先說幾個心得
1. 相同車系，轎車剛性 > 天窗版&旅行車 >> 敞篷車
◇以Saab 9-3為例， (2008-2012年)
轎車22,000 > 旅行車 20,548 > 敞篷車11,500 Nm/deg
剛性分別相差了6.4%和47.7%。
◇BMW F25 X3 30,000 (無天窗); 26,000 (有天窗)，剛性相差13.4%。
◇VW Passat 旅行車 (B7 2010~2014) 25,000
VW Passat 轎車(B7) 30,000，轎車和旅行車的剛性相差18%。
◇Ferrari 458 33,120和Ferrari 458 Spider敞篷 23,184，
458 coupe和敞篷的剛性相差30%。
2. 同型車，性能款的剛性 > 普通款
◇以Golf 5代為例，Golf GTI的剛性比普通款強36%，差距很大。
(25,000 vs 18,400 Nm/deg)
2. 三門掀背車的剛性 > 五門掀背
◇Ford Focus 三門 19,600 vs 五門 17,900Nm/deg，剛性相差8.7%。
◇另以Golf 4代為例，3門款的剛性比5門強11%。(19,600 vs 17,600 Nm/deg)
4. 加裝防滾籠，能有效提升車體剛性。

5. 某些知名超跑的剛性不一定比平價車款強。
例如同一時期的 Lamborghini Gallardo(2003~2008) 23,000 就輸給Mazda RX-8
(2003~2012) 30,000Nm/deg，剛性相差23%。
6. 全部車款當中，剛性最強的是瑞典超跑Koenigsegg Agera R，高達65,000Nm/deg，
它的剛性是Ferrari 458 近兩倍 (33,120Nm/deg)。
轎車中，剛性最強的是勞斯萊斯 Phantom和賓士W222 S-Class，高達40,500 Nm/deg，
贏過賓利Flying Spur (2013) 36,500 Nm/deg，相差11%。

(圖) 勞斯萊斯Phantom，它和賓士W222 S-Class的剛性是所有轎車中最強的，
高達40,500 Nm/deg，還贏過賓利11%。

7. 某些敞篷車的剛性只有正常款式的一半，甚至更低，
◇例如Porsche 911 Turbo 996 (27,000 vs 11,600敞篷)，剛性相差高達57%。
◇Audi TT Coupe Mk1 19,000，TT Roadster 敞篷 Mk1 10,000，兩者剛性相差47%。
8. 高剛性 ≠ 高安全性
除了車身剛性以外，潰縮設計和分散衝擊力的設計也很重要。
新Volvo XC90撞擊測試第一名，但它的剛性數據並不是同級車最強的。
◇ 高剛性 ≠ 操控性
Alfa Romeo 159車體剛性比上一代Alfa 156強了近3倍，但Alfa 159操控退步，
評價大不如Alfa 156。
9. 車廠的用心程度，可以讓新世代車身剛性大進步
◇從數據中也能看到BMW世代交替的進步，BMW F世代的車身剛性比E世代晚期增強許多。
(圖右) BMW六系列，前後兩代剛性數據比較圖，F13世代的剛性比E63大幅增強65%。
F13(2011-) vs E63(2004-2010)

◇Mazda Skyactiv世代，車體有60%是高強度鋼材，大幅提升剛性。
(圖) Mazda CX-5車體結構圖，剛性27,000 Nm/deg。
Skyactiv世代大量使用高強度鋼材，比例達60%。

10. 同集團的平價品牌的車身剛性不一定輸給高級品牌
例如Golf六代 25,000，車身剛性超越同時期的Audi A4(B8) 23,100。
(圖) Golf 六代車體結構圖，剛性已經超越同時期的Audi A4

◇以下是各車廠車身剛性數據總整理 (Torsional Rigidity, Nm/deg)◇
這是由youwheel.com整理，絕大部份的資料是來自車廠公佈數據和雜誌報導，
一小部份是第三方單位的數據。
另外有幾種車款的數據是我增列的，來源大部份是網路上的原廠資料，
少部份是外國汽車論壇。
Alfa Romeo
Alfa Romeo 147 3-door (2000–2010) 16,600 Nm/deg
Alfa Romeo 156 (1997–2007) 11,000
Alfa Romeo 159 (2004–2011) 31,400
(圖) Alfa Romeo 159的車身剛性大勝同時期的同級對手，
甚至贏過晚了8年上市的BMW F30 3系列。
