Audi Q8 vs Audi S5

What's the difference?

The updated Audi Q8 60 TFSIe quattro S line still looks good inside and out. It fits a family comfortably without feeling too big and there’s enough here to satisfy those who like the luxury features. 

It's price tag will hurt it but the improved power outputs and driving range is a big plus and makes the plug-in hybrid powertrain make more sense.

The Audi A5 remains a convincing option in the premium mid-size sedan category, even with the near-$10K price increase over its equivalent grade A4 predecessor.

Even in its base spec, it’s a lovely thing to drive and adds enough new kit to be a reasonable option when it comes to value. In terms of tech usability, it stands out from rivals. Practicality is still king for Audi.

But for the heart-over-head types, the S5 is fast and fun while remaining a comfortable cruiser and the price is decent. On a personal note, a six-cylinder wagon? That's a big yes from me.

For the time it’s available, it’s hard to go past the value on offer in the S5 Edition One. Getting an AWD V6 with that kind of capability for under $100K is something that's sure to tempt buyers. If it doesn’t, we need to take a good look at ourselves.

When it comes to style, the Q8 60 TFSIe quattro S line has it in spades. Featuring a design that looks athletic with its long lines and wide stance, you'll always be proud to hop into it.

Red calipers now come standard and they look awesome on the optioned 22-inch alloys. The update sees a redesigned front with new grille and reshaped matrix LED headlights and a 2D badge design.

While SUV coupes aren’t usually my jam, the Q8 manages to tick the 'sexy' box.

The interior is honestly the same and only die-hard fans will notice the new menu screens on the multimedia system. The cabin is a fine example of what a luxury SUV should look like because its polished, well-built and sumptuous but it has the classic Audi edge, so there is still a sporty vibe going on.

The panoramic sunroof adds some airiness to the otherwise dark cabin and the Valcona leather upholstery is liberally splashed about, so most of what you touch feels premium and soft.

The A5 incorporates Audi’s new design language in a way that makes the 2026 model stand out from Audi’s older offerings, but we won’t know how well it works in the family until more new-gen Audi cars arrive.

For now, the A5 is a generally handsome car. It very much looks like an Audi from the front, even a recent A4 if you only very quickly glanced.

The aforementioned S line styling does plenty in making even the base Audi A5 look like a properly luxe thing. There were a few double-checks at the launch to make sure drivers were getting into the right cars.

Fortunately the new car’s designers refrained from busying up the car with trim, the only big features being the side vents at the front.

But even in Avant form the S5 looks athletic, quad-exhausts in the lower bar and the angular rear bodywork moving away from the previously softer, more rounded look Audi had gone with before.

Inside, the changes are arguably more obvious. The A5 is now much more ‘screeny’ than before, especially if optioned with the passenger-side touchscreen.

It’s still decidedly Audi in its layout and design, with geometric shapes on the steering wheel, screen housing, door cards and even on the gear shifter, which is no longer the more traditional handle-type.

The cabin offers plenty of space for passengers and you never feel like you're jostling for elbow room unless there's three adults across the rear seat. Comfort is high with ergonomic seating up front with plenty of adjustment and functions. The rear seat has long bases and the seat backs can recline.

Individual storage leaves a little to be desired for the class and the glove box shoulders most of the burden up front as the middle console is really just a shallow shelf large enough for a wireless charging pad and keys or a chapstick.

Each row gets a couple of cupholders and drink holders, and the rear map pockets round out back-seat storage.

Because of the PHEV powertrain, the 60 TFSIe quattro S line has the smallest boot capacity in the line-up at 505L but this is still more than enough for a decent road trip or grocery haul.

The wide boot aperture, level loading area and powered tailgate add some convenience, as does the 40/20/40 split fold on the rear seats.

Access for each row is solid with wide door openings, low seat positions and 205mm ground clearance. Although, the doors have to been slammed shut for them to close properly and this annoyed everyone in the family. You can spring for a soft-close door feature for $1500 and, honestly, it would be worth it.

The 10.1-inch touchscreen multimedia system is logically laid out and the graphics look great. It has haptic feedback which my husband didn’t love as it made it hard to select things on a bumpy road. You also get built-in sat nav, wireless Apple CarPlay and Android Auto. Other than the occasional lag with the CarPlay connecting upon start up, it's all simple enough to use.

Charging options are good with two USB-C ports in each row and the front also gets a wireless charging pad. The big 12.3-inch digital instrument cluster looks great but it can be annoying to find information on it or personalise it.

…and that gear selector is a bit indicative of the new A5’s interior. It’s now more of a switch that requires a little more attention than the traditional shifter, just like the way the more screen-focused interior requires a little more of your eyeball time than physical buttons.

Don’t get me wrong, as far as screens in modern cars go, Audi seems to have made it as easy as possible to use the new-gen software in the A5. The menus are clear, there are good shortcuts and there’s no lag… but buttons are always better when your focus needs to be on the road.

Fortunately the driver display is nice and clear, it’s a good update on Audi’s ‘Virtual Cockpit’ and you can set it to display important information without looking too busy.

Ergonomically, the way the central screen is angled towards the driver, the centre console layout and the small control panel on the door for lights, mirrors and the like all seem to be well considered and mean you don’t have to awkwardly reach for anything.

There are a few quirks specific to the A5 and S5, one being that if you opt for the panoramic sunroof, it comes with a transparency switch rather than a physical cover, so it doesn’t do much to keep the light out.

It’s also good to note that the passenger screen - again, if optioned - turns to privacy mode when playing media so as to not distract the driver. Pretty handy!

Behind the front row, a regular-sized adult should have enough room to sit comfortably for a decent amount of time without feeling cramped. The light through the sunroof comes in handy here.

Behind that is a 445L boot in Sedan form, or 1299L with the rear seats folded down. As an Avant, the space increases to 448L and 1396L respectively.

The new Audi A5 range starts from $79,900 before on-road costs for the standard A5 Sedan, though the rest of the models available at launch are all S5 variants. A more powerful A5 with 200kW and quattro all-wheel drive will come later, as well as a 270kW plug-in hybrid A5 quattro variant.

For now, the sole A5 in the line-up is well equipped for the price, coming with standard 19-inch alloy wheels, matrix LED headlights with adjustable lighting signatures, keyless entry and digital key via Audi’s app, electric bootlid (or tailgate, given its liftback style) and S line styling as standard.

Interior features include sports seats in real and synthetic leather, heated and electrically adjustable up front, leather steering wheel, tri-zone climate control, a 14.5-inch OLED multimedia touchscreen and 11.9-inch driver display, wireless phone charging as well as wireless Android Auto and Apple CarPlay.

The A5 can be optioned with a Style pack for $3000 which adds 20-inch wheels, tinted glass and black exterior trim. There’s also a Premium pack for $3769 which adds a head-up display, high-power USB ports, a Bang & Olufsen sound system, ambient lighting and front door acoustic window glazing.

The other key variants in the line-up from launch are the S5 Sedan and S5 Avant, coming in at $114,900 and $117,900 respectively. Aside from the more advanced drivetrains, the S5s also gain plenty more features over the A5 including 20-inch Audi Sport alloy wheels, selectable OLED rear lights, tinted windows and more paint colour options.

Inside, Nappa leather-upholstered seats gain cooling and massage functions up front, the steering wheel is heated, and there’s ambient lighting with a ‘dynamic interaction light strip’ that changes colour based on vehicle functions like indicating or changing temperatures.

There’s also a head-up display, high-power USB outlets, a Bang & Olufsen sound system and, perhaps most notably, a 10.9-inch touchscreen for the front passenger as standard. It’s a $1500 option in the A5.

Audi also has a launch variant of the S5, the Edition One, which comes at a lower price and a trim spec closer to the A5, but with the S5’s performance. It has non-adjustable sport suspension, for example, and to score much of the main S5’s kit requires cost-options or option packs.

But the prices are tempting, just $99,900 for the S5 Edition One Sedan or $102,900 for the Avant, $15,000 less than their same-power siblings. For an extra $6000, you can add a head-up display, high-power USB ports and the Bang & Olufsen sound system to the Edition One.

Comparing the entry A5 to the recent entry-level A4, the new A5 wears a price increase of $8000 (the ageing A4 is $71,900), but has more power and a much more modern interior. On price alone it seems a steep jump, but the value is still there compared to rivals. A Mercedes C200 currently starts from $89,900, while a BMW 330i is $92,900.

The Q8 60 TFSI e is AWD and has a 3.0-litre V6 turbo-petrol plug-in hybrid powertrain for a combined power output of 360kW and 700Nm of torque.

The power output has increased by 20kW with the mid-life refresh and that shaves 0.4 seconds off the 0-100km/h sprint time bringing it down to just 5.0 seconds. So it’s a quick and powerful SUV.

The powertrain is paired with an eight-speed automatic transmission which is mostly smooth and the switch between petrol and electric is fairly seamless.

As far as plug-in hybrids go, everything seems to work well here.

The Audi A5 is powered by a four-cylinder turbo-petrol engine which powers the front wheels via a seven-speed dual-clutch automatic transmission. It makes 150kW of power and 340Nm of torque, and should, Audi says, propel the A5 to 100km/h in 7.8 seconds before (eventually) reaching a top speed of 248km/h.

The S5, in all its variants, is powered by a 3.0-litre turbo-petrol V6 which is assisted by a mild hybrid system. It produces 270kW and 550Nm, sending that to all four wheels via a similar seven-speed dual-clutch.

The S5 is much quicker as a result - 100km/h comes along in just 4.5 seconds according to Audi, before reaching a 250km/h top speed.

The mid-life update sees a larger 25.9kWh lithium-ion battery which improves the electric driving range by 27km, bringing it up to 74km overall. This still falls short of its direct rivals but it’s an improvement for efficiency because it’s now more than enough range if you’re just doing the school runs and some errands around town.

The Q8 60 TFSIe has a Type 2 charging port and like most plug-in hybrids, lacks a CCS enhancement, so you have to make do with AC charging options with this one. On a 7.4kW AC charging system you can go from 0-100 per cent in three hours and 45 minutes but if you’re using just a standard house plug port, it will take a few hours more. It's best to leave it overnight.

Audi throws in three charging cables, including a 240-volt domestic charger but you have to pay extra for a wall-mounted box.

The official combined fuel cycle is a low 1.8L/100km and like all plug-ins the best efficiency will be achieved if you charge it often. After charging almost every day and doing a mix of open road and urban driving, my real-world usage has popped out at 7.7L/100km, which isn’t as good as I was hoping but it’s not terrible. I would expect the efficiency to drop on longer trips.

The Q8 likes to drink the good stuff and Audi recommends a minimum 95 RON unleaded petrol to be used for this grade.

Audi claims the A5 uses 6.9 litres of fuel per 100km, which should theoretically deplete the 56-litre fuel tank after 811km of driving. We couldn’t test this on the launch, but reaching claimed fuel efficiency figures remains an elusive challenge.

The S5, according to Audi, comes with an impressive 7.1L/100km figure in Sedan form, or 7.2L/100km as an Avant. That’s 788km and 777km of theoretical driving range if you’re up for a challenge.

The Q8's athletic looks are matched by its on-road handling. The power has a hefty kick that’s effortlessly delivered once you’re up to speed. It did have a few confused moments when I had to accelerate quickly from a full stop - the lower gears didn’t immediately engage and I got a proper bunny hop but it was short lived and for the most part the powertrain delivers the goods.

The adaptive air suspension makes for a comfortable ride despite the massive wheels and you can comfortably cruise around town or the highway without much jostling.

Cabin noise is minimal around town but you get a low hum of road noise at higher speeds. Overall, it's still a refined cabin space to spend a lot of time in.

I do miss hearing some of the engine thrums though because even when the battery is depleted, you don’t get a lot of engine feedback. It certainly adds to the refinement but it loses some of the fun.

The higher driving position feels comfortable and visibility is quite good. Steering is responsive and feels sporty with lane changes but its 13.3m turning circle lets it down in car parks.

The 360-degree view camera system is clear and this has multiple parking sensors. In theory parking should be easy but again, until you get used to that bigger turning circle it can feel clumsy in smaller spaces.

One of the first press cars I ever drove as an even younger lad than I am now was the circa-2017 Audi S4.

Without the perspective of all the many, many cars I've since driven, that S4 blew my mind a little bit with its combination of capability and refinement.

Now, with the context of most of the cars available to the Australian buyer in mind, it’s reassuring to get into this new generation and find that the mid-size Audi torch has been gracefully passed on.

Audi says the new generation, sitting on its new platform, has more focus on balanced driving dynamics, steering precision and steering feel. Without sacrificing comfort, Audi wants the A5 to be a sharper driver’s car.

It might not gel with the Euro tradition of a rear-drive executive sedan given the base A5 is front-wheel drive - the brand of course focusing on its quattro all-wheel drive system - but the A5 is decidedly agile for its size. 

Compared to the S5 especially, as the A5’S 1770kg plays the S5’s 2025kg in Sedan form (2040kg as an Avant). It’s a noticeable weight difference, and it makes the A5 more playful without getting properly ragged.

It also rides on smaller 19-inch wheels and would overall probably make for the better daily driver. Even without the all-wheel-drive traction and extra power the S5 offers, the A5 makes a good case for properly plush commuting. Its 150kW isn’t lacking by any means, and that 340Nm does plenty to help when overtaking.

Its suspension feels well damped, keeping the road’s imperfections out of the cabin without numbing the ride and leaving you without feedback. The steering is similarly direct without being too heavy, making the A5 feel athletic for its size.

But for all the A5’s strengths, there is something undeniable about a six-cylinder European sedan (or wagon). The S5 is heavier, sure, and therefore not as naturally nimble, but it makes up for it. And it’s not just the extra power and mild-hybrid assistance.

It’s a great highway cruiser for a start, but it also adds the confidence of all-wheel drive to a trip, which proved extremely useful on the very rainy winter day we tested it. It holds up well on rough surfaces despite the bigger wheels and extra heft, plus it doesn’t feel out of hand when cornering fast, rolling into a predictable understeer rather than quickly losing traction.

But if you’re in any way conscious of your budget, consider the Edition One. It doesn’t lack any of the key things that make the S5 great, and you get to pocket enough money to buy a second used car.

The A5 and its S5 variants share the same safety features, with the full suite of Audi’s more-than 30 safety and driver assistance systems standard across the line-up.

Physically, the A5 has nine airbags and has been crash-tested by Euro NCAP, the firm awarding it five stars. There's no local ANCAP score as yet.

Some of the key safety features in the A5 and S5 models include a driver attention alert, seatbelt reminders, tyre pressure indicator, adaptive cruise control, lane departure warnings and lane assist, front braking assist, front and rear cross-traffic alert, speed limit sign recognition, surround view cameras and park assist with front and rear parking sensors.

There are also ISOFIX points for fitting child seats to the rear outboard seats.

Audi offers the Q8 60 TFSIe with a five-year/unlimited kilometre warranty and the battery is covered by an eight-year/160,000km warranty which are all pretty standard terms compared to its rivals.

There is a standard five-year servicing package that costs $3570 and servicing intervals are spaced at every 12 months or 15,000km, whichever occurs first. However, if you purchase the Audi Advantage Package you add a further two years of coverage to the warranty, roadside assistance and servicing, which is pretty good for the class.

Audi’s five-year/unlimited kilometre warranty is starting to fall behind the industry standard, though is about normal for a premium brand. On top of this, customers can opt to purchase extra years of warranty up to a maximum nine years which costs $3590.

Audi does also offer 12 years of bodywork manufacturing warranty against corrosion or perforation. There’s also five years of Audi roadside assistance.

Servicing intervals for the A5 come in at every 15,000km or 12 months, with customers able to purchase fixed-price servicing plans at a discount compared to paying per service.

A five-year servicing pack for the A5 Sedan is $3360, and for the S5 it’s priced at $3540.
