Nissan Titan XD Cummins Diesel Fuel Mileage
Looks like the Titan/cummins/aisin setup falls short on the fuel economy both unloaded and loaded. Not sure if this run included a regen, but I'm really surprised how poor the unloaded fuel economy is...

I am not sure what advantages are that Nissan is shooting for. The price on the truck tested was around $58k. Fully loaded I am sure. The MSRP on my 2015 completely loaded LBZ 3500 was 64K. The Nissan specs about the same as the first LB7 Duramax trucks (considerably less than the current big three). The issues are that the MPG is not good enough, the capability of the Nissan trucks is not enough to compete with the HD offerings of the big three, and the price is too close to the big three to make do with the lesser capability (but comparable mpg). Unless you just want a Nissan there is not anything really compelling about it.
I personally felt that for this to work for Nissan they would really have to thread the needle. I think they missed and stuck themselves. The MPG aspect is important, but when I saw the specs, I knew that the powertrain would have to be beefy to hold that power, and so the weight is going to be there which mean less payload. Lastly the price component was huge. As it turned out almost 60k for a pickup with 60-75% of the capacity of a big three pickup is a complete miss. I think Ram and GM will prove to be much more successful in the diesel half ton market.
As to blended fuel, I just got back from a 2K mile trip to California, blended fuel (severely leaned out as it was minus 20 in Idaho). I got 17 mpg on the trip not pulling anything. With Summer diesel, I would see a couple mpg improvement typically, but it really depends on how much number 1 is mixed in with the #2. So the leaner the mix, the worse the power and subsequent mileage. How much better the Nissan will do with Summer diesel really depends on how the fuel was mixed.
