No real evidence but nice info to talk about...

4Cyl Turbo : http://www.bmwblog.com/2008/04/09/rumoror-not-bmw-to-build-a-4-cylinder-twin-turbo-engine/

Both Hard and Soft Top: http://www.bmwblog.com/2008/04/10/you-heard-it-here-first-2009-bmw-z4-will-have-both-a-hard-and-a-soft-top/
 
I agree, no road car gets an 11k redline, I checked the date to see if it was April 01 it was posted on. Hmmmmm :scratchhead:
 
On another car forum we discussed the plausibility of having a tiny turbocharger for each cyclinder and whether it would work... the conclusion was that it wouldn't work very well as a single cyclnder would not have the exhaust gas volume to spool the turbo adequately... it would also be over complicated :rofl:

With the 335i twin turbo engine and new 330i efficient dynamics then I can't see why they wouldnt use these engines to power the new z cars.
 
After going through 2 sets of turbos on my old Audi S4 2.7t I am a firm believer in less complex plumbing under my hood and like having normally aspirated engines.

I am definitely not interested in another set of turblows - especially if things get more complicated yet :roll:
 
Trouble is BMW have already intimated that the next generation of performance engines from them will be bi-turbo engines. Take the latest 1 series coupe for instance. This is because of the mix of economy and emissions.
The latest eco-warrior thinking on petrol engines will mean engines getting very complicated and all gearboxes being autos!! Oh joy!! :tumbleweed:
 
I have no problem with 6 cylinder bi-turbo engines.... I've grown out of 4 cylinder turbos and wanted a better soundtrack when driving :driving:

My 3.0 inline 6 can do 30mpg in general spirited use... my Nissan 200sx (240sx to those in usa) with SR20DET @ ~280hp did 20-23mpg even after a full custom remap - was quite quick though :evil:

The efficient dynamics engines have only just come out, I should imagine they will be around for a while - there will always be a 6 cylinder in the line up, you won't see porsche ditching their boxer 6 anytime soon 8)
 
I must try harder :evil:

Lowest I have had is 25mpg when all I did was hoon around the countryside :driving:

I'm with you Alan...
The temps that the 335 runs is not meant for a long term relationship.
Just wait a couple of years & see how many of them start to fail after warranty.

Luckily mine failed within the warranty and I traded the car in with 1500 miles left on the 50000 mile warranty. Good thing too - the turbos on the 2.7t engine had to be replaced as pairs and the engine had to be dropped out to do the replacement - for $8000 worth of parts and labor.

Lots of fun to chip your turbo and get a quick 35-40hp but not worth the long term cost at all in my book.
