Consumer Reports declares the Ford F-250 Lariat 2010's worst gas (diesel) guzzler

It was an underpowered turd

 

I find that hard to believe.

SCR allows increases MPGs by reducing the need to control NOX emissions, thus the combustion temperatures can be increase. However it does not look like ford went this route. They dropped the compression ratio even further, and two massive EGR coolers now consume the engine compartment. Not to mention the increased power/tq which is at 390hp and 735lb-ft.

Not to mention Fords are heavy, 7,000lb must have been a smaller Ford.

On the HD pickup diesel note, GM released their numbers for the LML Duramax 6.6L at 397hp and 765lb-ft of torque.

And then theres Dodge who is still sitting back at 350hp and 650lb-ft. They must be relying on the Cummins name as always.

I wonder when the power wars will end between the big 3.

 

Wayne does a lot of things that are hard to believe for most people. He has a review blog at 2011 Ford Super Duty Press Launch - CleanMPG Forums if you want to ask him any questions.

High compression is theoretically more efficient, but there's a few reasons why manufacturers aren't running as high of compression as they used to. Emissions and NVH are two of the big ones. Honda found with their i-CTDi that the relatively low compression ratio actually helped efficiency in lower load situations.

I saw some of the info on the new Duramax the other day. I was somewhat disappointed with the 5k miles urea refill and oil change interval. Ford allows 7.5k miles with their engine and SCR system, and it can also run B20 and uses post injection for DPF regeneration. I would have liked to see a bigger DEF tank and longer OCI with the new Duramax.

 

That would tend to increase long term costs, especially when you consider how much oil those things hold

 

I haven't seen the new oil change interval ratings. It was always 10,000 but could be leass now, but there's still tons of people who live by 3,000 mile oil changes for some reason.

IIRC the duramax now has post turbo Injection for the DPF but again I'm really not up to par on the new Duramax yet because nobody knows when it will come out. They are on government time.

 

I thought the EPA required DEF intervals to be at least as long as the OCI, so it was mostly an assumption on my part. That's still annoying to have to top up the DEF twice as frequently as the shortest service interval if the OCI is really 10k miles. BMW has a 5 gallon DEF tank on their 335d. It's hard to believe GM could only find room for a 5.5 gallon tank on their HD trucks.

 

The EPA does set the minimum standards. On OTR trucks its by how much fuel they hold. Im sure passenger vehicles are different and go by the oil change interval.

OTR trucks are by the fuel capacity due to the fact that Truck stops are installing DEF pumps. The biggest DEF tank on an OTR truck is still less than 20 gallons.

Now as for GMs 5.5 gallon tank. Im sure there are many political reasons why it is that way. If the tank is smaller that means most folks will have to come back to the dealer more often. and while the truck is there getting its DEF the dealer can say that this and that is wrong with it and just keep racking up the charges. This is America as we know it. Most people dont know much about their cars and take the dealers word like its gold.

 

This is also Canada as we know it.

Very sad how brainless people have become
