Lamborghini Aventador vs Audi S5

What's the difference?

The Aventador isn't the best car you can buy for the money and truth be told, it isn't the best Lamborghini, which is a bit tough when you remember the only other car they make at the moment is the V10 Huracan. But it's all about the theatre as much as being a very capable supercar. 

I'm not a Lamborghini fanboy, but I completely get the Aventador. It's a because-we-can car, just like the Murcielago, Diablo and Countach before it. But unlike those cars, it's thoroughly modern and with the upgrades introduced to the S, it's faster, harder and enormously entertaining. 

As the last of a dying breed it delivers on everything a Lamborghini should - amazing looks, nutty price tag and an engine that excites not just driver and passenger but anyone with a heartbeat. It's by far the most charismatic car you can buy, no matter how many zeroes are on the cheque.

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.

Asking if there's anything interesting about a Lamborghini design is kind of like asking if the sun is warm.

While there are some geese out there in the corners of the internet who think Audi has ruined Lamborghini styling, there is absolutely nothing shy about the Aventador. It's an incredible looking machine and, if I may say so, shouldn't be had in black because you miss a lot of the madder details.

This car is all about the experience.

It might look close to the deck in the photos, but however low you think it is, it's lower. The roofline barely makes it to the bottom of a Mazda CX-5's windows - you need your wits about you in this car because people just don't see you.

It is absolutely spectacular - people stop and point, one chap sprinted an easy 200 metres to take a photo of it in the Sydney CBD. Hello, if you're reading.

Inside is pretty tight indeed. It's amazing to think that a car 4.8 metres long (a Hyundai Santa Fe is 4.7 metres) struggles to contain two people over six feet tall. My six foot two photographer's head left an impression in the headlining. It's a tiny cabin. It's not a bad one though, it even has a cupholder on the rear bulkhead behind the seats.

The centre console is covered in Audi-based switchgear and is all the better for it, even if it is starting to look a bit old (those bits are from a pre-facelift B8 A4). The alloy gearshift paddles are fixed to the column and are brilliant to look at and touch, while the digital dashboard - which changes with the driving mode - is fantastic even if the reversing camera is awful.

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.

Yes, well. There's not a lot of space because a V12 is not just big all on its own, all the ancillaries to support it rob a lot of the remaining space. Having said that, there's room in the front for soft bags with a 180-litre front boot, space for two people inside, a cupholder and a glove box.

And the doors open up into the sky rather than out like a normal car's. Who cares if it's impractical, it's hardly something that's going to stop someone buying one.

…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 Aventador S is powered by Automobili Lamborghini's 6.5-litre V12. You know it's a V12 because there's a plate on top of the engine (which you can see through the optional glass cover) that says so, and handily, tells you the cylinder firing order. That's a neat touch.

Buried deep in the middle of the car, this monster engine develops an astonishing 544kW (30kW up on the standard Aventador) and 690Nm. Its dry sump means the engine sits lower in the car. The gearbox is slung across the back between the rear wheels - the rear pushrod suspension actually sits on top of and across the gearbox - and is apparently brand new.

The transmission is known as an ISR (Independent Shift Rod) and has seven forward speeds and still just the one clutch. Power goes through all four wheels to the road, but it's clear the rears get the lion's share.

The 0-100km/h time is the same as the standard car, which kind of tells you that 2.9 seconds is about as quick as you can go on road tyres when you don't have four electric motors with torque from zero rpm.

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.

Hilariously, the official figure is 16.9L/100km. I doubled it without trying. Simple as that. If you're buying this car thinking it will be easy on the juice, you're insane.

Cheeringly, Lambo has at least tried, the V12 going silent when you sit at the lights, the best thing being the way it bursts back into life when you lift off the brake.

If you have the time available, it takes 90 litres of premium unleaded to fill the tank.

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.

In Strada or Street mode, awful. Everything is slow and doughy, particularly the gearshift which goes looking for a gear like dog looking for a stick you didn't throw, but instead hid behind your back. The low-speed ride is nothing less than terrible, fidgeting over every single lump and bump and is only slightly more appealing than being dragged along behind.

The gearbox is really the worst bit about it. Automotive history is littered with cars that laboured along with a single clutch semi-auto: Alfa Romeo 156, BMW's E60 M5 and today the Citroen Cactus is stuck with just such a dud transmission.

Like that old M5, however, there's a trick to making the gearbox work for you - show absolutely no mercy.

Switch the selector up to Sport, get off the highway or major arterial road and head for the hills. Or better still, a clear race track. Then the Aventador goes from a pain in the rear to a glorious, roaring, completely unhinged and unhinging battle cruiser. This car is all about the experience, from the second you lay eyes on it to the moment you put it to bed.

This isn't an everyday supercar and it's absurd to think Lamborghini thinks it is.

First up, there's the obvious entry point with those wacky doors. While it's tricky to get in, if you're under six feet and reasonably mobile, stick your backside in, keep your head down and you're in. If you've been clever, you've specified the glass engine cover so you can see out the back but the huge wing mirrors are surprisingly effective.

Has someone thoughtlessly parked the car in a tight spot? No trouble, the four wheel steer makes the car absurdly manoeuvrable given its extravagant length and width.

As we've already established, it's not much fun at low speeds, waiting until about 70km/h before things start to make a bit more sense. This isn't an everyday supercar and it's absurd to think Lamborghini thinks it is. It just isn't.

The old Aventador was not the most capable of machines but made up for it with its overall belligerence. The new S takes that aggro and dials it up. When you move the drive mode to Sport you are basically unleashing hell. You can pretend to be super-masculine and switch to Corsa (race) mode, but it's all about getting the car straight and getting you around the track in the most efficient way possible. Sport is where it's at if you want to have fun.

The Aventador is about being seen, but not before you've been heard - from two postcodes away. It really is utterly glorious when you have a stretch of road to yourself. The V12 revs furiously to its 8400rpm redline and the wallop of the upshift is accompanied with a fantastic bark and a burst of blue flame. And these aren't the best bits.

Approach a corner, stomp on the colossal carbon ceramic brakes and the exhaust erupts in a combination of bangs and pops and growls that puts a smile on even the most hardened car-hater's face. The fact it steers into corners with just a demure roll of the wrist, aided and abetted by that funky four-wheel steering system. It's just brilliant, addictive and truth be told, it gets under your skin.

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.

In an unexpected twist, you'll get a three-year/100,000km warranty and the option to increase to four years ($11,600!) or five years ($22,200!)(!). Having recovered from typing that, given the cost of something going wrong, that's probably money well-spent.

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.
