SkyActiv-X Review, glimpse of possibly what to expect in future CX-5s

I think it’s due to the strict oversight the EPA and others are implementing on Diesel engines right now. The VW scandal really hurt everyone in that regard. Gov’t has that tendency to go overboard to make it look like they are doing something when they should have caught it all from the start.
We get diesels from different manufacturers with no issues. Maybe it's just USA is so litigious that Mazda are being extra cautious
 
Could be they're not getting any [or conflicting] feedback/info from the feds, so they don't know where they stand, and don't know what to report.
Who knows that's why they need to communicate more
 
Do we know that the diesel delay is caused by Mazda, or perhaps the EPA/DOT/NTSB whatever?

What on earth are you talking about? Have you not heard about the massive diesel scandal? That literally sums everything up for you right there... mazdas Diesel engine is excellent and it shouldve been in the North American market many years ago, but its very difficult to introduce a Diesel engine into North America especially after what happened... how could it not be more clear to someone supposedly living in North America?

Well IMHO they should be communicating more about what is happening instead of leaving the public in the dark.

Its an awful time for them to be trying to introduce a Diesel engine. North Americas emission laws are absurd, the perception on Diesel is all wrong, Volkswagen quite frankly ****** up a huge market... its upsetting to say the least. Lets not also forget that Mazda was working on making a diesel engine that doesnt need the blue exhaust treatment or whatever, and then once the VW garbage happened diesel became off the radar for a small company like Mazda. I really hope we see the diesels here soon, but will we? Hell knows. I just cant deal with people in NA acting like they have no idea whats going on here.

Noone is picking on Mazda. BMW, Mercedes, Fiat, GM, and Ford all offer multiple diesel models for sale. In fact, VW was even allowed to resume diesel sales of vehicles on the lot which had been fixed emissions wise, in late 2017.

Let that sink in. VW was able to fix already built vehicles to pass testing, and sell them.

Mazda just can't get it done in the time they claimed, and they went dark. So. Much. Fail.

What do you think I was suggesting, Einstein?
A lot of people are blaming Mazda, but it ain't necessarily so.
Nobody but Mazda knows exactly what's causing the delay, not even you.

They are a small independent company trying to introduce the diesel.

Hope they have a smoother/easier time with the SkyActiv-X

I think with gasoline engines it’s not a issue. Look at Ford. They just came out with a three cylinder opposing piston engine that they are thinking of using for their F150 pickups. Now that kind of tech seems a lot more problematic up from than does the Mazda SA-X engine.

That's cool and all, but the sr20de in my old Infiniti g20 lasted 147k miles before I sold it (going strong, great compression numbers as good as new spec actually) and got 31mpg on 75 to 80mph road trips in that car with the 4speed auto, making 145bhp (2.0), and being just stupid simple and so on and so forth...all this new stuff? I ain't impressed yet. Even with my 2.5L cx5. At 200k+ miles, I'll reevaluate, but slap that sexy race header on my 2.0 sr20de, and I bet it'd make the extra 10hp all that wizardry and DI did in the cx5 2.0. Slap all the extra cogs behind it , and I bet mpg would be similar too.
 
Thing is simple solutions in the eyes of people doesn't cut it anymore. Hence more complexity.

I don't mind simplicity. If it does the job then great.
 
Cars have also gained a lot of weight because safety in that same time frame. It’s not an apples to apples comparison.

Mazda is a small company. They’re honestly probably more focused on Skyactiv X than diesel. It’s certainly going to be more accepted here in the US.
 
True that but when it reaches convinience arent they goanna be behind in technology since they are not putting any R&D......i think problem with smaller companies is that they don't have funds to pursue both technologies and have to choose one....anyway I'm looking forward to X

It is completely untrue that they are not putting R&D. Mazda has had hybrids in Japan for years. There is just not enough demand for them elsewhere and so their focus is tightened on what works best for them. When the time comes they will release electric vehicles. Next gen hybrid/electrics are already on roadmap for mid-2020s.

Perception on diesel isn't wrong. Its a dirty fuel that is difficult to clean and still be economical. Europe is revising its approach to diesel as well since every manufacturer there was skirting rules. Much further investment in it seems unlikely, at least for consumer applications.
 
It’s an uphill battle in the US the gas stations in town might have one diesel pump...... so unless you fuel up at truck stops that can be a pain. Then there is just the public perception.

I do think Mazda can probably snag a lot of former TDI sport wagens with the CX-5 and sell enough to make it worth it.

The Skyactiv X will likely have no issues at all as most buyers won’t realize it’s special in any way.

Opposed piston engines have been around for a long time, just not in cars. They've been used in aircraft, boats, subs, trains, and generators.
 
They had a group of scientists and other experts who concluded that a modern diesel like in the Euro VI in the CX-5 are cleaner than any current petrols.

I went to the dealership today. Service manager (me to him):"When are we getting CX5-D vehicles in America? They said we'd have them by the end of 2017." Him to me: "Well they also said we'd have Apple Carplay, didn't they?" ROFL! No prompting at all. Mazda knows what's up, we ain't gettin' anything more than we always have: A basic b**** that can have a good time on a budget, and sometimes that's nice, but don't pass her off as cultured.

I think the CX-5D is a pipe-dream for NA, honestly. All talk, no action. Just like the Mazda 6-D, was it?

I read somewhere a next generation diesel is in the pipeline
 
One thing I'm curious about is whether spark-initiated compression ignition will have difficulty passing stricter NOx limits. As I understand it, the higher the combustion pressure and temperature, the more NOx is produced, and the higher the proportion of NO2 to NO. That's why diesels need urea injection to stay under the limits here in the US. The efficiency and torque gains from SPCCI are dependent on achieving a higher effective compression ratio, high enough to cause spontaneous combustion of a very lean fuel-air mixture in most of the combustion chamber. That would seem to be a recipe for higher NOx than current spark ignition engines.
