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.
You might call it six degrees of Kombi separation. Somewhere, somehow just about all of us have a VW bus lurking in our family and friends' back story. And this is the latest version of that familiar box on wheels to hit the Aussie market.
It’s the premium, sportier, AWD GTX version of the pure-electric Volkswagen ID.Buzz.
This one-box wonder hits the retro-futurist ball out of the park and we attended its local launch to explore whether what’s under the skin supports the promise of its stunning exterior.
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 only way to make this car cooler would be to add a split fold-out windscreen and a tube steel luggage rack on the roof.
It’s fast, super practical, comfortable and guaranteed to put a smile on the face of premium family buyers ready to go for something different. And that smile will extend to just about everyone who lays eyes on it. I love it.
Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.
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.
The ID.Buzz GTX is characterised by a unique front bumper with new integrated daytime running lights near its outer edges and a narrower black honeycomb grille.
GTX badging and the exterior mirror housings are finished in high-gloss black, and 21-inch alloy wheels are standard.
The rich ‘Cherry Red’ solid paint finish of the launch test car is exclusive to the GTX and it’s a fair bet many buyers will stump up the extra $4K required for a two-tone treatment, in this case with ‘Mono Silver’ as the highlight colour.
The interior is familiar ID.Buzz territory, with the long, broad dashtop pushing the windscreen and small front windows beside it into a quintessentially Kombi ‘bay window’-style design.
A 12-inch central multimedia screen sits proud of the multi-layered dash, and a slick 5.3-inch LCD instrument and car data display is fixed in front of the driver.
A black headliner dials up the sporty feel, the electric front seats are a GTX-specific design and the synthetic diamond pattern microfleece trim is highlighted by red contrast stitching and piping.
The red cross-stitching extends to the steering wheel and smile-inducing stainless steel ‘play’ and ‘pause’ symbols on the accelerator and brake pedals are retained.
The sub-zero cool exterior design manages to merge with a more restrained and practical interior perfectly. VW has solid retro form with the ‘New Beetle’ from the 1990s and this primo ID.Buzz looks amazing. It drew an instant crowd of curious onlookers every time we stopped.
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 ID.Buzz GTX is offered in shorter wheelbase variants with five- and six-seat configurations for other markets, but here it’s seven seats and long-wheelbase only.
At close to five metres long and just under two metres wide, it’s road-trip ready with heaps of breathing room for all seven occupants.
Placement of the gearshift on the right-hand side of the steering column frees up extra space in the front and there’s heaps of storage including a moveable (and removable) centre console unit between the front seats with pull-out drawers at either end, two trays in each door (the lower one offering room for multiple large bottles), a decent glove box and a fold-out dual cupholder unit.
There’s also an oddments shelf in front of the passenger, a wireless device charging slot in the dash and adjustable fold-down armrests on both sides of the front seats.
Pull the handle on the power-opening sliding side doors and the second row opens up with three seating positions offering hectares of room in all directions.
This row can be moved 200mm longitudinally if a turf war erupts with those in the third row. And storage is great with two pockets and a fold out table on each front seatback as well as huge door bins with waste baskets included. There are also adjustable vents with temperature control in the roof.
There’s enough head and legroom for adults in the third row although the backrest is relatively upright. Even access is straightforward and there are numerous storage trays, cupholders, air vents and storage slots back there.
Power across the cabin runs to two USB-C ports in the dash, another in the front passenger area and four USB-C charging sockets in the rear.
Boot space increases from a handy 306 litres with all seats up to 1340 litres with the 50/50 split-folding third row down, and 2469L with it and the 60/40 split second row lowered. That’s plenty.
And that 1.6-tonne braked trailer towing capacity means a jet ski, even a mid-size camper trailer, is within hauling range.
The power tailgate is welcome and the rear of the boot’s load platform sits above two storage boxes. But you won’t find a spare of any description back there; a repair-inflator kit is your only option. So beware, a flat could really suck the air out of this mobile family room.
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 new ID.Buzz GTX 4Motion is priced at $109,990, before on-road costs, which puts it in the same price zone as a diverse range of large, primo people haulers.
On price, it competes with three-row EVs like the Kia EV9, LDV Mifa 9, and if you stretch the price equation a little further, the Zeekr 009. But in terms of style and personality, this machine lives in a world of its own.
Maybe its VW California Beach sibling comes closest, however that van’s traditional turbo-diesel powertrain stands in stark contrast to the ID.Buzz’s pure-electric vibe.
Once you’ve crested the $100K mark, it’s fair to expect a healthy list of included features and the ID.Buzz GTX doesn’t disappoint.
Aside from the performance and safety tech we’ll get to shortly, the highlights include adaptive cruise control, auto LED matrix headlights, 13-speaker (plus sub-woofer) Harman Kardon audio with digital radio, wireless Android Auto and Apple CarPlay, three-zone climate control, a panoramic (dimmable) glass roof, 30-colour ambient lighting, power-adjustable heated front seats, heated (outer) rear seats and 21-inch alloy rims.
There’s also a head-up display, a heated steering wheel, rain-sensing wipers, microfleece seat trim, keyless entry and start, electric side doors and tailgate (the latter with hands-free functionality), ‘Ask IDA’ voice control and dark tinted windows.
That’s a strong, class-competitive value equation. Metallic or pearl effect paint will set you back $1890, the two-tone treatment is $4090 and black 21-inch alloys add $380.
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.
The GTX is a twin-motor AWD, the front unit generating 80kW/134Nm and the rear 210kW/560Nm. Total output is 250kW/590Nm which boosts towing capacity from 1.0-tonne in the single-motor ID.Buzz to 1600kg.
A single-speed transmission sends drive primarily to the rear wheels to maximise efficiency, the dual-motor set-up able to direct power to the front axle as required during acceleration or to manage available traction.
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.
The ID.Buzz GTX’s 86kWh lithium-ion battery delivers a claimed (WLTP) range of 473km and the car uses a CCS Type 3 socket. VW includes a Mode 2 and Mode 3 cable as standard.
The claimed 10-80 per cent 200kW DC fast charge time is 26 minutes, while the same top-up takes nine hours at a maximum 11.0kW AC capacity.
Claimed energy consumption on the combined (urban/extra-urban) cycle is 20.2kWh/100km (WLTP) and over several hundred kilometres of mainly B-road and freeway running on the launch we saw an average of 24.5kWh/100km, which isn’t out of order given the type of driving involved.
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.
Despite the fact that it weighs in at around 2.8 tonnes (2780kg), Volkswagen Australia says this dual-motor ID.Buzz accelerates from 0-100km/h in 6.4 seconds and on to a 160km/h maximum velocity, if you dare.
And there is always some serious oomph lurking under your right foot. Trundle along at 65km/h, pin the accelerator, and in roughly two blinks of an eye you’re doing 95km/h.
Proportionally, this car is like a loaf of bread on wheels - about as high as it is wide. And on the windy launch drive we were buffeted a bit, the car moving sideways slightly when hit with a gust. But overall, it remains stable despite its proportions. That said, some wind noise comes over the bluff nose on the freeway, but never to an alarming degree.
The ID. Buzz rides on VW’s Modular Electric Drive (MEB) platform and there’s been past criticism of the short-wheelbase versions' ride quality, but there are no such issues here.
Suspension is by struts at the front and semi-trailing arms at the rear and this GTX has had a suspension retune with particular attention paid to key components, including the dampers.
On rural roads that have seen better days, dotted with potholes, bumps and thumps, a combination of that suspension retune and the longer wheelbase helped the GTX handle it well.
There are five drive modes with Comfort the default. Eco smooths out acceleration, tapers the climate control and reduces overall power, while Sport dials up the powertrain, suspension and steering. Traction optimises the AWD system for loose or slippery surfaces and Individual allows you to cherry pick various attributes for a custom set-up.
Steering is progressive rate and you can feel it loading up nicely as you head into a corner. Not the last word in terms of road feel, but the car points accurately and turn-in is nice and progressive.
At the same time you’ve got the electric motors constantly shuffling drive between the front and rear axles, helping you out if you decide to explore the car’s sporty nature and have a crack in the corners.
Tyres are Hankook Ventus S1 Evo3 EV specials (235/45 fr - 265/40 rr) and in long, sweeping bends, taken at pretty decent speed, they grip hard. Even on coarse-chip B-road surfaces there’s a bit of rumble but it’s far from a roar.
Braking is by large (358mm) ventilated discs in the front and, believe it or not, drums at the back. A well-designed, modern drum brake can work effectively and the regenerative braking in an EV like this is a big factor in terms of washing off speed.
In terms of lower speed manoeuvres, you’ve got a 360-degree camera view as well as a reversing camera and front and rear parking sensors. If you really need some help, Park Assist Plus will get the job done for you.
In terms of ergonomics, we spent hours behind the wheel and the front seats remained comfortable and supportive in terms of lateral grip.
Speaking of grip, the steering wheel is nice to hold. And the cool little 5.3-inch instrument and car data display is clear as a bell, and the large 12-inch media screen is easy to use and working through the different screens is largely intuitive.
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 current ID. Buzz range hasn’t been assessed by ANCAP although its sister organisation, Euro NCAP, awarded it a maximum five-star rating in 2022.
As you’d expect, a full suite of driver-assistance tech is onboard including highway-speed AEB with pedestrian and cyclist monitoring, adaptive cruise, lane-keeping assist, lane-change assist, blind-spot monitoring, rear cross-traffic alert, driver fatigue monitoring and tyre pressure monitoring.
There’s also a 360-degree view and reversing camera, plus Park Distance Control incorporating front and rear proximity sensors.
The airbag count runs to seven - front, front side, curtains covering the second and third rows, as well as a front centre bag. And multi-collision brake minimises the chances of subsequent impacts after an initial crash
There are five top tethers for child restraints; three across the second row and two in the back row, with four ISOFIX anchors across both rows.
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 ID.Buzz GTX is covered by Volkswagen Australia’s five-year/unlimited-km warranty with two years’ roadside assistance included. On top of that, there’s an eight-year/160,000km warranty on the drive battery.
That general warranty is in line with the mainstream market, although it’s worth noting an increasing number are stepping up to longer terms, including 10 years.
There’s a 12-year corrosion perforation warranty and keep servicing with an authorised VW dealer and that roadside assistance support will be rolled over for another two years each time.
The recommended maintenance interval is two years/30,000km. Standard scheduled service pricing is $687 for each of the first five workshop visits, while pre-paid plans covering six, eight or 10 years represent savings of between 30 and 35 per cent on that figure, which is pretty handy.
