What's the difference?
Audi would probably prefer you not to realise this, but the five distinct versions of S4 and S5 on the market all pertain to a single performance and equipment formula spread across five different bodystyles.
Yes five, and this has been the case for more than a decade, with the S4 sedan and Avant wagon, A5 two-door Coupe, convertible Cabriolet and five door liftback Sportback all representing vastly different shapes for you to choose from, with the same underpinnings. This simply echoes the A4 and A5 ranges they’re based on of course, and BMW clearly thought it was a good idea too, given the 3 and 4 Series ranges were split into individual lines at the start of last generation.
Mercedes-Benz offers a similar array, minus the liftback, but is happy to wrap the whole lot under the C-Class label.
So, given that the A4 and A5 range scored a mid-life update a few months ago, it’s only logical that the changes flow on to the performance S4 and S5s, with the top-tier RS4 Avant following suit.
We’ve covered the latter in October, and now it’s the turn for the former, and CarsGuide was among the first to drive the updated S4 and S5 ranges at their Australian media launch last week.
If the Acadia had an accent it would be a southern drawl because this big seven-seat SUV is built in Tennessee, USA, and wears a GMC badge when it’s at home.
In Australia of course it wears a Holden one and comes straight from the factory in right-hand drive. So how does it suit Aussie conditions? Does it even know the importance of a sausage on a piece of bread bought outside a hardware store on a Saturday?
All this and more was learnt when the entry grade LT front-wheel drive came to live with my family.
The S4 and S5 range continues to represent a great formula for performance you can live with every day. They're arguably the sweetest balance Audi produces, actually. All come fantastically equipped, with cabins that feel truly special, and we’re lucky they can be had in a choice of five bodystyles.
The Holden Acadia is a proper seven-seater SUV in that it will fit adults in the third row without turning your friends into enemies. It’s also practical and well fitted out with storage places and utilities such as USB ports.
I was particularly impressed with the advanced safety equipment on-board even at this entry LT level. Yes, it’s a V6 petrol and it’s not the most fuel-efficient SUV, but our time with it showed that with cylinder deactivation and the stop-start system it might not be as thirsty as you’d think.
The S4 sedan and Avant have scored the bulk of design updates, with all new and recontoured side panels including the sedan’s C-pillar matching what was applied to the A4 earlier this year.
This is paired with new front and rear facias and lighting for a subtle but extensive rework of the fifth-generation S4’s conservative look.
The S5 Sportback, Coupe and Cabriolet get S5-specific new lighting and facias, but no sheetmetal changes. As before, the Coupe and Cabriolet ride on a 60mm shorter wheelbase than the Sportback, sedan and Avant.
The S5s also get Matrix LED headlights as standard which do a neat animated sequence when you unlock the car.
Other visual hallmarks include new S4-specific 19-inch wheels, with S5 stepping up to its own unique 20-inch wheel. The six-piston front brake calipers are appropriately painted red, and there’s S-specific adaptive dampers under there too. All variants aside from the Cabriolet get a lip spoiler on the rear.
On the inside, there’s a new centre console and bigger 10.1-inch multimedia screen, while the Audi Virtual Cockpit driver instrument display now offers a hockey stick-style rev counter in additional to traditional dial layouts.
To fully understand the look of the Acadia, take a peek at the GMC website - but make sure you shield your eyes in the same way you would during a solar eclipse, or when welding, or in an atomic blast.
You’ll understand when you get there but suffice it to say contained within the site are some pretty confronting trucks and SUVs. Once you’ve recovered, you’ll realise the Acadia is the supermodel of the GMC family.
Yep, it has a big, blocky, truck-like look but it’s a refreshingly tough styling alternative to more elegant looking SUVs such as the Mazda CX-9.
The Acadia is also one of the smallest members of the GMC family, yet its dimensions position it as a large SUV in Australia. Even then it’s not huge compared to other large SUVs here, so you won’t have an issue piloting it in Aussie car parks or fitting into spaces.
The Acadia measures 4979mm end-to-end, 2139mm across (with the mirrors out) and 1762mm tall.
Along with the Mazda CX-9 the Acadia would also consider the Kia Sorento and Nissan Pathfinder to be among its rivals.
Inside, the Acadia is a modern and stylish looking place, although it’s a bit unrefined. Still, as one YouTube commenter reminded me parents will like the wipe clean surfaces.
Well her comment wasn’t written that politely but being a parent, I concur that the hard plastics have that advantage.
The interior is not all unrefined. The seats, even in the entry grade LT we tested, while cloth (and only available in Jet Black) are sculptured with bolsters and finished with a textured pattern that looks and feels great.
The biggest practicality change among the five S4 and S5 variants is their upgrade to the latest version of Audi’s MMI multimedia system, which steps up to a 10.1-inch touchscreen and drops the scroll wheel from the centre console.
It also boasts ten times the computing power of the version it replaces and uses this and an on-board sim card to access Google Earth maps for navigation and Audi Connect Plus that offers driver information such as fuel prices and parking information as well as point of interest search and weather information, plus the ability to make emergency calls and seek roadside assistance.
There’s also a wireless phone charger, but using Apple CarPlay will still require a cord as per Android Auto.
I only drove the S4 Avant and S5 Sportback at their media launch, which are clearly the most practical of the five, but from our experience with the previous versions, each looks after its occupants well in terms of space and storage. Back seat accommodation is clearly not a priority in the Coupe and Cabriolet, but there’s three other variants if that’s what you’re looking for.
The Cabriolet can open its automatic folding soft top within 15 seconds, at speeds of up to 50 km/h.
The Acadia’s practicality game is strong. It boasts seven seats with third row positions actually able to fit adults, five USB ports sprinkled through the cabin, and a cargo capacity of 1042 litres with the third-row seats folded flat and 292 litres with them in place. If you have three kids, even teenagers, the Acadia could be the perfect family personnel carrier for you.
All three rows are spacious and even at 191cm tall I had good shoulder and elbow room up front, and in the second and third rows I had enough legroom to sit in each seat behind my seating position without feeling cramped.
Feeling a bit down because you might not be able to stretch the budget to get the LTZ-V? Well, cheer up – the LT has more headroom and that’s because it doesn’t get the sunroof which eats into the ceiling height.
Cabin storage is excellent. There’s a wide and deep centre console bin, a hidey hole in front of the shifter, a tray for second row passengers, six cup holders (two in each row) and decent-sized door pockets.
Directional air vents for everybody on board, three-zone climate control, two 12-volt power outlets, privacy glass and proximity unlocking complete a great practicality package.
As I mentioned above, the S4 and S5 line-up are in many ways the same, but also different, and these differences result in a price span of $20,500 between the S4 sedan and the S5 Cabriolet.
The former is now $400 cheaper with a list price of $99,500, with the also-$400 cheaper S4 Avant not far beyond at $102,000.
The S5 Sportback and Coupe are now $600 more expensive at an equal list price of $106,500, while the swish folding soft top of the S5 Cabriolet pushes it up to $120,000 (+$1060).
Equipment levels are consistent across all five variants aside from the S5s getting Matrix LED headlights as standard and one inch larger 20-inch wheels.
Key details include Nappa leather trim with front sport seats with seat heaters and massage function, a Bang & Olufsen sound system which spreads 755W across a total of 19 speakers, brushed aluminium inlays, head-up display, coloured ambient lighting, tinted windows and metallic paint.
Over the past 12 months, the S5 Sportback has proven to be the most popular of the five variants by far, accounting for 53 per cent of sales, with the S4 Avant next in line at 20 per cent, the S4 sedan making up 10 per cent, and the S5 Coupe and Cabriolet combining to make up the remaining 17 per cent.
The front-wheel drive Acadia LT lists for $43,490, which is $4500 less than the all-wheel drive version.
The standard features list includes 18-inch alloy wheels, roof rails, LED running lights, three-zone climate control, proximity key, rear parking sensors, Bluetooth connectivity, six-speaker stereo, 8.0-inch screen with Apple CarPlay and Android Auto, noise cancellation, dual chrome exhaust tips, privacy glass and cloth seats.
The value is pretty darn good here and you’re not missing out on much by not stepping up to the $10K more LTZ grade, apart from wireless charging, and power and heated leather front seats.
The Acadia costs about the same as the Pathfinder ST but is better value; about $500 more than the entry grade Kia Sorento Si; but undercuts Mazda’s CX-9 Sport by about $3K.
Audi has taken an ‘if it ain’t broke’ approach with the mechanicals, with all S4 and S5 models unchanged with this update. So the centrepiece continues to be the single-turbocharged 3.0-litre V6 that produces 260kW and 500Nm, with the latter available from a broad 1370-4500rpm.
The rest of the drivetrain is also unchanged, with the venerable but excellent ZF eight-speed torque converter auto paired with the Quattro all-wheel drive system that can send up to 85 per cent of drive to the rear wheels.
All Acadias come with a 3.6-litre V6 petrol engine which makes big dollops of power and torque or 231kW (at 6600rpm) and 367Nm (at 5000rpm).
A nine-speed automatic swaps gears, and in the case of our two-wheel drive LT test car the drive went to the front wheels only.
The V6 gets the thumbs up for its stop-start fuel saving system and cylinder deactivation, plus good acceleration and the smooth power delivery you’d associate with a naturally aspirated engine, but a thumbs down for needing to rev hard to make that mumbo.
Official combined fuel figures range from 8.6L1/00km for the S4 sedan to 8.8L/100km for the Avant, Coupe and Sportback, while the heavier Cabriolet steps up to 9.1L/100km.
All are pretty good considering their performance potential and the size of these cars, plus the fact that they only require 95 RON Premium Unleaded fuel.
All have a 58-litre fuel tank, which should enable a range of at least 637km between fills based on the Cabriolet’s figure.
We were surprised by the Acadia’s fuel efficiency. After filling up the tank I drove for 136.9km on a combination of hilly country roads and peak hour evening city traffic and then filled up again – only 13.98 litres were used. That’s a mileage of 10.2L/100km. The official combined consumption figure is 8.9L/100km.
So, while the engine is big and not particularly new (it’s an evolution of the V6 built by Holden in Australia for the Commodore) it does have fuel-saving tech like cylinder deactivation and a stop-start system – which you can’t switch off.
Still, not the most fuel-efficient seven-seater – those with turbos and smaller capacity engines such as Mazda CX-9 are truly amazing in the way they can deliver grunt without getting thirsty.
The S4 and S5 range were already an excellent balance between everyday comfort and a genuine sporting edge, and nothing has changed with this update.
I spent time behind the wheel of the S4 Avant and S5 Sportback at their media launch, and both managed to deliver the proper Audi luxury experience over some pretty rough rural roads, while always feeling a bit more sporting than a regular A4 or A5. That’s with the Drive Select left in the default mode, but you can shift that sporting personality up a few notches (while scaling back the comfort), by selecting Dynamic mode.
My preferred means of adjusting their personality is by simply tugging the transmission selector back to activate S mode, which livens up the engine and transmission without stiffening up the suspension.
Across the five S4 and S5 bodystyles, there is some variance in performance potential, with the S4 sedan and S5 Coupe topping the performance chart with 0-100km/h boasts of 4.7s, with the S5 Sportback trailing them by 0.1s, the S4 Avant by a further 0.1s and the Cabriolet managing a still-fast 5.1s claim.
Another area I consider the S4 and S5s to get just right is their exhaust note. It is adaptive, but there’s nothing synthetic about it, and the generally muted and distinctly V6 burble is always there to remind you that you’re aboard a proper performance model, but not in such a way that it will annoy you, or your neighbours. Polite performance, if you will.
I drove the Holden Acadia back-to-back with the Nissan Pathfinder – you can watch the model comparison in the video above, but the upshot of that experience was important.
See, while I wasn’t a major fan of the Acadia driving experience when I first met the SUV at its Australian launch in 2018, when I drove it straight after the Pathfinder the difference was like night and day.
The Acadia is comfortable, from the big seats to the smooth ride. If you’re covering a stack of territory the Acadia makes a great highways cruiser and will chomp up big distances effortlessly.
That V6 does need to rev hard, but it’s powerful and acceleration is swift, while the nine-speed automatic shifts pretty seamlessly. Noise cancelling tech keeps the cabin fairly serene, too.
Look, it’s not the most dynamic of SUVs and there was a bit of tyre chirp in the corners when pushed, but this isn’t a performance car and nor is it trying to be.
Small windows mean a cooler, tough look, but the downside is a dark cabin and occasionally visibility is limited by the A-pillars or out the rear windows.
A 2000kg braked towing capacity will rule the Acadia out for many thinking of pulling a large caravan or big boat. The Pathfinder’s 2700kg braked towing capacity is a strength of that SUV.
Do you need all-wheel drive? Nope, but it’s handy for dirt and gravel roads. Still the 198mm ground clearance with only front-wheel drive should see you get down bumpy roads that regular sedans couldn’t handle.
All S4 and S5 variants boast an impressive array of safety features, but there’s some interesting points when it comes to ANCAP ratings. Only four cylinder A4 models (therefore not S4) were given a maximum five star rating when tested according to less stringent 2015 standards, but all A5 variants (therefore S5) aside from the Cabriolet carry a five star rating based on the tests applied to the A4. So officially, the S4 is not rated, but the S5 Coupe and Sportback are, but based on the A4 rating that doesn’t apply to the S4. As with most convertibles, the Cabriolet is simply not rated.
The airbag count totals eight in the sedan, Avant and Sportback, with dual front airbags, plus side and curtain airbags covering front and rear.
The Coupe drops the rear side airbags, while the Cabriolet also drops curtain airbags, meaning there’s no airbags for rear seat occupants. The roof is made of folding fabric, there has to be some safety compromise.
Other safety features include front AEB that works up to 85km/h, adaptive cruise control with traffic jam assist, active lane guidance and collision avoidance assist that can automatically swerve, a 360 degree camera system, rear cross-traffic alerts, exit warning that can prevent you opening a door into an oncoming car or cyclist, and pre sense rear that can detect an impending collision from behind and prepare the seatbelts and windows for maximum protection.
The Acadia was given a maximum five-star ANCAP rating when it was tested in 2018 and even the entry-level LT we tested is equipped with an outstanding amount of advanced safety equipment.
Standard on the LT is AEB with pedestrian and cyclist detection, lane keeping assistance with lane departure warning, lateral impact avoidance, blind spot monitoring, rear cross traffic alert, adaptive cruise control, traffic sign recognition, rear seat passenger reminder and airbags which extend all the way to cover the third row.
Now, you should know the driver’s seat vibrates if your parking sensors detect you coming close to an object. Yup, it’s weird. If that’s not your thing you can go into the screen’s menu and change that to an audible ‘beep’. I’m more a ‘beep’ kind of driver.
A space-saver spare wheel is under the boot floor and I’d advise you to familiarise yourself with how to access it (it’s a bit tricky) in daylight before (or if ever) you’ll need to use it for real.
Audi continues to offer a three year, unlimited kilometre warranty, which is in line with BMW but lags behind the five years offered by Mercedes-Benz these days. This also contrasts with the five year norm among mainstream brands, which is punctuated by the seven year warranties of Kia and SsangYong.
Service intervals are a convenient 12 months/15,000km though, and the same five year ‘Audi Genuine Care Service Plan’ offers capped price servicing for the same $2950 total over five years applies to all S4 and S5 variants. This is only marginally more than the plans offered for regular petrol A4 and A5 variants, so you’re not being stung for the thoroughbred versions.
The Acadia is covered by Holden’s five year/unlimited kilometre warranty.
Servicing is recommended every 12 months or 12,000km. Expect to pay $259 for the first service, $299 for the second, $259 for the third, $359 for the fourth and $359 again for the fifth.
