The protagonist of today's headlight test is the BMW 4 series, we got this 430i M sports obsidian suit model, in the narrow headlights, enough to accommodate two low beams, two high beam lights, a corner fill light and a laser light, really is a sparrow although small and complete. So how does this highly equipped headlight perform? Here's what we'll find out!
If in the F era, the difference between the 3 series and the 4 series is not obvious enough, then in the G era, the official also seems to have found this "problem". As a result, today's 4 series has also changed its face, and you don't have to worry about its recognition is not high enough. Of course, if you focus on the powertrain, you may not have enough of the difference that the official wants to convey, of course, you should not have driven these two cars.
Back to the point, today's content was originally a "standard" headlight test, but for the BMW 4 Series with some mysterious fun models, just to show everyone the headlights are afraid that everyone can't sit still, but it is not too necessary to take it out and do another period of evaluation, after all, this is not a new car. Then we will proceed synchronously, and the small editor of the car will save those useless nonsense and only talk to everyone about dry goods.
1. Headlight evaluation/function experience
2. BMW 4 Series experience feelings
Test model: 2022 model 430i M sports night suit Guide price: 448,800 yuan
Configuration: lamp source: far and near light are LED features: intelligent laser headlight adaptive near and far light
Lamp quotation: 430i M sports night suit with intelligent laser headlights, the price of a single lamp is 31,000 yuan, the quotation comes from the after-sales order price of the 4S store, that is, the price at which everyone buys a lamp. Compared to the 6 Series GT (32500 yuan) without laser headlights that we tested before, the headlights are cheaper, and honestly this price is not expensive. Of course, if combined with the price of the car, the zero-to-whole ratio is indeed not low.
I have to say that BMW's latest set of headlight designs is indeed very good in terms of recognition, and the visual experience is also very fierce. It is worth mentioning that the size of the 4 series of light sets is not large, but the sparrow is small and complete. The 430i M Sport Obsidian Suit models are equipped with smart laser headlights as standard, and their configuration can be judged from the blue trim in terms of appearance. Two low beams are located on the upper side, the high beam is arranged below the low beam, the daytime/width indicator is also very sharp, and the outer part is integrated with the turn signal function.
In addition, the innermost side is also equipped with fill lights, which can effectively supplement the light source on both sides of the front of the car, while the front fog lights are set in the position of the backflow port on both sides below.
Definition: When the luminous flux obtained by an object that is uniformly illuminated by light is 1 lumen on an area of 1 square meter, its illuminance (light intensity) is 1 Lux.
In the illumination distance section of the headlights, we take the brightness of 10Lux as the minimum illumination limit and take the distance value when this brightness is reached.
20cm is generally the minimum height of the front bumper of the vehicle from the ground, we choose this position as the lowest position of the light illumination, and the distance from this position to the headlights is the illumination distance.
The maximum distance measured by the BMW 4 Series low beam is 57.8 meters. This result is still quite powerful, you know, the farthest distance of the low light can exceed 50 meters, it can already hit the 85 points of the score, combined with the configuration of the 4 series headlights, it is also expected to be able to make such a result. However, the farthest area of the general low beam is usually the far right, and the low beam of the 4 series actually looks more uniform, and the lighting effect is ideal.
Then there is the high beam, the measured score of 93.3 meters is honestly average, not to mention the 122.9 meters of the 6 series GT, the Highlander we tested in the previous periods can also reach 100.1 meters, based on the 4 series of headlight configuration, in the high beam link can only hit a passing score.
After measuring the headlight illumination distance, we also tested the brightness of the taillights of the 4 Series. From the F era to the G era, BMW's tail lights have also changed their style, and many friends feel that the brightness of the tail lights has also been improved, which is indeed the case from the visual feeling. Normally, the brightness of the taillights exceeding 50lux is relatively bright, and 91lux is even a bit dazzling in dim conditions. In addition, the recognition of the taillights of the 4 series is also quite high, close to its own big brother 8 series.
BMW 4 series headlights, when unlocking the door with the key, the width light will be gradually lit first, at this time the headlights will slowly adjust upwards and light up, and the car will bring a certain sense of ceremony at night.
First of all, the model with laser headlight configuration, although the lighting effect after opening is very powerful, but the function is difficult to be turned on. Turn on the laser headlights to meet three conditions, the first is the automatic headlights / adaptive mode open state, followed by the surrounding environment is dim and there can be no light source in front, and finally the vehicle to reach a certain speed, BMW's laser headlights need to be more than 40km/h per hour to turn on.
Based on the above, it is basically impossible for laser headlights to be turned on in the urban environment. Even on highway sections without street lights, it is difficult to turn on laser headlights, after all, it will involve the light source brought by the target vehicle.
So since laser headlights are difficult to turn on, why do you need this configuration? First of all, laser headlights, as a more advanced configuration, are only equipped on some models with relatively high prices, and the price of optional equipment is relatively expensive. But when you have seen the performance of the laser headlight after it is actually turned on, you can understand why it is expensive and why it is difficult to turn on.
The above figure is very intuitive, after the laser headlight is lit, it is a small range of "cylindrical" or "spot", that is, it does not increase the lateral illumination range, nor does it increase the brightness of the existing illumination, but there is only one more lighting area at the farthest distance. In order to achieve an irradiation distance of several hundred meters, the brightness of the laser headlights is very strong, and the illumination angle is almost parallel to the headlights, if it is illuminated to the human eye, the light will produce dizziness, and the heavy will cause irreversible damage to the eyes. Here, Xiaobian definitely does not recommend that you change such a lamp yourself.
Therefore, there is a reason why the opening conditions of laser headlights are extremely harsh, in order not to cause harm to the outside world, all models with laser headlights do not support manual opening mode, avoiding arbitrary use. Having said that, in the actual domestic car environment, laser headlights are still a relatively chicken configuration in the end, but most models with laser headlights look better, which also attracts everyone's attention. As for whether to choose or not to choose, do you regret not having this configuration? Xiaobian's suggestion is to look good and not to be bad money, for the actual experience is not necessary.
The emergence of the adaptive far-beam function is necessary because it not only corrects the error of using the high beam in violation of the rules, but also reduces the number of steps for the driver to manually turn on the high beam. You know, we now need to use the high beam for a long time the scene is less and less, driving in the road conditions without street lights, the probability of encountering the opposite car is also relatively high, so turning on this function also saves the driver a lot of trouble. Of course, whether this feature is good or not is very important.
At 30km/h, the high beam is automatically turned on according to the environment in front, and the high beam is automatically turned off when the speed drops to 20 km/h.
To be honest, the last test of the adaptive far and near light function of the 6 Series GT did not leave me with any good feelings, because in the adaptive mode, the conditions for the high beam to be turned on were very harsh, and it was almost necessary to encounter no visible light to activate the high beam, which was more obvious in the high-speed section of the road. Switched to the 4 series, the actual experience is much better. In adaptive mode, the camera is very efficient in turning on the high beam in the real-time environment in front of it, and there is no phenomenon that it is difficult to open. And the high beam can be lit in sections, in urban areas, even if there are street lights, some dark areas, such as sign lights, will be illuminated individually.
1. This 4 Series and 3 Series have different driving experiences
Regarding the appearance, the 3 series and 4 series are differentiated, I think everyone is not entangled, a sports car and a coupe. The difference between the two cars goes far beyond the design level. Compared with the 3 Series, the 4 Series body height is 57mm lower / the center of gravity is 21mm lower / the rear track has increased by 23mm, for these three sets of data, it can also be seen that their properties in terms of handling are still somewhat different, the focus is that the suspension /steering adjustment of both cars has a certain change.
Friends who have opened the standard axle 330i will definitely feel that the sporty adjustment of that car is more distinct, of course, the intuitive feeling is still not comparable to the F generation model. The tuning of the 4 Series from the chassis is closer to the F-Generation model, and it is said that it is not as comfortable to drive as the 3 Series. In contrast, the 4 Series in everyday driving, the suspension will appear tougher, giving you a stronger sporty attribute. Our test drive is a big fully equipped, M sport suspension, variable steering ratio, front four-piston brake caliper and rear axle limited slip differential, of course, many of these are optional, so here Xiaobian will not describe too much for these configurations, in short, there is no money is not spent.
In the original factory state, although the power parameters of the 3 series and the 4 series are the same, the measured acceleration of the 4 series will be lost faster. (Half a second less) About 6 seconds of acceleration to put into daily driving is enough, no need to say almost meaning, after all, it and the properties of the steel gun are different, there is this idea can go to the price of M2. However, to be honest, the somatosensory acceleration of the 4 Series is not strong, which is mainly related to the better sound insulation and more conservative mechanical sound of this generation. In addition, in addition to the moment of starting, even in the strongest mode, you don't expect the original exhaust to have any echo with you.
In terms of somatosensory acceleration, there is basically no difference between the 3 series and the 4 series, at least the small editor did not open it. The absolute power of the 430i is enough for a coupe, especially the staying power, which is super unconsciously: (You know) I also experienced mountain driving accordingly, and if you look at it with the attitude of a sports car, the 4 Series performs well in the multi-curve section, and the limit is quite high. If you look at the standards of sports cars, find out if the brz that has just been listed can be licensed in your area.
2. Daily car experience
Although the tuning of the 4 series mentioned earlier is more radical than the 3 series, but the daily transportation is not a sense of violation, the above sports attributes can not be too involved in comfort, or that sentence, do not think of it as a sports car.
I strongly recommend that you buy the 4 series do not consider the 4-door version, the essence and selling point of the 4 series comes from the coupe body and the two-door design, and it is precisely because of this that the return rate of this 430i is not low, just like many people who encounter MINI will unconsciously look at whether it is a little sister to open another reason. If there is a need to use the back row frequently, it is better to spend less money to buy a 330i.
The characteristics of the low center of gravity of the 4 Series can be experienced from the boarding process, which is not comparable to a sports car, but it is also quite low. Every time I get on the bus, it's fine, there is no feeling of sitting in the "pit", the words when I get off the bus are not very elegant, I am used to weighing the threshold with my hands. M sports seat style is good-looking, wrapping and not to be picked, but to be honest, the comfort of this sports seat to sit up is definitely inferior to the 3 series, of course, want this discomfort to spend more than 9300 yuan to choose.
In fact, the practicality of the two-door version of the model is not bad, of course, this is combined with the positioning of the coupe. The wheelbase of the 4 Series is 2851mm, the C Coupe is 2840mm, and the A5 Coupe is 2770mm, so the 4 Series is the most stretched and has better space. The space in the back row is sitting people and putting things are no problem, the actual measurement of my own height of 180cm, sitting in the back row does not prostrate the head and do not top the legs, is the posture of getting on and off the car is indeed not very good-looking, try to let the elders sit in the front row.
In summary, let's talk about it in two ways. First of all, combined with the price point of the test model, the price model can use laser headlights as standard, which is worth praising. Then the actual performance of this headlight is not bad, the low beam over 50 meters can score high, but the performance of the high beam is slightly weaker, and the adaptive far and near light function is also very good, in line with its positioning named after intelligence.
So about the purchase suggestions of the 4 series of this car, Xiaobian believes that if you feel love at first sight about the design of this car, then it is good to pick the configuration in combination with the budget. If you have some concerns in the budget link, then in fact, the 425i model is also worth recommending, after all, the reason for buying the 4 Series is because of its style, and the performance is only an accessory. If you are struggling with the same level of models at the moment, then the current 4 Series product power must be the highest, after all, it is newer than the opponent. However, it may not be the current market of the 4 Series, there is no preferential price increase and you still need to wait for the car, which is also testing whether it is your true love.
