在Cybertruck 發佈會後不久,就有人懷疑這種造型會不會使得風阻值很差?
然後就有些人利用發佈會上的照片建立了模型去模擬測試
這是其中一張測試圖:

另外有些設計師也在影片中聊到這種造型其實並不差
最有名的例子大概就是F117 夜鷹戰鬥攻擊機
可以說非常的類似

這種造型並不會因為在後面製造過大的低壓區造成過大的空氣阻力
一般的皮卡在座艙後方通常會有很大的低壓區(深藍色部分)

唯一的致命傷就是相對來說平坦的車頭
現在Elon 針對這點出來說明Cybertruck 的風阻值可能可以達到0.30
這對皮卡來說應該是非常好的
一般的皮卡大多在0.45以上
2018年的RAM 1500 是0.36,被宣稱是同類皮卡中最好的
沒有公佈真正的數值應該是因為還有些細節像是後照鏡、雨刷等還沒確定
