BMW 7 Series

BMW makes changes and mechanical equipment in BMW 7 Series, and gives a different aspect, which somewhat resembles the Series 5. There are two forms of bodywork, the normal (5.03 m) and the long (5.18 m).

There currently is no diesel engines that are available with the long bodywork, but it will be soon available as the Diesel 6-cylinder (730Ld).

The most profound changes in this edition of BMW 7 Series are in the range of engines, where all those who had disappeared the previous BMW 7 Series, with the exception of the twelve-cylinder 760i.

A feature of almost all new engines is that they have better performance than the previous ones (greater power consumption and virtually the same or less), compared with versions that meet the Euro 4 emissions standard (not compared with Euro 3 engines).

All versions have a series of automatic gearbox six speeds, type 'Steptronic' without lever in the center console. To make changes by hand only has buttons embedded in the steering wheel rim. Another thing that has changed for the new BMW 7 Series system management and operation of "i-Drive".

The management system now includes the button that was first in the series, 5 and the structure is different menus and submenus. For example, it is now possible to directly elect the sound source.

There are changes in the standard and optional equipment. All versions have serial xenon headlamps, intermittent white lights and brake area varies depending on the intensity of the braking. The lighting system in curve remains optional. It is also standard equipment in all versions the automatic wiper. You can take receipt of digital and analogue television, and play CDs with songs in MP3 format.

The interior barely changed. There are some different materials, wood for example, now is hickory, and has expanded the range of color combinations to perform at ease consumer.

The plastic used on top of the dashboard is identical to the recently launched 3 Series. The 8-cylinder engine and 367 hp power of the BMW 7 Series 750i is very smooth at idle and in this car at least, very quiet any regime.

The strength of any engine is high speed and at almost any position of the accelerator pedal. As a result is less important not always being easy to choose the proper way when it chooses to manually change. The lack of a lever for change and with the buttons embedded in the steering wheel is not always easy to find the appropriate button to change.

The difference between stability of the long version of battle is clear and normal. Yet, surprisingly, the speed with which this can happen 'bus' with slow curves. It was a small note at the beginning of resistance will quickly turn if, because of the large wheelbase, but the car very well supported and once had begun to turn faithfully keeps track.

The rear measures 19 x 275/45 front and 245/45 x 19. As the wheel response is normal size range, with this definition spare wheel bearing evidence of our unity was the same size as the lead.

BMW has made several corrections in the rear suspension, which now have a 14 mm wider track. It has also increased the size of the brakes in some versions.

One of the most interesting changes is that BMW has simplified the supply of variants of suspension, which now have three alternatives instead of different combinations.

The three variants are a basic one called "Adaptive Drive", which differs from the basic wearing because the continuous variable dampers adjustment (EDC-K) and stabilizing active (Dynamic Drive) and a sport, with adjustments harshest to the docks, shock absorbers and stabilizer active.

From now on both the V8 diesel engine as the 6-cylinder in line are the engine block of aluminum, with shirts cast iron. With the use of aluminium, V8 engine weight is reduced to 30 kg and 25 kg of 6 cylinders, despite the increase in engine capacity.

Another important aspect in the new diesel engines is that the injectors are piezoelectric, which allows for more precise dosing of the amount of fuel injected and a better adjustment of the exact moment of injection. All diesel engines carry particulate filter that needs no maintenance.

BMW 7 Series

The BMW 7 Series 745d replaces the 740d. It remains a diesel V8 engine, but with 4.4 litre engine capacity instead of 3.9 litre. Here too there is a visible improvement in performance that consumption is lower.
