bolsters of one of the industry’s fastest-growing crossovers

DETROIT A new 3.6L V-6 – the segment’s most powerful standard engine – headlines updates to the 2012 Cadillac SRX. It enhances a combination of performance, technology and refinement that is resonating with more luxury crossover customers.

SRX retail sales rose 17.7 percent in the first half of 2011, building on a record-setting 2010 sales increase of 150 percent.

The new 3.6L – known by its “LFX” engine code – is the sole engine offered in the SRX. It delivers 16-percent more horsepower (308 hp / 230 kW) than the previous V-6 and provides greater low-rpm torque. Vehicle responsiveness is dramatically improved in all operating conditions – launch from a standstill, around town maneuvering in traffic, passing maneuvers and full-throttle acceleration. It is matched with the Hydra-Matic 6T70 six-speed automatic transmission, which features a driver-selectable Eco feature that alters the shift points and throttle progression to help optimize fuel economy.

SRX also brings enhanced features for 2012, as well as updates that make it quieter and more refined – including new sound-absorbing material placed strategically throughout the vehicle. The Base and Sport suspension systems have been revised to improve the ride quality.

“The improvements we’ve made to the 2012 SRX make an already great luxury crossover even better, giving our customers more performance and features,” said Don Butler, vice president of Cadillac Marketing. “Many of the changes are a direct response to consumer feedback, demonstrating Cadillac’s commitment to total customer satisfaction.”

Feature and content enhancements for 2012 include:

  • Standard Bluetooth phone connectivity on all models, with on-screen caller identification
  • OnStar Turn-by-Turn automated directions are loaded to the vehicle
  • Improved voice recognition for phone activation, navigation and radio station changes
  • A heated steering wheel on the Luxury, Performance and Premium Collections
  • Door lock switches on the driver and passenger door panels as well as the center console
  • Cruise control buttons on the steering wheel
  • Memory seat set – the occupant can set the seating position simply by pressing “set” and the number simultaneously
  • Backlighting for map lights in the overhead console
  • A new machined-face finish on the 20-inch wheels, which are standard on Performance and Premium Collections
  • Available all-ebony interior trim
  • One new exterior color available this fall: Xenon Blue Metallic.

Popular features returning for 2012 include a moveable cargo fence and large under-floor storage space in the rear, a liftgate that can be programmed to stop at different heights and the UltraView sunroof that covers 70 percent of the vehicle roof.

The new and enhanced elements that contribute to a quieter ride include new acoustic material in the upper instrument panel, front-of-dash area, the center console area and the inner fenders, as well as laminated glass used in the front side glass. There is also a new laminated structural barrier used under the second-row seat to block noise.

Inside the LFX

The SRX’s new LFX 3.6L direct-injected V-6 delivers an SAE-certified 308 horsepower (230 kW) and 265 lb.-ft. of torque (359 Nm), with efficiency-enhancing features including direct injection and continuously variable valve timing. Peak torque is achieved at only 2,400 rpm and is maintained through 5,300 rpm. The LFX is also E85 ethanol-capable.

“The development team was challenged to achieve 300 horsepower in the SRX and exceeded the target,” said Liz Pilibosian, chief engineer. “The horsepower and low-end torque of the 3.6L deliver greater power on demand at launch, on steep grades and when passing. The power band of the LFX engine also contributes to a better shift feel.”

The LFX engine is a technically advanced 60-degree V-6 with dual-overhead camshafts, continuously variable valve timing and direct injection. Supporting elements that contribute to its performance, refinement and durability include:

  • The cylinder block and cylinder heads are cast in aluminum for low weight.
  • A composite intake manifold saves approximately 5.5 pounds (2.5 kg) over the weight of a comparable aluminum intake. It also has a comparatively small radiated surface area to help it maintain excellent noise and vibration characteristics.
  • An integrated cylinder head/exhaust manifold design saves approximately 13 pounds (6 kg) per engine when compared with a comparable engine with separate head/manifold assemblies.
  • The cylinder heads include four valves per cylinder, with a dual overhead camshaft design incorporating infinitely variable cam phasing.
  • A forged steel crankshaft provides optimal strength in the bottom end, while the connecting rods are made of powdered metal that features a higher ratio of copper, which makes them stronger and enables them to be lighter.
  • The pistons are made of lightweight cast aluminum and feature a friction-reducing polymer coating on the skirts , as well as fully floating wrist pins, which also help reduce friction. Less weight in the pistons means less reciprocating mass in the engine, which in turn means less inertia and greater operating efficiency.
  • Pressure-actuated oil squirters drench the underside of each piston and the surrounding cylinder wall with an extra layer of cooling, friction-reducing oil.
  • A cast aluminum oil pan is stiffer to improve powertrain rigidity and reduce vehicle vibration. It bolts to the transmission bell housing as well as the engine block, eliminating points of vibration. Cast aluminum dampens internal engine noise better than a conventional stamped steel pan and is structurally stiffer.
  • Optimized-flow fuel injectors and the integrated exhaust manifolds/cylinder heads promote lower emissions.

To help achieve their performance goals, the SRX’s engineers redesigned the exhaust system with dual runners from the engine to a collection point farther rearward in the vehicle. The diameter and length of the pipes were specifically tuned to improve low-end torque from 1,200 to 3,000 rpm.

High-pressure exhaust pulses from each of the cylinders in the engine are timed to arrive at this collection point so that they phase together in a precise way. This tuning effect, which is called scavenging, literally pulls exhaust gases out of the engine by synchronizing high and low pressure pulses from each cylinder. Peak torque now occurs at a very low 2,400 rpm and remains high all the way through 5,300 rpm. The torque and power improvements were achieved while maintaining quiet performance.

“No stone was left unturned when it came to optimizing the airflow of the LFX, from the moment it enters the engine until it is expelled through the muffler,” said Pilibosian. “The exceptional airflow qualities enabled us to exceed the 300-horsepower target, while careful calibration of the dual continuously variable valve timing system and the exhaust system contribute to the engine’s great low-end torque.”

The LFX engine is paired with the Hydra-Matic 6T70 electronically controlled six-speed automatic transmission, with tap up/tap down driver control. A wide overall ratio spread of 6.04:1 allows a “steep” first gear, as well as a “tall” overdrive top gear for low-rpm highway cruising. Acceleration is maximized, as is fuel economy. Engine noise is also lower during cruising. Because of the wide ratio spread (6.04:1), first gear is a very high ratio, which provides brisk acceleration from a stop. Sixth, however, is an overdrive ratio, which keeps the engine revolutions as low as possible for highway cruising, reducing engine friction losses and improving fuel economy.

A driver-selectable Eco feature alters the shift points of the 6T70 to enhance fuel economy by up to 1 mpg. A clutch was added to the variable displacement air conditioning compressor to enhance fuel economy. The compressor is only run when needed and provides no drag when turned off.

Chassis and suspension

The SRX has a four-wheel independent suspension system and a standard rack-and-pinion hydraulic steering system – and offers a variable-effort, speed-sensitive steering system – with tuning biased for sport sedan-style driving and strong on-center feel. StabiliTrak electronic stability control is standard and works with the standard four-wheel-disc/four-channel-ABS braking system.

The core elements of the chassis and suspension systems include:

  • An independent MacPherson strut suspension system is standard on all models, featuring a direct-acting stabilizer bar and hydraulic ride bushings.
  • An independent “H-arm” rear suspension incorporates a lightweight hollow aluminum lower control arm and a hollow stabilizer bar.
  • Power-assisted rack-and-pinion steering is standard on Base and the Luxury Collections.
  • Power-assisted variable-effort and speed-sensitive rack-and-pinion steering system is standard on the Performance and Premium Collections.
  • A rear axle ratio of 3.39 is standard on all models.
  • A trailering package is available on the Luxury, Performance and Premium Collections and increases the towing capacity to 3,500 pounds (1,587 kg).

For 2012, the Base suspension offers greater ride quality that maintains excellent handling characteristics, thanks to new upper front strut mounts, improved shock valve tuning, new bonded bushings for the front stabilizer bar and new twin-tube rear shocks that provide greater road isolation.

The Sport active suspension – standard on Performance and Premium Collections – is also improved for 2012, with new front upper strut mounts, new shock valving, bonded stabilizer bar bushings and revised calibrations for this continuously variable real-time damping suspension system. Electronically controlled dampers at each corner “read” the road constantly to make real-time adjustments within milliseconds. They deliver the just-right damper rate for all road conditions, for greater comfort and a greater feeling of control. This system also increases damping during aggressive handling maneuvers to reduce the roll velocity and pitch velocity of the vehicle for a more confident feel.

SRX is also offered with an all-wheel-drive system that incorporates an electronic limited-slip (eLSD) rear differential. It not only improves traction in slippery road conditions, but it provides side-to-side torque transfer along the rear axle to enhance control during hard cornering. It was developed in partnership with Haldex, a leader in all-wheel-drive technology and the eLSD enables the AWD system to distribute torque from the front to rear axle, and also side-to-side, across the rear axle, sending power to the wheel with the greatest traction.
