Replying to: markcincinnati (Jan 07, 2007 1:14 pm) Oh I'm sure it will. Now that they pretty much all have electric steering, the "next big thing" seems to be variable ratio. That is except for Infiniti, who seem to be more interested in steering with the rear wheels. Nissan has been playing around with that for a very long time. |

"A 535xi with a sport suspension ought to be a fantastic car, perhaps an even better choice with THAT engine than the current V8's BMW offers" - markcincinnati BMW's press kit ( yesterday ) confirms the 535i & 535xi. The "Updated Styling" ( in the few pictures I have seen ) does not make the 5 any more arttractive to MY eyes, but YMMV. - Ray Looking forward to test driving the RWD version . . .

You know, this whole breathed on I6 engine thing has got me to wondering. Would it be possible to transplant one of the new mills from the 335i/535i into a late E39 5-Series? Geez, what I wouldn't give to have my old 2002 530i with that mill stuffed under the hood.  Best Regards, Shipo

Replying to: lexusguy (Jan 10, 2007 7:22 am) 1) The engine in the 2002 E39 was the previous style (and in fact many years old in its life cycle) aluminum block with the cast iron sleeves. Decent for its purpose, but hardly as robust as the new aluminum core/magnesium shell composite block that debuted with the introduction of the E90. 2) Factory built turbocharged engines are typically reinforced (over that of the normally aspirated siblings) with the following goodies: - 2a) Higher strength crank, rods and pistons - 2b) Rod based oil squirters to cool the piston domes - 2c) Considerably greater cooling capabilities such as: - - 2cA) Larger radiator and the necessary plumbing - - 2cB) Additional and/or larger oil coolers and the necessary plumbing - - 2cC) Large size intercooler(s) and the necessary plumbing - - 2cD) Extra coolant plumbing to the bearings on the turbine houseing to keep them cool, especially at shutdown - 2d) Significant software remapping - 2e) Revised/more robust valve train - 2f) Higher flow intake and exhaust manifolds (2 in the case of the 335i) Did BMW do all of the above to the 335i engine? Probably. Would I trust the (bored out to within an inch of its life) 3.0 liter mill from an E39 to withstand the rigors of a 300 (320-340 by all accounts) HP turbocharging application? Not a chance. While the old 3.0 liter mill was certainly a good and robust engine for its intended output, there is only one word to describe what would happen to that engine when an intake charge 150% of design spec was fed into it. KABOOM! Best Regards, Shipo

Replying to: rayainsw (Jan 10, 2007 6:16 am) After reading your post, I went to the BMW USA web site under Future Vehicles and read the overview and press release on the new 5 series. Does the press kit you mentioned have any additional information than the web site? In the overview, when describing the 550i sport package, they say " ... new 19” double spoke alloy wheels (non run-flat) ... " Does anyone know if this implies that versions other than the 550i SP will have RFTs? Thanks Bruce

Replying to: bruceomega (Jan 10, 2007 12:07 pm) So far, I have only seen a batch of additional photographs - that I do not yet see on the web site. - Ray Semi-happy with my run-flats.... |
