Reliability is a huge deterrent from current diesel truck owners...along with the extra cost in the initial purchase. It use to be you bought a 200hp diesel that putted along for half a million miles with nary an issue, then they all got wrapped up in the HP race...kinda a race to the bottom in my opinion. 6.0's and 6.4's have earned their bad reputation in the diesel world...but lb7 duramax are just as problematic, and Cummins have plenty of their issues too. We sell reman motors to lots of people, all the big 3 motors, and lots of tow truck companies are buying gas engines when they buy new vehicles for their fleet. Diesels will always have a necessary spot for bigger hauling needs, but unless they address reliability they'll all run diesels out of the truck market. Maybe fords new 6.7 is a little better, I know duramax have gotten lots better...Cummins have gotten slightly better too, so hopefully we are turning that corner.
as far as diesels in the greater market place, Chevy is going to offer a diesel in their cruze, vw has been a big vw advocate for a long time, obviously with their European roots. Even jeep is offering a diesel in the wrangler next year and already offers one in the grand Cherokee. I'm in the market for a diesel vw golf right now. People routinely get 50+ mpg on the highway with em, and they're way less gay than a Prius. In fact the Guinness world record is held by a vw diesel, like a 08 or 09 jetta or Passat that drove through all 48 continental states and averaged like 67.5 mpg, albeit at like 5 under the speed limit, and I think they inflated the tires some. Diesels have gotten way quieter, just about as quiet as gas motors, and the potential for effeciancy is so much greater...but with literally all new diesels needing treatment of some type, I'd rather buy a used one without it. Its another system, another aspect of maintenance.
In LA, 80% of the pollution came from the ports, diesel engines idling for days, they've converted a lot of that to electric generators and all, and cut emissions down by half, which dropped total city emisions by like 20%. I heard this on NPR the other day, might not have all the specs spot on bit that's the gist of it. The damn government needs to stop penalizing diesels so harshly...they're cleaner, and growing fast, but they'll squash that like a bug if they keep driving up cost and driving down reliability with all the emissions stuff. Instead they'll push for electric or hybrid cars, but they don't take into account the full scope of bow those effect the environment either. I've seen reports where diesels still win based on energy to make and dispose of batteries for them.
Someone made a good point that they auto manufacturers will only do it when its profitable, that's very true. It'll take tons of people to realize the benefits, but IMO the benefits are squandered when you count in how much emissions stuff you have to deal with. Honestly I think diesels will be about where we are now in ten years as long as fossil fuels are still the main source of automobile transportation. Maybe see more in passenger cars, probably about then same in trucks. Most people I think can do what they need with a gas motor in their truck and avoid the extra initial cost of diesel whem purchasing and the added cost and hassel down the road too. I think maybe 10-20% of new diesel owners actually take advantage of what a diesel cam offer over gas, in terms of pulling capacity and all. Someone who thinks they need a big rig to tow their 16' boat to the lake for the weekend, or going to pick up a load of bricks from home depot to finish their honey do list is kidding themselves that they need a diesel. I damn sure don't need a diesel, but the lure of all that tire roasting torque and not worrying about pulling a 10k lb load is nice, but I wouldn't want to deal with all the extra crap involved with the emissions stuff.
