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.
|Engine Type||1.3L turbo|
|Fuel Type||Regular Unleaded Petrol|
Audi’s A3 is one of the most affordable ways into this prestige German brand. But like some amusement park mirror maze you’ll find with so many A3 variations there are numerous, seemingly identical ways into the model.
Which one do you choose? There’s a sedan, a hatch, and a convertible with four different engines, not to mention front- or all-wheel drive.
That’s why this range review is here – to guide you through the A3 hall of mirrors, and identify the right model for you.

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.
Would your preference be an A-Class with a hatch or a boot? Tell us what you think in the comments section below.
The Audi A3 is now five years into this current generation and it’s beginning to show its age in terms of tech and styling in the cabin, despite updates adding new equipment. It’s expensive compared to most small cars but is spot-on for a prestige vehicle.
The Sedan is, in my view, the best looking small sedan on the planet and offers the biggest boot space in the A3 range. The Sportback, however, is arguably more practical, with better legroom, headroom and cargo carrying ability (with the rear seats down). The Cabriolet has the same perfect proportions as the sedan, but like all good convertibles doesn’t make practicality a priority.
The sweet spot of the range would have to be the Sportback 2.0 TFSI quattro S Line with its $50,000 list price making it the most affordable but most 'specced up' A3 in the entire range.
You have $50,000. Do you buy an entry-grade Audi A3 Cabriolet, a 2.0 TFSI Sport Sedan or a Volkswagen Golf R? Tell us what you think in the comments below.
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.
The A3 comes in three body styles: a five-door hatch, which Audi calls the Sportback; the four-door Sedan, and a two-door convertible which it refers to as the Cabriolet. It may not surprise you to learn they're all different sizes, too.
The Sportback doesn’t look like the shortest of the three but at 4313mm end-to-end it’s 145mm shy of the Sedan and 110mm shorter than the Cabriolet. But those exterior dimensions don’t tell the whole story on interior space. So, which one is more practical? We’ll get to that.
But first, the looks. The Sportback has a wagon-like appearance with its large (for a hatch) rear quarter windows. If you think it looks longer than a regular hatchback, you’re right: a Volkswagen Golf is 50mm shorter even though it shares the same platform as the A3.
However, unlike the Golf, there’s something about the Sportback’s proportions which doesn’t seem balanced.
Then there’s the A3 sedan. Now this is a perfectly proportioned car. Looking like a miniature version of the A8 limo, the A3 is one of the only tiny sedans on the planet that looks fantastic.
The Cabriolet is based on the Sedan, and it too looks beautifully proportioned. Soft tops, when they’re up, never do much for a car’s profile. Be it a Bentley or an A3, they always look better down. When the roof is down the A3 appears lower, sleeker, and tougher.
While all A3’s have the same grille and headlight design the rear treatment of the Sedan and Cabriolet is more refined with their blade-like tail-lights and boot lid lip, than the Sportback, even if it does have a roof-top spoiler.
Interiors are identical across each A3 grade, the cabin benefiting from excellent fit and finish and the use of high-quality materials. But if you like bling-tastic cockpits, maybe you should be looking at a Benz A-Class because even the fanciest A3 money can buy, the RS3, comes with a small display screen and a rather low-key interior design.
As for rivals, the new A-Class (which I’ve just reviewed) is a glitzy competitor in hatch form, with a soon-to-arrive sedan going head-to-head with the little Audi as well.
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.
The Sportback and Sedan have five seats, while the Cabriolet has four. Leg and headroom in the back row for all body styles is limited. The Sportback will give you the most rear legroom, while the sedan has a few millimetres more space for your knees than the Cabriolet.
At 191cm tall I can sit behind my driving position in the Sportback with a pinkie finger’s space, while my knees brush the seatback in the Sedan, and the Cabriolet won’t accommodate my long legs back there at all.
Rear headroom in the Sportback isn’t bad with enough room for my big head to clear the ceiling thanks to that tall(-ish) flat roofline while the sedan is a tighter fit but I just make it under. The Cabriolet’s low fabric roof means only small adults or kids will be able to sit up straight back there – unless the top is down and then you have literally unlimited headroom.
Boot space varies obviously depending on the body style. The Sedan has biggest cargo capacity with 425 litres, the Sportback offers up 340 litres, but fold those rear seats down and you have 1180 litres at your disposal, plus a bigger aperture to fit stuff in. The Cabriolet’s folding roof eats into the boot space, but you’re still left with 320 litres even when it’s down.
The folding roof is automatic and can be raised or lowered at up to 50km/h, but it’s slow - I’ve timed it and it takes about 20 seconds to open or shut.
Storage throughout the cabin is limited, too. There are two cupholders up front in all cars, while the Cabriolet is the only A3 to have two cupholders in the back (they’re between the rear seats). If you want cupholders in the rear of the Sedan and Sportback you’ll have to option the $450 fold-down armrest which houses them.
All grades above the 1.0 TFSI come with storage nets in the seatback and front passenger footwell, 12-volt sockets in the rear centre console and boot, plus cargo nets back there, too. There’s a USB jack in the centre console of all A3s.
Price and features
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.
The A3 isn’t great value for a small car, generally speaking, because while you are getting a high-quality prestige vehicle, it doesn’t come with a mountain of equipment that you might find on a more affordable little hatch or sedan.
Look at it this way: take $40 into a fish and chip shop and you’ll walk out with your arms full of food, take the same amount into a Michelin-starred restaurant and you’ll be lucky to get an entrée. Same with buying a prestige car – and the A3 really is a starter on the Audi menu.
Coming standard on the entry-grade $36,200 1.0 TFSI Sportback are xenon headlights with LED running lights, cloth upholstery, dual-zone climate control, a 7.0-inch touchscreen with sat nav, reversing camera, multimedia system with voice control, eight-speaker stereo, Bluetooth connectivity, CD player, front and rear parking sensors, rear view camera and 16-inch alloy wheels.
Only the Sportback comes in this 1.0 TFSI grade. The rest of the body styles start with the 1.4 TFSI ($40,300 for the Sportback; $41,900 for Sedan; $49,400 for Cabriolet) which comes with the 1.0 TFSI’s equipment but swaps the cloth seats for leather upholstery and adds paddles shifters, aluminium-look interior elements and 17-inch alloy wheels.
Stepping up to the 2.0 TFSI Sport ($46,400 for Sportback; $48,000 for Sedan; $55,500 for the Cabriolet) adds leather sports front seats, aluminium door sills, Apple CarPlay and Android Auto, and 17-inch alloys with a different design.
The 2.0 TFSI quattro S line ($50,000 for the Sportback; $51,600 for Sedan and $59,100 for the Cabriolet) brings in lowered sports suspension, 18-inch alloys and LED headlights.
Each grade also attains more safety equipment, which we’ll cover further on.
I’ve also reviewed Mercedes-Benz’s new A200, which is a good model comparison for the A3. At a list price of $48,200 the 1.3-litre four-cylinder A200 is pricier than the 1.4 TFSI, but offers better value than the A3 2.0TFSI with more equipment, including two 10.25-inch display screens.
As for paint colours, only 'Brilliant Black' and 'Ibis White' won't cost you a cent more. Optional colours include 'Cosmos Blue', 'Tango Red' and 'Monsoon Grey'.
Engine & trans
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).
Now on to the engines. Yes, I’m doing this in what may seem a strange order, but trust me, it’s to guide you safely through the A3 range without anybody getting lost. We don’t leave anybody behind here, not on my watch.
The grades indicate the engines in the A3 line-up – the higher the grade, the more powerful the engine. So, the range starts with the 1.0 TFSI which has a 85kW/200Nm 1.0-litre three-cylinder engine, and steps up to the 1.4 TFSI which has a 110kW/250Nm 1.4-litre four-cylinder with cylinder on demand (COD) letting it run on two cylinders when not under load). Both are front-wheel drive (FWD) cars.
Next rung up is the 2.0 TFSI Sport and that has a 2.0-litre four making 140kW/320Nm with drive going to the front wheels. The top of the range is the 2.0 TFSI quattro S line which has the same engine but is all-wheel drive (AWD).
Those are all turbo-petrol engines – yes, no diesels and no manual gearbox option either. All have a seven-speed dual-clutch automatics shifting the gears.
If you’re after something more hardcore in the same package, there are two halo ‘models’ that sit above the A3 range: the S3 with a 213kW/380Nm 2.0-litre turbo-petrol four and the RS3 with its 2.5-litre five-cylinder turbo-petrol making 294kW/480Nm.
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.
Fuel usage depends on the engine and body style, with weights varying across the range. The most fuel-efficient engine is the 1.0-litre which is only offered on the Sportback, and Audi says over a combination of urban and open roads you should see it use 4.8L/100km.
The 1.4 TFSI Sportback uses 5.0L/100km, while the Sedan uses 4.9L/100km, but the heavier Cabriolet drinks more at 5.1L/100km.
My most recent A3 test car was a 1.4 TFSI Sportback and the trip computer reported 7.6L/100km over a mix of city and country kays - not bad.
The 2.0 TFSI Sport Sportback uses 5.9L/100km, the Sedan needs 5.8L/100km, the Cabriolet a bit more at 6.0L/100km.
The 2.0 TFSI quattro S Line Sportback uses 6.2L/100km, while the Sedan will go through 6.1L/100km and the Cabriolet again is highest with 6.4L/100km.
That raises the question of how much more does the Cabriolet weigh? About 170kg more than the Sedan and Sportback thanks to the extra reinforcement needed to strengthen the body to compensate for the rigidity it loses by not having a fixed metal roof.
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.
I’ve driven all A3 variants from the 1.0 TFSI to the 2.0 TFSI quattro S Line, plus the S3 and RS3, but most recently I tested the 1.4 TFSI Sportback, which I’ll focus on here.
Our car was fitted with two optional packages – the 'Style Package' which adds LED headlights, 18-inch alloys and sports suspension, and the 'Technik Package' which brings a virtual instrument cluster, an 8.3-inch display and sports steering wheel.
Those larger 18-inch alloys wearing low profile 225/40 Hankook Ventus S1 Evo2 tyres look great, but like thin-soled shoes you’ll feel every imperfection on the road giving a harsher texture to the ride, plus they can be noisy on course-chip bitumen.
I’d stick to the standard 16-inch wheels. Sure, they don’t look as racy, but the ride from those, on 55 profile tyres, is a lot more cushioned.
Despite that grittier feel from the tyres the sports suspension is excellent and manages to soften bigger bumps well. Handling is good too, thanks to that suspension keeping the body well controlled.
Good visibility, steering that’s light but offers decent feel, and a comfortable seating position make the A4 pleasant to pilot, but not hugely engaging. If you're after more of a driver’s car, the S3 and RS3 will deliver – trust me.
Acceleration isn’t bad from the 1.4-litre, with 0-100km/h claimed to be 8.2 seconds. That dual-clutch transmission is a quick shifter and smooth even in bumper-to-bumper traffic, but only if you turn off the stop-start engine system (jerky and hard to tolerate).
I’m also not a fan of the way the stop-start system switches the engine off as you coast to a stop at traffic lights and intersections. For me, that borders on a safety issue, particularly when needing to turn on an amber only to find you momentarily lack steering or power.
As mentioned in the engine/transmission section, the 1.4 TFSI Sportback is a FWD car. Put it on a steep hill, as I did on our test incline, and even in dry conditions it’ll lose traction under hard acceleration. Traction control reins the slippage in, but AWD 'quattro' cars won’t struggle for traction in the same circumstances.
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.
The A3 has a maximum five-star ANCAP rating from its 2013 crash test, which applies to the Sportback, Sedan and Cabriolet.
While the Sedan and Sportback have seven airbags, the Cabriolet has just five, missing out on the head-level curtain bags.
The amount of advanced safety equipment increases as you step up through the grades, but AEB is standard across the range. Lane keeping assistance, blind spot warning and rear cross traffic alert becomes standard from the 2.0 TFSI Sport upwards, while the lower grades can attain these with the optional $1500 'Assistance Package'.
For child seats there are two ISOFIX mounts and two top tether anchor points across the back seats in the Sedan, Sportback and Cabriolet.
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.
