: If this weight were to reside, say next to the driver, as in putting another passenger in the car, then the mass is so close to the center of the car that the force x distance would not result in much resistance to momentum.
: HOwever, in this case where the weight is displaced much farther than next to the driver, the force x distance away from the car's vertical centerline creates alot more resistance to changes in the momentum.
: Taken in another context, try to spin about with a bowling ball held close to your chest. Now do the same with the ball stretched out as far as you can away from your chest.
: : : i just picked up my new 2000 528i last wednesday; manual tranny; jet black with black leather comfort seats; xenons; premium sport package; moonroof; sunshades. great car!!!
: : : i recently sold my 1997 540iA, which i only owned for about 4 months. I have been driving Bimmers for 25 years. i also ride motorcycles and have presently a Honda VFR800 motorcycle. I have owned various motorcycles, including BMWs, and the VFR800 is the best overall bike I have ever owned. i am very attentive to the handling, weight and "feel" of cars and morotcycles.
: : : HERE ARE MY THOUGHTS ABOUT MY NEW 528: the 528i is a much better car, in my opinion, than the 540, for two fundamental reasons. the extra 400+ pounds for the 540 fall virtually all on the front end of the car. thus, the 540 feels much too heavy to me, and almost feels like a front wheel drive car. i feel like i am being pulled by the front wheels of the 540, rather than pushed by the rear wheels of the 528.
: : : second, the rack & pinion steering in the 528 has a much better feel. i can feel the contact of the front tires on the road with the 528; i always felt detached from the road with the 540.
: : : sure, the 540 is faster. but, the 528 has a sportier and fuller character; a fine degree of refined rawness.
: : : this is just my view.
: : re: "400+ pounds" - While I don't doubt you feel some difference and apparently prefer the 528, here are the actual numbers from BMWNA
: : unladen weight:
: : 540iA(3803) - 528i5spd(3495) = 308 lb.
: : Perhaps a more fair comparison would be:
: : 540i6(3748) - 528i5spd(3495) = 253 lb.
: : Still the 528 has the weight advantage but not as many pounds as your post suggests. I am glad you like your wheels anyway!
: : Rgds,

Just a thought.
Weight distributions(% f/r):
540i/6 - (52.1/47.8)
M5 - (52/48)
While I think most would agree the 528i would handle better on a track or twisty roads, I'm not sure it's that dramatic a difference for the everyday 'real-world' drive that I'm accustomed to. I don't hear many complaints about the M5 performance which is only improved by 0.1% weight distribution-wise compared to the 540i/6. I guess the perfect beast is the M-coupe (perfect 50/50).
