: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.
