What's the difference?
Audi’s flagship is the A8, a long, luxurious sedan where being driven is often as important as doing the driving.
To put this ultra-premium machine in context, it competes with other German heavyweights like BMW’s 7 Series and, of course, the Mercedes-Benz S-Class as well as Porsche’s Panamera. Not to mention the Lexus LS or Maserati’s Quattroporte.
What’s life like at the top of the Audi pyramid? Stay with us to find out.
The e-tron S was inevitable.
The marriage of the latest automotive trends – sporty electrified SUVs with specific performance bits, the e-tron S is as much rooted in Audi’s future as it is in the present.
Having been one of the earliest fully electric German cars in the space, and now with a few years of age on it. Can the e-tron S shine as one of the best? Read on to find out.
The Audi A8 swims in a luxury car shark tank where those paying the big dollars expect top-shelf everything. It delivers a serene driving experience whether you’re in the front or the back, in a superbly engineered and executed luxury sedan package. Not perfect, but very, very impressive.
The e-tron S looks mean, feels premium, and blends serious power with surprising grace under pressure. I still can’t shake the feeling I had with the standard e-tron, though, that this car is an Audi sports SUV first and an electric car second, and its weight holds it back from being as fun to drive as I think some rivals are.
If you love Audi and you want to go electric without stepping into something too unfamiliar it’s a great option. If you want an electric car which takes full advantage of what the next generation of technology can offer, keep an eye out, there’s plenty of fresh metal on the way.
The A8 is close to 5.2 metres long, yet instantly recognisable as an Audi thanks mainly to its evenly weighted proportions, gently curved roofline and overall high-waisted design. Worth noting its drag coefficient (Cd) is an impressively slippery 0.25.
The characteristic look is accentuated by the brand’s signature, six-sided grille, in this instance highlighted by a matrix of high-relief chrome accents. And typically angular LED Matrix headlights sit either side.
Check out our video review for the carefully orchestrated animation they run through when the car is unlocked.
The car looks equally svelte and contemporary from the rear, with just the right amount of chrome lifting the tone and multi-spoke 20-inch rims filling the wheel arches nicely.
As you’d expect, the top-shelf look and feel continues inside with the seats trimmed in aniline leather, perforated on the front and outer rear positions, with genuine hide also covering the centre console, door rails and armrests, steering wheel and upper dashboard.
Fine grain ash wood inserts sit alongside brushed metal elements and a meticulous attention to detail is obvious… everywhere.
For example, the interior door handle design has been thoroughly thought through, requiring a simple underhand tap to open the door, rather than the more conventional, and ergonomically convoluted, ‘over the top’ movement.
Three sleek screens dial up the tech - a 10.1-inch multimedia interface at the top of the centre stack, an 8.6-inch display below it for heating and ventilation, and a 12.3-inch version of Audi’s ‘Virtual Cockpit’ in the instrument binnacle.
And the spacious rear is the epitome of cool, calm Teutonic form and function. You feel relaxed the moment you get in, and isn’t that the primary aim of a car like this?
The e-tron S looks properly mean, with its adjustable ride-height suspension and enormous wheels combining nicely with the extra subtle sporty highlights to make for a squat SUV which clearly means business.
The width is especially evident with those accentuated wheelarches and the lines set by the lower wing to draw your eyes out to its edges. In profile it's easy to see its long wheelbase and tapered rear roofline, giving even the SUV a slinkier frame than you may be used to when looking at the comparatively boxy Q5.
The thing that strikes me about Audi’s e-tron range, though, is how little a departure it is. It ambiguously slots somewhere above the Q5 and below the Q7, but sticks very closely to the German brand’s styling script.
Sure, it looks a bit lower to the ground, and a bit meaner than you might expect for an EV, but it’s not as much of a departure as Jaguar’s I-Pace or BMW’s iX.
I suppose the biggest advantage here is nobody is going to say the e-tron’s overall visage is controversial, and certainly, it will appeal to existing fans of Audi’s design.
Inside it follows much the same theme, with all the key touchpoints and styling elements nearly identical to other Audis in the range, if not very similar.
It feels like a sensible, refined place in the cabin, with the only whacky pieces being the extra touchscreen for the climate unit and the strange thumb-operated shifter mounted on a floating piece which looks and feels like it could be the throttle control for a jet engine.
The dash is a bit more integrated and modern than in the conservative Q5 or Q7, with the air vents leading to the digital instrument cluster as part of an aesthetic three-terrace design which runs across the entire dash and into the doors.
The screens which appear in place of wing mirrors take a bit of getting used to. Aside from those notable departures, the interior continues the theme of sticking closely to the Audi formula, providing a more modern space which will still be familiar to existing fans of the brand.
Space is luxury, be it a large house, a first class seat or a spacious car, and at nearly 5.2 metres long with a close to 3.0m wheelbase the Audi A8 measures up.
Even before you get in, the doors have an amazing sense of solidity and quality. It’s like opening and closing a bank vault… if that huge circular door had a power-assisted soft-close function.
There’s copious amounts of space for the driver and front passenger with lots of storage including a lidded box between the front seats, complete with a two-piece longitudinally split top design, so you can sneak your half’s open without displacing your neighbour’s elbow.
The door bins are decent but there isn’t a specific cut-out for bottles, so it’s more a case of laying them down than standing them up. There’s also a handy covered cubby at the end of the door armrests.
The glove box is a good size and there are two cupholders under a pop-up cover in the centre console.
Of course, the back is where space really counts, and there’s as much room as you’d find in, well… a limo.
Sitting behind the driver’s seat, set for my 183cm position, I enjoyed copious amounts of head, shoulder and legroom.
There are electric sunblinds for the rear and rear side windows, controlled by buttons in the door as well as the rear seat remote, a 5.7 inch OLED display housed in the beautifully trimmed fold-down centre armrest (which also has a soft close function!). The remote also allows adjustment of the lighting and climate control. Classy.
There’s a shallow storage box and twin cupholders in the armrest, medium size door bins and hard shell pockets on the front seat backs. The rear armrests also feature a small lidded cubby.
In terms of connectivity and power options there’s wireless Android Auto and Apple CarPlay, a USB-A and USB-C in the front, and an identical pair in the rear, as well as a 12-volt socket in the front and two in the back.
Boot volume is a useful 505 litres (VDA) and the lid is electric, with gesture control. It’s able to easily swallow our three-piece luggage set or the bulky CarsGuide pram. And while the rear seats don’t fold there’s a ski port door to accommodate long items. Just make sure you use the tie-down anchors in the boot to ensure they’re properly secured. There’s a handy netted section behind the left wheel well and a cargo net is included.
Maximum towing capacity, for a braked trailer, is 2.3 tonnes (750kg unbraked) and in more good news, the spare is a space-saver rather than the increasingly prevalent inflator/repair kit.
As an electric vehicle, the e-tron has certain advantages over its combustion equivalents, and overall makes for an accomplished family-sized SUV. But there are areas where more could be done to take advantage of its high-voltage features and abundant footprint.
Up front in the cabin is a good place, with both occupants treated to lavish seats with plenty of head and legroom, great adjustability, and plenty of width in the cabin.
The finishes are beyond premium with thick chunks of well-padded leather meeting your elbows, hands, and knees at every point. As always the lovely Audi switchgear exists in most places, but the removal of solid toggles and buttons in favour of an extra touch panel feels unnecessary.
There’s still a physical volume knob, and while the climate touchscreen is plenty large enough to have a shortcut button for every function without needing a sub-menu, it feels like you have to move your eyes too far from the road to know you’re going to jab it in the right spot.
Even the main touch panel has an interesting haptic feedback effect for each press, designed to mimic the solidly-sprung button hardware the brand has used in the past.
The screen looks amazing and is fast and sharp, key hallmarks of computer hardware that's up to the task, although the resolution is so high the touch elements when using Apple CarPlay end up being a little small and hard to stab at while you’re trying to keep your eyes on the road.
For storage there’s a big bottle holder and bin in the doors, a large cutaway with a storage tray, dual bottle holders, and power outlets in the centre, with a further smallish storage area under the armrest console.
Unlike some EVs there’s no huge cutaway under what was traditionally considered the transmission tunnel, although there is a small bay with the USB-C ports.
The rear seat feels good for space, with an almost flat floor and decent legroom and width, although headroom could be better.
There are netted pockets on the backs of the front seats and decently-sized bottle holders in the doors, with a further set in the drop-down armrest.
The quad-zone climate with its own touch panel and adjustable centre vents is a nice touch in the rear, as is the set of USB-C ports below. The hard backings to the front seats and built-in sun blinds our car had will even be great for kids.
The boot measures in at 660 litres, which is high for the segment. It fit our three-piece CarsGuide demo luggage set with room to spare, and that's despite the massive battery pack under the floor.
There’s auxiliary storage, too, with a further bay under the boot floor and a second small tray situated under the bonnet, both useful for keeping your charging paraphernalia.
With an entry price of $202,700, before on-road costs, the A8 is in the thick of it amongst its full-size primo sedan competitors from Europe and Japan. Specifically, BMW’s 740i MHEV ($272,900), the Lexus LS500h ($195,920), Maserati Quattroporte GT ($210,990), Mercedes-Benz S450 ($244,700) and Porsche’s Panamera ($207,800).
By definition, a luxury car should be loaded to the gunwales with features that make life on the road that little bit easier. And aside from the performance and safety tech we’ll cover shortly, the highlights from a very lengthy standard equipment list are - 20-inch alloy rims, metallic paint, adaptive cruise control, digital matrix LED headlights, digital OLED tail-lights, full keyless entry and start, power-assisted door closing, power boot lid (with gesture control), a panoramic sunroof, heated, ventilated and massaging electrically adjustable front seats, heated front armrests and extended leather trim (centre console, door rails and armrests, steering wheel and upper dashboard).
Also included are ambient interior lighting (with 30 colours and six colour profiles), four-zone climate control, electric sunblinds for the rear and rear side windows, ‘Audi Connect’ navigation and multimedia (with voice and handwriting recognition), wireless Android Auto and Apple CarPlay, 17-speaker 730-watt Bang & Olufsen audio (with digital radio) and a colour head-up display.
There’s a lot more, and the A8 can hold its head high in terms of pricing and features relative to its $200K price tag and the competition.
A base, before-on-road costs asking price (MSRP) of $168,400 for the e-tron S in SUV form puts this sporty model a step above two of its most notable rivals, the Mercedes-Benz EQC (currently tops out at $141,300), and Jaguar I-Pace (currently tops out at $155,550), but below the menacing, full-fat BMW iX M60 (at $222,900), or the incoming updated Tesla Model X Plaid ($206,449).
To be fair here, only the iX M60 and Model X are pitched as performance variants in their respective ranges, with the Mercedes and Jaguar lacking either an AMG or SVR model respectively to represent their performance line-ups.
To that end, the e-tron S ups the ante when it comes to its power output with an impressive 370kW/973Nm across three motors, two at the rear, and one at the front. More on this in the Drivetrain part of this review.
Suffice it to say, it’s a lot of power. The e-tron is high-spec across the range, too, with the S scoring massive 21-inch alloy wheels, ‘Valcona’ leather interior trim, a heavily digitised cabin consisting of a 12.3-inch digital instrument cluster, 10.1-inch multimedia touchscreen, and a second 8.6-inch touch panel for the car’s climate functions.
The e-tron S also gets wireless Apple CarPlay and Android Auto connectivity, with matching wireless phone charger, built-in navigation, a 16-speaker Bang and Olufsen sound system, full LED lighting for the head and tail-lights and throughout the cabin, quad-zone climate control, heated front seats with power adjust, and a panoramic sunroof.
Finally, the S also has performance enhancing features like progressive (variable ratio) steering and adaptive air suspension.
Obviously, with the high level of standard gear, there’s not as much to put on the options list, although our car also had the weird $3500 ‘Virtual Exterior Mirrors’ which grant it concept-car like cameras with adjustable touch-panels inside the car in place of standard wing mirrors.
I don’t like these, but Audi says nearly half of all e-tron buyers are choosing them. More on this later.
There’s also the option to upgrade the car’s AC charger from 11kW to 22kW which could be very appealing if you have a public station nearby capable of putting out such power. This option will set you back a further $6900.
The last item on the list is the 'Sensory Package' ($9600) which bundles improved Matrix LED headlights in with soft close doors complete with puddle lamps, extended Nappa leather trim in the cabin, rear sunshades and heated rear seats. Our car had this option pack, too.
The Audi A8 50TDI is powered by a 3.0-litre turbo-diesel V6 engine sending 210kW (from 3500-4000rpm) and 600Nm (from 1750-3250rpm) to all four wheels via an eight-speed automatic transmission (with ‘Tiptronic’ sequential manual shift function) and Audi’s quattro constant all-wheel drive system using a self-locking centre differential.
It also features a 48-volt electrical set-up for mild hybrid functionality built around a belt connected starter/generator, AC to DC converter and a 48-volt lithium-ion battery.
With energy recovery of up to 12kW from regenerative braking, it enables the A8 to regularly coast with the engine switched off and helps the extended stop-start system to operate smoothly.
The S-branded e-tron sets itself apart from the rest of the range with a seriously powerful set of three motors. There are two on the rear axle, and one on the front axle.
The total combined output of this collection is 370kW/973Nm, which for a combustion car, would be unprecedented.
To be fair, these figures are under a ‘boost’ mode, with the car generating a still strong 300kW/800Nm in most situations.
The three motor drivetrain allows for an electric version of Audi’s ‘quattro’ all-wheel drive system which the brand says can react to changes in 30 milliseconds and move torque appropriately.
The system is rear-biased, and in the name of efficiency the front motor is only used when required under acceleration or cornering.
Audi’s official fuel economy number for the combined (ADR 81/02 - urban, extra-urban) cycle is 6.6L/100km, the 3.0-litre turbo-diesel V6 emitting 175g/km of CO2 in the process.
Over a week of city, suburban, and some freeway running we averaged 11.1L/100km, which is acceptable for a 2.1-tonne luxury sedan.
Also worth noting the standard stop-start system works beautifully thanks to the 48-volt starter/generator.
You’ll need 82 litres of diesel to fill the tank and using the official number, that translates to a range of just over 1240km, which drops to around 740km using our real-world figure.
The e-tron may be electric, but it’s also a performance car. To that end, its energy consumption, relative to the field, is behind the pace.
In fact, at a whopping 27.8kWh/100km, driving the e-tron around feels like the electric equivalent of steering a big V8.
It produced one of the highest consumption numbers I have seen from any EV during my time with it. Considering this number is even below the WLTP consumption number, which is 28.4kWh/100km, that's not great.
For comparison, the Mercedes-Benz EQC's official number is just 20.8kWh/100km, while the Jaguar I-Pace consumes 21.2kWh/100km according to the WLTP procedure.
Yes, they aren’t performance cars in the same sense, but it’s still a big difference.
I made sure to take it out and stretch the e-tron’s legs to assess its performance in its more sporty driving modes, but the majority of my time with the car was spent in a more comfort-oriented setting and with the regenerative braking set to maximum.
Possibly as a result of its real-world consumption, my car was showing about 350km of range on a full charge, a little below the official WLTP number of 364km, although it is worth noting the enormous 21-inch alloys do their part to reduce the range. The car ships with 20-inch wheels in Europe.
The good news is the e-tron is capable of charging fast, with its max DC charging speed set at 150kW (allowing for a 5.0-80 per cent charge time for its 95kWh battery of 30 minutes), and its AC charging speed set at 11kW, which allows a slow-charging time of around seven hours.
If you intend to park on the street or live in a unit where installing charge infrastructure is impossible, I would strongly recommend you consider the 22kW AC charging upgrade which will cut the AC charge time in half.
While there are few public stations currently capable of the full 22kW in Australia, it will future-proof your car for ideal convenience charging for when they're more commonplace.
Despite extensive use of aluminium in the ‘ASF’ platform and body panels, the A8 tips the scales at a sturdy 2095kg, yet Audi says the A8 will accelerate from 0-100km/h in just 5.9 seconds. And with 600Nm of peak torque available across a flat plateau from 1750-3250rpm this big four-door gets up and goes hard when asked to.
At more sedate speeds you’re occasionally reminded there’s a diesel engine under the bonnet, with that characteristic engine and exhaust noise only making their presence felt under pressure.
In fact, under normal circumstances, noise, be it the engine, tyres or wind is minimal, thanks to a combination of the car’s aero-efficient shape, thick acoustic glass and other sound-deadening measures throughout the car.
The eight-speed auto transmission is suitably smooth, with the central shifter or wheel-mounted paddles able to make snappy sequential ‘manual’ shifts.
There are four drive modes in the ‘Drive Select’ system - ‘Comfort’, ‘Auto’, ‘Dynamic’ and ‘Individual’ - enabling tweaks to the steering, transmission, throttle and suspension. Comfort felt most appropriate most of the time, although dialling up the throttle and transmission to more aggressive modes in Individual adds an enjoyable edge.
The suspension is five-link front and rear with an adaptive air system smoothing even high-frequency bumps and ruts amazingly well.
Push into a corner and the A8 feels nicely balanced, its wide track, sophisticated suspension, plus the quattro AWD system seamlessly distributing drive between the front and rear axles, keeping the big body under control. In fact, you feel the ‘big car shrinking around you’ syndrome from the get-go.
The steering is precise without being overly sharp and road feel is good. Again, with that 2.1-tonne kerb weight in mind, braking is appropriately powerful with big ventilated discs front (350mm) and rear (330mm).
It pays to remember the turning circle is 12.5m, and it’s worth picking your spot for a U- or three-point turn.
Although there’s a lot going on for the driver in terms of screens, buttons and switches it all makes sense ergonomically. The head-up display is helpful and there’s a common sense mix of digital and physical controls, the latter including an audio volume knob. Yes.
Does the e-tron live up to the promise set by sporty Audis which have come before it? The answer is interesting.
There is no doubt the e-tron S is rapid, at times absurdly so. If you stick it in the required S mode and hunker the suspension down, planting the accelerator makes its claimed 0-100km/h sprint time of 4.5 seconds suddenly very real.
It lurches ahead without so much as a squeak from its enormous tyres, grabbing the road with its front axle as it warps you forward.
So yes, this electric performance car is no doubt quick. It is also heavy. Weighing in at a tare mass of 2830kg, the e-tron S is quite literally massive.
The trouble is, while its powerful electric motors are great at overcoming this gravitational obstacle in a straight line, it’s in the corners and at low speeds where you feel every bit of it.
The e-tron crashes over larger bumps, it’s suspension struggling to deal with the combination of its weight and low-profile tyres, while it can also feel cumbersome in the corners around town.
The suspension is better at levelling things out once you gain a bit of pace, and the tyres work with the all-wheel drive system to put in a Herculean effort when carving up bends at speed, but there’s the ever-present lurch of weight always working against you.
This feeling isn’t helped by the steering tune, which even in its most comfort-oriented setting feels hefty and slow to turn. In the default sport mode, ‘dynamic’, it takes effort to push this car around corners.
Despite the unsettling feeling of it, though, the car holds on for dear life, and I never once felt as though the tyres were remotely in danger of breaking traction when put under pressure.
Is it a performer, then? Absolutely, there’s something mind bending about a vehicle so heavy going so quickly.
Does it feel fun to drive? Less so. I enjoyed the connectivity of the Porsche Taycan offers at speed more than I enjoyed the e-tron S, and its weight and girth demand a nice wide piece of tarmac for you to really wring it.
It’s far from a darty and engaging car like the Q5 can be despite its mammoth power outputs.
Elsewhere, the drive experience feels very Audi, though. The touchpoints and feedback are mostly familiar, as are the software and ergonomics.
The virtual wing mirrors are more of an inconvenience than anything else. This car is already hard to see out of, with big C-pillars and a tall belt line, and the digital exterior mirrors offer what feels like a limited angle of vision and make it extra hard to see out at night.
Some things fall to the wayside a little. The e-tron’s drive system almost hides the regenerative braking setting several menus deep, which, once activated, allows you to set it using the paddle-shifters on the wheel.
Audi says the regen will account for nearly 30 per cent of the car’s range, which is odd because even at the highest setting it feels a bit mild, relying on the user to manually operate the brake for a ‘blended braking’ mode to make up the difference.
It’s a bit of a stretch from the single-pedal driving modes offered on some rival cars.
My theory here, as with this car’s look and feel, is the e-tron is primarily designed to be familiar to an existing Audi customer, or someone coming out of a purely combustion premium rival.
Even though the A8 hasn't been assessed by ANCAP, as you might expect, it goes to town when it comes to active safety tech, the car’s standard crash-avoidance features including auto emergency braking (AEB) (pedestrians/cyclists - 5.0-85km/h, vehicles - to 250km/h), ‘Active Lane Assist’, blind-spot monitoring, a reversing camera and 360-degree view (including kerb view function), front and rear parking sensors, ‘Collision Avoidance Assist’ (steering assistance in critical situations), ‘Turn Assist’ (monitors incoming traffic when turning right), and rear cross-traffic alert.
There’s also ‘Intersection Crossing Assist’, ‘Attention Assist’, tyre-pressure monitoring and an ‘Exit Warning System’ (detects cars and cyclists when opening doors).
If all that isn’t enough to avoid a crash the airbag count runs to nine, including front and side bags for the driver and front passenger, side airbags covering the outer rear passengers, full length curtains and a front centre airbag to minimise head clash injuries in a side impact. A first aid kit, warning triangle and high visibility vests are also on-board.
There are three top tethers for baby capsules/child seats across the back seat with ISOFIX anchors on the outer positions.
The regular e-tron range is considered very safe by ANCAP which awarded it a maximum five stars with strong scores across all categories in 2019, although it does exclude the S which was not released at the time of testing.
The S has the same suite of active safety features as the rest of the range, though, which includes freeway-speed auto emergency braking (up to 250km/h) with pedestrian, cyclist detection, and intersection assist, lane departure warning with lane keep assist, blind-spot monitoring with rear cross-traffic alert, adaptive high-beams, adaptive cruise control (with eco-assist and stop-and-go functions), as well as a clear exit warning.
The 360-degree camera suite is welcome, as is airbag coverage for the front, side for both front and rear rows, as well as curtains.
ISOFIX points feature on the rear outboard seats, and there are top tethers across all three rear seats.
The A8 is covered by Audi Australia’s five-year/unlimited km warranty, which is now par for the luxury market course, and 24-hour roadside assistance is included for the duration.
Paint defects are also covered for five years, with rust (to the point of perforation) covered for 12. Nice.
Service is required every 12 months or 15,000km with a five-year capped-price plan for the A8 coming in at $3830, or $766 per year. That’s a fair wedge but not outrageous for the category.
Audi has followed its Volkswagen parent in upgrading its warranty to five years and unlimited kilometres, finally leaving BMW and its three-year warranty behind.
The e-tron’s high-voltage battery components are covered by a separate eight-year and 160,000km warranty, but the big win, especially in this premium segment, is the first six years of servicing (covering three 24 monthly or 30,000km visits) is free.
Oh, and your public charging is largely free for the same period too, as Audi throws in a six-year ChargeFox subscription.
Six years pretty much cost-free? Audi, how far you’ve come.
