On December 29, 2023, SAIC Group’s Fevan brand’s intelligent and comfortable mid-size hatchback electric car, the Fevan F7, underwent a hardcore upgrade. The 1 billion Fevan Bay Domain driving system brings the longest 702km range, industry-first crosswind suppression, and more precise 4k-level linear control. The Fevan Bay Domain driving system also introduces a new soothing driving mode, using comfortable technology to relieve motion sickness without side effects. The highly praised Bach cabin has also evolved in this upgrade, with the Bach cabin digital ecosystem online, allowing users to experience the latest smartphone and car intelligence without changing their phone. The Bach cabin’s fully immersive experience has been upgraded, with iQiyi 5.1 surround sound, creating a HiFi-level private theater. The Fevan F7’s intelligent driving large model has been optimized, with further enhanced visual algorithms for a smoother and safer driving experience. The new narrow lane passing assistance function greatly improves narrow road passing efficiency and intelligent anti-scratch.
The F7’s driving system in the Feifan Bay area has a maximum range of 702km. The driving system, based on SAIC’s self-developed electric vehicle calibration system, took 3 years and 1 billion R&D resources to develop, completely integrating the three electric domains and the vehicle body domain. It is the industry’s first dynamic technology for cars that incorporates aviation concepts. This system increases the maximum range of the Feifan F7 series by 36km through battery management and electronic control optimization, reaching a maximum range of 702km.
The Bay Area Driving System also introduces the concept of aviation three-axis technology to adjust vehicle body control. This adjustment first achieves lateral aerodynamic optimization, creating the first lateral aerodynamic standard. After high-speed, overpass, cross-sea highways, or truck turbulence produces negative pressure suction, and driving during the typhoon season in coastal areas, even if the strong wind blows, the FeiFan Bay Area Driving System can achieve “no lateral wind, stable direction control, stable body recovery”. On the other hand, the system monitors motor data in real time through the rotary sensor, intervenes in vehicle posture control earlier, compensates for side wind through PDC steering, provides torque compensation for lateral wind, and ensures that the vehicle does not sway in the lane; always keeps the steering wheel stable and does not need continuous manual correction in continuous crosswinds, making driving safer and easier. Finally, the system is equipped with the Continental One-Box integrated electric braking system, and has a special adjustment ESP program for crosswind scenarios, with a super-fast response time of 200 milliseconds, three times faster than traditional ESP. In addition, the FeiFan Bay Area Driving System enables the FeiFan F7 to achieve linear power output at the 4k level in terms of driving control, with linear and delicate acceleration and braking pedal feel, and precise steering control. In addition, the new soothing driving mode effectively suppresses the dizziness caused by acceleration and deceleration, multiple bends, and bumpy road conditions, and advances the comfort of driving for people prone to motion sickness.
Bach cabin digital ecosystem loaded, users can enjoy smart interconnection immediately Bach cabin digital ecosystem, with immersive audio and video enhancement, has always been synonymous with intelligent comfort. The Bach cabin digital ecosystem, compatible with most mobile phone brands such as OPPO, VIVO, and Xiaomi, is currently the most compatible in the industry. Users can enjoy smart interconnection immediately without changing their phones, with nearly 50 popular apps synchronized in the car, covering most life and travel scenarios. Navigation information can be easily, accurately, and safely displayed on the screen by shaking the phone. With support for applications such as Amap and Tencent Meeting, the Bach cabin can instantly transform into a smart and comfortable mobile office.
The entertainment function of the F7 Bach cockpit has been greatly upgraded. iQiyi video supports 5.1 channels, bringing an immersive viewing experience; added front and rear video three-finger rotation, convenient for sharing the audio-visual experience with family and friends; the whole vehicle audio optimization delay and frequency response, making the sound field positioning more accurate, sound restoration more clear, and sound quality more realistic; the whole vehicle screen can use Leishi KTV, achieving multi-person multi-screen singing together.
Smart driving greatly improved, narrow lane passing assistance for users to avoid “scraping danger” In the latest upgrade of Feiyuan F7, a brand new narrow lane passing assistance function is introduced to address the pain point of frequent scraping in narrow road conditions. When driving at low speed through narrow or crowded roads, the large screen of Feiyuan F7 automatically activates the top-down/side-view camera, providing precise feedback of the side view, eliminating blind spots and improving driving efficiency and safety.
The RISING Pilot carried by the FeiFan F7 benefits from large model optimization and further enhancement of visual algorithms, achieving optimization in more scenarios. It enhances the risk scene recognition ability of lane control assistance and high-speed navigation assistance, improving the experience when merging into the lane with large vehicles or when two vehicles merge into the middle lane at the same time. It optimizes the speed control strategy of high-speed navigation assistance on the ramp, improving traffic efficiency. It also optimizes the navigation positioning performance, enhancing the continuity of high-speed navigation assistance usage. It improves the parking planning and control capabilities, increasing the success rate of diagonal parking and the centering performance of parallel parking. It enhances parking perception and recognition capabilities, improving obstacle recognition rate and safety.
Some software functions will also be upgraded to FeiFan R7 through OTA in addition to the entire F7 product line.
