This question revolves around the MKS thread as well. Since we know the Nano will get better HP per liter than the 3.5EB, will there be several levels of performance with the same engine, in the same vehicle, similar to this quote from the F650 article?
"The three diesel power levels available for the 2016 Ford F-650/F-750 are:
270 horsepower/675 lb.-ft. torque (best-in-class standard)
300 horsepower /700 lb.-ft. torque
330 horsepower/725 lb.-ft. torque
Multiple ratings provide customers with the flexibility to scale engine power to work applications and operations."
Same engine denotes nothing changes, so of course it is not the same if output is different.
In the case of the Diesel applications, I don't know of any major changes, other than new cams, timing and possible turbo sizing.....specific to the needs and objectives of that class truck, vs an F250 with entirely different speed ranges, gearing, etc.
Obviously it would make zero sense to go through the entire process of component changes, just for slight power changes. And when I mean slight, I am referring to it's scaled proportions. When you start with 800tq and drop to 700tq, that is what, a 12.5% delta. For reference, a similar drop with 300tq, takes you to like 270 or so.
As for the Nano, there is in fact different upper end components (heads, cams, intakes, covers, etc. There is no reason to change a short block, other than bore/stroke. The tooling cost alone is major to shuttle a major component through a factory with different bore spacing or pitch, for example. Heck, just the shipping pallets along is a major cost.
Nothing new. Ford has been doing this for years.
I know that some here would not be satisfied until every single component is unique, but they need to get real. Ford's misison is to deliver great product and.....AND increase shareholder value.
Hard to do if you quadruple complexity and cost and reduce profit.
