Saturn Aura
The Saturn Aura is a four-door, five-passenger front engine/front-wheel drive mid-sized sedan manufactured and marketed by GM's Saturn subsidiary over a single generation from 2006 to 2009. The car launched one year before the seventh generation Chevrolet Malibu, its most closely related platform companion. The Aura debuted as a concept car at the North American International Auto Show in January 2005, followed by the production model which debuted at the 2006 New York Auto Show. As the largest sedan in the Saturn range, production commencing in North America in the summer of 2006 for the 2007 model year. The Aura superseded the Saturn L-Series, which was discontinued after the 2005 model year. Although Saturn had not originally intended to use the ''Aura'' name for the production vehicle, the concept vehicle proved popular and the name was retained. The Aura was part of a product rejuvenation for Saturn, intended to make the brand profitable and competitive with European imp ...

Saturn Corporation
The Saturn Corporation, also known as Saturn LLC, was an American automobile manufacturer, a registered trademark established on January 7, 1985, as a subsidiary of General Motors. The company was an attempt by GM to compete directly with Automotive industry in Japan, Japanese imports and transplants, initially in the American compact car market. The company was known for its 'no-haggle' sales technique. Saturn marketed itself as a "different kind of car company" and operated quasi-independently from its parent company,—comprehensively introducing a new car, dealer network, pricing structure, workforce and independently managed manufacturing plant in Spring Hill, Tennessee. The first cars themselves launched five years after the company's inception, and they advanced GM's spaceframe construction—manifesting Saturn's market proposition with their dent-resistant polymer exterior panels. Over time, as Saturn drained resources from GM's extensive brand network, the brand would be ...

Straight-four Engine
A straight-four engine (also referred to as an inline-four engine) is a four-cylinder Reciprocating engine, piston engine where cylinders are arranged in a line along a common crankshaft. The majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a Slant-4 engine, slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer ...

North American International Auto Show
The Detroit Auto Show, formerly known as the North American International Auto Show (NAIAS), is an annual auto show held in Detroit, Michigan. Hosted at Huntington Place (formerly Cobo Center) since 1965, it is among the largest auto shows in North America, and is widely regarded as one of the automotive industry's most important events. The show is organized by the Detroit Auto Dealers Association (DADA), and has been held annually in January for much of its recent history. It is usually open to the general public for 1–2 weeks, preceded by previews for industry employees and media, and a Black tie, black-tie "charity preview" fundraiser for local children's charities. History In 1899, William E. Metzger helped organize the Detroit Auto Show, only the second of its kind, after the 1898 Paris Auto Show. An auto show was held in Detroit in 1907 at Beller's Beer Garden at Riverside Park and since then annually except 1941–1953. During the show's first decades of existence ...

Concept Car
A concept car (also known as a concept vehicle or show vehicle) is a car made to showcase new styling or new technology. Concept cars are often exhibited at motor shows to gauge customer reaction to new and radical designs which may or may not be produced. General Motors designer Harley Earl is generally credited with inventing the concept car, and did much to popularize it through its traveling Motorama shows of the 1950s. Concept cars never go into production directly. In modern times, all would have to undergo many changes before the design is finalized for the sake of practicality, safety, regulatory compliance, and cost. A "production-intent" prototype, as opposed to a concept vehicle, serves this purpose. Design Concept cars are often radical in engine or design. Some use non-traditional, exotic, or expensive materials, ranging from paper to carbon fiber to refined alloys. Others have unique layouts, such as gullwing doors, three or five (or more) wheels, or sp ...

Buick Regal
The Buick Regal is a line of mid-size cars marketed by Buick since 1973. Serving as the premium mid-size/intermediate car of the Buick product range for nearly its entire production, the Regal initially served as the divisional counterpart of the Pontiac Grand Prix and Oldsmobile Cutlass Supreme; since the late 2000s, the model line has been derived from the Opel Insignia. The Regal also serves as the basis of the high-performance Grand National, Gran Sport (GS), and Buick GNX coupes. Through its production, the Regal has been marketed under a wide variety of body styles, including two-door coupes and four-door sedans (currently in production), along with a 5-door liftback sedan and a 5-door station wagon; the latter (the 2018-2020 Regal TourX) was the first Buick station wagon marketed since the retirement of both the Century and Roadmaster Estates after 1996. The turbocharged LD5 3.8L V6 used in the second generation was used to showcase the motorsports presence ...

Saturn L-Series
The Saturn L-Series is a line of automobiles, sedans and station wagons that were made by Saturn Corporation in Wilmington, Delaware for 2000–2005 model years. Poor sales of the L-Series cars caused GM to cancel the line for 2005. The first L-Series car was built in May 1999, and the last one rolled off the Wilmington line on June 17, 2004, after a short run of 2005 models. About 406,300 L-Series cars were built in this period. The plant was then retooled to build the Pontiac Solstice and Saturn Sky roadsters. The replacement for the L-Series, the Saturn Aura, arrived in August 2006 for the 2007 model-year. The Aura was built on the Epsilon platform, shared with the Pontiac G6, Saab 9-3, and Chevrolet Malibu. Model history *2000: In May 1999 for the 2000 model year, Saturn Corporation introduced the Saturn L-Series as a lineup of sedan and station wagon vehicle models – three sedan models and two station wagon models. The sedan L-Series models were the four-cylinder LS a ...

Mild Hybrid
Mild hybrids (MHEV) (also known as smart hybrids, power-assist hybrids, battery-assisted hybrid vehicles or BAHVs) are generally cars with an internal combustion engine (ICE) equipped with a minimally extended battery and an auxiliary electric combined motor and generator in a parallel hybrid configuration that is only enough for an electric-only mode of propulsion at slow speed and allows the engine to be stopped whenever the car is coasting, braking, or stopped, and then restarted once power is required again. Mild hybrids may employ regenerative braking and some level of power assist to the internal combustion engine. Overview The mild hybrid's electric motor provides greater efficiency through the use of a single device that is essentially an integrated starter/alternator sometimes known as a generator-motor unit. A typical mild-hybrid setup uses a belt-powered generator-motor unit driven off the engine to supply power to a small battery. The generator is also powered throug ...

GM 6T40 Transmission
The Hydra-Matic 6T40 and similar 6T30, 6T45, and 6T50 are transversely-mounted six speed automatic transmissions produced by General Motors. The 6T40, referred to in GM inner circles as the GF6, made its debut in the 2008 Chevrolet Malibu, available with the 2.4 L '' LE5'' ''Ecotec'' engine making , and has since also been made available on the Chevrolet Cruze, Daewoo Tosca and Buick LaCrosse. It features clutch-to-clutch shifting, eliminating the bands used on older transmission designs. GM chose an "on-axis" design as opposed to folding the gearset behind the engine and transferring power through the use of a chain, as is used in most other GM front wheel drive transaxles. Ford Motor Company also produces their own variant, called the 6F35. The Buick Encore uses the 6F35 mated to the 1.4 turbo. The 6T45 differs from the 6T40 in its use of heavier-duty components, allowing it to handle engines with greater torque. The 6T40 and 6T50 are available in front-wheel drive co ...

GM 4T45-E Transmission
The 4T40-E and 4T45-E are a series of automatic transaxles from General Motors. Designed for transverse engine configurations, the series includes 4 forward gears. The 4Txx family replaced the Turbo-Hydramatic 125 transverse three speed automatic introduced in 1980. The "-E" series is electronically controlled and features an automatic overdrive transaxle with an electronically controlled torque converter clutch. Since non-electronic versions of these transmissions do not exist, it is conventional to refer to these models as simply 4T40 and 4T45, leaving out the "-E". The 4T40 and 4T45 were assembled at Windsor Transmission in Windsor, Ontario, Canada. 4T40 The "MN4" 4T40E is able to handle vehicles up to 4000 lb (1814 kg) GVWR. The final drive ratio can vary depending on the car's curb weight and engine power output. 3.91, 3.63, 3.29, 3.05, 3.69, and 3.42 are all of the available ratios used in the 4T40 (and 4T45) transmission; Made possible by using combinations se ...

Hybrid Vehicle
A hybrid vehicle is one that uses two or more distinct types of power, such as submarines that use diesel when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids. Hybrid powertrains are designed to switch from one power source to another to maximize both fuel efficiency and energy efficiency. In hybrid electric vehicles, for instance, the electric motor is more efficient at producing torque, or turning power, while the combustion engine is better for maintaining high speed. Improved efficiency, lower emissions, and reduced running costs relative to non-hybrid vehicles are three primary benefits of hybridization. Vehicle types Two-wheeled and cycle-type vehicles Mopeds, electric bicycles, and even electric kick scooters are a simple form of a hybrid, powered by an internal combustion engine or electric motor and the rider's muscles. Early prototype motorcycles in the late 19th century used the same principle ...

Belt Alternator Starter
BAS (belted alternator starter) is a category of automotive parallel hybrid technology that uses an electric motor to contribute power to the internal combustion engine's crankshaft via a serpentine belt. By mounting this motor generator unit in the conventional location traditionally used for the standard automotive alternator, it permits a low-cost method of adding mild hybrid capabilities such as start-stop, power assist, and mild levels of regenerative braking. BAS systems differ from other mild hybrid systems as they are not run off the vehicle's crankshaft. Toyota In June 2001, Toyota introduced a BAS hybrid system under the Toyota Hybrid System-Mild (THS-M) brand name. It operates similarly to other mild hybrids with a start-stop system, in that it shuts down the engine as the vehicle comes to a stop and instantly restarts it when the brake pedal is released. THS-M is capable of modest power assist during launch acceleration and similarly modest levels of "blended" regener ...
