Mazda 3 vs Toyota Corolla

What's the difference?

Given how effortlessly it traverses the mainstream and premium small car classes, the Mazda 3 might be the best value small car on the planet.

With racy styling, sports car handling, classy interior presentation and impressive, intelligent efficiency, there’s plenty to sink your teeth into here.

Poor rear vision, a dark back-seat area and smallish boot aside, it doesn’t have any glaring faults.

In a world overrun with SUVs, props to Mazda for evolving the small car so brilliantly to mask a half-decade of existence. Continuous improvements have made the 2024 G25 Evolve SP Vision an essential small car shortlist proposition, regardless of price.

After several years in market, the Toyota Corolla Ascent Sport Hybrid stands up well. Late 2022 upgrades have helped keep the hybrid powertrain on the pace and the multimedia system competitive. The sedan layout is better than the hatch for carrying people and cargo, it’s a refined and comfortable drive, and the ownership package sets the pace in this category. That said, safety is good but could be better, the CVT’s a bit drony, there are some small things we’d like to see on the standard equipment list (adjustable rear ventilation, extra USBs) and there’s room for improvement in terms of in-cabin storage. But overall, it’s hard to go past this small sedan proposition.

How is it that the current Mazda 3 is already five years old? This hatchback is still stunning, the sort of car you look back at when walking away.

The shape is sleek and almost coupe-like, with a shark-like nose, cab-backward-style long bonnet, upswept shoulder line and a fastback silhouette.

More importantly, it’s the way the light dances across the sculptured sides that draw the eyes in. Bereft of clutter, it makes you wish all mainstream manufacturers had the courage to be so daring.

We’ve said it before – the 'BP'-generation Mazda 3 (Axela in Japan) is the brand’s boldest C-segment hatch since the 1993 'BA' 323 (Astina/Lantis/323F).

But there’s a price to pay for such timeless beauty…

The current Corolla sedan arrived in late 2019, a bit over a year after the hatch, and the car’s dramatic face with long angular headlights and huge lower grille has held up well.

Always a subjective call, but I think it still looks fresh and distinctive, in the case of the sedan, balanced by a less complex rear treatment, no doubt applied with a four-door buyer’s typically more conservative tastes in mind.

Worth noting for an entry-grade model our Ascent Sport looked particularly classy in ‘Atomic Rush’, a sedan-only body colour, and overall the car’s ‘three-box’ proportions are well balanced, helped by the base car’s step up from 15- to 16-inch alloy wheels in the 2022 upgrade.

The interior is simple without crossing over into plain, the dual-level dash design accommodating an 8.0-inch media screen standing proud in the centre, and a compact instrument binnacle sitting under a curved brow.

The grey fabric seat trim looks tough but doesn’t feel it, with some squiggly quasi-quilting in the centre panels adding visual interest. The only other hint of flashiness being gloss black finish panels in the centre console, around the ventilation controls and media screen.

There is a price to pay for all this quasi-coupe styling flair, and that’s a comparatively snug-feeling interior, though you’d never call it cramped.

Actually, the Mazda 3 is no less spacious than most of its competition in all but one area, with enough room even for 200cm drivers, along with sufficient shoulder width and ceiling height to match.

If you’re really tall, maybe that missing sunroof isn’t such a bad thing, after all.

Sat so low-down on cushy, enveloping front seats that offer plenty of comfort and support, this is the anti-SUV. Maybe Mazda should have called this the MX-3.

Sporty and spot-on, the driving position is a laid-back affair, with an emphasis on better ergonomics, as emphasised by the thoughtful placement of switchgear that’s all within easy reach, ahead of a beautifully flowing and layered dash. Proudly Japanese in flavour, it brings to mind functional minimalism.

Drilling into some of the 3’s finer interior details, the analogue-look digital instrumentation is super-legible, ultra-classy and gorgeously lit at night. As previously mentioned, the dials and surrounding air vents are reminiscent of the later Porsche 944 and 968.

It’s not just all for the sake of aesthetics, either.

Yes, it’s lovely, but the thinned-rim three-spoke steering wheel feels great to grip, with nifty little paddle shifters that are a delight to prod.

Same goes for the physical volume knob and climate-control buttons, sidestepping the need to get distracted and frustrated by virtual sub-menus.

And having a conventional gear lever with old-school Tiptronic-style shifts suits the 3’s athletic vibe.

Plus, forward vision is A-OK, ventilation is faultless, storage is better than you might expect, and the fit and finish is as good if not better than any of this 3’s German premium opponents.

Out back, the split-fold rear backrest is set at a comfortable angle, the cushion is well padded, and you’re provided with USB ports, air vents, and an armrest with two cupholders. More thoughtfulness.

But while knee room is fair, rear headroom isn’t great if you’re tall or wear a beehive, as the falling ceiling line reveals.

Vision out is limited by that rising window line and fat pillars. Getting in and out of the back requires some contortionist moves. And the small windows mean it can be gloomier in the back than a Smiths album.

Finally, at just 295 litres, the 3’s cargo capacity is disappointing. Sure, it eclipses the Corolla hatch’s 217L cubby, but other rivals are far larger back there.

At least the floor is wide and flat and there are 60/40-split backrests for cabin access for longer items.

Note that a space-saver spare wheel lurks underneath. Mazda argues there’s always the closely-related CX-30 if you need (slightly) more space (317L).

Meanwhile, at the other end of the 3…

At just over 4.6m long, close to 1.8m wide and a fraction over 1.4m tall, the Corolla sedan is a ‘big’ small car. And at 2700mm, the sedan’s wheelbase is 60mm longer than its hatch equivalent.

There’s plenty of breathing space up front and storage runs to generous door bins with space for large bottles, two cupholders in the centre console, a lidded box (which doubles as a centre armrest) between the seats, a decent glove box and the wireless charging tray in front of the gearshift. That’s all fine, but some extra oddments space in the centre console would be nice.

Move to the rear and the sedan’s extra wheelbase length manifests itself in the shape of noticeably more room than the hatch.

In fact, power and connectivity options number just two; a USB-C socket in the front for charging and media connection as well as a 12V outlet in the front centre storage box. 

Modest boot space is an Achilles Heel for the Corolla hatch, but the sedan’s 470 litres of cargo volume is way better.

It swallowed our three-piece luggage set or the bulky CarsGuide pram with room to spare, and the 60/40 split-folding rear seat lowers to liberate extra space. Just bear in mind that the relatively tight aperture is a large-load disadvantage relative to a wide-opening hatch door.

Interestingly, there aren’t any tie-down anchors in the boot to secure loads, but there’s a space-saver spare under the floor.

Also worth noting the Corolla Hybrid a no-tow zone. If you need to hook up a boat or campervan, the 2.0-litre non-hybrid Corolla sedan is rated for a 1300kg braked trailer (450kg unbraked).

As mentioned, small sedans aren’t exactly thick on the ground in the Aussie new-car market, but there are three similarly-sized four-doors in close range to this Corolla Ascent Sport Hybrid’s $32,110 (before on-road costs) asking price.

Namely the Kia Cerato Sport+ ($31,440), Mazda 3 G20 Pure Vision ($32,320) and Subaru Impreza 2.0i-S ($32,590).

There’s also climate control air (single-zone), a 7.0-inch information display in the instrument cluster, keyless entry and start, wireless phone charging, active cruise control, an electro-chromatic rear view mirror, 16-inch alloy wheels, LED headlights, tail-lights and DRLs as well heated door mirrors.

The seat trim is fabric and for things like rain-sensing wipers, side and rear privacy glass, as well as a ‘Premium’ steering wheel, you’ll need to step up the SX Hybrid Sedan at $33,780. But the Ascent Sport lines up well relative to its direct competitors.

When you think about it, shoehorning a big torquey engine in a light and agile small car is a recipe for fun. Ford did just that with the Escort RS2000 in the 1970s… and Mazda’s now an expert at it, too.

The engine in question is the G25, a 2.5-litre four-cylinder naturally aspirated twin-cam petrol engine, delivering 139kW of power at 6000rpm and 252Nm of torque at 4000rpm.

As this Evolve SP Vision hatch tips the scales at 1415kg, it makes for a healthy, and consequently very lively, power-to-weight ratio of over 98kW/tonne.

That’s if you decide to use all the available revs, which the six-speed torque-converter auto makes great use of.

Driving the front wheels, it offers a 'Sport' mode to extend the revs even more, which is keeping in line with this Mazda’s sporty character.

Less so is the company’s decision to ditch the old multi-link independent rear suspension system a few years back for a more prosaic torsion beam arrangement. We’ll get to how that affects ride and handling in a moment.

The Corolla hybrid is powered primarily by a naturally aspirated 1.8-litre four-cylinder petrol engine operating on the ‘Atkinson Cycle’, which adjusts cam timing to maximise the effective cylinder expansion ratio (compression stroke vs power stroke) for greater efficiency and reduced emissions.

But the downside of this combustion cycle is a relative lack of power, which is where the car’s primary AC synchronous, permanent magnet electric motor comes into play.

Upgraded in late 2022, the motor now features double the number of magnets (per pole) inside the rotor.

At the same time a lighter lithium-ion battery was added, featuring greater input and output power compared to the nickel-metal hydride unit it replaced.

A compact starter/generator (effectively a second electric motor) is powered by the engine (it also starts it) in turn sending energy to the main drive motor and battery. 

The end result is combined outputs of 103kW (+13kW) at 5200rpm and 142Nm at 3600rpm, although it’s worth noting Toyota has a strange habit of not including the torque output from the electric motors in its overall numbers for hybrid models.

With the primary motor alone producing more than 160Nm of pulling power, you’d have to imagine the actual combined torque figure is somewhere in the region of 250Nm, with drive going to the front wheels via a CVT auto.

Mazda claims the G25 averages 6.6L/100km on the combined cycle… for a carbon-dioxide emissions rating of 154g/km. On a 51L tank, that gives a potential distance of over 940km!

Driven good and hard in our hands, we managed 7.5L/100km, which isn’t bad given the speed and conditions it was subjected to.

Plus, the Mazda’s happy on 91 RON 'standard' unleaded petrol.

Toyota’s official combined cycle fuel economy number for the Corolla’s hybrid powertrain is 3.9L/100km, the 1.8-litre engine emitting 81g/km of CO2 in the process.

That’s up slightly from the pre-upgrade model’s 3.5L/100km claim, but over a week with the Ascent Sport we covered around 250km of urban, B-road and some freeway running, returning an average of precisely 3.9L/100km (at the bowser), which is an outstanding result for a close to 1.4-tonne four-door sedan.

Of course, the super smooth stop-start system (controlled by the starter/generator) plays a part, plus the bonus is the 1.8-litre four is happy to accept ‘standard’ 91 RON unleaded, and the fuel tank holds 43 litres, which translates to a range of just over 1100km. Pretty great.

Ask yourself. What do you want from a new small car?

Since the first Familia of the early 1960s, Mazda’s been at it constantly, through the 1300 and 323 eras and into the modern age of the 3.

The Hiroshima brand knows its stuff. Space, practicality, comfort, ease, reliability and affordability. But a small car has to offer more, specifically in the way it makes the owner feel.

That’s why, while the Focuses, Lancers, Astras and Pulsars are gone, the 3’s still here. And it isn’t just the lush visuals inside and out that are, well, sensory-rich.

As older Alfa Romeo owners know, there’s something special about an engine that sounds alive, and the moment you push the 3’s starter, it purrs into life. That’s the first clue.

Slot the refreshingly old-school lever into Drive, and the G25 leaps into action, and, if you need it to, will keep pulling forward strongly, engine buzzing, like it’s on a mission.

There is a consistent and unifying control to the 3’s linear and forgiving dynamics, reminiscent of past masters like the Focus (and today’s brilliant Peugeot 308) that makes it a joy to drive enthusiastically through fast corners, with the knowledge that it won’t suddenly snap-oversteer and bite an unalert driver back.

For a Mazda, the ride is quiet enough, but there is still some droning transmitted through the cabin, via the Bridgestone Turanza (215/45) tyres, on coarse-chip bitumen surfaces.

And while suspension comfort is pretty impressive for the most part, larger bumps reveal the torsion beam’s limitations, as the car can occasionally thud over them in a way that we remember the multi-link rear end wouldn’t.

Anyway, what we’re saying is that, overall, the 3 Evolve SP Vision is an immersive and interactive driving experience that is right up there with the best of them.

Brawny performance, exquisite agility and a refinement that, collectively, have eluded every small Mazda in living memory until this generation’s 2019 debut. This 3’s right on the money. Still.

The Corolla Ascent Sport Hybrid is a comfortable, stress-free driving experience. Toyota’s series parallel hybrid set-up means the wheels can be driven by the internal-combustion engine, electric motors, or both. And the transition happens seamlessly.

Start-up is silent with the motor(s) doing the driving at low speed, the petrol engine kicking in as the power requirement rises.

As the engine operates it’s also charging the battery and under braking the front wheels turning causes the motor and generator to send power to the main battery pack, as well.

Toyota doesn’t quote acceleration figures for the Corolla but you can expect 0-100km/h in around 12 seconds, which is hardly neck-snapping, however this hybrid combination provides enough torque for nimble acceleration in the city and suburbs as well as easy freeway cruising.

Then there’s the Continuously Variable Transmission. I’m no CVT fan, largely because of the disconnect between road speed and engine speed it creates. The transmission is always trying to keep the engine in its efficiency sweet spot and the most noticeable byproduct is an incongruous droning sound.

Developed by transmission specialist (and Toyota subsidiary) Aisin, the Corolla’s unit is ‘tighter’ than some but the sluggish ‘slipping clutch’ effect is still there from time to time.

Underpinned by Toyota’s TNGA platform, precise handling and excellent ride comfort are dynamic hallmarks of this 12th-generation Corolla. And the Ascent Sport Hybrid Sedan is no exception.

Suspension is by struts at the front and multi-links at the rear, and compliance is super impressive, especially for a car of this size.

The electrically-assisted steering is responsive and road feel is good, the car remaining planted and predictable, with only modest body roll if the red mist descends and you decide to ‘push on’ through your favourite set of corners.

This kind of response is especially noteworthy given the car’s low-rolling resistance Bridgestone Ecopia rubber (205/55) is primarily designed for efficiency rather than race-circuit grippiness.

Braking is by 255mm ventilated discs at the front (slightly smaller than the 2.0L non-hybrid’s) and 265mm solid rotors at the rear. They’re progressive with good pedal feel. Not always the case when regenerative braking is part of the picture.

In terms of general comfort and ergonomic efficiency, the seats remain comfortable, even over road-trip-style stints, while the mix of physical and digital controls is sensible and works well.

The Corolla Ascent Sport Hybrid Sedan boasts a maximum five-star ANCAP rating, although the assessment was in 2018 and the criteria have been dialled up since then.

That said, active (crash-avoidance) tech includes AEB - operating from 10-180km/h (with pedestrian and cyclist detection from 10-80km/h), active cruise control, lane trace assist, lane-keep assist, emergency lane keeping, road sign assist and auto high beam. 

‘Active Cornering Assist’ and a reversing camera are also standard, but sadly, blind-spot monitoring (with ‘Safe Exit Assist’) and rear cross-traffic are optional.

If a crash is unavoidable, there are seven airbags on board (front, front side, full length curtain and driver’s knee). No front centre bag, though.

There are three top-tethers across the back seat for baby capsules or child restraints with ISOFIX anchors on the two outer positions.

Also fitted is a manually-triggered, roof-mounted SOS button for a back-to-base call that can direct emergency services to the vehicle's location if required.

Mazda offers a five-year/unlimited kilometre warranty, with five-years roadside assistance… and that’s nothing special nowadays.

Service intervals are at 12 months or every 15,000km.

A fixed-price service scheme is available, averaging out to $434 annually over the first five years. Mazda shows pricing right up to 16 years and 240,000km on its website.

Toyota covers the Corolla with a five-year, unlimited-km warranty, which is the industry standard these days. But significantly, the hybrid battery is included and if you follow the annual servicing schedule for those five years, your engine and driveline warranty extends to seven years and the battery to 10 years (if the latter is also inspected annually). Impressive.

Seven years emergency assistance is provided (expenses related to car hire or towing), and corrosion (to the point of perforation) is covered for seven years.

On top of that ‘Toyota Connected Services’, accessed through the ‘myToyota’ app, is complimentary for 12 months, offering everything from vehicle data and member discounts to driving insights and multimedia profiles.

Servicing is recommended every 12 months or 15,000km, and ‘Toyota Service Advantage’ capped pricing is available, with the number sitting at $245 for the first five visits to the workshop. 

That’s up from $175 when the current generation Corolla launched here in 2019, but it’s still a sharp price.
