Audi S5 vs Mercedes-Benz Eqe300

What's the difference?

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.

The Mercedes-AMG EQE53 SUV has some serious tech inside and will fit the family in style. If you're after the AMG experience, you may be a little disappointed as this model leans heavily towards plush rather than sports-SUV. And it does plush extremely well but it begs the question whether the AMG factor is worth the extra cash.

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.

We affectionately nicknamed our test EQE53 model the Blue Tic Tac because of its… well, similarity to the mint.

While not uncommon in the EV market, the EQEs pillowy design doesn't exactly scream 'big personality'. However, it does feature some cool features like the massive 22-inch alloy wheels, red brake calipers and the AMG badging at the rear. But that's all that separates it from its non-AMG siblings.

Head inside and it features all of the plush comforts and styling you’d expect from a Merc with some of the best ambient lighting in the business and a sunroof that manages to make the cabin feel airy despite all the black trims. 

Some of those trims, like the synthetic grey panels scattered liberally throughout the cabin, are found in all EQE models and don't reflect the grade level. A trim with better tactility and style would be a point of difference.

The dashboard features three screens in a ginormous panel, which surprisingly doesn’t catch the light but does show fingerprints and every spec of dust on it. Which might annoy you as it's 100 per cent the drawcard for the interior and when it's dirty, it's very obvious.

Although I'm not in love with some design choices, it's still a lovely cabin to spend time in.

…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 cabin of the EQE53 offers plenty of head- and legroom for its occupants. Using the armrests is also a civilised affair as there's not fighting for elbow positions!

Access to both rows is (annoyingly) more complicated than it needs to be because of the sidesteps - which are, quite frankly, useless on a car like the EQE. They hit your shins/calves when you're not using them and using them feels silly.

All seats offer a tremendous amount of comfort but the fronts benefit from heat and ventilation functions that keep you relaxed year-round. They extend everywhere you need them to to get into the best seating position.

Storage is excellent throughout the car and in the front there's an extra-deep middle console (it swallows most of my arm), a large centre console that features retractable cupholders and a big shelf underneath for bulky items, like a handbag, or as my mum joked, Saturday night’s takeout and a bottle of wine!

Each door pocket gets a dedicated bottle holder and the rear also gets two retractable cupholders and a pair of map pockets.

The boot has 520L of capacity available which is a good size for the class and the wide boot aperture and level loading space make it easy to slide things in and out. You miss out on underfloor storage in the EQE53 model but the back seat has a 40/20/40 split to open up storage options.

The technology looks daunting but is very user-friendly once you spend some time with it. The main multimedia system is responsive and you can access the menus from the steering wheel controls as well as the touchscreen.

The system has wireless Apple CarPlay and Android Auto and satellite navigation, all of which are easy to use. Charging is good with eight USB-C ports (six up front!) and a wireless charging pad.

Despite having four co-pilots this week, the additional screen in front of the passenger remained mostly unused and ended up being more of a novelty.

The real bugbear has been the air-conditioning system. Despite having a pre-climate function, it takes ages for the car to cool down and my eight-year old struggled in the rear the most. The rear vents just don't seem to pump much out, even on the top speed setting.

Once the system has cooled the cabin, though, it's like a fridge. But until it does... you really notice the 30+ degree days!

The EQE SUV is available in three grade levels and the EQE53 model on test for this review here is the creme de la creme, tucking in under AMG badging, and all that implies. Sitting at $191,900, before option packs or on-road costs, positions the top model in between its high-performing electric rivals, the Audi SQ8 e-tron at $173,090 MSRP and the BMW iX M60 at $228,400 MSRP.

Our test model has the optional 'AMG Dynamic Plus Package', which adds $5691.40 to the price tag but includes a bunch of features AMG-lovers will appreciate. Items like an 'AMG Sound Experience' which gives you three motor soundscapes to choose from, a track pace function, improved motor outputs and a boosted top speed of up to 240km/h.

In terms of technology, the not-so-standard fare includes a seriously cool-looking multimedia display consisting of a 3D Burmester surround sound system and three digital screens covering the width of the dash.

The tech is rounded out by wireless Apple CarPlay and Android Auto, satellite navigation, four-zone climate control, eight USB-C ports, a wireless charging pad and digital radio.

The top model also gets some luxuries like heated and ventilated front seats featuring a three-position memory function, electrically extendable under-thigh support and a 'kinetic' function (think light stretching rather than massage).

The upholstery and trims are a good mix of black Nappa leather on the seats and doors (partial), as well as synthetic suede-like materials on accent panels throughout the car.

Practical items include a hands-free powered tailgate, rain-sensing wipers, keyless entry/start, pre-entry climate, dusk-sensing headlights and a park assist function to help in tricky car spots.

Overall, the EQE53 is fairly well packaged but does miss out on a few luxury extras in the second row, which is noticeable because its rivals cover this area a little better.

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 EQE53 is an AWD and has dual electric motors - one at the front and one at the rear.

Without the optioned AMG Dynamic Plus Package, the motors produce up to 460kW and 950Nm but with the package those outputs jump up to a staggering 505kW and 1000Nm!

That means the 3.7-second 0-100km/h sprint time also improves to 3.5-seconds. Suffice it to say, it's enough to blow your hair back and considering we have no roads in Australia you can really let this thing loose on, it's more than enough power for anyone.

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.

Non-AMG EQE models see decent driving ranges over the 500km mark, but the EQE53 has an official range of up to 485km which again positions it in the middle of its rivals. So, not bad, but a larger range would be welcome as the EQE53 is a comfortable road-tripper!

The EQE53 has a a claimed consumption figure range of 23.0 to 25.6kWh and a lithium-ion battery with a large 90.56kWh capacity.

After a week of open-roading, city-driving and not being shy in using its power, my average has been around 25.5kWh, which is solid for an electric performance SUV.

The EQE53 has a Type 2 CCS charging port which means you can hook it up to the faster DC chargers and it accepts up to 170kW on this type of system meaning it goes from 10-80 per cent in as little as 32 minutes. On an 11kW AC system, expect it to hit 100 per cent after 14.5 hours. 

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.

I really wanted the AMG EQE to be crazy-fun like its petrol-powered cousins but while it has the specs to support that wish, it never feels wild.

That's not necessarily a bad thing, just unexpected for an AMG model. The 53 is still one cool customer and its composure on the road is wonderful but it's a model that a grandparent could get into and not feel overwhelmed by. Power is smoothly delivered and when you need to take off, it responds eagerly .

Steering is firm and responsive but it’s the rear axle steering that makes the EQE53 feel nimble in the city or a tight car park despite its bulky size. It corners well, without much roll and you can tackle a winding road at speed with confidence.

The ride comfort is very good with minimal outside noises finding their way inside and the suspension is plush without feeling like you’re floating on top of the road.

The visibility is mostly good but the wide A-pillar is annoyingly in the way for my driving position and I have to duck my head around it to see clearly on roundabouts.

The 360-camera system is top notch but the camera angle turns when you move the steering wheel, which takes some time to get used to. Otherwise, the EQE53 is an easy one to park.

The EQE53 hasn’t been assessed by ANCAP yet but its siblings achieved a maximum five-star safety rating in 2023.

The top model enjoys a long list of safety features, including 10 airbags which is outstanding for a family SUV.

Other systems include blind-spot monitoring, an SOS call button, driver monitoring, safe exit warning, rear occupant alert, rear collision warning, forward collision warning, rear cross-traffic alert, lane departure alert, lane keeping aid, traffic sign recognition, an intelligent seatbelt warning, adaptive cruise control (with stop/go), park assist, a 360-degree view camera system as well as front and rear parking sensors.

There are two ISOFIX child seat mounts and three top tether anchor points across the second row but two seats will fit best.

None of the safety systems intrude on daily driving either, which is great.

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.

The EQE SUV is offered with a five-year/unlimited km warranty, which is not unusual for its grade level but it has a longer-than-usual battery warranty of up to 10-years or 250,000km.

You can pre-purchase a three-, four- or five-year servicing program. The three-year program costs a flat $2240, while the four-year program costs $3525 and the five-year option costs $4085.

All pricing is pretty competitive for the class but servicing intervals are odd at every 12-months or 25,000km as it's typical to see intervals on EVs at 24 months.
