    Staff Writer - CheersandGears.com

    March 18, 2013

    The new Cadillac CTS will be introduced next week at the New York Auto Show, but the brand decided to announce the engine lineup for it this week.

    The big news for the CTS is the introduction of the twin-turbo 3.6-liter V6 good for 420 horsepower and 430 pound-feet. That is mated to an eight-speed automatic transmission. This combination runs to 60 MPH in 4.6 seconds, a top speed of 170 MPH, and returns an estimated MPG of 17 City/25 Highway.

    “The new Cadillac Twin-Turbo brings a new dimension of technologically advanced performance to the all-new 2014 Cadillac CTS sedan,” said David Leone, executive chief engineer. “Delivering power and sophistication, it marks another large step forward in the product-driven expansion of Cadillac.”

    This engine will also be available in the 2014 XTS.

    Other engines for the 2014 CTS will include the 2.0L turbo-four making 272 horsepower and 295 pound-feet of torque, and the 3.6L V6 with 321 horsepower and 275 pound-feet of torque.

    Cadillac Twin-Turbo Debuts in All-New 2014 CTS Sedan

    2013-03-18

    • 420 horsepower (313 kW) / 430 lb-ft of torque (583 Nm) – SAE certified
    • Most power-dense six-cylinder in segment at 118 hp/liter
    • Cadillac’s first twin-turbo engine and eight-speed automatic transmission

    DETROIT – Cadillac today announced details of a new Twin-Turbo V-6 engine and eight-speed transmission – firsts for the brand and signature features of the all-new 2014 Cadillac CTS midsize luxury sedan debuting next week at the New York Auto Show.

    The Cadillac Twin-Turbo V-6 is the most power-dense six-cylinder engine in the midsize luxury segment – a 3.6L with 118 horsepower per liter (88 kW/liter) – and the eight-speed automatic enhances fuel economy and acceleration over a six-speed automatic.

    “The new Cadillac Twin-Turbo brings a new dimension of technologically advanced performance to the all-new 2014 Cadillac CTS sedan,” said David Leone, executive chief engineer. “Delivering power and sophistication, it marks another large step forward in the product-driven expansion of Cadillac.”

    Rated at an SAE-certified 420 horsepower (313 kW) and 430 lb.-ft. of torque (583 Nm), it is the most powerful V-6 ever from General Motors. It also has 15 percent greater power density than BMW 535i’s turbocharged 3.0L six, which is rated at 300 horsepower (223 kW), for a ratio of 100 horsepower per liter (74 kW/liter) – and even the BMW 550i’s TwinPower 4.4L V-8, rated at 400 horsepower (298 kW), or 91 horsepower per liter (68 kW/liter). Power density is a measure of efficiency for an engine’s size.

    A pair of smaller turbochargers and an efficient charge air cooler help provide more immediate power delivery. Additionally, approximately 90 percent of the 3.6L Twin-Turbo’s peak torque is available from 2,500 rpm to 5,500 rpm, giving the engine a broad torque curve that customers will feel as strong, willing power in almost all driving conditions, such as accelerating or overtaking traffic on the highway.

    Those features help the new CTS sedan reach 60 mph from a standstill in an estimated 4.6 seconds and achieve an estimated top speed of 170 mph (274 kph).

    The new Cadillac Twin-Turbo will expand the performance envelope of the upcoming 2014 CTS midsize luxury sedan, launching this fall in the United States. The engine will also will be offered in the 2014 XTS large luxury sedan this fall.

    The new engine is a comprehensive upgrade on the 60-degree, 3.6L DOHC V-6 offered in today’s SRX, XTS and ATS. However, almost every component is unique. New features include:

    • All-new cylinder block casting
    • All-new cylinder head castings
    • Strengthened connecting rods
    • Machined, domed aluminum pistons with top steel ring carrier for greater strength
    • 10.2:1 compression ratio
    • Patented, integrated charge air cooler system with low-volume air ducts
    • Two turbochargers produce more than 12 pounds of boost (80 kPa)
    • Vacuum-actuated wastegates with electronic control valves
    • All-new direct injection fuel system
    • Tuned air inlet and outlet resonators, aluminum cam covers and other features that contribute to exceptional quietness and smoothness.

    The 2014 CTS sedan will also feature the naturally aspirated 3.6L V-6 rated at 321 horsepower, as well as a 2.0L turbocharged engine rated at an estimated 272 horsepower.

    Proven foundation, new features

    Because the Cadillac Twin-Turbo is based on the same architecture as the existing naturally aspirated 3.6L V-6, it benefits from many proven technologies including dual-overhead camshafts, variable valve timing and direct injection. Key features also include:

    • A durable forged steel crankshaft that contributes to greater high-rpm smoothness
    • A friction-reducing polymer coating on the piston skirts, as well as fully floating wrist pins that help reduce friction
    • 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.

    The cylinder block casting is unique to the turbocharged engine with cast-in provisions for turbocharger coolant and oil connections, as well as positive crankcase ventilation passages. It uses nodular iron main bearing caps for greater strength to manage the higher cylinder pressures that come with turbocharging.

    The cylinder heads are also unique to the Cadillac Twin-Turbo. They feature a high-tumble intake port design that enhances the motion of the air charge for a more-efficient burn when it is mixed with the direct-injected fuel and ignited in the combustion chamber. The topology of the pistons, which feature centrally located dishes to direct the fuel spray from the injectors, is an integral design element of the chamber design, as the piston heads become part of the combustion chamber with direct injection.

    “The high-tumble heads were developed with advanced modeling programs that helped us determine the optimal design in less time and with less trial and error,” said Richard Bartlett, assistant chief engineer for the 3.6L engine. “Literally hundreds of simulations were performed to optimize the port flow, injector spray angle and pattern, and piston topology to produce a highly efficient yet powerful combustion chamber.”

    Large, 38.3-mm intake valves and 30.6-mm sodium-filled exhaust valves enable the engine to process tremendous airflow. In some conditions, the continuously variable valve timing system enables overlap conditions – when the intake and exhaust valves in a combustion chamber are briefly open at the same time – to promote airflow scavenging that helps spool the turbochargers quicker for faster boost production.

    Hardened AR20 valve seat material on the exhaust side is used for its temperature robustness, while the heads are sealed to the block with multilayer-steel gaskets designed for the pressure of the turbocharging system.

    As with the naturally aspirated 3.6L, the heads feature integral exhaust manifolds, although upper and lower water jackets were added to the heads to provide uniform temperature distribution and optimal heat rejection. On top of the heads, new aluminum cam covers enhance quietness and are designed with greater positive crankcase ventilation volume to support the turbo system.

    Integrated charge air cooling

    Another unique feature of the Cadillac Twin-Turbo is its efficient manner of processing the pressurized air charge through the cylinder heads and into the combustion chambers. A single, centrally located throttle body atop the engine controls the air charge from both turbochargers after the temperature is reduced in the intercooler. This efficient design fosters more immediate torque response, for a greater feeling of power on demand, and reduces complexity by eliminating the need for a pair of throttle bodies.

    Using a pair of smaller turbochargers rather than a single, larger turbo also helps ensure immediate performance, because smaller turbochargers spool up – achieve boost-producing turbine speed – quicker to generate horsepower-building air pressure that is fed into the engine. The Cadillac Twin-Turbo’s integrated charge air cooling system also contributes to its immediate response, because the compressors blow through very short pipes up to the intercooler.

    With no circuitous heat-exchanger tubing, there is essentially no lag with the response of the turbochargers. In fact, airflow routing volume is reduced by 60 percent when compared with a conventional design that features a remotely mounted heat exchanger.

    “It is a very short path from the turbos to the throttle body,” said Bartlett. “The compressors draw their air directly from the inlet box and send their pressurized air through the intercooler basically immediately, giving the new CTS a tremendous feeling of power on demand.”

    The charge-cooling heat exchangers lower the air charge temperature by more than 130 degrees F (74 C), packing the combustion chambers with cooler, denser air for greater power. The twin-brick configuration of the heat exchangers is similar in design and function to the 6.2L supercharged “LSA” engine used on the current CTS-V Series.

    “The LSA engine showed us the efficiencies of mounting the intercooler on top of the engine, especially when it came to packaging and maintaining a short, unobstructed path for the air charge,” said Bartlett. “It’s efficient and effective – and we wanted to build on that experience.”

    The air cooler system achieves more than 80 percent cooling efficiency with only about 1 psi (7 kPa) flow restriction at peak power, for fast torque production.

    Vacuum-activated wastegates

    Unique vacuum-actuated wastegates – one per turbocharger – and electronic vacuum-actuated recirculation valves are used with the 3.6L Twin-Turbo for better management of the engine’s boost pressure and subsequent torque response for smoother, more consistent performance across the rpm band.

    A wastegate is used to regulate the boost pressure of the engine. It provides a method to bypass the exhaust flow from the turbo’s turbine wheel, which can be reintroduced into the exhaust stream – via a bypass tube – to maintain optimal turbine speed across the rpm band. Conventional wastegates are pressure-activated, allowing control of the actuator.

    The Cadillac Twin-Turbo’s vacuum-activated wastegate valves provide more consistent boost control, particularly at lower rpm, to enhance low-rpm torque, for a greater feeling of power at low speeds. They are independently controlled on each engine bank to balance the compressors’ output to achieve more precise boost pressure response.

    The wastegates also work in concert with the recirculation valves to eliminate co-surge from the turbos – a condition that can result in dynamic flow reversal, such as the moment immediately after the throttle closes. This overall system integration contributes to the engine’s smoother, more consistent feeling of performance.

    In addition to the vacuum-actuated wastegates and recirculation valves, the engine employs dual mass air flow sensors and an integral inlet air temperature/humidity sensor, a dual-compressor inlet pressure sensor and dual manifold pressure sensors.

    Eight speeds, no waiting

    The Cadillac Twin-Turbo is paired with a high-performance, paddle-shift eight-speed automatic transmission that offers efficiency and performance advantages over a six-speed transmission – including 1.5-percent greater fuel economy.

    The new paddle-shift eight-speed delivers smooth, quick shift performance – as quick as 0.3-second on wide-open-throttle upshifts – with the quietness, smoothness and refinement Cadillac customers expect. Smaller gear steps – closer ratios – support world-class performance, with quicker, more imperceptible shifting.

    The wide, 6.71 gear spread of the transmission enables the CTS to deliver strong performance at all rpm levels, while achieving good fuel economy on the highway. A “tall,” 0.69-ratio eighth-gear also helps maintain a low engine speed of approximately 1,800 rpm at 70 mph – about 200 rpm lower than a six-speed – which not only enhances efficiency but contributes to a quieter driving experience.

    Complete electronic control of the transmission enables it to select the best gear for the driving conditions, allowing the transmission to “skip” one or more gears, if appropriate, when up-shifting or down-shifting. In manual mode, torque converter lockup is used in gears two through eight to balance performance and efficiency, while preserving the maximum torque multiplication in first gear for optimal launch performance

    The CTS development team tailored the transmission for the high torque output of Cadillac 3.6L Twin-Turbo, which included stronger gear sets and a greater number of clutch plates. The team also wove in driver-selectable performance features enable the transmission to hold lower gears during certain performance-driving situations, for a more connected and responsive driving experience with the new turbocharged engine.

    Paddle-shift control enables the driver manual control of the gear changes, for the ultimate feeling of control of the turbocharged CTS.

    No Cubical, this engine is a Caddy Engine.

    Camaro can have a twin scroll single turbo v6 of it's own marketing brand.

    We need to build the speciality of each brand and stop watering it down. The last thing we want to hear is people saying "There is the new XTS or CTS with that Chevy Engine.

    OK.

    This engine essentially produces the same HP/TQ/MPG as an NA V8 of medium tune. But it adds a great deal of complexity and expense.

    Is there a gain here?

    I'm not trying to rain on this engine's parade, it is a potent package, but I just don't see much advantage to it after all of the effort put into it.

    It's for a Cadillac, so complexity and expense is a necessity.... it fits better w/ the market niche than an NA pushrod v8 would....BMW was a twin turbo DOHC 6, the M-B E-class is getting one, Audi has a turbo V6 in the A6.

    Nice. The 420-hp twin-turbocharged V8 in the Audi S6 actually gets better MPG than these figures from Cadillac, but this V6 is likely to be much less expensive than competitive forced induction V8s of similar performance.

    I read them.

    No significant differences as compared to an LS3 in a Camaro - except complexity and price.

    The numbers are a wash otherwise.

    Yes and also what the people in this segment want and buy.

    You can force on people what they need or you can give them what they want.

    Like I said in the other tread people in this segment perceived value. Often more technical and the more turbo's and cams the better they like it.

    Camino you have to remember this is not a muscle car segment and the people here are not hung up on cylinder counts but they are hung up on technology and advanced systems. It is kind of like NASCAR vs. F1. Both are fast and NASCAR is as fast and is cheaper but many love the technology and the strategy of F1 when they can keep the tires on the car.

    If Cadillac wants to make inroads into Europe they need to offer what they want over there and people here will still by it because it will be a sweet engine. I am willing to bet the torque curve is flatter and wider than the LT1.

    Either way the CTS standard car is nearly as good as the present V in performance. Make one ponder what they have cooked up for the V. All I know is it will have to be AWD if they want it to hook up.

    The E63 is now turning 3.5 sec 0-60 times and I expect Cadillac may be able to match that with the V.

    As good as pushrods are any car sold outside the states will need to give the global markets what they want. I would not be surprised to see some Euro companies look at the push rod again to gain lower hoods. Some showed envy at the Vette. If they enter the market again it will play into GM's hands as they are already there. GM should also do a better job of marketing the V8 to. Too many have no clue how advanced the new LT is.

    By the way this engine sounds great on the dyno.

    Well, I guess my takeaway from this is that this engine is for those with more money than brains.

    I would have been far more impressed if the engine delivered dramatic fuel economy while maintaining the same performance levels (or even a bit less).

    As is, I see no real advantage at all.

    Camino they look down on your taste too so I guess it is a fair fight.

    The fact is there are a lot of different taste and GM is address more than just yours. There is no right or wrong as long as it sells more cars in more markets.

    I would not diss this engine too much till you drive it. I suspect based on the Turbo 4 it should be a pretty amazing engine and the torque will be in lower and higher than the old 428 HO Pontiac I used to drive.

    You will still get your V8 in the V so just hang on there will be a flavor for everyone.

    C'mon guys, this engine simply doesn't deliver what it should: near V8 performance, with V6 fuel economy.

    I'm not talking about taste, or cylinder count, or flavor, or even what I like or don't like. I'm looking at the numbers, and without gains in fuel economy, they just don't offer much.

    I'm sure I'd enjoy driving a car with this engine, it is quite potent, but what a roundabout way to get to that result!

    It ought to be beyond simple parity with an LS3 - it ought to blow it out of the water.

    Did you read the article? This is clearly V8 performance...

    good for 420 horsepower and 430 pound-feet. That is mated to an

    eight-speed automatic transmission. This combination runs to 60 MPH in

    4.6 seconds, a top speed of 170 MPH

    The fuel econ numbers will likely be class competitive w/ similar models from the German trio... this isn't an engine for a Malibu...premium market buyers aren't as hung up on fuel economy numbers as economy car buyers are.

    the advantage is that Cadillac will be putting an engine in the car people want in cadillac, not one perceived to be a redneck engine or a truck engine.

    I know myself, I would prefer the twin turbo v6. I would not want a v8 in my CTS.

    this engine will go in a bunch of GM stuff also. I'd like to see it in the Corvette and Camaro.

    The marketers need the product to have attributes they can market, not to have to sell concepts that are not much in favor in the buying group's minds.

    60 degree design, two less expensive pistons, shorter and less expensive crankshaft.........

    engine cover is sort of bland.

    I gave it its due on power - the engine has it in spades.

    To Camino's point, you know what would be great to see?

    Some numbers with the LT1 mated with the 8AT. Then we could see which configuration was superior, performance- and economy-wise. Unfortunately, we won't see that until the next Camaro comes out, so we have to wait.

    Let's clarify something: I am not calling for this car to have a V8 - it should not. I am also not calling for more power - it has more than enough.

    In all honesty, I am simply calling for better results overall. My thinking here is that this engine has leaned too far to the performance side and ignored fuel economy.

    This is V-level performance that should have been toned down in favor of MPG gains.

    The V will have to be a lesson in overkill to slot above this engine, and I see that as a mistake.

    Ehh, you young-in's and yur newfangled turbochargers and fuel injection. Back in my day we had carburetors and injections implied a trip to the doctor. We had to crank the engine by hand, none of this motorized starter tomfoolery.

    Don't be foolish, the numbers aren't there.

      The long-delayed Cadillac Super Cruise system will be arriving as an option for the 2018 CT6 this fall. Described as "the industry’s first true hands-free driving technology for the highway,"(Tesla would argue otherwise) Super Cruise combines the driver assistance features currently on the CT6, along with a driver attention system and LiDAR-based mapping data.
      Unlike other systems that monitor forces on the steering wheel to see if the driver is paying attention, Super Cruise uses a camera mounted on the steering column to monitor a driver's head position and movement. If it detects the driver has turned their head away from the road, the system will issue an alert to have the driver bring their eyes back to the road via a light bar on the steering wheel and then the safety alert system. If the driver fails to do this, Super Cruise will bring the car to a stop and call OnStar “if necessary.”
      As for the "LiDAR-based mapping data", this scan of limited-access highways in the U.S. and Canada is paired with an improved GPS system, real-time cameras, and sensors to determine whether or not the system can come on, along with keeping the vehicle on the road.
      “American drivers travel twice as many miles on urban and suburban highways as they do on rural roads. Super Cruise™ allows hands-free driving and operates only within the environment where it has the most benefit. While it is technically possible for the technology to drive hands-free on other kinds of streets and roads, we feel strongly that this targeted approach is the best to build consumer and regulatory confidence and enthusiasm for advanced mobility,” said Barry Walkup, chief engineer for the system.

      GM Was the Fastest Growing Automaker in March, Driven by Chevrolet and Buick
      Strong Retail Share Gain for the First Quarter DETROIT — General Motors (NYSE: GM), which grew its retail sales faster than any other full-line automaker in 2016, outpaced the industry once again in March. The company also gained retail share in the first quarter of 2017.
      “The economy is strong and we see more growth ahead for our brands,” said Kurt McNeil, U.S. vice president of sales operations. “More people are working, consumer confidence is at a 16-year high, fuel prices are low and Chevrolet, Buick, GMC and Cadillac have a wave of new crossovers to compete in the industry’s biggest and hottest segments.”
      At Buick, crossovers are expected to account for more than 75 percent of retail deliveries in 2017, up from 66 percent in 2016, driven by the Encore, Envision and Enclave. GMC, which has the highest average transaction prices (ATPs) of any non-luxury brand, will launch the all-new 2018 Terrain in late summer, complementing the redesigned Acadia that went on sale in late summer 2016. Cadillac will benefit from a full year of production of the new XT5 crossover, which is now the second best-selling vehicle in its segment. Chevrolet, which grew retail market share in 2015 and was the industry’s fastest-growing brand in 2016, is particularly well positioned. Chevrolet had its best March and first quarter retail sales since 2007.
      “Chevrolet will have the industry’s broadest and freshest lineup of utility vehicles led by the all-new 2018 Equinox and Traverse, plus we have a unique three-truck pickup strategy and a dominant position in large SUVs,” McNeil said. “We also have a first-mover advantage in many segments. It will be years before key competitors are able to launch rivals to the Chevrolet Bolt EV, Colorado and Trax.”
      Highlights (vs. 2016)
      First Quarter Overview
      GM’s retail sales were 546,838 units, up 1.9 percent, and retail market share was up 0.2 percentage points to an estimated 16.8 percent. The gains were primarily driven by crossovers, which were up 21 percent. Truck deliveries were up half a percentage point. Chevrolet increased its first quarter retail share by an estimated 0.1 percentage point, as did GMC. Commercial deliveries were up 4 percent, and daily rental deliveries were down 8 percent, or about 6,000 units. Total fleet sales were down 3 percent. Total sales were 689,521 units, up 1 percent, and market share was up an estimated 0.3 percentage points to an estimated 16.7 percent. Average transaction prices were approximately $34,000, in line with last year’s first quarter. March Overview
      Retail sales were 203,113 units, up 5 percent, and market share was up 0.6 percentage points to an estimated 16.1 percent. Chevrolet’s estimated retail market share increased 0.4 percentage points and Buick was up 0.3 percentage points. Total sales were 256,224 units, up 2 percent, and market share was up an estimated 0.4 percentage points to 15.9 percent. Commercial deliveries were up 3 percent driven by a 67 percent increase in Malibu deliveries and strong pickup and large van sales. Daily rental sales down 18 percent, or more than 5,100 units. Fleet sales were down 9 percent. Brand Highlights (vs. 2016)
      Chevrolet Crossovers
      On a retail basis in March, the Trax was up 51 percent, the Equinox was up 26 percent and the Traverse was up 24 percent. For the quarter, Trax retail sales were up 54 percent, the Equinox was up 16 percent and the Traverse was up 7 percent.  Bolt EV sales in the quarter were 3,092 units, with limited availability. The days to turn is exceptionally low at 14 days. Chevrolet Trucks
      Chevrolet had its best first quarter truck sales since 2008, up 6 percent. Key drivers were the Suburban, up 26 percent; the Tahoe, up 11 percent; and strong full-size van sales to small business customers and fleets. Silverado sales were essentially equal to a year ago. Chevrolet retail truck sales in the first quarter were up 2 percent, with the Tahoe up 9 percent, the Colorado up 7 percent and the Suburban up 5 percent. Silverado sales were essentially equal to a year ago. The Tahoe and Suburban had their best March total sales since 2008, and their best first quarter total and retail sales since 2008. The Colorado had its best first quarter retail sales since 2005.   Chevrolet Cars
      Retail deliveries were very strong in March, up 9 percent. The drivers were the Cruze, up 63 percent; the Sonic, up 14 percent; the Spark, up 50 percent; the Volt, up 15 percent; and the Camaro, up 2 percent.  During the quarter, retail car deliveries were down 11 percent, reflecting industry-wide changes in customer demand. However, Cruze retail sales were up 22 percent during the quarter; the Spark was up 37 percent; and the Volt was up 39 percent. The Volt had its best first quarter total and retail sales ever.  Buick Sales
      Buick had its best March retail sales since 2005, with sales up 22 percent. The LaCrosse was up 60 percent on a retail basis in March, the Encore was up 17 percent and Regal was up 7 percent. On a total sales basis, it was Buick’s best March since 2006, with deliveries up 15 percent. First quarter retail deliveries were the highest since 2004, driven by a 29 percent increase in crossover sales. The Encore has posted seven consecutive months of year-over-year sales gains, and it had its best-ever March and first quarter sales. The Envision had its best month since launch. GMC Sales
      Total GMC sales were up 12 percent in March, driven by a 47 percent increase in crossover deliveries. The Acadia, which was redesigned last year, was up 84 percent and the Terrain was up 14 percent. The Yukon XL was up 17 percent. March was the highest-ever month for Denali models, at 29 percent of GMC retail sales. Total GMC sales for the first quarter were the best since 2000, with deliveries up 10 percent. First quarter retail deliveries were up 4 percent, with the Acadia up 30 percent and Sierra HD models up 22 percent. Cadillac Sales
      Cadillac XT5 retail sales in March were 22 percent higher than the outgoing SRX, and ATPs were about 9 percent higher. Cadillac’s ATPs continue to be in the upper echelon of luxury brands at more than $54,000. Full-year Guidance
      We believe strong car-buying fundamentals are reflected in the retail component of the light vehicle SAAR (seasonally-adjusted annual rate), which was 14 million in March, up 0.3 million versus a year ago. The retail SAAR for the first quarter was 14.3 million, up 0.1 million. Ten all-new or recently redesigned crossovers are expected to drive GM’s sales and share higher in 2017. GM’s deliveries to daily rental companies are expected to decline for the third year in a row. The company expects inventory in the second quarter to be lower than the first quarter, in a range around 90 days’ supply. The decline reflects strong sales, lower car production and strategic, launch-related growth in truck and crossover stocks. The company expects to end 2017 at essentially the same inventory levels as 2016 on a days’ supply basis, but with fewer cars and more trucks and crossovers in stock. As expected, incentives were down sharply from February 2017, according to J.D Power PIN estimates. Spending as a percentage of average transaction price (ATP) declined from approximately 14.9 percent to about 13.5 percent. The launches of new crossovers and adjustments to passenger car inventories will help moderate incentive spending going forward.
