BMW 8 series Cars in Pakistan


BMW 8 Series

BMW 8 series car has been impressive for many years. BMW has managed to earn huge with these cars and now expected to do a little more. BMW 8-Series was available in several versions: 830i (virtually non-encountered), 840i and 850i. The most interesting is the BMW 850i with a 5-liter V12, which is quite suitable for the role of "car for every day." Most often BMW salons left exactly 300-strong 850i and 850ci.

Why is it so special?

BMW 8 Series E31 is one of the most unique products of the Bavarian brand, after the M1 model. The work on the G8 began in 1986 and ended in 1989. The cost of the project was 1.5 billion then German stamps. E31 was not only luxurious but also strong. The Germans quickly dubbed him a "Ferrari murderer." It was the first BMW to be able to compete with the best cars of the GT type. However, none of the independent journalists praised the car for its performance and did not perceive it as a purebred athlete. However, admiration has caused calmness and behavior on the most difficult high-speed maneuvers, even on bad roads. It is necessary to recognize that BMW kneeling, first of all, on American buyers for whom the car should be comfortable and especially fast on direct.

Unfortunately, the BMW 8 series debuted at a time when the world economy was only emerging from the financial world crisis, and the interest in luxury was low. For the new 840i in Germany asked for 130 000 stamps, and for 850i-180 000 stamps. Alpina B12 was worth more than 200 000 stamps. For 10 years of production was sold 30 621 copies. Thus, from the economic point of view, the project proved to be a failure.

History of BMW Series

Probably, this motto was guided by the supervisory board of BMW, when allocated a huge sum-1.5 billion stamps-on the project successor BMW 6 series E24. For such money, the car should be simply littered with the technique unused in any other model. In the end, it all happened. It was a demonstration of the skill and level of BMW. The couple cannot be denied elegance. The design was answered, with experience of working on cars with low air resistance. Today experts are more praising the pressure force than aerodynamics. However, in the 1980s the coefficient of aerodynamic resistance equal to 0.29 produced a strong impression. Devoid of any spoilers and diffusers the body has been thoroughly worked out for exposure to external flows and noise in the cabin. In particular, a large amount of work has been done to minimize wind noise in frameless windows.

The front and rear side windows can be completely hidden. Before opening the doors of the glass slightly descend. The coupe was equipped with safety belts integrated into the armchair. This system does not change the position of the belt relative to the body after seat adjustment. The work on the suspension, as well as on any other element, was very laborious. Engineers have created an innovative rear suspension with the name "axis-Z". The project was responsible for the division BMW Technik, which developed a similar system for the Z1 model. The suspension design is compact and efficient at the same time. The electro-hydraulic system of turning the rear wheels slightly changed the geometry, which led to a small turn of the wheels in the direction of rotation. This was against excessive understeer. The decision debuted in 1993 in the BMW 850 CSI.

Of course, the ESP system and traction control were not without. Adaptive shock absorbers and power steering are also used, changing the forces depending on the speed. An interesting feature-the use of a steering mechanism type screw-ball nut, the accuracy of which usually leaves much to be desired. A parking assistance system was also installed.

BMW 8 was tested in all weather conditions, which is not typical for Ferrari or Lamborghini. The latter feel uncomfortable in the city traffic jams or at high speeds in the desert. The "eight" experienced 50-degree heat with no problems, both under maximum load and at idle. The salon in any atmosphere cooled air conditioning to room temperature. Although BMW 8 was offered with a basic V8, the only correct engine is a V12. The engine with a working volume of 4988 cm3 carries the designation M70v50 and develops 300 h.p. it was established till 1992 in 850i and till 1994 in 850ci. These are the most popular versions of the model sold in the amount of over 20 000 pieces.

Engine BMW 850 CSI.

After 1994, the model 850ci got a modified unit m 73 in 54 volume 5379 cm3, developing 326 hp it silvered until the end of 1999. The mast-head became 850CSI with the engine s70b56 capacity 5576 cm3 and the return of 380 H.P., produced in the period of the 1992-1996 year. It is worth noting that M70b52 is one of the few components that has not been developed from scratch specifically for the 8-series. The motor debuted in the BMW 7-Series E 32, where it proved to be excellent. The big and heavy BMW 8 needed a powerful and lightweight unit. The best alternative than M70 simply was not. The motor weighed 248 kg and developed 450 nm of torque. Technically speaking, the engine was in a sense a combination of two 6-cylinder blocks. Each of the heads is provided with separate computers, which control the ignition and fuel consumption. Each head has its own throttle with electronic control, its own fuel pump and its own independent set of sensors. The block poured of aluminum, and in the noisiest places is provided with an insulating layer, suppressing sound. Double walls and noise insulation are present in the lid of the valves and crankcase. Even the cylinder liners on the outside have a special silicon layer that softens the vibrations.

The engine has an extremely soft operation. The launch is almost without vibrations, and on the running motor can build a house of cards. The idyll continues as long as the radiator fan is not turned on. Those who prefer the comfort offered a 4-speed machine ZF. For those who like full control is provided by the 6-Speed mechanics Getrag (standard in 850 CSi). It soon became clear that the manual gearbox was not in demand. Since 1993, each BMW 8 has been equipped with a 5-band ZF machine with the option of manual gear selection.
