Audi A3 vs Subaru Liberty

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.

CarsGuide attended this event as a guest of the manufacturer, with meals provided.

The Liberty has a lot going for it - a great reputation for reliability, it isn't terribly priced (although servicing is a little steep) and has that signature all-wheel drive. While I've complained about the ride and handling, apart from STi and RS-badged versions, that has never been the Liberty's strong suit.

While it might be a shrinking part of the market - and Subaru is a founding architect of the modern SUV cult - Subaru and its competitors still care. The Liberty, like Forester and Outback, remains a stand-out in the sector with a boxer 2.5 and all-wheel drive. Sometimes that kind of individuality is enough.

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.

Here's a thing - this week I regularly parked my car in the same street as a fourth-generation Liberty. I kept heading for it at the end of each day because that design feels a lot more contemporary than the current car.

I came to my senses every time before trying to get in, but it does tell you that today's machine is a little on the dowdy side. While not the horror of the lines-everywhere-slab-sided fifth-generation model, I don't think the styling has escaped unscathed from the mess of the car it replaced.

This one won't scare small children or start pub arguments, though, and is a more cohesive, gracefully-ageing design. The LED daytime running lights and, in the case of the Premium, LED headlights, give it a modern feel and its less imposing headlight design is rather more pleasing. 

Little has happened as part of the refresh, with just the requisite number of visual tweaks. The front and rear bumpers (now with subtle diffuser) are a bit sharper and new wing mirrors and grille all add a little extra - but not much - to the 2014 original.

Inside is pretty much the same as before. The touchscreen has a flat, glare-prone screen but the rest of the cabin is well thought through, if entirely conventional. The flashy alloy pedals are a fun touch, though, and the materials choices are solid if uninspiring.

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.

The Liberty has a terrifically spacious interior. Rear seat passengers have a huge amount of legroom, with a ton of room behind my driving position (I'm 178cm) for long-legged teenagers. There's also plenty of legroom and even air vents.

The cabin has four cupholders in total and four USB ports, two up front and two in the back.

If you found a way to fill the boot with water you'd get 493 litres aboard and you can drop the 60/40 split fold seats for yet more space.

The Liberty's sixth-generation has arrived at middle age and Subaru took the opportunity to tweak the specification as well as the looks. Second in the three car range is the 2.5i Premium, which sits between the 2.5i entry-level and the 3.6R, and carries a $36,640 price tag.

Standard on the Premium are 18-inch alloys, a six speaker stereo with Bluetooth and USB, dual-zone climate control, keyless entry and start, active cruise control, powered and heated front seats, sat nav, auto high beam, active LED headlights, a very impressive safety package, partial leather seats, leather steering wheel, power everything, sunroof and a full-size spare.

The 7.0-inch touchscreen now not only features sat nav and a half-decent media system but also has Apple CarPlay and Android Auto, which is still a rarity in this class. Also a rarity is the standard all-wheel drive system (good) and the CVT auto (maybe not so good).

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.

Like the overall specification, the drivetrain has received some attention. While power outputs are the same as before - 129kW/235Nm - the CVT auto with which Subaru's 2.5-litre boxer engine is paired is slightly improved. Even in the quiet of the cabin you hear that 'flat' four-cylinder's trademark gravelly growl.

Being a Subaru, all four wheels receive their share of power. The Liberty's published towing capacity is 1500kg for braked trailers and 750kg unbraked. If you need a bit more, the six-cylinder 3.6R can handle another 300kg.

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.

Subaru says the combined cycle fuel figure is 7.3L/100km and I got 9.3L/100km with a mix of suburban and 80km/h running.

The fuel tank is a generous 61 litres.

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.

Subaru says the Liberty has undergone some changes to improve the driving experience. To my backside, that hasn't worked out perhaps as intended. At least I hope so, because the results aren't terrific. The ride is particularly odd - in the corners there is noticeable body roll but it bangs and crashes over bumps, the rear passengers suffering worse than those up front.

In the cruise it's perfectly reasonable and the car is very quiet, indeed it's pleasant at speed. At lower speeds, there is a lack of feel contributing to the feeling that the wheel lacks accuracy. Nothing dramatic, but I felt like I was constantly correcting it the way Parisians correct my high school Francais.

Cheeringly, what I expected to be my least favourite part of the car was quite good. I am monotonously on record dissing CVTs because generally, they're pretty terrible. After six months with one in the Forester, I was never comfortable with it. 

Here in the Liberty, it seems better integrated with the engine, with much better control of the trademark flaring and it's only when you really get the accelerator up against the firewall that you're reminded you're driving a rubber band. When you switch from I (Intelligent) to S (Sport) mode, it also responds accordingly, but there's never going to be fireworks.

The brake pedal is a bit on the mushy side, too, but its stopping ability was never in doubt. I guess the final verdict is that some parts of the experience are dreamily isolating while others are not as good as you might expect.

The Liberty ships with seven airbags (including driver's knee), lane-keep assist, adaptive cruise with brake light recognition, ABS, traction and stability controls, reversing camera, forward and side view cameras, reverse cross traffic alert and blind spot monitoring. 

Bafflingly, there are no parking sensors at all on any Liberty. I know that sounds churlish, but I don't park watching a camera and like the beepers so I can watch somewhere else. Give me a beeper and a dipping left-hand mirror any day.

On top of all that, the 'EyeSight' system is also fitted. EyeSight is a pair of cameras pointing forward that not only powers the lane keep assist, but lets you know if you're drifting or approaching an obstacle too quickly. It also detects pedestrians and in this latest iteration will work up to 50km/h rather than 30km/h as before.

As you might expect, the Liberty scored five ANCAP stars in December 2014.

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.

At three years/unlimited kilometres, the Subaru warranty is now starting to look a bit thin compared to, say, Korean rivals. Over the three years of the capped-price servicing you'll wear $2281.66 for up to 75,000km of servicing. 

Subaru expects to see you every six months or 12,500km, so that averages out to $380 per service.

Hyundai's Sonata will cost you just $795 over the same period (for fewer visits), a Mazda6 will only hit you for between $308 and $336 per service, and a Camry will cost just over half what Subaru charges every year.
