5-link rear suspension. Is this why it feels so good?

I have nearly 9k miles on my car and I'm still amazed at the way it handles. It was great from the beginning, but I feel like it's gotten better. Or maybe I'm more in tune with the car and can feel the car flow through a curve.

I remember when the salesman told me that "the new 5 link rear suspension is really amazing" and I remember thinking, I'm sure it handles better than the old one, but to notice an extra link in the rear suspension? I think he was right!

Does anyone else feel like the car, how do I phrase this, follows you? It almost feels as though is has 4 wheel steering. I know it doesn't, but it settles into a curve and it feels like the rear end slides or accomodates itself along with the curve.

I find myself swaying from side to side even when I'm on a straight road just to feel the back play this trick. It's awesome.

I was a little skeptical about the improvements over the e46, which I used to own. I didn't like the shiftiness on the hightway caused by the sports package and I felt the e46 was more solid, but after owning this car for 4 months, I must say that I'm convinced that it is an amazing handling car and I don't regret my payment whatsoever.

Let me know if I'm crazy and I'm the only one feeling this in the rear. I don't know how to better describe it or if it is caused by the 5 link suspension. Does anyone agree?

I don't disagree. What ever that's worth.

But is this sway a result of the 5 link set-up? Can someone explain the new set up and why it has 5 links? Is this why it "follows you?"

Thanks. Just trying to learn something about the new car.

The larger Series cars have a 4 link suspension. I think as a general rule, if there are more links it gives the suspension that much more ability to absorb the road's irregularities. I think what you are feeling has more to do with the integrated design of the multi-links and how they actually attach to the subframe. Take a look at the suspension from the back of the E90 vs an E46 and I think you'll see what I mean.

Considering the 3 is their biggest seller, BMW probably decided to wait for this car before putting the design into production. I'm sure the other Series cars will get some version of this eventually.

I thought the 5 series has the 5 link rear suspension.

...and perhaps the weight distribution all attribute to how the car handles

As you probably know, the E90 doesn't get Active Roll Stabilization, while the 5 & the 7 do. I think that BMW is working on some way to incorporate ARS into this type of set-up. Probably costs them a lot more to use both.

5 series only have 4 links. The 5 links rear suspension design is very new, and I expect BMW will apply it to the newer 5.

Funny you should mention this ... I do this very often, on a straight road... and it's usually after exiting one of my favourite bends on my way home... I do it to "re-play" the sensation just felt at the real bend.

Honda Accord had rear 5-link suspension since 1998.

Yeah but that is front wheel driven, which makes it much easier to build and work good.

I think if the rear end of the car was not following it's front end, we'd all be in a lot of trouble...
