Mazda can just not get enough use of the smiley face design concept...

You mean this;


I went ahead and bought one. Diesel, 4x4 and I chose the auto. The 2000KG towing capacity will come in handy. (When I get it that is... September delivery FML...)

 

Yeah, I want that.

What are you towing?

 

Direct injection has to overcome compression.

My 2012 Cummins ran at 22k-24kpsi, and had a shim to relieve pressure after that.

I put in a thicker shim to raise the cutoff pressure to match the added boost. Now I see 26k-28k psi

 

Hopefully I will be towing a dedicated track miata sooner than later...
Keeping things street legal over here is a pain and when a appropriately sized daily is comfortable, can tow AND get good milage I see no reason to keep it that way.

Until then I`m not really towing anything. Maybe my boat once every second year... (Small boat)

 

It would be pretty awesome to be able to pull with that CX-5. I wonder if the trans can take the abuse? If I could get away with that I'd totally run to the dealer and finance one.

Cue the "you need a BNSF train to tow a Miata" crew

 

I did calcs on this somewhere. You save gas by turning off the car any time you're going to be stopped more than 3 seconds. At least I do on my megasquirted miata.

This is why BMW puts that feature in their cars. It's roughly as effective as sucking off the EPA test certifier.

I looked at the CX5 gas version when I was car shopping. I don't want a diesel for various reasons.

Ultimately a loaded CX5 with manual trans and AWD was not significantly cheaper than the way-more-baller MINI Countryman I got. Plus it was uglier. Plus I had to spend 5 minutes in a Mazda dealership and extract about 15 salesmens' hands from my pockets when I left. Dirty.

 

is the diesel coming to NA? google fails to help me... would gladly look at that for a robust wifeymobile (in AWD though for snow)

 

Brother in law got a white CX5. I drove it, needs more power. but it was brandy new and I wasn't going to beat on it. The steering wheel was nice.

I have a new class 3 hitch for it in my garage.

I'm personally waiting for the new 2L ecoboost Escapes to show up at the local Ford dealerships.

 

That's gotta be the happiest piston I've ever seen

 

A couple of months ago one of the local dealerships brought two CX-5s to a club meet. They seemed pretty well appointed for $22K cars. I think the sales guy said AWD was a $1K upgrade. The sales guy and one other guy who had one on loan both said it feels pretty gutless on acceleration, and these are people who are used to driving bone stock Miatas, so, yeah......

The Mazdaspeed 3/6 with the 2.3 DISI run something like 1800 psi fuel pressure and have been doing so for 6-7 years now. There's a regular pump that sends fuel from the tank, and a second high pressure fuel pump that's driven mechanically by a camshaft. The high pressure pump internals are typically upgraded before trying to make significantly more than stock power, and the injector seals are another possible failure point. I didn't pull the engine cover or otherwise poke around the CX-5 to see if it had a similar cam driven high pressure pump, but I did notice there's a ton of room between the engine and the firewall.

The pic Brain posted is an upgraded/revised piston for the 2.3 DISI.

This is the Skyactiv gasoline piston:


Skyactiv diesel piston:

 

i think the piston i posted was actually a weisco.

 

Yes. What I wasn't clear on was whether Wiseco's design (or CP's design that Wiseco produces) is the exact same as the revised Mazda version, or has a more extreme profile. Doesn't matter to me since I'll never build a DISI motor, I just ran across it while researching whether I should even consider a MS6 for a daily.

 

FWIW: The MZR-Turbo uses an electric lifter pump in the fuel tank and a cam driven booster pump to increase the pressure for direct injection, which is around 2 - 3kpsi. If the dealer has to service the fuel system in any way, if possible they'll pull the fuel pump relay and start the vehicle to run it out of fuel in the system, then they can crack open the high pressure side.

I had a TSB on my MS6 for the high pressure fuel pump and watched the guy replace it.


Y8s, you think that fugly mini thing looks better than a CX5?? Sorry bro, that thing is one of the worst looking german vehicles I've ever seen.

 

i pity the fool that doesn't realize this and tries to pull an injector.

 

what you havent taken 3,000psi worth of fuel to the fingers/face?

you haven't lived

 

That. Would. Suck. lol

 

I just watched the video finally.

So basically, DaveColeman took some of his banned LeMons technology and stuffed it under the hood of the 3. I get it.


Seriously though, am I seeing the basic components of a stratified charge setup similar to the old hondas of yore? Little bowl in piston to make tiny combustion volume, multiple squirts per cycle, high atomization, dinky undersquare bore...

+1 CVCC lives again. There is nothing new under the sun.

 

Your options were an awesome looking, small SUV or the ugliest pug-nose car on the market, lol. The Mini is also nowhere near reliable.

 

Am I being a brand------ or is Mazda about to explode with market share and should I run to a broker and start buying shares? The only problem with the newest generation of Mazda cars is that I can't work on them in my garage because they are way too high tech for my child's brain. I really think that 2.2 turbo diesel is going to change cars permanently for us. This hit me when I was watching leMans, engine technology is going to new places and diesel is the way. I expect Mazda to crush LMP2 next year.

Well...the diesel may change cars if the EPA doesn't get involved.
