Below are the complete specifications for the sixth generation BMW 3 series sedan, chassis code F30. The F30 328i and 335i, which will be the two main 3 series sold in the US are stacked up against the out going fifth generation 3 series sedan, chassis code E90 and the forth generation 3 series sedan, chassis code E46. This gives you a good idea how much the 3 series has changed over the last 14 years.

See the Official 2012 BMW 3 Series World Premier Thread for more details.

Yeah, the new 3 series has certainly changed pretty drastically over the years. Just looking at the measurements, it is crazy to see how much bigger the car is than it was just a couple generations ago.

The one positive may be that at least the F30 dropped some weight from the E90....

Holy cow that sucker has gotten big. And it's lighter than the E90?? That's some engineering right there!

It is pretty amazing the gas mileage they are coaxing out of these cars....while keeping up with the horsepower / torque numbers we have all come to expect. My only complaint is the size but there isn't much we can do about that I guess.

This has got to make the F30 as big as the E39 5-Series, surely? It's whole a size up (at least when I was last buying a new car).

Looks like the next 1-Series (damn you front-wheel drive!) will be like a three-generation-ago 3-Series.

Why has it gotten so big?! I'll bet it's a big as the E39.

It has to be close in size to the E39. I'll try to find some specs for the E39 and post them.

The new F20 1 series is not front wheel drive - http://www.bimmerfest.com/forums/showthread.php?t=546631

Yeah, I know the newly released 1-Series is still RWD, but the third generation 1-Series is supposed to be based on the ever expanding Mini FWD platform.

I wonder if BMW has a policy of going 'one size up' every three model releases?

I know there has been rumor about the next 1er getting FWD but their strategy is always changing too. I really can't see them not having a small, sporty and compact RWD car to attract entry level enthusiasts. Maybe the 1er will get split up into FWD models and RWD models??

I'll be the first to admit...stranger things have happened though.

Size is one thing. I'm not so against the increase in size since there is the 1 series to choose from if you want something smaller. And a nice set of coilovers will fix that height. I'm just glad they are lighter.

I am wishing there was a 1-Series sedan. Just test drove a E90 manual to replace my aged E46 auto. The E90 is such a step up in refinement from the E46. I dare not drive the F30 for fear of dissing my future E90.

Why is it so friggen big? This car is way too similar to the F10 5.

I've been reviewing the 0-100km/h and 0-60mph times from the BMW Press release and the BMW USA dealers sheet and BMW has something wrong with their standing start acceleration times for the F30 2012 BMW 3 series sedan -

From International BMW F30 press kit -
the new BMW 335i can show off its prowess with a 0 to 100 km/h (62 mph) sprint time of just 5.5 seconds, which shaves 0.1 seconds off that of its equally powerful predecessor. The automatic version is even quicker, reaching 100 km/h (62 mph) a full 0.3 seconds faster than the outgoing model.
From USA F30 dealer info kit -
The initial 0-60mph time for the 335i is 5.4 seconds with the manual transmission (same as the outgoing model) and the automatic transmission (-0.2 sec versus outgoing model).
0-60 mph speed
  • E90 328i sedan - 6.3 manual / 6.9 auto
  • E90 335i sedan - 5.4 manual / 5.6 auto
  • F30 328i sedan - 5.7 manual / 5.9 auto
  • F30 335i sedan - 5.4 manual / 5.4 auto
0-100 km/h (0-62mph) speed
  • E90 328i sedan - 6.7 manual
  • E90 335i sedan - 5.6 manual
  • F30 328i sedan - 5.9 manual and auto
  • F30 335i sedan - 5.5 manual / 5.3 auto
So according to BMW Germany the 335i auto can go faster 0-62 then what BMW USA says the 335i auto can get from 0-60 in. Anyone else find this a bit questionable?

BMW has been extremely vocal in talking about the impressive fuel economy of the 328 and 335 models. I fully expect these numbers to come in around what they have said...I am still quite impressed whenever we take the 335i on longer trips. You can get awesome gas mileage out of the N54 cruising at high speed. I love it.
