You aren't comparing apples to apples, like you think you are.
The 2.5L 4-cyl is a Skyactiv engine. It gets V-6 performance with hybrid-or-better mileage numbers, without those batteries that are so bad for the environment.
Note: the 2014 doesn't even have a 6 cyl option anymore.
The 2.0l 4-cyl performs like the old 2.5l 4-cyl, but with better mileage.
The 2.5l 4-cyl performs like the old 6-cyl, but with extremely better mileage.
And the Mazda6 has traditionally been bigger than the Altima, but I admit I haven't compared the most recent models.
And while the Altima gets high marks for "fun to drive", usually equal to the Mazda6, I still think there is a slight difference in feel, and the Mazda6 suits me much better, and so is, hands down, the better car for me.
I still have a 2010, still love it enough I wouldn't trade it for a 2014 Altima straight up.

what do you base your statement on?
"The 2.5l 4-cyl performs like the old 6-cyl, but with extremely better mileage."
u can't be serious?

Haven't you heard anything about SkyActiv?

I have to agree. Skyactiv is more marketing than engineering breakthrough. The CX-5 was so underpowered with the Skyactiv powerplant that they are already offering a new 180 HP engine in the new model.
More efficient for it's size, but not really more powerful.

Your statements are ridiculous. Skyactiv is not a turbo or drastic increase of hp or torque. It is an overall system of body/engine/aerodynamics etc that provide for excellent fuel economy with decent power. It's designed for good MPG not power comparable to much larger engines. The 2.5L skyactiv engine has something like 185hp. There is no way it compares at all with the power of the 273hp V6. The V6 has been dropped because it sucked gas, not because the 2.5L performs like it. The 2.0L engine has something like 150hp, so no it does not perform as good as the 2.5L but gets a lot better MPG.
Mazda has decided, as far as we know anyway, to delete the V6 and just go with the I4 and the diesel for CAFE reasons not because either performs like the old V6. Maybe they'll come out with something a little hotter or more zoom zoom but for now they are toning down power for MPG.

kyfdx-
I do not agree that SKYACTIV engines are on par with V6 variants (obviously), your assessment of what SKYACITV is is way off base. Considering you represent Edmunds, I would assume you would know better.
Let me help shed some light on exactly what SKYACTIV Technology is...
To start, Mazda did a boat load of engineering to create power trains that increase efficiency and power without sacrificing driving performance. They used a "sky's the limit" approach to achieving their goal. That is where the name came from.
In the engine, Mazda uses a innovative cavity piston design to harness fuel energy that helps the fuel burn more efficiently and creates more power. Mazda also uses one of the most advanced DI systems on the market injecting fuel in at over 2900psi. It injects fuel in both the intake and compression strokes for engine cooling, which is why Mazda can run 13.1 compression on 87 fuel. Also, the DI has a 6 hole injector in each cylinder which is specifically designed to inject fuel at precise points for perfect fuel/ail atomization.
Mazda also reworked cooling passages, oil passages, cams, piston rings, connection rods to create less friction, down about 30%-70%, depending on the part, from the previous MZR motors.
Mazda also uses a 4-2-1 header exhaust manifold, this is not new to the market, but Mazda found a way to make it work with a horizontally mounted engine, something that is not easy.
The 2.0L engine used develops 155ph and 148ft-lbs. Currently in the Mazda3 is far better than offerings by Hyundai, Toyota, Nissan, Honda and Ford as Mazda is the only one who gets 40mpg w/o any special FE package and no CVT tranny. Nissan can get there w/o any FE package, but needs a CVT and FAR less HP to get there. Mazda's engine is obviously superior. The CX-5 gets a pass based on displacement, but the 2.5L offers over 20 more ft-lbs than the CR-V and gets better city and average FE. The Escape has proven to fall short on FE promises and the CX-5 has not. The Rogue, Santa Fe, 2014 RAV4, Sportage all still fall short of the 2.5L CX-5 in both power and efficiency.
The real beauty of SKYACTIV is the automatic transmission. It uses a very small torque converter for speeds lover than 5mph and then a multi-disc clutch for shifting, which is very similar to a DCT. No one has done this yet. As a result, you get CVT-like efficiency with the direct shift feel of a DCT and the smoothness at low speeds of a conventional torque converter tranny. This is why you see the Mazda6 match the fuel efficiency of the Altima without using a CVT. If you notice, any other cog tranny's efficiency is a bit off the mark from Mazda's in this segment and they sure don't provide rev-matching downshifts for great real-world driving capability.
There were also many enhancements to the body and chassis to reduce weight and increase strength by using ultra-high tensile steel. Mazda uses more than any other manufacturer. This aids in efficiency and safety.
This is really an abbreviated version of what Mazda did. You can search YouTube and Mazda has plenty of videos describing what they have done.
Is "SKYACTIV Technology" a marketing tag? Absolutely. But, what Mazda has done IS real and some of it is true innovation especially from a company that produces affordable vehicles. Mazda's engineers have really come up with awesome technology, IMO.
Proof is in the pudding as consumers have flocked to Mazda's new tech and sales have been above and beyond what Mazda was expecting. If you look at the year-end sales results, Mazda sold 123,000 Mazda3's (most ever) with 69% being SKYACTIV equipped models. Mazda stated at this time last year, they did not expect to sell more than 100,000 Mazda3's for 2012. The CX-5 sold 43,000 units, far beyond what Mazda ever thought it would sell in years one in the U.S.
I hope I helped clear some things up for you. For more info, visit Mazda's web site, or YouTube for the cool videos they have posted.

You obviously know more about it than I do.. But, 155 HP out of 2.0 liters is nothing special. More efficient than a comparable 4 cylinder? Sure.. A substitute for a V-6? Not even close.. underpowered for the CX-5? Seems to be the general consensus.
Which was the subject of the post I was responding to..

Drove a 2014 Grand Touring today. While the exterior is gorgeous and it drove nicely, the interior is nowhere near as nice as the new Accord. The driver's seat felt hard, whereas the Accord's was really plush. Also, the Accord's center stack is much more modern looking. The nav system in the new 6 is pretty antiquated looking. As of now, an Accord EX-L V-6 with Nav for about the same price as a Mazda6 Grand Touring is much more appealing...especially the tons of extra power the V-6 offers over the 4-cylinder.

As you can see, I agreed with you on the V6 comment. But, in context, the 40mpg 2.0L is pretty good even with 155hp. Mazda should have used the 2.5L in the CX from the rip.

Thanks for clearing that up! I figured you guys were more in touch with your editors/evaluators. My apologies.
