I still think the 4 cylinder Cummins that Nissan had in their show truck would be amazing in a base 2014 Silverado for around $22k sicker, hint GM, hint GM.

About 6-7 years ago, GM had a light duty V8 diesel, but they scraped it before they ever produced it. They might be bringing it back.

Is the diesel for better mpg, or higher towing, or both?

I wouldnt mind a big pickup that could push 25-30 mpg, if that is even possible. Diesel electric hybrid?

RAM 1500 already has a pickup with a estimated fuel economy of 25MPG highway in its 3.6 V6 and 8 speed auto.

And that's the rub. The fuel economy numbers we are hearing for these diesels is not extraordinarily higher than that of some of the gas powered trucks. Given the generally substantially higher initial purchase price of the diesel, plus the significant extra cost of diesel fuel (gas is currently around 3.52 a gallon, diesel is around 3.86 a gallon - about 10% a gallon higher on average), payback is going to be an issue unless placed in the right duty cycle.

I was once on this bandwagon - give me a mid-range hp diesel motor with decent torque (call it a mid range power option) with substantially higher fuel mileage and I'd bite. Then gas and diesel prices flip flopped so diesel is higher priced (and has been for years here), and gas rigs have steadily been doing better at fuel mileage, while diesel options have struggled now that they are saddled with all the emissions gear... and well, now I'm not sold.

I coulda sworn I had seen a site that did an mpg test while towing. And it was impressive--like 20 while pulling several thousand pounds. Diesels tend to drop less mpg under load--less of a need to drop down a gear, less frictional losses, probably other factors too. Until Ecoboost came along one either went diesel to get lots of umph at low rpm--or just got the biggest motor they could.

My wife's Camry has more hp but less tq than my Jetta. I've always preferred how my engine lays down power off idle though, while the Camry needs rev's to do anything. Pure personal opinion. I like how diesel drives, but for my mild usage the TCO simply isn't there.

Diesels lost a lot of their advantage over gas motors in the past 10-20 years, modern good fuel injection really closed the gap between the two.

Back in the 80's the advantages were large, even in the 90's. But these days the gas motors are cheaper to run and last just as long.

Part of the reason is the silly modern emissions regulations that really hurt diesels in this country.

Set up properly (good gearing, properly sized motor for the load, etc.) a diesel will get better mpg unloaded and towing lighter loads, as well as in applications with significant idle time. However, if you're towing heavily loaded in the mountains, the mpg difference shrinks a lot as both engines are under enough load to be close to peak efficiency. The key is that gas engine efficiency drops off faster as you stray from that peak while a diesel has a better load / fuel consumption curve.

Copying the Titan? I thought the Titan was supposed to go away and be replaced by a rebadged Ram.
