How much fuel?

I would say the numbers certainly feel accurate... the car i drove w dct was prob 150lbs heavier given some other options... It certainly fel like it.

Thanks again

Does this really matter?

Actually, you do have a choice. Instead of using the mobile app, use the browser, and make sure to choose the "display desktop version" at the bottom if you see the mobile version of the page, and do your editing there like you do it on your PC or laptop.

I still believe the ~3,300lbs is dry weight.

The German press release use the phrase "leergewicht", which translates to empty weight, but is the word used for curb weight.

BMW has always claimed that the 3300lbs is a DIN leergewicht. Meaning all liquids and 90% fuel. This is also the weight stated in the official EU-type approval certificate.

At some point BMW has presented a M4 that weighs 3300lbs to the independent test facility (TUV)...

It probably had:

No floor mats
No nav
Manual seats
Helium filled tires
No AC?
No "options" (including "options" you can't delete from your order...)

This. Well, I suppose I should say "this-ish". If we ignore the parts that are tongue-in-cheek, I think you are on the right track. However, as I said in Joe's thread, it is still not a clear path to get down to 3300 lbs.

Powerslide, you have to keep in mind that, even with no options, the US spec M3 will have equipment that is not present on a truly base specification car in absolute terms. What are those terms? I don't know exactly, and I'm not sure if we will ever be able to get an official answer, but Boss has mentioned some things that could have potentially been omitted/substituted to get to 3300 lbs. The question of whether there is genuinely another 100 lbs. to cut is still open and unanswered. That is, even if we took the lowest spec, lowest possible weight car the EU consumer can obtain from the factory through the normal sales channels, are we still going to be over 3300 lbs? And even if we hit that number, there is the philosophical question about whether it should be fair game for BMW to use such tactics to sell the car.

That all put aside for a moment, getting back to the US where you, me, and Joe live, I think the weight numbers on bmwusa's website are reasonable. No?

You have a highly tuned sense of weight in a car I would bet professional race car drivers would be hard pressed to feel 150lbs difference in extra weight on the street.

DYI project just totally killed me. Beer and bitching ahead.

Oh no - this time getting the sedan - kids getting to big and too much carpooling for convertible now!

Oh, I can't tell the difference between 150lbs, but I can between 250... my car vs an m3 I drove.

Not necessarily disagreeing with your line of thinking, but the items you've listed aren't going to get the car to 3300# ESPECIALLY with 90% fuel.

The components that would have to be removed render the 3300# number useless.

[JoeFromPA]

Based upon my weighing an m4 with manual seats and some other deco tenting could hit 3300-3350 without much issue.

Or an m4 equipped like me but dry.

A lot of the 3300 pound argument comes from the interpretation that leergeweight meant DIN weight even though it translates as dry weight. It could have actually meant dry weight all along in which absolutely this car in US trim weighs 3300 pounds dry.

It's still a pig, slightly bigger and ever so slightly lighter than the E9x. Good thing it has the added power but I would still prefer the same power as the outgoing M3 in a smaller/lighter package, but who wouldn't....?

Him posting a comp package e9x m3 weighing 100 lb more makes this a pig? Did you consider your previous cars pigs as well?

Magic and sorcery

Did he had a cloth seats??

Wait, no manual seats? They got rid of that option in the US?

FAIL.

Does anybody have a link to where BMW claimed the F8X weighs 3,300 lbs? I see this comment a lot, but have not been able to find where BMW made this claim. As was pointed out, the weight on the BMW web site seems accurate.

Anyway, I for one don't really care if they were off on their initial claim. I'm just happy BMW shed any weight from the preceding model (a first, as we all know!).

Interesting, I was talking to a tech from Porsche yesterday and we were talking about weight. He was saying that with all of the tech being added to cars these days the total weight of the wire and electronics can exceed 1,000 lbs. I know we all want light cars but given all of the safety advances and increased reliability I am ok with weights under 3700 lbs (but prefer 3200). I was a paramedic during the 90's and early 2000's when cars were lighter and I took care of a lot of people that were severely injured in crashes that these days people walk away from (if they wear their seat belts). The data is really compelling in terms of reduction of severe injury and death, this data continues to encourage NHTSA to add more requirements (I think that is a good thing). Combine the safety advances with the performance and reliability advances and it turns out the sky is not falling after all. The fact that BMW can still reduce the weight or maintain a steady weight from between two generations is a huge achievement. I think it will be really interesting to see what happens in about 8-10 years when carbon plastics are extensively used like in the I cars. We may see pretty huge changes.

If you mean "1497kg", here it is.

The launch of the new BMW M3 Sedan and new BMW M4 Coupe sees BMW M GmbH revealing a new interpretation of the high-performance sports car – and carrying the BMW M philosophy over into the fifth generation of the M3. More than 40,000 examples of the fourth-generation BMW M3 Coupe were built, and now the BMW M4 Coupe is poised to continue this success story. The “M4” badge is a reference to the model series that provides the basis for the new M model – and, for the first time, the Coupe will be introduced at the same time as the four-door variant. Logic dictates the latter will be christened the BMW M3 Sedan.

“Four generations of the BMW M3 have blended motor sport genes and uncompromised everyday usability within an emotionally rich overall concept,” explains Dr Friedrich Nitschke, President BMW M GmbH. “The BMW M3 Sedan and BMW M4 Coupe represent an ongoing commitment to this philosophy. The engine is the heart of every M model, and the new turbocharged six-cylinder unit fitted in the two new cars combines the virtues of a high-revving naturally aspirated unit with the strengths of turbocharger technology. A committed lightweight design concept produces a weight saving of around 80 kilograms over the outgoing M3. The BMW M3 and BMW M4 take motor sport technology from the track to the road, and thousands of laps of the legendary Nürburgring Nordschleife – the world’s most exacting race track – have readied the new models for that transition. Meticulous and passion-fuelled development work has underpinned the creation of two high-performance sports cars that set new standards in terms of overall concept, precision and agility.”

The high-revving six-cylinder in-line engine with M TwinPower Turbo technology newly developed for the new BMW M3 Sedan and new BMW M4 Coupe produces a maximum output of 431 hp. Its peak torque of 550 Newton metres (406 lb-ft) is available across a wide rev band and outstrips the figure recorded by the outgoing BMW M3 by roughly 40 per cent. And yet the engine also achieves a reduction in fuel consumption and emissions of around 25 per cent. Both the BMW M3 Sedan and BMW M4 Coupe cover the sprint from 0 to 100 km/h / 62 mph in 4.1 seconds (with the optional seven-speed M Double Clutch Transmission).

In the interests of maximising dynamic ability and ensuring excellent efficiency, weight savings of around 80 kilograms have been achieved over a comparably equipped predecessor model. The BMW M4 Coupe, for example, has a DIN kerb weight of 1,497 kilograms, thanks to the rigorous application of intelligent lightweight design measures. These include the increased use of lightweight materials such as carbon-fibre-reinforced plastic (CFRP) and aluminium for a number of chassis and body components. Indeed, both models feature a carbon roof.

One of the primary objectives in the development of the BMW M3 Sedan and BMW M4 Coupe was to ensure the new cars offered impressive race track capability. Hence the presence of a track-specification cooling system, which ensures that the optimum temperature balance for the engine, turbochargers and transmission is maintained at all times.
In order to accentuate the racing character of the two models in terms of both their technical composition and the fine-tuning of the cars, the engineers worked closely with BMW Motorsport’s professional racing drivers during the development phase. For example, DTM drivers Bruno Spengler and Timo Glock took part in the extensive testing and set-up work carried out at the Nürburgring-Nordschleife circuit.

I think what you are saying is theoretically possible - US spec cars are undoubtedly going to contain more "standard" content than euro-spec cars, hence the greater weight.

Again - I'm not saying it is impossible for a 3300 lb M4. All I'm saying is if a US-spec "stripper" M3 is 3450 lbs, than a US-spec M4 stripper should, in theory, be 3,400 lbs. I would love to know how on earth even a euro spec car could shave another 100 lbs off - I just find it hard to imagine how the difference between euro spec and U.S. spec could possibly be 100 lbs... If it were 20, 30, even 50 lbs, maybe....
