ผมเพิ่งไปอ่านเจอว่า รถที่ไม่ใช่แบรนด์ยุ่นก็มองเห็นข้อดีบางอย่างของ torsion beam และลองเปลี่ยนมาใช้บ้างเหมือนกัน (2018 A200)
-Benz A200 หันมาใช้ ช่วงล่างหลัง torsion beam เป็นครั้งแรก
เท่าที่อ่าน Program manager แกบอกว่าเพื่อลดน้ำหนัก (ลดไป 20kg) และจากการทดลองพบว่าไม่รู้สึกถึงความแตกต่าง
-Review road test ก็ออกมา ok ดีนะครับ

MERCEDES-BENZ A-Class program manager Oliver Zolke has defended the decision to ditch the multi-link independent rear suspension (IRS) of the outgoing model for a simpler torsion beam axle in some models, insisting that a comfort level befitting of the car-maker was achieved with the new geometry.
We had the same doubts (about torsion beam), we were really struggling whether to do it and we gave it a chance, and we were very convinced that we have the right system.
When you do a blind-fold test, put two of the same cars on the road and tell me which is the torsion beam and which is the multi-link, I cannot do it. We have a torsion beam axle for Mercedes comfort demands or comfort requirements.
You talk about cost, I talk about weight.It was weight reduction and it was also space, you save a lot of space for other components in the rear part. We try to match it to the engines and to the power, and of course to the weight.
