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.
It's inevitable that Audi's S5 will spend the bulk of its time pouncing between traffic lights in Australia's clogged and cramped CBDs, but it's hard to imagine a better place to enjoy the hard-charging antics of this stunning Coupe than the sublime twists and turns of Tasmania's perfect blacktop.
Based on the also-very-pretty A5 Coupe, the S-stamped version adds a powerful 3.0-litre V6 engine, a quick-shifting eight-speed gearbox and some suspension trickery that glues the sleek Audi to the road surface below.
It's the fastest, most powerful and lightest S5 to date, and it's cheaper than the car it replaces to boot. And better still, we had an entire island neatly wrapped in perfect ribbons of tarmac to put it to the test.
The second-generation version of the S5 Sportback is set to appear in May, while the new S5 Cabriolet will follow later this year. For now, the two-door Coupe will lead the charge.
|Fuel Type||Premium Unleaded Petrol|
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.

The kind of car that pushes back the autonomous argument, the S5 Coupe is a fun and frantic blast from the behind the wheel. Addictively powerful, sharp to steer and with the kind of endless grip that turns a twisting road into your own personal amusement park, the S5 injects a ton of fun into back-country blasts. It might be a touch uncomfortable in the city, but that's a price we're willing to pay.
Does a V6 turbo Audi S5 trump the previous V8 version? 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.
Undoubtedly one of the better looking cars on the road today, the Audi S5 Coupe looks sleek and stunning from every angle.
Viewed front-on, the newly designed single-frame grill (it's now wider and flatter) looks slick and powerful, while a raised bulge in the bonnet (Audi calls it a power dome) hints at the performance lurking beneath it.
Side on, a body crease (so sharp it's like it's been cut with a laser) runs the length of the body, while the 19-inch wheels are perched at the furthest corners. Four burbling exhausts emerging from beneath the boot complete this perfectly painted picture of intent.
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.
Well, the hint is right there in the name. This might be a touch over 4.6m long, but that swooping coupe roofline eats away at your practicality, especially for rear seat passengers.
Up front, though, it's spacious and comfortable and built for purpose, with terrifically bolstered sports seats and a flat-bottomed steering wheel that's among the best in the business.
Shift to the back, and you'll find two seats (the middle one has been replaced by a weird plastic table), but there is plenty of legroom. Headroom, on the other hand, is a less positive story, with anyone who is 183cm (six-foot) or taller are sure to become well accustomed with the S5's roof lining.
There's a cupholder in each of the rear doors, matching the two for front seat passengers, and two ISOFIX attachment points in the back row. Backseat riders also get their own air-con controls, and a power outlet.
Boot space is what Audi claims is a class-leading 465 litres (up 10 on the outgoing car) and the rear seat is split 40/20/40.
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.
Audi's new S5 Coupe arrives with a sticker price of $105,800, which is a touch over its most obvious competitor - the marginally slower BMW 440i Coupe.
The good news, though, is that you'll want for little, and can easily avoid Audi's infamous options list. Expect 19-inch alloy wheels that display the bright red brake calipers, illuminated door sill trims, nappa leather sports seats that are heated in the front, and offer pneumatic bolster and lumbar support, plus carbon detailing in the interior.
In-cabin technology is taken care of via Audi's awesome 'Virtual Cockpit' (a huge digital screen that replaces the traditional dials in the driver's binnacle - the Google Earth-overlayed navigation is particularly outstanding) along with a second, centred screen that feeds a 10-speaker stereo.
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).
The S5 Coupe's engine is an absolute peach, with a thick and steady flow of power that can make you forget a V8 version ever existed.
The turbocharged, 3.0-litre V6 is good for 260kW at 5400rpm and 500Nm from 1370rpm, channelled through a sensational eight-speed automatic gearbox and on to all four wheels. It's enough for a 4.7sec zero to 100km/h time and a limited top speed of 250km/h. But the sprint is only half the story, with the engine's mid-gear acceleration offering an insanely addictive rush of power when overtaking.
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.
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.
Addictive. The power delivery from that S5's V6 is rich and constant, and there's useable urge lurking all over the rev range. The sprint from 0-100km/h is enticing enough, but it's the way the car climbs from 90km/h, 100km/h or 110km/h when you plant your foot, a surging wave of power kicking you in the base of the spine as the S5 Coupe blasts you into the future.
The steering tune is bespoke to the S5, and it's the only model in the A5 range that arrives with adaptive dampers as standard fit, allowing you to dial firmness into the suspension, as well as tightening up the steering, gearing and throttle response.
As a result, it is an absolute joy to pilot through bends, sitting low and flat throughout before making use of its all-wheel drive to hurtle out the other side. It's the stuff involuntary smiles are made of, and you're unlikely to ever tire of it.
For day-to-day use, however, it sits just on the firm side of comfortable, which might grate on pockmarked city road surfaces, but the engine, exhaust and steering weight are all muted enough to ensure it can double as a quiet and composed commuter.
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.
Audi has thrown just about everything it's got at the S5 Coupe, and the safety list is extensive. Expect six airbags (dual front, side and curtain), which join a reversing camera, parking sensors, forward collision warning with AEB and pedestrian detection, a rear-impact sensor, cross-path assist and a driver fatigue detection system.
The entire A5 range was awarded the maximum five star ANCAP safety rating.
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.
