Toyota Corolla vs Audi A3

What's the difference?

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.

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 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.

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.

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.

Sitting behind the driver’s seat set for my 183cm height, I enjoyed good legroom and ample headroom. Three adults will be okay for short to medium journeys and a trio of up to teenage kids will be fine for the long haul.

There’s a fold down armrest with two cupholders built in, although the cushion lowers all the way onto the seat creating a slightly awkward downward angle. And no map pockets on the front seat backs feels a bit stingy.

The rear door bins can accommodate a medium-size bottle and a small tray at the back of the front centre console is where you’d like the adjustable ventilation and USB outlets to be, but sadly, they don’t exist.

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).

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.

These are not bargain basement cars, and with a kick-off price of $46,900 for the A3 35 TFSI Sportback (the hatch version) and $49,400 for the sedan in the same specification, that much is obvious.

The fact is, both the new A3 variants represent a fair mark-up on the previous model. But if you look at the post-Covid car market in a macro sense, you can see the same trend across a lot of brands and a lot of previously entry-level models.

Ante up to the 40 TFSI, and the news is no different with an asking price of $53,500 (Sportback) and $56,000 (sedan).

If the price sounds steep on a per-kilo basis, you need to remember this is an Audi we’re talking about and that price premium is part and parcel of a prestige badge. Don’t like it? Go and buy a VW Golf. That’d be Audi’s advice, anyway.

To justify that viewpoint, the A3 is loaded with some impressive standard kit. The 35 TFSI starts things off with Audi’s vaunted 'Virtual Cockpit', wireless phone charging, voice recognition, Apple CarPlay and Android Auto, remote central locking, paddle shifters, park-assist, sat-nav, a 10.1-inch touchscreen, LED headlights, a multi-function steering wheel, automatic lights and wipers, digital radio, cruise-control and dual-zone climate control.

The 40 TFSI adds a range of aluminium trim pieces and garnishes, Audi’s 'Drive Select' system which allows the driver to choose the characteristic of the dampers, steering response, exhaust sound, throttle response and transmission shift points.

The 40 TFSI also adds sportier front seats, a rear spoiler, body kit, extra courtesy lights around the car and details such as a 12-volt socket in the luggage area.

Options on the base model include a 'Comfort Pack' consisting of adaptive cruise-control, electric front seats, heated front seats, auto dimming headlights, heated and folding mirrors, four-way electric lumbar control and 'Adaptive Drive Assist', including 'Emergency Assist.'

That will set you back $2600, while the 40 TFSI can be enhanced with Audi’s 'Premium Package' which adds those same items as well as aluminium-look trim pieces, a better sound system, head-up instrument display and a memory function for the driver’s seat. That adds $4500 to either the 40 TFSI Sportback or sedan.

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.

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.

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.

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.

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.

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.

Possibly the headline (no pun intended) act here is the inclusion of a centre-front airbag. This is something we’ll be seeing a lot more of in the future, particularly in compact cars, where the proximity of the front-seat passengers can lead to head clashes in a side-impact crash.

Beyond that, the Audi has six airbags including side-curtain airbags.

In terms of driver aids, the A3 sets a high bar for its competitors, and with autonomous emergency braking including pedestrian and cyclist recognition, rear-cross-traffic alert, lane-departure assist and a rear-view camera, most bases are covered.

The major omissions are adaptive cruise-control, but that’s available in the 35 TFSI as part of the $2600 Comfort Package, and in the 40 TFSI as part of the $4500 Premium Package.

Yes, the Premium Package also includes heated, memory front seats, a head-up display, improved stereo and the multi-coloured ambient interior lighting (and more) but it does seem strange that it costs more to option up to adaptive cruise in the 40 TFSI than in the base-model.

The A3 scored the full five stars in ANCAP crash testing in 2020.

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.

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.
