The move, backed by a $3.5 million investment and slated for the first quarter of 2014, was part of a consolidation of GM Powertrain engineering sites.
The Performance Build Center has been the source for the 6.2L LS3 V8 engine, which powers the Corvette Grand Sport Coupe manual version; the 7.0L LS7 V8 engine for the Corvette Z06 and the 6.2L Supercharged LS9 engine for the Corvette ZR1.
The move will eventually allow Corvette customers to combine the experience of watching their Corvette being assembled with participating in the build of their vehicle’s high-performance engine. Details on which engines would be available for customer assembly will be announced in the future.
“This is exciting news for the Corvette Assembly Plant and the community of Bowling Green,” said plant manager Dave Tatman. “We host thousands of guests each year, many of whom are here to see their Corvette being built. Bringing the Performance Build Center here simply adds to the thrill of purchasing a Corvette and increases satisfaction for our customers and employees."
In 2011, GM announced a $131 million investment for Bowling Green Assembly, including construction of a new body shop and renovations and upgrades throughout the facility. The improvements support production of the next-generation Corvette, which Chevrolet unveiled on Jan. 13, just before the opening of the North American International Auto Show in Detroit.
“The fine work by the dedicated members of UAW Local 2164 has been proven in building these sports cars. We are pleased with the investment and the resulting transformation of our plant,” stated Joey Cato, UAW Local 2164 shop chairman.
The final economic impact for the Bowling Green community is yet to be determined but will include approximately 20 created or retained jobs, specifically for the Performance Build Center. In the past year, more than 150 jobs have been added to Bowling Green Assembly and more growth is expected as production of the 2014 Corvette begins.
“General Motors is an important key to the continued economic growth of South Central Kentucky,” said Kentucky Gov. Steve Beshear. “This latest investment into the Bowling Green Corvette Assembly plant will not only enhance GM’s commitment to the region but will provide added appeal to the many visitors they host each year. It is beneficial to the local community, the state of Kentucky and all involved.”

CHIEF ENGINEER TADGE JUECHTER TELLS ALL ABOUT THE
DETROIT – When the all-new 2014 Chevrolet Corvette arrives late next year, it will be powered by a technologically advanced, racing-proven 6.2L V-8 delivering an estimated 450 horsepower and helping produce 0-60 times in less than four seconds.
The new Corvette LT1 engine, the first of the Gen 5 family of Small Block engines, combines several advanced technologies, including direct injection, Active Fuel Management and continuously variable valve timing to support an advanced combustion system.
“Our objective for the development of the all-new LT1 was to raise the bar for performance car engines,” said Mary Barra, senior vice president, global product development. “We feel that we have achieved that by delivering a true technological masterpiece that seamlessly integrates a suite of advanced technologies that can only be found on a handful of engines in the world.
“What makes this engine truly special is the advanced combustion system that extracts the full potential of these technologies. The art and science behind that combustion system make the Corvette LT1 one of the most advanced V-8 engines in the world,” said Barra.
Output, performance, and fuel economy numbers will not be finalized until early next year, but the new LT1 engine is expected to deliver:
“The Holy Grail for developing a performance car is delivering greater performance and more power with greater fuel economy and that’s what we’ve achieved,” said Tadge Juechter, Corvette chief engineer. “By leveraging technology, we are able to get more out of every drop of gasoline and because of that we expect the new Corvette will be the most fuel-efficient 450 horsepower car on the market.”
Advanced combustion system optimized with 6 million hours of analysis
“The Corvette LT1 represents the most significant redesign in the Small Block’s nearly 60-year history – building on its legacy to make one of the world’s best engines even better,” said Sam Winegarden, vice president, Global Powertrain Engineering. “More than just great horsepower, the LT1 has been optimized to produce a broader power band. Below 4,000 rpm, the torque of the Corvette LT1 is comparable to that of the legendary, 7.0L LS7 out of the current Corvette Z06. The LT1 is a sweetheart of a power plant and drivers will feel its tremendous torque and power at every notch on the tachometer.”
Increased power and efficiency were made possible by an unprecedented level of analysis, including computational fluid dynamics, to optimize the combustion system, the direct injection fuel system, active fuel management and variable valve timing systems that support it. More than 10 million hours of computational analysis were conducted on the engine program, including 6 million hours (CPU time) dedicated to the advanced combustion system.
Direct injection is all-new to the engine architecture and is a primary contributor to its greater combustion efficiency by ensuring a more complete burn of the fuel in the air-fuel mixture. This is 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 (AFM) – a first-ever application on Corvette – helps save fuel by imperceptibly shutting down half of the engine’s cylinders in light-load driving.
Continuously variable valve timing, which GM pioneered for overhead-valve engines, 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.
The LT1 head features smaller combustion chambers designed to complement the volume of the unique topography of the pistons’ heads. The smaller chamber size and sculpted pistons produce an 11.5:1 compression ratio, while the head features large, straight and rectangular intake ports with a slight twist to enhance mixture motion. This is complemented by a reversal of the intake and exhaust valve positions, as compared to the previous engine design. Also, the spark plug angle and depth have been revised to protrude farther into the chamber, placing the electrode closer to the center of the combustion to support optimal combustion.
The pistons feature unique sculpted topography that was optimized via extensive analysis to precisely direct the fuel spray for a more complete combustion. The contours of the piston heads are machined to ensure dimensional accuracy – essential for precise control of mixture motion and the compression ratio.
Race-proven legacy, state-of-the-art performance
The first Small Block V-8 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, V-8 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 engine requirements for a production car and a race car are remarkably similar,” said Jordan Lee, Small Block chief engineer and program manager. “In both cases, you want an engine that is powerful and efficient, compact and lightweight, and durable. That combination is what made the original Small Block so successful. Today, the introduction of state-of-the-art technologies and engineering makes one of the best performance car engines in the world even better.”
As an example, the new LT1 engine is 40 pounds lighter than a competitor’s twin-turbo 4.4L, DOHC V-8 with similar output. That weight savings not only improves the Corvette’s power-to-weight ratio, but also contributes to a near-perfect 50/50 weight balance for enhanced steering response and handling.
The new LT1 is also four inches shorter in overall height than the competitive DOHC V-8. That also improves handling by lowering the center of gravity while enabling a low hood line – contributing to the Corvette’s iconic profile, as well as ensuring exceptional driver visibility.
The new LT1 is the third engine in the Corvette’s history to be so-named, with previous versions introduced in 1970 (Gen 1) and 1992 (Gen 2). All iterations of the LT1 – and all Small Block engines – have shared a compact design philosophy that fosters greater packaging flexibility in sleek vehicles such as the Corvette.
“The power and efficiency of the Small Block V-8 are hallmarks of Corvette performance,” said Lee. “But, the compact size and great power-to-weight are just as important for the overall driving experience. The all-new LT1 will play a huge role in making the all-new Corvette a world-class sports car, in terms of technology, performance, and refinement.”
Engine features and highlights
All-aluminum block and oil pan: The Gen 5 block was developed with math-based tools and data acquired in GM’s racing programs, providing a light, rigid foundation for an impressively smooth engine. Its deep-skirt design helps maximize strength and minimize vibration. As with the Gen 3 and Gen 4 Small Blocks, the bulkheads accommodate six-bolt, cross-bolted main-bearing caps that limit crank flex and stiffen the engine’s structure. A structural aluminum oil pan further stiffens the powertrain.
The block features nodular iron main bearing caps, which represent a significant upgrade over more conventional powdered metal bearing caps. They are stronger and can better absorb vibrations and other harmonics to help produce smoother, quieter performance.
Compared to the Gen 4 engine, the Gen 5’s cylinder block casting is all-new, but based on the same basic architecture. It was refined and modified to accommodate the mounting of the engine-driven direct injection high-pressure fuel pump. It also incorporates new engine mount attachments, new knock sensor locations, improved sealing and oil-spray piston cooling.
Advanced oiling system, with available dry-sump system: The LT1 oiling system – including oil-spray piston cooling – was also optimized for improved performance. It is driven by a new, variable-displacement oil pump that enables more efficient oil delivery, per the engine’s operating conditions. Its dual-pressure control enables operation at a very efficient oil pressure at lower rpm coordinated with AFM and delivers higher pressure at higher engine speeds to provide a more robust lube system for aggressive engine operation.
Standard oil-spray piston cooling sprays the underside of each piston and the surrounding cylinder wall with an extra layer of cooling oil, via small jets located at the bottom of the cylinders. For optimal efficiency, the oil jets are used only when they are needed the most: at start-up, giving the cylinders extra lubrication that reduces noise, and at higher engine speeds, when the engine load demands, for extra cooling and greater durability.
An available dry-sump oiling system promotes exceptional lubrication system performance during aggressive driving maneuvers and high cornering loads. It includes two stages: a pressure stage and a scavenge stage. The pressure stage includes the new, dual-pressure-control and variable-displacement vane pump.
Dexos semi-synthetic motor oil, with a 5W30 specification, helps reduce friction to further enhance the LT1’s efficiency.
New, tri-lobe camshaft: Compared to the Gen 4 Small Block, the camshaft remains in the same position relative to the crankshaft and is used with a new rear cam bearing, but it features an all-new “tri-lobe” designed lobe which exclusively drives the engine-mounted direct injection high-pressure fuel pump, which powers the direct-injection combustion system. The cam’s specifications include 14mm/13.3mm (0.551/0.524-inch) intake/exhaust lift, 200/207-crank angle degrees intake/exhaust duration at 0.050-inch tappet lift and a 116.5-degree cam angle lobe separation.
New, cam-driven fuel pump: The direct injection system features a very-high-pressure fuel pump, which delivers up to 15Mpa (150 bar). The high-pressure, engine-driven fuel pump is fed by a conventional fuel-tank-mounted pump. The direct injection pump is mounted in the “valley” between cylinder heads – beneath the intake manifold – and is driven by the camshaft at the rear of the engine. This location ensures any noise generated by the pump is muffled by the intake manifold and other insulation in the valley.
PCV-integrated rocker covers: One of the most distinctive features of the new engine is its domed rocker covers, which house the, patent-pending, integrated positive crankcase ventilation (PCV) system that enhances oil economy and oil life, while reducing oil consumption and contributing to low emissions. The rocker covers also hold the direct-mount ignition coils for the coil-near-plug ignition system. Between the individual coil packs, the domed sections of the covers contain baffles that separate oil and air from the crankcase gases – about three times the oil/air separation capability of previous engines.
Intake manifold and throttle body assembly: The LT1’s intake manifold features a “runners in a box” design, wherein individual runners inside the manifold feed a plenum box that allows for excellent, high-efficiency airflow packaged beneath the car’s low hood line.
Acoustic foam is sandwiched between the outside top of the intake manifold and an additional acoustic shell to reduce radiated engine noise, as well as fuel pump noise.
The manifold is paired with an electronically controlled throttle, featuring an 87mm bore diameter and a “contactless” throttle position sensor design that is more durable and enables greater control.
Four-into-one exhaust manifolds: The LT-1 uses a cast version of the “four-into-one” short-header exhaust manifold design used on the Gen 4 LS7 engine. The cast header passages enable consistent exhaust flow into the “wide mouth” collector at the converter.
Cooling system, humidity sensor and more: Additional features and technologies of the Gen 5 Small Block include:
General Motors’ investment in the Gen 5 Small Block will create or retain more than 1,600 jobs in five North American plants, including Tonawanda, New York, which recently received upgrades to support its production.

CORVETTE C7 DEBUT!
BRASELTON, Ga. – Chevrolet today confirmed the seventh-generation Corvette will debut on Sunday evening, Jan. 13, 2013, in Detroit. To start the countdown to 1.13.13, Chevrolet is showing the new Crossed Flags logo for the new 2014 Corvette.
“The all-new, seventh-generation Corvette deserved an all-new emblem,” said Ed Welburn, GM vice president of global design. “The new Crossed Flags design reflects the character of the next Corvette. The flags are much more modern, more technical, and more detailed than before – underscoring the comprehensive redesign of the entire car.”
The new Crossed Flags logo was unveiled at Road Atlanta, where Corvette Racing celebrated a sweep of the 2012 production-based American Le Mans Series GT championships.
Chevrolet secured the manufacturer’s championship; Corvette Racing secured the team championship, and Oliver Gavin and Tommy Milner captured the drivers’ championship with four wins in the nine races preceding Petit Le Mans, the 2012 ALMS season finale.
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 team has also taken seven class victories in the 24 Hours of Le Mans since 2001. Corvette Racing will campaign the C6.R for the 2013 ALMS season. The C7.R is expected to make its racing debut in 2014.
“Winning the ALMS championships with the Corvette C6.R, against prestigious competitors from Ferrari, Porsche, and BMW is the perfect send-off for the sixth-generation Corvette,” said Tadge Juechter, Corvette chief engineer.
“The seventh-generation Corvette will build on that success,” Juechter continued. “With the new Corvette, we set out to build a world-challenging sports car with design, refinement, efficiency and driver engagement that is second to none. The result is a truly all-new Corvette. There are only two carryover parts from the C6 used in the C7 – the cabin air filter and the rear latch for the removable roof panel.”
The Crossed Flags logo has been a hallmark of the Corvette since its 1953 introduction. It has always incorporated a pair of flags, one a racing checkered flag and other featuring the Chevrolet “bowtie” emblem and a French fleur-de-lis. The design has evolved over the years, and has been featured on more than 1.5 million Corvettes built between 1953 and today.
For the seventh-generation Corvette, the Crossed Flags design is a more technical, more angular and more swept appearance – in proportion that symbolizes the new car. It is also a more detailed representation, showing greater depth, color and attention to detail.
More than 100 variations were considered before the final design was selected.
The new Crossed Flags design will be featured on the 2014 Chevrolet Corvette, which will debut for credential media on Sunday, Jan 13, 2013 in Detroit. Chevrolet will offer a limited number of tickets for Corvette enthusiasts, with proceeds benefiting the National Corvette Museum, in Bowling Green, Ky. Interested parties can contact Roc Linkov (firstname.lastname@example.org) for more details.
Over coming weeks, more information and video content about the seventh-generation Corvette will be unlocked on www.one13thirteen.com. Enthusiasts can join the conversation about the next-generation Corvette, as well as keep track of new announcements on Facebook (facebook.com/corvette) and Twitter @Chevrolet(#Corvette). Fans that follow the #one13thirteen hashtag on Twitter can look forward to exclusive updates.
FAST FACT: The first Corvette debuted as a
concept car on Jan. 17, 1953 at the GM Motorama in
New York City. That car originally featured an
emblem with a checkered flag crossed with an
American flag. Because use of the American flag was
prohibited as part of a commercial property, the
logo was changed to the fleur-de-lis/bowtie design
when the Corvette went into production in June 1953.
Z25 60th Anniversary Package and Z27 427 Heritage Package production is running at a strong 27% of all Corvettes being built. These packages will go down in history as some of the most desirable C6’s ever produced. You can never go wrong with a Corvette Convertible with a 427 under the hood!
If your heart pounds to the thrill of a 427 Convertible, get down to your dealer now!
GRAND-AM Road Racing, American Le Mans Series Announce Historic Merger
