Larry,
Can I ask what business you are in? Plenty of truth to your statements.....but saying the 6.2 is not a reliable motor is news to me and I have worked with many fleet companies who run them. I have been out of that business a few years though so maybe as they have aged they have started having problems. I would argue though that the two best gas engines in that category are the 6.2 and gm 6.0.
I am a field service engineer/fleet service manager for a truck and engine manufacturer. You see our trucks and buses on the road every day. We were first known for agricultural equipment up until the 80’s. We are also the company that built the Powerstroke diesel up until Ford build their own 6.7L. I handle the UPS and GSA accounts and a couple school bus dealer conglomerates in the western US. I cover vehicles from stepvans with GM gasoline engines on up to Class 8 over the road semi with Cummins and our proprietary engines. We have several different divisions that use various powertrains from many different engine suppliers. When a person deals with hundreds or thousands of a widget they tend to form a different opinion than others that have exposure to one or a hand full of the same widget.
As for the love affair for diesels "dying," that's a bold statement, and one that most of the big manufacturers seemingly disagree with; I'm not sure why they are intending to bring diesel options to the mid-sized and full-sized markets if the so-called diesel love affair is truly over.
It is a bold statement but it is a very real statement. I must go on record to say that is the opinion of mine and not necessarily the opinion of my employer but I can tell you the major fleets that run Class 5 through Class 8 trucks are dying for something other than diesel. It is not the actual diesel they don’t want anymore, it is all the baggage and cost associated with today’s diesels. If you subscribe to any of the fleet industry mags or attend fleet conferences such as SAE, TCM, ATA, NTEA, etc. you will hear the cries for more gasoline powered larger vehicles. Modern diesels are an absolute expensive nightmare to maintain due to the aftertreatment systems used to clean them up to meet federal standards. Big fleets are tired of the excessive downtime and excessive cost to maintain them. Obviously, it is going to be a long time before there an alternative powertrain that can pull 80,000 lbs. down the interstate completely make diesels extinct but you see natural gas semis everyday on the interstate and probably don’t even realize it. Those are diesel engine architecture but they are spark ignited and run like a gasoline engine. The advantage of running spark ignition on natural gas, propane or gasoline is the fact the expensive aftreatment system is not required. The reality is not every vocation really needs a diesel which is exactly why UPS moved to gasoline engines in every GVWR a gasoline engine is offered. You can buy A LOT of gas for the savings of not going diesel. Same exact reasons why GM, Ford and PSI are all busy engineering new bigger gasoline engines. I can assure you there are some monster gasoline and gaseous engines out in the field being tested from 9 to 15L. More and more RFP’s coming out from fleets are strictly written for a gasoline powertrain. In many cases, right now today a gasoline engine doesn’t even exist in some of those applications….that is today, tomorrow will surprise may people.
The love affair is dying but you’re right, not in the retail segment. Right now diesels are becoming more and more popular and available in small retails vehicles but the driving factor is entirely…..
First, the retail onesie twosie customer strictly buys on emotions (WANT). Look how many times we have read over the years where people WANT a diesel in a Jeep, WANT a diesel in a Tacoma (Toyota is too smart and business savvy to offer a LD diesel in the US), WANT a diesel half ton truck, WANT a diesel lawn mower, coffee pot, blender, blah, blah, blah. Retail customers tend to be suckers so they might as well offer a diesel and make a buck while they can because if they don’t someone else just may. That is the business sense that GM used to justify the diesel Colorado. They had zero percent market share in mid-size trucks where if they wanted a piece of the pie they had to punt and punt hard…..now they have a large piece of the pie but still not a threat to the Tacoma. Is the bold desperate punt got to work for the long term? Time will tell. I can’t wait to see how many repeat customers will go back and buy their second RAM 1500 with the 3.0 diesel or Colorado diesel. You can’t blame manufacturers for offering something customers are willing to pay for.
Second, the more diesels the manufacturers offer in smaller vehicles the more it helps with CAFÉ across the board. Well, that was the thought up until recently. Who knows how things are going to go in the new administration. Regardless, don’t laugh at the people that buy a small diesel or hybrid because they think they are going to save money, save fossil fuels, save whales, save baby birds or whatever in the long run… instead thank them because if they didn’t the rest of is may not get our big V8 gas engines in trucks and sports cars.
Third, for those that think VW is the only one in the world that is cheating think again…..VW is just the one that got caught. Diesel emissions regulators probably won't get any lighter even with the current administration.
Lastly, don’t expect the trend of diesels in light vehicles to be wide spread or long lasting one (may go 5 to 10 years if that). LA and New York City are already talking about following London and Paris in the diesel engine ban while other municipalities will most likely follow. Probably not today or tomorrow but in the next decade. It does seem awkward to think a gasoline engine makes bunny huggers happier than a diesel.
Again, all of these reasons is why GM, Ford, PSI and several others are all busy engineering new bigger gasoline engines. The diesel cycle reminds me of Lambo doors. One day some pocket pants wearing chappie will pull up to a diesel pump in his rattily 2020 Jeep Wrangler while there will be a 30,000 lb. dump truck at the island next to him buying unleaded gasoline while they look at each other thinking each other is crazy.
