Mazda 3 vs Holden Astra

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.

The Astra's biggest problem is probably the Holden badge. Despite the company's best efforts, some buyers are wary of the company's longevity and some of the other cars in the range do the Astra no favours - Trax, Colorado and Barina feel cheap, because they are. The Astra isn't cheaply made and holds up very well in excellent company.

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 Astra is a sleek if slightly anonymous-looking thing. Having said that, it's a really nice design that looks more expensive than it is. That's important in this segment. Holden is at pains to tell us it's from Germany (the Astra is manufactured in Poland) and it does look Euro-influenced. Despite its coupe roofline, it's an easy in-and-out proposition but does sit a little lower than, say, an i30.

The odd blacked-out section of the C-pillar takes a bit of getting used to but the sheetmetal is otherwise faultless and well put together.

Inside it's a sea of grey plastic and various shades thereof, but again, it hangs together really well and is a welcome change from the Teutonically angular Golf. The materials are largely reasonable, but for some reason the stalks feel flimsy to touch and use.

The cloth trim is hardy but comfortable and I was grateful for its relative coolness versus what you might expect from the textile leather you're more likely to get at this level.

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…

Riding in the front, there's room aplenty for passengers, with good headroom and a well-designed space to maximise what's available. Rear seat passengers do okay as long as the front occupants are being generous, but the seat itself is comfortable and there's even good headroom, despite the falling roofline.

Only the front scores cupholders, with the rear passengers making do with door pockets that might swallow a small bottle. There isn't an armrest or air vents back there either.

There's somewhere for one front occupant to put their phone, a horizontal slot that doesn't like phones with covers or the larger format iPhones or Androids. If your phone does fit (iPhone Xs do, as it happens), it's useful because it's in your eyeline, although a bit untidy if you're plugged into the USB.

The boot starts at a class-compeititve 360 litres, rising to 1210 when you fold the seats down.

The Astra range opens with the R which, typically, you'd expect at the other end of the range with a lot more power, but there you go. You'd think the R+ was even more of a beast, but marketing is an imprecise science... apparently.

R isn't for racing, in our case it was a very bright shade of red. Starting at $23,740 for the auto (you can get a manual for a few bucks less), you get 17-inch alloys, a six speaker stereo, cloth trim, air-conditioning, reversing camera, power windows and mirrors, rear parking sensors, cruise control, auto headlights and wipers, remote central locking and a space-saver spare tyre.

The seemingly tiny screen (it's actually a competitive 7.0-inch unit) runs Holden's 'MyLink' but also has Apple CarPlay and Android Auto. For some reason you have to tell it to use those two useful additions rather than the system picking them up through the USB. Mystifyingly the button is marked 'Projection'.  Aside from that, the system works well and sounds alright.

The reversing camera is of limited use - you'll see what's behind you but it's very flattened out and super-grainy.

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 whole Astra range is turbo, but here in the cheaper seats it's a surprisingly capable 1.4-litre unit with 110kW and a healthy 240Nm. Power finds the road via the front wheels and a six-speed automatic. It's an otherwise unremarkable technical story, with start-stop to help cut fuel use.

The Astra is rated to tow 750kg unbraked and 1200kg braked.

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.

Holden claims the Astra will drink standard unleaded at the rate of 5.8L/100km on the combined cycle.

Our time with the car, which was a 70/30 mix of suburban and highway, yielded 8.3L/100km, and it's worth noting it was stinking hot for most of the time, so the air-con had to work hard.

The fuel tank is a little on the small side at 48 litres, between five and 10 litres smaller than some of its competitors, like i30 and Golf.

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.

That describes the torquey urge of this big 2.5L four, paired perfectly with the sensibly-geared auto.

We miss Mazda’s magnificent manual immensely, but the 3’s instant response reflects its favourable circa-100kW/tonne power-to-weight ratio.

And, as we’ve harped on in the past, the twin-cam unit’s extra oomph beyond 4000rpm delivers muscular high-speed responses akin to a good turbo – or a great old-school Alfa. You can keep your laggy dual-clutch transmissions, Europe.

Now, sweet, smooth and speedy performance is one thing, but having the chassis tuned with precise and fluid steering for tactile handling, and confident roadholding, backed by nuanced driver-assist and traction controls, are another.

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.

I'm going to get my biggest gripe with the Astra out of the way first - the driving position is rendered awkward by the pedal placement. Every other part of the driving experience is perfectly fine, with good adjustment in the seat and steering wheel but the pedals are Not Right. The transition from accelerator to brake means a big lift of the right foot rather than a sideways shuffle and that gets boring. Perhaps I'm getting old and my knees are weak, but I ended up left-foot braking for a lot of the time.

On with the show. The Astra's 1.4 litre turbo is a punchy thing, more than vaguely reminiscent of Peugeot's excellent 1.2 in the 308. The six-speed auto isn't quite as well sorted, occasionally lurching a bit on light throttle like a dual-clutch. The pay-off for that is crisp shifts and a positive feel for most of the time.

The thing about the Astra is that it really takes it to its competition from behind the wheel. It feels almost as good as a Golf, i30 and arguably is as good as a Mazda3 thanks to its extra torque and better refinement.

It's very quiet, composed and is good fun if you like that sort of thing. Otherwise, it's streets ahead of the Corolla which continues to sell like it's going out of fashion.

The Astra R+ has six airbags, ABS, stability and traction controls, reversing camera and forward AEB with a delightfully simple yet effective head-up warning.

The Astra range (with the exception of the lowest-spec R) scored a five-star ANCAP safety rating in November 2016.

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.

Holden's three year/100,000km warranty includes roadside assist for the duration. You can also extend the warranty by up to three years or to 175,000km, for an extra cost.

Servicing is scheduled every nine months or 15,000km. Holden calls its fixed-price servicing 'Know Your Price' and it applies for the first six services (63 months or 105,000km). The first four services are set at $249 each, and the final three $309.
