When electric vehicles do not have air intake grilles and pursue lower wind resistance, many electric vehicles on the market always look familiar to us, and their appearance increasingly lacks personality and brand recognition.
Therefore, many manufacturers are focusing their efforts on the interior of the vehicle. For example, some emphasize chassis movement, some have excellent intelligent driving levels, and some have functional experience for home users. Everyone will make the features and differences of their own models for market segments and build a product moat.
For Feifan, a mid-to-high-end pure electric brand owned by SAIC, how to impress consumers in the 30W range and establish its own product moat is also a matter that requires careful polishing. .
Since the end of 2021, after Feifan Automobile was officially named, it has successively released the new SUV R7 and the medium and large sedan F7 under the new brand. The pricing and pre-sale range has been selected between 280,000 and 390,000, entering the domestic market. One of the main battlefields for high-end new energy vehicles.
For such a battlefield, it is not an exaggeration to say that there are wolves in front and tigers in the back. Judging from the current market performance of Feifan R7, Feifan, as a new brand, has a weak voice and urgently needs to find a new communication idea that suits its product characteristics and build a moat. So for the mid-to-large sedan F7, which has already started pre-sale and will be launched on March 27, this work will become more urgent.
However, fortunately after the Y Car Review test drive F7, this worry has been alleviated a lot, because we have seen that Feifan has a clear answer and positioning for a medium to large pure electric car. Clear judgment, that is comfort.
Comfort is not a new word for medium and large pure electric cars. Previously, Jikrypton 001 and NIO ET7 both mentioned the topic of comfort. The difference is that Feifan F7 is completely comfortable and does not have too much extravagance to balance sports and comfort. Obtaining such an answer involves many factors such as product design, product positioning, user portraits, and manufacturing costs, and you must find your own position among the choices.
Judging from the experience after the F7 test drive, this answer can be regarded as an excellent student in my mind.
? Comfortable to sit on?
The daily use of a medium-to-large car is definitely to take the family with you or travel far away, so the driving comfort must be a measure of whether it is competent. important factors.
Feifan F7 is very attentive to the comfort of the cockpit. They also specially gave it a very interesting name called "Bach Cockpit", named after the world-famous composer Bach.
Since it is called Bach, there will naturally be parts related to music (sound). Feifan F7 is equipped with 3D vector sound effects, which will keep the direction of the sound consistent with the direction of attention in the scenarios of smart driving, navigation and system prompts.
For example, when smart driving is turned on, the smart driving voice is directional or directional, and you can also judge the direction based on the sound. In navigation, you can follow the direction of the sound to know whether to turn left or right, thus avoiding driving errors caused by blurred prompt sounds. When reversing, you can feel through the sound the distance to the obstacle behind you. That is the distance of the sound from you. When you use three fingers to fly the screen and share iQiyi with your family in the passenger seat, the sound will let you know that an application has gone to your right; if your friend in the passenger seat helps you set a new address, the new route will also It's coming from your right.
To achieve a sense of direction in the sound in the car, you must have an excellent hardware foundation. In addition to the Feifan F7 supporting up to 14-channel 5.1 (low configuration) / 7.1 (mid-to-high configuration) sound system, the F7 is also equipped with an ADI DSP audio processing chip, which is connected to the Hexagon DSP module of the 8155 chip in the car. Constitutes a dual DSP solution. This independent DSP chip has the characteristics of fast startup, low delay, and high efficiency, which also provides a good audio performance foundation for the sound needs of many special scenes.
In addition, Feifan has also created a "sound workshop". In this function, you can customize your phone ringtone, replace different car-finding sound effects, and integrate the sounds you want into different In the scene mode, it can be a greeting when you get in the car, you can add a sound to the wallpaper, or you can make a festive Easter egg yourself. At the same time, Feifan will also connect with the creator platform and preset various high-quality sounds. These high-quality sounds will be launched in stages and can be OTA.
Feifan F7 places auditory comfort in a very important position and creates a more interesting experience. It is indeed a more avant-garde and trendy gameplay compared to other models.
Another core of comfort must be related to the seat. For this reason, Feifan F7 has conducted in-depth research on the pressure bearing of the human lumbar spine and focused on optimizing the waist comfort of the Bach chair.
Through mechanical analysis, Feifan's seat engineering team believes that a "waist-friendly" seat can not only solve the waist problem, but also involves the support of the feet and calves, the seat back and Factors such as the angle of the seat cushion, the supporting capacity, pressure, and contact area of ??the seat cushion and backrest.
So when it comes to Feifan F7’s Bach seats, the four-way lumbar support adjustment and a total of 70mm of soft foam layer mean that it can fit the back curve as much as possible; and the 580mm long seat cushion, electric The leg rests and three layers of soft foam layers with a maximum diameter of 65mm simultaneously provide a larger seat cushion contact area. In summary, these ergonomic designs make the F7's seats more comfortable than those of similar models. This can also be clearly felt during the test drive, especially the wrapping feel and softness of the front seats are just right, so you will not feel tired after driving for a long time.
There is also a very beautiful optimization. Feifan F7 has conducted research on the vibration of dynamic working conditions and the frequency of human body intolerance (which can be simply understood as discomfort), and thus the seat and the The chassis has undergone overall spectrum optimization. To put it simply, by strengthening the structure of the 6 positions of the seat, the vibration frequency of the seat is avoided from the main intolerance frequency range of the human body, thereby achieving a more stable and comfortable riding experience.
In order to prove the effectiveness of these optimizations, Feifan also specially used this seat to obtain the "Comfort Star" certification from China Automotive Research and Development Corporation, making Feifan F7 the first model with improved pressure distribution** *Car models that received full scores in 30 sub-items.
Feifan F7 has four such comfortable seats in the front and rear rows, and they are all equipped with heating and ventilation. The main driver has added electric leg rests and "zone-controlled" Hot stone therapy" function. Let passengers in the front and rear rows enjoy unified comfort, and everyone deserves to be valued.
? Is it comfortable to drive?
All Feifan F7 series are equipped with a rear axle motor with a maximum power of 250kW and a peak torque of 450N·m. The four-wheel drive model is also equipped with A 150kW, 250N·m front axle motor is installed. The rear-wheel drive model accelerates to 100km/h in 5.7 seconds, while the four-wheel drive model accelerates to 100km/h in 3.7 seconds.
For a comfort-oriented car, this kind of power is a bit excessive. You can find infinite driving in Feifan F7's driving modes. The performance settings are comfort, standard and sport, or it can be set to "adaptive" mode, which means that the vehicle will automatically adjust the power response state according to your driving habits. It’s really good news for users who have difficulty choosing, and the actual power response can meet the needs of most people. After all, the absolute power data is there. During most of the test drive, I set it to adaptive. As long as I was willing to step on it, the power never let me down.
Feifan F7 is equipped with the Onebox electric braking system as standard. The braking response time is only 150ms. The foot feel is easy to step on. The pedal stroke is also very linear. The depth of the pedal and the strength of the brake are different. Very good fit, no need to adapt.
High-end models are equipped with Brembo four-piston calipers, while mid-range and low-end models are equipped with ordinary four-piston calipers. I briefly test drove both models. In daily walking, the difference in foot feel between the two is not obvious. Only when braking suddenly at high speed, the braking distance is significantly shortened to realize the superiority of Brembo.
In short, ordinary brakes are enough, and Brembo will give you more confidence.
The Feifan F7 also offers three options: relaxed, standard and calm. Easy is more friendly to female users, but for men I recommend Standard. The steering feel in calm mode is a bit sticky, so I don’t recommend it. The steering of Feifan F7 has speed gain, which means that the steering wheel will become heavier after you drive at high speed, reducing the possibility of human error.
NVH quiet performance is an important indicator of comfort. Feifan F7 can give a high score overall. First of all, thanks to the ultra-low wind resistance coefficient of 0.206Cd, its wind noise suppression starting point is even better. Secondly, the front hood slits, wipers, front windshield, front triangle window, front side window glass, front door sealing system, Engineers have made extensive optimizations in the 10 key areas for wind noise including the rear side window glass, rear door sealing system, rear fixed triangle window, and hatchback tailgate, thus reducing the overall wind noise index of the Feifan F7.
In terms of road noise suppression, Feifan F7 uses ultra-high rigidity wheels. The wheel hub stiffness reaches 73E, which is 20 times higher than the mainstream wheel hub stiffness, effectively reducing the road noise index.
Feifan F7 has also carried out a series of targeted optimizations on the motor components. By optimizing the structure of the integrated motor, the motor can operate in an ultra-quiet state. I also felt this clearly during the test drive. The motor whine of the F7 is indeed very small.
The comfort of the chassis, the F7 is unexpectedly excellent, and it was the most amazing thing during the test drive. You might guess whether air suspension or CDC electromagnetic shock absorbers are used, but they are not.
F7 is a double-wishbone and multi-link suspension with a traditional mechanical structure. The technology and hard work we can talk about are mainly Vibach hydraulic bushings and Tenneco's high-end MTV CL series recovery spring shock absorbers. Combined with the Michelin PS EV tires, all three have obvious anti-vibration effects on longitudinal impacts.
This test drive was specially arranged to enter SAIC-GM’s automotive testing ground in Guangde. We drove the F7 on a medium Belgian road (a typical convex and concave bad road artificially built with granite stones. This road is derived from the stone road in Belgium, which is named as a representative of the typical bad road). The left and right sides of the car body The swing amplitude is not large, the suspension rebounds quickly, handles severe bumps relatively cleanly, and the chassis is not loose, and the integrity is very high.
When driving on public roads, the advantages of this good foundation are even more obvious. While retaining a slight road feel, the softness is just right. It does not have a floating feeling like Ji Krypton 001, but is more resilient. Another benefit of this toughness is that passengers are less prone to motion sickness.
This conclusion once again proves that don’t be obsessed with hardware, the adjustment level is the most important.
? Test drive summary?
Feifan F7 is more comfortable in both static and dynamic orientations, and does not bite off more than it can chew like other models, which is a smart approach. At the same time, it is also limited by hardware conditions (mechanical chassis), which is both necessary and obviously inconsistent with the laws of physics.
Under the existing conditions, the hardware is adjusted to the best state, showing a comfortable effect that is not inferior to air suspension and electromagnetic suspension. It not only adds points to the product, but also saves a certain amount of manufacturing costs. , which is more conducive to the final pricing strategy.
And in terms of smart driving and car-machine systems, Feifan F7 simultaneously uses the 8155 chip and Yingwei
