Weighed: F80 basic stripper configuration - 3,450 pounds

BIMMERPOST
     Featured on BIMMERPOST.com
Hi all,

I've just come back from weighing my vehicle. Before you read on, know the context of these results.

Equipment of Vehicle
The vehicle is a 2015 f80 m3 with no options except m-adaptive suspension. That means 18" wheels, 6 manual trans, etc.

Carbon fiber roof

Fuel

The tank had 3 gallons in it INCLUDING THE RESERVE at the time of weighing. This was confirmed by filling up AFTER the weigh in and putting in 12.89 gallons.

Miscellaneous Items in Car

I removed everything from the vehicle not physically screwed down. No manual, no extra quart of oil in the trunk, no trunk net, etc.

Weight: 3,450 pounds

This was weighed at a scrap yard that charged me $4 to weigh the car. However, their scales are inspected and verified down to a narrow range because people are getting paid by the pound.

The scale read-out was, unfortunately, a type of readout that does not take photos well - it constantly flickered on my iPhone so I couldn't grab the full readout in any one phot. Here's the best verification I can offer showing the -50 pound ending: '



For comparison purposes, EAS weighed an M3 and M4 with much higher levels of equipment and with either an empty or full tank:

My take: I was expecting, with so little fuel, a lighter vehicle. From a driving perspective, it drives light and agile and amazing. As a "magazine racer", I'm dissapointed it's not ~50 pounds lighter than this.

Nonetheless, compared to EAS' F80 m3 weigh-in I can say that this vehicle weighs ~110 pounds less than a DCT, 19", carbon ceramic brake, exec pack, lighting pack, drivers assist pack, full leather model.

That's a decent chunk of weight considering the DCT vs manual was weighed to be closer to a ~40-50 pound difference, CCBs should be lighter or at least cancel out the 19" wheel weight difference....leaving I guess 60-70 pound weight gain for exec pack, lighting pack, drivers assist pack, and full leather.

I think we're narrowing down more on how much various options actually impact weight.

Good info. Thanks Joe. I have the same build as yours except MW.

Hey, how about the mobility pak in the trunk storage area. That's about 3 lbs 12 oz.

Carbon Roof, yep.

On a side note, I won't be doing business with my local BMW specialty shop who is a BMWCCA partner and very involved in the community. I had two phone calls with them, and they are literally ONE BLOCK from this scrap yard.

And they offered to weigh me for $75 for 30 minutes shop time and knew all I wanted was gross weight.

But I call up a Porsche specialty shop ~3 miles away and they recommend the scrap yard for a $4 gross weight weigh-in.

Pfft.

Nice!

Is the mobility pak screwed down in the storage area? If not, it was removed

(Hint: It's velcro'd down)

so......

6.0 x 13 gallons = 78 lbs. So full fluids weight is 3528

Correct, and this is why I think BMW is playing games with their weight figures.

This car should weigh 3,540 pounds equipped per BMW's website. Supposedly that reflects how most WILL be equipped, so a DCT car and maybe exec package, right?

Not so much.

HOWEVER, check this out: http://www.m3post.com/forums/showthread.php?t=295896

A very similarly equipped e90 m3 in 2008 with 3/4 tank of gas weighed in at 3,611 pounds.

So I'm guessing this car is about 120 pounds LIGHTER than an equivalently equipped e90 (4-door)

Edit: That e90 might have fixed rear seats, which saved another 30 pounds or so compared to fold down rear seats.

Thanks Joe for doing this. This is an important data point for future weight discussion. Thanks.

I think I read somewhere here that the 19" wheels are actually not much heavier than the 18" wheels. It may have been from and iND which they weighted both wheels. I think the 18" rim is lighter than the 19's, but the 18" tires are heavier than the 19's. So it was a wash.

According to BMW, the 6MT to DCT weight difference is 89lb.

I know, I'm referencing a weigh-in with nearly identical cars where the only difference was DCT vs. Manual. I'm not validating this information though, just repeating what I understood.

The 18s with tires, as a set, are ~7-8 pounds less than the 19s with tires.

However, the 19" tires are lighter than the 18" tires.

Therefore, the belief is that from a static weight perspective the 18s will weigh less but from a dynamic perspective, taking into account unsprung rotating mass, it's either a wash or the 19s are slightly advantageous.

Gasoline is about 6lbs per gallon. My fully loaded (except for EDC, CCB and Sunroof) F80 DCT with a full tank, ended up at 3574 lbs. 77.22 lbs for gas, means the delta might not be as large as you think.

I suspect that there are very few options that really add weight. EDC adds several feet of harnesses and sensors and the dampers are (slightly) heavier. The Driver's assistance likely adds a bunch of wiring for the cameras, etc.

Thanks Joe for the data point. I'm curious now what my non-sunroof 6MT E90 M3 weighs under similar conditions. I'm glad you mentioned all the stuff you removed from the car as I might not have thought to do that.

Forum member Richbot weighed his non-roof 6MT E90 with 3/8ths of a tank of fuel and got 3522 lbs. If he dropped to your fuel load, maybe that's ~15lbs, so that would get it down to 3507 lbs. He has the M performance exhaust though which is 20lbs lighter than stock, so that would put him back at 3527 lbs.

So things removed would include: floor mats, everything in glovebox, all nooks, trunk, mobility pack...what else?

One thing to realize is that BMW quoted weights of course include stuff like mats, mobility pack, etc.

Even still if Richbot's example is at ~3527 and you're at 3450, that's a 77lb weight difference between the E90/F80. We do know that 31lbs of that is due to the Li-ion battery in the F80. That gives 46lbs of weight reduction in the overall car, which given the significant increase in size of the F30/80 chassis and all is a great achievement in my opinion.

According to BMW Euro specs, the M3 is ~50lb heavier than the M4.

Apologies, I did not remove the floor mats or any tools. I did remove the mobility kit.

Forgot about the floor mats. Had a narrow window of time to get this done today and rushed it out the door (which is why I didn't fuel up beforehand, didn't know how long it was going to take to get it weighed)

Thanks for doing this BTW .

The good thing is that for $4, you can go back anytime with a full load of fuel .
