Weight of E46 M3

Hi,

I'm curious about actual weight of E46 M3. Has anyone of you weighted your car on a scale?

Today, while I was looking at my friend's M3 Manual book, I saw the weight is 1570 kg which I read on several car magazines but the manual also says 1570 kg with a driver (75kg) and 90% fuel tank without any option.

I weighted my E36 M3 EVO once which had alum. doors, no sun roof, no harman kardon, no electric rear windows etc. I just had electrical heated leather seats and the car weighted 1460 kg without a driver and with 1/4 fuel tank.

This means actually E46 M3 is not that heavy IMO. My E36 M3 was one of the lightest examples out of my friends M3s.

40L of fuel should weight approx. 30 kg + 75 kg driver = 105 kg and there we have a 1465 kg E46 M3 without any option. It is not bad. Am I missing something??

I guess, electrical heated leather seats add another 20 kg
sunroof should be around 10-15 kg
SMGII is 9,5 kg
harman kardon should be 5 kg atmost
My point is even with all the options, car should weight approx. 60-70 kg more which is reasonable I think.

What do you think??

These are in lbs for a fully optioned car (smg, HK, xenon, sunroof, power heated seats,...) ~ 1/4 tank of gas

FL 878, FR 850
RL 791, RR 873

These are before I adjusted the corner weights to balance it.

Total 3392 (No driver)

Thank you Enigma. 3392 lbs is ~ 1540 kg.
Which model year is your car? I read that 2002 models have lighter parts in bumper area saving some weight.

Ok, here is another data taken from E46 M3 Message form, I found it on Loki's Page:


" This summarizes the results of the M3 weigh-in I organized a couple days ago.

Process:
We met and filled our gas tanks immediately prior to the weighing. We also noted (and adjusted for) windsheild washer fluid levels and removed loose objects from our cars. We weighed the cars sequentially on the same pad at a "certified accurate" commercial scale.

Cars:
Five M3s attended. In particular we had two 2002 coupes, two 2001 coupes, and one 2002 cab. None of the cars had any accessories or modifications. The full description of each car is in the table at the link below.

Caveat:
Despite the scale being "certified accurate", it is somewhat imprecise. In particular, the scale reports weights rounded to the nearest 20 pounds. In other words, subject to the scale really being accurate, each reported weight is accurate to within +/- 10 pounds. Accordingly, each reported weight difference is accurate within +/- 20 pounds.

Discussion of Results:
Please go to the link for complete results. Of course, we didn't have enough cars or dispersion of options to infer all the individual weights, but some of the highlights are:

My "stripped" car, with only leather and SMG (and PDC) weighs 3,400 pounds. This is disappointingly high in that the owners manual states that the "curb weight (with one person, ready for operation, full tank of fuel, options not included)" is 3,415 pounds. This difference may mean that the scale is not perfectly accurate. Considering that SMG supposedly weighs about 18 pounds, I expected my car to weigh about 3,300 pounds (without driver).

Again for my car, the weight on the front wheels is 1,720 pounds while the weight on the rear is 1,680pounds. Our cars are nicely balanced. Also, note that I weighed the front and rear simultaneously, on adjacent pads at the scale. In that the individual pad weights equal the total weight on the first pad, this suggests that the scale is accurate.

Nick's "loaded" 2002 coupe (with the power seat package, moonroof, SMG, heated seats,leather, and Xenons) weighs 3,460. I am surprised that power seats (with lumbar and back width adjustments), moonroof, heated seats, and Xenon lights add only 40-80 pounds, collectively.

George's and Dom's 2001 coupes also weigh 3,460 pounds. Their options are similar to those on Nick's 2002 coupe. Of course, they lack SMG. But they both have the HK stereo. If we assume that the SMG/PDC option adds 20 pounds and that the HK stereo adds 10 pounds, a 2002 with the same equipment as George's and Dom's 2001s would weigh 3,450 pounds. Allowing for the scale's imprecision, the carbon bumper supports on a 2002 "save" -10 to 30 pounds. Am I right in thinking that the carbon bumper supports are the only weight-relevant difference between 2001 and 2002 M3s?

Kit's 2002 cab weighs 3,760 pounds. Comparing that to Nick's cars, a cab weighs about 280-320 pounds more than a similarly equipped coupe. Comparing that to my car, an option-free cab weighs 340-380 pounds more than an option-free coupe. "

Australian BMW web sites quotes the M3 weight at 1525kg
Japanese BMW web site at 1560kg
Canadian BMW web site at 1549kg

M3 CSL according to Japanese BMW website weighs 1430kg

Do all BMW dealers around the world calculate the weight according to BMW AG?

90% fuel tank + 68 kg driver + 7 kg for luggage + standard trim

My car: '03; options - Premium Pkg, 19", heated seats, Nav, 6-speed.

Aftermarket: Brembos front & rear, Eibach sways, AA exhaust, Ground Control coilovers, 45 extra pounds of stereo equipment in the trunk.

Weight with 1/4 tank of gas: 3415lbs

This was with no real weight savings involved. I corner-balanced the car and this is what was the result.

3415lbs that's approx. 1555kg, which is way, better than I thought; considering the options he has on his car plus the sound system.

CSL is 110 kg lighter than standart M3. BMW AG quotes M3 as 1570 kg (90% fuel tank + 68 kg driver + 7 kg for luggage + standard trim ). On the other hand, because of marketing purposes BMW AG quotes CSL as 1385 kg (without the 68kg driver + 7 kg for luggage) Try to make an impression that CSL is almost 200kg lighter.

HIPAD,

Actually E46 M3 is not significantly heavier than E36 M3 EVO (3.2L euro spec) On the BMW manual E36 M3 coupe quotes 1515 kg and E46 M3 quotes 1570 kg.

A fully loaded E46 M3 weights around 1530-1540 kg with 1/4 tank.

Onur,

As you said the M3 CSL is quoted at 1385kg, however the weight is calculated with 75kg for driver and luggage. I think the 90% fuel tank is the only missing part. But that's 185kg less than standard M3!!

You can check it here. Maybe it's a mistake?

"Weight of car in road trim (DIN) plus 75kg for driver and luggage" Unless they mean 1385kg plus 75kg, which is 1460kg
