什么极端情况，电池这个东西没啥好说的，特斯拉他自己也不产电池，深圳比亚迪最早一批出租车跑了多少年，电池寿命就不是个大问题，现在电池更关注的点是能量密度以及安全，而并不是寿命。
至于乘客安全这种事，如果有数据支持说统计上中国车车祸死亡率就是明显高于其他国家的车，这TM才有说服力，否则你两个小嘴皮子随便一叭叭，看着大义凛然的样子，拿数据说话好吗？
当然了，有数据你又可以说中国造假数据不真实，哎，胡同截驴两头堵，咋说都是你对。
另外，不用拿一个截图就搞得好像揭露了一个什么偷工减料的行业黑幕一样
塑料齿轮这个概念是不是只有中国汽车厂为了你所谓的偷工减料降成本提出来的？
如果是，是哪一家中国车厂的哪个型号的车用了塑料齿轮，导致了什么问题，拿一个截图混淆视听，这到底是坏还是坏呢？
关于塑料齿轮，随手放狗一搜就能看到的一家西方供应商对于传动系统塑料齿轮方案的介绍，做汽车传动系统塑料齿轮方案的厂家不止一个，而且很多是外国公司， 为啥你拿到那张截图的时候不去验证一下？这符合你一贯风格吗？你都能从reddit英文版上找到比亚迪生锈，我相信用英文查个塑料齿轮对你不是难事儿吧？我是说你坏呢，还是坏呢？

中文版这个网站也有

下面是Victrex这个网站对聚合物塑料齿轮的说明，它说一家主要欧洲汽车制造商已经采用了他们方案，还和美国的主机厂客户OEM了其他项目，这个是不是可以按照你的逻辑说明全世界都在偷工减料？
VICTREX™ PEEK has been used in auto gears for decades but since 2015, Victrex has extended its material expertise to the design, development and manufacture of gears, to offer a fully integrated and highly innovative approach to thermoplastic PEEK gear solutions. Enabling Tier 1/OEM customers to work with one partner from concept to commercialisation, the company supports the development and testing of high-precision VICTREX HPG™-based gears, as well as manufacturing these gears as a component for integration into larger systems, e.g. within the engine, transmission, pump, actuator and chassis.
“Attaining this certification was a major goal for us. It unequivocally demonstrates that Victrex has the quality systems and capability to supply turnkey PEEK gear solutions into the mainstream Tier1/OEM supply chain”, explains Andy Walton, Director Automotive at Victrex. “A major European car manufacturer has already taken advantage of our gear design approach, as our ability to look at the whole system, not just the gear was invaluable. We are also working on numerous other programmes with global OEMs in other geographies, including the US.”
Victrex´s gear solutions include high-precision gear design, prototyping, testing and manufacturing capabilities using VICTREX HPG polymers. Compared to traditional metal-based gears, VICTREX HPG-based thermoplastic gear solutions for ICE and Electric Vehicle Platforms offer decisive benefits such as improved NVH (noise, vibration, harshness) performance as well as enhanced efficiency reducing CO2 and system cost reduction.
Victrex, which started as a PEEK polymer producer, has continually built upon its material, processing and industry know-how, as well as partnerships with processors and OEMs, putting innovation into action to solve existing challenges. In addition, the company is driving adoption and acceleration of new product solutions such as the gears offering. Today, millions of parts based on VICTREX PEEK polymers, forms and parts are at work in automotive applications, contributing to deliver cost-effective solutions that improve reliability, reduce recalls, and increase warranty periods.
Victrex automotive solutions including gears on display at K-show in October
At K 2019, the world´s leading trade fair for the plastics and rubber industry (October 16 -23) in Düsseldorf/Germany, performance, power and progress will also take centre stage at the Victrex booth (hall 5, stand B 09) and in the automotive section. Several Meet-the-Expert sessions are scheduled on the Victrex booth, including one on “VICTREX HPG™ gear solutions for future powertrain applications”, with Ralf Weidig, Global Program Manager Gears at Victrex, on Monday, October 21st, 17:30 CET.
High-performance PEEK polymer supports multiple requirements
PEEK polymer is a member of the PAEK (PolyArylEtherKetone) group of polymers and regarded as one of the highest-performing thermoplastics in the world. It is ideally suited to extreme and demanding environments. Whilst alternative materials can meet specific needs, PEEK polymers support multiple requirements with their inert properties, including light weight, high strength, and high resistance to wear, high temperatures, fatigue and aggressive chemicals. Together, these contribute to enhanced fuel efficiency, extended part life, greater comfort (smooth operation, less noise), more design freedom and greater cost efficiency.
* PEEK or PolyEtherEtherKetone is a member of the PAEK (PolyArylEtherKetone) group of polymers.
** IATF 16949 is an International Standard that assesses quality management systems to ensure: continual improvement; effective defect prevention; reduction of variation and waste in the supply chain and also includes specific requirements and tools for the automotive industry. It defines the fundamental quality management system requirements for automotive production, service and/or accessory parts organizations.
