Tenth-Generation Japanese Toyota Corolla (only sold in Japan)




# A rearview monitor displays an image of the area to the rear of the vehicle while backing up to reduce the burden on the driver when parking (standard on all Corolla Axios).# The Corolla Fielder features the world's first one-touch double-folding rear seats with backrests that can be folded flat with a single flip of a lever located in the rear cargo space.# The optional advanced Intelligent Parking Assist system supports steering operations when parallel parking and backing into a parking space.  Ultrasonic sensors installed on the front of the vehicle detect other parked vehicles and based on the results estimate the physical dimensions of a vacant parking space and set the target parking position.# The Corolla Axio features a new Pre-crash Safety System that uses millimeter-wave radar.  When the millimeter-wave radar detects a high risk of collision, the Pre-crash Seatbelts provide better initial restraint capabilities for passengers while the Pre-Crash Brake Assist system decelerates the vehicle to reduce the collision speed and contribute to less collision-caused damage.# The new Radar Cruise Control system detects and monitors the preceding vehicle and the lane, maintaining a fixed distance according to the preceding vehicle's speed within a preset range of speed.

2010 BMW 5-series





The new 5-series is being built off an entirely new chassis, with double wishbones in the front, like on the new X5. The move is designed to give better control and road grip around corners, according to the chassis engineers. With the aid of the extremely fast Flex-Ray automotive network communications protocol, the adaptive shock absorbers is set to become more effective, as will active steering. BMW will also be updating its iDrive system for the new 5-series, making life a little easier with the addition of yet another pair of programmable buttons. Those that think the standard 5-series isn’t sporty enough will have to wait for a few more years until the new M5 turns up with its V10 motor and more power than the 507hp offered in today’s edition. The M version will be the only 5-series model offered with a new dual clutch gearbox (similar to VW’s DSG technology). The standard version will instead be fitted with an 8-speed automatic transmission that will take the fight to Lexus. This gearbox is being developed by ZF, which will also manufacture a new four wheel drive system that will feature in the new Five. A new 5-series wouldn’t be complete without the introduction of more electronic driver’s aids, and this time BMW is bringing Dynamic Performance Control to the table. The system actively distributes torque between the wheels, depending on how the car acts during a turn. The result is increased security and the ability to handle larger side forces. The new differential will also come in the new 3-series and potentially even the 1-series as an option. A full-hybrid system, featuring an electric motor in parallel with an engine, is not currently planned for the new 5-series, which instead is likely to feature the same system already used in the 1-series. This light-hybrid system consists of an electric starter motor that’s connected to the crankshaft and can function as both a generator and a propulsion system, spinning the engine during initial off the line acceleration. The light-hybrid will be available in both diesel and petrol versions and expect a new V8 diesel engine to make its debut in the next-gen model. The two-mode hybrid transmission that was developed by BMW together with General Motors and DaimlerChrysler is mostly aimed at bigger vehicles such as trucks and SUVs. The design features dual motors, and an advanced control system that can allow both engines can be turned on simultaneously, and to regenerate electric power during braking. This two-mode system, however, is not currently planned for the next generation 5-series, although BMW has not eliminated the possibility that a similar technology can be added towards the end of the model’s life cycle. We’ll have to make do with the light hybrid at the moment since BMW feels it has already succeeded in heavily reducing the fuel consumption of their engines. However, it remains to be seen whether or not BMW will be able to reach the EU’s new requirements for average CO2 emissions of 130g/km by 2012.

Automobile industry in Pakistan

The Automobile industry has been an active and growing field in Pakistan for a long time, however not as much established to figure in the prominent list of the top automotive industries. Pakistan has a large range of motorbikes which are used throughout the whole of the country for terms of transportation. In the past, there have been talks about expanding the industry however nothing has been heard till now. Cars are imported to the country in large figures from Japan and people buy mostly manual cars rather than automatic.

Steam




Steam power, usually using an oil- or gas-heated boiler, was also in use until the 1930s but had the major disadvantage of being unable to power the car until boiler pressure was available (although the newer models could achieve this in well under a minute). It has the advantage of being able to produce very low emissions as the combustion process can be carefully controlled. Its disadvantages include poor heat efficiency and extensive requirements for electric auxiliaries

Electric




The first electric cars were built around 1832, well before internal combustion powered cars appeared. For a period of time electrics were considered superior due to the silent nature of electric motors compared to the very loud noise of the gasoline engine. This advantage was removed with Hiram Percy Maxim's invention of themuffler in 1897. Thereafter internal combustion powered cars had two critical advantages: 1) long range and 2) high specific energy (far lower weight of petrol fuel versus weight of batteries). The building of battery electric vehicles that could rival internal combustion models had to wait for the introduction of modern semiconductorcontrols and improved batteries. Because they can deliver a high torque at low revolutions electric cars do not require such a complex drive train and transmission as internal combustion powered cars. Some post-2000 electric car designs such as the Venturi Fétish are able to accelerate from 0-60 mph (96 km/h) in 4.0 seconds with a top speed around 130 mph (210 km/h). Others have a range of 250 miles (400 km) on the United States Environmental Protection Agency (EPA) highway cycle requiring 3-1/2 hours to completely charge

Biofuels




Ethanol, other alcohol fuels (biobutanol) and biogasoline have widespread use an automotive fuel. Most alcohols have less energy per liter than gasoline and are usually blended with gasoline. Alcohols are used for a variety of reasons - to increase octane, to improve emissions, and as an alternative to petroleum based fuel, since they can be made from agricultural crops. Brazil's ethanol program provides about 20% of the nation's automotive fuel needs, as a result of the mandatory use of E25 blend of gasoline throughout the country, 3 million cars that operate on pure ethanol, and 6 million dual or flexible-fuel vehicles sold since 2003.that run on any mix of ethanol and gasoline. The commercial success of "flex" vehicles, as they are popularly known, have allowed sugarcane based ethanol fuel to achieve a 50% market share of the gasoline market by April 2008.

Gasoline




Gasoline engines have the advantage over diesel in being lighter and able to work at higher rotational speeds and they are the usual choice for fitting in high-performance sports cars. Continuous development of gasoline engines for over a hundred years has produced improvements in efficiency and reduced pollution. Thecarburetor was used on nearly all road car engines until the 1980s but it was long realised better control of the fuel/air mixture could be achieved with fuel injection. Indirect fuel injection was first used in aircraft engines from 1909, in racing car engines from the 1930s, and road cars from the late 1950s.Gasoline Direct Injection (GDI) is now starting to appear in production vehicles such as the 2007 (Mark II) BMW Mini. Exhaust gases are also cleaned up by fitting a catalytic converter into the exhaust system. Clean air legislation in many of the car industries most important markets has made both catalysts and fuel injection virtually universal fittings. Most modern gasoline engines also are capable of running with up to 15% ethanol mixed into the gasoline - older vehicles may have seals and hoses that can be harmed by ethanol. With a small amount of redesign, gasoline-powered vehicles can run on ethanol concentrations as high as 85%. 100% ethanol is used in some parts of the world (such as Brazil), but vehicles must be started on pure gasoline and switched over to ethanol once the engine is running. Most gasoline engined cars can also run on LPG with the addition of an LPG tank for fuel storage and carburettor modifications to add an LPG mixer. LPG produces fewer toxic emissions and is a popular fuel for fork-lift trucks that have to operate inside buildings.

Diesel




Diesel-engined cars have long been popular in Europe with the first models being introduced as early as 1922 by Peugeot and the first production car, Mercedes-Benz 260 D in 1936 by Mercedes-Benz. The main benefit of diesel engines is a 50% fuel burn efficiency compared with 27% in the best gasoline engines. A down-side of the Diesel engine is that better filters are required to reduce the presence in the exhaust gases of fine soot particulates called diesel particulate matter. Manufacturers are now starting to fit[when?] diesel particulate filtersto remove the soot. Many diesel-powered cars can run with little or no modifications on 100% biodiesel and combinations of other organic oils.

Production




The large-scale, production-line manufacturing of affordable automobiles was debuted by Ransom Olds at hisOldsmobile factory in 1902. This concept was greatly expanded by Henry Ford, beginning in 1914.As a result, Ford's cars came off the line in fifteen minute intervals, much faster than previous methods, increasing productivity eight fold (requiring 12.5 man-hours before, 1 hour 33 minutes after), while using less manpower.It was so successful, paint became a bottleneck. Only Japan black would dry fast enough, forcing the company to drop the variety of colors available before 1914, until fast-drying Duco lacquer was developed in 1926. This is the source of Ford's apocryphal remark, "any color as long as it's black".In 1914, an assembly line worker could buy a Model T with four months' pay

HIstory



Ferdinand Verbiest, a member of a Jesuit mission in China, built the first steam-powered vehicle around 1672 which was of small scale and designed as a toy for the Chinese Emperor that was unable to carry a driver or a passenger, but quite possibly, was the first working steam-powered vehicle ('auto-mobile'). Although Nicolas-Joseph Cugnot is often credited with building the first self-propelled mechanical vehicle or automobile in about 1769 by adapting an existing horse-drawn vehicle, this claim is disputed by some[citation needed], who doubt Cugnot's three-wheeler ever ran or was stable. What is not in doubt is that Richard Trevithick built and demonstrated his Puffing Devil road locomotive in 1801, believed by many to be the first demonstration of a steam-powered road vehicle although it was unable to maintain sufficient steam pressure for long periods, and would have been of little practical use. In Russia, in the 1780s, Ivan Kulibin developed a human-pedalled, three-wheeled carriage with modern features such as a flywheel, brake, gear box, and bearings; however, it was not developed further. François Isaac de Rivaz, a Swiss inventor, designed the first internal combustion engine, in 1806, which was fueled by a mixture of hydrogen and oxygen and used it to develop the world's first vehicle, albeit rudimentary, to be powered by such an engine. The design was not very successful, as was the case with others such as Samuel Brown, Samuel Morey, and Etienne Lenoir with his hippomobile, who each produced vehicles (usually adapted carriages or carts) powered by clumsy internal combustion engines.In November 1881 French inventor Gustave Trouvé demonstrated a working three-wheeled automobile that was powered by electricity. This was at the International Exhibition of Electricity in Paris. Although several other German engineers (including Gottlieb Daimler, Wilhelm Maybach, and Siegfried Marcus) were working on the problem at about the same time, Karl Benz generally is acknowledged as the inventor of the modern automobile.An automobile powered by his own four-stroke cycle gasoline engine was built in Mannheim, Germany by Karl Benz in 1885 and granted a patent in January of the following year under the auspices of his major company, Benz & Cie., which was founded in 1883. It was an integral design, without the adaptation of other existing components and including several new technological elements to create a new concept. This is what made it worthy of a patent. He began to sell his production vehicles in 1888.
