Cadillac Ciel Concept

The Cadillac Ciel Concept - pronounced "C-L," the French translation for sky - is a four-seat convertible that opens a new chapter in Cadillac's design and product ascent, pushing the brand's Art & Science philosophy into a new stratum. Ciel is a new expression of Cadillac's historical grandeur, as well as a celebration of open-air motoring.
"Large, expressive luxury is innate to Cadillac and the Ciel recalls that heritage, while suggesting where the brand can go in the future," said Clay Dean, global design director for Cadillac. "Authentic luxury is driven by experiences, not just products, and Ciel is about the experience of the journey."

The spacious and elegant Cadillac Ciel Concept is a grand gesture that explores themes driving Cadillac's explorations into range-topping flagship luxury. It is powered by a twin-turbocharged version of the 3.6-liter Direct Injection V-6 engine, paired with a hybrid system using lithium-ion battery technology.
Coastal inspiration
Driving California's Highway 1 in an open car while the sun sets, from Big Sur north to Monterey, is the type of journey the Ciel team envisioned during its design.
"The Ciel is about the romance of the drive," said Dean. "It emulates the great touring cars seen on the greens at Pebble Beach, but with a modern flair that projects Cadillac's vision for the future."
The four-door Cadillac Ciel Concept embraces the social aspects of a recreational journey, with generous room for two couples. It evokes the spirit of the classics with a long, low proportion. The doors are French-style, with the rear doors hinged at the rear - there is no B-pillar - to reveal a sweeping view of the dramatic interior. Distinguishing fender lines run from nose to tail, and nickel-plated bright work accents the body lines, enhancing the visual length of the car and honoring Cadillac touring cars of the past.
Cadillac Ciel Concept's exterior flows seamlessly into the cabin, with the body color rolling over on top of the interior door panels. Like the exterior, the passenger space is accented with sweeping nickel-plated trim. It divides the body-color upper sections from a complementing beige lower color. Italian Olive wood, machined aluminum and hand-tipped leather are elements that flow through the interior, complementing the primary colors with warm, rich tones.
"There is authentic craftsmanship in the way the exterior and interior elements meld, much like a vintage wooden boat," said Gael Buzyn, interior design manager. "It is romantic, not only in its form, but the materials - nothing smells as good as real wood and leather. It blends together for a rewarding feeling of uncompromising luxury."
Cadillac Ciel Concept literally and figuratively reflects the driving experience along the California coastline. The Cabernet paint color, developed specifically for Ciel, is inspired by the rich translucence of a glass of red wine held up to the sunlight.

A prominent, polished aluminum windshield frame serves as in important structural element of the vehicle, as well as aesthetic one, recalling classic open cars of the past. Additional exterior cues, including a shield grille and vertical lighting elements, are pure Cadillac, but suggest a more organic interpretation of the brand's signature design language that emphasizes the artistic and natural sides of it. The body sides, for example, are more rounded, sweeping upward. Bright work is used to bring contrast to the deep paint color, but plays a more supporting role.
The car rides on large, beautifully finished wheels that feature brushed nickel plating over milled billet aluminum, matching the materials and appearance of other trim. Carbon ceramic brake rotors are visible behind the 22-inch rims, a visual clue to the Ciel's foundation of performance.
And owing to Cadillac's heritage of advanced technology, the headlamps and taillamps feature LED lighting elements - including a unique daytime running light graphic on the front of the vehicle that is generated with gradated LED lighting.
Elegant, authentic details
Simplicity, authenticity and spaciousness were the guiding principles when it came to developing the Cadillac Ciel Concept's interior.
"With the Ciel, the journey is the thing, so the interior is a place of uncompromising comfort and elegance, with technology that only makes the journey more enjoyable," said Buzyn. "Simplicity and lightness ensure nothing distracts from the open driving experience, while the color and materials lend the feeling that the vehicle's environment blends with the surroundings."
A wheelbase of 125 inches - about 12 inches longer than a CTS sedan - provides generous space. Luxurious seats are bisected by a "floating" center console that runs from the instrument panel to the rear of the interior. It effectively creates a very personal space for each passenger and houses access to hidden connectivity portals for each person in the vehicle - allowing them to make dinner reservations, check the weather at their destination or even upload photos of the trip via social media sights.
Simplicity is also the watchword with the Cadillac Ciel Concept's instrument panel, which features a minimalist gauge cluster that doesn't impede or distract from the outward view. But while reserved in its form, it exemplifies Cadillac's attention to details and its priority on authentic materials. The climate vents, for example, are mostly hidden and their airflow is distributed indirectly.
Transparent gauges deliver their information within a detailed, brushed-aluminum housing that has the intricate depth of a high-quality chronograph. They offer dual readouts - analog and digital - as well as an information hierarchy. Additional interior features include:

• Sloping bolsters on the seats that allow passengers to slide into the seats more comfortably
• A personal device storage area on the front of the console with inductive charging and Bluetooth connectivity
• A power-assisted transmission shifter that deploys as soon as the engine is started
• Lighting in the armrests that combines a natural light well for daytime driving and ambient lighting for nighttime drives
• Door storage areas that are inspired by premium fashion accessories and open with high-quality zippers
• Pull-out blankets are available for all three passengers and retract automatically
• All the seats have heating and cooling features, along with a drawer containing sun lotion, sun glasses and towels, as well as aromatherapy that is controlled from the rear armrest.

But perhaps the defining element of the Ciel's cabin is the incorporation of Italian Olive wood on the doors, instrument panel, console and the front seatbacks, adding warmth and craftsmanship to a car designed to provoke an emotional response.
"Milled solid wood delivers richness and a sensual feeling of authenticity in the visual impact of the grain, its feel and aroma, which a veneer simply cannot," said Buzyn. "Even in our high-tech, connected world, luxury customers crave touches of old-world craftsmanship - the Cadillac Ciel Concept simply reflects that with a blend of the latest technology."
Italian Olive wood is a premium yet sustainable material and the material used in the Ciel came from a single fallen and recycled tree, from a west coast producer of premium olive oil. It was painstakingly prepared, including drying in a kiln, before it was cut for the concept vehicle. The numerous pieces were then photographed so that the grain could be matched precisely. Each component was hand-milled and finished by expert woodworking craftsmen.
The rear seating area is detailed with elegant flourishes. The rear seat passengers can pull a leather tab, which reveals a cashmere blanket that stretches across the seating area to ward off a chill. The wood trim in the rear center console opens to reveal a small humidor, stocked with a few cigars.
"From the materials used to create it to the space and experience it offers passengers, the Cadillac Ciel Concept represents a unique perspective on luxury, but not the only one," said Dean. "Along with other concepts, such as the ULC, Cadillac is demonstrating that the bandwidth of the Art & Science philosophy is wide, indeed - and we're going to make it even wider."
The Cadillac Ciel Concept was developed at GM Design's North Hollywood Design Center, which is managed by Frank Saucedo. Niki Smart was the lead exterior designer, with Buzyn leading interior development.

Cadillac SRX

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.
Cadillac 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 Cadillac 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.

Cadillac 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."

Inside the LFX
The Cadillac 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 Cadillac 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 Cadillac 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.
Cadillac 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.
