That crazy manifold is great! By sealing all that stuff up, you get the bottom end torque of long tube headers, but so much heat that gets retained that cat light off time is the same for a car with an iron log manifold or a head with exhaust ports merged inside of it.

The first thing I am wondering is if there will be a Mazdaspeed3 and what will it be like?

I saw an episode of horsepower tv where they tested equal length long tubes,shorties and a 4 into 2 header.
They showed that shorties made less power across the board. Like 10hp/tq. The long tubes made the most hp. But the 4 into 2 pipes made 20tq more than the long tubes did,and right off idle. I contemplated a 4 into 2 header but they aren't made for a 4v.

But you can't speak about one type of engine and cross those results over to a completely different one. 4 bangers are 180 degree firing, completely different exhaust scavenging strategy from a V8 that fires every 90 degrees.

No CD player would be a deal breaker for me. Call me too old fashioned I guess.

To be honest, knowing how people car shop, that plug-in style stereo setup might turn off a good amount of people.

Thanks for the interior pictures of the 3. I'm not a fan of the exterior styling, but I *love* the very simple and high quality look to the interior. I prefer the look of the base model interior to that of the one with the LCD screen and the faux aluminum brightwork. That 3's interior reminds me of older BMW 3-series interiors. Very simple, nice straight lines, no gaudy flaired HVAC vents that look like ET's mothership, etc.

This design languge is WAY too absent in vehicles today, in my humble opinion.

The interior is enough for me to put that car at the top of the list if I were looking at small sedans to buy. I'd just have to live with the exterior styling. smile

Yeah, and your Chrysler is a luxury, top of the line performance model.
The fact that this kind of engineering can now be found in econoboxes is pretty darn impressive to me. Also, the fact the it comes from a company that apparently can go away just with the swing of Yen impresses me even more.

I agree. I was going to say this, but you stated it better than I could've.

...except that I also happen to like the exterior styling.

C'mon, shorty headers hardly represent state of the art, even in 05.

My overall point is that Mazda is not breaking much new ground here, just a thorough overall tweaking of the entire platform for efficiency while retaining their focus on driver involvement. Overall it's a GOOD thing and I like the company's intent, but too many here wave the 'skyactiv' flag as some kind of groundbreaking new tech. It's not. Just good marketing.

And they really are in a precarious situation, but you can bet they will team up soon with somebody. Lets just hope that won't dilute their offerings.

All I'm saying is that it is an impressive piece of engineering and fabrication. Just look at the bends and welds. If you drop the heat shield and the bracketry, this header could be almost taken for a limited production fit for some high performance car, not a mass produced item found in econoboxes under $20k. That's all.

I agree that there is nothing new or ground breaking in the Skyactiv slogan. However as a car enthusiast I appreciate that mazda went back to basics with reducing weight, stiffening the chassis, taking advantage of DI and making small tweaks overall. And it appears that Skyactive, while not ground breaking, does deliver promised fuel economy gains while retaining good power/torque figures without sacrificing driving dynamics.
CX-5 delivers some top notch gas mileage figures far a small SUV, so does the new Mazda 6. The same cannot be said about ecoboost or other small turbo implementations.

[quote=KrisZ]Here is a picture of the manual showing a tac. Perhaps it's digital and can be set to show either RPM or speed, depending on your preference?



Thanks, Kris. I was going by the photo captions in the Edmund's article. This makes more sense.

Count me in for a 6-manual with the 2.5, which they will eventually offer, at least according to Edmund's. Wonder if it will replace the turbocharged Mazdaspeed3?

I, too, am not a fan of the POD. Seems like an afterthought.

It's not just a caption. If you expand the below image and look in the right bottom corner, you'll see the top of the manual shifter, and yet, it has a speedo in the center, not the tach. Maybe it varies by equipment version?

Totally agreed. We've had 3 egoboost V6's in our extended family and none got much over 17 mpg. Most of the turbo'd engines waste a ton of fuel as cylinder coolant, and the folks that 'lightfoot' them to get mileage have issues like the intercooler condensation, etc.

And it IS interesting that Mazda has decided to spend money on the header fab when an old fashioned log of iron would cost next to nothing to make. Maybe the bean counters don't run Mazda?
