To B-Post or Not to B-Post in a coupe.

[GTA45E]

What are your thought on B-posts in coupes. I personally don`t like B-posts in modern coupes because thay breakes the flow of design.

Technically speaking I also believe there are more efficient effective ways
to have a strong rigid body structure in a coupe besides using b-posts, So does Mercedes-Benz. Thats my opinion, what do you think.

Are B-Posts really necessary in todays style conscious cars?

 

[Zafiro]

I dont care at all, I just drive and enjoying the design. B pillars or not, I dont even think about it.

 

[GTA45E]

I think it makes the car look more upscale a good deal!! Come to think of it there is not one Mercedes 2-door car that uses a B-Post. Yet the body structure is very rigid and strong!

I thing MB secret is it`s think C-Pillar designs.

Look, there's nothing not to love about the sleek, unbroken look of a coupe with no b-pillar. However, there's an ovbious reason why BMW sticks with 'em, so I don't know what's to debate.

It's not a question of aesthetics, it's an engineering issue.

I believe if it were an issue (or necessity) Mercedes would use them, but thay don`t! Yet the body structures are just as strong if not stronger than BMWs.

Right.



Can we knock it off already with the b-pillar stuff? BMW makes performance-oriented cars, that's why they have the b-pillar. Sure, you can have a very rigid body without one, but with one the body is more rigid. Hence, the b-pillar.

I suggest we send emails to BMW and Mercedes and ask them.

You can believe that fairies dance on the heads of pins if you like. What you're suggeting is that MB engineers have discovered a brilliant technique for achieving stiffness sans b-pillar that BMW isn't privy to. That's nonsense.

An ultra stiff body isn't a necessity, it's just preferred. The CLK is a more luxury oriented kind of car than the 3er, and sports a larger rear seat, so it seems natural that it's sans b-pillar. They're just cars with different personalities.

Believe it or not, I`ve read quit a few areticles about torshional twist in the M3`s body structure. I have not read one complaint about the CLKs structure with twist problems, it`s no joke!!

What do you mean, I dont understand? What problem because I never heard of it.

Torshional twist is body flex when the car goes through fast lane changes
or hits uneven bumps in the road. It`s bad to have this in a performance car.
The Corvetter ZO6 also suffers from this problem!

why is it bad, is the car going to be cut in two pieces if you drive to fast in courves?

 

[GTA45E]

Right.

Nice pic of the C coupe. I was refering to the more upscale models. I should have made that clear!

No, its not that extreme! but it does show a weakness in the chassie!
which is not good!

ok, but if it really was a major problem it would be fixed and I doubt it has to do with B-pillars. M3 is a great performer and despite its age its still a great handling machine and not a death trap.

 

[GTA45E]

The M3 convertible is even worse than the coupe, it shakes badly through turns! Hopefully BMW addressed this problem with the new model.

Well the B-Pillar is supposed to help resist torsional flex because it acts like a support column. But as I said the new 3 should be improved.

now you exaggerate , I know people with M3 convertibles and I never heard a complaint like you said, also Sportauto has test the car several times on tracks and they have never mentioned it.
I hope you are aware that you sound like a BMW basher, an extrem one. Shame on you GTA.

I want to read about this cause I never heard it. Link??

hehe! I`m not bashing. If you want proof I can post a link to an M3 convertible test where the testers noted torsional flex.
