Lexus IS VS Audi A8
- Good value
- Great after-sales
- Dodgy entertainment system
- Unmistakably Audi
- Amazing interior design
- Groundbreaking safety features
- Pricey options
- Most of its autonomous tech locked out for Aus
This generation of the Lexus IS has been with us for a while now, and it has a lot more to contend with than it did on its debut. The Infiniti Q50 has come and gone, but a new Audi A4 (soon to be refreshed) and a very impressive new BMW 3 Series made life difficult. And that's before everybody wakes up to Genesis, which could bloom into a real threat.
Lexus has carved itself a bit of a niche in this country, going after just about every luxury segment worth chasing (and one or two that possibly weren't...) but the IS has been getting on with the job of presenting itself to customers who have either tired of German luxury or just weren't interested in the first place.
The third-generation IS must soon be heading for replacement, so it's worth having another look to see how the Japanese challenger fares.
|Engine Type||2.0L turbo|
|Fuel Type||Premium Unleaded Petrol|
In a world where genuine wood trim and nappa leather comes in a Mazda6 for under $50,000, premium brands like Audi have been forced to come up with new hallmarks to underpin their status and asking prices.
The new, fourth-generation Audi A8 is no different, packing hardware capable of autonomous driving well ahead of what is currently allowed on any public roads, along with an array of safety, efficiency and convenience firsts for the brand that cement the model's position at the top of the four-ringed luxury tree.
The current S-Class may measure your vital signs and aim to improve your general well-being, but it won't give you a foot massage. If you tick the right options boxes, the new A8 will.
We were among the first to drive the new A8 at its Australian launch around Sydney last week.
|Engine Type||3.0L turbo|
It's difficult to place the Lexus against any of the Germans because it's a different sort of car. Its intent is probably closer to the Benz C-Class than the more overtly sporting BMW 3 Series or the all-rounder Audi A4. All three of those cars are way ahead for cabin, chassis and engine technology (depending on spec levels, of course).
None of them feel as solid or, ultimately, as tightly built as the Lexus. The IS has a very consistent idea of what it's meant to be and it goes all the way back to the LS400 - something identifiably similar but different enough to lure you to Japan.
The new A8 is a very accomplished machine, and can certainly be optioned up with enough toys to entertain and comfort whether you're riding in the front or back.
It's not possible to say if its better than the S-Class or 7 Series in isolation, but it has a unique design ambience that's unmistakably Audi. If you're a four-ring devotee, you won't be missing out.
Based on this test, the sweet spot of the range is the long-wheelbase 55 TFSI. At this end of the market, it's fair to say the extra $12,000 for the added length and $3000 for the smoothest and most powerful engine are worth it.
Regardless of the bigger wheels, we'd probably spring for the Premium plus package and the Executive package's rear seat with the Entertainment package for all the most impressive toys. This would mean a total list of almost $250k, but it's arguably how Audi intended the new model to be.

Would you consider the new A8 over an S-Class or 7 Series? Tell us what you think in the comments section below.
The first IS is still - remarkably - a common sight on our roads and couldn't be more different to the current generation. This car is low and sleek, with fast glass and big bold statements, like the huge spindle grille. That grille was a bit weak when this first generation arrived, but the mid-life facelift fixed that, but didn't touch the headlights, which still look a bit melted. Then there are the "big tick" daytime running lights, which don't really work with the headlights. It's all a bit odd.
Inside, things are very grey and sober. Obviously, it's astonishingly well-built, but there are just too many carefully labelled buttons and way too many switches you can spot in your neighbour's Toyota Corolla. They're not bad buttons, they just don't fit with the vibe of the rest of the car. Everything is clear and crisp, though, and the materials feel and look fantastic. It feels properly expensive.
At first glance the new A8's exterior styling may look a tad obvious, with unmistakably Audi design adding a bunch of straight lines to make things look more serious.
The reality is far more considered, being the first whole design to emerge under Audi Design boss Marc Lichte's stewardship. Previewed by the first Prologue concept in 2014, the result has an elegance that underlines its position as Audi's flagship and is less likely to be confused with an A6 than the S-Class can be with the E-Class.
If you're after the ultimate in design details and lighting performance, you can also opt for $13,200 laser headlights that can double the range of LED headlights to 600m ahead. This option also brings OLED tail-lights with jewel-like filaments less than 1.0mm thick.
Compared with the third-generation model it replaces, the size of the new A8 is 37mm longer, 13mm taller but 4.0mm narrower, riding on a 6.0mm longer (2998mm) wheelbase. The long wheelbase version is 130mm longer again in wheelbase and overall.
In A8 guise, it combines aluminium, steel, magnesium and CFRP to result in the biggest material variety used in an Audi to date. Kerb weight ranges from 1995kg for the short-wheelbase petrol model to 2020kg for the long-wheelbase version, with the diesel versions adding 55kg respectively.
A 15-spoke, 19-inch wheel design is standard for Australia, but the Premium plus package fitted to all the cars we tested brings a 10-spoke 20-inch design, while the options list includes another three choices of 20-inch wheels. You can also get 21-inch alloys with the optional Sport package.
As you'll see in the interior images, the A8 represents another significant step forward for Audi design, with horizontal themes and numerous traditional controls now hidden beneath touchpads.
Key among these is the deletion of the centre console controller for the multimedia system, which has been replaced by an 8.6-inch secondary touchscreen beneath the 10.1-inch main screen. Apple CarPlay and Android Auto smartphone interfaces are available via USB connection, and the A8 will act as a mobile Wi-Fi hotspot if you sign up for a data plan.
This split layout is less imposing than using one giant screen as in a Tesla, and both give haptic and acoustic feedback to commands to simplify use while driving. All versions also score the excellent 12.3-inch 'Virtual Cockpit' display ahead of the driver.
All A8s also now get a smartphone-like back seat remote controller, which enables control of temperature settings, seat adjustment, lighting, media functions and window blinds (when optioned) via its 5.7-inch OLED touchscreen.
Another surprise detail is that the interior door handles are now power assisted, which represents the lengths Audi has gone to in reducing control weights.
For some reason, the IS has always had a tight rear seat, despite its growth over the years. Handily, one of my neighbours has the iconic original IS200, and there isn't a big difference between the two cars, despite being separated by two decades.
This IS has such a flat windscreen that you have to be careful not to whack your head when you're getting into the front seats. The glass is super-fast and no doubt that pushes the cabin space towards the rear. The front seats are uncommonly comfortable and you also get heating and cooling, so you're covered all year round for posterior thermal comfort.
Front and rear passengers enjoy a pair of cupholders each and a bottle holder in each door.
The boot swallows a suspiciously identical-to-the-Euros 480 litres.
Choosing the biggest sedan in the line-up isn't just about outdoing your neighbours, it's also fair to expect enough room to stretch out and ponder your stock options.
Despite the new A8's minor 6.0mm wheelbase growth, the interior dimensions have grown 32mm in length, which has expanded legroom as well as headroom.
Fundamental practicality elements are covered as well, with a cupholder and bottle holder for each outboard passenger, an array of USB and 12-volt charge points and two ISOFIX child seat mounts for the back seat. There's also a Qi wireless phone charger within the centre console.
Boot space is a useful 505 litres, and while there's no split-fold for the back seat, there is the capacity to bring curtain rods home from Bunnings via the ski port. There is also a space saver spare wheel beneath the boot floor.
Price and features
At $59,340, the IS300 Luxury opens the range, stacking up well against the obvious luxury competition. That scores you a 10-speaker stereo, 17-inch alloys, dual-zone climate control, heated and cooled electric front seats, reversing camera, front and rear parking sensors, active cruise control, sat nav, auto LED headlights with auto high beam, headlight washers, keyless entry and start, partial leather trim, power everything, auto wipers, and a space-saver spare.
The standard complaints about the Lexus entertainment system still apply - it's hard to use, is devoid of Apple CarPlay and Android Auto and takes longer than it should to learn where everything is. The sound, however, is excellent from the 10 speakers, the screen is huge and (mostly) pretty and the sat nav works quickly and without fuss.
The fact that the new A8's entry price has dropped almost $6000 to $192,000 is likely to have less impact than a $19,990 Hyundai i30 special, but Audi's claim that it offers up to $36,000 more value than before may lower a few bifocals.
Introducing Audi's new naming scheme, which no longer makes reference to engine capacity in preparation for electrification, the diesel base model wears a 50 TDI badge, before moving $3000 north to the petrol 55 TSFI. Either models can be had in long-wheelbase form (signified by a capital L after A8) which will cost you an additional $15,000 respectively.
The $210,000 A8 L 55 TFSI at the top of the price list is more than $42,000 cheaper than the previous V8 diesel 4.2 TDI and a more than $120,000 less than the previous S8 Plus, but a new performance flagship is due to appear in the near future.
Value is rather subjective at this end of the price scale, but by comparison the entry RRP for the new A8 undercuts the base 7 Series by $34,900, the S-Class by $3900, but starts $1871 above the Lexus LS.
Both the A8's 50 and 55 engines come with the same trim levels, but when the standard kit is this lengthy it's more a matter of features not included in the A8, rather than those that are.
As you might expect, there's an array of options available. These accessories range from the aforementioned wheel choices and laser lighting to $3600 Alcantara headlining, $4500 all-wheel steering, a $5200 night vision system, or $12,100 3D Bang & Olufsen sound system with 23 speakers.
There are five options packages also, starting with the $6690 'Entertainment package' which brings a six-disc DVD/CD changer (on top of the standard DVD/CD player) and twin tablets for the rear seats which mount to the front seat headrests.
The nappa leather trim can be expanded to the upper and lower dash and glovebox, door trims, headrests, centre console, steering wheel airbag cover and the backs of the front seats with the 'Full leather package' for an extra $9950.
If you can't hold out for the sport edition S8, you can almost look the part with the $9950 'Sport package', which brings a more aggressive front and rear bumper, 21-inch wheels, all-wheel steering and expanded 'piano black' interior trim.
Audi Australia tells us all A8s ordered to date (along with both cars pictured here) have ticked the $11,000 'Premium plus package', which brings 20-inch rims, adaptive windscreen wipers with integrated jets, chrome exterior details, ambient lighting with variable colours, black control buttons, digital TV, electric rear sunblinds, the full leather package mentioned above, interior fragrancing with ionisation technology, rear tinted windows, softer rear headrests and ventilated massage front seats.
If you've already selected the rear seat entertainment system, you can also choose the $18,500 'Executive package' which brings individual reclining back seats and extended centre console - which also eliminates the centre rear seat - with folding tables, front and rear seat ventilation and massage function, heated armrests all round and a heated steering wheel. It's the Executive package that also brings the heated rear passenger-side footrest and the foot massage USP.
Engine & trans
Under the long bonnet is a 2.0-litre four-cylinder turbo petrol engine with a very reasonable 180kW and 350Nm, carrying the code number 8AR-FTS. An eight-speed automatic sends the power to the rear wheels and will propel the 1680kg machine to 100km/h in seven seconds flat.
You can tow 750kg with an unbraked trailer and 1500kg braked.
You might be surprised to learn there's no V8 in the new A8's arsenal - for now, the S8 could change that - but an even greater sign of the times is the return of a petrol version for the first time since 2013. Efficiency gains are the main reason for the petrol comeback, which is explained in detail under the fuel consumption heading below.
Both the 210kW/600Nm 50 TDI turbo-diesel and 250kW/500Nm 55 TFSI petrol specifications use 3.0-litre turbocharged V6s which may seem to be simply plucked from existing models, but they bring mild hybrid technology to the Audi line-up for the first time.
Unlike conventional hybrids that use an electric motor to provide horsepower to drive the vehicle, a mild hybrid (or MHEV) enables the combustion engine to be switched off when the vehicle is coasting or braking, or effectively as an extension of a start/stop system which conserves fuel when a car is stationary.
The A8's mild hybrid system is facilitated by the move to a 48 volt electrical system, with a supplementary 10Ah lithium-ion battery mounted in the boot to keep the electrical systems fed for up to 40 seconds with the engine switched off. Audi claims the system has the capacity to save up to 0.7L/100km.
An extra starter motor has been integrated with the alternator to restart the engine more smoothly via a belt, rather than the conventional cog and ring gear used by the dedicated starter motor for cold starts.
Both engine specs deliver their max torque rating from just above idle, with the 50 TDI at 1250rpm and the 55 TSFI at 1370. Claimed 0-100km/h acceleration performance figures are an impressive 5.9s and 5.6s respectively.
Like all recent longitudinal-engined Audis, the new A8 uses a version of ZF's much lauded eight-speed torque converter auto gearbox, and both engines send power to all four wheels via the 'quattro' all-wheel drive system.
The optional all-wheel steer system can twist the rear wheels by as much as five degrees, reducing the turning circle by around 1.0m at slow speeds. While at higher speeds, the rear wheels move parallel with the fronts by as much as two degrees to improve stability, particularly for rapid lane changes and evasive manoeuvres.
All new A8 variants carry a maximum braked towing capacity of 2300kg.
The sticker on the windscreen suggests you might get 7.5L/100km, drinking premium unleaded. Unfortunately, and despite my fervent efforts, the best I could manage was a far more sobering 12.7L/100km.
That's not a great result, and it's quite similar to the 200t I drove a couple of years ago. Even with stop-start.
Gone are the days where full-size luxury sedans got away with devil-may-care fuel consumption, and even though they still spin six cylinders and need to move around two tonnes, the 55 TFSI petrol versions manage an 8.2L/100km official combined figure. This is when using at least 95 RON Premium unleaded of course.
As you'd expect, the diesel fuel economy is even better with 5.9-6.0 official figures across wheelbases.
With a fuel tank capacity of 72 litres, this suggests a theoretical range between fills of 878km for the petrol models, and between 1200-1220km for the diesels. The A8's spec sheet lists the option of an 82-litre tank if they aren't quite far enough for you.
From the driver's seat you get that very appealing sense of solidity that you get in every Lexus, even the baby SUV UX. That's partly because when a car weighs this much, it helps soak up the bumps. Lexus has a particular ride quality, even in its sportier variants, that makes you feel safe and cosseted.
The steering's weight is light, but not so light you can't feel what the wheels are doing, yet it's not overly chatty.
But the main contributor to the feeling of solidity and safety is realising how unbelievably quiet and smooth the IS is. Even the turbo four is the most distant of whirrs (without sounding bad), smoothly dishing up the power and torque. I'll admit to more than mild surprise when I saw the 0-100km/h time of seven seconds - it just doesn't feel that quick, but the speed does indeed pick up.
The eight-speed automatic could be more decisive - I often found myself grabbing a lower gear because the transmission had been a bit tardy picking the right cog. It could also drop into third or fourth a little too firmly when in Sport mode. It wasn't bad, it just felt like it was making a last-second decision to pick the gear and then ramming it home a touch enthusiastically. In normal city driving, however, it's smoother than the butter through which a Barry White track is being played.
As a sporty sedan it does okay, too, but the suspension is really set up to keep everything calm and comfortable. The electronics cut in early and often on slippery surfaces and even Sport mode is pretty tame. And that's perfectly okay.
Our test started in the worst of Sydney morning traffic, which presented the chance to put the latest adaptive cruise assist (ACA) system through its paces on a very clogged Eastern Distributor.
I'm a huge fan of active cruise control systems that guide the vehicle from speed to a stop, but the A8's ability to start moving again is another step beyond. It helps you avoid being ‘that guy' who hasn't noticed the traffic moving, and would no doubt work wonders for traffic flow if all cars were so equipped. Given the chance, Audi says this system works all the way from 0-250km/h.
No matter what your reaction to the A8's exterior, the freshness of the interior design is like no other, and everything you touch feels first class.
The four-spoke steering wheel has a surprisingly large diameter and is shared with the upcoming A6, but uses thinner spokes than the norm to promote visibility of the virtual cockpit display as the wheel is twirled.
The haptic and acoustic screens make it as easy as we've experienced to handle a touchscreen while driving, but not quite as simple as the previous console controller.
Front and rear seats are softly padded for comfort rather than support, and unsurprisingly there's ample room in every direction for this 172cm tester, regardless of wheelbase.
All examples of the A8 we drove were optioned with the Premium plus package, which means one inch larger 20-inch alloys. Despite all A8s coming standard with adaptive air suspension, small bumps like cats eyes and expansion joints are more noticeable than you might expect. As is often the case, the standard 19-inch alloy wheels are likely to be the solution.
We drove both engines and wheelbase choices at the A8 launch event, and you need to be paying close attention to hear any extra noise from the diesel. It does make a muted groan under throttle, but likely worth the 300-plus kilometres of extra range if that's what you're after.
The diesel's smoothness is also no doubt aided by its use of active engine mounts. If you're after outright refinement and performance, the petrol is the one for you but neither feel in any way sluggish.
Heading through the bends of the Royal National Park and then back over the hills via Macquarie Pass at pace, there was no disguising the fact that the A8 is a big car, and it tends to float unless you select 'Dynamic' from the drive mode selector. Regardless of mode, it's more planted than any luxury SUV.
Making a bee-line back to Sydney via the Hume, the A8 simply wafted along at 110km/h in near silence. As you'd expect.
The IS lands with eight airbags, ABS, stability and traction controls, brake asssist, forward collision warning, forward AEB with pedestrian detection, lane-departure warning, lane-keep assist, active-safety bonnet and tyre-pressure monitoring.
There are also two ISOFIX points and three top-tether anchors.
The IS scored the maximum five ANCAP stars in December 2016.
The airbag count has been further bolstered by an industry-first centre airbag, which has been designed to prevent head clashes between front seat occupants. This also represents Audi thinking beyond any Euro NCAP or ANCAP criteria.
It also comes with Audi's exit warning system, which warns the driver of passing cars or cyclists but can now delay the door opening in case the driver doesn't see the warning light.
A front-mounted laser scanner replaces the usual radar system for active cruise control and front AEB, which doubles the range of a radar scanner to 80m and enables both functions to work at speeds up to 250km/h.
This laser scanner is also key to the A8's Level 3 autonomous preparation, but local laws limit its capability to active cruise control with lane assist.
Lexus offers a slightly unusual four-year/100,000km warranty, which I guess is a good way to separate yourself from the Euro competition, who are stubbornly sticking with three years. Added to the warranty is four years of roadside assist.
Also throwing a punch at the Euro manufacturers' generally lacklustre after-sales offering, Lexus offers to either come and fetch your car from you for servicing or will give you a loan car for the day. And you'll get your car back freshly washed and vacuumed, too.
All of this (and a reputation for bulletproof reliability) is intended to lure you away from the Germans.
Like all Audis, the new A8 is covered by a three year, unlimited kilometre warranty. This is short of the five year-plus periods becoming more common among mainstream brands, but equal to the terms offered by BMW and Mercedes-Benz. Lexus differs by offering a four year, 100,000km plan.
Service intervals and capped price servicing mirror the previous A8, with a 12 month/15,000km schedule, and maintenance costs for the first three services can be wrapped into a package for $1900.
We had no issues during our test, but any common faults, common problems or reliability issues are likely to appear on our A8 problems page.
