全時四驅對鋪裝道路的穩定性還是有影響的
先看看這篇文章再下結論
consumer reports
節錄其中一段
Is AWD safer? Not necessarily…
One of the reasons many people buy a traditional sport-utility vehicle is for the extra security and traction of four-wheel drive. Many drivers don't realize the limitations of AWD and 4WD, however. Though having power delivered to all four wheels increases straight-line traction, it does nothing to improve cornering or braking.
Drivers are often fooled when driving in slippery conditions with an AWD or 4WD vehicle, not realizing how slippery conditions may be when driving, only to discover they are going way too fast when trying to stop. Because the added traction of 4WD can allow a vehicle to accelerate more quickly in slippery conditions, drivers need to be more vigilant, not less. Slippery conditions demand extra caution, no matter what you drive.
In many cases, having good tires is more important than the drive wheels. Winter tires, for instance, actually do help you turn and stop on a snowy road—things that AWD doesn’t help with.
國外的測試結果,四驅對於過彎、煞車完全沒有幫助
(甚至可能因為車重的增加而影響過彎、煞車表現)
簡單講,有無四驅對於操控安全沒有影響
以台灣的地理環境還有天氣特性(不下雪)
不上山、下海的話,前驅車是最好的選擇
標準的輪胎比四驅較重要的論點,是的,這樣的論點基本上是沒有疑義的。
但此篇作者卻不提 "若同樣的輪胎" 且在 "同樣的速度" 的條件下,四驅與二驅比之又如何?
說的好像四驅車就不懂得用所謂的 good tires 似的,或者不會在冬天使用 winter tires 似的
而且刻意說四驅(AWD & 4WD)在過彎時會速度更快。。。那速度一樣可否,這樣的條件下四驅與二驅相比又如何? 作者沒提!
太過刻意設定的條件了
二驅的優點有許多,最常見的就是成本低且較省油,保養與維修的花費也相對較低
自然多數人會選擇。。。
畢竟車子作為代步的工具,大部份情況二驅是能勝任有餘的

他們有做過一個實驗
在雪地都使用一般胎,結果四驅、二驅煞停距離幾乎一樣
二款車再全部換成冬季胎,兩台車煞車距離同樣沒什麼差別,但都比一般胎還要縮短許多

為何會說四驅過彎時速度會更快,是因為在雪地時,四驅有四顆輪胎輸出動力,更容易達到預期的速度
,所以容易讓駕駛產生錯覺以為四驅車比較安全而用更快的速度通過彎道,卻往往因為這樣而發生意外。
