Should be a lot more pics available then.

April 25th. Tuesday.


Yes, a lot of pics. Also the Glasgow ones.
Not all the pics will be used for the press release. Some are used for internet presentations, some for catalogues, some for the next (market specific) press releases.

Lanzarote, Canary Islands.
Also the initial 645Ci press pics were taken there, as well the upcoming M6 Cabrio pics.

Scotland road was used for promo movie.

I was thinking DI was going to be used with ONLY the N54 turbo engine. I'm also thinking that the engine in the 330i will remain as it has been, just tuned up to the 1-series standard (guessing the 265 USA hp is 272 euro hp).

If that is the case. then the amount of sulfur in the fuel wouldn't matter in the uptuned N52, would it?
Also, I thought the the sulfur changes only applied to DIESEL fuels, not petrol. I think the realitvely high sulfur content of diesel fuels in America has been given as one of the reasons that we "don't get cool diesels over here".

In addition, assuming these numbers are anything close to reality, does anyone else find it curious that BMW is leaving the 325 alone and upping the 330 by 15 hp? I would think they would want to tune the 325 up to 230hp, since it is already a detuned 3.0 litre in the US.

Anyway, just some thoughts.

The Audi ones dont have the lean burn mode

BMW will be the first manufacturer outside the Japanese local market to release DI engines with a lean burn mode.
The Lean burn mode makes fuel savings of up to 20 % possible, even over the N52.

The USA fuel is supposed to be on spec by 2007, europe went on spec at the beginning of 2006

All BMW's 6 cylinder engines will go to DI

But this wont happen all at the same time, nor will it happen in all markets at the same time.

All EU member coutries fuel is supposed to conform to the required standard asof late 2005/early 2006, so BMW will start to introduce the new engines there. Possibly with the E92.


Only markets with the correct fuel will get the Lean Burn DI engines

[e90fan1234]

How much R&D goes into an engine to convert it to DI? Does it require a significant investment?

Also, what happens to Valvetronic and the like when DI is implemented?

Huge amount of R&D, they have been working on it for years.

A Number of parts of the engine need to be changed.


The cams shouldnt change much, so Valvetonic and Double VANOS will stay on the normally aspirated engines.

valvetronic isn't used anymore in the DI engines I thought/read somewhere in a German carmag.

This is bloody confusing me.

As some believe, I don't think these are really OFFICIAL photos of E92. If they are, they would be all over other big websites, such as autoweek or worldcarfans.com, which are usually first to report this kind of news.

These could be some well-crafted PS....

dunno what to think with respect to authenticity, but I have to say that I'm not a huge fan, I'm afraid. I think I like the sedan styling better...

The first statement is what I have read elsewhere in technical correspondance in car mags. (Not being able to use a lean burn mode negates many of the advantages of DI gasoline engines so most manufacturers have been reluctant to sell them in north america.) The second statement I am less sure about.

I have read that the problem with the lean burn mode is not sulphur in the fuel but the very high cylinder and exhaust temperatures which are reached with a lean mixture. These high temps cause low CO and HC in the exhaust but result in high NOX. I was told that so far the manufacturers have been able to meet European NOX emissions regs with DI gasoline engines, but not the more strict US ones. Maybe BMW has made a breakthough.

NOX causes the orange haze you see over large cities on summer evenings and when mixed with water becomes nitric acid.

These pics are official.

Leaked by two sources: Greek magazine Autotriti, and CARSCOOP.blogspot. Dutch AutoWeek also published the leaked pics on their site.

Both, the mags & the blog author, will be legally pursiuted by BMW AG. All the press that recieve press kit in advance signed (mostly chief editors or managing directors) the liability agreement with BMW AG about not breaking the embargo.

The PR is out next Tuesday, April 25th when the press embargo ends. On that day all the smart media will publish pics and all the relevant info.

[stressdoc]

How much info do you think will be released with the PR on 4/25? All colors & options? Pricing for euro market? Details of specifications?

Usually the initial PR is general PR with the highlights only, the market specific "in-detail" PRs follow later in the next months.

No experiments with this PR.

So, no colors & options (only the highlighted ones), no pricing, no detailed specs as yet.

Fleet, why doesn't the Turbo have Valvetronic?

Rumor was the DI and Valvetronic were somehow redundant, but seeing as how the Prince engines will feature both, that's obviously not the issue.

It could be possible that many of the chops we have been seeing for so long were made by BMW, and were released in order to receive responsive feedback from us. If I was incharge then that is what I would do for sure. The design we give the most positive feedback on could well be taken full steam ahead or taken back to the drawing boards to perfect.

I'm not saying that they are not PS (seriously doubt it though), but there would be a good reason for the major sites and publications not to release these pics... they are not allowed to They presumably have been given the pics by BMW and must have been given a release time and told not to release beforehand. If they disobey this then they can kiss the next official release goodbye.

I think the coupe came out looking fantastic - worlds better than the E46 coupe.

I wish we could get some definitive info on the 335i sedan for the U.S. It seems to be a definite "go" in Europe but that's all I can gather so far.

Also, I wonder how much rear space the 335i coupe will be giving up vs. the 4 door. If it's neglibigle, I might be tempted back to go back to a 2 door.
