Summary
Audi A3
If it was the original BMW 3-Series that invented the compact luxury car market segment all those years ago, then it’s probably fair to claim it was Audi’s A3 franchise that gave rise to the luxury small-hatch category.
On that basis, any new Audi A3 is news but, in the face of the SUV onslaught (including its own stablemate the Q3) the new small Audi has its work cut out for it.
With this update, there’s refreshed styling, a new interior layout and, for the launch of the new cars, two body styles, a conventionally styled sedan and what Audi calls the Sportback; fundamentally a five-door hatchback but with the German brand’s own flair plastered all over it.

As well as new connectivity and safety tech, the big news is the availability of a mild-hybrid driveline as well as a second powertrain option with more performance from a more conventional layout.
Interestingly, it’s that (mild) hybrid version of the A3 that represents the entry-level variant of the A3. A sign of the times? Perhaps.
As well as the two powertrains, there are two distinct chassis layouts, starting with a front-drive set-up and extending to the option of Audi’s Quattro all-wheel drive (AWD) system.

Mercedes-Benz A-Class
Meet the world’s most aerodynamically efficient passenger car. Mercedes-Benz says the drag co-efficient for this new sedan version of its fourth-generation A-Class is the lowest ever measured for a passenger vehicle.
Which is quite a claim, but you only have to look at it to see how much work has gone into marrying good looks with slippery aero performance.
The A-Class sedan is substantially longer and fractionally taller than its hatchback sibling, but does that mean it’s better, or simply different?

Verdict
Audi A37/10
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.

Mercedes-Benz A-Class8.1/10
Mercedes-Benz knows its way around a sedan, and this A-Class is a well-equipped, comfortable and efficient city-sized four-door.
But more than that, to my eyes anyway, it’s a perfect example of restrained form matching aero function with beautiful results.

Design
Audi A36/10
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.
Mercedes-Benz A-Class9/10
A global carmaker can’t hold its head up in public without a formal design strategy, and Mercedes-Benz uses ‘Sensual Purity’ as a guiding principle in developing the look and feel of its current models. It may sound airy-fairy, but I for one reckon it’s accurate in describing the A-Class sedan.
The overall form is flowing and minimalist, the major exception being a hard character line running down the side of the car from the trailing edge of the angular LED headlights and along the top of the doors to link with the tail-lights.
A rear-biased glasshouse emphasises the length of the bonnet, at the same time delivering a broad, muscular stance with short overhangs front and rear.
Ultra-fine panel gaps, careful sealing around the headlights and curved strakes either side of the bonnet keep the look clean and simple, not to mention super-slippery.
The interior has been styled to within an inch of its life, the dash dominated by the slick twin 10.25-inch widescreen ‘MBUX’ display covering instruments, ventilation, media and vehicle settings.
Five signature, turbine-style air vents (three in the centre, and one at each edge) lift the dash’s visual interest, and the quality of fit and finish is top-shelf.
Practicality
Audi A36/10
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.
Â
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.
Â
Mercedes-Benz A-Class8/10
At a bit over 4.5m long, a fraction under 1.8m wide, and close to 1.5m tall the A-Class sedan is 130mm longer and 6.0mm higher than the hatch version.
The A-Class sedan driver is presented with the same sleek widescreen display as found in the hatch, and storage runs to two cupholders in the centre console, a lidded bin/armrest between the seats (including twin USB ports), decent door pockets with room for bottles and a medium-size glove box.
In a swap to the rear, sitting behind the driver’s seat set to my (183cm) position, I enjoyed adequate knee and headroom, although stretching up a to a straight-back position led to a scalp to headlining interface.
In the A 200 a centre fold-down armrest incorporates two cupholders, again there are generous pockets in the doors with room for bottles, and adjustable ventilation outlets are set into the back of the front centre console. Always a plus.
There are three belted positions across the rear, but the adults using them for anything other than short journeys will have to be good friends and flexible. Best for two grown-ups, and three kids will be fine.
One snag is the size of the rear door aperture. Okay for taller people on the way in, but a limb-unfolding gymnastic exercise on exit.
But of course the reason we’re all here is the boot, and the sedan’s extra length translates to an additional 60 litres of luggage space for a total cargo volume of 430 litres (VDA).
Extra space is one thing, but usability is another. The benefit of a hatch is a large opening that allows bulky stuff to find a home, and Merc has pushed the sedan’s boot aperture to just under a metre across and there’s half a metre between the base of the rear window and the lower edge of the boot lid.
That’s made a big difference and access is good, with the rear seats folding 40/20/40 to add extra flexibility and volume. There are also tie-down hooks at each corner of the floor (a luggage net is included) and a netted pocket behind the passenger side wheel tub (with 12-volt outlet).
At the time of writing Mercedes-Benz wasn’t quoting towing specifications, and don’t bother looking for a spare wheel, the tyres are run-flats.
Price and features
Audi A37/10
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.
Mercedes-Benz A-Class8/10
The A-Class sedan is launching with two variants, the A 200 at $49,400, before on-road costs, and an entry-level A 180, arriving in August 2019 at $44,900.
We’ll cover active and passive safety tech in the safety section, but above and beyond that standard equipment for the A 180 runs to 17-inch alloy wheels, ‘Artico’ faux leather upholstery, the ‘MBUX’ widescreen cockpit display (two 10.25-inch digital screens), auto LED headlights and DRLs, keyless entry and start, auto-dimming rearview mirror, climate-control, sat nav, multi-function sports steering wheel, cruise control, rain-sensing wipers, ‘Active Parking Assist’ (with ultrasonic proximity sensors front and rear), tinted glass, plus nine-speaker, 225W audio with digital radio, as well as Apple CarPlay and Android Auto.
The A200 steps up to 18-inch alloy rims, and adds a dual exhaust system, four-way electrical adjustment for the driver’s seat (with lumbar support), a folding rear armrest (with twin cupholders), adaptive high-beam assist, and a wireless device charging bay.
Under the bonnet
Audi A37/10
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.
Mercedes-Benz A-Class7/10
Both models are powered by the same 1.3-litre (M282) direct-injection four-cylinder turbo-petrol engine as the hatch, the A180 tuned to deliver 100kW (at 5500rpm) and 200Nm (at 1460rpm), with the A 200 bumping that up to 120kW (at 5500rpm) and 250Nm (at 1620rpm).
Drive goes to the front wheels only via a seven-speed dual-clutch automatic transmission.
Efficiency
Audi A37/10
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.
Mercedes-Benz A-Class8/10
Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 5.7L/100km for both models, with a CO2 emissions figure of 130g/km.
Over roughly 250km of open highway driving on the launch program the A 200’s on-board computer coughed up a figure of 6.3L/100km. So, the real-world highway cycle figure is higher than the claimed combined number. Which is a miss, but not a massive one, and fuel-efficiency is still pretty impressive.
Minimum fuel requirement is 95 RON premium unleaded, and you’ll need 43 litres of it (plus a 5.0-litre reserve) to fill the tank.
Driving
Audi A38/10
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.
Mercedes-Benz A-Class8/10
Three things stand out on first meeting with the A-Class sedan – ride comfort, steering feel, and road noise, or rather the lack of it.
The ‘biggest’ compliment you can pay a small car is that it rides like a bigger one, and behind the A 200’s wheel you’d swear the wheelbase was appreciably longer than the 2.7 metres it actually measures.
Over long undulations, even higher frequency bumps and ruts, the A-Class remains stable and composed thanks to a thoroughly sorted (strut front, torsion beam rear) suspension, with beautifully progressive damping a particular highlight.
Electromechanically-assisted steering points accurately and delivers good road feel without any undue vibration. And despite the A-Class launch drive loop covering typically coarse-chip bitumen roads through rural Victoria, overall noise levels remained impressively low.
Acceleration is brisk rather than properly sharp, but in the A 200 there’s more than enough oomph to keep things on the boil for easy highway cruising and overtaking.
With maximum torque available from just above 1600rpm, and a seven-speed dual-clutch auto transmission keeping revs in the sweet spot, the A 200 breezes through the cut and thrust of city traffic, too.
Auto shifts are smooth and quick, with manual changes via the wheel-mounted paddles adding even more direct access to your ratio of choice. And the bonus is no sign of the slow-speed shuntiness sometimes exhibited by dual-clutch autos, especially in twisting, three-point parking manoeuvres.
Special call-out for the cruise control which responds to adjustments quickly (including 10km/h jumps up or down with a firm press of the thumb) and rapidly retards downhill speeds.
Several unbroken hours in the front seat couldn’t generate a twinge of discomfort, the brakes are strong, and over-shoulder visibility is marginally better than in the hatch (not that it’s a weakness in the latter).
Add the sleek and intuitive multimedia system, high-quality audio, plus excellent ergonomics and you have a neatly resolved compact sedan that’s easy to use in the city and suburbs, keeping solid road-tripping ability up its sleeve as well.
Safety
Audi A38/10
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.
Mercedes-Benz A-Class10/10
Think automotive safety and Mercedes-Benz will be one of the first names to pop into your mind, and the A 180 offers in impressive suite of active features including ABS, BA, EBD, stability and traction controls, a reversing camera (with dynamic guidelines), ‘Active Brake Assist’ (Merc-speak for AEB), ‘Adaptive Brake’, ‘Attention Assist’, ‘Blind Spot Assist’, ‘Cross-wind Assist’, ‘Lane Keep Assist’, a tyre pressure warning system, the ‘Pre-Safe’ accident anticipatory system, and ‘Traffic Sign Assist’. The A 200 adds ‘Adaptive Highbeam Assist’.
If all that fails to prevent an impact you’ll be protected by nine airbags (front, pelvis and window for driver and front passenger, side airbags for rear seat occupants and a driver’s knee bag), and the ‘Active Bonnet’ automatically tilts to minimise pedestrian injuries.
The A-Class was awarded a maximum five ANCAP stars in 2018, and for smaller occupants there are three child restraint/baby capsule top tether points across the back seat, with ISOFIX anchors on the two outer positions.
Ownership
Audi A37/10
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.
Mercedes-Benz A-Class7/10
Mercedes-Benz covers its passenger car range with a three year/unlimited km warranty, like the other two members of the German ‘Big Three’ (Audi and BMW) .
That lags behind the mainstream market where the majority of players are now at five years/unlimited km, with some at seven years.
On the upside, Mercedes-Benz Road Care assistance is included in the deal for three years.
Service is scheduled for 12 months/25,000km (whichever comes first) with pricing available on an ‘Up-front’ or ‘Pay-as-you-go’ basis.
Pre-payment delivers a $500 saving with the first three A-Class services set at a total of $2050, compared to $2550 PAYG. Fourth and fifth services are also available for pre-purchase.
