Test Drive BMW 7 Series F01-02 Restyling since 2012 Sedan
It's finely noticed!
Ralph Villems that responds to BMW for the technology of reducing fuel consumption Efficient Dynamics, enthusiastically tells me about the work done. It takes an hour, and already chassis Albert Mayer intercepts the relay. The reason for this conversation was to update the flagship of BMW BMW 7th series. You need to get acquainted with such a car from the rear seat, I thought, and was located on a stunning sofa of the long-base 750Li, molded strictly for two passengers. A colleague, who became my personal driver on the route from the famous Komarovo in the vicinity of Peter to Catherine Palace, kindly pushed the right front armchair to stop forward. Thanks to a huge range of adjustments, I turned into a comfortable layer and now with the help of the rear joystick of the IDRIVE information system wandered around the car menu, looking at the 9.2-inch monitor, as if soaring near the back of the front armor is luxurious, nice, Functionally.
Suddenly, an unpleasant boom is distributed in the rear axle area. I look out the window and see that we are going along the road made of huge concrete slabs, and on every junction the suspension works quite rigidly. It's all about the so-called Run-Flat tires with rigid sidewalls, they allow you to drive about 150 km at a speed of up to 100 km / h in case of puncture. According to the Gerra Mayer, in cooperation with shinniki, they put a lot of effort to reduce the negative impact of the Run-Flat on the smoothness of the stroke.
Now the rear suspension subframe is attached to the body through hydraulic supports, and pneumatic bullons will be used on all modifications of the seven as elastic elements. The upper support of pneumatic racks made a little softer, and the damping coefficient of shock absorbers, on the contrary, slightly increased. In addition, the chassis software, including the optional active-twisting rear suspension, active stabilizers and shock absorbers with continuous separation adjustment of the abdomen and compression, finalized with an emphasis for greater comfort.
I transplant to the driver's seat and mark all the same crystal clear steering wheel with a clear effort. Albert Mayer says that this is a special BMW chip and they managed to keep it and after installing an electromechanical steering amplifier. However, it was possible to introduce it not on all models: all-wheel drive versions of the seven will still be equipped with hydraulic plates to find a place in the open space only the question of time.
The 8-speed ZF automaton, from now on, installed on everything without exception, the seven, depending on the selected vehicle mode, it works or very smoothly and prefers enhanced programs, or the tachometer arrow stands up and pulls the steps. In addition to the nature of the KP, Eco Pro, Sport, Sport + and Comfort modes, change the response of the gas pedal, the efficiency of the steering wheel, the operation of the suspension and the engine. With an active-piring rear suspension, a special Comfort + mode is available.
At any speed in the cabin, it is very quiet, not in vain Ralph Villems and its engineers spent a lot of time in an acoustic laboratory and an aerodynamic pipe. The brake of the 7th series should be accelerated powerful and efficient. With a fully pressing accelerator, a pleasant metal rocometer of the 449-strong burgot-eight comes to you only closer to the red zone of the tachometer, and kilometers per hour are gaining very rapidly, and there are still 760i with 544 horses under the hood. But it was not possible to try it on the presentation only the 750s.
BMW does not conquer not so much with luxurious and powerful machines as constant improvement, an increase in efficiency and fine tuning of all car systems as a whole. For example, to reduce fuel consumption, all pumps have a variable productivity: oil, coolant and even hydromoline in the active stabilizer system. This is also needed to add controlled blinds in the radiator grille and operating mainly on the braking generator.
It is thanks to such a fine work, the bmw seven has become expressive, safer and even more powerful without losing economy.
