Im pretty sure its the N47. As far as i know all the 3.0 dD's from now forward are the N57.

...The 8 speed transmission and .26 drag coefficient (compared to our .29) make for 48mpg. Not bad at all!

Over the years I have read uncountable press releases and promises of cars to built that get xxxmpg and every time they come to be submitted to the EPA for mileage testing, the manufacturers are humbled when the Feds slap the rating stickers in the windows. I will believe 48 mpg when I see it. The most fuel efficient D-Powered car sold in America today is the Passat TDI manual that weighs 3300 lbs and has 140 hp and is rated at 43 mpg highway.
A 3 Series 335D weighs in at 3800+ pounds. The new 3 Series D is not going to weigh in at no Passat weight and it is going to need more than 8 gears and a .26 drag ratio to get 48mpg. I hope I am wrong, but I think not.

I've gotten ~48MPG (full to empty) on my 335 multiple times. I could give a crap what the EPA says.

I don't know about 48 (unless on a perfectly smooth road, no stops and going about 50 MPH), but for 300+ miles trips I can reliably break 40 mpg under the correct conditions. Highway, less than 75 MPH, no traffic, and about 60 degrees (no AC, windows closed). My wife has acheived this as well when driving (she made our all time high of 42). We have been thrilled with the 335D and with 30K miles, have yet to see a SES (fingers crossed). Only been back to the dealer for routine and recalls.

I'm a bit disspointed in the next generation diesels in the 3 series. While the 335D was over powered, I think given the weight of modern BMW's 180 HP is underpowered. I expect any BMW to do near a 6 second 0-60. Agree that getting into the 5's is unecessary for most.

We have a 540iT to replace at some point (rarest car BMW ever imported), and the 3 GT is looking pretty good, but not with 180 hp, regardless of the MPG.

Diesels and hybrids don't really fit the original EPA fuel economy test cycle. The original cycle was something domestic manufacturers could design their cars to, while imports especially from European manufacturers, did not have this test in mind in their original designs.

The EPA has tried to modify their testing a bit, but around 2007 downgraded their numbers across the board. This was especially unfair to diesels which had numbers that were already too low to begin with. Hence the many journalists and bloggers that compare to a gasser "equivalent" and only look at EPA numbers, displacement, and number of cylinders, just don't get it.

Certainly BMW drivers may be the exception since the cars themselves encourage more spirited driving. But the continued avoidance of this issue and apparent bias against diesels in other ways doesn't give us much faith in EPA numbers.

Im with Ron1n damn the EPA, it can be achieved 46 mpg I did it here in Puerto Rico Only for a short term but was kept between 40-46 mpg at 70 mph w a/c on mind we are small island here and at least 4 million cars!!!

Thx for sharing!
Great wife car!

The EPA numbers are not meant to predict the actual mileage you'll get-- but rather a way to get an apples-to-apples comparison between cars.

Meaning if you get 46mpg out of a 335d, you'd also far exceed the EPA ratings in just about any other car given the same driving conditions.

I'm averaging 24-25mpg now with my 10-mile (60-70% city) commute.

The objections to the EPA is usually that diesels get better than the numbers suggest while gassers, including hybrids, usually get worse. This makes pundits who use EPA numbers comparing "apples to apples" generally inaccurate in their views of diesels. Not always, but in my experience, this usually happen almost exclusively due to EPA numbers.

I must have got a lemon as the best I can hope for is maybe 40(never done it) under ideal circumstances ie no wind, flat terrain and 65. As it is, I get 34-36 at 75 down I-5 to Disneyland.

All this talk about the 328D getting 48 mpg is just hype from a European manufacturer that most likely does not understand the convoluted ways our EPA does their testing. If VW with a 3300 pound car and 140 hp can only muster a 43mpg rating, then I find it hard to imagine a 3800 pound BMW with 180 hp will hit 48 when the sticker hits the window. When the dust settles, I bet the 328D ratings will be 26/38. Not bad mind you, but not a significant jump over the 335D rating.

I have 2012 Passat TDI SE 6-manual and I drive a 90 mile commute 5 to 6 days a week and I have averaged 46.4 mpg since day 1(odometer now 21,000+), but I have to drive 66 mph to get it.

Our 335D has barely 15,000 on the odometer and the my GF drives it mostly. Unfortunately, her drives are short and she has this innate abilty to bring out the worst mileage in any vehicle she drives. She managed a 22 mpg tank by driving these short trips to and from her office. I get to drive it on the weekend and drive like I stole it.

[Pierre Louis]

2011 335d:
EPA: 27
Fuelly: 30.6

2011 335i:
EPA: 22
Fuelly: 21.8

2012 Jetta TDI:
EPA: 34
Fuelly: 38.3

2012 Prius:
EPA: 50
Fuelly: 48.0

While there are many more details worth comparing, the person that looks at EPA figures might think the gasser version of the 335i is only 5 mpg worse when its more like 9 mpg. Comparing a Jetta TDi with a Prius one might think there is a whopping 16 mpg difference when its really about 10 mpg. On the highway, diesels would be even better than that, as shown in several comparisons of past Prii and Jettae!

Many times I've thought about engineering access via trunk floor.

[Puerto Rican 335d]

Remember guys i have the WAGNER IC thats one of the reasons I can achieve on short burst up to 40-46 mpg If I lived in Florida it can be achieved just ask TurboEddie from anothe site he was the first 335d that I am aware of on all of the forums here stateside that installed an IC from Cx Racing from a 335i and modded it to fit the "D".

The new 3 weighs less than the 335d. The 328d will hit 43+ easily.

Exactly. I think some of us are just fine with our 500+ lbs. (thanks to JBD) of mind-numbing torque. Plus, I still haven't gotten used to the looks of the F30. That front...
