In 2021, when doing the two-vehicle durable road test, I met a camouflage car on a highway by chance, and the words "electric test car" were written at the front door.
From the front face of the fully enclosed double kidney grille and the shape of the daily running lights on both sides, it is easy to judge that ta should be a BMW brand model. After that, Brother Yao asked someone to inquire, and Ta was actually the new BMW i3. In December 2021, it appeared in the new car declaration list of the Ministry of Industry and Information Technology.
Not long ago, Brother Yan saw the real car at the scene, as a pure electric product, in the current market competition, what characteristics does Ta have, is it very competitive? Use this article to analyze these issues for you.
The outline of the new BMW i3 (hereinafter referred to as the new i3) is very similar to the traditional gasoline version of the 3 Series, you can see at a glance that ta is a BMW brand model, but in many details there is a clear difference from the gasoline version of the 3 Series.
The fully enclosed double kidney grille on the front face is its signature design feature, which retains both brand features and has the function of reducing wind resistance. If you look closely, there is a circle of sky blue embellishments designed inside the grille. And the BMW brand LOGO on the hood is also inlaid with sky blue lines, which is actually a design element of BMW's new energy products.
Inside the slim new "Angel Eye" headlights are a new style of daytime running lights. The front bumper air intake has an intelligent drag reduction function, and when closed, the vehicle wind resistance coefficient can be reduced to 0.24Cd. This value has a strong competitiveness in the same level of models, as a pure electric model, wind resistance energy consumption accounts for a large proportion. The lower wind resistance coefficient not only improves the endurance performance, but also brings a certain degree of handling and stability.
The "shark cheek" deflector is BMW's signature design element, the "shark cheek" on the side of the new i3 body is more slender than other models, and with the air curtain on the front of the front wheel, it can reduce the turbulence generated during driving and reduce the wind resistance coefficient. Moreover, its interior is not completely hollowed out, but resembles a "groove-like" structure that prevents small pebbles rolled up when the front wheels rotate at high speed from scratching the vehicle.
From a design point of view, the "shark cheek" deflector and the lower side of the body line form an overall design, which looks similar to the English letter "L" type, optimizing the wind resistance while showing its movement and elegance. The vehicle side skirt is designed in black, and the contrasting design of the two colors can bring a certain visual impact effect.
The 19-inch aerodynamic wheels with low rolling resistance tires are also designed to achieve lower wind resistance and better energy efficiency.
The tail design is simple and layered, and the blackened 3D stereostemporal LED taillights also add a little dynamic to it, echoing the front face design, and the rear diffuser is embellished with blue lines to highlight the electric identity.
The overall appearance design, Yu Ge feels that Ta retains the BMW brand design gene while integrating new energy design elements, and these designs have strong functionality, which is intended to highlight its identity characteristics.
The interior and space parts of the new i3 are equally outstanding, the interior applies the new design language of the BMW brand, and has a strong sense of technology.
Sitting in the cockpit, the most attractive thing is definitely the 12.3-inch full LCD instrument panel and the 14.9-inch central control LCD screen composed of an integrated floating curved screen, the display has a very high graphic resolution of 200 ppi (pixels per inch), the display effect is very clear. And the entire curved duplex screen is slightly inclined to the driver's side, which is convenient for functional control and information reading.
It is worth mentioning that the new i3 is the first domestic model to adopt the new BMW iDrive 8.0. In fact, the BMW brand is the earliest development of human-computer interaction system of the car manufacturers, it is not like some brands, in order to "technology and technology", the screen size is getting bigger and bigger, but ignoring the convenience and intuitiveness of communication between man and machine - it looks cool, and it is very chicken to use. The BMW iDrive operating system has evolved over 8 generations to this day, and ta's functional and human-computer interaction levels have been widely recognized in the industry.
On the dashboard information display, you can switch between three different themes: sports, energy saving, and comfort. Based on the new principle of information interaction, the central control LCD screen can also be linked, providing optimized interface layout and information display priority.
The central control LCD screen is equipped with BMW's new BMW iDrive operating system 8.0, the car machine has been localized, providing a variety of common app applications, such as WeChat car version, Himalaya, QQ music, etc., as well as the application of rich Tencent small scene 2.0, and support OTA remote upgrade. The response speed of the car-machine system, the fluency of operation and the recognition accuracy of the speech system are all remarkable. The upgraded BMW Intelligent Personal Assistant adopts a new visual image, breathing light balls of different sizes and brightness, so that the intelligent personal assistant has a new emotional expression.
But Brother Yao must say that the important and commonly used physical buttons and knobs have still been retained, and there is no blind "liquid crystal". For example, the iDrive control knob in the central aisle. In fact, when driving, blind exercise can be achieved through the iDrive control knob, which effectively reduces the shift of driving vision.
The gear lever is a paddle design, and the unique B mode of the pure electric model can be used for energy recovery and vehicle deceleration until it stops, maximizing energy recovery efficiency.
In terms of space, the new i3 has a body size of 4872/1846/1481mm and a wheelbase of 2966mm. There's one value I have to emphasize here is the wheelbase, which is a little longer than the wheelbase of the current 3 Series long wheelbase models on sale. So for the 1 meter 94 brother, ta's front/rear space performance is relatively good. If you are normally tall, there will be more margin of space.
The power drive part ta also uses the latest fifth-generation BMW eDrive electric drive technology and excitation synchronous motor, and the new i3 eDrive35L model has a maximum output of 210kW and a peak torque of 400N·m.
The battery pack part adopts a 70kWh high-nickel ternary lithium battery pack, and its battery cell uses NCM811 cathode material, that is, the ratio of nickel, cobalt and manganese is 8:1:1, which reduces the amount of rare metal cobalt and achieves better environmental protection goals. The CRUIC has a cruising range of 526 km under CLTC conditions and supports slow charging and 400V fast charging.
Talking about the fifth generation of eDrive electric drive system, Ta is characterized by a high degree of integration. The three components of the motor, the actuator and the inverter are integrated in an electric drive module. Benefits can reduce mass, reduce volume without taking up rear and luggage compartment space, and reduce energy loss for more efficient power output and conduction.
Excitation synchronous motor uses direct current to make the rotor produce a fixed electromagnetic field, and rotate synchronously with the three-phase rotating magnetic field generated by the stator through alternating current, which has the advantage of high power and fast speed regulation. How to understand? Excitation synchronous motor application is an artificial magnetic field, the addition of excitation coil, adjust the magnetic field can change the speed, the vehicle in the low speed and medium speed, the efficiency will not be very different. According to the official 0-100km/h acceleration results, the acceleration time of the new i3 is only 6.2s, which is similar to the gasoline version of the 3 series 330i model.
In fact, although the new i3 is a pure electric model, it does not have any compromises in terms of sportiness and comfort.
Ta's front cabin is equipped with a shock absorbing top tie rod, the front and rear chassis parts of the application of anti-roll bars to enhance the rigidity of the vehicle, the front and rear suspensions are equipped with hydraulic shock absorption technology, and the rear axle is equipped with adaptive air suspension for the first time, taking into account both comfort and driving stability.
In addition, according to the official information, ta's center of gravity is 44 mm lower than the 3 series, the front and rear wheelbase is wider, and equipped with DSC dynamic stability system including ARB anti-slip stability control unit, which shows that Ta still emphasizes the handling and driving pleasure that the BMW brand has always insisted on.
So after the opportunity, brother must experience the dynamic properties of Ta, personally feel that using Ta to drift should not be a big problem.
In terms of charging, bmw instant charging has dynamically linked 380,000 public charging piles, of which 200,000 are DC fast charging piles, and about 50,000 charging piles in the country can provide plug-and-play services. And there are more than 390 BMW dealers that can provide charging services. The extensive network layout and fast charging will bring a better user experience to domestic consumers.
Seeing the new i3, Brother Yan is thinking about a question, when the traditional luxury brand touches the "electricity" new energy market, will it usher in a reshuffle? Traditional brands like BMW began to exert their strength, and compared with the new forces of car companies, they have more accumulation and experience in manufacturing, process, vehicle verification, supplier quality control and so on.
In fact, building a car is not a simple thing, it requires a long period of accumulation and strict process control. Good products need to have better reliability, which traditional car companies have more advantages.
From the perspective of the market, new energy vehicles are constantly accelerating the substitution effect on the fuel vehicle market, especially around the battery and other "three electricity" technology, intelligent network technology and other key areas of the continuous development of the boost, compared with other markets, China's new energy market is not only the scale of the dominant volume, the diversity of model categories, product difference span.
On the one hand, new energy meets the current environmental protection requirements, and on the other hand, it has great advantages over fuel vehicles in terms of vehicle cost. There are also more and more consumers around Brother Yao who are studying and even have purchased new energy products. Traditional car companies also have their own unique demands or pursuits for products. For example, like the BMW brand, the joy of driving has always been the goal of Ta. I have also test-driven some BMW brand new energy products before, such as SAV models like the iX3, which are not very different from the traditional gasoline version of the driving experience, and even the experience of throttle response and power output is faster and more direct than that of the fuel version. From design to configuration, the new i3 also highlights the sporty and technological characteristics of Ta. The accumulation of traditional car companies over the years, and their understanding of their own products, are also an important part of the lack of many new car companies. In the platoon deployment of electrified products, bmw brand for electrification, taking into account the characteristics of different stages of development of the industry, BMW has been in accordance with its own rhythm, steady and steady, ladder to promote the cause. BMW's long-term sustainable, systematic and advanced long-term development plan is still explosive and has a good future.
