Not to start an argument, but my X5 diesel puts out stock 265 hp and 425 lb-ft of torque from a 3.0 liter engine. That's 88.3 hp/liter and 141.7 lb-ft/liter. This is from an engine design almost 10 years old (launched in 2008).

The Ford's 2018 numbers are from a 6.7 liter engine, so the output is 67.2 hp/liter and 139.6 lb-ft/liter.

I understand comparing an SUV to a heavy duty pick-up is not comparing apples to apples as they have a different end uses. However, BMW has to deal with the same EPA crap as Ford, so on paper an interesting comparison.

 

The BMW six diesel power is pretty much inline with the 3.0L V6 diesels currently on the market, including the RAM EcoDiesel and upcoming F150 Powerstroke. Ford engineers don’t have a ways to go, they have just produced a powerful diesel capable of pulling a massive load and managing heat.

 

If it’s built as well as it should be, it won’t make
all that much difference now will it.

 

Screw class leading power. How about class leading mileage. I don’t pull like they do in those stupid Eisenhower tunnel test. I want decent mileage unloaded and loaded.

I know I have a 450 but cruising is less than 2k rpm and I’m happy with 14 mpg. Loaded with even an empty 18’ car hauler is around 12.

Stop the power pissing match and figure out a way to make these more economical.

Agreed! I'd take 350/650 like my '08 had with a few more MPG's over the current 6.7L.

Or, better yet, give me a choice of 2 or 3 different power levels.

 

The only thing stopping huge leaps in mileage is physics...and bending the law of physics is hard. If there were massive gains in mileage to be made, they would have mostly happened by now. I'm sure there is another 10% still out there, but don't expect 30 mpg from an empty full sized truck that is also capable of hauling 6 people and a 20,000 lb trailer any time soon. Honestly, I'm pretty impressed guys are getting close to 20 in an 8000 lb truck. Over here in Europe, I'm lucky to get low 40's with my small 1.7L Ford diesel S-Max (cross between a car and squatty van) at 65 mph. When you compare the size, weight and profile of an S-Max to a SD, you'd think I should be able to get much better mileage.

I feel like the 3/4-1 ton truck mileage revolution will happen when we start adding electricity to the mix (hybrid). I believe that this will happen somewhere around 2023 given that the f150 is getting it in 2021. I honestly think that you simply can't get much better mileage while keeping decently high power and it still be reliable. You could make it smaller displacement which would get better mileage but you couldn't have high power and it be reliable and cost effective. Your not going to get better mileage out of 6.7l and keep high power.

 

I am not disagreeing with the above, but it is also a result of emission compliance. These engines run artificially inflated exhaust temperatures to run cleaner, which burns more fuel.

 

If the engine truly puts out 450/935 now, that will be a more significant gain than 10/10. The 2017 was certainly underperforming compared to its' ratings based on people complaining about it lack of power in the mountains and the fact that it got showed up on the Ike Pass test.

 

Agree 100%! Why I have kept my old 2006 Cummins and likely will even when I order a 2018 Ford F350 gasser. I will buy no diesel with EGR ever. This is a pure government slap in the face. Emissions controls suck.

 

Or 340 hp / 560 ft/lb with a decent tune and delete package...I absolutely love ours

 

Man I just don’t buy it. The emissions choke these down. If they had some sense they would run the numbers of fuel burn increase by the emissions added vs the increased efficiency which results is greater mgp.

These trucks are more aerodynamic than ever before but make the worst mileage (take out the 6.4) of HD trucks in the last 15 years. Yes we get gobs of power and pull in the mdt arena but there has to be a balance. Even those stupid 6 cylinders get much better mileage.

LOL... I've towed my 13,000 pound fifth wheel out west (from Ohio) several times. Most of them with my Ram 3500 6.7L (previous truck) and this past year with my 17 350 6.7L. The route taken this year with the Ford actually included pulling the Ike gauntlet (which made me smile) and I can tell you from first hand experience that there was no underperforming on the Ford's part. As a matter of fact, the only area that my Ram could even compare, from a powertrain perspective, is with the diesel exhaust break. The diesel exhaust break on the Ram is superior, in my opinion. Outside of that, the Ford owns it.

Drive what you like...

 

It still shows 925 torque on ford website for 2018 SuperDuty.. Wonder if they will update that.

 

The engineers will make what the marketing guys think will sell. Right now, power sells. MPG, not so much.

That may change if the fuel prices will significantly increase, or the government decides to tighten the screws on the mpg numbers.
