New benchmark for electric family driving control BMW i3 test drive experience

With the advent of the electric age, we have to accept the reality that the internal combustion engine is gradually moving away. For many "fuel parties", cars without an engine seem to have lost their souls and become somewhat "uninteresting".

For a long time, I felt like I was one of those people who had "gas in their blood" and would unconsciously equate the pleasure of driving with the internal combustion engine, as if there were only the roar of the engine and the rush of shifting gears. "Energy" is the source of happiness.

So at the beginning I didn't take this pure electric BMW "in the eye" - after all, "what driving pleasure can an electric car have?"

Does dopamine come with the current?

The slap in the face is always very accurate and timely. After test driving the new BMW i3, I was a little surprised and even confused. Does dopamine really come with the current?

Maybe without the roar of the engine, it will make you feel a little strange, but when you step on the accelerator pedal, you will find that "it's still the familiar smell".The i3 zero-hundred acceleration can run to 6.2 seconds, and the acceleration is very direct without any sluggishness.If you are a friend who advocates driving fun, then you will definitely love this i3.Although it is a pure electric model, the layout of the rear-mounted rear-wheel drive and the close to 50:50 front-to-rear weight ratio allow you to still enjoy the outstanding driving performance that BMW has always been proud of. The three words "oil to electricity" can be easily solved.

It is worth mentioning that the i3 adopts the same BMW electric drive system as the iX3. The electric drive unit integrates the motor, inverter and transmission. The maximum power of the excitation synchronous motor is 210KW and the peak torque is 400N m. The "golden combination" of the times guarantees surging power output at full speed.Compared with the permanent magnet synchronous motor mounted on other brands of models, the excitation synchronous motor cancels the permanent magnet, and provides a magnetic field through the excitation coil, which can better ensure the burst of high torque at full speed, and the speed regulation is more accurate.At the same time, the excitation synchronous motor also reduces the dependence on rare earth resources, which is more in line with the current concept of sustainable development.

In addition to the excellent performance in acceleration, the BMW i3 also handles cornering and shock filtering quite well. With the DSC dynamic stability system including the ARB anti-skid stability control unit, it provides the vehicle with better traction and grip, and has more excellent cornering. Attitude and performance.In order to offset the adverse effects of the large-capacity battery pack due to inertia when the vehicle is turning, the i3 is also equipped with front and rear anti-roll bars, and the cabin is equipped with a front shock absorber top pull rod. Faster and more timely.In addition, the front and rear suspensions of the new BMW i3 adopt innovative HRS hydraulic rebound damping technology, and the rear axle is equipped with adaptive air suspension for the first time, which can make the driving on bumpy road conditions more stable and comfortable.

It's not as simple as changing a motor

Because the i3 and the fuel version 3 series were both born on the BMW CLAR fuel-electric symbiosis platform, many people will subconsciously think that the i3 is nothing more than replacing the engine with an electric motor, and for many "oil-to-electric" car companies, there is indeed a rough The ground ignores the interior space, safety and driving experience, and only does the mechanical replacement of the engine and the battery motor. This is one of the reasons why everyone expresses their incompetence when it comes to "oil-to-electricity".

However, the BMW i3 is very different from this type of "oil-to-electricity". The new car not only allows the i3 to perfectly follow the sports driving fun of the fuel 3 series through innovative electric drive technology and classic chassis tuning, but also pays special attention to safety issues.Thanks to BMW's accumulation of all-round technologies in the field of power batteries, including cell raw materials, chemical formulations, internal structure design of battery packs, and lean production processes, the power batteries carried by the i3 have excellent performance, energy density, cruising range, safety and The quality and reliability of the whole life cycle and other dimensions can achieve a perfect balance.

Safety outside of driving control

From the on-site MR mixed reality experience, we learned that the high-strength aluminum alloy material on the outside of the i3 battery pack, as well as the multiple reinforcing beams inside, the side buffer structure, and the design of the module's energy absorption can all protect the battery through a physical defense mechanism. Safety.The maximum redundancy design on the inner side and bottom also reserves enough buffer space to avoid damage to the battery module as much as possible even in extreme cases.

Details such as waterproof rubber sealing ring and composite fireproof upper cover make the i3 battery pack have the highest level of IP67 dustproof, waterproof and fire blocking effect. At the same time, there are 4 explosion-proof pressure relief valves and explosive discharge devices. It can ensure that the power is cut off within 3 milliseconds, and the pressure balance inside and outside the battery pack can be quickly adjusted to prevent the battery from catching fire and eliminate potential safety hazards.

One of the biggest worries of people about trams is battery life. The industry-leading adaptive energy recovery of the new BMW i3 not only makes the driving experience smoother, but also brings more peace of mind to driving.The i3 can automatically adjust the energy recovery strength according to the current road conditions. This feeling is really wonderful, as if it understands the driver's mind, which is completely different from the traditional drag feeling. In addition, the recovery strength can also be displayed on the touch screen View the visual icon of the , and keep the real vehicle condition synchronized at all times.

The new BMW i3 is equipped with a CATL 811 nickel-cobalt-manganese ternary lithium battery with a total capacity of 70 kWh, with a maximum cruising range of 526km under CLTC standard conditions.Although there is no complete endurance performance test for the i3 this time, we can see from our previous actual test of the ix3 that BMW's battery life has always been relatively solid, and there is basically no chance of leaving you halfway due to false mileage marks. Happening.The displayed mileage is the actual mileage, and even due to differences in driving habits, under the precise calculation logic, the remaining driving mileage will not decrease but increase after switching from intense driving to soft mode.

Whether it is driving control, travel safety, or long-term battery life, if you want to deal with all this well, it is not something that can be solved by just changing the motor.The seemingly simple logic requires a series of rigorous and solid design logic and technical craftsmanship behind it. It can be said that the i3 has excellently continued the driving pleasure and control level of the fuel version of the 3 series. There are doubts about the new car, and the i3 undoubtedly handed in a reassuring high score.

Classic upgrade both inside and outside

While achieving the ultimate in internal strength, the all-new BMW i3 has also made bold innovations on the basis of BMW's consistent classic design. With a more pioneering and avant-garde design language and a new interior configuration, it presents a more cutting-edge dynamic pure. The beauty of electricity.

In terms of appearance, the i3 adopts more targeted detail changes to highlight itsnew energyidentity, and also has aerodynamic functions, such as a closed grille, rear diffuser, a new style of 19-inch aerodynamic wheels and Unique designs such as low rolling resistance tires, intelligent drag reduction grilles, and shark gill diversion grooves can effectively reduce wind resistance and energy consumption, making the vehicle wind resistance coefficient as low as 0.24Cd.

At the level of digital technology, i3 has humanized configurations such as digital keys and comfortable entry, making the boarding experience more convenient and intimate.At the same time, the integrated floating curved screen is also the first time that it has been applied to a domestic model. The screen integrates a 14.9-inch touch screen and a 12.3-inch digital instrument panel, and is slightly inclined towards the driver, making the operation more convenient, smooth and natural.The gear lever has become more compact and futuristic.The air-conditioning control area is integrated into the car screen, minimizing physical physical buttons and making it more technological.The in-vehicle system is supported by ID8, which not only upgrades the visual image of IPA, but also carries rich digital products such as the localized innovative application WeChat in-vehicle version and Tencent Small Scene 2.0.

In terms of driving space, the slender body of nearly 5 meters and the ultra-long wheelbase of 2966 mm make the interior space of the i3 very spacious.Although it is flexibly produced on the same platform as the fuel version of the 3 series, thanks to the fact that BMW has taken into account the needs of electric vehicles since the beginning of development, the i3 does not have a situation where the platform of other brands of electric vehicles is too high, which affects the ride comfort. On the contrary, the i3 The rear seat has a larger seating space, and the riding posture can be more flexible and stretched. The intuitive feeling is that the head can be raised, the legs can be put down, and the sitting posture is more ergonomic. At the same time, the trunk is not affected by the battery, and the volume is still very considerable.

write at the end

The i3 is not as simple as the battery will be stuffed into the 3 Series.The so-called evolution of electric with 3 series, i3 is based on the complete continuation of the sports attributes of the fuel version of the 3 series, and also gives more innovative attributes and technological content in the details. On the right, it has achieved a good balance in terms of comfort, space practicality, battery safety, driving assistance capabilities, and battery life. It is really difficult to bypass a 3-series in life.
