Audi A5 vs Lexus IS

What's the difference?

Predictably stylish, predictably competent, predictably comfortable. In fact, that predictability is among its only downsides. In short, the updated A5 might not move the needle all that much, but it didn't need much moving in the first place. 

Smooth, cosy, quiet, the IS looks and feels better than ever, but without a doubt this hybrid version is a car best suited to cruising the dense metropolis of Chiba at midnight more than it is carving up a bunch of S-bends in the Australian countryside on the weekend.

While that might still limit its appeal for fans of German sports luxury sedans and place it further from the original IS’s ambitions, it does offer an intriguing efficiency and luxury focused alternative, without the compromises brought by rivals with more sporting intent. In a way then, the IS 300h perhaps inadvertently best embodies what Lexus is as a brand.

It's gorgeous, the A5. There's simply no disputing it. It's elegant, sophisticated, and above all, restrained. There's no look-at-me chintz here, just clean lines, sharp creases and a shapely figure.

Like its A4 sibling, the A5 has been tickled at the front, with a new-look grille, along with a new headlight cluster with redesigned DRLs, and Matrix LED headlights. 

The four sharp bonnet creases that fan out from the grille lend the A5 a sense of speed, even when stationary, and we love the way the 19-inch alloys fill the wheel arches. It looks polished, premium and athletic. 

Inside, Audi's interior treatment is on-point, from the figure-hugging leather seats to the material choices that span the dash. The big news in the cabin is the inclusion of Audi's new 10.1-inch touchscreen perched above the dash, which isn't just easier to use (in my opinion, at least), but also removes the traditional controls from the centre console. 

It means Audi's already fuss-free cabin is even less cluttered, and it's definitely a change for the better. 

Look closely and quite a lot has changed. This is really a story of doing a facelift right. Lexus has kept all the great-looking bits of the car that launched in 2013, like its striking side profile and angular accents, while dumping most of its least popular elements like the spidery front light-clusters and busy front splitter, in favour of something more refined and conservative.

It even adds some new flair in the rear three-quarter, with dramatic LED light-clusters working their way into a trendy highlight strip across the boot lid.

These changes all add up for a much tougher, sportier, and nuanced design compared to the outgoing car. One that manages to make an eight-year old design look as contemporary as ever.

I even liked our test car in its plain black shade, although I'm less sure about those conservative-to-a-fault, almost Camry-esque alloy wheels.

On the inside, sadly not a whole lot has changed. The busy design looked dated when this generation of IS launched in 2013, and it still looks dated now.

The visual assault of buttons, toggles, displays, textures, and trims is a lot to take in, and makes the cabin feel smaller than it is.

It probably didn’t help the sensory overload of this car’s interior as I hopped out of the stripped-back interior in the Tesla Model 3 I had the week before.

My less-than-impressed brother, a student of design, described the IS’s interior best when he told me “It’s a bit maximalist, don’t you think?”

If nothing else, at least Lexus hasn’t blatantly imitated anyone else when it comes to its interior, but the brand remains firm on dorky design items like the laptop touchpad, redundant drive-select dial, and odd vacant panels under the climate unit which do it no favours.

A welcome upgrade for the 2021 model year is the new media screen, a highlight piece perched atop the dash. It’s bright, has excellent contrast, and doesn’t seem to fall victim to glare.

The Apple CarPlay support I used was seamless and sharp and made the most of the available real-estate in its widescreen layout.

I somehow didn’t mind that the instrument cluster in this base car is analog. It almost suits the IS’s character better than a digital set-up would. Also offered is a small information display between the dials which I used for monitoring the hybrid drive.

A final note on the IS’s design. The fit and finish is quality, inside and out. It leaves you with an impression that this is an immaculately built vehicle, one that should be a must for all luxury cars, and always a strong point for Lexus.

It very much depends on the model you've opted for, with the Coupe compromising backseat space for exterior style. 

The Sportback is easily the most practical of the trio, what with its four doors, comfortable backseat and dimensions that stretch 4757mm in length, 1843mm in width and 1386mm in height, and its 480 litres of boot space.

The Coupe, then, is a two-door design, stretching 4697mm x 1846mm x 1371mm, with 450 litres of luggage space at the rear. It's long, the Coupe, but most of that space is absorbed by the front half of the cabin, wth the backseat reserved for kids. 

Finally, the Cabriolet (which we're yet to test) stretches 4697mm x 1846mm x 1384mm, and will deliver the lowest luggage capacity of the lot, at 375 litres.

Elsewhere, though, the A5 range delivers two cupholders up front, with another two in the centre armrest that can deploy to divide the rear seat. Rear-seat riders also get air vents with their own temp controls, USB charge points (joining the two up front) and bottle holders in the doors. 

For parents, you'll find a pair of ISOFIX attachment points in the backseat, too. 

Well, the IS is a sedan, so it doesn’t quite have that high-riding appeal of an SUV, and for this update it has even leaned further into its low-slung proportions with a roofline that descends a further 15mm and a boot lid which is 31mm lower overall.

As with the previous car, the interior is quite closed-in thanks to that busy dash design and large centre console. Rather than feeling claustrophobic though, it is best described as cosy, with lots of plush finishes throughout the doors and centre stack befitting a luxury nameplate.

Adjustability is great for the front two occupants and there are two large bottle holders between the seats, a large but shallow console box under the armrest, bottle holders with adjoining bins in the doors, and a smallish glove box.

That’s about where storage ends though, with no extra trays or bins in front of the oddly placed shifter, just an awkwardly finished plastic panel where it feels like a little tray or storage cutaway should be.

The touchpad for operating the media screen joins an unnecessary drive-select cluster in eating up centre console space where there could be more storage.

The rear seat is quite limited on space despite being lavishly trimmed. I fit behind my own (182cm/6'0") driving position with little knee or headroom to spare.

Again, it’s cosy and very comfortable, but if you're taller or wider than me you may run into issues.

The centre rear seat is all but useless for adults, with the IS’s rear-drive architecture necessitating a huge transmission tunnel that almost comes as high as the seat base itself.

Storage is limited to pockets on the back of the front seats, small bins in the doors that double as handholds, and a drop-down armrest with two bottle holders.

There are no power outlets for rear passengers, but there are dual adjustable air vents.

Boot space is 450L which is a little small for the class. It’s impressive the hybrid only managed to lose 30 litres compared to petrol-only IS variants, though, so best to count your blessings.

The largest CarsGuide travel case easily fit in the wide but short available space.

To be precise the variant we’re looking at here is the IS 300h Luxury. It’s the base IS trim with the hybrid powertrain and it wears a before on-road costs (MSRP) of $64,500.

Base car or not, the new IS is very well specified. Now standard are 18-inch alloys (up from 17s), full LED headlight clusters, eight-way power adjustable front seats, dual-zone climate control, 10-speaker audio system, and importantly a brilliant new 10.3-inch multimedia screen with widescreen Apple CarPlay, Android Auto, built-in navigation, and DAB+ digital radio support.

Keyless entry and push-start ignition also continue to be offered, as well as a leather-look interior trim which in our car was in a rather contrasting 'Ochre' colour option.

Our IS 300h was also fitted with the creatively named ‘Enhancement Pack 1’ which adds an openable moonroof for $2000. The significantly more expensive ‘Enhancement Pack 2’ ($5500) adds the moonroof alongside 19-inch alloys, upgraded LED headlights, interior ornamentation, scuff plates, a panoramic reversing camera, 17-speaker premium audio, ‘leather-accented’ interior trim, ventilated front seats, and an electric rear sunshade.

These packs are seemingly largely unnecessary but are also very cheap for a brand at the premium end of the market.

Lexus has made pretty much all of its high-end active safety equipment standard on this base ‘Luxury’ for 2021, alongside some previously unavailable tech which we’ll take a look at in the safety section of this review.

At this price the Lexus IS 300h goes into battle against the Mercedes-Benz C 200 ($66,900), BMW 320i ($70,900), Audi A4 35 TFSI ($55,900), and the ever-looming threat of Hyundai’s Genesis, which offers its similarly-sized G70 in base form at $59,300.

Some of these base-spec rivals are cheaper, some are more expensive, but did you notice none of them are hybrids?

Access to Toyota’s affordable and popular hybrid drive is a real point of difference for the Lexus brand, and we expect it’s a key drawcard for the loyal customer base. More on that later.

Two choices here, the slightly tongue-twisting 40 TFSI and  and 45 TFSI quattro, both of which make use of a 2.0-litre turbo engine tuned for different outputs. 

The 40 will serve up 140kW and 320Nm, and pairs with a seven-speed S tronic automatic that shuffles that power to the front wheels. Audi reckons you'll see 100km/h in as little as 7.3 seconds.

The 45, on the other hand, will give you 183kW and 370Nm, pairing with the same auto gearbox, but this time sending power to all four wheels thanks to the quattro system. The 100km/h sprint drops to 5.8 seconds at its fastest.

The IS 300h does stand out from the luxury sedan crowd by offering a hybrid drivetrain at a reasonable price. Some rivals offer plug-in options further up the price scale cementing them as a niche option, but the beauty of this Lexus is its very mild $3000 price jump over the base petrol car.

The base car’s 2.0-litre turbo is dumped in favour of a 2.5-litre non-turbo Atkinson-cycle four-cylinder hybrid set-up similar to the one proving popular in the Toyota Camry and RAV4.

The petrol engine produces 133kW/221Nm on its own, and the electric motor produces 105kW/300Nm. Toyota says the “combined system output” of this is 164kW.

Either way, that's less than the base 2.0 turbo. The 300h also swaps out an eight-speed torque converter automatic in favour of a continuously variable transmission. Rare in a rear-wheel drive car.

Audi reckons the 40 TFSI engine will return 6.5L/100km on the combined cycle, and emit 148g/km of C02. The bigger engine increases fuel use to 7.1L/100km, but lowers the C02 output to 163g/km. Both those fuel numbers are taken from the Sportback.

Both engines also get a new 12V mild-hybrid system said to drop fuel use by up to 0.3L/100km.

Fun tank capacity is either 54 litres or 58 litres, depending on the model.

As you might hope this hybrid IS has an astoundingly low official/combined fuel consumption rating of 5.1L/100km.

I was pleased to find that after a week of mainly urban driving conditions, our IS was returning a figure of 6.9L/100km. Not bad at all, especially for a class where fuel consumption can get a little out of hand with turbocharged engines or V6s.

Of course, using the hybrid system to your advantage over the long term will get this number much lower, as I discovered on my long-term test of the Toyota Corolla hybrid which essentially uses a smaller version of the same system.

Certainly, if fuel consumption is a high concern, you’re better off with this car than the top-spec V6 (IS 350) which will easily see consumption enter double digits.

Lexus recommends a minimum RON rating of 95 for the IS 300h, and the fuel tank is 66 litres regardless of variant, giving the hybrid an impressive theoretical range of around 1000km.

You'd describe the A5's drive experience as evolved, rather than revolutionary, but to be honest, in a vehicle this competent, that's no small thing. 

The hybrid tech is unnoticeable, and so the A5 delivers an on-the-road feel that isn't far away at all from the car it replaces. None are truly fire-breathing, but it feels comfortable and sophisticated, the outside world largely banished from the interior (though the firm-ish ride can send road imperfections into the cabin).

Audi has done a stellar job of making the A5 feel connected to the road below it, and the world around it, without dialling down the comfort factor. The steering, light in its normal setting but firming up as you cycle through the drive modes, is direct, but not twitchy, the ride is firm, but not uncomfortable, the engine (at least, the 45 TFSI we drove on launch) is capable without being ridiculous. 

The end result is a predictably competent drive experience, with the A5 delivering in the areas it should, largely before you even notice. 

The only downside to all of that, though, is that the experience is so predictable, that there are few surprises, positive or negative, thrown in. It can leave you feeling slightly disconnected from the experience, rather than truly engaged.

Now, a disclaimer, we spent limited time in the A5 on launch, so we'll wait until we get it in the CarsGuide garage before making a final verdict. But I'd be surprised if we liked it any less over a longer period.

There is no doubt the IS 300h is capable. You can feel it through the car’s solid rear-drive underpinnings, silky smooth steering, and reactive chassis.

What this car doesn’t offer is excitement in quite the same sense as many of its rivals. That’s down to this hybrid’s drivetrain. It just doesn’t have that powerful follow-through in the same way turbocharged BMWs or Audis or Mercedes do.

If it’s that 'sports luxury' experience you’re seeking better off looking to the base 2.0-litre turbo or the V6 and their eight-speed automatics.

The 300h does offer something a bit different. The gentle refined efficiency of Toyota’s signature hybrid system in a luxury rear-drive package that’s smaller than this car’s ES bigger brother.

While it may feel capable thanks to the lighter suspension components and altered track that the brand has committed to for this update, the hybrid drive matches this car’s softer character brought about by its gentle suspension tune and light steering.

This is an easy car to drive around a city, it filters out bumps nicely, while offering near silence in the cabin and breezy steering for every day scenarios like manoeuvring in tight parking lots.

The CVT auto and instantaneous torque available from the electric motor make it best at traffic speeds, being both reactive and predictable, with silent acceleration when inching forward at the lights or cruising along at 50km/h.

As you might expect though, the wheezy Atkinson cycle engine and CVT conspire for a noisy and less than engaging experience under heavy acceleration.

It’s not as though you’re rewarded with particular vigour either, with this combination being a bit sluggish when a lot is asked of it.

It loses its reactivity and refinement at higher speeds or in the corners on country roads as the transmission elastically tries to keep up with the demands of the driver.

Still, few luxury sedans are quite as purpose-built for the toils of a city, and if you want to get drawn into this car’s hybrid drive antics, it’s easy to make a game out of saving fuel by trying to rely on its low-speed electric motor capability.

Really then, it leans into its urban luxury appeal. A luxury sedan for the streets of Tokyo. An ideal car in this class for the urban environment.

If you don’t care for the thrill of a turbocharger or frequently seek to explore the twists of your nearest B-road, you could do worse than the comfort and ambiance the 300h offers.

A full active safety suite is now standard across the IS range, including freeway-speed auto emergency braking with pedestrian detection (works during the day and at night) and cyclist detection (works during the day only), and a new intersection braking feature, lane keep assist with lane departure warning, blind spot monitoring, rear cross traffic alert with reverse auto braking, traffic sign recognition, adaptive cruise control, and auto high-beam assist.

There is also an auto SOS function, as recently added to the Toyota Yaris Cross, which automatically triggers if an airbag is deployed. On the topic of airbags, every IS has a thorough suite of 10 (dual front, dual side, quad head, dual front knee).

This all adds up with the standard array of stability, brake, and traction controls for a maximum five-star ANCAP safety rating, although the IS was last assessed way back in 2016.

The IS is built in Japan.

All Audi's are covered by a three-year, unlimited-kilometre warranty, with servicing required every 12 months or 15,000km.

You can pre-pay your service costs for three or five years, which will set you back $1800 for three years or $2820 for five years.

Lexus gets slightly ahead of the luxury pack with an extra year of warranty. While BMW and Audi still sit on three, Lexus offers four, but it is limited to 100,000km and is still outdone by Mercedes-Benz and Korean newcomer, Genesis, offering five-year/unlimited kilometre promises.

The IS has capped price servicing fixed at $495 for the first three years of ownership with roadside assist, and the brand will even pick up and drop off your car, or offer a free loan car during every 12 month or 15,000km service.

It’s worth noting that German rivals offer pre-paid service packages out to five years, and Genesis is trying to make a splash with free servicing.

Lexus does offer a luxury ownership program dubbed ‘Encore’ which includes invites to experiences and certain partnerships with restaurants and the like to keep potential owners enticed.
