Well, it finally looks like it's going to happen, BMW is finally bringing some of their wonderful diesel engined cars to the U.S.A. (the 335d being one of the first). Personally, I can't wait.

I think I mentioned that I drove a 535d last fall. It's a great engine- it almost made me forgive the looks of the E60...
I'm looking forward to testing the 335d.

Yeah, I think I remember you saying something to that effect.
 
Now, five model years into the E60, I'm still not at all sold on its looks, and even a 3.5 liter diesel under the hood can only dull the looks so much.

The 335d offers 328i performance at a 5-series price. All to get an extra 2 MPG?
 
Plus the 328i weighs less and has a much higher rev limit (sportier and more fun to drive). I don't get it - am I missing something?

I'm not sure where you're getting your figures from, however, I expect the 335d to price out at a very similar price to the 335i. I also expect the 335d to easily out perform a 328i between say 20 and 120 mph, all while getting some eight to ten more miles out of each gallon of fuel.
 
Needless to say it's all mere speculation until the rubber actually hits the pavement here in the States.

I'm in agreement with you. I would expect at least 40 mpg on the highway. Idling in traffic a diesel sips fuel compared to a gas engine. I read some article at some point on gas vs diesel, and while I don't exactly remember the numbers, I seem to recall a gas engine idling for an hour uses a gallon of gas, a diesel will use 1/4 gallon.
 
I would also expect the diesel to be heavier due to added weight of engine and associated components and additional pollution "stuff".
 
Now hopefully it will come in an xi version. :tongue

Regarding the idling process. Gasoline engines run "rich", especially at idle, and that means an air/fuel ratio of about 14,0:1. Modern diesel engines on the other hand run "lean", no, as you were. Modern diesel engines run very "lean". I came across a paper in the S.A.E. archives a few weeks ago that was discussing this very aspect of Dr. Diesel's latest incarnation, and was delighted to learn that traditionally, diesel engines would idle with an air/fuel ratio of about 60:1, however, recent injector advances have been able to make that ratio seem positively wasteful as new engines typically idle at 100:1! Yikes, talk about lean. Yeesh.

I went to the BMW UK website and got specs for the 335d and compared them to specs for the 325i and 330i (I split the difference between them for acceleration and MPG).
 
325i SE/330i SE - 39.8/39.2 MPG (imperial); 0-62 in 6.7/6.1 secs
Average (328i) - 39.5 MPG (32.9 MPG US); 0-62 in 6.4 secs
 
335d SE - 42.2 MPG (35.1 MPG US); 0-62 in 6.2 secs
 
335d SE - £33,610
335i SE - £31,550
 
So according to the BMW UK website, compared to the 328i, the 335d is 0.2 seconds quicker to 62 MPH and gets 2.2 MPG better economy. The 335d is also £2,000 more expensive than the 335i. Oh yeah, the 335d weighs 300 lbs more than the 328i.
 
Sure, the low-end torque and mid-range grunt is a plus, but it's at the expense of a free-revving, high RPM gas engine that, in my opinion, is what makes a BMW so much fun to drive.
 
Unless my facts are wrong (and I admit we don't know how much it will cost here), it looks like the 335d is an overweight, overpriced pig.

Car and Driver tested a 330d and knocked off a six second 0-60 time. They predict that the 335d will do 0-60 in the mid-fives. Also remember that there are 428 pound-feet of torque available from 1750 to 2250 rpm. And I'll bet most folks will average 30-35 mpg overall. While the new diesels aren't the high rpm thoroughbreds you and I prefer, I think an oil burner may just find its way into my garage.

Sorry, the numbers I got off the UK website say otherwise.
 
And for an apples to apples reference, this from the BMW UK website:
 
330d SE - £30,285; 46.3 MPG (38.5 MPG US); 0-62 MPH in 6.7 secs
