Among the many new car-making forces, car companies such as Weilai, Xiaopeng and Ideal have gradually become the main force in the sales of new energy vehicles, in addition to the traditional car companies, BYD has begun to use pure electric or plug-in hybrid systems with years of research on new technologies such as batteries. In the joint venture brand, Volkswagen launched a pure electric vehicle model such as ID.3, mainly to enter the pure electric vehicle market of less than 200,000. The following takes the 2021 ID.3 Pure Pure Edition as an example to analyze the car.
The ID.3 uses a shape similar to the Golf hatchback, based on the MEB platform, the chassis arrangement uses a single motor rear-drive, the motor and differential assembly are installed in the rear axle space under the rear seats, although the length is only 4261mm, but the wheelbase reaches 2760mm, so it is also divided into the ranks of compact cars. In the design of the whole vehicle, the decoration of the C-pillar appliqué pattern, the sloping tail, and the slender front of the car are more sporty and personalized.
The pure version of the wheel uses the 215/55 R18 size, which looks more reasonable, because the medium and high-end models use the 215/45 R20 size, and the width of the wheels of the two models is unchanged, the height is similar (one is 693.7mm, the other is 701.5mm), but the 20-size wheels are used, just to create an exaggerated sense of sport. The rear wheel uses drum brakes, which will not hinder the vehicle when driving, and the maintenance cost will be reduced in the later stage. But there is a problem that the rear axle is used as a drive axle, and the weight is also concentrated on the rear axle, which is a test of the stability and braking force of the rear axle brakes.
For the rear wheel use of drum brake is a controversial topic, MEB platform use of drum brake on the one hand is a cost control problem, the other is drum brake also has many advantages. Pure electric vehicles can recover kinetic energy through the motor when braking or decelerating, and the heat generated is also less, which can reduce the number of brakes; the drum brake reacts faster, and can also provide greater braking power, and the deceleration effect produced by kinetic energy recovery is more stable. In the actual driving process, the braking force distribution of the ABS pump is balanced and stable, and there will be no problems such as brake deviation.
In terms of power, the car's motor output is 170Ps maximum horsepower, and the driving mode provides a sporty, personalized, economical and comfortable option, which is completely enough for home and more suitable for traveling in the city. In economy mode, the accelerator pedal acceleration is very linear, the power output is like a combination of a naturally aspirated engine + CVT, the acceleration is smooth, and after the speed exceeds 110km/h, it will feel that the power is not enough. In sport mode, the power output is more abundant, the throttle response is more sensitive, and the power output in the rear section is also insufficient.
The rear drive arrangement can be compactly arranged in the rear axle of the three-in-one electric drive system, the front axle can have more space utilization, the steering radius of the front steering wheel is small, the electronic power steering system does not change significantly with the speed, and the road sense feedback is not obvious. The front axle's main pin has a large forward inclination angle, which can provide a full return torque and a very fast return speed. The front McPherson and rear multi-link independent suspension have excellent texture, and have the texture of the chassis that Volkswagen has always been "stable and thick", and the size of the road can be quickly absorbed. At medium to high speeds, the noise coming to the car is also limited and quite quiet.
In summary, volkswagen ID.3 is a boutique car with good production process and excellent driving texture, what do you think?
