After all the speculation about the performance difference between the 545 and the 550 before the 550's introduction, I am interested in the actual difference(s). I don't recall seeing any comprehensive reports from anyone who has made the switch from the 545 to the 550.
I was one of those who always thought that the performance difference would be minimal. I had ordered a 545 in the spring, then reconsidered when I heard about the forthcoming 550; I stayed with the 545, and I love it. Is there anybody out there who has upgraded and can report? Thanks. |

http://www.caranddriver.com/article.asp?se...article_id=9832 [/quote] Thanks much. For the 750i, the crudest of calculations gives: 330/360 (6) = 5.5. BMW's claim is 5.8. So, what we see is pretty much par for the course. Given the same sorts of about .3 discrepancy between BMW and the 545i, then the 550i will be exactly 5.5 - .3 = 5.2 to 60. :) I guess I won't do any regressions after all for 0 -60. :) I'll get back to you on the 1/4. :geek: |

Thanks for the replies, but to be honest, that is not what I was looking for. I have done the math too. Numbers can be misleading; for example my e46 M3 convertible smg has very similar acceleration and handling numbers as my 545, but they are very different cars.
I am interested in how the FEEL of the two cars compares. Is there anybody out there who has driven both (for more than a test-drive)? Thanks. |
