I weighed my M3

[rmashman]

FYI

Today I went over to the truck scales to weigh my new USA M3. Legally these scales have to be within +- ten pounds.

My car weighed 3570 pounds with a full tank of gas.

It was empty except for supplied equipment -mobility system etc.

Not as heavy as I feared, but no lightweight.

My car has a 6 speed, CF roof, 18 inch wheels, premium package, and EDC. But no nav, idrive, tech package and therfore no premium sound.

FYI: those are nowhere near accurate. we've had this same discussion about 335i when someone got a 3300 reading on the car. i'll search to link you, and he did it at one of the socal ones too haha

[lucid]

Actually that sounds about right without driver. C&D weighed it within the 3550-3600lb range if I remember correctly.

[MelsM3]

A full tank of gasoline, adds approximately 123 lb. and the E92 is supposed to weigh approximately 150 lb. more than the E46 [3,300].

[MrHarris]

Sounds accurate to me, great news.

[RandyB]

That sounds about right. It certainly doesn't feel that heavy to me while driving it, which is the important part. But it's no lightweight either.

To clarify: These were the Mayflower Moving Company Scales. They weigh the trucks before they are loaded and then after. The customers are charged the difference. These scales are calibrated by the State regularly so that customers are charged the correct amount. I have weighed cars there before and they have always seemed correct.

Actually most truck scales are in fact required to have a certain amount of accuracy. I would say that its probably within 50lbs of the actual weight...

if they charge on the difference then the accuracy is not that importantis it?

@OP: Great information glad you cared enough to go get weighed.

@mantis: Scales used for trade have to be certified to legal for trade accuracy. The so called NTEP classification. These scales will conform to that requirement. You can count on a very high accuracy typically better than .05% full scale. The individual load cells used in such a scale are probably abour 25k lbs. This means accuracy of about 10 lb or so. When you have your car on one of these scales get on and off it yourself and you will see that the difference is almost your weight, right on the money.

Isn't unladen car with full fuel and no driver? 3570 + 110 (100% full tank) = 3680. This puts the car within 25 lb (of options) within the spec of 3704 unladen.

I believe that the EU unladen weight, which is what the 3704 is based upon, includes 97% fuel, 68 kg driver and 7 kg cargo. So, subtract driver and cargo (165 lbs) and you get 3540 lbs, including fuel. I have no idea what options that weight includes.

[Epacy]

Excellent idea OP! Thanks for the contribution.

Not the worst weight at all.

Wrong, check your specs sheets and definitions. EU and unladen are not the same. There is no "EU unladen". 3704 is NA unladen.

ok - so he should drive on with a smart car and weight the two. then remove the smart car, wieght and calc the difference. yes?

[OzCarfreak]

add a 100kilo guy(me) xtra 220lbs , final m3 weight with x-middlelinebacker inside


3790lbs thaTS READY TO RUBBLE LOL

[skierman64]

As Lucid said in post #3, this agrees with what Car and Driver reported. For those that don't beleive, go weigh your car yourself.

There is an EU unladen weight standard. BMW say this:

Unladen weight: the figure quoted includes a 90 per cent tank filling, 68 kg for the driver and 7 kg for luggage. Unladen weight applies to vehicles with standard equipment. Optional equipment may increase this figure.


BMW US website quotes unladen weight as 3704 pounds for the coupe. But it also says "European Model Shown". This leads me to believe it's EU standard.

However, the bmw.com website quotes 1655 kg for the coupe, which works out to 3649 pounds. 55 pounds lighter then US unladen. I could be wrong but in the US is not unladen to mean without driver and luggage? Which would mean the US car is over 200 pounds heavier.

Now the sedan weighs 1680 kg EU unladen which is 3704 pounds. The figure quoted for US coupe. Coincidence?

Sorry you are correct on the EU/unladen thing. I was recalling earlier releases of information the said both simply EU and DIN, but did not mix EU and unladen. We need a clear definition of US unladen which I can not find.

It is a very interesting coincidence you noted that BMW EU unladen sedan wieght in kg converted to lb is the exact US unladen spec in lb. Seems like too much to be a just coincidence.

The "European model shown" is just a quote that literally means that the picture is of a European car. For instance sometimes you will notice that the pics on NA web sites or brochures do not show the ugly yellow front bumber cover reflectors which are std. in the US hence this verbage.

Overall I can not find any rhyme or reason comparing the EU to US weights for both Coupe and Sedan as well as the differences between them. Sure the Sedan is always heavier and US models are always heavier than the EU models but thoaw are about the only conclusion I can make.

[ersin]

I think the US model has more reinforcement for crashes. And of course those yellow reflectors add so much weight and drag it's unbelievable. It doesn't seem to hurt performance. 4.1 sec to 60 in both coupe and sedan. I don't see any better numbers coming from European reviews.

I believe the OP weights. So far, they are the only ones I have seen where we know what that weight includes.

I have heard of such differences existing in the past but I doubt those do today. Automotive companies are more and more global and they very much want to, and are, building global vehicles. For example BMW used to offer very different engines (at least hp wise and some major componenets) in the E36 M3. As well SMG I was available in some markets in the E36 M3. These changes and other dissimilarities have continued to decrease through the E46 and E9X models. I do think there are some minor intake/exhaust differences between the EU and NA E9X M3, and we know about the seat bottoms as well, but major structural/chassis/metal differences - highly doubtful.

The last comment is that many items that are optional (and paid for) in a EU spec car and standard in a US car. This will explain some of the differences.

All of these minor disagreements aside I do believe that the weight originally posted is accurate and reliable and again it seems to jive with the NA quoted numbers. In the past, based on some the the actual weights posted of EU cars I believed we would see US cars significantly lighter than US specs. That very well may have been wishful thinking on my part.

SMG i was NEVER offered on USA cars.
