胎壓打高真的能讓電動車省電？Tesla Model 3 上路實測 42psi vs. 38psi 電耗差異::DDCAR 電動車

大家知道電動車比較重，胎壓都會打高一點，例如特斯拉 Model 3 原廠就建議打到 42psi，在特斯拉車主手冊裡面更明確寫到，若要最大化里程，輪胎建議都使用建議胎壓。

只是說，Model 3 打 42psi 其實會讓路感很跳，很多車主 (以及車主的親友) 都說坐了不舒服，但心裡又惦記著「胎壓高比較省電」，最後就只好就這樣忍著彈跳感繼續開下去。

但是，到底胎壓高低會影響電動車多少續航？車主犧牲了一些舒適性又換到多少省電效果？難道真的沒有中間一點的選擇嗎？

今天我們就用 Tesla Model 3 SR+ 來實際測試原廠建議的 42psi 胎壓和開起來很舒服的 38psi 胎壓，在一樣的行駛條件下電耗差距有多少，看完你就知道該怎麼在省電和舒適之間取捨了～
