:unsure: Will the turbo technology from the 535d make its way into a possible 535i?

Since an engine upgrade to the 3 liter must certainly be in the making @ BMW, and the 535d engine (with much more hp than the 530d) has been announced, wouldn't the best & most cost-efficient way to a new production engine be by turbo-charging the 3.0 gasoline engine in the same way as its diesel counterpart? This would also explain all of those twin-turbo rumors that were circulating a while back.

R.R.

Doubt it,

In fact I can't recall a single BMW petro turbo engine.

as reported on the bummer, oops I mean bimmer, board.....BMW North america categorically denied any upgrading to the 530 to make it a 535i

They have had the 3.5 V8 available for some time but the gap between the 530i and 545i is not great enough to support a 535i

there will be, as we know, a 535d but it still is a 3 litre but with a twin instead of single turbo

I believe they are quoting 272 bhp and 560 Nm of torque for it !!!!!

BMW is a company whose principles are strongly based on normally aspirated engines.
power readily available through the entire range of the power bend.
their engineers and R&D excel in perfecting the hp/l output better than any other.
they make their cars faster by not only increasing engine output, but the entire package of weight, balance, suspension, wheels and new materials to name a few.
i highly doubt a gasoline engine will get turbo charged as a means to increase power. to me i would think it is a cheap easy way out. not bmw style.

Bunbun: Throughout the seventies and eighties, there were several turbocharged engines to be found under BMW bonnets. E.g. the 2002tii or the E23(?) 745i.

;) Thanks for the quick responses.
I agree with just about all points, however, rollee:

If BMW is so adamant about normally aspirated engines, why would they use a twin-turbo on their diesel model in the first place, pushing the horsepower up by such a great margin? Is that BMW's solution to selling a higher volume of the larger horsepower cars in Europe? :unsure:

I would imagine that BMW does not sell as many 545i's in Europe as they do here in the U.S. .....

Don't imagine, you're absolutely right! ;)

:huh: Great...well I guess I answered my own question, then.

(Sigh) Oh, well;; that wouldn't be the first time.... :(

We have 530 diesels rather than 545i here because petrol costs about $6/gallon!

the availability and need for the high power diesel is beneficial from an economic and geographical standpoint, due to the nature and characteristics of diesel, perhaps turbo charging is the most cost effective and efficient way to attain higher performance, unless they are willing to sacrafice 200 or so kgs to the engine?
if i live in europe my choice will be the high power diesel, it makes sense.
the development and perfection of normally aspirated gasoline engines as the trademark excellence and direction of bmw is from their top people in R&D in munich, this is also echoed by the heads of the exclusive high performance bmw m / personal division.
they want a normal looking every day car that blows others out of the water, in finesse and grace. like a perfect wife whose good all around and you know where and what. :P
BTW BMW is the blonde.

I have a BMW ETK CD (Parts CD-ROM) and in the E60 section there is a page for model emblems which includes a "535 i". There is no part number for it yet, but the picture is there. If you look at the bottom of the page you can see that I selected the E60 5 series, so this page is not from any of the previous 5 series section. I am NOT saying that BMW will definately be making an E60 535 i in the future, but just making an observation that the emblem is shown on their parts CD. You decide.....Here's that page from the ETK CD:

I see what you mean but conversely there is no 535d badge and we know that is a confirmed model. guess we will need to wait and see.

thanks for the info

I think BMW might come out with 2.5 and 3l valvetronic engines in 2006.

During the launch of the E60 in Singapore, I spoke to a German guy from BMW Asia and he said the 6cylinder valvetronic engines are due in about 2 years.

Since Volkswagon has a new 3.2 V6 with more power and torque than the M54, BMW might answer by increasing the capacity a little and boost power

Power sells but its torque that makes BMW's so good as "real world driving" shows.

Thats why the 3litre diesel is so popular here

BMW UK state that 43% of all E60s sold are 530d models....thats why they are delaying the 3.0d in the X3....demand for the engine which features in the 3 saloon, coupe and touring, the 5 saloon and touring, the X5 and even the 7 is just too great and they are looking at expanding engine production to cope.

I wish the Singapore goverment would allow private vehicles to use diesel engines. A 535d would be awesome, In fact, I would luv a Tourag V10...

Unfortunately, it's unlikely to happend anytime soon.... :(

I don't know why they don't,, a Euro4 complient engine like the latest BMW diesel 2.5 and 3 litre pollute a whole lot less than the gasoline equivalent, I even got straight tailpipes on mine as it has a particulate filter.

Ahhh..I see! I think you posted this info a while back on bimmer.org. Very interesting.....

But Doctor Diesel makes a good point about the 535d...where is that model designation? And where on God's green Earth is a 518i available????? I guess we'll just have to wait & see.

ALSO, I am wondering if anyone on this board attended the BMWNA Car Club meeting on Friday, June 11th. Sometimes they give out little snippets of info for the upcoming model year.....which would include the new 3 Series.

518i was available upto (not including) the E39 model....it was an absolute dog, and an extremely slow one at that!!!
