僅節錄關於公差的這段原文
原文：
Most of the design tolerances of the Model 3 are already better than any
other car in the world. Soon, they will all be better. This is not enough. We
will keep going until the Model 3 build precision is a factor of ten better
than any other car in the world. I am not kidding.
Our car needs to be designed and built with such accuracy and precision that,
if an owner measures dimensions, panel gaps and flushness, and their
measurements don’t match the Model 3 specs, it just means that their
measuring tape is wrong.
Some parts suppliers will be unwilling or unable to achieve this level of
precision. I understand that this will be considered an unreasonable request
by some. That’s ok, there are lots of other car companies with much lower
standards. They just can’t work with Tesla.
針對公差這段話充滿疑問
DTS是Dimentional Technical Specification縮寫
GD&T則是Geometric Dimensioning and Tolerancing
一般車輛開發階段會制定DTS(如何定義，製造可行性也得考慮)
整車尺寸技術規範，像是車輛外觀(內飾、外飾件)面差、間隙等
以DTS為目標，分解公差後才會有個別零件GD&T，GD&T跟模具、夾具、檢具這些有關
供應商要做的就是依據車廠GD&T要求，提供符合的料件
車廠對供應商就是用這些GD&T作為驗收標準
而最終呈現在整車上的公差應該由車廠把關
換句話說
即便最後量產存在公差問題
只要供應商有符合當初車廠訂的GD&T，那根本就不甘供應商的事
而當初供應商沒有符合車廠訂的GD&T，那在驗收時就可以退件了
不用特地發言說供應商沒達到公差標準就滾蛋 (本來車廠也都這樣做XD)
所以嘛，不應該有車子量產後發現公差過大後把問題推給供應商才對
a factor of ten better than any other car in the world
另外也很頗好奇這10倍到底是?
