General Motors Invests $167 Million in Spring Hill for New Vehicles

General Motors Invests $167 Million in Spring Hill for New Vehicles

From General Motors:

SPRING HILL, Tenn. – General Motors today increased to $350 million planned spending for new vehicles to be produced at its Spring Hill assembly plant. The new investment adds $167 million to a previously announced $183 million pledge and is expected to create or retain about 1,800 jobs.

The new investment is for two projects:

An additional $40 million added to the earlier announced $183 million investment to support a future mid-size vehicle program, bringing the new total investment to $223 million. This program is expected to create or retain approximately 1,000 jobs.

A second mid-size vehicle program with an investment of $127 million that will create or retain approximately 800 jobs.
Timing and product specifications for both programs will be shared closer to start-of-production.

The new programs will add to existing manufacturing operations at the site that include vehicle assembly, stamping, engine and component parts production.

“Today’s announcement recognizes the commitment of Spring Hill employees and leadership,” said Mark Reuss, president, GM North America. “As a team, they draw upon the plant’s unique heritage and dedicated work force to deliver top quality for our customers.”

Located 40 miles south of Nashville, GM Spring Hill Manufacturing operates as a flexible-assembly plant, capable of building a variety of products on a range of platforms. The facility is designed to supplement production for plants being retooled for new products or add production to meet sales spikes in real time.

Chevrolet Equinox production began at the site in the third quarter of 2012 to meet growing consumer demand and support GM’s Canada operations. GM Spring Hill Manufacturing, home to the former Saturn brand from 1990 to 2007, operates as a fully integrated complex.

“I would like to thank General Motors for its confidence that the highly skilled members of UAW Local 1853 can successfully build mid-size vehicles with high quality here at Spring Hill,” said UAW Vice President Joe Ashton, who directs the union’s GM Department. “The hard work and dedication of our members once again proves that we can competitively manufacture vehicles for the future right here in Tennessee.”

General Motors: Cadillac’s Twin-Turbo Kicks Turbo Lag to the Curb

General Motors: Cadillac’s Twin-Turbo Kicks Turbo Lag to the Curb

From General Motors:

DETROIT – Turbocharging increases power and performance with efficiency, but the delay in the delivery of power – known as “turbo lag” – has historically been its key limitation.

That’s about to change.

Cadillac’s first-ever Twin-Turbo, available on the 2014 CTS Vsport midsize luxury sedan and XTS Vsport full-size luxury sedan in the U.S. this fall, kicks turbo lag to the curb with a unique combination of smaller turbochargers, top-mounted throttle body and shorter air pathways.

The Cadillac Twin-Turbo V-6’s patented air flow design, which eliminates circuitous heat-exchanger tubing, makes the most of engine packaging efficiency to improve torque response time over other air flow designs.

Rated at 420 horsepower in the all-new 2014 CTS Vsport and paired with Cadillac’s first eight-speed transmission, the Twin Turbo is one of the most power-dense engines in the midsize luxury sedan segment, rated at an SAE-certified 420 horsepower (313kw) and 430 lb-ft of torque (583 Nm).

Air flow routing volume is reduced by more than 60 percent when compared with a conventional design that features a chassis-mounted heat exchanger. The water-to-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.

“By creating a very short path from the turbos to the throttle body, the compressors are able to draw air directly from the inlet box and send pressurized air through the intercooler immediately,” said Richard Bartlett, Cadillac assistant chief engineer for the 3.6L engine. “This gives the driver a more immediate feeling of power on demand.”

Using two smaller turbochargers rather than a single, larger turbo also helps ensure immediate performance because smaller turbochargers spool up quicker to generate horsepower-building air pressure that is fed into the engine. An integrated charge air cooling system also contributes because the compressors blow through very short pipes up to the intercooler.

The single, centrally located throttle body atop the engine controls the air charge from a pair of turbochargers after the temperature is reduced in the intercooler. This design fosters more immediate torque response and reduces complexity by eliminating the need for a pair of throttle bodies.
Together, smaller turbochargers, top-mounted throttle body and shorter air pathways help sustain peak torque over a broad range – 1,900 to 5,600 rpm – for a confident feeling of power in almost all driving conditions, such as accelerating or overtaking traffic on the highway.

“The Cadillac Twin-Turbo intercooler design builds on our experience with the 6.2L supercharged engine used on the current CTS-V Series,” Bartlett said. “That means more performance for drivers without sacrificing efficiency.”

General Motors: Corvette Stingray Most Efficient Sports Car on the Market

Corvette Stingray Most Efficient Sports Car on the Market

From General Motors:

DETROIT – The 2014 Corvette Stingray will deliver up to an EPA-estimated 17 miles per gallon in the city, and 29 mpg on the highway, making the new Stingray the most fuel efficient sports car on the market as no other car offers more than 455 horsepower and greater than 29 mpg highway.

“The Corvette Stingray establishes the benchmark for modern performance cars by using technologies to deliver more performance and more miles per gallon,” said Tadge Juechter, executive chief engineer for the Corvette. “We expect more and more performance cars will follow Corvette’s example.”

The EPA estimate of 17 city and 29 highway is for the Corvette Stingray equipped with an all-new, seven-speed manual transmission. The estimate reflects an average of fuel economy in both the default “Tour” mode, which delivers 28 mpg highway, and driver-selectable “Eco” mode, which delivers 30 mpg highway. For Stingrays equipped with the seven-speed manual transmission, Eco mode enables Active Fuel Management, which disables four of the cylinders for improved fuel economy during light engine loads.

For Corvette Stingrays equipped with the six-speed automatic, Active Fuel Management is active in all drive modes until the driver engages the manual-shift mode using the steering-wheel paddles. Fuel economy estimates for Corvette Stingrays equipped with the six-speed automatic will be finalized soon.

The highway rating represents an 11-percent increase in fuel economy over the previous Corvette, while the all-new 6.2L LT1 V-8 delivers 455 horsepower, a 6-percent increase over the previous Corvette. The LT1 delivers 460 horsepower with the available dual-mode exhaust.

By comparison, the Porsche 911 Carrera S delivers 400 horsepower, and an EPA-estimated 27 mpg highway.

Sports cars with more than 455 horsepower typically offer significantly lower highway fuel economy estimates than the Corvette Stingray. For example, the Jaguar F-Type S offers 495 hp and 23 mpg highway while the Audi R8 V10 offers 510 hp and 19 mpg highway.

Sports cars that deliver more than 29 mpg highway based on EPA estimates typically deliver significantly less engine output. For example, the Porsche Cayman offers 30 mpg and 275 hp while the BMW Z4 sDrive28 delivers 34 mpg and 241 hp.

The 2014 Corvette Stingray coupe goes on sale this fall, with a convertible following by the end of the year.

GM, Honda to Collaborate on Next-Generation Fuel Cell Technologies

GM, Honda to Collaborate on Next-Generation Fuel Cell Technologies

From General Motors:

NEW YORK – General Motors (NYSE: GM) and Honda (NYSE: HMC) announced today a long-term, definitive master agreement to co-develop next-generation fuel cell system and hydrogen storage technologies, aiming for the 2020 time frame. The collaboration expects to succeed by sharing expertise, economies of scale and common sourcing strategies.

GM and Honda plan to work together with stakeholders to further advance refueling infrastructure, which is critical for the long-term viability and consumer acceptance of fuel cell vehicles.
GM and Honda are acknowledged leaders in fuel cell technology. According to the Clean Energy Patent Growth Index, GM and Honda rank No. 1 and No. 2, respectively, in total fuel cell patents filed between 2002 and 2012, with more than 1,200 between them.

“This collaboration builds upon Honda and GM’s strengths as leaders in hydrogen fuel cell technology,” said Dan Akerson, GM chairman and CEO. “We are convinced this is the best way to develop this important technology, which has the potential to help reduce the dependence on petroleum and establish sustainable mobility.”

Takanobu Ito, president & CEO of Honda Motor Co. Ltd. said: “Among all zero CO2 emission technologies, fuel cell electric vehicles have a definitive advantage with range and refueling time that is as good as conventional gasoline cars. Honda and GM are eager to accelerate the market penetration of this ultimate clean mobility technology, and I am excited to form this collaboration to fuse our leading fuel cell technologies and create an advanced system that will be both more capable and more affordable.”

GM’s Project Driveway program, launched in 2007, has accumulated nearly 3 million miles of real-world driving in a fleet of 119 hydrogen-powered vehicles, more than any other automaker.

Honda began leasing of the Honda FCX in 2002 and has deployed 85 units in the U.S. and Japan, including its successor, the FCX Clarity, which was named the 2009 World Green Car. Honda has delivered these vehicles to the hands of customers in the U.S. and collected valuable data concerning real-world use of fuel cell electric vehicles.

As already announced, Honda plans to launch the successor of FCX Clarity in Japan and the United States in 2015, and then in Europe. GM will announce its fuel cell production plans at a later date.

Fuel cell technology addresses many of the major challenges facing automobiles today – petroleum dependency, emissions, efficiency, range and refueling times. Fuel cell vehicles can operate on renewable hydrogen made from sources like wind and biomass. The only emission from fuel cell vehicles is water vapor. 

Additionally, fuel cell vehicles can have up to 400 miles driving range, can be refueled in as little as three minutes, and the propulsion technology can be used on small, medium, and large vehicles.

General Motors: Iconic Corvette Began 60 Years Ago

Chevy Corvette Celebrates 60 years

From General Motors:

BOWLING GREEN, Ky. – On Sunday, Chevy marked its 60th anniversary of the Corvette, an iconic American sports car. The first Corvette went into production in Flint, Mich. on June 30, 1953. Since then, Corvette has become an American icon that continues to offer the best in today’s technology and performance.
“During the past six decades, the Corvette has been woven into the fabric of American culture, as the sports car of choice for movie stars, musicians and astronauts,” said Chris Perry, vice president, Chevrolet Marketing. “The very best Corvettes represent the state-of-the-art for their eras in terms of design, technology and performance.”

Here are some key facts highlighting 60 years of Corvette history:

• Corvette is the world’s longest-running, continuously produced passenger car. The longest-running vehicle of any type is the Chevrolet Suburban.
• Corvette made its debut as a concept vehicle at the General Motors Autorama in New York City on Jan. 17, 1953. It was such a success that a limited run of 300 production Corvettes began on June 30 of that year.
• All 1953 models were Polo White with a red interior and they were priced at $3,498. In 2006, the third 1953 Corvette produced sold for a record $1.06 million at auction.
• Corvette was exclusively available with an inline six-cylinder engine until 1955. That year, the optional V-8 engine was ordered by 90 percent of buyers. The six-cylinder was dropped in 1956. Corvette has been available exclusively with V-8 power since.  
• Corvette was produced only as a convertible for its first 10 years. The fixed-roof 1963 “split-window” Corvette Sting Ray coupe launched the second-generation Corvette.  Sales doubled and it became a year-round car for drivers in colder climates.
• Approximately 1.56 million Corvettes have been produced since June 30, 1953. The 500,000th Corvette was built in 1977; the 1 millionth was built in 1992, and the 1.5 millionth Corvette rolled off the line in 2009.
• Corvettes have been produced at three facilities: Flint, Mich. (1953); St. Louis, Mo., (1954-1981); and Bowling Green, Ky. (1981-2014). The change from St. Louis to Bowling Green happened during the production year. The first 1981 Corvette was built in St. Louis, and the last 1981 Corvette was built in Bowling Green.
• No 1983 Corvettes were sold to the public. The model year was skipped in preparation for the all-new 1984 Corvette, which launched the C4 generation. Forty-four Corvette prototypes were built as 1983 models. Only one remains, and it is on display at the National Corvette Museum, in Bowling Green, Ky.

General Motors: 2014 Cadillac XTS Packs Twin Turbo Power

2014-Cadillac-XTS-twin-turbo-front-view

From General Motors:

DETROIT – Cadillac will add a new option to its XTS luxury sedan: More power and torque. Starting in August, the all-new Cadillac Twin Turbo V6 will go into production as an optional engine for the 2014 XTS.

The new Cadillac Twin Turbo V6 is also a signature feature of the upcoming all-new 2014 CTS luxury performance sedan. In the XTS, the twin turbo will produce an SAE-certified 410 horsepower (306 kW) and 369 lb-ft of torque (500 Nm), making it one of the most power-dense six-cylinder engines among luxury cars. The engine delivers 105 lb-ft more torque over the standard V-6 from1900 to 5600 rpm, providing seemingly endless torque for vehicle responsiveness.

“The addition of the new Cadillac Twin Turbo expands and elevates the XTS luxury sedan,” said Bob Ferguson, vice president Global Cadillac. “This is a compelling enhancement to what is already one of the most technically advanced sedans in our history.”

In both the CTS and XTS product lines, the twin turbo will be the centerpiece of a new model offering called Vsport. The new Vsport is inspired by and slotted “underneath” Cadillac’s elite high-performance V-Series models. Vsport includes the best-performing technical elements inside the “regular” car line in a single model, headlined by Twin Turbo engine.

The new Cadillac Twin Turbo is a comprehensive upgrade to the 3.6L dual overhead cam V6 that is standard in the XTS in the U.S. market. Almost every component is unique, including:

• All-new cylinder block casting
• 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 producing 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 quietness and smoothness.

The cylinder heads are also unique. 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.

Pricing for the 2014 XTS starts at $45,525, including destination fees, unchanged from 2013, with standard equipment including the 3.6L V6 engine that makes 306 hp, CUE, intelligent brake assist and Magnetic Ride Control. Three option packages are available: Luxury, Premium and Platinum Collections. 

The XTS Vsport model will be offered only in the up-level Premium and Platinum Collections as all-wheel drive.

General Motors: Silverado V6: Best-in-Class Capability, 24 mpg Highway

General Motors Silverado V6 Best-in-Class Capability

From General Motors:

DETROIT – The 2014 Silverado with the all-new 4.3L EcoTec3 V-6 – the most capable standard V-6 in any full-size pickup truck – will also be a segment leader in fuel economy, helping save customers money when they buy and when they drive.

EcoTec3 engine technology enables 2WD Silverados to match Ram HFE’s 18 mpg city, while 4×4 Silverados achieve 17 mpg city, the best of any full-size pickup. EPA highway estimates are highly competitive: 22 mpg for 4×4 versions, and 24 mpg for 2WD models.

Reflecting Silverado’s straightforward approach to performance and fuel economy, these EPA estimates are achieved without expensive add-ons and apply to all three cab configurations, regular cab, double cab, and crew cab.

Silverados equipped with the 4.3L V-6 also will be the most-capable trucks with standard V-6 engines, with the highest available payload rating of 2,108 pounds and the highest available towing rating of 7,200 pounds.

“Budget-conscious customers often buy V-6 pickups to do real work, and the 2014 Silverado with the 4.3L EcoTec3 V-6 will combine unmatched capability and excellent fuel economy with surprising levels of refinement,” said Jeff Luke, executive chief engineer.

“Our V-6 has torque where you need it to get the job done, with 230 lb-ft of torque available at 1,200 rpm, and more torque available from 2,400 to 5,300 rpm than competitive V-6s make at their peak.”

Truck customers now returning to the showroom will find that Silverado’s standard V-6 now offers better performance than many V-8 powered pickups from just a few years ago, with far superior fuel economy.

“The average pickup on the road is more than 11 years old,” said Luke. “Customers driving these trucks with V-8 engines will be amazed at the power and refinement of Silverado’s new EcoTec3 V-6, which has fuel economy some 30 percent better than older V-8s with comparable performance.”

The new V-6 joins the mainstream 5.3L EcoTec3 V-8, with EPA-estimated highway fuel economy of up to 23 mpg, the best estimates of any V-8 pickup, and better than estimates for the Ford EcoBoost turbo V-6 (22 mpg EPA highway for 2wd models).

Seamlessly switches to four-cylinder operation

Silverado’s combination of capability and efficiency results in part from its EcoTec3 engines, which provide the proven power of a large-displacement truck engine when needed, then switch seamlessly to four-cylinder operation under lighter loads.

“In creating the 2014 Silverado 1500, we looked at a wide variety of powertrain configurations, and concluded that purpose-built truck engines could best provide the payload and towing capability that truck customers require with the long-term dependability they expect,” said Luke.

By creating a new trio of EcoTec3 engines for the 2014 Silverado, Chevrolet was able to make the most of the size and performance of each entry:

-The 4.3L V-6 is a rugged and refined standard engine with best-in-class torque, payload and towing.
-The 5.3L V-8, expected to power three out of four Silverados, gives mainstream customers 355 horsepower, with fuel economy better than any V-8 competitor or Ford’s EcoBoost turbo V-6.
-A new 6.2L V-8, available this fall, will be the most powerful engine offered on any light-duty pickup, with an estimated 420 horsepower and 450 lb-ft of torque, and a maximum available towing rating of 12,000 pounds.

All three EcoTec3 engines feature direct fuel injection, Active Fuel Management (cylinder deactivation) and continuously variable valve timing, a combination not found in competitive trucks. The engines also use a compact overhead valve design and weight-saving components such as aluminum blocks and cylinder heads to reduce the mass of the engines for additional energy savings.

General Motors: 2014 Corvette Stingray Cranks Out 460 Horsepower

General Motors: 2014 Corvette Stingray Cranks Out 460 Horsepower

From General Motors:

DETROIT – The 2014 Corvette Stingray’s all-new LT1 6.2L V-8 engine is SAE-certified at 460 horsepower (343 kW) at 6,000 rpm and 465 lb-ft of torque (630 Nm) at 4,600 rpm, with the available performance exhaust system, Chevrolet announced today.

The Stingray is SAE-certified at 455 horsepower (339 kW) and 460 lb-ft (624 Nm) with the standard exhaust system. They are the highest standard power ratings ever for the Corvette, delivered with efficiency that is expected to exceed 26 mpg on the highway.

“The 2014 Corvette Stingray’s LT1 engine is a triumph of advanced technology, delivering more power and torque than ever before with greater efficiency,” said Jordan Lee, Small Block chief engineer.

“The LT1’s performance complements the Corvette’s low mass with a tremendous feeling of power that builds as the rpm climbs. Drivers will experience more power and acceleration than ever before with the standard engine – in fact, its power and torque surpass many uplevel engines offered by competitors.”

At 74 horsepower per liter, the LT1 has greater power density than the C6 Corvette’s LS3 6.2L engine and even the C6 Z06’s racing-derived 7.0L LS7. It also produces comparable torque to the LS7 – up to 4,700 rpm – and its peak torque is within 5 lb-ft of the 7.0L engine. That torque is generated early and sustained across the rpm band, with 316 lb-ft available at only 1,000 rpm and 90 percent of peak torque available from 3,000 rpm to 5,500 rpm – giving the lightweight Corvette Stingray excellent acceleration at all speeds.

Chevrolet estimates the Corvette will run from 0 to 60 mph in less than four seconds.

The new LT1 engine’s high output, and high power density and efficiency are due to several advanced technologies, including direct injection, Active Fuel Management and continuously variable valve timing, which support an advanced combustion system.

Direct injection is a primary contributor to the engine’s combustion efficiency, ensuring a more complete burn of the fuel in the air-fuel mixture. That’s achieved by precisely controlling the mixture motion and fuel injection spray pattern. Direct injection also keeps the combustion chamber cooler, which allows for a higher compression ratio. Emissions are also reduced, particularly cold-start hydrocarbon emissions, which are cut by about 25 percent.

Active Fuel Management, or cylinder deactivation, is a first-ever application on Corvette. It helps save fuel by imperceptibly shutting down half of the engine’s cylinders in light-load driving. Continuously variable valve timing is refined to support the LT1 AFM and direct injection systems to further optimize performance, efficiency and emissions.

These technologies support the all-new, advanced combustion system, which incorporates a new cylinder-head design and a new, sculpted piston design that is an integral contributor to the high-compression, mixture motion parameters enabled by direct injection.

Additional engine features include:

Advanced oiling system with oil-spray piston cooling and available dry-sump oiling
Engine-mounted, camshaft-driven fuel pump to support the direct injection system
Intake manifold with “runners in a box” design that allows for high-efficiency airflow packaged beneath the Corvette’s low hood line
High-flow, four-into-one exhaust manifolds based on the design of the LS7 engine.
Small Block legacy

The 2014 Corvette Stingray’s LT1 engine is the fifth generation of the Small Block engine family, which debuted in the Corvette in 1955. It displaced 4.3L (265 cubic inches) and was rated at 195 horsepower, drawing air and fuel through a four-barrel carburetor. Five years later, Small Block power helped Corvette secure its first victory at the 24 Hours of Le Mans.

In 2012, the Small Block-powered Corvette Racing C6.R beat Ferrari, BMW and Porsche to sweep the drivers’, team, and manufacturer championships in production-based American Le Mans Series GT class. These championships make Corvette Racing the most successful team in ALMS history, with a total of 77 class wins, eight drivers’ championships, and nine manufacturer and team championships since 2001.

The 2014 Corvette Stingray coupe goes on sale this fall, with a convertible following by the end of the year – each sharing an all-new aluminum frame structure and enhanced chassis, as well as completely new exterior and interior designs.
