2016 Honda Accord 2.4 S Navi vs 2016 Mazda6 Skyactiv-D

Executive sedans were once considered the de facto upgrade for those looking at something more luxurious and sophisticated than a compact car. However, with the proliferation of other choices out there, not to mention the increased specs of the compact cars they’re meant to upgrade from, the executive sedan segment is dying. Today, opting for one of these Japanese mid-sized sedans likely means you’re looking for something chauffeur-driven or something cushy after a long day’s work in the board room.

Be that as it may, there are two executive sedans that don’t fit this norm. Though they’re pretty good sampled as a passenger, they’re best savored from the driver’s seat. These are the 2016 Honda Accord and the Mazda6. The Accord has long been the standard when it comes to sporty mid-sized sedans. Throughout the years, it has always produced a sportier flavor, but still managing to balance fun and comfort. But there’s a new challenger out there, hungry for its throne. Known as the Mazda6, it’s now imbued with style, power, and poise. The question is: can it finally beat the Accord in a head-to-head brawl? Well, it’s time to fire the driver and find out.


In their current guise, neither the Honda Accord nor the Mazda6 could be considered as new. Both have been around for a while, with the KODO-fied Mazda being the first to appear in showroom floors in 2013 while the Honda arriving about a year later. Of course, it’s a given that both of these cars have seen substantial tweaks to modernize its styling.

First up is the Mazda6—a car that Mazda designers believe they have struck gold with. Apparently, the design is working (and aging) well that updates were brought in just to unify its look with the rest of the Mazda line-up. Some are arguing though that the designs coming out of Hiroshima are starting to look the same, and rightfully so; but there’s no arguing that it still looks great. It’s especially true with the Mazda6 which happens to look athletic and graceful. In fact, the subtle elements such as the headlights, bumpers, and grille have managed to make it look wider than the Accord—a feat considering it’s actually 10 millimeters narrower than the Honda.

Honda has pretty much done the same thing with the Accord, though this time, it’s not for trying to create a unified look across the product range. Sure, there are elements like the Solid Wing face, but the tweaks have been done to actually clean up the aesthetic mess that the Accord once was. And boy, did Honda get it right this time. The cleaned up look makes the Accord look more regal and believable as an executive sedan than a body racer trying to grow up. That said, there’s still something off with the way it looks. There are lots of needless gashes and lines sprinkled around. It also looks top-heavy, emphasized further by its smallish 17-inch alloy wheels.

Winner: Mazda6


As captains of industry serving as its primary market, both of these cars have refined interiors that easily justify their price tags. Yet, they’ve also been re-worked, answering to criticisms that they’re offering an experience that too close to that of their small compact sedan siblings.

This year, Honda has swapped certain interior trims to make the Accord look and feel more modern. The faux wood accents have now been minimized; now only found as an insert on the steering wheel and dashboard. Piano black inserts with metallic flakes have taken its place elsewhere from the switch bezels, center console, and even the area surrounding the gear lever. It’s not as scratch-prone as the one found in the Mazda6, and that’s already a plus. The paneling aside, the biggest change here is the new infotainment system. It still uses a dual screen set-up but this new Android-based system is light years better than the old set-up. There’s still some lag to the response, but overall it’s not too bad. And speaking about the dual screen, the larger 8-inch screen is better utilized now and acts as a display for the Lane Watch blind spot, and rear parking camera. Things like navigation are displayed in the slightly smaller 7-inch touchscreen.

Next to the re-worked Accord, the Mazda6’s interior is less fussy and more driver-friendly. It actually feels more upgraded compared to when it first appeared in the market three years ago. Though both of these cars have their share of hard plastics, the Mazda at least has had all its touch points improved. Anything that could be touched or controlled now has soft-touch plastics on them and being matte, they never cause unwanted glare. The new interior palette: black and brown leather with small slithers of aluminum isn’t to everyone’s liking—some found it too muted and dreary—but there’s no doubt it imparts a more Teutonic than Japanese feel. The Mazda Connect with its rotary controller is also far easier to master than the Honda’s system and the response is way snappier. Perhaps the only thing Mazda needs to work on is a new instrument cluster. Though they’re legible, it doesn’t look too differentiated from a more pedestrian Mazda3.

Winner: TIE

Space and Practicality

For potential buyers, this is probably the first and only thing they’ll look at. After all, executive sedans should be as comfortable in the back seat as it is from the driver’s, right?

This is where the Accord makes big gains over the Mazda6. Remember that top-heavy design? Well, the squared-off roofline, upright pillars, and lack of a standard sunroof create better ingress/egress and headroom. Aside from having more room for headwear and funky hairdos, there’s also more available shoulder room—something very evident between the driver and front passenger. However, the high set dashboard and low set seats do compromise the driving position a bit. Despite the wide array of adjustments plus more usable legroom upfront, it rarely feels comfortable next to Mazda’s get in and go set-up. Towards the back, the Accord shines not only because it’s got cushier seats, but because you can actually fit three adults there with enough room to spare for another kid. And for those who find themselves regularly playing golf, the Honda does have a wider, deeper, and longer cargo space. It’s only limited by the single-piece folding rear seat. In this day and age, a 60/40 split-fold mechanism should be standard.

Meanwhile, there’s no question where Mazda put the center of attention in the Mazda6. Compared to the cavernous space offered by the Accord, the Mazda6 feels “just right”—a surprise given it’s dimensionally not far off from the Honda (the Mazda even has a longer wheelbase). It doesn’t feel spectacularly spacious, but it’s not cramped either. The front allows just enough space to stretch legs or spread them apart, but get too comfortable and the padded knee bolsters will get in the way. The other parts of the driving environment from the controls, the seats, the exterior visibility—they’ve been carefully calibrated towards becoming a sharp driving tool. With that, the rear seats are certainly a downer in the Mazda. Not only does the sweeping roofline cause banged heads upon entry or exit, but the seat support isn’t that good and the space isn’t as generous. In addition, the trunk space is limited. Though a split-folding mechanism does supplement it somewhat, the Mazda6 will find it hard to swallow a week’s worth of groceries or luggage for four adults.

Winner: Honda Accord

Performance and Fuel Economy

This is easily the meat of the matter: how does it perform? How does it handle? Which is more fuel efficient? Well, the answer isn’t as straightforward as you think ever since Mazda made the gutsy move to offer the Mazda6 sedan solely with a diesel engine. That’s right, with the 2.5-liter Skyactiv-G moving exclusively to the Sports Wagon variant, this becomes an interesting case of Honda versus Mazda, diesel versus gasoline.

And like any gladiator match, there could only be one winner. In this case, it’s clearly the Mazda6. Some may decry that this match-up is a bit unfair, but consider the numbers: both have four cylinders, both have similar displacements, and both even offer 175 horsepower on tap. The big advantage of the Mazda is that it’s a diesel and as such, it has a Civic’s worth of more torque than the Accord. Lightning quick reactions in stoplight situations, locomotive-like acceleration, and power on demand are a given. But the Mazda6 is more than just a Soul Red-colored Road Runner. It’s also mighty quiet and smooth. It’s mighty efficient too—doing 10.20 km/L in the city (average speed 12 km/h) up to 25.11 km/L on the highway (average speed 86 km/h). Apart from its straight line performance, the Mazda6 also betters the Accord in the way it conducts itself through corners. It eats transition movements for breakfast, only occasionally spitting out hints of understeer. It also feels much more confident under heavy braking. On the flipside, the ride is far less cushy. It’s controlled, but firm. Jolts are largely absorbed, but tire noise is abundant at higher speed. Plus, there’s an obnoxious knocking sound from the front suspension—something that’s become commonplace with the Mazda6.

When not being pushed or carved through traffic, the Accord pretty much matches the Mazda6 in all but perhaps the less than stellar visibility. But roads aren’t made solely of EDSA and as soon as traffic clears up, the Honda begins to show its limits. Though it’s noticeably quieter, smoother, and plusher than the Mazda6, the overall feel is that of isolation. It’s numb all the way from the steering to the chassis; the pedals to the engine; the driver to the car. Don’t get it wrong, it is capable, but the car doesn’t simply communicate well to the driver. Nonetheless, the engine lets out a positive, but muted sound while the accompanying power and acceleration is brisk, especially from mid-throttle onward. The five-speed automatic, though a cog down the Mazda6 is well-suited to the engine. The steering itself is progressive and natural while the brakes still bite well. However, there’s simply no emotion attached to the entire experience. It has, for all intents and purposes, become the appliance of sporty sedans. And once you’re compared to a refrigerator, it’s not exactly a compliment. Further rubbing salt in its wounds, the Earth Dreams engine under the Accord’s hood has really affected fuel mileage which rests at a dismal 5.71 km/L (average speed 11 km/h) going up to 9.48 km/L as the speeds go up (average speed 16 km/h) topping out at 14.37 km/h on the highway (average speed 67 km/h).

Winner: Mazda6

Value for Money

With compact sedans and crossovers now offering increasingly competitive specs, there’s pressure to actually kit-up the executive sedans even more. Both these vehicles offer a substantial upgrade in terms of comfort and convenience technologies, some of which weren’t available in this price range before. That said, around P 200,000 separates the Mazda6 and the Accord with the Honda still coming out as the more affordable of the two. The question is: can Mazda justify its price difference?

When the Accord first came out in 2014, Honda played it conservatively, offering about 90 percent of equipment at 10 percent less cost than the competition. Today though, Honda has rectified this and has begun offering much more equipment at roughly the same price point. Apart from the de rigueur features such as powered leather seats, a fancy infotainment system, GPS navigation, and so forth, the new Accord does add things like cruise control and front proximity sensors to supplement the rear ones. A multi-angle parking camera is also standard on the 4-cylinder variant as well. Even the much vaulted, but equally unnecessary Lane Watch blind spot camera has been added too. It also receives a full complement of LED lighting front and back. What’re missing would be larger alloy wheels and perhaps, rain-sensing wipers. Apart from those, the Accord is looking to be a more complete package.

As good as the Accord is, its biggest problem is the Mazda6. With Mazda opting for a more simplified line-up, the Mazda6 has been kitted to the roof in terms of features; features that easily justifies its higher price tag. Adaptive LED headlights? Check. Gunmetal 19-inch alloy wheels? Check. Sunroof? Check. Powered driver’s seat with memory? Check. An 11-speaker Bose sound system? Check. Heads-up display? Check. Lane Keeping Assist? Check. Lane Departure Warning? Check. Game set and match.

Winner: Mazda6

For the executive who still longs to drive himself, it’s clear that there’s only one real choice. This matchup between the Honda Accord and Mazda6 has produced a new executive sedan king. And in this case, the Mazda6 rules the roost. Although the Accord still manages to strike a good balance between sportiness and comfort, it’s starting to veer too much already to becoming more of a chauffeur-driven car as opposed to an owner-driven one. It’s plush and luxurious, spacious and comfortable, but it’s also largely numb. In the end, it simply cannot match the fun-to-drive qualities of the Mazda6. The Mazda does trade a bit in terms of space and riding comfort for a better driving experience, but in the end, you know which one you’ll be willing drive on a long trip.

  1. Gas engine to gas engine would have been more appropriate.

    Why not the VW CC vs the Mazda6 SkyActiv-D? Big price difference but they both have diesel engine.

    1. That could be another way to look at it, yes.

      But in this case, it's two driver-centric Japanese executive sedans. It just so happens one is powered by diesel, the other gasoline.

      If it's diesel to diesel, I would go so far to pit the Peugeot 508 against the Mazda6...It's just that Peugeot is not really hot in lending me cars (because I'm just too honest haha).

    2. Same question, gas vs diesel and there's a fuel-economy category. lol

  2. Uly you've swapped the fuel economy figures on the charts :D

  3. Uly, how about pitting all gas midsize cars in a similar test? I guess you may have tested most of them (Accord, Mazda6, Camry, Sonata, Altima, Passat).

    1. Yes, I have.

      But this test was done with the sole purpose of a comparison. Both of these models weren't featured as a standalone test drive before.

      I'll mix up the regular reviews with comparison tests from time to time, but given CarGuide.PH is a one man team, it'll likely be limited to just 2 at a time.

    2. Lucky you to have test-driven all of them. I wish I could do that also. Hehehe

  4. The Honda Accord doesn't stand a chance against the might of the Mazda 6.

    1. Should've been the V6 accord vs the diesel mazda6. The mazda6 honestly is one of the best cars overall in the segment. Decent space, fun, gorgeous and fuel efficient. Its everything one wants.

    2. In a fair match-up, gas to gas version with 4 cylinders, the Accord can stand up to the Mazda6. These two have been always been on the top of list for sporty Japanese midsize cars. The Accord V6 is much quicker than the 4-bangers unless you match it against other V6-powered or turbocharged gas midsize cars.

  5. Mazda hands down. diesel engine alone kills even the v6 accord.

    1. No question of fuel efficiency figures but on performance, like on a short sprint, the torque from a turbo diesel or turbo gas engine can overwhelm the torque from a V6 NA engine. On the top end, it's a different story. The 100hp power advantage of the V6 can't be downplayed. The Accord V6 is still no slouch as it can easily accelerate from 0-100kmh in 6 seconds. If you do want ample performance from a sedan in the price range of the midsize cars, you better go with a Subaru WRX (270hp, lots of torque from its turbo four, AWD grip & handling, stiff suspension on a 4-door with a trunk).

    2. Dyan ka nagkamali iho. Mazda6 diesel 0-100km/h is only at 8.4 seconds, almost 2 seconds slower than the accord V6.

    3. Is that true? Then the Mazda6 SkyActiv diesel is just within the same 0-100kmh sprint times as its 2.5L gas brother and the Accord 2.4L and the Altima 2.5L. It might be gearing is set for fuel economy and not for sprints.

    4. They are both midsize sedans, not race cars.

    5. Yep, if you're looking for an executive sedan, why will you look for 0~100 figure? lol RICErs.

  6. diesel vs gas. the choice will only boil down to people who prefered diesel than gas, and people who are brand loyal to each brand. all other features are about the same. But this comparo is a no brainer - the Mazda6 wins hands down.

    1. There is a cheaper turbo diesel car available in the local PH market with some level of luxury similar to other midsize cars. It is a bit smaller but more like the size of older midsize cars. The Jetta 2.0L TDI is priced at 1.498M and powered by a 2.0L turbo diesel engine (140HP/320Nm).

    2. I checked out the Jetta in the PIMS, I was not impressed with the "teutonic quality" of the interior especially the interior which was full of hard plastics. I like the exterior though, it looks classy.

    3. That is a single turbo, it dies at peak. With twin-turbo, 2nd turbo will provide power at some point where the 1st one died.

  7. Hi Mr. Ang. Great comapro! Thank you for this. I've been waiting for a test of the Mazda 6 skyactiv-d for months. My most pressing concerns about the Mazda 6 are with regard to: a) durability and reliability of the diesel engine; and b) cost of maintenance beyond the 3-year free pms period. Would you be able to shed light on those two concerns? Your help would be greatly appreciated. Thank you.

    1. a) Diesel engines are more durable & reliable in general. But I'm not sure of the turbo they used on Mazda6.
      b) Check some forums, even if it is not a Mazda6 - you'll have an idea about Mazda's PMS cost.

  8. After my horrible experience with my 15' Mazda 3 HB, I'll get the Accord instead.

    1. What happened?

    2. Hi. I was the one who posted about the two concerns with the Mazda 6. Can you elaborate on your experience with your 2015 Mazda 3 HB? I'd really like to get an objective view of what I'll be facing with Mazda ownership and after sales service. Thank you.

    3. He's probably just bluffing and doesn't even own a mazda3, let alone a car. Wag ka maniwala dyan.

    4. ^I agree. It's weird that he didn't even explained the problem, then he instantly recommended the accord. I smell a honda salesman.

  9. Nung sumakay yung Lola Nya nag complain sa leg room. Hahaha. Yun naging problem Nya.

  10. i dont like the infotainment of mazda, its small , honda accord is better

    1. I don't get it why many people don't like Mazda's infotainment system, whereas BMW's and other luxury brands has the same positioning, yet no one complains about it. In my opinion, the infotainment positioning of Mazda feels upmarket than the traditional placement. I find it useful especially when navigating, wherein you do not need to look down to see where you are going.

    2. People with bmw are busy making money rather than reading reviews on jap cars.
