2009 CTS-V: CADILLAC’S ULTIMATE EXPRESSION OF PERFORMANCE AND LUXURY

DETROIT – As the new CTS sport sedan earns accolades and new owners, Cadillac takes the next leap forward by premiering the 2009 CTS-V, the brand’s ultimate expression of performance and luxury.

Launching in the fourth quarter of 2008, the all-new CTS-V intends to combine the serious performance of an elite sports car with the poise and elegance of a prestigious luxury sedan. Part of Cadillac’s acclaimed V-Series of high-performance models, CTS-V delivers an estimated 550 horsepower (410 kW).

More than just power, CTS-V also includes a comprehensive suite of technical and design enhancements, including Magnetic Ride Control, an industry-first Performance Traction Management program and the addition of a new automatic transmission with paddle-shift control.

“The CTS-V represents the full extension of our design, technology and performance capabilities,” says Jim Taylor, Cadillac general manager. “The V-Series takes the award-winning CTS sport sedan and elevates it to a position within the club of the world’s most exclusive and capable cars.”

As an all-new version of the CTS sport sedan was prepared for 2008, Cadillac engineers and designers began to scheme a new CTS-V that would reach much higher in terms of performance and luxury. Through the original CTS-V, Cadillac proved it could develop a very potent, high-performance sedan. The challenge for the 2009 model was enhancing every aspect in a comprehensive manner, along with reaching higher performance limits.

Several key technical and design elements combine to transform the already highly capable CTS into the new V-Series. Like the existing CTS, the V-Series is the product of an intensive development process across North America and Europe, including famed test tracks and millions of miles of road. Supporting Cadillac’s ongoing global expansion, the 2009 CTS-V is planned to be offered outside North America for the first time, including exports to Europe, the Middle East and Asia.

Sophisticated technical enhancements
The 2009 Cadillac CTS-V features the world’s fastest-reacting suspension technology, Magnetic Ride Control (MRC). It uses shocks controlled by electro-magnets, rather than mechanical valves, greatly accelerating response time. Electronic sensors at all four wheels literally “read the road” every millisecond, making constant adjustments to damping to create virtually instantaneous and extremely precise control of body motions. This is of particular benefit for a high-performance sedan, helping to keep the car very composed during hard cornering, acceleration, braking and other dynamic maneuvers.

MRC technology first appeared on the Cadillac STS performance sedan and has been used on some of the world’s most celebrated cars, including the Chevrolet Corvette and a select few European sports cars.

Enabling the precise control expected in a high-performance sedan, the CTS-V features Performance Traction Management system, borrowed from championship racing teams. This technology uses advanced electronics to manage engine torque for optimal traction during acceleration. In situations such as acceleration from a stop or exiting corners, Performance Traction Management regulates torque delivery for the best possible launch.

Performance Traction Management uses the same sort of electronics as stability control programs such as Cadillac’s StabiliTrak system, but applies it in a different manner. Rather than monitoring and controlling wheel slip to assist in stopping or slowing the car, PTM regulates torque delivery to instantly match the available tire grip for maximum acceleration.

CTS-V also includes sophisticated braking and tire systems, in partnership with two companies renown for high-performance technology: Brembo and Michelin. Brembo brakes are at all four corners and include powerful, six-piston calipers in the front and four-piston calipers in the rear. Michelin worked with Cadillac engineers to develop its acclaimed Pilot Sport 2 (PS2) summer tire for CTS-V and its 19-inch wheels.

And, of course, there is the matter of power. It has increased nearly 35 percent for the ’09 CTS-V, via a new 6.2L LSA supercharged V-8 engine generating an estimated 550 hp (410 kW) and 550 lb.-ft. (745 Nm) of torque. The engine delivers this power with remarkable refinement. A sixth-generation Eaton supercharger minimizes the added noise previously associated with supercharged engines, and tightly controls intake air temperature for optimal performance.
Transmission choices include either a six-speed manual or an exclusive, six-speed automatic with steering-wheel-mounted paddle shifters. It is the first automatic offered on the CTS-V.

Accentuated design elements
The 2009 CTS-V extends Cadillac’s acclaimed design language, both inside and out. The V-Series includes all the elements of the CTS sport sedan’s well received cabin, while adding some elegant and purposeful accents.
V-Series will offer Recaro performance driving seats, providing excellent support for spirited driving and adding to the luxurious and purposeful interior. These new, 14-way adjustable performance seats include pneumatic bolster controls in the seat cushion and backrest.

A microfiber material is added to the steering wheel, seats and shifter, providing the soft feel and luxurious appearance of suede without suede’s inherent drawbacks of difficult care and moisture sensitivity. These accents on the steering wheel, seat inserts and shifter are elegant to the touch and help support high-performance driving.

The car’s integrated center stack is trimmed with a new Obsidian material that is also applied to the center console and door trim. Just like every CTS, the V-Series includes a hand-stitched instrument panel, door trim and center console. Leading-edge infotainment features, including a 40-gigabyte hard drive, advanced navigation system with a “pop-up” screen and Bose digital surround audio, extend to the V-Series, as well as factory-installed Bluetooth capability.
The exterior of the new CTS-V amplifies the assertive stance and elegant details of the standard car, and communicates the car’s remarkable capabilities. The dihedral Cadillac grille is larger to enable more air intake and features a satin finish. The raised hood encompasses the supercharged engine, and new front and rear fascias identify the vehicle as a V-Series. The car’s 19-inch wheels enhance its stance on the road.

The founding member of the V-Series, CTS-V was initially offered in 2004 and sold primarily in North America through the 2007 model year. The supercharged STS-V and XLR-V were added in 2006 to make the V-Series an exclusive trio of models all capable of zero-to-60 acceleration in less than five seconds with enhanced overall performance and luxury features.

Maybe I'll just buy this one??? NHAHAHAHA!!!

It does exist! All this stuff we heard months and months ago could be true...could very well be true.

[stovt001]

So I wonder what this new tranny is. I'm looking forward to the V version of the upcoming 3 series fighter. Maybe that will be somewhat affordable somewhere down the line.

Sounds like it should be an amazing performer - and at least, it solves the paddle shift/console shift issue with some people: give it both!

ALL-NEW CTS-V TARGETS 550 SUPERCHARGED HORSEPOWER WITH CADILLAC’S SIGNATURE REFINEMENT

DETROIT – The all-new, 2009 Cadillac CTS-V blends exceptional performance with uncompromising refinement and its unique, 6.2L supercharged V-8 engine is, perhaps, the most dramatic example of the performance sedan’s world-class comportment.

Targeting 550 horsepower (410 kW) and 550 lb.-ft. of torque (745 Nm) – final SAE certified power levels will be available in early April 2008 – the CTS-V’s new LSA engine will be the most powerful ever offered in Cadillac’s nearly 106-year history. It is based on GM’s legendary small-block V-8 architecture and features an intercooled supercharger system, premium heat-resistant aluminum-alloy cylinder heads and numerous details designed to ensure the LSA makes its power as quietly and smoothly as possible.

“From the very start, engineers were cognizant of the role a high-performance engine plays in supporting the qualities customers expect in a Cadillac,” said Jim Taylor, Cadillac general manager. “The supercharged LSA engine delivers outstanding performance, but maximum power didn’t come at the expense of refinement or quietness.”

To achieve the desired balance between performance and drivability, the LSA was designed with numerous features and components that attenuate noise, including the supercharger. It has a new, four-lobe rotor design that enhances quietness while also optimizing the performance parameters of the engine.

A pair of six-speed transmissions is offered with the LSA: A new, Tremec TR6060 six-speed manual with a dual-disc clutch; and a Hydra-Matic 6L90 six-speed automatic with paddle-shift control – the first automatic offered in the CTS-V. Each transmission is designed to channel the engine’s tremendous power while simultaneously delivering exceptional refinement and smoothness.

Supercharged power and superior refinement
Delivering more than merely milestone power numbers, the LSA engine’s sixth-generation Eaton supercharger enables a broader range of power through the rpm band. This gives the engine great low-end torque and excellent horsepower at higher rpm – the range of the rpm band where a supercharger generally loses its effectiveness.

“The new design of the supercharger’s rotating internal components extends its effective range, giving the engine a wide, flat power band that is usable at all rpm levels,” said Ron Meegan, assistant chief engineer. “Whether at low speeds or on the highway, the feeling of power is instant, strong and sustained.”

An intercooler mounted atop the engine sends the supercharger’s pressurized air through a heat exchanger to lower its temperature before entering the engine’s intake system. The cooler air is denser, helping the engine maximize performance.

Complementing the LSA’s tremendous output is a combination of components and design elements designed to ensure a quiet, refined driving experience. Examples include:

• Balanced, lightweight reciprocating assembly
• Hypereutectic pistons
• Lower-lift, low overlap camshaft
• Center-feed fuel system
• Acoustic engine cover
• Piston oil squirters

The new, four-lobe rotor design of the sixth-generation Eaton supercharger also contributes significantly to the LSA’s quiet performance. In fact, the quiet operation of the supercharger system fooled several onlookers during the CTS-V’s development – onlookers who were convinced that a prototype running at wide-open throttle on Germany’s famed Nürburgring racing circuit couldn’t possibly have a supercharger because there was no audible sound from the drive system.

“The characteristic whine of the supercharger is drastically reduced because of the LSA’s four-lobe rotor design,” said Meegan. “And with the other noise-reduction features used throughout, the sound is virtually eliminated.”

Transmission details
The new TR6060 transmission is based on the proven T56 six-speed used in the previous CTS-V, but upgraded to handle the LSA engine’s substantial increase in torque, as well as improve shift quality, via a dual-disc clutch system.

The twin-disc clutch delivers exceptional clamping power and excellent shift effort, achieved with the use of a pair of smaller-diameter clutch discs that have less inertia than a single, larger-diameter disc. Like the previous CTS-V, a dual-mass flywheel is used, which allows for smooth, chatter-free performance.

When it comes to the new automatic transmission, GM’s Hydra-Matic 6L90 six-speed automatic transmission features steering-wheel- and console-shifter-activated tap up/tap down gear control, as well as driver-selectable modes that deliver different performance characteristics, i.e. shift points, shift firmness, for different driving conditions. Performance Algorithm Shifting is part of the 6L90’s controller programming and provides a performance-oriented shift pattern during sustained high-performance driving, such as at a racetrack.

A twin-plate torque converter clutch is used with the 6L90 transmission to match the torque output of the LSA engine – the first twin-plate configuration used with GM’s 300-mm torque converter. Like the dual-disc clutch of the six-speed manual transmission, the twin-plate converter clutch provides exceptional clamping power.

New, Performance Traction Management technology works with the CTS-V’s engine and transmissions to optimize traction and maximize the performance driving experience.

Sounds like another quality GM vehicle is about to hit the streets. The TR6060 is exciting too. Couple questions though:

* Balanced, lightweight reciprocating assembly
* Hypereutectic pistons Not forged?
* Lower-lift, low overlap camshaft
* Center-feed fuel system
* Acoustic engine cover
* Piston oil squirters What exactly is that?

I can't help as to the pistons...I have no idea. As for the squirters, those are little "oil-guns" that actually squirt the bottom of the pistions with oil. Primarily used for Cooling/Lubrication in a High-Performance engine

[headpunter]

the hypereurectic pistons are a type of forged, so when they fail they shatter instead of becoming a fist sized projectile they break into a hundred little pieces and fall into the oil pan

i dont know about them breaking into many little pieces, and they can be forged or cast (forged is stronger), now what makes a piston hypereurectic is just a special way of mixing the metals. For ex, pistons are made of many different metals (the good ones anyways) one primary component is aluminum for its weight savings and good strength. However aluminum expands greatly when it heats up, this large difference in size at different temps makes a tight tolerance engine impossible. So to reduce the expansion of aluminum we can add other ingredients to the mixture.

Which brings us to "eurectic" which means two elements can be alloyed together, BUT only up to a certain percentage, ie you can only add so much salt to a pot of water before it wont dissolve anymore. So for our case of the pistons and aluminum, we add silicon to the aluminum which reduces the amount of expansion. now only about 12% of this mixture can be silicon before it wont "dissolve" anymore, so special processes are used to force extra silicon into the mixture, bringing it to around 20%, this greatly reduces thermal expansion, which allows us to make tighter tolerance engines. the fact that we have now "super-saturated" the mixture of silicon to aluminum above the "eurectic" point of 12% makes it over or hyper eurectic

hope that helps

Go to wiki for more quick info

And as for the CTS-V, I think its awesome that the car of the year is getting a 'boost' in a few months. This is going to be a good year for GM, with the new Malibu, the CTS, the G8, and the ZR1

[GTAHVIT]

Here are some pics, taken by my boss, of the 2009 CTS V from the Concours. This car was on the 10th tee box and was the first car you see when you enter the show. Basically, from the manufacturers perspective, it got top billing. My boss currently owns a 2007 CTSV with the 400hp LS2. He spent quite a bit of time talking with the Caddy Rep. Making plans to trade up I think.

You all may want to sit down for this.... Cost of this car as it sits...

$62,000.00

Uh the Camaro is looking better and better. Especially if we can get close to this kind of power.

And now for the pics. What a georgeous car. And these guys helped design the Camaro... Gotta love it.

[swazworth]

so.... i have a question...is it possible for the LSA to end up in the" top dawg" (whatever the name is) to be the GT500 smoker??

[GTAHVIT]

That is what a bunch of us are hoping for. But it might make the camaro a little too speeeEEEEEnsive.

Well see.
