Fan Fei F7 is going to play with Conford.

When electric vehicles have no air intake grille and pursue lower wind resistance, the appearance of many electric vehicles on the market always makes us deja vu, and the appearance is increasingly lacking in personality and brand recognition.

Therefore, many manufacturers focus on the interior of vehicles, such as some emphasize chassis movement, some have excellent intelligent driving level, and some have functional experience for home users. Everyone will make the characteristics and differences of their own models for the market segments and build a moat for the products.

For Fan Fei, a high-end pure electric brand owned by SAIC, how to make consumers remember and build their own product moat within 30W is also a matter that needs careful polishing.

Since the end of 20021,Fan Fei Automobile has been officially named, and has successively released a brand-new SUV R7 and a medium and large-sized car F7 with a pricing and pre-sale range of 280,000-390,000, which has entered one of the main battlefields of high-end new energy vehicles in China.

For such a battlefield, it is not an exaggeration to describe it as a wolf in front and a tiger behind. Judging from the current market performance of Fan Fei R7, as a new brand, Fan Fei's voice volume is weak, and it is urgent to find new communication ideas suitable for its own product characteristics and build a moat. Therefore, this work will be more urgent for the medium and large-sized car F7, which has already started pre-sale and will be listed on March 27th.

Fortunately, after the test drive of YCar Review F7, this kind of worry has been alleviated a lot, because we see that Fan Fei has a clear answer to the understanding of a medium and large pure electric vehicle and a clear judgment on his own positioning, that is, comfort.

Comfort is not a new word for large and medium-sized pure electric vehicles. Before this, both Krypton 00 1 and Weilai ET7 mentioned the topic of comfort. The difference is that Fan Fei F7 is completely comfortable, and there is not much luxury in both sports and comfort. Getting such an answer involves many factors, such as product design, product positioning, user portrait, manufacturing cost and so on. And find your place in the trade-off.

Judging from the experience after the F7 test drive, the score of this answer in my mind is also considered as an excellent student.

? Are you comfortable?

The daily use of a medium-sized and large car is bound to be accompanied by family trips or long-distance trips, so driving comfort is bound to be an important factor to measure whether it is competent or not.

Fan Fei F7 Company has made great efforts to create the comfort of the cockpit, and they specially chose an interesting name called "Bach Cockpit", named after the world famous composer Bach.

Since it is called Bach, there will naturally be a part related to music (sound). Fan Fei F7 has 3D vector sound effects, which will keep the direction of sound consistent with the direction of attention in intelligent driving, navigation, system prompts and other scenes.

For example, when intelligent driving is turned on, the intelligent driving voice is directional or directional, and you can also judge the direction according to the sound. In navigation, you can know whether to turn left or right according to the direction of the sound, so as to avoid driving mistakes caused by vague prompts. When reversing, you can feel the distance from the rear obstacle through the sound, that is, the distance from the sound. When you share iQiyi with the co-pilot's family with the three-finger flying screen, the sound will let you know that there is an application on your right; If the co-pilot friend sets a new address for you, the new route will also come from your right.

To realize the sense of orientation of the sound in the car, you must have a good hardware foundation. In addition to the 5. 1 (low-end) /7. 1 (middle-end) sound system on Fan Fei F7, F7 is also equipped with ADI DSP audio processing chip, which forms a dual DSP solution with Hexagon DSP module of 8 155 chip in the car. This independent DSP chip has the characteristics of fast start-up, low delay and high efficiency, and also provides a good audio performance foundation for the sound requirements of many special scenes.

In addition, Fan Fei has also made a "sound workshop", where you can customize your ringtone, change different sound effects of car search, and integrate the sound you want into different scene modes, which can be greetings on the bus, adding a sound to the wallpaper, and making a holiday egg yourself. At the same time, Fan Fei will also connect with the creator's platform to preset various high-quality sounds. These high-quality sounds will be launched in stages, which can be OTA.

Fan Fei F7 put the hearing comfort in a very important position and created a more interesting experience. It is indeed more avant-garde and trendy than other models.

Another core of comfort must be related to the seat. Therefore, Fan Fei F7 deeply studied the problem of human waist compression, and optimized the waist comfort of Bach chair.

Through mechanical analysis, Fan Fei's seat engineering team believes that "waist-friendly" seats can not only solve the problem of waist, but also involve the supporting force of feet and calves, the included angle between seat back and cushion, the supporting force, pressure and contact area between cushion and backrest.

Therefore, the adjustment of four-way lumbar support and a total of 70mm soft foam layer mean that it can fit the back curve as much as possible. 580mm long cushion, electric leg rest and 65 mm * * * long three-layer soft foam layer, which brings a larger cushion contact area. All in all, these ergonomic designs make the F7 seat more comfortable than similar products. This can also be clearly felt during the test drive, especially in the front seats, the sense of wrapping and hardness is just right, and it is not tired after driving for a long time.

There is also a rather elegant optimization. Fan Fei F7 studies the frequency of vibration and human intolerance (which can be simply understood as discomfort) under dynamic working conditions, so as to optimize the overall spectrum of seats and chassis. Simply put, by strengthening the structure of the six positions of the seat, the vibration frequency of the seat can avoid the main intolerable frequency range of the human body, so as to achieve a more stable and comfortable riding experience.

In order to prove the effectiveness of these optimizations, Fan Fei specially took this seat and obtained the "Comfort Star" certification from China Automotive Research Institute, and Fan Fei F7 became the first vehicle to get full marks in 30 sub-items of pressure distribution.

Fan Fei F7 has four comfortable seats in the front and rear rows, all of which are equipped with heating and ventilation. The main driver has added the functions of electric leg rest and "hot stone physiotherapy" based on partition control. Let the front and rear passengers enjoy uniform comfort, and everyone deserves attention.

? Is it comfortable to drive?

Fan Fei F7 is equipped with a rear axle motor with a maximum power of 250kW and a peak torque of 450 N m. On this basis, 150kW and 250N·m front axle motors are added to the four-wheel drive model. The rear-wheel drive model accelerates by 5.7s, and the four-wheel drive model accelerates by 3.7s. ..

For a comfortable car, such power is a bit excessive. You can find endless driving pleasure in Fan Fei F7' s driving mode. Performance can be set to comfort, standard and sportiness, or it can be set to "adaptive" mode, that is, the vehicle will automatically adjust its dynamic response state according to your driving habits. It is really good news for users who are difficult to choose, and the actual dynamic response can meet the needs of most people. After all, the absolute dynamic data is there. During most of the test drive, I adapted myself. As long as I am willing to step on it, strength will never let me down.

Fan Fei F7 comes standard with the Onebox electric brake system, and the braking response time is only 150ms, so the foot feels the same. The pedal stroke is also very linear, and the depth of the pedal is well matched with the braking force, and basically no adaptation time is needed.

The high-equipped models are equipped with Brembo four-piston calipers, and the low-equipped models are ordinary four-pistons. I simply tested these two models. There is no obvious difference in the sense of feet between the two in daily walking. Only when braking at high speed, the obviously shortened braking distance can realize the good of Brembo. In short, ordinary braking is enough, and Brembo will make you more confident.

F7 also gives three options: simple, standard and calm. Easy will be more friendly to female users. I recommend the standard for men. The steering feel in stable mode is a bit sticky and not recommended. The steering belt of Fan Fei F7 increases with the speed, which means that after you drive at high speed, the steering wheel will sink, reducing the possibility of human misoperation.

NVH quiet performance is an important indicator of comfort, and Fan Fei F7 can give a high score as a whole. First of all, thanks to the ultra-low drag coefficient of 0.206Cd, the starting point of wind noise suppression is even better. Secondly, engineers have done a lot of optimization in the key areas of front engine room cover parting, wiper, front windshield, front triangular window, front door sealing system, rear side window, rear fixed triangular window and hatchback tailgate 10 wind noise, thus reducing the wind noise of F7 as a whole.

In the aspect of road noise suppression, Fan Fei F7 adopts ultra-high rigidity wheel hub, and the wheel hub stiffness reaches 73E, which is 20% higher than the mainstream wheel hub, effectively reducing the road noise index.

Fan Fei F7 also carried out a series of targeted optimization on the motor components. Through the structural optimization of the integrated motor, the operation of the motor reached an ultra-quiet state. I also clearly felt this during the test drive, and the motor howling of F7 was really small.

The comfort of the chassis, F7 unexpectedly excellent, which is the most amazing place in the test drive. You might guess whether to use air suspension or CDC electromagnetic shock absorber, but it's not.

F7 is a double wishbone multi-link suspension with traditional mechanical structure. The technologies and activities we can talk about are mainly Weibak hydraulic bushing and Tenneco high-end MTV CL series recovery spring shock absorber, plus Michelin PS EV tires, all of which have obvious longitudinal impact vibration isolation effect.

The test drive was specially arranged to enter SAIC-GM's automobile test site in Guangde. We drove F7 through the central Belgian highway (a typical rugged road made of granite). This road comes from the Belgian slate road and is named as a typical rotten road. The lateral swing of the car body is not big, the suspension rebounds quickly, the violent bumps are cleaned, the chassis is not loose, and the integrity is high.

While driving on the open road, the advantage of this good foundation is more obvious. At the same time, it retains a slight sense of road and the softness is just right. It doesn't float like krypton 00 1, but it is more elastic. Another advantage of this toughness is that passengers are less likely to get carsick.

This conclusion proves once again, don't be obsessed with hardware, the adjustment level is the most important.

? Test drive summary?

Fan Fei F7 tends to feel comfortable in static and dynamic directions, and it is wise to learn from other modes. At the same time, it is also limited by hardware conditions (mechanical chassis), and both of them obviously do not conform to the physical laws.

Under the existing conditions, the hardware is adjusted to the best state, which shows the comfortable effect of not losing suspension and electromagnetic levitation, which not only adds extra points to the product strength, but also saves some manufacturing costs, which is more conducive to the final pricing strategy.

In addition, in intelligent driving and automobile system, Fan Fei F7 adopts 8 155 chip to synchronize with Wei Ying.
