[YesAuto evaluation] We make a living by testing new cars, but it is rare that all test cars of the same car series and different displacements are present. For example, this time the BMW Brilliance X1 has three units, namely 18i rear-wheel drive luxury, 20i four-wheel drive luxury, and 28i four-wheel drive luxury. This car has just been on the market for more than a month, and some can already be seen on the street. There is no mark on the displacement on the bottom of the car. The 18i is stunned, the 28i is uneven, and the 20i is the most calm.
Historical experience tells us that every change is accompanied by pain. The BMW N20 series 2.0T engine replaces the straight-six self-priming change, not only for today's X1, but also for the future 3 series and 5 series. For most people, in addition to emotional nostalgia, there is also auditory loss. You have to learn to get used to the diesel-like clicking sound when idling. This is even nicknamed a pedestrian reminder system. A few people can still feel it. There are some differences in ride comfort. In addition, the combination of 2.0T and 8AT seems impeccable. Let's talk about it in detail below.
The 2.0T of the N20B20 uses almost all of BMW’s advanced engine technologies, including TwinPower single-turbo twin-scroll turbocharging, Double-VANOS dual camshaft variable intake and exhaust timing, high-precision direct injection, etc. So the book data you see is very amazing. The low-power version of the 20i is 184 hp/270N·m, and the high-power version of the 28i is 245 hp/350N·m. This makes the data of the traditional 2.0 naturally aspirated engine of the 18i inferior. : 150 horsepower/200N·m.
The X1 is also quite generous in terms of gearbox, using ZF’s 8AT, which is currently the top configuration on the market. It is lighter than the 6HP28 (ZF second-generation 6AT), and the torque limit is close to 700N·m. The shift speed 200 milliseconds, in the congested road conditions in large cities in China, it is more reliable than the squeamish dual clutch. The electronic gear has a good grip, but the 18i can only be used with a mechanical handle because it is equipped with a 6AT.
Looking at the actual results, the following are the 100 km acceleration test results of the three cars. The 18i of the rear-wheel drive took 11.26 seconds, and the 20i and 28i of the four-wheel drive took 8.08 seconds and 6.82 seconds respectively.
Despite the ordinary parameters of the 18i's 2.0-liter engine, the explosive power at the start is considerable. Due to the rear-drive transmission mode, the rear wheels will slip slightly. After the tires regain the grip, the acceleration G value drops a lot. The progress of the vehicle is smooth and flat. 11.26 seconds is slightly slower than the official score, which is acceptable.
The four-wheel drive version of the 20i is more robust. The tires stick to the ground and start smoothly. The highest G value climbs to an astonishing 0.892g, a figure that can only be seen on a performance sports car. It can be seen that the G value curve fluctuates significantly in the second half, and the smoothness of the power output under high load conditions is still different from that of naturally aspirated. The final score was 8.08 seconds, which was in line with expectations.
The much-anticipated 28i came out. Its fastest acceleration time is 6.82 seconds, which indicates that the two-liter displacement supercharged engine has entered a higher level of performance. In addition, you can also estimate the new generation of the rear-wheel drive version. How fast can the 328i run. This engine maintains a strong power output throughout the entire range of 1st gear. After shifting to 2nd gear, the situation has not dropped particularly much. Perhaps you will now understand why BMW dared to let the straight six self-prime and retire, 2.0T+8AT. The combination of at least does not lose to the predecessors in terms of accelerated performance.
The braking results of the three test cars are very satisfactory, all of which are of excellent level. The braking system is in place, and the strong support of the suspension also allows the body to maintain a better posture. The 28i uses a 255-width rear wheel, so the results are better than the 18i and 20i. From this perspective, the quality of the X1 is not inferior to that of a sedan.
The most obvious shortcoming of the N20 series engine is that the sound is loud at idling speed and it sounds like a diesel engine. Fortunately, it has the help of 8AT after running. The speed is very low, and the noise level of each speed range is fairly controllable, and does not affect the senses of the passengers in the cabin. Feel.
After reading the performance test results, let's talk about the driving experience of the three cars. Recalling the 18i, the steering wheel feel is the first one that comes to mind. It uses mechanical hydraulic assistance, and the feel is very heavy. Yes, I mean it is very heavy. It is heavier than the impression of BMW in your mind. Unless you have practiced it, it will be difficult. For sure, it's a lot easier to open the 20i and 28i electric boosters again.
No matter what V is classified as SAV, SUV or S, the slender X1 does not provide much higher sitting posture than ordinary cars. The chassis suspension and steering performance are in the combined zone between urban SUVs and cars, while borrowing Some people say that the X1 is a heightened 3 series. It is not impossible to understand it. However, unlike the 3 series, this product has a four-wheel drive version, which is not as sharp as the 3 series in terms of control. You don't have to worry about the muddy car that the car can't get through. What's more, you can also enjoy the handling close to the car on the urban paved road.
Speaking of the driving method, these days have basically been driven in the city. During the test, except for the staking site, it is difficult for us to intuitively understand the difference between rear-wheel drive and four-wheel drive. I think unless it is a northern user, this is not necessary. Issues being considered. Make good use of the X1's higher body and don't even think about going off-road, that's enough.
The difference in power between the three cars is obvious, and the previous test data is already clear. The 18i naturally aspirated engine can deal with a heavy body of more than 1.56 tons. It is not weak, but it is difficult to perform well. This personality is very suitable for pure household needs. It does not pursue other things. It is just for the classic BMW driving atmosphere. The steering wheel and pedals are all soaked. In the thick sludge, it is comfortable and comfortable.
The 28i is quite refreshing. The complex technology makes the peak torque appear early. If you step on the accelerator slightly, there will be continuous power overflow. If you want to make a big splash in the three cars, you can only rely on it; the low-power version of the 20i engine The output is moderately adjusted. Compared with the 18i, it has made epoch-making progress. It is not too brave like the 28i. If you live in a city, this level is just right.
Suppose you are a perfectionist, and you have the opportunity to put these three cars together like me, you may notice the small flaws of the 20i engine: the 28i high-power version 2.0T replaces the imported 28i high-power version 3.0 straight six It can be said to be conscientious, and the low-power version of 20i 2.0T still has a gap with the imported 25i low-power version 3.0 straight six in terms of smoothness. Its hesitation in the low-speed range can be felt, but for ordinary consumers It's not a big deal, the problem can be solved by a little deeper throttle at the start.
The 8AT gearbox is an air-like existence, but when there is it, it is only so, and when it is not, it can immediately feel the difference. The daily driving is quiet and smooth, and the accelerator can jump from 8th to 2nd in an emergency. It can be described as both civil and military. It is worth mentioning that in the acceleration performance test, it did not repeat the violent upshifting sense of the domestic Q5 (click to view), which is very gratifying. As for the 6AT on the 18i, it is actually very competent for daily use, but if you are used to using electric lights, who will miss candles?
The BMW Brilliance X1 combines the versatility of a city SUV with the driving pleasure of a car, and at the same time it reserves enough ride comfort. According to the classification, its rival is only the Audi Q3. I have tested both models. (Click to view the imported Q3 test drive article), frankly speaking, due to the different personalities, the possibility of a head-on confrontation is unlikely, which is good news for both parties.
Yesterday we released a domestic X1 car purchase manual (click to view). It is recommended to buy the 18i luxury version. First of all, there is no problem with the daily use of the power. The 2.0-liter self-priming engine is in line with the feeling of living at home regardless of the torque performance and the smoothness of the power output. Although the 6AT gearbox of the mechanical shift lever is far worse than the 8AT, it is also an excellent configuration in the same level. Of course, the most important thing is the price of 319,000. As for the problem of rear-wheel drive and four-wheel drive, if it is not for northern users, there is no need to entangle it. These days of testing can only see the difference on the staking field.
Having said that, if the budget is large enough, 20i can better reflect the power of technology. I personally think this is also worth recommending. The combination of 2.0T+8AT is undoubtedly the most advanced configuration in the same level at present, and it is in the increasingly stringent EU emission regulations. Under the circumstances, BMW used this solution to actively respond, and at the same time, it can also meet the needs of consumers, which can be described as killing two birds with one stone. At the end there is 28i left, which is left to the gold family. Let us end today’s article in 6.82 seconds of violent acceleration. Please also remember this number. At present, it represents the new height of 2.0T engine among ordinary household models. Also look forward to the new generation of 3 series can have a stronger performance.
