Audi A3 vs Holden Astra

What's the difference?

Producing a car that takes the end result beyond appliance status is no given in a world car-park dominated by SUVs. But Audi has, over the last few decades, shown it is very good at doing just that and the latest incarnation of its A3 stalwart backs that up.

While it might take a bit of mental gymnastics to understand why the base model gets the hybrid driveline, or why the more expensive variant costs more to option with adaptive cruise-control, the fact remains these are driver’s cars from a company that understands that concept.

Yes, the A3 is a relatively expensive way to arrive at a compact hatch or sedan, but if you value the journey as much as the destination, it will all make sense.

While the technical aspects of the 35 TFSI are interesting, the extra power and all-weather grip of the AWD 40 TFSI seem to be worth the additional dollars to us. The A3 has always been a sporty alternative, meaning the sportiest version is the one for us.

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.

It’s actually refreshing in 2022 to see a carmaker putting such an effort into something that isn’t an SUV.

That Audi has bothered with two distinct bodies and two equally distinct drivelines is also one for the books, really.

Technically, the mild-hybrid driveline as seen in larger Audis in recent years is probably the highlight of the new A3, and even though it doesn’t compare with a conventional petrol-electric hybrid, it demonstrates Audi’s attention to detail.

The same goes for the digital instruments which allows the driver to tailor the information displayed at any given time. Need a city map more than you need a tachometer at a particular point in you journey? That’s where this technology comes into its own.

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.

Although it’s a compact car externally, clever packaging means there’s ample space inside. Even a tall-ish rear-seat passenger can sit behind a tall-ish driver, and the sculpted rear seat-backs help make that possible.

The only complaint would be that the dark headlining material makes the interior a bit of a cave at times.

Paying more for the 40 TFSI gets you extra cargo nets on the front seat backrests and luggage area, 12-volt sockets in the rear seat and boot. Both versions get floor mats and a centre arm-rest front and rear.

The rear seat in either is split 40/20/40 for a range of possibilities, with the Sportback offering 325 litres (VDA) for the Sportback quattro models, and 380L (VDA) for the 2WD models and its boot capacity is increased to 1145L (VDA) with the rear seat folded flat. The luggage space in the sedan is 390L (VDA) for the quattro AWD version, and a more capacious 425L (VDA) for the FWD model.

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.

While both versions of the A3 use a seven-speed dual-clutch transmission (no manual gearbox will be offered) there’s not a lot of commonality beyond that.

So let’s start with the 35 TFSI’s mild-hybrid running gear. To begin with, mild-hybrid in this sense refers to a starter motor/alternator unit that is linked to a 48-volt battery (the car also has a conventional 12-volt electrical system).

When coasting, the engine can shut off and the starter switches to alternator mode and harvests the otherwise lost energy to charge the 48-volt battery. This 48-volt system also powers the car’s functions when the engine is switched off.

When the car needs to restart (when the traffic-light goes green) the starter kicks in, using that harvested voltage. There’s also a regenerative braking function, saving the car’s actual brakes for more severe stops.

Unlike a 'normal' hybrid system, there’s no electric motor to help drive the car, but Audi claims a potential fuel saving of 0.4 litres per 100km from the set-up. Any benefit will be most noticeable in urban running where the car is speeding up and slowing down regularly.

The rest of the 35 TFSI is technically interesting, too, with the 1.5-litre four-cylinder turbocharged engine featuring cylinder-on-demand where it can shut down individual cylinders during cruise conditions to save fuel.

When firing on all four, however, the engine is good for 110kW of power and 250Nm of torque, figures which have become almost an industry standard in this sized vehicle.

The 40 TFSI, meanwhile, ditches the hybrid gear for a conventional 2.0-litre powerplant with a turbocharger and 140kW of power. Torque is a handy 320Nm and is developed over a wide range of engine speeds (anywhere from 1500 to 4100rpm).

The other big difference is in the driveline. The 35 TFSI is a front-wheel drive platform while the 40 TFSI uses Audi’s Quattro AWD as it applies to Audis with an east-west engine layout.

That means the car behaves as a front-drive vehicle until the electronics decides more power should be sent to the rear wheels. At that point, anything up to 99 per cent of the available torque can be transferred rearwards via an electronically-controlled multi-plate clutch housed at the rear of the car, just in front of the rear axle.

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.

With all its cylinder shut-off, hybrid tricks and small capacity, the 1.5-litre engine boasts a 5.0 litres per 100km combined cycle fuel economy figure.

Combined with its 50-litre tank, that’s a potential for 1000km between service-station visits. It’s also commendably close to the numbers you’d expect from a similarly sized vehicle with a turbo-diesel engine.

The more conventional 2.0-litre A3 variant, meanwhile, boasts a still-credible 6.7 litres per 100km for the same test. To counter its greater thirst, Audi has fitted a slightly bigger, 55-litre fuel tank.

The headline act, of course, is the base-model’s highway figure which, thanks to the small capacity engine and its reduced pumping losses at small throttle-openings, can get right down into the low-fives (5.0 litres per 100km) in the real world at real highway speeds.

With a tail-wind, you might even see a number starting with four. This is why you don’t need a diesel engine any longer.

Expect the 40 TFSI to use roughly a litre more across every 100km travelled. And in either case, you are stuck with paying for 95-RON premium unleaded.

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.

Let’s start with the less powerful 35 TFSI, if only because - even though we know better in 2022 - there’s a temptation to think a 1.5-litre engine will be underdone. The reality, however, is that you’re not going to drive this car and judge it as anything other than very resolved.

While it’s true the peak power of 110kW isn’t startling, it’s the way it’s delivered (along with the 250Nm of torque) that sets the mood here.

Like many late-model Audis, this one has an engine with a fizzy, zingy feel that makes you want to rev it just to hear and feel it. And when you do, it pays off with plenty of flexibility and a sophisticated, refined feel.

Whether the mild hybrid driveline is adding anything to the formula is debatable, because the technology is so seamless you won’t pick what it’s doing other than the engine stop-start function, which is one of the better ones we’ve sampled.

Move from the 35 into the 40 TFSI and you immediately notice the extra power and torque on tap. And although it’s still not a hot-hatch by modern standards, there’s always enough urge to make the 40 TFSI a convincing driver’s car.

Again, the power delivery is the key to it all, making more of what the engine has to offer by actively encouraging you to use it. The seven-speed dual-clutch transmission is your friend here.

The extra driveline functionality of the 40 (namely the AWD system) actually means less than you might imagine in day-to-day life. We didn’t get to drive the car in the wet, but it’s fair to say that those conditions (or a loose, gravel road) are really the only ones likely to make a difference to the way the basic platform feels.

That’s for two reasons; the first being the all-wheel-drive is fundamentally on demand anyway and, secondly, the basic platform is so composed and balanced in the first place, that the Quattro system will spend a lot of its time hiding in the background.

The 40 TFSI also get the selectable drive modes which break with tradition by actually making a difference to the way the car feels.

But the reality is that if you took the best bits of every other setting (Comfort, Dynamic and Efficiency) and loaded them into the Individual button, you’d probably wind up with something very close to what the non-adjustable 35 TFSI offers in the first place.

You have to admire the way Audi has made a front-drive car in the A3 steer, handle and talk to the driver in such a clear, precise way.

Yes, the 40’s selectable modes add another layer to that, but only if you can be bothered. Even more than that, the A3 in either form feels like its ultra-stable and safe, while the levels of feel and feedback give the impression they were decided upon by people who enjoy driving.

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.

Audi recently improved its factory warranty from three years to five years and unlimited kilometres. Any new Audi (including this one) sold after January 1 this year is the beneficiary of that change.

Audi specifies service intervals of 15,000km or 13 months.

There’s also the option of a fixed-price servicing program for the first five years of A3 ownership, and that will cost you $2250, for an annual average of $450.

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.
