BMW i3 EV Sedan

Under the wave of electrification, the development of the new energy vehicle market has entered a new stage. Car companies such as NIO and LIXIANG already have the hard power to compete with luxury car manufacturers. For BMW, Mercedes-Benz, and Audi, how to quickly gain a foothold in the market is more critical. BMW has invested heavily in the new energy vehicle market, among which the BMW i3 has achieved good results since it entered the market. Compared with major competing models such as NIO ET5 and Tesla Model 3, BMW i3 naturally has certain advantages and is a phenomenal product in the market.

Among the three automakers BMW, Mercedes-Benz, and Audi, BMW actually launched a pure electric model 10 years ago, and launched a hybrid model BMW i8 in 2014. This model has certain advantages in terms of appearance and carbon fiber frame. But at that time, the recognition of pure electric models among automakers was not high, and the supporting resources such as charging piles were not perfect, so they failed to achieve good results in the market, but it also shows that BMW's new energy technology reserves are sufficient. . Therefore, it seems natural that the BMW i3 will become popular as soon as it enters the market.

In terms of product strength, the performance of the BMW i3 is good enough. The new car is equipped with the fifth-generation BMW eDrive electric drive technology and rear-excitation synchronous motor as standard. The entry-level model has a maximum output power of 210KW and a peak torque of 400N.m, and it only takes 6.2 seconds to accelerate from 100 kilometers to 100 kilometers. The mid-to-high-end model has a maximum output power of 250KW and a peak torque of 430N.m. It only takes 5.6 seconds to accelerate from 100 kilometers, and the power output is strong enough. It is better than the power performance of the models of the new car-making forces. The motor of Zeekr 001 has a maximum output power of 200KW, a peak torque of 343N.m, and an acceleration of 100 kilometers in 6.9 seconds. The maximum output power of the motor of the Xpeng P7i is 203KW, a peak torque of 440N.m, and an acceleration of 100 kilometers in 6.4 seconds. In addition, the excitation synchronous motor used by BMW does not contain rare earth materials. The power generation characteristic is the best solution for a single motor, which can ensure that the car can burst out peak torque at low speeds and high speeds, and can feel a strong sense of pushing back when accelerating under battery life. Although excitation motors cost more than permanent magnets, BMW vehicles have not replaced them.

The fuel version of the BMW 3 Series is called the driver's car, and the BMW i3 performs equally well in terms of driving control. The car is built based on the BMW CLAR architecture. It adopts a double-ball joint spring shock-absorbing strut front axle, and is equipped with an adaptive air spring rear suspension as standard, and cooperates with front and rear hydraulic rebound shock absorption technology to ensure comfort performance. . At the same time, the rear chassis parts and the engine compartment of the BMW i3 have been strengthened, equipped with a rear anti-roll bar, matched with the front shock absorber top tie rod and the rear chassis reinforcement kit. The rigidity of the body is improved to ensure the stability of the car body in curves and complex road conditions, and the overall driving experience is relatively advanced.

In terms of battery life, the BMW i3 is equipped with a ternary lithium battery with a battery capacity of 70kW h and 79kW h, and a pure electric mileage of 526KM and 592KM respectively. In addition, the BMW i3 is also equipped with an adaptive energy recovery system, which can automatically adjust the intensity of energy recovery according to the current road conditions. With two heat pump systems, the performance of the BMW i3's endurance performance and endurance achievement rate are relatively good. A number of media have conducted actual battery life measurements in winter, among which the battery life of the BMW i3 and BMW iX3 is satisfactory enough. The power consumption per 100 kilometers of BMW i3 is only 14.1kw/h, and it supports fast charging, which can recharge 97km in 10 minutes. Moreover, it only takes 41 minutes to charge from 5% to 80%. Long battery life + fast charging can already alleviate the user's mileage anxiety to the greatest extent.

In terms of intelligence, the performance of the BMW i3 is also quite brilliant. The interior of the car uses a dual-connected large screen consisting of a 12.3-inch LCD instrument panel + a 14.9-inch LCD central control screen. It enhances the sense of technology. The central control panel is equipped with iDrive8 intelligent car-machine system. This car-machine system has rich functions, and most of the functions can be realized in the second-level menu. This kind of interactive experience is the optimal solution for human-computer interaction. At the same time, it also supports functions such as line Carplay, AutoNavi map navigation, 50-meter tracking and reversing, active cruise, etc., and the intelligent driving assistance of BMW i3 has reached the L2 level, supporting functions such as lane departure warning and lane keeping assistance. Cooperating with the automatic parking system, its intelligent performance is similar to that of new car manufacturers.

The importance of space performance in the car market is self-evident. The wheelbase of the BMW i3 has reached 2966mm. All users in the car have enough head and leg room. The seats are wrapped in Sensatec 2.0 synthetic leather. And the thickness of the seat cushion and backrest has also been thickened, so there is no problem with the riding comfort. In terms of ritual, the BMW i3 is equipped with an angel wing welcome light carpet, intelligent sensor ambient lights in 6 colors and 11 tones, and a panoramic sunroof. In terms of comfort configuration, the seats support memory, heating and other functions. In addition, the car is also equipped with a high-efficiency dust filter with PM2.5 filtering function to ensure the air quality in the car, and the overall riding experience is more comfortable.

The exterior design of the BMW i3 is stylish and sporty, the air intake grille is closed, and the surrounding is decorated with chrome-plated trim to enhance the texture. After the headlights of the angel eyes are lit, the visual effect is good, and the air intake design is more three-dimensional. Thanks to the design of the long axle and short overhang, the whole body looks stretched and smooth, the shape of the wheels is decent, the style of the rear is relatively tall, and the lines on the trunk lid are more prominent. The 3D three-dimensional suspended taillights have a good visual effect after being lit, and the rear surround is decorated with an exaggerated diffuser, emphasizing the performance range.

Judging from all aspects of performance, the BMW i3 has indeed reached the mainstream level, and it is also a rare model in the market that insists on individuality. It does not blindly insist on emphasizing intelligent performance, but focuses on consumers' car experience and driving experience. Moreover, it has strong power output and stable battery life. It continues the advantages of the fuel version of the BMW 3 Series. It is indeed an all-round luxury mid-size car. Compared with NIO ET5 and Tesla Model 3, it is more pragmatic.
