sorry for being off the topic, but will there be a big difference in 0-60 with 4 people rather than 1 in a 550i or 545i.
You must be an engineer right....oh snap

it seems that a lot of people think 5 series are really heavy due to size compare to 3 series.
My 545i according to spec, it weigh 3800 and 2009 335i sedan weigh 3600lbs(3594lbs to be exact)!!
If I drive alone in my 545i and 335i has an adult passenger in the car, the weigh is pretty much equal!!
That's why 535i is just as fast as 335i despite 335i owners think they can own 535i anyday of the week.

im sorry for not being as well informed, both of you guys are correct and the 545i is about the same weight as the e46 m3 convertible which i am really impressed by.... i do agree with miguex in this case since it seems to be the only difference... horsepower is for top end speeds and wouldn't affect much with it only being 5 horsepower which most of us would add right away with a simple intake... and the difference in torque is crazy between the 545i and the m3 which the 545i winning so my guess is that the only thing that the m3 would have over the 545i is the higher revs and the LSD.... the question is would the way higher torque of the 545i be able to overcome the high revs and the LSD!?!? i think it might be on the driver on this one.

they're 2 completely different cars aimed to different people with different style of driving
i myself have been thinking on purchasing one of this cars soon and i haven't been able to find the answer as which to buy yet
they're both in the same price range
the m3 has slight more horsepower and is way lighter but also has WAY LESS TORQUE in comparison to the 545i
the only reason the m3 is faster from the start would be because of the weight that the 545 has to make up with the torque that it has...
IT WOULD BE DEFINITELY A VERY CLOSE RACE AND WOULD DEPEND ON THE DRIVER MOST OF ALL
i love both of this cars and i am leaning more towards the 545i due to the fact that is newer and has more technology and is more sophisticated looking than the m3 which has a more sportish look i honestly wish i cud have both

Having said all that, I sold the M3 due to back problems, had back surgery 3 months ago and once again I am trolling the ads for M3's
however if I have to go back in town (Boston) for my next job the M3 is out. IMO an M3 is useless and annoying as hell in bumper to bumper traffic.

Off the line acceleration and exit of slow corner?
LSD won't do anything at highway speed no?

I've had both cars as well and the one thing i know is that the quarter mile is the only
way to measure how fast a car really is.
Therefore the M3 will aways beet the 545 in the quarter
mile unless the M3 driver screws it up by missing 3rd or some other type of human error.
There's a .5 second difference between the two and that usually means about 5 car lengths.
If you've ever drag raced your car you know thats a lot.

Correct me if I'm wrong, isn't it LSD is useful on

The LSD is not just for cornering, there are more and won't give the car more HP.
"The Quaife torque biasing differential enables your car to accelerate quicker and corner faster. How? By getting the power to the ground smoothly!.
The Quaife's unique design offers:
* Maximum cornering traction
* Improves handling and steering in all situations
* Puts the power where it is needed most, the wheel with the most traction!
* A definite advantage whether on the track or on the street.
* Quieter and less maintenance than a clutch pack style LSD"
