Audi A5 vs Lexus IS200T

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 Lexus range comes with a four year/100,000km warranty with roadside assist for the duration. Servicing is every 15,000km or twelve months, whichever comes first.

Sadly, there's no fixed or capped-price servicing regime, not even a pre-pay option like the stingy Germans. Lexus will only commit to indicative pricing, although the first service at 15,000km is priced keenly - it's free.

When you buy a Lexus, they don't like to let go of you. My father-in-law's original IS 200 is still fetched by the dealership - should he so desire - for its annual service. If he chooses to darken the dealership door himself, he'll drive out in a loan car. Nobody has ever stalked him at the dealership demanding he consider a new one.

The IS200t seems the pick of the IS bunch, despite pricing on par with a couple of the IS350s. It's a worthy alternative to the usual suspects, with its own look, feel and approach to luxury motoring. In fact, it's far more a luxury car than sports sedan, but manages to do both well. In the end, a BMW will edge it for handling and overall chassis grace, the Merc has that badge and the Audi is all-wheel drive and bang-up-to-date.

But none of them can touch the Lexus for after-sales service nor are any of them quite as well put together as the Japanese-built IS. It may not be as fast or as fun, but it's very, very good.

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 current IS is by far the most distinctive of the three generations. With a couple of exceptions, it is a terrific looking car. It looks long and low slung, like the best sporting sedans, with an almost Maserati-like approach to its proportions. The loud and proud Lexus spindle grille - the object of such derision when it first arrived - looks utterly fantastic and draws attention away from the odd, squished headlights.

it is one of most comfortable cars you can buy, for both front and (short) rear seat passengers.

Inside is less impressive, with a weird stacked dash and integrated screen. The materials are top notch, however and while the designers have tried to do something interesting with the dash design, there are better ideas out there they might want to consider next time around.

…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 IS's cabin is probably the weakest point of the car, with limited storage for your bits and bobs. Front and rear seat passengers do get cupholders for a total of four, but the rear doors don't have bottle holders, limiting you to the two upfront.

On hot days like Sydney's 2017 summer, those cooled seats are heaven-sent.

The centre console bin is small and is the only place for your phone apart from the cupholders, which isn't an ideal spot, let's face it. The boot is a German-matching 480 litres and you can split fold the seats for more room.

Having said that, it is one of most comfortable cars you can buy, for both front and (short) rear seat passengers. The front seats are especially good and on hot days like Sydney's 2017 summer, those cooled seats are heaven-sent.

The IS range kicks off with the 200t Luxury at $59,340, closely followed by the hybrid 300h, the V6-powered 350 ($65,390) and then the $73,540 200t F Sport. Pricing then heads up into the mid-$80,000s for the IS350 Sports Luxury.

The 200t F Sport's almost $74,000 price tag fetches you a car with 18-inch alloys, dual-zone climate control, reversing camera, front and rear parking sensors, a hefty safety package, electronic dampers, auto LED headlights, auto wipers, electric heated and cooled front seats, digital instruments, sat nav, keyless entry and start, leather (some real, some not) interior, variable ratio steering rack and power everything.

The 10-speaker stereo is Mark Levinson branded and is controlled by Lexus' own connectivity and sat nav suite. The sound is fantastic, the control system less so. Commands come from a few shortcut buttons (good) and weird mouse-type arrangement on the centre console that is largely infuriating. The less said about the on-screen graphics, the better - they're low-res and on occasions, amateurish. You can connect via USB or Bluetooth but the app integration is limited. You also get an at-first unfathomable DAB+ radio.

Once on boost, the engine is smooth with a lovely flat torque curve.

Options are limited to $1500 for premium paint, which makes up eight out of ten colours.

Out of interest, $74,000 gets you a reasonably well equipped BMW 330i M Sport or Luxury Line and a few hundred dollars more will get you into a hybrid 330e M Sport. Audi will cheerfully sell you a loaded-up A4 quattro 2.0 TFSI and Mercedes might be tempted to sell you a C350e. Infiniti will probably throw themselves at you with a V6 twin-turbo Q50 Red Sport rocketship, or at the very least a V6 Hybrid Premium.

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 200t denotes a 2.0-litre turbocharged four-cylinder under that long bonnet, delivering 180kW and 350Nm to the rear wheels via an eight-speed automatic transmission. This translates to seven seconds dead to 100km/h for the 1680kg sedan, which isn't hanging around.

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.

Try as we might - and we did - we couldn't get at all close to the claimed combined fuel figure of 7.5L/100km. We didn't even hit the standard plus 30%, but we did get 12.2L/100km. That's a fairly solid miss.

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.

After having the good fortune to step out of the IS350 and into the 200t, it was immediately apparent that the 200 is the better car. For a start, it feels so much more nimble. Sure, it doesn't have the seamless urge of that silky V6, but the 2.0 turbo does a fine impression of a bigger engine. Once on boost, the engine is smooth with a lovely flat torque curve. If you're off boost, though, you're in a bit of trouble - the eight-speed is reluctant to downshift and needed prodding from the steering wheel mounted paddles on occasion.

As with just about every Lexus, the ride is impeccable and refinement virtually unmatched in the class.

From a driving point of view, the fundamentals are better - less weight over the front wheels meaning the steering feels better, it turns in better and it moves more fluidly, which is impressive because the 350 isn't a slouch. Even the dashboard is better. The 350 has a traditional two clock arrangement where the 200t has a single dial in the middle that is digitally remastered. Press a button and it slides to the side to provide extra info on your choice of the available data. It leaves a fair amount of black space but it's easier to read and doesn't suffer as badly from reflections.

As with just about every Lexus, the ride is impeccable and refinement virtually unmatched in the class. There's something about the way a Lexus knocks the edge of all but the biggest bumps, sails over speed bumps and handles imperfections that is hard to beat and hard to find unless you're spending really big bucks. The adaptive damping never feels like it's doing anything which is exactly the point - even when switching to Sport+, there's an ease to the ride without it feeling loose.

You'll barely know the engine is there, and the way the transmission slurs around the gears means non-stop serenity.

Standard safety kit includes eight airbags (including knee bags for front seat occupants), ABS, stability and traction controls, blind spot sensor, lane departure warning, rear cross traffic alert, brake assist and driver attention detection.

The IS scored the maximum available five ANCAP stars when it was re-tested in October 2016.

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 Lexus range comes with a four year/100,000km warranty with roadside assist for the duration. Servicing is every 15,000km or twelve months, whichever comes first.

Sadly, there's no fixed or capped-price servicing regime, not even a pre-pay option like the stingy Germans. Lexus will only commit to indicative pricing, although the first service at 15,000km is priced keenly - it's free.
