These two days, I believe many friends are paying attention to a medium-sized car, Xiaopeng P7. Indeed, it has a 3-meter wheelbase, a maximum range of 706km, a cool appearance and a self-developed xpilot auxiliary system, and has released a pre-sale price of 240000-370000, which is eye-catching. Because Xiaopeng P7 has many highlights in terms of endurance, size and pricing, people pay little attention to its performance. In fact, the performance and power of this car can't be underestimated. We have done an analysis of its paper strength with competing products before (here's a review). This time, Xiaopeng officially came to a real-life test: at the end of February, Xiaopeng P7 four-wheel drive high-performance version of the project was loaded in Huizhou Fukuoka track, with the model s 100D dual motor four-wheel drive version, Panamera 3.0T rear drive and m43.0t rear drive were tested for a performance comparison, covering 0-100 acceleration, 100-0 braking, 15m pile winding, elk test, circuit lap speed and NVH test. The basic parameters of the four vehicles are as follows: in the end, except for the 0-100km / h acceleration project, P7 ranked second, and all other projects ranked first, with good performance. P7, as an electric vehicle, has a front motor with a peak power of 120kw and a peak torque of 265n · m, and a rear motor with a peak power of 196kw and 390n · m. It is relatively easy to achieve excellent 100km acceleration results, but several other parameters are not available, such as brake distance. In terms of braking, Brembo opposed four piston sports calipers are used in Xiaopeng P7. Compared with ordinary single piston calipers, they have stronger rigidity, more balanced braking force, shorter reaction time and shorter braking distance. Compared with the common brake system, Brembo has the advantages of short braking distance, good braking effect and small unidirectional wear, which improves the service life of brake pads. In addition, Xiaopeng has also jointly developed an intelligent active continuous damping system with ZF and other teams, through two front axle acceleration sensors, two rear axle height sensors and six axle IMU (internal measurement) located in the controller Unit inertial measuring instrument) sensor signal, automatically adjust the damper damping into comfort, motion and standard modes, and adjust the damper damping according to the road conditions and vehicle driving conditions. Based on the steering wheel angle and IMU information of the whole vehicle, the system can adjust the damping of the shock absorber on the inside and outside of the vehicle, reduce the vehicle body attitude deviation, and make the vehicle body attitude more stable. When braking or accelerating, the system can adjust the damper damping of front and rear axle respectively based on the accelerator, brake pedal signal and IMU information of the whole vehicle, reduce the nodding phenomenon of the vehicle, so that the vehicle can brake and start more smoothly. If there is a pit in front of the vehicle and the front wheel falls into the pit, the acceleration sensor of the front axle will monitor an excessive acceleration of the front axle, so as to increase the current output, reduce the damping of the shock absorber, make the vehicle pass through the pit more comfortably and smoothly, and bring more comfortable experience to the passengers in the vehicle. In this way, Xiaopeng P7 not only has guaranteed endurance, but also does not lose control. And its pre-sale price is 240000-370000. In this price range, it's difficult to buy a car with a 3-m wheelbase; it's not easy to take into account the highlights of luxury, endurance, control, etc., so Xiaopeng P7 is indeed a sincere product. As the flagship of the family, the luxury level of Xiaopeng P7 does not fall behind. It has a series of configurations that increase the sense of luxury and ceremony, such as Dana sound with a raised and lowered tweeter, nappa leather seat (optional), and the function of "easy access" to the seat. Of course, in terms of intelligence, Xiaopeng P7 is not falling behind. It has a 10.25-inch LCD Meter and a 14.96-inch central control screen, and its processor has been replaced by a car gauge level Qualcomm snapdragon 820a chip, and it is equipped with 8g memory, which improves the computing power and processing speed from the hardware level. At the same time, in terms of automatic driving assistance, Xiaopeng is one of the few manufacturers that adopts self-developed mode. Its autopilot system, xpliot, is currently iterated to version 3.0, which can realize the mainstream L2 level autopilot functions on the market and Ota. Here we summarize the highlights of Xiaopeng P7: 1. The comprehensive endurance mileage reaches 706km, which is worthy of the top; in addition, there are models with the comprehensive endurance mileage of 552km / 568km / 656km. 2. The pre-sale price is 240000-370000. 3. Excellent handling, performance and driving quality. 4. It is positioned as a pure electric medium-sized vehicle, but the actual wheelbase is close to 3m, reaching the level. 5. Xpilot 3.0, a self-developed automatic driving aid system. ■ according to the official news, P7 will be listed on April 27, and delivery will be achieved from May to June 2020. Compared with competitive products (hanev, et, dc1e, etc.), it has the advantage of "preemptive". Since this year, model 3, which has experienced a long battle, has launched a standard range of 445km (299050000 yuan) and a long range of 668km (33905000 yuan). The price frame coincides with the pre-sale price of Xiaopeng P7. Can Xiaopeng P7 compete in the future market competition? We'll see!
