VF-Engineering chose to supercharge the BMW E38 740 to increase throttle response and mid-to-top end power with the centrifugal Vortech supercharger. With the stock 4.4 liter motor, power and torque are already suitable for the heavy 7 series chassis. However this upgrade is for the V8 enthusiast who demands more power. The new found power makes the E38 740 powerful enough to overtake and accelerate hard with the greatest ease. As a daily driver the supercharged BMW 740 is a mild mannered executive car waiting for the throttle body to be flung open. It is easy to slide the back out under full throttle and send the 7 series V8 to ridiculous speeds way above the limit. Upgraded brakes are a suggested pre-requisite.

Both the E32 and the E38 7-Series can suffer from the dreaded 'shimmy'. This is wheel-wobble that usually first shows itself under braking, for instance, when coming off a motorway intersection and braking from high speed. The wobble can be felt through the steering-wheel but it usually disappears as the car speed reduces.

Sometimes this is all you ever get, but more usually you will start to get wobble as the car is accelerated through 50 - 60MPH. The more you drive the car the worse it will get. The wobble is quite often accompanied by tram lining and a general feeling of imprecision from the steering in general.

The shimmies are often an indication of general wear in the steering system and suspension, the BMW E38 has a great deal of weight over the front wheels, especially when braking. It also seems to have a resonant frequency that occurs between 50 and 60 MPH, if there is any weakness it is at this speed where the problems will occur.

BMW F01/F02 - a wreath of creation of modern engineering thought. In this car all modern technical novelties have united. Many of them are applied in motor industry for the first time. For example, it-lajn technologies - in the car is available constant access to a network the Internet.

The modern design of the new seven does its by one of the most beautiful models of the company and shows what lines the future models of mark BMW will possess.

New BMW 7-series is the leader in a segment of representation sedans and a mark leader. Compete with it the Mercedes-Benz a S-class can only.

E32 Became the second generation of a 7-series. The car has shown all achievements of mark BMW of that time and has set a new course for other manufacturers. For the first time on the car of such class engine V12 has been established.

The new model differed high quality of assembly. Thanks to it and the hi-tech engine in interior it was not audible noise.

The first had been presented model 735i which had in-line 6 cylinder engine M30 capacity of 220 h.p. the Following seven was extended on 100 mm. Model 735iL. The car strongly differed from the predecessor. Devices became more convenient, the panel of devices is more ergonomic.

In 1987 versions 730i, 750i and 750iL have been presented. Cars with engines of 3 and 3.4 litres were completed 5-step mechanical and 4-step automatic with transmissions. On cars with engine V12 put only "automatic machine" with an electrohydraulic control.

BMW E38 - the new leader of the company which have come in the stead E32 in 1994. The design of the new seven was in many respects defined by the previous model, but E38 became even more comfortable. Exclusive models 740iL and 750iL have extended on 140 mm. Base, and version 750 XLA on 390mm. Armour versions of the seven Also were issued. In the end of 1998 the model has undergone to small restyling.

There have been five generations of the 7 Series BMW:

* BMW E23 (1977–1986)
* BMW E32 (1987–1994)
* BMW E38 (1994–2001)
* BMW E65/E66 (2002–2008)
* BMW F01 (2009-present)

The E38 BMW 7 series sedan was introduced to the US market with the 1995 model year last year of production was 2001. The E38 was considered to be the best seven series produced by BMW thanks to it’s flawless design and amazing character, this vehicle was truly a grown up luxury sports sedan with it’s driver oriented interior and amazing handling mixed with perfect luxury.

BMW offered two versions the i - short wheel base and the 6” longer il versions. The il is easily recognizable of it’s long passenger window. For the US market two engine variants were offered the 4.4 liter V8 in the 740i and 740il and the 5.4 V12 engine in the 750il, the V12 was never offered to US customers with the short wheel base version.

The last 740d was a 4.0 V8 diesel. Confusingly to
people outside BMW, the new 740d is not a V8, nor a 4.0-litre. Ah. Nope, the
new biggest diesel in the 7-Series range is a new super-efficient twin-turbo
straight-six, and it's a 3.0-litre block, but this time not derived from the
same 3.0-litre motor that you find in 30d and 35d versions elsewhere in the BMW
ranges.

Still with me? Right, explanation ahoy: this new
motor gets an all-aluminium crankcase and third-generation, common-rail fuel
injection that's good for 2,000 bar of pressure. Piezo injectors provide the
injection, and big pressure and fine control are good things. Higher pressure
means bigger bangs, control means more efficient burns, the pair bring better
power and economy.
