特斯拉 Roadster 用 SpaceX 風扇技術示範 2G 下壓力倒著開與不到一秒加速
原片標題:NEW TESLA ROADSTER - It Can Fly!!! (SpaceX Technology)
原片說明
Hi guys! The next-generation Tesla Roadster is finally here. Almost nine years after the first prototype broke cover, Tesla’s electric supercar returns with jaw-dropping specs: 0-60 mph in under one second, an underbody suction fan delivering 2 g of grip, and SpaceX thrusters. Long delayed and highly anticipated, the 2028 Tesla Roadster aims to rewrite what a sports car can do.
Tesla Roadster Specs and Performance
Sub-One-Second 0-60 MPH
Tesla claims the Roadster will hit 60 mph in less than a second, a figure no production car has ever achieved.
SpaceX Thruster Technology
The car borrows hardware from Elon Musk’s rocket company. Tesla even claims the Roadster will be able to fly, a promise that has yet to be proven.
The Only Tesla Built for Drivers
While the rest of Tesla’s lineup moves toward full autonomy, the Roadster stands apart. According to Musk, it will remain the brand’s only manually driven model over the long term. Tesla plans to make the most of that: since this is the one car built for people who love to drive, the goal is to push it to the limit and beyond.
An Underbody Fan That Sucks the Car to the Road
2 G of Cornering Grip
The Roadster’s wildest feature sits beneath the floor. A suction fan system actively pulls the car down onto the pavement, allowing up to 2 g of lateral force in corners. Tesla says the result looks like the car is defying the laws of physics.
Built to Break Track Records
Musk isn’t holding back: he says the Roadster will smash every track record ever set, outperforming anything today’s sports cars can deliver.
New Tesla Roadster Release Date
Production of the new Roadster is scheduled to begin in 2028.

「這車真的會飛?」我原本也覺得是嘴砲,結果馬斯克直接搬 SpaceX 的技術上來,還說要讓車子吸附在天花板倒著開。整支影片就是看他一邊示範吸力、一邊把 0 到 60 英里壓進一秒內,最後還留了一個懸念沒說完。

影片時間軸
- 01:11開場引用 Peter Thiel 的話,說未來承諾會飛的車卻只給了 140 字元
- 01:32講解車底吸氣風扇能產生 2G 下壓力,讓車子倒著開
- 02:07說明下壓力在賽道過彎的實際好處,能像無視物理一樣貼地
- 03:00示範「kickflip」,車子靠吸力做出翻轉動作
- 04:01切換高下壓力與低風阻兩種模式,風扇也分低速吸地與高速導流
- 04:44被追問加速秒數,改口說是「不到一秒」,並宣佈 2028 年量產
- 05:03結尾預告還有一件事沒講,準備揭曉最後一個驚喜

車底那顆風扇才是主角
整支影片最瘋的不是加速,是車底那套吸氣系統。官方說能拉出 2G 下壓力,把車吸在地上甚至倒過來貼天花板。聽起來像玩笑,但講到賽道就正經了:下壓力越大,過彎越穩,快到像在無視物理。這段把「很鬧」跟「真的有用」接在一起,是整支片最有說服力的地方。

不到一秒,跟 2028 年
被問到加速,講者先說「一秒」,馬上被糾正,才改口「不到一秒」。這種小地方反而讓人清醒:數字很狂,但講得有點心虛。量產時間直接押在 2028 年,離現在還有好幾年,中間會不會跳票沒人敢保證。片尾還留了一句「還有一件事」,擺明是要你繼續關注。
值得下載嗎:如果你只是想看一台車怎麼用吸力倒著開,這支值得存;但規格多半是宣稱,2028 年前都還只是紙上談兵,別當成已實現的技術來看。
覺得這篇筆記有幫助嗎?
