Agree with you on this. I would consider a CX-5 Diesel with Signature option (who knows if they will offer this?) as our next car.
US Diesel's big splash introduction

Maybe as a future update before all new version is released
Diesels don't need revving as you said all the torque down low is what gets them moving

The dealer we almost purchased a CX-9 from (who still calls me) told me a week or so ago that they have no word on availability yet. Regardless, there's no way I'm going to place any order in advance. After all the talk in recent years, prove to me that you're actually going to bring it here by actually bringing it here. If it arrives with the specs we expect at the price we expect, I'll buy it.

Well, that is good news. I do think if they bring the diesel to the USA, they will make sure things go right, as Mazda can't afford a complete bomb. That is why I think the OP might be on to something regarding warranties and such.
I definitely would rather have the diesel, but couldn't wait for it unfortunately. I had a 2005 VW Passat TDI and loved it. Bought it for $23000, put 110,000 miles on it in 3 years, and sold it for $15,000. A guy actually flew one way from Denver to Texas to get it. He called me a few years after that about an electrical issue he was having and he had over 200,000 on it at that time and said it ran perfectly. Best vehicle I've ever had for highway cruising.

There's nothing wrong with the engine. It's very simple in terms of it lacks an ignition system, it needs an oil and filter change and a periodic fuel filter. If it has an Achilles heel, it has to be modified to control particulate emissions. The European version does it be post injection regeneration but yours will use Adblue dosing.
It's a cracking engine and there is no need to be nervous about it.

If I am not mistaken, the DPF prefers longer distances traveled so it can warm up and function properly. So this diesel engine is more suited to longer distances travels rather than short/quick daily commutes (uhm)

Mine regenerates about every 100 miles. It will only regenerate when the engine is right up to normal temperature as the regeneration is the burning off of the particulate matter in the exhaust filter. It takes about 20 minutes typically so if the engine is switched off before it is complete, it will start again somewhere along the full process. In that respect, you need perhaps 15 minutes to warm it up then 20 minutes to regenerate- 30-40 minutes from cold or 20 minutes from hot. If that isn't within the operating parameters of the user then there could be a case of "unsuitability". You're diesel will be different in that it doesn't use regeneration to purge the filter, it drip feeds animal urine into the exhaust which clears the particulate matter. Of course it could be that the US version will use a combination of these methods in which case, short trips won't be good for you either. Diesels are extremely thermally efficient and most of the heat generated in combustion goes out through the exhaust so they take ages to warm up. To help speed up warm up the new CX-5 diesel has a radiator shutter in the lower air intake. That entire big gaping grille is a phoney and just for styling. The radiator sits behind the lower intake. Another snag with a long warm up time is the cabin heater doesn't warm up quickly either. For that reason all the diesels have a PTC (positive temperature coefficient) heater that sits in the intake of the heater. It provides electric heat to bolster the regular fluid heater. It doesn't provide much heat but it takes the chill off. I can show you PDFs of these features if you are interested.

These explain the European DPF system in more detail BUT keep in mind yours may differ. I suspect that the delay in getting your diesel is the development of the urea injection system.

My understanding is that the adblue is required primarily to address NO2 emissions, which are set at lower limits in the US than elsewhere.
The DPF is still required to filter particulates out and there will still be a regen process, same as any engine that uses a DPF.

Yes you may well be right - the US system hasn't popped up in the workshop manual yet. So in that case, diesels are probably not a good idea for the retired couple that only pop down to the store. Most "normal" users won't be effected by a blocked DPF but for those that do, the dealer can force a regen. I can show you how to do this but only on an as needed basis. It involves the shorting of the test point which then sends the engine into an unattended cycling process of revving the engine at various speeds. What will effect everybody to a greater or lesser degree is the dilution of the engine oil. The post injection method sprays neat diesel into the exhaust which acts like an afterburner on a jet. The DPF is superheated and man you can smell hot metal and rubber when it does it. Some of the diesel gets past the pistons and into the sump. There is a third mark on the dipstick to indicate to indicate the limit of dilution but the engine also measures viscosity and may mandate an early oil change. This business of you US guys going off with your favourite brand of oil is really risky unless you stick rigidly to the recommendation for 0W/30 C3 oil. C3 means it is low ash content which caters for the opposite problem - oil passing the pistons to the upper cylinder which of course feeds the DPF with particulate.
You can see there is some commitment in running a diesel engined CX-5. The up side is this tremendous torque output which really provides an interesting driving experience. The fuel consumption is good providing you don't grow horns - you can really piss off the big bore slammed to the floor Hondas but at a cost. The regen also lowers the average fuel consumption but I can easily get 60 mpg on a highway trip. That's about 50 mpg on a US gallon.

Yes, we'll have both DPF and DEF for SkyActiv-D 2.2L diesel in the US!
It may be for a small subset of users here in North America but raising the tow rating on the diesel CX-5 would be an extremely positive note on the spec sheet compared to competitors. A tow rating of 3000-3500 lbs (1361-1588 KG) opens up a lot of possibilities. Make it clear one needs electric brakes as well on the trailer.

Exactly. Unfortunately there're many senior citizens in the US are getting CX-5's.
People if they read these procedures like I did, (and thanks for many detailed documents on SA-D) they would definitely have a second thought of getting a SkyActiv-D diesel, such as this Compulsory DPF regeneration in the long mode: (PM = particulate matter)
So no matter how much Mazda has done to prevent the oil dilution (raising) issue, it potential still can happen. That's why the additional "X" mark on the oil dipstick. Unfortunately most US car owners aren't getting used to use "Flexible" oil change interval with oil life monitor, I can see this's going to be a challenge to overcome on oil change practice for diesel owners and Mazda dealers as most of them use fixed OCI!
This right here will be an impossible task for Mazda North American Operations who can mandate a 0W-30 C3 diesel oil as the only oil Mazda diesel owner's can use, because they can't!
Yes, people need to have commitment to enjoy a Mazda CX-5 diesel, especially in the US!

It's not exactly plain sailing I admit but it's not so unpalatable to European owners - diesels account for the majority of vehicles. You are right, nobody can make you choose your oil but think of it like having to put diesel in your tank instead of gas, it's a necessary thing to use the right stuff and you will pay for not doing so.
I'm currently locked in an email battle with Mazda because we don't get a choice. I like the diesel for how it performs but diesel engines are being demonised here and the big cities are set to charge for entry by number plate recognition. From next year it will cost about $15 a day to enter London. Despite this, Mazda offer all but the basic 2WD manual with a gasoline engine. All the autos and AWDs are diesel only.
I would put a deposit on a 2.5G AWD auto today but it is not an option.
