The future for Chevrolet high-performance fanatics with an inclination towards racing just got a whole lot brighter than it was way back in the mid-twentieth century when racing was officially a GM dirty word and Chevy racers had to fend for themselves.
The great news is General Motors today opened the doors to the all-new GM Powertrain Performance and Racing Center – a state-of-the-art facility designed to enhance the development processes for the company’s diverse racing engine programs.
The new, 111,420-square-foot facility is connected to GM’s Global Powertrain Engineering Center and is part of a $200-million investment at the Pontiac, Michigan, campus. It relocates the Racing center from Wixom, Michigan, to the Pontiac Powertrain Campus, bringing together under one roof an additional team of nearly 100 engine builders, engineers, and other support staff. The Performance and Racing team is responsible for developing engines for NASCAR, NHRA, IndyCar, IMSA, and other racing series.’
It also leverages the resources at the Global Powertrain Engineering Center, enabling faster and more integrated technology transfer between GM’s racing experience and production-vehicle powertrains.
“We race to win and learn,” said Dan Nicholson, vice president, General Motors Global Powertrain. “This new facility offers unprecedented opportunities to connect our racing engineers and powertrain engineers, integrating their knowledge to give our racers an edge on the track and our customers better vehicles on the road.”
Tasked with complete racing engine design and validation, the Performance and Racing Center’s capabilities include:
* Design release
* Full CNC machining
* Engine build
* Electronics and telematics
* Dyno validation
“Chevrolet earned six manufacturer and five driver championships in 2015, and we are carrying that momentum into 2016,” said Jim Campbell, GM U.S. vice president of Performance Vehicles and Motorsports. “This new center is a valuable tool in developing powertrains with the right combination of performance, durability, and efficiency to help our drivers and teams win races and championships.”
The racing engines under responsibility at the new center include:
NASCAR “R07” – a unique 358ci V-8 engine designed and developed exclusively for NASCAR Sprint Cup racing
IndyCar 2.2L Twin-Turbo V-6 – a technical marvel that uses a pair of high-boost-producing turbochargers to help extract about 700 hp from the small-displacement, direct-injected V-6
NHRA COPO Camaro V-8 engines – racers competing with a new 2016 COPO Camaro in NHRA’s Stock and Super Stock eliminator classes can select from supercharged and naturally aspirated LS- and LT-family engines
Corvette Racing 5.5L V-8 – Based on the production LT engine family, the naturally aspirated and all-aluminum 5.5L V-8 engine is used by the Corvette Racing C7.R team
Cadillac ATSV.R Twin Turbo – A racing engine based on the production model’s 3.6L twin-turbo engine.
Additionally, the high-performance crate engines and crate powertrain systems offered by Chevrolet Performance are developed at the new facility.
A clean-sheet design of the new facility incorporates the latest engine-assembly, engine-testing and calibration equipment. The connected layouts of the engine assembly and testing areas are designed to enhance workflow, making it easier for the eight dedicated performance and racing engine builders to retrieve parts, build engines, and move them to the dyno cells. Collectively, they bring 150 years of engine-building experience.
Facility highlights include:
Engine assembly – There are 10 all-new engine build bays – eight in the Engine Build room and two in the prep area to facilitate quicker transfer to dyno testing and other validation areas. Each 120-square-foot bay has an air-drop for powered tools and access to an overhead crane for easy loading on the build stands. Builders also use specialized tools such as programmable torque wrenches to help ensure consistency with the engines. Additional specialty tools at their disposal include a Cam Doctor for precise camshaft evaluations and a ROMER Arm coordinate measuring machine.
Machining – Engineers and builders also have access to over 30 machining tools, offering complete machining capability for cylinder blocks, cylinder heads, fuel rails, and engine components, comparable to the racing industry’s best racing shops. The equipment roster includes nine CNC machines that can transform designs right into new components – including a new Hurco five-axis machine. The staff also has access to a 3D printer for constructing new or modified components, as well as laser scanners to help ensure the powertrain parts meet the high degree of dimensional accuracy demanded for the rigors of racing.
Engine testing – There are four state-of-the-art AVL engine dynamometer cells dedicated to the Performance and Racing Center:
Two gas-powered engine dynos
A gas-powered driveline dyno
A new electric driveline dyno
The engine dynos are similar to those used to develop GM’s production engines, but rated for the high output of racing engines. The gas and electric driveline dynos are firsts for GM Powertrain’s campus and are used to test axle differentials for NASCAR and IndyCar. The drive input capability for each is more than 1,000 horsepower and approximately 560 lb-ft of torque, while the drive output capability is approximately 885 hp and 2,500 lb-ft of torque.
Calibration – An electronics lab is used for the design, assembly and calibration of custom control systems that drive most of the racing and performance engines. Engineers are also able to make calibration changes in the dyno cells. In fact, the dynos can use telemetry data from the racecars’ control systems to replay an engine’s entire race, which can help with development of new engines and calibration changes for existing ones.
Interactive lobby and meeting space
In addition to its technical development areas, the new Performance and Racing Center also features an airy, modern and connected lobby that celebrates GM’s motorsports legacy, as well as a conference center that accommodates up to 125 people. It can be reserved by racing teams, component suppliers and even enthusiast clubs and organizations seeking a meeting location under the checkered flags of GM’s racing programs.
“Louis Chevrolet established GM’s racing legacy more than a century ago, and every win since then has helped us design and build better vehicles,” said Campbell. “With the new Powertrain Performance and Racing Center, we will advance that legacy with greater competitiveness on the track and stronger technology transfer to production vehicles.”
About GM’s Global Powertrain Engineering Center
Located in Pontiac, GM Powertrain is responsible for all GM vehicle propulsion systems’ design, development, and validation, including engines, transmissions, electrification systems, and fuel cell development. It is the flagship of GM’s global eight powertrain centers, which also include Brazil, Germany, Italy, India, China, Korea, and Australia, which collectively represent $1 billion in investments in recent years.
