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.
Really small cars aren't what they used to be, and there are a number of reasons for that. The first is that, compared to five years ago, nobody buys them. The world of small hatchbacks is a shadow of its former self, mostly because there's so much money sloshing around in Australia that we buy a class up and often an SUV rather hatch.
As usual, Citroen is taking the path less travelled. There's no getting away from the fact that the C3 hatch has always been an a brave choice - there are still a few of the original, arch-roofed version kicking around, a car I was very fond of, despite it not being very good.
For 2019 Citroen has addressed a couple of glaring issues with the C3, namely a lack of safety gear that contributed to a four-star ANCAP safety rating and a couple of little dramas that marred an otherwise impressive package.
|Engine Type||1.2L turbo|
|Fuel Type||Regular Unleaded Petrol|
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.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.
As you've probably gathered, the C3 is a fun little car with a proper personality. Obviously it's not cheap - Japanese, German and Korean competition are all cheaper - but none of them are as individual as the C3.
And that's probably its strength and weakness. The looks are polarising - you'll spend your entire time with the car explaining the Airbumps to perplexed onlookers. The updated safety package is a huge help to making the C3 more comeptitive at a specification level, but the price of entry is still high - Citroen knows its market.
Would I have one? Definitely, and I'd love to try one in manual, too.
Would you consider a C3 now that it's got better safety gear? Or is that whacky exterior too much for you?
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.
Little has changed in the looks department, and that's a good thing. While the C3 isn't to everybody's taste, it's certainly a Citroen. The car has drawn heavily from the bold-as-brass Cactus, which I genuinely think is one of the greatest pieces of automotive design, certainly for a mass-produced car. Funky and, as it turns out, quite influential - have a look at the Kona and Santa Fe. The only real differences are colour-coded door handles with chrome strips.
All present and correct are the rubber Airbumps down the lower portion of the doors, the stacked headlight and DRL arrangement that is the "wrong" way around. It's chunky and very much aimed at the compact SUV crowd.
The cabin is basically the same and still terrific. Again, lots of Cactus in here, which includes the two of the best front seats in the business. The dash design is a cool departure from the rest of the planet, with lots of round-edged rectangles and a consistency of design across the Cactus and other Citroens. The materials are mostly pretty good, but the central console is a bit awkward-looking and sparse.
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.
The weird French approach to cupholders lingers with the C3. Perhaps to match the name, there are three - two in the front and one in the back at the rear of the centre console. Each door will hold a mid-size bottle for a total of four.
Rear-seat room is acceptable, with good knee room for adults up to 180cm. I toured around in the back and was perfectly happy behind my lanky son's front-seat lounging position. Headroom is very good front and rear as it's quite upright.
The boot isn't bad for a car this size, starting at 300 litres with the seats in place and 922 litres with the seats folded down. There is quite a step in the floor with the seats down. The floor is also not level with the loading lip, but it does liberate a few litres, so it's not a huge deal.
Price and features
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.
Prospective C3 buyers will have to endure a solid price rise on the old car, which landed just over a year ago at $23,480 before on-roads. The 2019 car lists at $26,990 but does come with an overall uplift in spec.
As you did previously, you get cloth trim, reversing camera, auto headlights and wipers, leather steering wheel, trip computer, climate control, rear parking sensors, cruise control, power windows all around, speed-limit recognition and a space-saver spare.
The 7.0-inch touchscreen carries over unchanged and includes Apple CarPlay and Android Auto. These are welcome additions, although the basic software is okay on its own. Like other Citroens and sister Peugeots, the screen hosts much of the car's functionality, which makes sorting out the air-con a bit of a memory game.
Engine & trans
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.
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.
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.
Three things work together to make the C3 (see what I did there?) an excellent small car.
The first is the brilliant 1.2-litre turbo triple cylinder. This is such a terrific engine. It's not the quietest or the smoothest, but once you've got things spinning, it's torquey and keeps you rolling very nicely indeed.
In my previous outings in the C3, I've noticed a propensity for the transmission to engage a little too enthusiastically, particularly after waking from stop-start. It now seems to have had a little calibration update that has smoothed things out remarkably. It honestly doesn't feel as slow as its 0-100km/h figure suggests.
Secondly, it's incredibly comfortable for a small car. Even at launch, riding on 17-inch wheels I was impressed, but now on 16-inch wheels with higher-profile tyres, it's even more relaxed. The C3 is no corner-hugging handler, with a bit of body roll and a comfort-biased spring and damper setting, but it's not an understeering duffer, either. Only sharp tranverse bumps upset the rear (nasty rubber shopping centre speed bumps, I'm looking at you) and most of time it feels like a much larger and generously-sprung car.
These two form the basis of a package that seems equally at home in the city and out on the freeway. It's quite something.
Third, it neatly straddles the line between compact SUV and small hatch. Accepted wisdom would suggest sticking to one lane, but the successful blurring of the lines means that you get much of the visual and practical elements of that class while also not paying for, say, the C3 Aircross, which is an out-and-out compact SUV. It's a weird marketing play, but the "What's that?" chats in the shopping centre car parks weren't of the heated kind.
Obviously, it's not perfect. It's reasonably sluggish once you're past about 60km/h and grip is at a premium. The cruise control still needs way too much attention to activate and the touchscreen has too many functions crammeed in, as well as being a bit slow. The lack of AM radio is fixed by the addition of DAB.
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.
There are also three top-tether restraints along with two ISOFIX points in the rear.
ANCAP awarded just four stars to the C3 in November 2017 and at the car's launch, the company expressed its frustation at the low score, which it believed was a result of the lack of AEB.
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.
Citroen provides a five-year/unlimited-kilometre warranty as well as five years of roadside assist. Your dealer expects a visit every 12 months or 15,000km.
Service pricing is capped as part of Citroen's Confidence program. You'll be confident of paying a fair bit, though. Servicing starts at $381 for the first service, climbing to $621 for the third and moving around until the fifth year.
