63-612: GMT 360 is a vehicle platform that was manufactured by General Motors from the 2002 and 2009 model years. Designed primarily for SUVs, the GMT360 architecture served as the third generation of mid-size SUVs produced by GM. Directly succeeding its GMT330 predecessor in the United States, GMT360 vehicles based on the platform were sold with their predecessor in Canada and export markets through 2005. The GMT360 architecture
126-469: A SUV . The Volkswagen A platform -mates such as the sports-oriented Audi TT and the economy-focused Volkswagen Golf also share much of their mechanical components but are visually entirely different. Both the Volkswagen Group and Toyota have had much success building many well-differentiated vehicles from many marques , from the same platforms. One of the least conspicuous recent examples
189-529: A 15% stake in AeroVironment . In 1989, GM acquired half of Saab Automobile 's car operations for $ 600 million. In August 1990, Robert Stempel became CEO of the company, succeeding Roger Smith . GM cut output significantly and suffered losses that year due to the early 1990s recession . In 1990, GM debuted the General Motors EV1 (Impact) concept, a battery electric vehicle , at
252-530: A British producer of high-performance sports cars . In 1987, in conjunction with AeroVironment , GM built the Sunraycer , which won the inaugural World Solar Challenge and was a showcase of advanced technology.

The GM labor force participated in the formation of the United Auto Workers labor union in 1935, and in 1936 the UAW organized the Flint Sit-Down Strike , which initially idled two key plants in Flint, Michigan, and later spread to 6 other plants including those in Janesville, Wisconsin and Fort Wayne, Indiana . In Flint, police attempted to enter
504-477: A greater variety of vehicles from one basic set of engineered components. Pictured below is the Nissan MS platform , where designs including 5-door hatchback, sedan, compact SUV and minivan were built on a common floor panel and many shared functional assemblies such as engine, transmission and chassis components. Many vendors refer to this as product or vehicle architecture . The concept of product architecture
567-450: A long-wheelbase SUV (codenamed GMT370), a retractable-roof wagon/SUV/truck, and a hardtop convertible pickup truck. Originally slated to be replaced by a body-on-frame SUV (codenamed GMT361), the GMT360 chassis was discontinued after 2009 model year and replaced by two unibody-chassis vehicle platforms. The GMT360 was replaced in 2010 by the Theta platform ; the longer-wheelbase GMT370
630-710: A lower cost to consumers. Additionally, economies of scale are increased, as is return on investment. Originally, a "platform" was a literally shared chassis from a previously-engineered vehicle, as in the case for the Citroën 2CV platform chassis used by the Citroën Ami and Citroën Dyane , as well as the Volkswagen Beetle frame under the Volkswagen Karmann Ghia . These two manufacturers made different category of vehicles under using
693-461: A namesake defense vehicles division which produces military vehicles for the United States government and military, the vehicle safety, security, and information services provider OnStar , the auto parts company ACDelco , a namesake financial lending service , and majority ownership in the self-driving cars enterprise Cruise LLC .

Key mechanical components that define an automobile platform include: Platform sharing is a product development method where different products and the brand attached share the same components. The purpose with platform sharing
819-542: A program to develop a lightweight two-stroke diesel engine for possible usage in automobiles. Soon after, GM acquired Electro-Motive Company and the Winton Engine Co. , and in 1941, it expanded EMC's realm to locomotive engine manufacturing. In 1932, GM acquired Packard Electric (not to be confused with the Packard car company, which merged with Studebaker years later). The following year, GM acquired
882-491: A strategy affects the development process and also has an important impact on an automaker's organizational structure. A platform strategy also offers advantages for the globalization process of automobile firms. Because automakers spend the majority of time and money on the development of platforms, platform sharing affords manufacturers the ability to cut costs on research and development by spreading it over several product lines. Manufacturers are then able to offer products at
945-422: A strategy by CEO Roger Smith to derive at least 10% of its annual worldwide revenue from non-automotive sources. GM also intended to have EDS handle its bookkeeping, help computerize factories, and integrate GM's computer systems. The transaction made Ross Perot the largest shareholder of GM; however, disagreements with Roger Smith led the company to buy all shares held by Ross Perot for $ 750 million in 1986. In
1008-505: Is among the most widely rebranded GM platforms in modern history. Alongside its adoption by each GM brand (except Cadillac , Hummer , Pontiac and Saturn ), the SUV platform was additionally marketed by associated brand Isuzu . Following the closure of Oldsmobile after the 2004 model year, its version was adopted by the Buick and Saab brands. The architecture was sold as a five-door SUV,
1071-610: Is known as the N-J-L platform, arguably the most prolific of GM's efforts on one platform. Once more, GM's four lower-level divisions all offered various models on this platform throughout the 1980s and into the 1990s. The 1988 Fiat Tipo was one of the first European cars utilizing a modular platform , also used for the Fiat Tempra . Japanese carmakers have followed the platform sharing practice with Honda 's Acura line, Nissan 's Infiniti brand, and Toyota's Lexus marque, as
1134-569: Is most known for owning and manufacturing four automobile brands: Chevrolet , Buick , GMC , and Cadillac . By total sales, it has continuously been the largest automaker in the United States, and was the largest in the world for 77 years before losing the top spot to Toyota in 2008. General Motors operates manufacturing plants in eight countries. In addition to its four core brands, GM also holds interests in Chinese brands Baojun and Wuling via SAIC-GM-Wuling Automobile . GM further owns
1197-449: Is practiced in the automotive industry to reduce the costs associated with the development of products by basing those products on a smaller number of platforms. This further allows companies to create distinct models from a design perspective on similar underpinnings. A car platform is not to be confused with a platform chassis , although such a chassis can be part of an automobile's design platform, as noted below. A basic definition of
1260-692: Is the Chevy Trailblazer and Chevy SSR ; both use the GMT-360 platform. In automotive design, the top hat is one or more vehicle upper body structures that can share a common platform. The upper body could vary from a crossover to a sedan or coupe thereby creating economies of scale and product differentiation . General Motors General Motors Company ( GM ) is an American multinational automotive manufacturing company headquartered in Detroit , Michigan, United States. The company
1323-441: Is the scheme by which the function of a product is allocated to physical components. The use of a platform strategy provides several benefits: The car platform strategy has become important in new product development and in the innovation process. The finished products have to be responsive to market needs and to demonstrate distinctiveness while – at the same time – they must be developed and produced at low cost. Adopting such

#17327910105071386-407: Is to reduce the cost and have a more efficient product development process. The companies gain on reduced procurement costs by taking advantage of the commonality of the components. However, this also limits their ability to differentiate the products and imposes a risk of losing the tangible uniqueness of the product. The companies have to make a trade-off between reducing their development costs and
1449-625: The Fortune 500 and 50th on the Fortune Global 500 . In 2023, the company was ranked 70th in the Forbes Global 2000 . In 2021, GM announced its intent to end production of vehicles using internal combustion engines by 2035, as part of its plan to achieve carbon neutrality by 2040. By 1900, William C.

1512-848: The Allies of World War II . In 1940, GM's William S. Knudsen served as head of U.S. wartime production for President Franklin Roosevelt , and by 1942, all of GM's production was to support the war. GM's Vauxhall Motors manufactured the Churchill tank series for the Allies, instrumental in the North African campaign . However, its Opel division, based in Germany, supplied the Wehrmacht with vehicles. Politically, Sloan, as head of GM at
1575-522: The Cadillac V8-6-4 variable-cylinder engines. GM sold Frigidaire in 1979. Although Frigidaire had between $ 450 million and $ 500 million in annual revenues, it was losing money. Robert Lee of GM invented the neodymium magnet , which was fabricated by rapid solidification, in 1984. This magnet is commonly used in products like a computer hard disk. The same year, GM acquired Electronic Data Systems for $ 2.5 billion from Ross Perot as part of
1638-520: The General Motors Acceptance Corporation (GMAC), which provides financing to automotive customers, was formed. In 1920, du Pont orchestrated the removal of Durant once again and replaced him with Alfred P. Sloan . At a time when GM was competing heavily with Ford Motor Company , Sloan established annual model changes, making previous years' models "dated" and created a market for used cars . He also implemented
1701-682: The LA Auto Show . It was the first car with zero emissions marketed in the US in over three decades. The Impact was produced as the EV1 for the 1996 model year and was available only via lease from certain dealers in California and Arizona. In 1999–2002, GM ceased production of the vehicles and started to not renew the leases, disappointing many people, allegedly because the program would not be profitable and would cannibalize its existing business. All of
1764-567: The Rapid Motor Vehicle Company of Pontiac, Michigan , and the Reliance Motor Car Company of Detroit, Michigan (predecessors of GMC ) in 1909. Durant, with the board's approval, also tried acquiring Ford Motor Company , but needed an additional $ 2 million. Durant over- leveraged GM in making acquisitions, and was removed by the board of directors in 1910 at the order of the bankers who backed
1827-571: The Volvo S40 . Differences between shared models typically involve styling, including headlights , tail lights, and front and rear fascias . Examples also involve differing engines and drivetrains . In some cases such as the Lexus ES that is a Toyota Camry, "same car, same blueprints, same skeleton off the same assembly line in the same factory", but the Lexus is marketed with premium coffee in

2016-491: The dealership's showroom and reduced greens fees at Pebble Beach Golf Links as part of the higher-priced badge. Platform sharing may be less noticeable now; however, it is still very apparent. Vehicle architectures primarily consist of "under the skin" components, and shared platforms can show up in unusual places, like the Nissan FM platform -mates Nissan 350Z marketed as a sports car and Infiniti FX positioned as
2079-537: The "Art and Color Section" of GM and named Earl as its first director. Earl was the first design executive to be appointed to leadership at a major American corporation. Earl created a system of automobile design that is still practiced today. At the age of 24, Bill Mitchell was recruited by Earl to the design team at GM, and he was later appointed as Chief Designer of Cadillac. After Earl retired in December 1958, Mitchell took over automotive design for GM. Also in 1926
2142-588: The EV1s were eventually returned to General Motors, and except for around 40 which were donated to museums with their electric powertrains deactivated, all were destroyed. The documentary film Who Killed the Electric Car? covered the EV1 story. In November 1992, John F. Smith Jr. became CEO of the company. In 1993, GM sold Lotus Cars to Bugatti . In 1996, in a return to its automotive basics, GM completed
2205-684: The United States. Durant was averse to automobiles, but fellow Flint businessman James H. Whiting , owner of Flint Wagon Works , sold him the Buick Motor Company in 1904. Durant formed the General Motors Company in 1908 as a holding company , borrowing a naming convention from General Electric . GM's first acquisition was Buick , which Durant already owned, then Olds Motor Works on November 12, 1908. Under Durant, GM went on to acquire Cadillac , Elmore , Welch , Cartercar , Oakland (the predecessor of Pontiac ),
2268-452: The company acquired Fisher Body , its supplier of automobile bodies. GM acquired Allison Engine Company and began developing a 1,000 horsepower liquid-cooled aircraft engine in 1929. The same year, GM acquired 80% of Opel , which at that time had a 37.5% market share in Europe, for $ 26 million. It acquired the remaining 20% in 1931. In the late-1920s, Charles Kettering embarked on
2331-480: The company in 1915 after a disagreement with Durant. GM was reincorporated in Detroit in 1916 as General Motors Corporation and became a public company via an initial public offering . By 1917, Chevrolet had become successful enough that Durant, with the backing of Samuel McLaughlin and Pierre S. du Pont , reacquired a controlling interest in GM. The same year, GM acquired Samson Tractor . Chevrolet Motor Company
2394-530: The degree of differentiation of the products. Platform sharing is a practice commonly employed by various brands within a corporate group. The fundamental components of a shared platform typically include the chassis and the drive unit. The extent to which different automobile or motorcycle models utilize the same components can vary, leading to different degrees of structural equality and platform similarity: The remaining vehicle parts are categorised into "head" parts and system parts: Platform sharing facilitates
2457-716: The diesel-hybrid market, the Opel Astra diesel engine hybrid concept vehicle was rolled out in January 2005. Later that year, GM sold its Electro-Motive Diesel locomotive division to private equity firms Berkshire Partners and Greenbriar Equity Group. GM paid $ 2 billion to sever its ties with Fiat in 2005, severing ties with the company due to an increasingly contentious dispute. GM began adding its " Mark of Excellence " emblem on all new vehicles produced and sold in North America in mid-2005. However, after
2520-458: The efficient production and development of vehicles by leveraging common components across different models, thereby reducing costs and enhancing operational efficiency. One of the first car companies to use this product development approach was General Motors in 1908. General Motors used a single chassis for certain class of model across most of its brands like Chevrolet , Buick , Pontiac and Oldsmobile . Later, Chrysler Corporation would do
2583-648: The entry-level luxury models are based on their mainstream lineup. For example, the Lexus ES is essentially an upgraded and rebadged Toyota Camry . After Daimler-Benz merged with Chrysler , Chrysler engineers used several M-B platforms for new models including the Crossfire which was based on the M-B SLK roadster . Other models that share platforms are the European Ford Focus , Mazda 3 , and

2646-482: The first hydrogen fuel cell car ever produced. Though fuel cells have existed since the early 1800s, General Motors was the first to use a fuel cell, supplied by Union Carbide , to power the wheels of a vehicle with a budget of "millions of dollars". In the 1960s, GM was an early proponent of V6 engines , but quickly lost interest as the popularity of muscle cars increased. GM demonstrated gas turbine vehicles powered by kerosene , an area of interest throughout
2709-497: The gasoline was harmful to various biological organisms including humans. Evidence shows that corporate executives understood the health implications of tetraethyllead from the beginning. As an engineer for GM, Midgley also developed chlorofluorocarbons , which have now been banned due to their contribution to climate change . Under the encouragement of GM President Alfred P. Sloan Jr., GM acquired Vauxhall Motors for $ 2.5 million in 1925. The company also acquired an interest in
2772-664: The industry, but abandoned the alternative engine configuration due to the 1973 oil crisis . In partnership with Boeing , GM's Delco Defense Electronics Division designed the Lunar Roving Vehicle , which traversed the surface of the Moon, in 1971. The following year, GM produced the first rear wheel anti-lock braking system for two models: the Toronado and Eldorado. In 1973, the Oldsmobile Toronado
2835-601: The largest seller of horse-drawn vehicles at the time. The first half of the 20th century saw the company grow into an automotive behemoth through acquisitions; going into the second half, the company pursued innovation and new offerings to consumers as well as collaborations with NASA to develop the earliest electric vehicles . The current entity was established in 2009 after the General Motors Chapter 11 reorganization . As of 2024 , General Motors ranks 25th by total revenue out of all American companies on
2898-696: The letter "K" to indicate their shared platform. In later stages, the "K" platform was extended in wheelbase, as well as use for several of the Corporation's different models. In the same decade, Fiat and Saab jointly developed cars using the Type Four platform to compete with the German-dominated European executive car segment. General Motors used similar strategies with its "J" platform that debuted in mid-1981 in four of GM's divisions. Subsequently, GM introduced its "A" bodies for
2961-637: The loans to keep GM in business. The action of the bankers was partially influenced by the Panic of 1910–1911 that followed the earlier enforcement of the Sherman Antitrust Act of 1890 . In 1911, Charles F. Kettering of Dayton Engineering Laboratories Company (DELCO) and Henry M. Leland invented and patented the first electric starter in America. In November 1911, Durant co-founded Chevrolet with race car driver Louis Chevrolet , who left
3024-486: The plant to arrest strikers, leading to violence; in other cities, the plants were shuttered peacefully. The strike was resolved on February 11, 1937, when GM recognized the UAW as the exclusive bargaining representative for its workers and gave workers a 5% raise and permission to speak in the lunchroom. Walter E. Jominy and A.L. Boegehold of GM invented the Jominy end-quench test for hardenability of carbon steel in 1937,
3087-528: The pricing strategy used by car companies today. The pricing strategy had Chevrolet , Pontiac , Oldsmobile , Buick , and Cadillac priced from least expensive to most, respectively. In 1921, Thomas Midgley Jr. , an engineer for GM, discovered tetraethyllead (leaded gasoline) as an antiknock agent, and GM patented the compound because ethanol could not be patented. This led to the development of higher compression engines resulting in more power and efficiency. The public later realized that lead contained in
3150-487: The reorganization in 2009, the company no longer added the logo, saying that emphasis on its four core divisions would downplay the GM logo. In 2005, Edward T. Welburn was promoted to the newly created position of vice president, GM Global Design, making him the first African American to lead a global automotive design organization and the highest-ranking African American in the US motor industry at that time. On July 1, 2016, he retired from General Motors after 44 years. He
3213-663: The same chassis design at different years though the primary vehicle was still in production. In the United States, platform sharing has been a common practice since the 1960s. This was when GM used the same platform in the development of the Pontiac LeMans , the Buick Skylark , the Chevrolet Chevelle , and the Oldsmobile Cutlass . In the 1980s, Chrysler 's K-cars all wore a badge with
SECTION 50
#17327910105073276-548: The same for Plymouth , DeSoto and Dodge cars. Ford followed the same principle for Ford and Mercury in US markets. The chassis unit was common with many shared mechanical components while the exterior styling and interior trims were designed according to its individual brand and category. In recent years for monocoque chassis, platform-sharing combined with advanced and flexible-manufacturing technology enabled automakers to sharply reduce product development and changeover times, while modular design and assembly allow building
3339-459: The same four divisions using the same tread width/wheelbase of the "X" body platform, but with larger bodywork to make the cars seem larger, and with larger trunk compartments. They were popular through the 1980s, primarily. Even Cadillac started offering a "J" body model called the Cimarron , a much gussied-up version of the other four brands' platform siblings. A similar strategy applied to what
3402-504: The time, was an ardent opponent of the New Deal , which bolstered labor unions and public transport . Sloan admired and supported Adolf Hitler . Nazi armaments chief Albert Speer allegedly said in 1977 that Hitler "would never have considered invading Poland" without synthetic fuel technology provided by General Motors. GM was compensated $ 32 million by the U.S. government because its German factories were bombed by U.S. forces during
3465-518: The war. Effective January 28, 1953, Charles Erwin Wilson , then GM president, was named by Dwight D. Eisenhower as United States Secretary of Defense . In December 1953, GM acquired Euclid Trucks , a manufacturer of heavy equipment for earthmoving , including dump trucks , loaders and wheel tractor-scrapers , which later spawned the Terex brand. Alfred P. Sloan retired as chairman and

Sloan for $ 45 million, and the McLaughlin Motor Car Company , founded by R. S. McLaughlin , became General Motors of Canada Limited. In 1919, GM acquired Guardian Frigerator Company , part-owned by Durant, which was renamed Frigidaire . Also in 1919,
3591-560: Was eventually discontinued in 2004, seven years after it had become the first American car brand to turn 100. In May 2004, GM delivered the first full-sized pickup truck hybrid vehicles , the 1/2-ton Chevrolet Silverado / GMC Sierra trucks. These mild hybrids did not use electrical energy for propulsion, like GM's later designs. Later, the company debuted another hybrid technology, co-developed with DaimlerChrysler and BMW , in diesel-electric hybrid powertrain manufactured by Allison Transmission for transit buses. Continuing to target
3654-566: Was replaced by Michael Simcoe . In 2006, GM introduced a bright yellow fuel cap on its vehicles to remind drivers that cars can operate using E85 ethanol fuel . They also introduced another hybrid vehicle that year, the Saturn Vue Green Line . In 2008, General Motors committed to engineering half of its manufacturing plants to be landfill-free by recycling or reusing waste in the manufacturing process. Continuing their environmental-conscious development, GM started to offer
3717-438: Was replaced by three-row Lambda platform vehicles (which also replaced all GM minivans). The last GMT360 vehicles were assembled on December 23, 2008. The first GM SUV platform not derived from pickup trucks, GMT360 retained body-on-frame construction with fully boxed hydroformed frame rails, A 113-inch wheelbase was used, with GMT 370 released as a long-wheelbase variant (using a 129-inch wheelbase). Rear-wheel drive
3780-491: Was standard, with part-time four-wheel drive and all-wheel drive as options. The platform used double wishbone independent suspension in front, with a 5-link solid rear axle ; auto-leveling air suspension was offered as an option for some versions. Originally developed for the Atlas series of inline engines, in 2003, a 5.3L V8 was introduced as an option, with a 6.0L V8 becoming an option in 2006. The 6.0L engine (RPO LS2)
3843-608: Was succeeded by Albert Bradley in April 1956. In 1962, GM introduced the first ever turbocharged production car in the world in the Oldsmobile Cutlass Turbo-Jetfire. Two years later, the company introduced its " Mark of Excellence " logo and trademark at the 1964 New York World's Fair . The company used the mark as their main corporate identifier until 2021. GM released the Electrovan in 1966,
