Questions on gas mileage and newer diesel by mandochop

Hi all,
 
The R class looks good for our family for a number of reasons. I have two questions about fuel economy and fuel type.
 
First, any guesses on the fuel economy of the gasoline models coming out this fall? While poking around on some UK sites it seems as if the V6 might get close to 30 mpg. Any ideas /guesses on this? What about the V8? (and PS, what does cdi mean?)
 
Second, I've read the few posts here about diesel. Don't know much about that. So there is a new low sulphur diesel fuel that will be available? Will it be available here in the states? Any guesses if an R series diesel will be with this new diesel fuel or the current stuff?
 
Well, it's probably clear that I don't know much about these sorts of things. ve found no definitive info from MBZ, so I'd guess that responses are probably conjecture. Please let me know how / why you have the opinion and info that you do on these questions.
 
Thanks in advance!

Welcome to the forum. MB has put out a little on the engines they will offer for the "R" class vehicles. What I read was first we get the gas versions 350 & 500 same as the ML. Next and in conjunction with the mandate on ULSD for the entire USA, they will add the 320 V6 CDI (diesel) & a possible diesel/hybrid. I would be surprised if the diesel R shows up before the first part of 2007. That is what I am holding out for. Here is some info on that diesel engine and what it is capable of.

Common-rail Direct Injection (CDI) That is Mercedes newest diesel technology.

Thanks for the info and the link to the article about the diesel engine... very impressive to say the least, I can see why you might hold out for it. Actually, makes me think that might be the right thing for us to do, too...
 
Can anyone tell me the mileage for the two M Class engines? I'd appreciate that, too.

A visit to your local MB dealer to test drive the new M-class will tell you more than half of what you might be wondering as far as Drivability, fit and finish, acceleration and braking. You can probably expect 3-5 miles better per gallon in the R vs. the M, realistically. Premium fuel.
