最近有时候真会觉得，物理学是不是不存在了。 如果你是个老车迷，那你大概率听说过发动机热效率这个参数。它和一台车的油耗高低息息相关，也是燃油车最最核心的技术指标之一。 同时你应该也知道，这玩意提升起来也非常困难。为了把发动机的热效率从 30% 提升到 40% ，全球的汽车工程师花了 50 年。 往上每提高一点都会被当成工业奇迹大书特书，此前的工程师们燃尽了所有手段，也就只能让量产汽油发动机的热效率做到 45% 。 热效率 45% 的玛莎拉蒂海神发动机 结果到了近一两年，新车们特别是国产混动新车的发动机热效率，开始坐火箭似的上飙。从 43% 开始一路飙到 45% 往上，到现在没有个 46% 甚至是 48% 都不好意思出来宣传了，全球最高热效率的名号也是一天一换手。 虽然看着很得劲，但多少有些反直觉。 如果热效率能升的这么快，那之前的工程师们都在忙活个啥劲呢？难道咱们的车企也去月球用烟头烫了外星人了？ 就连理想的高管老汤哥都有点看不下去了，也在前一阵发了条微博隐晦地吐槽了一波。 | 老汤哥Tango · ED | | --- | | 10-23 22:07 来自 iPhone 14 Pro Max | | #跟着老 ...
