Written on the front: to see the configuration and rear knee space with a few punches please detour, we only talk about data. Netizens who want to see relevant competitive model data can search for "Lab test brand models" to compare themselves - for example, search for "Lab test Audi A6L" and "Lab test Mercedes-Benz E-Class"... If you can't find it, it's Bogo I haven't measured it yet!
It is said that consumers who buy BMW never read any BMW-related evaluation articles, and they do not care about any sheet metal process and car paint. According to the results of the research results of bmw brain fans around me, they first care about the car logo totem, the second cares about the official power data, the third cares about whether the engine sound wave is louder than the Mercedes-Benz Audi car, and the fourth is worried that the maintenance price and fuel consumption are lower than the mercedes-Benz Audi class of cars... And they don't even care if they have turn signals... Still, Bogo wrote this article for people who couldn't afford a BMW or couldn't.
The model we tested this time is the BMW X3 2022 xDrive30i Premium M Yao Night Suit, the official price is 475,800 yuan. And to Bogo's surprise, this car will only be available in 2021, and now it has been discontinued! In its place is the "BMW X3 2022 revamped xDrive30i Premium M Obscurity Suit", the official price of 479,800 yuan - see? There are more words "revamped".
So what's more after the change? One more front-row phone for wireless charging. That is to say, a front-row mobile phone wireless charging is worth 4,000 yuan ... This sentence is according to the tone of BMW consumers, I am afraid it should be said: a front-row mobile phone wireless charger actually sold 4,000 pieces...
This IQ tax is not high.
For the sake of narrative convenience, the test car is referred to as the "X3" below. As usual, it is emphasized that due to the difference in vehicle conditions, road conditions, humidity, temperature and surrounding environment, data such as acceleration, braking, handling, true endurance and silence test are for reference only and cannot be used as an objective basis for comparison.
The whole test process is presented in the form of video, but in order to meet the needs of those who do not have money to buy traffic or do not have time to watch videos, so we still show the test data below. (Video stamp at the beginning)
Sheet metal process 95 points
The sheet metal gap measurement points we selected on the X3 are 4 pairs of 8 groups, which are the left and right gaps between the hood near the lower end of the A-pillar, the left and right gaps at the front of the hood near the headlights, the left and right gaps at the upper end of the tailgate near the windshield, and the left and right gaps at the lower end of the tailgate. Basically, this set of data can reflect the overall sheet metal process of this car.
In our test system, 100 points is called perfect, 95 points is called excellent, 80-90 points are qualified, and manufacturers below 80 points need to think behind closed doors. Since the hood and front fender are aluminum alloy, the X3's 95 points are really rare, after all, the stamping assembly process of aluminum alloy sheet metal is difficult to be above ordinary iron sheet metal.
The paint spraying process involves being spanked
Since the hood is the largest sheet metal surface of the car, we specially selected 6 points on the X3 hood for paint thickness measurement. Basically, this set of data can reflect the overall process level of X3's car paint.
Obviously, the two sides of the folding edge spray painted too thick to pull the hind legs - in our system, the spray accuracy square difference of ≤ 50% can be called perfect, ≤ 150% can be considered excellent, ≤ 400% qualified, more than 400% to be spanked. Well, now the car can be towed down and spanking!
Dynamic tests can't pick out the bones
The X3 has a curb weight of 1600kg and is equipped with a 2.0T in-cylinder direct-injection in-line four-cylinder engine, mated to an 8-speed automatic transmission, and has a maximum output of 185kW/350Nm. The test road conditions are the standard straight paving standard for China's first-class highways, the temperature on the day of the test is 29 °C, and the test altitude is 1300 meters.
The 8AT transmission has a large torque output against torque, and for a 2.0T gasoline car, the maximum acceleration force of 0.774G is quite high in the same class. The fastest speed of 0-100km/h is 7.02 seconds, which is not bad compared to the altitude of the 1300-meter test section, after all, the official result is 6.80 seconds.
The best time for the five 100-0km/h brakes was 36.81 meters and the average was 37.39 meters – this set of data is quite impressive, which can be called a performance-level performance, which is significantly better than the average brake data of the X3 segment last year. In addition, the brake thermal attenuation is also impeccable, and the score of 15.19% is perfect - according to our classification, the square difference of brake thermal attenuation ≤ 25% is perfect, the ≤ 50% is excellent, and the ≤ 75% is qualified. From this point of view, bmw X3 is worthy of the golden sign of performance.
Many people judge the handling of a car by the softness of the suspension. In fact, there is no absolute correspondence between the handling of the vehicle and the softness and hardness of the suspension. At present, the FIA uses the maximum acceleration of the cornering centripetal force , also known as the "G value", as the only measure of vehicle handling. Today's F1 racing car, its cornering handling limit can reach 6 times the gravitational acceleration, that is, the level of 6G, and the control limit of ordinary grocery shopping cars is also around 1G.
There are many factors that determine the handling of a car, such as the maneuverability in the pendulum state, the high-speed tracking of the rear wheel, etc., the horizontal G value is only one of them, but the G value is currently collected and the control is directly related to the control, and the objective data that is least affected by the quality of the driver - we can regard the horizontal G value data as the college entrance examination score under the test education, although it cannot fully reflect the comprehensive control quality of a car, but the good guys can see the high and low through a standard score. This is why the FIA is accustomed to using the Skid Pad transverse G-value rather than the elk test to reflect vehicle handling.
X3's 1.279G extreme control data is a fairly high score in our test history, notes last year's "Lab test" of the "control king", also ran out of 1.200G. Although this data is pushed out by ESP, it is undeniable that if the chassis is too poor, ESP will not be able to push the X3 to the height of 1.279G even with the strength to suckle – this data is significantly better than the average performance of the X3 segment last year.
Checked, this car is still equipped with a Bridgestone proud ALENZA A001 tire that is not known for extreme handling but pursues comfort, if you change the sports tire such as Bridgestone Botian, the control limit may be able to pull up. To be honest, today's BMW 3 Series sedans are becoming more and more "Mercedes-Benz", and they have been unable to run such control limits since the previous generation.
There is also a meaning, that is, the X3 rear wheel size 275/40R20, which is much wider than the front and back of the 245/45R20, but the e-commerce price is much cheaper than the front wheel.
The engine vibration test was quite good
We turned off all the electrical systems that could be turned off on the car and tested the X3's maximum engine amplitude in the hot car idling state , 0.025mm , which was a pretty good result. After all, in our test history, there have not been many cars with a maximum amplitude of less than 0.040mm for a hot car idling engine.
The maximum amplitude of the steering wheel in the hot car idling state is 0.008mm, which can be rated as excellent. By our standards, this figure ≤ 0.005mm is perfect, ≤ 0.010mm is excellent.
Mute performance is poor
Under the premise of turning off the entertainment system, air conditioning and car windows, we selected the flat pavement standard of China's first-class highway paving, and tested the in-car silence of the X3 at 40km/h, 60km/h and 80km/h at uniform speed.
Given the body structure of the X3 "front aluminum rear steel" (the hood, front fenders and front side doors are all made of aluminum alloy), we were not optimistic about the silent performance of the X3 before testing. Compared to the average silent performance of the X3 segment last year, this set of data for the X3 is actually not good.
But it doesn't matter, after all, BMW consumers don't want the car to be too quiet, don't they?
Many readers have asked us why we do not measure the 120km/h interior silence. The reason is simple, that is, the conditions do not allow it. Our test standard is that on the straight and dry first-class highway paved road, the driving vehicle maintains a corresponding uniform speed for 30 seconds, with the lowest noise value measured as a result, the road cannot go uphill during the test, and it is also necessary to ensure that there are no cars within 30 meters of the body. So, 80km/h is already our test cap.
So, please also ask some keyboards to accumulate virtue, you see the article is a matter of minutes, but our test will take at least a day's time, the most tragic is the summer, because the acceleration and mute test process is not allowed to open the air conditioning in the car, but also have to close the window. Please believe a little, but when there are conditions, we will not let go - do not believe please see the picture below.
