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 was the first to market with a premium small performance sedan in 2014, with its four-door S3 combining luxury appointments with a punchy engine.
The German brand has largely enjoyed free air in the somewhat niche segment, but now Mercedes-AMG has launched its A35 sedan and BMW's 2 Series Gran Coupe-based M235i is set for a 2020 introduction to try and steal some of the S3's thunder.
With a new-generation version expected around the corner, Audi has updated its S3 with more kit to keep things fresh against its new rivals.
Now priced at $65,800 in sedan form, and $64,200 for the five-door Sportback hatch, does the S3 still have what it takes to stave off the competition?

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.
Despite being close to the end of its lifecycle, the Audi S3 sedan remains a solid choice for those looking for punchy performance wrapped in a premium package.
There is a bit of a trade-off in comfort for the extra performance, but it never strays towards being too unbearable or unliveable.
If you can survive with just using the rear seats occasionally, the S3 sedan also serves up one of the best front-seat interiors on the market, even after all this time.
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.
While you might struggle to fit something like a full-sized bike into the boot of the sedan, the extra cargo capacity would easily accommodate extra grocery bags or a stroller.
We actually think the sedan looks better than the hatch, as the styling is a little more mature and grown up. It actually looks like a shrunk down A4!
The 19-inch wheels fitted to the S3 also help fill its slightly blistered wheelarches, while subtle nods to its sportiness can be seen in the red brake callipers and quad exhaust tips.
The rest of the S3 sedan is unmistakably Audi thanks to its singleframe front grille, strong shoulder line and contrasting side mirrors.
Inside, sports seats with Audi's unique diamond-quilting are fitted for the front occupants, while the rear bench seats also feature the bespoke finish – at least on the outboard pews.
Between the driver and front passenger sits a small storage cubby, the gear shifter, multimedia controls and two cupholders.
In the centre stack, you will see climate controls, the drive mode selector and a small screen above circular air vents.
Everything in the cabin is laid out in a clever, ergonomic fashion, though we will note the central cupholders won't be much use for anything bigger than a small coffee cup.
The best part of the interior is easily the virtual cockpit, which lays out all the information you need right in front of you. It's even customisable, so you can adjust the sizing of the satellite navigation maps or media system.
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.
Being a small sedan, the S3 doesn't exactly boast heaps of interior space, but there is enough for a young family or a group of four adults over short distances.
Our head can just about fit in the rear outboard pews, but our necks were a bit sore after trying the middle seat. For reference, this writer measures about 186cm.
Leg room was pretty good though, even with the front seats set-up for someone our size, though again, we'd only recommend small children for the middle seat.
Amenities in the rear are sparse, with just a 12-volt socket to charge devices and rear air vents to keep passengers entertained.
The door cards will swallow small bottles, but not much else, while there is no fold down centre armrest or cupholders.
The front fares a little bitter, with larger door pockets, a glove box and central storage cubby, but don't expect to be moving houses in the S3 sedan.
As for the boot, its deep and wide with a cargo net to keep things tumbling round, and is generous enough to swallow 390 litres of volume with the seats in place – that's about 50L more than the Sportback.
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.
Priced at $65,800 before on-road costs, the S3 sedan is about $6500 cheaper than its $72,500 Mercedes-AMG A35 sedan rival, but still comes loaded with what you'd expect in a premium small car.
Close to the end of its life, Audi bundled nearly $9000 worth of extras in the S3 sedan at no extra cost late last year, which includes the aforementioned 19-inch wheels, metallic paint, Nappa leather sports seats, wireless smartphone charger, magnetic suspension, and Bang & Olufsen 13-speaker sound system.
A sports bodykit is also fitted as standard, while LED headlights, keyless entry, push-button start, electronically folding side-view mirrors and heated front seats also feature.
Inside, passengers will find dual-zone climate control, LED interior lighting, flat-bottom steering wheel, and 7.0-inch multimedia system with digital radio, satellite navigation and Bluetooth connectivity.
Our favourite feature though, is the 12.3-inch all-digital virtual cockpit instrument panel, which is easily customisable and clear to read.
Audi set the benchmark for digital displays when it first introduced virtual cockpit in its third-generation TT sports car, and it still remains the benchmark to this day.
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).
Power in the S3 sedan comes from a 2.0-litre turbo-petrol engine, which outputs 213kW at 6500rpm and 380Nm from 1850-5300rpm.
Engine outputs are impressive for a small car, though the powerplant does run out of go when the needle approaches redline.
The engine is also down on power and torque when compared to its newer rivals, such as the 225kW/400Nm Mercedes-AMG A35 sedan and 225kW/450Nm BMW M135i xDrive – though the latter is a hatchback.
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.
Official fuel consumption figures are pegged at 6.5 litres per 100km, while carbon dioxide emissions are 151 grams per kilometre.
The S3 sedan sips premium unleaded fuel and the engine is Euro 6 compliant.
With a 55-litre fuel tank, the S3 should average about 846km of driving range per fill-up, but this is obviously dependent on driving conditions and the urgency of the driver's right foot.
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.
Audi has probably perfected the easy-to-drive-fast formula with its S3 sedan, deftly balancing approachable limits with an engaging drive.
The exhaust just pops, rather than crackles, but again, that characteristic lends itself more to the mature and grown-up status of the S3 rather than the ‘boy racer' image of other cars in the same class.
The quattro all-wheel-drive system means the S3 sedan just grips, but leans towards understeer if you really come into a corner red hot.
It's no bad thing though, as steering is communicative and the chassis feels neutral for the most part.
If you want a small luxury sedan that will make you feel like a hero, the S3 is it.
With peak torque available so early in the rev range, the S3 is also a gem when just cruising around at inner-city speeds and when getting off the line briskly.
The transmission shifts quickly and smoothly, but if you'd prefer, you can always put it in manual mode and shift with the gear stick or steering wheel mounted paddles.
The S3 then, is suitable for pulling double duty as a weekday commuter and weekend canyon carver, and while there are other options that will do each respective thing better, there isn't much out there that can balance both aspects.
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.
ANCAP awarded the entire A3 line-up a full five-star safety rating when it was originally tested in 2013.
We'd love to see something like a surround view-camera added to the next-generation S3, but with its diminutive size, it's not a deal breaker.
Some sort of autonomous self-parking technology would also be appreciated to get the car into those tight spaces.
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.
Audi's S3 sedan, like all new Audis, come with a three year/unlimited kilometre warranty alongside three years of roadside assist and 12 months of anti-corrosion cover.
Service intervals are ever 15,000km or 12 months, whichever comes first.
Both three- and five-year service plans are available for $1850 and $2390 respectively.
