Re: Fuel economy Reply #1 – December 02, 2007, 10:08:06 pm Yahoo Message Number: 86668Very interesting, Jerry. Thanks!That reminds me of the hyper-miling I read about on CNN. There are techniques that people use to get more miles per gallon. Obviously, you have to be smart about it and not dangerous to folks around you. One point of interest was how they said that you really don't want to keep the engine a constant *speed* on hills, but rather, you want the engine to *work* at a constant effort. So you gradually slow going up hills and speed up going down. Also pretty amazing was the gas mileage that people were able to get from normal, gas-driven cars (not necessarily hybrids) by using various "hyper-miling" techniques.http://www.hypermiling.com/>Tessa

There's a section in the govt. report cited by Jerry that notes the significance for fuel economy of matching the size of the engine to the load, etc. Any advice from engine pros out there about whether the E450 is sized right for the 158" chassis, or is it better to "up-grade" to the V-10?

'Richard I have no idea which engine will get better mileage but I'm confused why the V-8 is even offered unless LD is trying to keep the cost down. We owned a V-8 powered 1983 LD and presently a 2003 with the V-10. All I can say is that I'm never going back. If there is the slightest possibly of pulling a toad or trailer, get the V-10. If Ford ever gets their act together and install a decent intercooled-turbo diesel, I might consider changing to another engine. As it stands, I happy with the V-10 but still occasionally dream of adding the Banks System. When pulling the Jeep, more power would be appreciated on uphills. The V-10 is certainly not overpowered. None of us will know the actual differences in mileage until a few of the V-8 models have been built and road tested over a wide variety of condition and even then, the 'results' will be questioned since only controlled testing will yield repeatable results. My feeling is the V-8 will be pushed hard more of the time and may not yield much more mileage especially in the West where hills and mountains are the normal driving conditions If mileage were your only concern, I would recommend getting a 2002 or older 23.5' model. They are built on the lighter E-350 chassis and have a 4.11 rear axle ratio compared to the E-450's 4.56 axle. From talking with owners of both and from side by side driving experiences, the E-350 gets another 1-2 MPG. The side-by-side comparisons are based upon trips with my brother who owns a 2004 24' Winnie, built on the E-350 chassis. After driving both, I still prefer the E-450 due to its superior brakes and overall feeling of strength. As usual, YMMVLarry

This is apparently not LDs choice...the V-8 appears to come standard in the 2008 E-450 chassis. You must pay extra to get the optional V-10. Why Ford has done this is anyone's guess. If I were buying a new LD right now, I'd pay the extra for the V-10 engine...not only do you get a more powerful engine, but you also get around 450# extra in GVWR (14,050# vs 14,500#).Linda Hylton http://map.datastormusers.com/user1.cfm?user=1167 http://earl-linda.blogspot.com/
