Summary

Mazda3

We all know that X means buried treasure in the world of children’s book pirates, but it’s looking like it could hold similar relevance for what lies under the bonnet of future Mazdas.

We first officially heard about Mazda’s industry-leading Skyactiv-X technology at the brand’s Global Tech Forum in Germany two years ago, but now we’ve ventured back to Germany to drive it in production form ahead of its Australian arrival aboard a new flagship version of the Mazda3 early next year. 

No other manufacturer has managed to productionise compression ignition for a petrol engine, and with an underlying intention to make the combustion engine work better for everyday driving, in the face of the electric-focus of all other global brands, this could be the most exciting technological development of my career.

Why invest so much in combustion engines if every other major brand is beginning to treat them like yesterday’s news? While the Japanese government predicts that 52 per cent of new cars sold in 2030 will use some form of electrification in their drivetrain, the same data suggests 90 per cent will still use an internal combustion engine as at least an element of their drivetrain. That’s 90 per cent of the market, more than a decade from now.

Honda Accord

It’s honestly a wonder we’re seeing Honda’s new Accord at all, given it enters the least favourable market conditions for sedans that Australia has ever seen.

Honda even knows it, which is why the company is bringing this new 10th-generation Accord to our market in conservatively low numbers to begin with.

In fact, the only reason we’re getting this Accord is because the Japanese brand acknowledges the sedan is part of Honda’s DNA, and that there’s a dedicated fanbase of Accord owners who won’t buy anything else.

If you’re one of those fans – pat yourself on the back – this car is just for you. So, what’s it like? We went to its Australian launch to find out.

Verdict

Mazda38.4/10

Unlike most big technological advancements, this isn’t about extra performance or reinventing the wheel, it’s about Mazda’s bigger picture approach to deliver the best mobility solutions for right now, while still planning for electric and fuel cell vehicles in the future.

That may sound like a line straight out of the Skyactiv-X press release, but Mazda’s realistic approach to our continued dependence on combustion engines is commendable. 

My final judgement will have to wait until we know how much more it will cost over a regular Mazda3, but I can say the technology works really well and should really suit Australian conditions.

Honda Accord7.6/10

Honda’s new Accord is a miracle in that it was brought here seemingly simply for fan service.

I think those fans will mostly be pleased. The 10th-generation car is high-tech, sensibly specified, safe, and certainly Honda-like behind the wheel. Just don’t expect it to be as luxurious as Japanese flagship sedans of days past.

Design

Mazda3

Aside from the stunning good looks of the new Mazda3, the only visual distinctions the Skyactiv-X version scores over a regular high-sec model are bigger exhaust tips like those seen on the latest version of the Mazda6, and a Skyactiv-X badge in place of the regular models’ Skyactiv-G. 


Honda Accord8/10

The Accord looks swish! It carries so much of Honda’s up-to-date design language through its entire body.

This majorly includes the chrome strip across the front, up-to-date LED headlights, and swoopy coupe roofline.

These are offset by a curvy line running down the rear half of the car’s profile, accented by a chrome strip. As mentioned, those wheels look bigger than they are, and add to the Accords presence by sticking way out to the edges of the chassis.

It’s referential to other vehicles in Honda’s range, like the Civic and even S660 kei-sized sports car. Fans will be happy to know the overall package is more restrained than something like the zany Civic hatch.

The cabin is almost exactly what you’d expect from a luxury Japanese sedan. This means throne-style plush leather trimmed seats (that are genuinely nice to sit in) a wide symmetrical dash look and familiar Honda touchpoints throughout.

It’s all well built and ergonomic, so there’s no complains on that front, but there are some areas where the Accord is showing its age in the design department already.

There’s a shift knob that sits too far out of the centre console (hardly a ‘high-end’ look), an odd retracting panel in the dash like its 2004, and the ‘wood trim’ that runs across the dash appears to be a plastic fill – it has no texture!

The rear seats are just as - if not more - comfortable than the fronts, and there are no complaints when it comes to packaging – the Accord's cabin is mostly a great place to be.

Practicality

Mazda3

It’s a similar story for practicality, except it’s completely identical to the regular Mazda3 this time. So expect the same decent interior packaging and convenience for four adults, with a 295L VDA boot and a space saver spare tyre under the boot floor. 


Honda Accord8/10

Speaking of packaging – it’s consistently a Honda strong point, and that’s no different in the new Accord. As already mentioned, front and rear passengers get heaps of room for their arms and legs, and there’s decent storage areas throughout.

That means two smallish cupholders and trenches in the doors, a large caddy in front of the shift-lever with that odd retracting door, and large cupholders in the centre console.

Like almost every Honda, the centre console box is colossal and hosts a single extra USB 2.0 port.

The back seat has leagues of legroom – almost limo-sized for rear passengers, although headroom is compromised a bit by the descending coupe-like roofline. The thick and low C-pillars also make getting in and out a little harder than it perhaps should be – but this is a common trait shared with other coupe-styled sedans in the class like the Peugeot 508.

Touchpoints everywhere are nice and plush, and there are only a few nasty plastics which are well hidden.

Rear seat occupants can make use of adjustable air vents, dual USB ports and a plush trimmed drop-down arm rest with two cupholders.

The arm-rest also reveals a ski port – an increasingly rare feature in today’s cars – which leads us to the boot. It’s massive at 570 litres (VDA) – that’s significantly larger than both the Camry and Liberty and the best part – it doesn’t matter whether you pick the petrol or hybrid, the boot space is the same.

Honda tells us that this is because it has managed to reduce the hybrid battery pack significantly in size – so that it can be placed under the passenger seats instead. Brilliant.

Every Accord has a space-saver spare under the boot floor.

Price and features

Mazda3

This is probably the biggest question mark above the Mazda3 Skyactiv-X’s head for now, with all we know being Mazda Australia’s plan to launch it as a new top-spec version, so sit above the existing $36,990 G25 Astina flagship. 

How far above will be the clincher, and given it’s not likely to quite match the performance of the G25, it will depend on what value you place on outright driveability and a marginal fuel saving over the base 2.0-litre engine. 

Like the rest of the Mazda3 line-up, we also expect to see the Skyactiv-X with a choice of hatch or sedan bodystyles with either manual or automatic transmissions.


Honda Accord7/10

Honda has chosen to bring the Accord in surprisingly limited numbers – just 150 units a year to begin with – and so there is just one specification level.

It’s the highest it goes though, a VTi-LX. Honda tells us there’s no chance of lesser variants, even if consumers are asking for it, so don’t hold out for an entry-spec car.

The single variant is split into two engine options. A familiar 1.5-litre petrol turbo, and a new-generation 2.0-litre naturally aspirated engine with hybrid drive.

Naturally, as a high-grade car, the price is quite high. Honda is asking $47,990 for the turbo and $50,490 for the hybrid.

This is more expensive than highly specified traditional opponents, like the segment-dominating Toyota Camry SL hybrid ($41,090) and Subaru Liberty 2.5i Premium ($37,940). You could also consider cross shopping it against something like Peugeot’s new 508 GT ($53,990) – but if you’re an Accord fan there’s a good chance none of those alternatives matter.

Standard spec is great. The Accord sports the best of Honda’s catalogue and then some. Standard are flashy 18-inch alloys that look big in the Accord’s wheel arches, an 8.0-inch multimedia touchscreen with Apple CarPlay and Android Auto as well as marginally better software suite than the rest of Honda’s range (typically a sore point for Honda). Unlike pretty much every other Honda though, the Accord scores a 6.0-inch head-up display and one of its dual dials in the dash is digital, and configurable to several layouts including navigation.

You’ll also be getting a wireless phone charging bay, but no USB-C. At least it gets Apple CarPlay and Android auto from the get-go, unlike the current Camry which will need to have it retrofitted if you bought one prior to it being rolled out.

The Accord has an electronic parking brake, auto parking function and active cruise control to sweeten the deal, too. More on safety features later in this review.

Engine & trans

Mazda3

What’s compression ignition again? It’s basically how a diesel engine works, by using extreme pressure instead of spark plugs to burn fuel. Skyactiv-X still uses spark plugs, but only to kick off the ignition process and act as a safety net for cold starts and other edge cases, while extreme compression makes for much more effective combustion, which means improved efficiency. 

This combustion efficiency means the engine can use a much leaner fuel-to-air mixture, and make more power and torque with less fuel and even less wasted fuel out the exhaust. Mazda describes it as delivering diesel-like torque and fuel consumption, with the power, responsiveness and refinement of a petrol. Or in other words, one step away from turning water into wine... 

Mazda is calling the process Spark Controlled Compression Ignition (SPCCI), and the extreme pressures required to make it all happen are created by higher static compression ratio (but less than a typical diesel), much higher fuel pressure and boosted air pressure entering the combustion chamber. 

Key to managing all these heightened parameters (and the very technological advancement that makes it all possible) is an ultra sensitive in-cylinder pressure sensor that has been developed specifically for this task. 

Delivering the boosted air pressure is a Roots-type supercharger - or what Mazda describes as a high-response air supply - which was chosen over other air pump designs like a turbocharger or the Miller-cycle supercharger previously used in Eunos models because of its instantaneous boost delivery and breadth of efficiency.

Speaking of breadth of efficiency, perhaps the biggest plus for average motorists is that the engine’s efficiency zone has multiplied, meaning the difference between city and highway consumption, leadfoot drivers and my Dad, heavy and empty loads etc will be far less than a typical petrol engine.

This all represents a continuation of core principles we’ve seen from the start of Mazda’s Skyactiv era. That is, to make an existing engine type work better under everyday driving conditions rather than targeting outright performance.

The Skyactiv-X era starts with a 2.0-litre based on the regular Skyactiv-G engine, with the same 1998cc capacity. Other capacities are planned, with the eventual reborn rotary looking increasingly Skyactiv-X along with a straight-six version for a new CX-9 in a couple of years. Smaller versions are unlikely due to the economies of scale involved with such technology in a smaller and therefore cheaper car. 

Mazda is making two versions of the Skyactiv-X 2.0-litre for now, one with 16.3:1 compression designed for Europe that favours Premium unleaded petrol, and one 15:1 version aimed at the US with their abundance of lower grade unleaded. 

Unlike conventional engines, it’s the lower compression version that will deliver the biggest benefits, because Skyactiv-X relies on the usually “bad thing” pinging to do its best. 

We’re set to get the Euro-spec one in Australia, which unfortunately means we won’t quite be getting the very best Skyactiv tech again.

The Euro-spec engine puts out 132kW at 6000rpm and 224Nm from just 3000rpm, which on paper sounds about halfway between the existing Skyactiv-G 114kW/200Nm 2.0-litre and 139kW/252Nm 2.5-litre petrol engines.

The engine also incorporates a mild hybrid system, but don't be confused by the H-word, there's no electric drive element. It simply means its got a cleaver alternator that only engages when needed and on deceleration to reduce efficiency-sapping drivetrain friction,

Pop the bonnet and you’re confronted by the biggest engine cover you’ve ever seen, but unlike most, this one is equipped with labeled latches that encourage you to have a look underneath. This encouragement continues with a clever little retention hook to hold the cover up against the bonnet while you’re poking around.

Unless you’re a Mazda engineer you’re likely to be baffled by the array of hoses, ducts and wiring, but you might get a kick out of spotting the supercharger.

There’s less to be said for the transmissions though, with versions of the existing six speed manual and torque converter automatics deemed up to the task, with the new engine’s increased efficiency zone negating any increase to the ratio count. The ratios have been adjusted to suit the new output characteristics, and while the ratios are yet to be published, there’s a narrower spread across the six with what feels to be taller first and sixth gears.


Honda Accord7/10

The Accord will only get two engine options – the first is a 1.5-litre turbocharged four-cylinder engine which will be familiar from other Hondas where the same engine lives. Honda says it’s put a new head on for the Accord and tightened up the engine’s response. The result is the same 140kW power output, but an increase in torque to 260Nm. This engine is mated exclusively to a stepped-ratio continuously variable transmission (CVT).

The other option is a 2.0-litre naturally aspirated petrol four-cylinder with hybrid drive. Combined system output is 158kW/315Nm, so it is the more powerful of the two choices.

It also has a different transmission which Honda refers to as the e-CVT – but it proved to behave quite differently as explained in the driving section of this review.

All Accords are front-wheel drive.

Fuel consumption

Mazda3

All this hooha about fuel savings, and Mazda is yet to confirm an actual figure for Australia. We do know the hatch is rated at 4.5L/100km in manual and 5.3L/100km in auto according to the NEDC, which is historically close to the figures generated by the ADR 81/02 test we go by in Australia. 

If it comes close to matching the NEDC figure it will be a win, sitting comfortably under the 6.4L/100km (manual) and 6.2L/100km (auto) figures currently applied to the Skyactiv-G 2.0-litre Mazda3 hatch

While the Australian-spec Skyactiv-X engine is expected to align with Europe rather than the US, and therefore be tuned to deal with Premium 95 RON unleaded, it’s still unclear if it will accept the cheaper Regular 91 RON unleaded.


Honda Accord8/10

The Accord has brave claimed/combined fuel usage figures of 6.5L/100km for the petrol-turbo and 4.3L/100km for the hybrid. If real-world tests can even come within a litre or two it will prove to be fantastic for the segment – but you’ll have to wait until we get one for a week-long road test for a fair real-world figure.

Honda says its engines are tuned to run on 91RON unleaded petrol, and the Accord has a 56-litre fuel tank in the turbo or 48.5L in the hybrid.

Driving

Mazda3

What’s probably most amazing about Skyactiv-X is that you can’t really tell there’s anything special going on under the bonnet. 

Push the start button and it gets going like any other petrol Mazda, although perhaps quieter. 

Move off from rest and there’s no significant difference to the way it feels. 

When I drove the prototype version of this drivetrain, there was a slight pinging under light throttle as it transitioned from spark to compression ignition, but I’m pleased to confirm that the extra two years of calibration has tuned this down to the tiniest occasional diesel sound, and it all feels a bit like a smooth diesel that’s more responsive than you expect.

The European-spec Skyactiv-X 2.0-litre’s outputs suggest it should be closer to the existing 2.5-litre in terms of performance, but in reality it feels closer to the 2.0 litre.

My perception is likely to be clouded by the Skyactiv-X’s specific transmission gearing, but it could also be because it’s able to do the same job with less revs and therefore not sound like it’s working so hard. 

First gear feels quite tall with either transmission, and we also found the auto and manual were only sitting on 3500rpm in sixth at 160km/h on the Autobahn. 

Mazda doesn’t specify performance figures, so it would be handy to put all three alongside each other from a standing start. But then, that’s not what Skyactiv-X is all about, it’s more about performing better under light throttle and incidental bursts of acceleration. 

We can’t wait to put it to the test over some hilly terrain and familiar territory when it hits Australia early next year.


Honda Accord7/10

The Accord doesn’t quite drive like you might expect. It betrays its luxurious look and plush interior with a firm ride.

Honda says this is because it has imbued the “spirit of Accord Euro” into the development process for this new Accord – suggesting that it can appeal as much to fans of the sporty Accords of days past as much as it does for its Japanese luxury car fans.

I think they’ve gone overboard, though. The chassis and dampers are stiff. Too stiff. This car feels abrupt and crashy over larger bumps, and unsettled over smaller ones.

The flip side of that, of course, is that it is a blast to throw into corners. With the wheels way out to the edges of the chassis (the Accord is wider than ever) it simply refused to understeer, giving it handling prowess that eludes most front-drive sedans this size.

In some ways its like driving a giant Civic, and for those who enjoy driving, that will be a very good thing.

Both engine options don’t quite keep up with the abilities of the chassis. While the 1.5-litre petrol punches above its weight when it comes to power, it’s just not an athletic performer, especially when you’re demanding straight-line acceleration.

Its weak link is largely the transmission which tries to emulate a torque converter by stepping its way through 'ratios'. It has some typically negative characteristics of limiting the feedback, and changing the ratio at seemingly random times.

The hybrid is better, both on power and in terms of its transmission, which locks up when needed. It’s still no true performer though.

Neither option seems to be capable of spinning the front wheels, either through lack of power or design, so if nothing else, it’s predictable and feels safe.

Handling proved to be good, with Honda’s direct and fast steering being on-point, and the signature chunky leather-bound wheel offering a satisfying way to interact with the car. The steering does have a slight artificial tinge to it, especially with the seemingly computer-weighted ‘Sport’ mode, but Honda has also reduced the turns lock-to-lock, making it fast to park in city scenarios.

I was surprised to find that road noise in both variants wasn’t great. It’s better than in the Civic, but Honda claims it has gone to lengths to deaden it, so I had hoped it would be quieter inside. The engine noise is better – relegated to a distant hum unless you’re really wringing it.

Overall, it’s a good – if a little firm – driving experience. It just doesn’t quite live up to the luxury promise set out.

Safety

Mazda3

The existing Mazda3’s maximum five-star ANCAP safety rating will almost certainly be carried over, and the high level of safety gear fitted to the existing G25 Astina is also likely to be matched. 

This means front and rear airbag coverage, front and rear AEB, front and rear cross-traffic alerts, lane keeping assistance and blind-spot monitoring


Honda Accord8/10

The Accord impresses with a fairly comprehensive standard safety suite, helped along by the fact that the brand only needs to bring one variant to market.

On the active safety front, it gets auto emergency braking (AEB – with pedestrian detection), lane departure warning with lane keep assist, adaptive cruise control, driver attention alert, and Honda’s strange Lane Watch camera suite in place of blind-spot monitoring.

It also gets an expanded suite of cameras with a wide angle top-view to assist with parking.

On the expected front, the Accord gets the standard suite of stability, brake, and traction controls as well as front and side curtain airbags which have ‘safety vents’ to prevent airbag injury and ‘roll-over sensors’ which can keep the airbags deployed for longer in the case of a prolonged rollover scenario.

The Accord has not yet been rated by ANCAP.

Ownership

Mazda3

Service pricing is also yet to be confirmed, but Mazda engine development boss Eiji Nakai assures CarsGuide that the new engine will not need servicing more frequently or cost any more to service than existing Skyactiv-G engines.  

So expect the same 12month/10,000km intervals, with five year/50,000km capped servicing plan totalling just under $2000 over that period.  

Like all new Mazdas, the recently upgraded five-year, unlimited kilometre warranty will apply to the 3 Skyactiv-X. 


Honda Accord8/10

Honda covers the new Accord with its five-year/unlimited kilometre warranty promise – which is competitive against both the Camry and the Liberty as well as other mainstream brands.

The Accord requires servicing once every 12 months or 10,000km whichever occurs first or when the engine computer tells you.

While you might be at the mercy of the computer, services are capped all the way out to 10 years/100,000km at just $312 a visit. That’s mega cheap.

There are a few things not covered under the “base service price” but they shouldn’t throw up too many red flags. The most expensive is the ‘HCF – 2 fluid’ every three years at a cost of $172, or the spark plugs every 100,000km at a cost of $289.
