So what do you think the future will hold for the 6.7? Do you think Ford will continue with it and just make tweaks every year or do you think they will come out with a whole new diesel engine? I'm sure EPA will play a huge role in that but how much longer do you think Ford will run with the 6.7 till a bigger or smaller engine comes out?

 

I think it will be around at least till the epa forces a change. Absent anything currently in the works, it should be around at least another 3 years.

 

Hopefully for another 7

 

The 6.7 will be replaced with an eco-boost engine. Its a no brainer now. 1200lb tq and 500hp would be easy from a 6 or 7 litre ecoboost and would not have the maint headaches of a diesel. I would buy one.

 

Yea, I don't see that happening cause that engine wouldn't last 50k miles when towing 20-30k pounds.

 

More than likely a diesel electric hybrid will replace the big V8

 

I don't see the diesel option going away either.

 

Which would be equivalent to a 12 or 14 L naturally aspirated engine and couldn't pass a gas station nor would it support the CAFE goals.


I see the 6.7PSD being around for many years receiving updates as new technology is available. Supposedly some diesels will eliminate the EGR and have all the emissions downstream in the exhaust.

 

It isn't going away anytime soon. This motor over a has been fantastic and really hasn't needed to change much over its 7 years. I know it easily runs over 500/1000as they've been running it for 2 years. They have plenty of room to keep upping power to stay competitive. The next epa phase is 2022 or 2025?

look at the dramax since what, 2001?

 

With DEF about to be "banned" on new builds for cars/trucks in California, I assume there will be some changes.

 

The Dmax is a totally different engine than 2001 version. Hell its totally different than last years Dmax.

 

I think the 6.7 is going to continue for several more years until the EPA finally forces a change. The engine still has a lot of power left in it so it can stay competitive. Eventually the next step I think will be adding a hybrid system much like Ford is doing to the f150 in the early 2020's. Even when they add the hybrid, I think they will continue to use a large v8 turbo diesel. Think about it: electric= less fuel burned= better fuel economy and less emissions= fewer regens= more reliable longer lasting motor. It also can add torque in the small gap when the turbo is spoiling up as well as add horsepower as diesels struggle with that.

Diesel will for sure remain the top engine as well as it being a v8.

 

7 litre gasoline turbo motor?
Eco would not be in the equation however.

 

There is no future in diesels. Take the little 2.7 eco and expand that technology into a 7.0 and you are talking about very serious power. Power that would shred the 6r140!

 

While the ecoboost motors are great, I have two of them, they will do a melt down at full throttle and full load up long steep grades.


A SD truck is subject to overloading and max towing in extremes and that is too much for this motor and its cooling abilities.
