Is Ford really working on a new 8.0L Power Stroke turbo-diesel engine for their Super Duty pickup truck lineup? There is a prevalent rumor that claims that this information leaked and that this new turbocharged diesel engine with two sequential turbochargers will produce at least 600 hp and it would not use DEF emissions system. Does this make any sense? Let’s dig in!
The rumors say that this information is based on “a leak”. However, there is no source that specifically says what the source of the leak is or was. Some mention that it is based on a patent filing, while others suggest that it’s based on a leak from an internal engineering meeting that happened earlier this week. TFLtruck checked into this, and we cannot find a relevant patent application that mentions a larger displacement turbo-diesel engine or sequential turbos.
It’s true that the current 6.7L Power Stroke V8 engine traces its lineage back to the 2011 model year. The engine has been updated several times. It’s now the segment leader for power (500 hp and 1,200 lb-ft of torque). According to our real-world testing, it’s also the leader in efficiency. We compared it directly to the GM 6.6L Duramax and the latest Ram 6.7L Cummins. The high-output Power Stroke return better empty and towing efficiency after several tests. The new 6.7L Power Stroke is also the engine that uses a lot of Diesel Exhaust Fluid (DEF).
Turbo-diesel engines operate with very high temperatures and pressures. This is a condition that creates a significant amount of harmful NOx emissions. The more power you make and more efficient your new diesel is – the more NOx it potentially creates. This is counteracted by the EGR, DOC, DEF/SCR emissions systems. This is one of the reasons why we noticed that Ford engines use a lot of DEF.
We reached out to Ford for comment on this rumor and we have heard nothing back. Manufacturers usually do not comment on future products or rumors. They announce it when they are ready.
At this time, I see no reason to significantly redesign this engine. The owners are more worried about reliability and longevity. If increasing the engine displacement allows for more reliability, then it’s welcome. However, there will be growing pains as there are with most new technologies.
What do you think?
