mt says 4.4ltrs.

[hector]

in march mt they state 4.4ltrs. with 425 horses echoing statements by road and track a month or two ago. could 4.4 be correct as opposed to 4.0?

I don´t think that the new M3 engine has more than 4.0 ltr., there are some reason:

1. because with 425hp that meens that the new engine has fewer than 100hp / ltr., that was lower than every M BMW from the past till now and also lower than the new Audi RS4...and BMW is much more experienced in the prodution of high-performence engines without turbo.

2. Mr.Richter from the BMW M-GmbH stated that 0.5 ltr. is the perfect displacement for every cylinder, that meens V8 = 4.0 or V10 = 5.0.

3. The new M3 - V8 engine was developed from the M5 - V10 engine with two cylinders cut off...that meens also that the new engine comes with 4.0 ltr.

I think the 4.4 ltr. thread comes originaly from the german car-newspaper "AutoBild" in which the journalist Georg Kacher stated in August 2005 that the new engine was an 4.4 ltr. with 425hp.
I beleave the new M3 engine becomes an 4.0 ltr. with horsepower in the range between 414 and 434.

You know what, I don't buy it either. BMW plays with their nomenclature so much these days (*ahem 550i is actually a 4.8L, wtf*) but really they don't do much with their liter-age. Obviously BMW know how to make a powerful engine thats efficient at the same time and dont have to go the benz route of just making the engines bigger and bigger in displacement. So my money is that BMW goes with the tried and true 4.0L size and would just play with different materials in engine construction in order to let the thing rev to a higher threshold, which is more of the type of car the M3 has become (more of a highstrung car rather then a big block cruiser).

lols good call, probably woulda been a good move ta call it the 4. but hey thats old news, its definitly called a 335i. not even a "Ci", just plain old "i" like the sedan.

They've been doing that for decades.

According to the dealer i have placed the order with BMW have confirmed to their staff that it will be a 4 litre

But hey,what the f**k do i know

4.0
M3 will be BMW's entry for GT3 category (beware GT3!). 4.0L engine capacity seems to be the best compromise.
///M is no AMG.
