[YesAuto Review] BMW named their top flagship 7 Series. The number “7” is very mysterious. For example, a person has 7 orifices, 7 days in a week, 7 colors of a rainbow, 7 continents in the world, and so on. In addition, it is said that the short-term memory of ordinary people has only 7 capacity units, and it is easy to forget if it exceeds this limit. The most interesting thing is that no matter how big a piece of paper is, it cannot be folded in half more than 7 times. In addition, there are many stories about “7”. Especially in Western concepts, this number seems to contain some eternal truths, representing perfection and ultimate.

Now let us turn our eyes back to this car. The current generation of BMW 7 Series belongs to the fifth generation of the family. It was born in 2009. The 2013 BMW 7 Series is a mid-term facelift and was launched at the end of 2012. The test is the 2013 BMW 740Li xDrive, equipped with a 3.0T engine and four-wheel drive system, and the manufacturer’s guide price is 1.328 million.

The appearance of the new 7 Series is not significantly different from the old one, mainly due to minor changes in several details. This 740Li xDrive model is not equipped with the full-LED headlights on the 2013 740Li luxury model. It only uses LED fog lights and rear-view mirror turn signals. It looks nothing special.

In addition, in terms of size, the slight changes in the front and rear body surrounds have resulted in a nearly negligible increase in the length of the body. Its length, width and height are 5223mm, 1902mm and 1498mm, respectively, and the wheelbase is still 3210mm.

The four-wheel size is the same 245/50 R18, which is the same as the two-wheel drive version 740Li. The tire of the test car is Pirelli P ZERO, which has higher specifications than the German Continental ContiSportContact 3 common on other 7 series. However, in the same model that we have photographed before, we have also seen the phenomenon of Dunlop tires. Later, I consulted the BMW 400 customer service hotline. The official explanation is that due to different production batches, the three brands of tires may appear, and their performance is fully up to the requirements, do not worry about this, it seems that if you have a preference for tire brands, I am afraid Only by luck.

The rear styling is also very concise, with only an unobtrusive chrome trim strip added. Finally, in order to make it clear of his four-wheel drive identity, this car added a “X DRIVE” logo on the upper left of the rear.

Up to this point, there is nothing else worthy of a book about the appearance. The focus of improvement of the 7 series is not here. After all, it is important to keep a low profile and steady for a luxury car.

The interior is the same as the 2013 740Li leading model, with a variety of black leather on top, dark piano paint wood grain decorative panels and inlaid silver decorative strips. The elegant elements are complete, and the lines and layout follow the original design. The decent luxury style.

Key improvements: the third-generation BMW iDrive system

The main difference between it and the old interior is the enlarged central LCD display-the standard equipment of the new third-generation iDrive. The biggest advancement of the new system is the addition of the “BMW Connected Driving” concept.

The so-called connected driving can be simply understood as adding network interconnection technology on the basis of an integrated operating system to realize various information exchange functions and connect the driver, the vehicle and the world outside the vehicle.

The hardware of the system also includes a new iDrive control knob (iDrive Touch Controller). The middle of the knob becomes a touchpad. You can write on the board when you enter the navigation address, but I want to use this small circle with a diameter of only 45 mm. It takes some time to get used to writing on the disk.

In the Chinese mainland market, China Unicom provides 2G and 3G mobile network services for the system. A non-removable China Unicom 3G SIM card is built into the vehicle when it leaves the factory to achieve network interconnection functions, such as remote after-sales service and real-time road conditions. Information, Baidu map search, journey consultation and information online, etc.

From the actual experience, real-time traffic information is the most practical everyday for drivers, so you don’t need to take out your mobile phone to check the traffic. The online information function is also good. There are weather forecasts, news and stock information, etc., so that the rear boss can pass the time in the car, but occasionally encounter signal problems during the driving process. People who have used China Unicom’s 3G network should be able to understanding.

After a series of practical experience, “Connected Driving” is the most significant concept innovation of the third-generation iDrive. It is a standard feature of all 7 series, but there is still room for improvement in use.
