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![Cool](https://5series.net/forums/images/smilies/cool.gif)
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

the 545i and M3 e46 are about the same weight. I believe the difference of both that the M3 revs to 8500rpm and has LSD and 545i/550i revs to 6500 rpm and no LSD. Imagine the 545i revs to 8500rpm and LSD installed!

"Acceleration is better estimated by a comparison of torque, the engines twisting power, while top speed is a function of horsepower, or the amount of work an engine generates.
The 545i has 330 ft/lbs while the M3 has 262 ft/lbs. Advantage 545i.
Weight is more critical for acceleration than for top speed as well. The 545i 6sp is 3737 lbs and the M3 convertible is 3780 lbs. Advantage 545i.
Gearing for the 545i is (1st)4.06:1 / (2nd)2.40:1 and the Final drive ratio 2.90:1 the gearing for the M3 is (1st) 4.23:1 / (2nd)2.53:1 and the final gear ration is 3.64:1. Advantage M3.
It is conceivable that a 545i would out accelerate an M3 convertible. Also, on the street, driver ability would influence even identical cars significantly."

There is a interesting thing that BMW does not want us to know (about LSD):
"... The last production BMW to be sold with the option of a limited slip diff was the E36 328i. Since then, LSDs have been the
preserve of the fabulous M-Power cars. Unfortunately, those of us who choose a more comfortable but less extravagant and
focused BMW may well find that the standard power of the car easily overcomes the amount of traction available. This is
especially true with late cars, equipped with run-flat tires, and stiff suspension. For the first time, there is a cost effective option
for those who want to enjoy maximum acceleration performance without compromising safety or stability. We now offer the
world renowned Quaife automatic torque biasing differential for the entire BMW range. Be prepared to wonder why BMW are
not offering this amazing device...."

Pretty sure the 545 is about 4000 lbs. I think your weight is a bit off.

Take out the floor mats and you'll be beating Veyrons.

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.
