Don't get too hung up on the torque of a diesel engine. Remember that the torque is produced over a very narrow rev range compared to a petrol engine. Therefore, for the road speed it needs to cover, the gearing has to be very tall, again compared to a petrol engine thus reducing the 'multiplier' effect.
By way of example a UK 330d (three litre diesel ) produces in excess of 400lb/ft of torque, yet it's flat out performance is nearly identical to a 328i with 258lb/ft of torque.

[Apl440i or 335d?]

Nice choice of car. The 2.0d engine is a real peach.

You US guys would love the 335d though.

I have just gone from a 320d (328d to you) to a 335d.

313 hp
630nm
0-60 in 4.6s
40+ mpg

And the way it goes from 70mph to 120mph (on a track) is amazing!

In the US there is certainly room for both engines but alas we have one. I would most certainly sign up of the 313hp engine not the 265hp they had here before.

How is the efficiency (in %) relative to the 320d (us spec 328d).

[Apl440i or 335d?]

I would easily get 50mpg from the 320d and around 40mpg from the 335d. So around 20% worse?

Wow, this is why we need both engines here. Unless you like manual rwd cars I see no point in not getting the 335d. Both engines make the strongest case for "efficient dynamics"

As even the 5 series didn't get this one it's highly unlikely that it will come here. It would likely be my 1st option for a daily driver 3 or 5 series.

But why do they call it the 328 in U.S.? This just seems stupid to me. Its not as if you can put it against the 328i because that has 245 hp...

Here we go again. They call it 328 because that's the trim level for this car.

Marketing. The 320i (180 hp btw) is also sold in the US but it's $3k less than the 320d (328d US). BMW had to price it with the 328i.

Hmm, not sure thats the reason. Its normal for a diesel engine to cost more than the equivalent petrol engine. Its because it costs them more in production, especially in making it meet the emission standards. Even though a diesel engine consumes less fuel and has lower co2 emissions per km they are a lot more polluting than petrol engines. (Whitch is why its so weird that diesel is so much promoted over here in eu...but thats politics I guess..)

Thanks for your kind reply. Ahum
I think its indeed more like other people have said, for marketing reasons, and they probably adjusted the trim level to the name they gave it.

[Handyman2007]

Congrats on the new 328d, I also bought one in Nov 2013 and now with about 4,000km on it, which I took very easy, I now enjoy it. Just returning from a trip from Ottawa, ON to Quebec City, QC which was 450km away and when I got there I still had 450km left in the tank I was quite impress as the weather was -25 Celius and the engine never got fully warmed up. I bought the Sport Line version here in Canada as it is the most sporty version you can buy

[Grocery_Getter]

I've had my car for three months now and with about 5000 miles on it, and it's been great. However I've recently found a check engine light due to the blue additive spray unit not responding for emissions control.

[snowghost]

I rented a 6MT 320d in Munich and it was a fun car to drive. IIRC the 328d here is only available in Auto--deal breaker for me.

You are totally wrong that the diesel is "more polluting" than the petrol engine. See post #5 in this thread: http://www.bimmerfest.com/forums/sho...265&highlight= I think the whole thread would be enlightening for you.

It's "politics" that makes you think that way about clean diesel.

Please, I've read the thread on the other forum and it most certainly did not enlighten me.
I feel sorry for you that you base all your "facts" on 1 post from a guy who references to some hard to understand pdf files and on which I could'nt make out the values he posted. I wonder if you've even taken the effort to look at those pdf files and if you could read/understand them.. Because I could'nt.

This is not a discussion between "your" opinion and "mine". It is just a fact that diesel is more polluting than petrol and everyone who knows something about this matter knows this.

To help back up this fact I have some "enlightening lecture" for you:

http://www.air-quality.org.uk/26.php
This article states among other things that

Diesel fuel contains no lead and emissions of the regulated pollutants (carbon monoxide, hydrocarbons and nitrogen oxides) are lower than those from petrol cars without a catalyst. However, when compared to petrol cars with a catalyst, diesels have higher emissions of NOx and much higher emissions of particulate matter

http://www.acea.be/news/news_detail/...el_and_petrol/

Note: 1kg of diesel burnt under ideal conditions will produce 2.65kg of CO2. 1kg of petrol burnt under ideal conditions will produce 2.3kg of CO2

http://www.theguardian.com/uk/2013/j...s-worse-petrol

A 2011 test by government to measure emissions from vehicles in everyday use concluded that, while petrol emissions had improved by 96%, "emissions of NOx [nitrogen oxide from diesel cars and light goods vehicles] have not decreased for the past 15-20 years".

I can go on and on providing you with more articles and evidence, but you probably get what I mean and where I get the idea from.
That last article from The Guardian covers what I meanth concerning the politics in Europe that have promoted diesel for so many years, not just in UK but other countries too.

[Math]

To the OP, sorry for the thread jack..

You're putting wxmanCCM down because you don't know 0.001% of what he knows?!? Please. He happens to be a professional who has worked in the field of emissions monitoring and air quality for 30 years. I have been reading his posts for the past ten years on tdi.club and elsewhere on the web. Believe me, he can understand tables like that because he creates them for a living. He listed them to show the hard data behind what he said, just as any scientist would. The fact that you insult what you can't understand says a lot.

It is just a fact that diesel is more polluting than petrol and everyone who knows something about this matter knows this.

Unfortunately, you are not one of those people.

This report is now largely irrelevant concerning diesels; it was published in the late 1990s before clean diesel technology had been introduced to the marketplace. It makes no mention of clean diesel technology that I can see.

Note: 1kg of diesel burnt under ideal conditions will produce 2.65kg of CO2. 1kg of petrol burnt under ideal conditions will produce 2.3kg of CO2

This is a 15% difference in raw numbers that does not take into account auto emissions technologies. It is also misleading since diesel is 30% more efficient as a fuel, so the net result is that diesel releases a lot less CO2 into the air per mile traveled.

http://www.theguardian.com/uk/2013/j...s-worse-petrol
"A 2011 test by government to measure emissions from vehicles in everyday use concluded that, while petrol emissions had improved by 96%, "emissions of NOx [nitrogen oxide from diesel cars and light goods vehicles] have not decreased for the past 15-20 years".

This is misleading for a number of reasons. They are speaking of aggregate emissions which are primarily due to aging "dirty diesel" buses, trucks, and taxis in urban traffic. As vehicles age and and not well-maintained, emissions get worse.

I have reams of technical data to support that conclusion.

I know that the EU is directing its attention to diesel emissions (NOx in particular - http://www.theguardian.com/uk/2013/j...s-worse-petrol) but it appears more of a case of trying to justify higher taxes on diesel vehicles/fuel. Unless these European cities are having a problem with high ambient NO2 levels (NO2 is a component of NOx), the AQ problem is more likely to be caused by NMOG emissions from petrol (see http://www.greencarcongress.com/2013...-20130419.html). NOx emissions are being addressed with Euro 6 anyway.

The UK is well-known to have lax regulations regarding diesel emissions compared to the rest of Europe and to the U.S., and enforcement even those poor regulations is poor. Britain does not use the ULSD that we do. Aggregate numbers like those used in The Guardian article might be accurate in the UK but are irrelevant here. You certainly can't make general judgments about the nature of clean diesel emissions based on local conditions in English cities.

Diesel Truck and Buses Have Reduced NOx Emissions by 99% And Particulate Emissions by 98%

“A complete transformation of diesel technology in the U.S. has taken place in the last decade that has virtually eliminated particulate (soot) emissions from new diesel engines across the board. For example, emissions from heavy-duty diesel trucks and buses have been reduced by 99 percent for nitrogen oxides (NOx) - an ozone precursor - and 98 percent for particulate emissions, which include black carbon. Today, clean diesel technology with near zero emissions is standard equipment in nearly all off-road diesel vehicles and equipment such as construction equipment, agricultural vehicles, stationary generators, locomotives and marine vehicles.

“Thanks to the switch to ultra-low sulfur diesel fuel coupled with advances in diesel engine design and emissions control technology, fine particulate emissions have been virtually eliminated from new diesel vehicles and equipment in the U.S.

“Today diesel engines are responsible for less than six percent of all particulate emissions in the U.S.,” Schaeffer said.

And these numbers will continue to improve radically:

Hate when threads get taken over by some other nonsense that the OP never talked about. This thread was about being impressed by 328d and should have stayed that way. So annoying when it gets off track!!!!! You get excited to read another post about the 328d and instead read about some other topic!!!

Congrats on the new car ...love the diesel option.

That's my fault, mea culpa. I couldn't resist responding to someone wrongly dissing the car this fellow bought and loves. I'll keep my trap shut about that from now on.

Its okay. I love the information being presented here. Very informative.

I wasn't dissing his car at all. As you might have noticed I drive a (smaller engined) diesel car myself, have driven diesel for the past 10 years and love it for daily driving. In fact my next car will hopefully have the exact same engine as the OP as I would love a 220d next..
I'm just not convinced it's as clean/eco/health-friendly as most believe, thats all. We've both stated our opinions, and I agree we should leave it at this.
