LC車頭是引擎蓋彈起設計
用pop up hood, pop up bonnet, active bonnet可以找到滿多影片的

這類的引擎蓋會在偵測到撞擊時彈起，達到更好的緩衝效果保護行人
Vulnerable Road User (VRU) Protection

EU-NCAP對應行人防護有分頭部、大腿(骨盆)、小腿以及AEB幾種測試

NHTSA這篇文章也是在講Pop up hood對行人的防護
挑幾個結論來看
‧ Since 2010, vehicles with pop-up hoods generally produced better Euro NCAP
headform scores on average: 17.2(out of a possible 24) for cars with pop-up
hoods vs. 13.8 for cars with non-deploying hoods.
有引擎蓋彈起設計的對行人頭部防護能力更好
‧ Pop-up hood technology is generally more costly than other passive
strategies for protection pedestrians, but this examination of pop-up hood
trends showed that sometimes a pop-up hood can lead to lower HIC values
while enabling the vehicle to attain a better Euro NCAP score and still
achieving a desired vehicle style.
成本較高，但在NCAP分數也會更好
一般乘用車引擎蓋outer panel、inner panel大概約1mm內
引擎室設計撞擊時
1. 引擎蓋會向上彎折
2. 主要重量(引擎)下沉
3. 潰縮區吸能
力傳遞路徑：防撞橫梁 => 吸能盒 => 前縱樑

→ z85917131 : 輪都沒位移有點猛09/30 12:21
若前輪沒位移代表主要是靠吸能盒緩衝
至於RAV4，後廂結構有個鋁合金後防撞橫梁，再來就是C柱下方連接的橫梁了

一般設計上C柱以後的行李箱空間不太會用高強度鋼
