MG7 II Image02
The MG7 is a mid-size sedan that was built by MG Motor between 2007 and 2013, derived from its British predecessors, Rover 75 and MG ZT to suit Chinese manufacturing and sales. The name was resurrected in 2022 with the launch of the second generation MG7. __TOC__ First generation (2007) Production of the first-generation MG7 started in March 2007. The MG7 received praise from British car magazine ''Auto Express'', who test drove it in May 2008, although it has not officially been sold in the United Kingdom. The MG7 came in two variants, the first which resembles the Mark I MG ZT, with twin front lights, and the second which resembles the Mark II Rover 75 V8. A long wheelbase version, called the MG7L, features the deeper radiator grille of the Rover 75 V8. The MG7 came in two trim levels: 'Classic' which features a slatted grille, and 'Sport' with a mesh grille. The look of the 7 has changed very little from the ZT and 75; the only noticeable difference is freshly designed L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MG Motor
MG Motor is a British automotive manufacturer owned by SAIC Motor, a Chinese state-owned carmaker based in Shanghai. It uses the MG marque, founded in Oxford, England, in 1924. SAIC Motor gained control of the marque in December 2007 by acquiring Nanjing Automobile Corporation (NAC), which had bought the brand from the defunct MG Rover Group in 2005. Currently, MG operates as a division within SAIC's passenger vehicle branch. MG vehicles are designed and developed by SAIC, and manufacturing mainly takes place at SAIC's plants in China. Additionally, SAIC produces MG vehicles in Thailand, India, Indonesia, and Taiwan for their respective regional markets. The brand briefly assembled cars at the Longbridge plant in the UK from 2007 to 2016, before reverting to sourcing vehicles directly from China. In China, MG is also known by its Chinese name , and it is one of several passenger car brands directly owned by SAIC, alongside IM Motors, Rising Auto, Roewe and Maxus ( LDV fo ...

Automatic Transmission
An automatic transmission (AT) or automatic gearbox is a multi-speed transmission (mechanics), transmission used in motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. The 1904 Sturtevant "horseless carriage gearbox" is often considered to be the first true automatic transmission. The first mass-produced automatic transmission is the General Motors ''Hydramatic'' two-speed hydraulic automatic, which was introduced in 1939. Automatic transmissions are especially prevalent in vehicular drivetrains, particularly those subject to intense mechanical acceleration and frequent idle/transient operating conditions; commonly commercial/passenger/utility vehicles, such as buses and waste collection vehicles. Prevalence Vehicles with internal combustion engines, unlike electric vehicles, require the engine to operate in a narrow range of rates of rotation, requiring a gearbox, operated manually or automatically, to drive t ...

Dual-clutch Transmission
A dual-clutch transmission (DCT) (sometimes referred to as a twin-clutch transmission) is a type of multi-speed motor vehicle, vehicle Transmission (mechanics), transmission system, that uses two separate clutches for odd and even gear train, gear sets. The design is often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as one unit. In car and truck applications, the DCT functions as an automatic transmission, requiring no driver input to change gears. The first DCT to reach production was the ''Easidrive'' automatic transmission introduced on the Hillman_Minx#Audax_design_Hillman_Minx_(Series_I_to_Series_VI,_1956–1967), 1961 Hillman Minx mid-size car. This was followed by various eastern European tractors through the 1970s (using manual operation via a single clutch pedal), then the Porsche 962, Porsche 962 C racing car in 1985. The first DCT of the modern era was used in the 2003 Volkswagen Golf Mk4#R32 ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Turbocharger
In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement. Turbochargers are distinguished from superchargers in that a turbocharger is powered by the kinetic energy of the exhaust gases, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger.

Petrol Engine
A petrol engine (gasoline engine in American and Canadian English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as '' E10'' and '' E85''). They may be designed to run on petrol with a higher octane rating, as sold at petrol stations. Most petrol engines use spark ignition, unlike diesel engines which run on diesel fuel and typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio. History The first practical petrol engine was built in 1876 in Germany by Nicolaus August Otto and Eugen Langen, although there had been earlier attempts by Étienne Lenoir in 1860, Siegfried Marcus in 1864 and George Brayton in 1873. Design Thermodynamic cycle Most petrol engines use either the four-stroke Otto cycle or the two-stroke cycle. Petrol engines have also ...

Fastback
A fastback is an automotive styling feature, defined by the rear of the car having a single slope from the roof to the tail. The kammback is not a fastback design with a roofline that tapers downward toward the car's rear before being cut off abruptly. Some models, such as the Ford Mustang, have been marketed explicitly as fastbacks, often to differentiate them from other body styles (e.g. coupé models) in the same model range. Definition A fastback is often defined as having a single slope from the roof to the rear of the vehicle. Traditionally a fastback will have a trunk opening that is separate from the rear window which remains in a fixed position. The term "fastback" is not interchangeable with "liftback"; the former describes the car's shape, and the latter refers to a roof-hinged tailgate that lifts upwards for storage area access. More specifically, the '' Road & Track Illustrated Automotive Dictionary'' defines the fastback as A closed body style, usually ...

Air Bag
An airbag is a vehicle occupant-restraint system using a bag designed to inflate in milliseconds during a collision and then deflate afterwards. It consists of an airbag cushion, a flexible fabric bag, an inflation module, and an impact sensor. The purpose of the airbag is to provide a vehicle occupant with soft cushioning and restraint during a collision. It can reduce injuries between the flailing occupant and the vehicle's interior. The airbag provides an energy-absorbing surface between the vehicle's occupants and a steering wheel, instrument panel, body pillar, headliner, and windshield. Modern vehicles may contain up to ten airbag modules in various configurations, including driver, passenger, side-curtain, seat-mounted, door-mounted, B- and C-pillar mounted side-impact, knee bolster, inflatable seat belt, and pedestrian airbag modules. During a crash, the vehicle's crash sensors provide crucial information to the airbag electronic controller unit (ECU), including colli ...

Autocar (magazine)
''Autocar'' (stylized in all caps) is a weekly British automobile magazine published by Haymarket Media Group. It was first published in 1895 and refers to itself as "the world's oldest car magazine". Mark Tisshaw is editor and other team members include Steve Cropley, Rachel Burgess, James Attwood, Matt Prior, Matt Saunders and Felix Page. ''Autocar'' has several international editions, including China, India, New Zealand, and South Africa. History The publication was launched as ''The Autocar'' by Yattendon Group, Iliffe and Son Ltd. "in the interests of the mechanically propelled road carriage" on 2 November 1895 when, it is believed, there were only six or seven cars in the United Kingdom. L. J. K. Setright suggests that the magazine was set up by Henry Sturmey (1857–1930), Henry Sturmey as an organ of propaganda for Harry J. Lawson, founder of the Daimler Company and a journalist on the magazine in its early days. Henry Sturmey stood down as editor of ''The ...

Euro IV
The European emission standards are vehicle emission standards that regulate pollution from the use of new land surface vehicles sold in the European Union and European Economic Area member states and the United Kingdom, and ships in European territorial waters. These standards target air pollution from exhaust gases, brake dust, and tyre rubber pollution, and are defined through a series of European Union directives that progressively introduce stricter limits to reduce environmental impact. Euro 7, agreed in 2024 and due to come into force in 2026, includes non-exhaust emissions such as particulates from tyres and brakes. Until 2030 fossil fueled vehicles are allowed to have dirtier brakes than electric vehicles. Background In the European Union, emissions of nitrogen oxides (), total hydrocarbon (THC), non-methane hydrocarbons (NMHC), carbon monoxide (CO) and particulate matter (PM) are regulated for most vehicle types, including cars, trucks (lorries), loc ...
