Last Month General Motors Co. decided to sale their European Opel unit to Canadian auto parts maker Magna International. This month however, General Motors Co. has decided to keep Opel themselves.

This decision was made Tuesday after a long meeting in Detroit; the CEO of General Motors Fritz Henderson reported that General Motors will present its reconstructing plan forOpel to the German government soon. Magna's co-CEO Siegfried Wolf reported that Magna would continue to support both General Motors and Opel through-out the future.

General Motors has had a very tough time through-out this recession. They lost more than $8 billion through-out the past 4 years and have received $50 billion forgovernment aid. They announced the selling Opel in hope that their profit would go up in both Latin America and Asia.

At 54,000 workers and sells in cars such as Vauxhall, Opel, Cadillac and Chevrolet General Motors has the fourth highest auto sales in Europe coming in after VW Group, PSA Group and Ford Motor CO. European sales dropped 6.6 percent through the month of December and sales of Vauxhall and Opel cars have dropped even further coming in at 11.4 percent.


While General Motors had to file for bankruptcy earlier this year, Opel was kept out of the filing. Sixty-five percent of Opel was under the care of a trust while the other 35 percent was withheld by General Motors.

General Motors was not the only company having many problems during this recession. Several auto industries went into bankruptcy and were kept open due togovernment aid. Numerous companies ended up selling out some of their money making cars while others had to discontinue some famous cars. Now auto industries are beginning to pick up but they are still not doing so hot because American's just do not have the money to buy cars.


During this summer, the "Cash for Clunkers" program was a huge success among auto industries. American's were able to use their rebates so they could trade in their old gas chugging cars for a new fuel efficient one. All the while this program was great for business, when the program ended so did the business.

Unemployment rates keep rising which means more people are becoming jobless and less able to afford their mortgage let alone a new car. It is like a domino effect and it all starts with unemployment, once unemployment is figured out and American's stop losing their jobs and others find jobs, the economy will strengthen thus getting us far way for the outskirts of a recession.

Grand Prix motor refers to the top class of motorcycle racing, currently divided into three classes of machine different: 125cc, 250cc and MotoGP (over 990cc). Motors used in MotoGP is made specifically for motor racing, and not sold to the public (street version of the motor for 125 and 250cc classes available). This contrasts with the various production categories of racing, such as World Superbike, that feature modified versions of motorcycles available for general.

History
Road Racing World Championship was first organized by the Federation Internationale de Motocyclisme (FIM) in 1949. At that traditionally have been held several races at each event for different classes of motors, based on engine capacity, and classes for sidecars (Motor bersespan). Existing classes when it is 50cc, 125cc, 250cc, 350cc, and 500cc for single-seater racing motorcycles, and 350cc and 500cc sidecars for motorcycles. Entering the 1950s and throughout the 1960s, motorcycle engines, four did not dominate the entire class. In the late 1960s, the motor engined two did not begin to master the small classes. In the 1970s, motorcycle engines, two did not really get rid of 4 stroke engines. In 1979, Honda tried to restore the engine 4 stroke the top class by lowering the motor NR500, but this project failed, and in 1983 Honda even winning with a 500cc bike not his second. In 1983, 350cc class finally abolished. 50cc class was replaced by the year 1984 80cC class, but class often dominated by the Spaniard and the Italian was finally abolished in 1990.



Class sidecars are also excluded from the world championships in the 1990s, leaving the 125cc, 250cc, and 500cc classes.

GP 500, the premier class of Grand Prix motor racing, has changed dramatically in recent years 2002. From the mid-1970s until 2001 the top class of GP racing limited four-cylinder and engine capacity of 500cc, both types of engines 4 stroke or 2 stroke. As a result, which can survive engine is 2-strokes, produces power and greater acceleration. In 2002 for the first time, manufacturers are allowed to enlarge the total capacity of a special machine for 4 stroke engine to a maximum of 990cc, and gave freedom to choose the number of cylinders used between three to six with a certain weight limit. With the motor bolehkannya 4 990cc no, the 500 GP class renamed to MotoGP. After the year 2003 does not exist anymore two machines that do not fall in the MotoGP class. For 125cc and 250cc classes in particular still using two machines do not.



Race for the MotoGP class is currently held as many as 17 series in 15 different countries (Spain held the third race weekend). Used in the title race every weekend with several stages.







Friday free practice at the title and the first official practice, and then carried out practice Saturday both official and QTT, where the drivers trying to make the best time to record determine their starting position. Own race was held on Sunday, although there was a series of Saturday is held in the Netherlands and Qatar. Grid (row starting position) consists of three drivers per line and usually every racing series was followed by about 20 drivers. Racing held for about 45 minutes and the driver raced along the specified number of rounds, without entry to the pit change tires or refuel.

As a result, are able to survive is the engine two-strokes, produces power and greater acceleration. In the year 2002 until 2006 for the first time, manufacturers are allowed to enlarge the total capacity of a special machine to machine can not be a maximum of four 990cc, and 800cc in the season turned into 2007.pabrikan also given the freedom to choose the number of cylinders used between three to six with a weight limit particular. With the motor bolehkannya cc 4 stroke was large, the 500 GP class renamed to MotoGP. After the year 2003 there was no second machine that did not go down in the MotoGP class. For 125cc and 250cc classes in particular are still not using two machines.

Racing will be repeated in case of a fatal accident in the early races. The composition of the grid is not changed according to qualifying results. The drivers may enter the pit, if only to replace the motor because of rain during the race.


MotoGP Racing success is inseparable from the organizations involved within a few organizations who are members of the commission, among others FIM Grand Prix, Drona, IRTA and MSMA.

FIM (Federation Internationale de Motocyclisme), is the highest body in the world who care about motorcycles. FIM was established in 1904 was not only taking care of motor racing, but also became superintendent of production motorcycles are sold en masse, particularly about the safety and feasibility. In the ordinary motor racing, FIM is the agency in charge of and responsible about the regulatory and technical implementation of the race, also on the status, extent, and the criteria of a motor racing championship.

Drona is the organization administering the MotoGP race, or in other words, Drona is the promoter of the MotoGP championship. Drona is responsible for the quality of care events and also sponsors the event.


IRTA (International Road Racing Team Association), members of this organization consists of teams who follow the MotoGP race. This organization serves to channel the aspirations of the team and the drivers involved. With this organization the drivers can provide input and determine the rights and interests, including the contract value, safety and feasibility of the circuit.

MSMA (Motorcycle Sport Manufacturer Association), an organization composed in MotoGP from the manufacturer, motor manufacturers who follow the MotoGP championship, such as Honda, Yamaha, Ducati, Suzuki, Kawasaki, and other manufacturers. The function of this organization, among others, to decide the technical regulations on the regulation of the motor along with other organizations involved in the commission Grand Prix.


SPECIFICATIONS

Each of the regulations concerning each class is formed by the FIM race as an organization that authorities do it. FIM forming and issuing new regulations that are considered in accordance with the development race. At the beginning of the new MotoGP era in 2002, not 500cc motorcycle-engined 2 and 4 can not be allowed to be used in the 990cc race. Ultimate power from the motor-engine 4 stroke motorcycle engine that outperformed the two did not get rid of the whole machinery of the two no competition, and the next racing season there is no second motor was used.

In the year 2007, FIM will impose new regulations that the MotoGP bikes will be limited to 800cc 4 stroke. Reasons suggested the reduction of engine cylinder capacity is to increase the security of drivers, given the energy and peak velocity generated MotoGP machines has increased dramatically since 2002. MotoGP current speed record is 347.4 km / h printed by Loris Capirossi on a Ducati motorcycle circuit with Catalunya, Barcelona in 2004. As a comparison, the current F1 speed record is 369.9 km / h printed by Antonio Pizonia with BMW cars, the Monza circuit in 2004.

The decision to restrict the choice of engine capacity to 800cc (than with other methods of power restrictions, such as reducing the number of gear transmission is allowed) by the observers Honda MotoGP is very profitable. Honda uses a five-cylinder engine, and only need to reduce one cylinder to fix their machines to suit the new regulations, while other manufacturers have to redesign all of their machines. Restricted to 800cc also led to controversy that seems to present the motor used in the Superbike championship to be the fastest in the 1000cc motor racing circuits around the world.

Machines used in the 125cc class is limited as much as a single cylinder and with a minimum weight of 80 kilograms, while the 250cc class is limited to two silnder with minimum weight 100 pounds.

Motors for the MotoGP class is allowed to use the machine with the number of cylinders between three to six cylinders, and there are variations in the weight restrictions depending on the number of cylinders used. This is due to an engine with more cylinders, power output is also greater, and weight limits are increased. In 2006, the machines used in MotoGP is a four-and five-cylinder engine. Honda uses a five-cylinder, while the Yamaha, Ducati, Kawasaki, and Suzuki used four cylinder.

Motors are used in motor Grandprix made not only for racing only, but also as a venue for power struggles among manufacturers and technological advances. As a result all the MotoGP machines made by using very expensive materials and light such as titanium, and carbon-fiber-reinforced plastic. Motors are also using technology that is not available for public consumption, for example, is a sophisticated electronic devices including telemetry, engine management systems, traction control, carbon disc brakes, and modern engine technology adopted from the F1 car engine technology.


If the motors used in the MotoGP class only raced at world championship level, motors used in the 125cc and 250cc classes are relatively more affordable. The price of a more or less the same 125cc motorcycle with a car. These motors are often used in a national motor racing championships around the world.

One of several key challenges faced by drivers and engineers MotoGP MotoGP bike is how to channel the incredible power of the engine - more than 240 dk (179 kW), through the contact points of two tires and the asphalt surface with a circuit width is only about the human arm. As a comparison, F1 cars generate more than 950 dk (700 kW) but with four tires, so have the point of contact with the asphalt surface ten times wider than the MotoGP bike.
