新车研发从55个月砍到26个月！日产高管：得照中国模式学_我的网站

一 |     8月25日消息，据报道，日产社长伊凡・埃斯皮诺萨表示，日产过往新车研发需要55个月，2026年冬季推出的新款Skyline研发周期将压到26个月。     同时，埃斯皮诺萨还称，中国车企在技术、成本控制与研发效率上已成为行业标杆，日产将主动学习相关经验。

二 |     近些年日产经营压力凸显，2025财年全球销量同比下滑6%，本土市场跌幅达到13%，2026年上半年本土销量更是创下数十年新低。         传统模式下，日产每款车型独立开发，多部门多头管理，内部沟通消耗大量时间，漫长的研发周期让产品落地时就跟不上市场的变化了。

三 |     借鉴中国车企经验，日产打算从三方面重构开发逻辑。一是推行家族化共享平台，不再每台车从零开发，一套架构可以衍生轿车、SUV等多种车型，同时精简组织架构，由项目总监统一统筹，减少部门内耗。

四 |     二是大规模落地AI与数字孪生技术，在虚拟环境完成大量碰撞、耐久测试，减少物理样车迭代次数，甚至实现夜间无人值守测试，提升测试效率。         三是采用并行研发模式，设计、工程、测试、供应链同步推进，替代过去一环接一环的串行开发方式。日产计划2026财年，让这套高效流程覆盖九成新车项目。    Dhaka, Oct 9 (UNI) Teesta is one of the 54 rivers that enter Bangladesh from India. After originating from Solamo Lake in India, it flows over Sikkim and West Bengal and enters Bangladesh through Rangpur region.

Later it joins the Brahmaputra river near Chilmari in Kurigram district. For many years there has been a demand for a Teesta agreement on the sharing of Teesta water. But the agreement is stuck due to India's delay and various excuses. Because of this, the people of the northern part of Rangpur Bangladesh are now dreaming about the Teesta Master Plan.

The Teesta Agreement was to be signed during the then Prime Minister of India Manmohan Singh's visit to Dhaka in 2011. But it stalled in the face of opposition from West Bengal Chief Minister Mamata Banerjee. Then in 2015 Indian Prime Minister Narendra Modi visited Bangladesh with Mamata Banerjee. There he assured that a compromise would be reached on Teesta water sharing. But the Teesta problem has not been solved.

During the last Bangladesh Prime Minister Sheikh Hasina's visit to India, there was a possibility of reaching a settlement on Teesta water distribution, but it did not happen.

In addition to the construction of various infrastructure related to Teesta coast management, flood control dams and various types of infrastructure will be built to eliminate water shortage during summer. Since Bangladesh has a long-standing dispute with India over Teesta water sharing, arrangements will be made to retain water during the dry season. Among the issues that have dominated the project so far, three are important—dredging the riverbed, revetment or embankment repair and embankment, and land reclamation. Apart from this, there are also plans to repair flood dams.

If this project named 'Teesta a River Comprehensive Management and Restoration' is implemented, a 220 km high guide dam, river drive, hotel-motel-restaurant, modern city and tourist center will be developed along both the right and left banks of the Teesta river. Along with that, 150 MW solar power plant, industrial plant, EPZ will be built.

Apart from this, several lakh hectares of agricultural land will be saved and afforested. Under this project, the main stream of Teesta will be two kilometers, which will maintain navigability throughout the year. It will be connected by several canals, which will benefit crores of people of Teestapar. It is said that the two banks of the Teesta will be modernized on the model of China's Huang Ho River and Suqian City through the master plan. There will be Marine Drive on both sides of the embankment. Modern irrigation projects and agricultural farms with machinery will be built. At the same time satellite cities will be built on both banks of the river.

The two banks of the Teesta will be developed on the model of Suqian City in East China's Jiangsu Province. For this, approximately 9 thousand crore taka can be spent. The project is named Teesta River Comprehensive Management and Restoration'. Since then, days go by, months go by, years go by and years come. However, the much-desired great plan has not started.

Chinese Ambassador Li Jiming visited the Teesta Barrage on Sunday, October 9.

At this time, he listened to the hopes and aspirations of the people of the area. A large number of local people, civil society and administration people were present.

It is noted that, Rangpur is the poorest division of Bangladesh. And five of the country's poorest and most impoverished districts are located across the ravaged Teesta. Pagla river famous Teesta Lalmonirhat, Nilphamari, Rangpur, Kurigram and Gaibandha districts is the name of the misery of millions of people. The flow of the 234-year-old Teesta is causing floods and droughts every year in these five districts. People's sighs are getting heavier because of this, the life cycles of both sides are constantly changing.

UNI BAV SHK1835。     不过研发提速并非毫无前提。国内车企24个月左右的开发周期，大多建立在成熟平台基础之上，依托现有架构做衍生迭代；若是从零打造全新底层架构，依旧需要三到五年时间。

五 | 这也意味着日产26个月的成果，同样依托成熟平台积累，并非完全从零开发。    研发提速的背后，行业也浮现出了新的挑战。

六 | 国内新车投放节奏不断加快，产品迭代过快带来保值率下滑，部分产品被质疑验证不足。

七 |     监管层面已经出手，将可靠性试验纳入准入强制要求，拟把新能源车型可靠性行驶试验里程提升至3万公里。速度是竞争优势，但不能牺牲产品可靠性，这也是包括日产在内，所有追求研发提速的车企都需要面对的课题。
