Summary

Toyota Prius

Tree-huggers get a bad rap, especially when they're accused of driving Priuses, a particularly targeted form of abuse inspired by the Malibu movie set. Hollywood types who stepped out of gas-guzzling private jets to tool around humbly in Toyota's trailblazing hybrid used to include dapper chaps like Clooney, Damon and di Caprio.

They must have been pleased when Tesla arrived with bigger, faster, fully electric cars. Sometimes you really need to get to your private jet in a hurry.

And I say they were pleased because driving a Prius forced these folks to consider what life would have been like had they not played that dead body on CSI, before rising through the ranks to owning chunks of a coffee-pod company and marrying lawyers who make speeches at the UN.

The Prius was a run-of-the-mill car that appealed to them only via its new hybrid technology, whicht helped assuage their guilt at burning several tonnes of avgas instead of mixing it with the general public on commercial airlines.

In 2019, Toyota has four hybrids (including a RAV4) with which to attract your attention, and one of those is the 20-year-old Prius. Still odd-looking, still a hybrid, still pretty much the same proposition as that first, nose-diving sedan all those years ago. Its own bretheren are out to consign it to irrelevance. Or is it still worth another look?

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.

Verdict

Toyota Prius 7.1/10

In 2019, the Prius is a head scratcher. Toyota has the hybrid Corolla on the same TNGA platform but it's a better overall proposition, cheaper and vastly better looking. If you can find one, you can have a hybrid Camry for a similar money. 

Committed EV buyers can now buy a fully electric Hyundai Ioniq for a few bucks more. It almost feels like the Prius is hanging on for the fans so it rather has the feeling of an Eagles concert... without the hits.

It's difficult to see why you wouldn't save a significant amount of money and go for a Corolla Hybrid. The ZR I drove last year was $13,000 cheaper than the Prius, and a far more satisfying drive.

With cheaper Korean options hoving into view - and Toyota's own Corolla - is the Prius' day done?


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.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.

Design

Toyota Prius

My goodness this is an awkward-looking car. The Prius set the template almost two decades ago and it seemed like any hybrid, no matter where it was from, looked like Toyota's pioneer for a while.

Part of the awkwardness is a result of wind-tunnel styling to maximise the benefit of the hybrid power unit - that high, boxed-off tail makes the Prius slippery, but weird looking. The adventurous shapes of the lights front and rear really don't work (for me, anyway). The tiddly wheels amplify the slabbiness of the sides.

I say tiddly because, as you know, they're just 17-inchers. The base model Prius has a laughable set of 15s bolted on.

You know, just by looking, that this is a Prius and, by extension, a hybrid.

The interior is a bit more contemporary, but littered with cheap Toyota staples like that dodgy LCD clock that used to be in my Mum's Echo. Speaking of the Echo, Toyota has recycled and expanded on the idea of a centrally placed dashboard, all of which is digital but without the inventiveness of a German, or even a Korean car. It works really well, to be fair, but there's not much in it to amuse or delight.

The central touchscreen is nice and close and shows additional information about the hybrid-drive system. The profusion of piano black is a bit passe, though, and picks up dust and fingerprints.


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. 

Practicality

Toyota Prius

Passenger space in the Prius is excellent for its footprint. Slightly roomier than the Corolla, front and rear passengers have generous head and legroom, although the narrowing hips pinch the shoulders a bit with five aboard. The roofline also abbreviates headroom for anyone over about six feet. The seats are comfortable, though.

Front and rear rows are each treated to two cupholders and bottle holders, for a total of four of each. The front centre console also has a Qi wireless charging pad, as well as a deep bin under the armrest.

Boot space starts at a modest 343 litres to the parcel shelf but if you drop the rear seats, you've got a very generous 1633 litres. The lower-spec Prius has a much smaller boot (297 litres) but does have a spare tyre.

Toyota hasn't certified the Prius with a towing figure.


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. 

Price and features

Toyota Prius

The 2019 Prius update is available in two specs - entry level for $36,590 and this i-Tech for a stout $44,050. For that outlay you score 17-inch alloys, a 10-speaker JBL-branded stereo, keyless entry and start, Qi wireless charging pad, auto LED headlights, auto wipers, reversing camera, electric everything (except the tailgate), fake leather trim, climate control, head-up display, sat nav and a tyre-repair kit.

Toyota's worse-than-the-final-season-of-Game-of-Thrones multimedia system soliders on. It's hard to use, terrible to look at and, even with the Kluger-style shortcut buttons, leaves me screaming, alternately, for a hug and for Apple CarPlay/Android Auto.

There's just no excuse for a system this bad in the modern world. Toyota Australia's stubborness is admirable, in a way. The sound is really good, though, and it comes with DAB, which is fine if you can work out how to find the station you want in the confusing user interface.


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.

Engine & trans

Toyota Prius

The 1.8-litre four-cylinder engine produces 72kW and 142Nm. Due to the vagaries of hybrid-power calculations, the combined power output is 90kW, but there is no combined torque figure. It's unlikely - given the 1400kg kerb weight - that it's only 142Nm.

Along with the Atkinson-cycle internal-combustion engine, the Prius has two electric motors - one acting as a generator and one to drive the front wheels via a continuously variable transmission.


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.

Fuel consumption

Toyota Prius

Official figures are always worth a chuckle, but the combined-cycle figure for a hybrid is always an interesting pointer. In the Prius, the ADR figure is 3.4L/100km. My week with the Prius in almost exclusively city driving - its natural habitat - yielded an impressive 4.3L/100km.


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.

Driving

Toyota Prius

Despite rolling on Toyota's TNGA platform, it's not a particularly interesting car to drive. As with the old Prius, there's a fair bit of body roll and not a small amount of dive under heavier braking.

Neither of these are likely to trouble you, as the underpowered nature of the Prius enforces a relaxed pace, much like the hybrid Corolla I drove last year.

The uninspiring combination of modest power outputs and a CVT transmission is a Toyota staple and never fails to set my teeth on edge.

Having said that, the Prius is very quiet and an easy place to spend the commute. Again, the target buyer isn't looking for an excitement machine - fast hybrids are vastly more expensive - this car smashes its KPIs.

Toyota's early progress has been engulfed by its competitors, however. The Prius has all the clicks and whirrs but it's still essentially the same car it always has been - press the accelerator a bit, you get a few metres of near-silent progress, then the engine kicks into life and off you go.

The whacky joystick gear selector features D position and B. Other hybrids and BEVs have what I thought was a similar feature, a separate mode to increase the aggression of the energy harvesting from braking. Not the Prius - B means braking, which you can use on a long downhill run to reduce the strain on the tiny brakes. Switching to B mode induces engine braking by lowering the gear ratio in the CVT.

And, on that point, the Prius pretty much drives like a normal car. Some hybrids use the drag of the generator to assist with braking and therefore charge the battery, but the Toyota is almost entirely conventional-feeling.


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.

Safety

Toyota Prius

The Prius i-Tech ships with seven airbags (including driver's knee bag), ABS, stability and traction controls, reversing camera, blind-spot monitor, rear cross traffic alert, lane-departure warning, forward-collision warning and forward AEB.

For the kiddies, there are three top-tether anchor points and two ISOFIX points.

The current Prius scored five ANCAP stars in October 2016.


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

Ownership

Toyota Prius

Toyota has joined its rivals in the long-warranty camp, now offering five years/unlimited kilometres on its whole range. Roadside assist is an extra cost, though. 

Your Prius' service costs are capped for the first three years/60,000km and you have to take it back to Toyota every six months/10,000km. Thankfully, the services only cost $140 a pop.


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.
