The 525 Li is the entry-level seventh-generation BMW 5 Series launched by BMW Brilliance, which is a special model for China, and after the launch of the 525 Li, BMW canceled the 528 Li in the middle. From the outside, there is not much difference between the 525 Li and the 530 Li, you can choose between the luxury package and the sports package, the luxury package comes standard with ordinary LED headlights, and the sports package comes standard with follow-up headlights.
The 525Li is equipped with a low-power B48 engine with a maximum output of 184 horsepower, which is 40 horsepower less than the 528Li's 224 horsepower, and about 70 horsepower less than the 530 Li's 252 horsepower, and the 000 acceleration time has also changed from 6.3 seconds to 8.1 seconds in the 530 Li. ZF's eight-speed automatic manual transmission is still used, which has a very good reputation, and has a high level of matching with the engine, the gear change is very fast, and the smoothness of the gear shift is very good under the premise of sensing the shift action.
This generation of 5 series body uses a large number of aluminum materials, improve the rigidity of the body at the same time, reduce the weight of the car, this generation of 5 series of body in white is 50 kg lighter than the previous generation, and the chassis is also as much as possible to use aluminum, including the suspension of the front double wishbone, rear five links, brake calipers, the vehicle weight reduction of 130 kg, so even if the domestic sales of the G38 long shaft version of the wheelbase of 3108mm, the length of the vehicle is more than 5 meters, driving is still light. The rigidity and weight of the aluminum body are satisfactory, but the maintenance cost and maintenance difficulty are also much higher, and the A-pillar is too thick, and the blind spot is quite large, which is a potential safety hazard. The drag coefficient of this new body is also surprisingly low, the drag coefficient of the foreign G30 standard axle version is as low as 0.22, and the drag coefficient of the long axle version is also as low as 0.25, and the wind noise is also very subtle when driving at high speeds of 130-140Km/h.
The chassis of the seventh-generation 5 Series is very precise, the chassis of the whole vehicle is as flat as possible, very industrial aesthetics, the suspension system and brake system use a lot of aluminum material, the unsprung mass is reduced, the feedback is very fast, very high-end, the aluminum brake calipers on the Nürburgring performance is amazing, and does not show that the braking force is weakened due to thermal attenuation. Although BMW has balanced comfort and sportiness, and no longer has full handling like the E90, the limits of the entire chassis are very high, and it is difficult to push this chassis to the limit with at least 525Li's power.
The BMW 5 Series interior and configuration are luxurious, the soft materials are wrapped in a large range, and the whole design language is not as conservative as before, but compared with the Mercedes-Benz E, BMW still lacks a bit of texture. The operating experience of the iDrive human-computer interaction system has always been good, and the sixth-generation iDrive is also very easy to use. The 525 Li uses a full LCD instrument cluster, which was not available on the previous 528 Li. Inside, the 525 Li is made of Sensatec synthetic leather, which is also available as an option for Dakota leather.
The wheelbase of the standard axle version of the new 5 series has been 2975mm, close to three meters, so there is no need to worry about the rear seat space at all, and the knee room can easily reach two fists, while the wheelbase of the domestic long-axis version has reached 3108mm, which is better than the foreign standard axle version in terms of riding space, and the rear seat is equipped with Alcantara's headrest. The seat is stiff as always, the overall sense of support is better, the comfort will only be reflected in the long ride, the backrest can be adjusted relatively large, but mainly forward, backward even if it is put to the end, the sitting position is not very "lying". Because it is a rear-wheel drive model, the rear floor has a high bulge, and the center armrest of the rear row is stiff, so the center of the rear row can only provide a short ride. As for the trunk, because the suspension of the rear five-link takes up a large volume, even if there is no spare tire, the trunk of this generation of 5 Series can be said to be the smallest trunk in its class. Fortunately, the rear seats support reclining, although the left and right sides are narrow, but the space will still become a lot larger after folding.
The quality of the previous generation BMW 5 Series was unreliable and it was a car with a high incidence of breakdowns in all directions. According to the failure rate statistics of "Consumer Reports", the failure rate of major components such as the engine, gearbox, and circuit system of the 5 Series vehicles that are more than five years old is frequent, and problems in suspension and braking also occur from time to time. The seventh-generation 5 Series is completely reborn, too little to do with the previous generation, the reliability of the previous generation cannot be used as a reference for this generation of 5 Series, and there is no authoritative body that can endorse the reliability, and the expected reliability given by Consumer Reports is 4 out of 5.
The previous-generation BMW 5 Series participated in all IIHS basic items (frontal low-angle overlap collision, frontal medium-overlap collision, side impact, roof impact, headrest and seat) evaluation, and the frontal small-angle collision score was "acceptable", and the other scores were "excellent". The seventh-generation BMW participated in the IIHS test and received a TSP rating and a five-star rating in the E-NCAP test.
