CadillacFor other uses, see Cadillac (disambiguation).Cadillac is a brand of luxury automobile, part of the General Motors corporation, produced and mostly sold in the United States; outside of North America, they have been less successful. In the United States, the name became a synonym for "high quality", used in such phrases as "the Cadillac of clocks." This is less prevalent, though still known, in other English-speaking countries (who are more likely to use Rolls-Royce in such phrases). HistoryFoundingCadillac was formed from the Henry Ford Company upon Henry Ford's departure. With the intent of liquidating the firm's assets, Ford's financial backers, William Murphy and Lemuel Bowen called in engineer Henry M. Leland to appraise the plant and equipment prior to selling them. Instead, Leland persuaded them to continue in the automobile business. Henry Ford's departure required a new name, and on August 22, 1902, the company reformed as the Cadillac Automobile Company. The Cadillac automobile was named after the 17th century French explorer Antoine Laumet de La Mothe, sieur de Cadillac, founder of Detroit, Michigan in 1701. Early vehiclesCadillac, 1903 (courtesy the Smithsonian).Their first car was completed in October 1902, the 10 horsepower (7 kW) Cadillac, based on Henry Ford's design was practically identical to the 1903 Ford Model A. Many sources say the first car rolled out of the factory on October 17; in the book Henry Leland - Master of Precision, on p.69, that date is shown to be October 20; yet another reliable source shows car #3 to have been built on October 16. In any case, the new Cadillac was shown at the New York Auto Show the following January, where it impressed the crowds enough to gather over two thousand firm orders. The Cadillac's biggest selling point was precision manufacturing and, therefore, reliability; it was simply a better made vehicle than its competition. In Feb to Mar 1908, three Model K Cadillacs (1907 production) were released from the stock of Frederick Bennett (UK agent for Cadillac) at the Heddon Street showroom in London to compete in the annual Royal Automobile Club's Standardization Test. They were driven 25 miles to the Brooklands race track at Weybridge where they completed another 25 miles (40 km) before being put under lock and key until Monday March 2, 1908 when they were released and disassembled completely. Their 721 component parts were scrambled in one heap; 89 parts requiring extreme accuracy were withdrawn from the heap,locked away at the Brooklands club house and replaced with new parts from the showroom stock. Using only wrenches and screwdrivers the 3 cars were re-assembled and on Friday March 13 they completed a mandatory 500 mile (800 km) run. On completion of the test, one of the cars was placed under lock and key where it remained until the start of the 2000 miles (3200 km) Reliability Trials, several months later. It came out the winner of the R.A.C. Trophy! Parts interchangeability could not have been proven in any other more appropriate way. As a result of these tests, the Cadillac Automobile Company was awarded the Dewar Trophy for 1908 (actual award date was Feb 1909). The Dewar Trophy was an annual award for the most important advancement of the year in the automobile industry. General MotorsCadillac was purchased by the General Motors conglomerate in 1909. Cadillac became General Motors' prestige division, devoted to the production of large luxury vehicles. The Cadillac line was also GM's default marque for "commercial chassis" institutional vehicles, such as ambulances, limousines, hearses, and funeral home flower cars. The latter two of which were custom made by aftermarket manufacturers, GM does not produce any such vehicles on its own. In 1911, Cadillac was the first gasoline internal combustion engine auto to incorporate electric start, as opposed to earlier crank start. Originally marketed as a convenience device for female drivers, the electric starter developed by Charles Kettering was first used on the production models of 1912. Other innovations included the first V8 engine in mass production in 1915; shatter-resistant safety glass in 1926; and the first fully synchronized transmission (with gears "locked" in relation to one another to prevent clashing upon execution of a shift) in 1928. About this time, automobile stylist, Harley Earl, whom Cadillac had recruited in 1926 and who was to head the new Art & Color section starting in January 1928, designed for 1927 a new, smaller "companion" car to the Cadillac which he called the La Salle, after another French explorer, René Robert Cavelier, Sieur de La Salle. That model remained in production until 1940. Pre-World War II Cadillacs were well-built, powerful, mass-produced luxury cars, aimed at an upper class market, below that of such ultra-exclusive marques such as Pierce-Arrow and Duesenberg. In the 1930s, Cadillac added cars with 12- and 16-cylinder engines to their range, many of which were fitted with custom coach-built bodies; these engines were remarkable at the time for their ability to deliver a combination of high power, silky smoothness and quietness. 1932- The year it could have endedIn 1932, after Cadillac suffered from record low sales and charges of discrimination against black customers, Alfred Sloan created a committee to consider the discontinuation of the Cadillac line. At a fateful board meeting, Cadillac president Nicholas Dreystadt gave the GM Board of Directors a 10 minute speech in which he advocated advertising to black consumers so as to increase sales. The Board agreed to give Dreystadt 18 months to produce results. By 1934, Cadillac had regained profitability. By 1940, Cadillac sales had risen 1000% compared to 1934, thus saving Cadillac from extinction. 1934 brought about a revolution in assembly line technology. Henry F. Phillips introduced the Philips screw and driver onto the market. He entered into talks with General Motors and convinced the Cadillac group that his new screws would speed assembly times and therefore increase profits. Cadillac was the first automaker to use the Phillips technology, which was widely adopted in 1940. PostwarPromotional art of the 1947 Cadillac Series 75 SedanPostwar Cadillacs, incorporating the ideas of General Motors styling chief Harley J. Earl, innovated many of the styling features that came to be synonymous with the classic (late 1940s-late 1950s) American automobile, including tailfins and wraparound windshields. Cadillac's first tailfins, inspired by the twin rudders of the Lockheed P-38 Lightning, appeared in 1948; the 1959 Cadillac was the epitome of the tailfin craze, with the most recognizable tailfins of any production automobile. 1960 CadillacAt this point, Bill Mitchell succeeded Harley Earl as styling chief, and his preference for more austere design combined with changing buyer tastes caused the excess to be rapidly toned down, starting in 1960. Nevertheless, Cadillacs retained their tailfins through 1964, and suggestions of them remain in the peaked rear fenders of many models even to this day. The tailfin style gave birth to the enduring vertical-tailight pattern, which is a subtle trademark of the Cadillac line (the opposite of the horizontal tailight pattern which is a likewise subtle trademark of rival Lincoln.) Somewhat surprisingly for a marque with such a strong design heritage, Cadillac has resisted the temptation to produce any "retro" models such as the revived Ford Thunderbird or the VW New Beetle, and has instead pressed ahead with a new design philosophy for the 21st century called "art and science"[1] which it says "incorporates sharp, shear forms and crisp edges - a form vocabulary that expresses bold, high-technology design and invokes the technology used to design it." Low points, and the beginning of a recoveryCadillac suffered from the malaise that set in to the American auto industry in the late 1970s to the late 1980s. There were high points, such as the launch of the Eldorado two-door personal luxury car in 1967, with its simple, elegant design—a far cry from the tail-fin and chrome excesses of the 1950s. However, the 1970s saw vehicles memorable for other types of excess: engine size, for one (the Eldorado featured an 8.2-litre engine at one point), weight, and physical bulk. The build quality also became poorer when measured against German rivals. As with most American brands, Cadillac was forced to downsize its offerings between the 1973 and 1979 fuel crises. Its staple De Ville and Fleetwood lines were downsized for 1977 and again for 1985. It launched a smaller car around the size of the Mercedes-Benz 300, the Seville, based on a Chevrolet Nova platform, which became a success for the marque. Due to gasoline shortages, Cadillac offered a "dieselized" (converted from gasoline use) LF9 350-cubic-inch (5.7L) V8 engine, in its full-size cars from 1979 to 1981. This was a disaster for GM. The engine was notoriously unreliable and smoky. Ironically, GM's other division, Detroit Diesel had had decades of experience building Diesel engines. However, trying to extend its brand further downward to appeal to younger buyers, Cadillac launched in 1981 (for the 1982 model year) the compact Cimarron, a warmed-over Chevrolet Cavalier as a rival to the BMW 3-series. Buyers rejected this model for being too close to the considerably cheaper Chevrolet — unlike the Seville, which did not resemble the Nova or other GM X-cars, the Cimarron was almost indistinguishable from the down-market versions. Buyers also objected to the Cimmaron's four-cylinder engine and low level of standard equipment. Although the motoring press lauded the first Cadillac manual transmission in decades, the automatic's extra cost also rankled buyers. Another low point during the early 1980s was the variable displacement engine, branded the L62 V8-6-4 engine. Introduced in 1981, this 368 in³ (6.0 L) engine sequentially shut down cylinders as demand dropped. Company marketing hailed the engine as cutting-edge technology, but it proved unreliable and was dropped the next year in favor of a family of smaller aluminum V8 engines rushed into production. The 4100 (4.1 liter) V8 engine was used widely in Cadillacs in the late 1980's. This proved to be one of the worst engines ever built. It suffered from coolant leaks, warped intake manifolds and warped heads. The 4100's problems cost Cadillac the loyalty of many customers. The mid-1980s saw Cadillac try to rebuild its image, aware that European and Japanese imports were on a rise, and with Honda launching its American luxury division, Acura. Some new design approaches were tried: the Seville, for instance, had gracefully rounded wheel arches with a hint of chrome. The greatest challenge to the imports was the Cadillac Allante, a convertible designed by Pininfarina of Italy, and built on what was touted as the world's longest production line—with the car's bodies fabricated in Italy and flown by Boeing 747 to the United States to meet their transmission and engine. The car was, sadly, not a commercial success, but today stands out as a modern classic and more than able to hold its own, image-wise, next to its Mercedes-Benz SL rival. The Allante's styling influenced other Cadillacs, especially the Seville, which adopted its sharper, tailored lines. Indeed, Cadillac was so confident of the Seville that it was exported to Europe, but it faced stiff opposition. The Cimarron and Seville models marked a beginning of "smaller" cars for the Cadillac line. Throughout the 1980s, American auto makers downsized most of their models, and the Cadillac was no exception. By the late 80s, the Brougham was the only Cadillac model that retained the style and size of the "big" DeVilles and Fleetwoods of the 70s. It was discontinued after the 1996 model year (the Brougham was rebadged as the Fleetwood Brougham). After GM phased out the GM B platform after 1996, abeit the importation of the European-based Catera, the only equivalent of rear-wheel drive is seen as a sport utility vehicle with the present-day Escalade. The Art & Science eraThe latest incarnation of Cadillac styling - Art & Science (A&S) was previewed with the 1999 Cadillac Evoq concept roadster at that year's Detroit Auto Show. With its crisp lines, hard creases, and sharp corners, the Evoq not only had a striking presence of its own, but also marked a departure from the softer design of previous Cadillacs. Distinctive characteristics of Art & Science design include stacked headlamps, vertical taillamps, angular grille, and creased body lines in addition to alphanumeric model names. The DeVille sedan and 2002 Escalade sport utility were the first executions of the Art & Science design philosophy, though they should be appropriately noted as more transitional vehicles since they combine A&S with the last era of styling and tested the waters for public acceptance. Cadillac's 2003 Cadillac CTS was the first ground-up incarnation of A&S and was an instant hit, partly due to product placements in the cyberpunk Matrix trilogy. Following in its success was the Cadillac SRX sport utility wagon and the Evoq-inspired Cadillac XLR roadster. The 2005 Cadillac STS is the latest in the A&S lineup and will complete the transition between the old school of design and the new. The new Cadillac V-Series was also introduced to provide sporty models based on Cadillac production cars, with very extensive chassis and engine upgrades. A slight evolution of A&S was shown at Detroit's 2003 Auto Show with the Cadillac Sixteen concept, which had a rounded body with crisp A&S features. This version of A&S will probably see itself debuted on models that appeal to more conservative demographics, such as the DeVille's replacement and a possible ultraluxury sedan. The 2005 Presidential Limousine first shown at the second inauguration of President George W. Bush features A&S design cues, and is said to foreshadow the 2006 Cadillac DTS, which is the replacement for the DeVille. In late 2005, Cadillac introduced the new DTS, the replacement of the DeVille, completing the full lineup of A&S models. Also in 2005, General Motors announced the first Cadillac designed exclusively for the European market, a model called the BLS, to be built by Saab in Sweden. Cadillac modelsHistorical and Classic

The 2005 Presidential Limousine first shown at the second inauguration of President George W. They are counter-weighted so as to not slide off the arms under the weight of the remote control. This version of A&S will probably see itself debuted on models that appeal to more conservative demographics, such as the DeVille's replacement and a possible ultraluxury sedan. Remote control bags can be draped over the arm of easy chairs or sofas and used to hold remote controls. A slight evolution of A&S was shown at Detroit's 2003 Auto Show with the Cadillac Sixteen concept, which had a rounded body with crisp A&S features. They come in various shapes, some specifically sized to fit partially under a desk. The new Cadillac V-Series was also introduced to provide sporty models based on Cadillac production cars, with very extensive chassis and engine upgrades. This allows chairs on wheels to roll easily over the carpet and it protects the carpet. The 2005 Cadillac STS is the latest in the A&S lineup and will complete the transition between the old school of design and the new. Chair mats are plastic mats meant to cover carpet. Following in its success was the Cadillac SRX sport utility wagon and the Evoq-inspired Cadillac XLR roadster. Car seats sometimes have built-in and adjustable lumbar supports. Cadillac's 2003 Cadillac CTS was the first ground-up incarnation of A&S and was an instant hit, partly due to product placements in the cyberpunk Matrix trilogy. Obus Forme is a major brand in this category and helped develop this market niche. The DeVille sedan and 2002 Escalade sport utility were the first executions of the Art & Science design philosophy, though they should be appropriately noted as more transitional vehicles since they combine A&S with the last era of styling and tested the waters for public acceptance. Orthopedic backrests provide support for the back. Distinctive characteristics of Art & Science design include stacked headlamps, vertical taillamps, angular grille, and creased body lines in addition to alphanumeric model names. In cars, they may be used to increase the height of the driver. With its crisp lines, hard creases, and sharp corners, the Evoq not only had a striking presence of its own, but also marked a departure from the softer design of previous Cadillacs. Some are decorative. The latest incarnation of Cadillac styling - Art & Science (A&S) was previewed with the 1999 Cadillac Evoq concept roadster at that year's Detroit Auto Show. Chair pads are cushions for chairs. After GM phased out the GM B platform after 1996, abeit the importation of the European-based Catera, the only equivalent of rear-wheel drive is seen as a sport utility vehicle with the present-day Escalade. In the second half of 20th century, some people used custom clear plastic covers for expensive sofas and chairs to protect them. It was discontinued after the 1996 model year (the Brougham was rebadged as the Fleetwood Brougham). Covers for sofas and couches are also available for homes with small children and pets. By the late 80s, the Brougham was the only Cadillac model that retained the style and size of the "big" DeVilles and Fleetwoods of the 70s. The chair covers may come with decorative chair ties, a ribbon to be tied as a bow behind the chair. Throughout the 1980s, American auto makers downsized most of their models, and the Cadillac was no exception. They are typically rented for formal events such as wedding receptions to increase the attractiveness of the chairs and decor. The Cimarron and Seville models marked a beginning of "smaller" cars for the Cadillac line. A chair cover is a temporary fabric cover for a side chair. Indeed, Cadillac was so confident of the Seville that it was exported to Europe, but it faced stiff opposition. If matched to a glider, the ottoman may be mounted on swing arms so that the ottoman rocks back and forth with the main glider. The Allante's styling influenced other Cadillacs, especially the Seville, which adopted its sharper, tailored lines. An ottoman is a short stool to be used as a footrest but can sometimes be used as a stool. The car was, sadly, not a commercial success, but today stands out as a modern classic and more than able to hold its own, image-wise, next to its Mercedes-Benz SL rival. In place of a built-in footrest, some chairs come with a matching ottoman. The greatest challenge to the imports was the Cadillac Allante, a convertible designed by Pininfarina of Italy, and built on what was touted as the world's longest production line—with the car's bodies fabricated in Italy and flown by Boeing 747 to the United States to meet their transmission and engine. Canada's Canadian General Standards Board CAN/CGSB 44.15M [6] on "Straight Stacking Chair, Steel"). Some new design approaches were tried: the Seville, for instance, had gracefully rounded wheel arches with a hint of chrome. Governments will often issue standards for purchases by government agencies (e.g. The mid-1980s saw Cadillac try to rebuild its image, aware that European and Japanese imports were on a rise, and with Honda launching its American luxury division, Acura. Large institutions that make bulk purchases will reference these standards within their own even more detailed criteria for purchase [5]. The 4100's problems cost Cadillac the loyalty of many customers. Under these higher loads, the chair may be damaged, but it must not fail catastrophically. It suffered from coolant leaks, warped intake manifolds and warped heads. The specification further defines heavier "proof" loads that chairs must withstand. This proved to be one of the worst engines ever built. It specifies things like[4]:. The 4100 (4.1 liter) V8 engine was used widely in Cadillacs in the late 1980's. The Business and Institutional Furniture Manufacturer's Association (BIFMA) defines BIFMA X5.1 for testing of commercial-grade chairs. Company marketing hailed the engine as cutting-edge technology, but it proved unreliable and was dropped the next year in favor of a family of smaller aluminum V8 engines rushed into production. ASTM E1822-02b defines the combustibility of chairs when they are stacked. Introduced in 1981, this 368 in³ (6.0 L) engine sequentially shut down cylinders as demand dropped. ASTM F1858-98 specifies lawn chairs. Another low point during the early 1980s was the variable displacement engine, branded the L62 V8-6-4 engine. ISO 7174 specifies stability of rocking and tilting chairs. Although the motoring press lauded the first Cadillac manual transmission in decades, the automatic's extra cost also rankled buyers. Bean bag chairs are specified by ANSI standard ASTM F1912-98[3]. Buyers also objected to the Cimmaron's four-cylinder engine and low level of standard equipment. Dental chairs are specified by ISO 6875. Buyers rejected this model for being too close to the considerably cheaper Chevrolet — unlike the Seville, which did not resemble the Nova or other GM X-cars, the Cimarron was almost indistinguishable from the down-market versions. There are multiple specific standards for different types of chairs. However, trying to extend its brand further downward to appeal to younger buyers, Cadillac launched in 1981 (for the 1982 model year) the compact Cimarron, a warmed-over Chevrolet Cavalier as a rival to the BMW 3-series. ISO 9241-5:1988[2], "Ergonomic requirements for office work with visual display terminals (VDTs) -- Part 5: Workstation layout and postural requirements " is the most common one for modern chair design. Ironically, GM's other division, Detroit Diesel had had decades of experience building Diesel engines. Design considerations for chairs have been codified into standards. The engine was notoriously unreliable and smoky. Open center seats where a soft material is attached to the tops of chair legs or between stretchers to form the seat. This was a disaster for GM. Some systems include: Solid center seats where a solid material forms the chair seat. Due to gasoline shortages, Cadillac offered a "dieselized" (converted from gasoline use) LF9 350-cubic-inch (5.7L) V8 engine, in its full-size cars from 1979 to 1981. Chair seats vary widely in construction and may or may not match construction of the chair's back. It launched a smaller car around the size of the Mercedes-Benz 300, the Seville, based on a Chevrolet Nova platform, which became a success for the marque. See also seats in movie theaters, and pictures of benches with and without arm rests. Its staple De Ville and Fleetwood lines were downsized for 1977 and again for 1985. A loveseat in particular, has no arm rest in between. As with most American brands, Cadillac was forced to downsize its offerings between the 1973 and 1979 fuel crises. Arm rests prevent or complicate both desired and undesired proximity. The build quality also became poorer when measured against German rivals. in public transport and other public places, and to prevent lying on the bench or coach. However, the 1970s saw vehicles memorable for other types of excess: engine size, for one (the Eldorado featured an 8.2-litre engine at one point), weight, and physical bulk. The latter may be provided for comfort, but also for privacy e.g. There were high points, such as the launch of the Eldorado two-door personal luxury car in 1967, with its simple, elegant design—a far cry from the tail-fin and chrome excesses of the 1950s. A couch, bench, or other arrangement of seats next to each other may have arm rest at the sides and/or arm rests in between. Cadillac suffered from the malaise that set in to the American auto industry in the late 1970s to the late 1980s. Hence in some chair designs, the armrest is not continuous to the chair back, but is missing in the elbow area. Somewhat surprisingly for a marque with such a strong design heritage, Cadillac has resisted the temptation to produce any "retro" models such as the revived Ford Thunderbird or the VW New Beetle, and has instead pressed ahead with a new design philosophy for the 21st century called "art and science"[1] which it says "incorporates sharp, shear forms and crisp edges - a form vocabulary that expresses bold, high-technology design and invokes the technology used to design it.". Armrests should support the forearm and not the sensitive elbow area. The tailfin style gave birth to the enduring vertical-tailight pattern, which is a subtle trademark of the Cadillac line (the opposite of the horizontal tailight pattern which is a likewise subtle trademark of rival Lincoln.). Armrests further have the function of making entry and exit from the chair easier (but from the side it becomes more difficult). Nevertheless, Cadillacs retained their tailfins through 1964, and suggestions of them remain in the peaked rear fenders of many models even to this day. If so, armrests will support part of the body weight through the arms if the arms are resting on the armrests. At this point, Bill Mitchell succeeded Harley Earl as styling chief, and his preference for more austere design combined with changing buyer tastes caused the excess to be rapidly toned down, starting in 1960. A chair may or may not have armrests. Cadillac's first tailfins, inspired by the twin rudders of the Lockheed P-38 Lightning, appeared in 1948; the 1959 Cadillac was the epitome of the tailfin craze, with the most recognizable tailfins of any production automobile. For adjustable chairs, the aforementioned principles are applied in adjusting the chair to the individual occupant. Earl, innovated many of the styling features that came to be synonymous with the classic (late 1940s-late 1950s) American automobile, including tailfins and wraparound windshields. In some airplanes and stadiums the seat pitch is so small that there is sometimes there is no leg room for the average person. Postwar Cadillacs, incorporating the ideas of General Motors styling chief Harley J. "Seat pitch" is the distance between rows of seats. Cadillac was the first automaker to use the Phillips technology, which was widely adopted in 1940. The buttock-knee length is used to determine "leg room" between rows of chairs. He entered into talks with General Motors and convinced the Cadillac group that his new screws would speed assembly times and therefore increase profits. Elbow rest height is used to determine the height of the armrests. Phillips introduced the Philips screw and driver onto the market. Hip breadth is used for chair width and armrest width. Henry F. Additional anthropometric measurements may be relevant to designing a chair. 1934 brought about a revolution in assembly line technology. Mass produced chairs are typically 38-43 cm deep. By 1940, Cadillac sales had risen 1000% compared to 1934, thus saving Cadillac from extinction. This anthropometric measurement is used to determine the seat depth. By 1934, Cadillac had regained profitability. For someone seated, the buttock popliteal length is the horizontal distance from the back most part of the buttocks to the back of the lower leg. The Board agreed to give Dreystadt 18 months to produce results. Mass produced chairs are typically 17 inches high. At a fateful board meeting, Cadillac president Nicholas Dreystadt gave the GM Board of Directors a 10 minute speech in which he advocated advertising to black consumers so as to increase sales. The popliteal height, after adjusting for heels, clothing and other issues is used to determine the height of the chair seat. In 1932, after Cadillac suffered from record low sales and charges of discrimination against black customers, Alfred Sloan created a committee to consider the discontinuation of the Cadillac line. (The term "sitting height" is reserved for the height to the top of the head when seated.) For American men, the median popliteal height is 16.3 inches and for American women it is 15.0 inches[1]. In the 1930s, Cadillac added cars with 12- and 16-cylinder engines to their range, many of which were fitted with custom coach-built bodies; these engines were remarkable at the time for their ability to deliver a combination of high power, silky smoothness and quietness. It is sometimes called the "stool height". Pre-World War II Cadillacs were well-built, powerful, mass-produced luxury cars, aimed at an upper class market, below that of such ultra-exclusive marques such as Pierce-Arrow and Duesenberg. For someone seated, the popliteal height is the distance from the underside of the foot to the underside of the thigh at the knees. That model remained in production until 1940. The two most relevant anthropometric measurement for chair design is the popliteal height and buttock popliteal length. About this time, automobile stylist, Harley Earl, whom Cadillac had recruited in 1926 and who was to head the new Art & Color section starting in January 1928, designed for 1927 a new, smaller "companion" car to the Cadillac which he called the La Salle, after another French explorer, René Robert Cavelier, Sieur de La Salle. Anthropometric statistics may be gathered for mass produced chairs. Other innovations included the first V8 engine in mass production in 1915; shatter-resistant safety glass in 1926; and the first fully synchronized transmission (with gears "locked" in relation to one another to prevent clashing upon execution of a shift) in 1928. Individuals may be measured for a custom chair. Originally marketed as a convenience device for female drivers, the electric starter developed by Charles Kettering was first used on the production models of 1912. Actual chair dimensions are determined by measurements of the human body or anthropometric measurements. In 1911, Cadillac was the first gasoline internal combustion engine auto to incorporate electric start, as opposed to earlier crank start. By matching the shape of the occupant's buttocks, weight is distributed and pressure at any given point is reduced. The latter two of which were custom made by aftermarket manufacturers, GM does not produce any such vehicles on its own. A contoured seat pan attempts to distribute weight without padding. The Cadillac line was also GM's default marque for "commercial chassis" institutional vehicles, such as ambulances, limousines, hearses, and funeral home flower cars. Where padding is not desirable, contouring may be used instead. Cadillac became General Motors' prestige division, devoted to the production of large luxury vehicles. For example, in hot climates, padding with fabric or plastic covers is often uncomfortable against the skin. Cadillac was purchased by the General Motors conglomerate in 1909. There may be cases where padding is not desirable. The Dewar Trophy was an annual award for the most important advancement of the year in the automobile industry. Chairs that have padding that is the same density front and back will feel soft in the back area and hard to the underside of the knees. As a result of these tests, the Cadillac Automobile Company was awarded the Dewar Trophy for 1908 (actual award date was Feb 1909). Since most of the body weight is supported in the back of the seat, padding there should be firmer than the front of the seat which only has the weight of the legs to support. Trophy! Parts interchangeability could not have been proven in any other more appropriate way. In lieu of padding, flexible materials, such as wicker, may be used instead with similar effects of distributing the weight. It came out the winner of the R.A.C. Spreading the area reduces the pressure at any given point. On completion of the test, one of the cars was placed under lock and key where it remained until the start of the 2000 miles (3200 km) Reliability Trials, several months later. The same body weight over a smaller area means greater pressure on that area. Using only wrenches and screwdrivers the 3 cars were re-assembled and on Friday March 13 they completed a mandatory 500 mile (800 km) run. A hard wood chair feels hard because the contact point between the occupant and the chair is small. Their 721 component parts were scrambled in one heap; 89 parts requiring extreme accuracy were withdrawn from the heap,locked away at the Brooklands club house and replaced with new parts from the showroom stock. However, padding does distribute the weight by increasing the area of contact between the chair and the body. They were driven 25 miles to the Brooklands race track at Weybridge where they completed another 25 miles (40 km) before being put under lock and key until Monday March 2, 1908 when they were released and disassembled completely. Padding will not shift the weight to different parts of the body (unless the chair is so soft that the shape is altered). In Feb to Mar 1908, three Model K Cadillacs (1907 production) were released from the stock of Frederick Bennett (UK agent for Cadillac) at the Heddon Street showroom in London to compete in the annual Royal Automobile Club's Standardization Test. Padding can be on the seat of the chair only, on the seat and back, or also on any arm rests and/or foot rest the chair may have. The Cadillac's biggest selling point was precision manufacturing and, therefore, reliability; it was simply a better made vehicle than its competition. Many chairs are padded or have cushions. In any case, the new Cadillac was shown at the New York Auto Show the following January, where it impressed the crowds enough to gather over two thousand firm orders. A sit-stand chair distributes most of the weight of the occupant to the feet.
