right on
yes it is a bit shame but they have to do something like that.
just like the Ferrari with the F40 Twin Turbo

 

Well...i suppose they had to. I dunno, it's all over me from a mechanical point of view.

Also turbo engines had alot of benefits and we know all o them (comparing 535i with 540i).

I do hope really that they will not simply destroy the M heritage also. IMO they should focus more on weight saving. Look at Ferrari, no FI engines in F430 or 599 or whatever but they have CF and alluminum body kits. BMW had only CF roof (in M cars) and some aluminum bonnet plus other stuff. But what about the chassi? Why doesn't bmw M create a full aluminum chassis or a full CF car. Answer (unfortunately): Marketing.
Also BMW needs a supercar like we need air. IMO it's odd that bmw didn't bring a supercar since M1. I hope the M10 will make it's way on the market soon and i hope they make it a proper supercar.

 

575 HP....It would be nice but I would be happy with 500 Hp and fuel range of 400 miles. Now, that would be an accomplishment!

 

ya I know itis a shame on BMW that the M is not very light or use alot of CF and alluminum on the car, even MB use alot of CF stuff.
Jag and Audi has a full alluminum car. Why not BMW
But I have to give it to them that the E60 is very light compare to other cars eg my E60 is about 40kg more than my frends E90 323i.
The M cars are becoming more and more in price so why not just make it a real sports car.

 

1- TURBOS AR EFOR HIGH RPM POWER NOT LOW RPM LIKE SUPERCHARGERS

2- ENGINE COMPRESSION WILL BE LOWERED DEPENDING ON HOW MUCH BOOST IS RAN

3- IF THEY JACK UP THE PRICE ON THIS PUPPY IM GONNA BE PISSED ! LOL

 

1 not so true. That's not a rule. Depending on the size of the turbo and of the set-up you can have a turbo spooled up almost from idle. Also there are variable turbos like Porsche VTG which makes for all the revband. Also superchargers are belt driven so in a way the higher the engine revs the higher the output. Of course the engine has to generate enoug hp from down low to actually compensate and run the blower.

 

a supercharger can only run the same revolutions as the crankshaft , a turbo can run 20, 30,000 rpm .. rpm ... thats where its power is made !
also not to mention they will need an intercooler to cool the boosted air wonder how much wieght the m5 will gain for 09 !


Superchargers = low rpm power

turbochargers = high rpm power output

 

Sorry i still don't understand your last part.

 

Superchargers= full range rpm power, but the higher the range the bigger the blower, the bigger the blower the more power consumption and heavier engine and it gets more expensive too...

Turbos= new variable types are covering a wide range of rpms, but they have a lower rpm limit and an upper rpm limit also (for example from 1800-5000rpm range for an engine that runs from 750-7000rpm), the superchargers do not have this limit .

Problems is that the Supers are more expensive to be technicaly improved than turbos, so they are less and less used.
