Lexus IS vs Audi A4

What's the difference?

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.

The Audi A4 allroad 40 TDI quattro S Tronic is a nice-looking wagon that’s fun to drive.

It’s packed with tech, adequately functional for daily life and it’s also capable enough off-road as long as the driving surface is nothing more challenging than well-maintained gravel or dirt tracks in dry weather, and you’re not planning a rough-and-tumble expedition into remote bushland.

As I mentioned earlier, the great thing about adventures is that you can scale them to suit you and your vehicle and the allroad offers a nice stepping-stone for people who’d like to experience the outdoorsy lifestyle, before perhaps diving deeper into it.

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.

The allroad’s overall look is part of a range-wide refresh and it certainly fits in with the line-up’s updated aesthetic.

Because I’m a bloke who spends the bulk of my time in 4WDs – traditionally bulkier vehicles rather than slim city-friendly wagons – I’m not totally enamoured of the Audi’s style, especially in terms of trip-packing practicality. However, I can certainly appreciate the appeal of its quite low, sleek and streamlined appearance, which its tweaked chunkier grille adds some gravitas to. It’s just not my cup o’ tea.

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.

I’ll answer that question as a politician would – without actually answering the question.

The allroad’s interior looks good and certainly feels open and spacious, although the driver’s seat tends to feel a bit more snug as the dash is angled towards that position.

The new 10.1-inch touchscreen, home for most upfront functions, dominates the dash, in a good way.

The front seats are electrically adjustable with lumbar and driver memory.

There are plenty of places in which to put your everyday bits and pieces (including a decent storage bin/arm-rest), as well as charging points, including two USB ports, for your devices.

Need somewhere to put a cold beverage, mate? There are two cup-holders between driver and front-seat passenger, two in the fold-down centre arm-rest for the back-seat passengers, and bottle holders in all doors.

Back-seat passengers also get air vents, climate control, mesh seat-back pockets and grab handles. 

There is a 495-litre cargo space when the rear seats are in use, but that increases to 1495 litres when those seats – 40:20:40 split folding – are stowed away in the floor.

The Audi A4 allroad 40 TDI quattro S Tronic has a MSRP of $69,900 (plus on-road costs).

It has a 2.0-litre four-cylinder turbo-diesel engine unit (140kW/400Nm), a seven-speed S tronic automatic transmission, and Audi’s quattro all-wheel drive system. 

In standard guise this allroad’s features list includes a new 10.1-inch touchscreen (with Apple CarPlay and Android Auto), DAB+ digital radio, an Audi 10-speaker stereo, wireless charging for Qi-enabled smartphones, Audi’s Virtual Cockpit (a 12.3-inch digital display), smart key with push-button start, leather trim, three-zone climate control, as well as LED headlights, 18-inch alloy wheels, illuminated door sills, and overall tweaked exterior and interior styling.

It also has AEB with pedestrian detect, lane change warning, rear cross-traffic alert, front and rear parking sensors and a reversing camera.

But our test vehicle has a few different features and a fair few extras. Our allroad has a ‘price as tested’ of $75,681 (plus on-road costs), because it has Assistance plus package ($2900), which includes a raft of driver-assist tech, such as adaptive cruise control, active lane assist, collision avoidance assist, high beam assist, head up display, park assist (helps to steer the vehicle into a parallel or perpendicular parking space), as well as a 360-degree-view cameras 

It also has 19-inch Audi sport alloy wheels in 10-Y-spoke design ($1350), instead of the standard 18-inch alloy wheels in 5-V-spoke design, and metallic paint (Mahattan grey, $1531).

Note: when we were conducting this test, Audi announced that, among other things, it would release a new-gen A4 allroad quattro 40 TDI in early 2021 that would have an extra 10kW more than our test vehicle, so it’ll be a 150kW/450Nm machine.

For those of you into hot laps, the current-generation achieves 0-100km/h times of 7.9 seconds; the new A4 allroad quattro 40 TDI is claimed to achieve that mark in 7.3 seconds.

Pricing for the upcoming 150kW A4 allroad quattro 40 TDI as standard was set to be $70,700. 

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.

The Audi A4 all road 40 TDI quattro S Tronic has a 2.0-litre, four-cylinder turbo-diesel engine, producing 140kw at 3800-4200rpm and 400Nm at 1750-3000rpm.

It has a seven-speed S tronic automatic transmission and all wheel drive.

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.

It has claimed fuel consumption of 5.2L/100km (combined), but we recorded actual fuel consumption on test of 8.4L/100km – driving in soft sand likely negatively impacted that figure.

It has a 61-litre fuel tank.

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.

For a bloke who spends a lot of time in big, tall and bulky 4WDs, I felt like I was driving a go-kart. It’s that low, but it’s also that much fun – and it’s a very different driving experience to what I’m used to.

The allroad is 4762mm long, 1847mm wide and 1430mm high, and has a listed kerb weight of 1720kg. So relative to the 4WDs I usually steer around, this is light and low slung. It’s more car than SUV, that’s for sure.

Acceleration is rather punchy (the engine and auto are a decent match-up), steering is light but precise, and you can cycle through drive modes (efficiency, comfort, auto etc) to set up vehicle characteristics to suit your driving style and conditions.

The quattro all-wheel drive system helps to keep the allroad planted and composed at all times. 

Ride is on the sharpish side of firm and you do tend to feel every irregularity in the road surface – it is long and low and on low-profile rubber afterall.

The virtual cockpit plus – a 12.3-inch high-resolution colour display – offers a comprehensive read on all things to do with the allroad.

Throw around your superlative of choice – “sporty” and “dynamic” fit this allroad well – but I’m loathe to gush about its on-road performance much more than that because I reckon if any motoring journos are reading this – many of whom spend the lion’s share of their time swanning about in sports cars – they would have already choke-spat out their dirty chai with surprise by now.

The Audi A4 all road 40 TDI quattro S Tronic has the maximum five-star ANCAP safety rating.

It has eight airbags (dual front, front side, side bags front and rear, and curtains front and rear), as well as AEB with pedestrian detection, lane change warning, rear cross-traffic alert, a reversing camera, and front and rear parking sensors.

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.

This Audi has a three-year/unlimited km warranty. Service intervals are recommended every 12 months or 15,000 km, whichever comes first.
