2012 V6 Fuel Efficiency Increase
Regarding the anticipated fuel efficiency increase to be seen with the U.S. version of the new 2012 V6 engine, following is from a MB release announcing the 2012 M Class to be introduced in September.
The E350 Sedan cannot of course be directly compared to the SUV in terms of expected fuel mileage. However, the percentage increase noted in the table may well be relevant.
Unfortunately, it appears the hoped for large increase in fuel efficiency for the U.S. version of the new motor will not be realized unless/until lean-burn and start-stop technology make it here eventually.
Hope this is of interest.

Dissapointing and as expected since I checked out and posted the new CLS EPA #'s which was only a 1 mpg increase albeit with lots more power/torque so I guess we shouldn't complain.
Thanks for posting Al.

Hold on a second...Real fuel econ of new CLS V8
The new 2012 CLS EPA numbers are quite a bit better than the outgoing model.
2011 CLS550 14/21 $1300 GGT
2012 CLS550 17/26 $0 GGT
That is +3 mpg (21%) city and +5 mpg (24%) hwy.
2011 CLS63 AMG 12/18 $2600 GGT
2012 CLS63 AMG 16/25 $0 GGT
That is +4 mpg (33%) city and +7 mpg (39%) hwy.
All of this with engines of higher hp and tq. with max tq. at lower RPMs.
Of course we are talking about the new V6 but if the new V8s are any indication I like the direction things are going.
For a better indication, perhaps the new SLK350 is a good guide.
2011 SLK350 19/25 $0 GGT
2012 SLK350 20/29 $0 GGT
That is +1 mpg (5%) city and +4 mpg (16%) hwy.
Extrapolating to the E350 could mean:
2011 E350 17/24 $0 GGT
2012 E350 18/28 $0 GGT
...will be interesting to see how things turn out.

Good News
That's more like it and what I had read quite some time ago. The loss of the guzzler tax is just another benefit of the 12's.
Thanks for posting.

2011 E550, 2013 GLK
The EPA dropped the gas guzzler tax on my March 2011 build E550. Fuel economy ratings were increased to 15/23. If there is any improvement in the 2012 over my car, it's not worth it to me. I don't need the hassle of direct injection and turbo-charging nor do I want 4Matic.
Needless to say, I'm happy I was able to order a 2011 E550.
