Audi E-Tron vs Audi S8

What's the difference?

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 S8's existence is a source of joy for me because it's not a huge SUV. Yes, it's a huge sedan but it's a reminder that the technological flagship is alive and well, at least in Germany. And the important thing about these cars is the way the toys filter down through the rest of the range. That used to take years but we're seeing this cool stuff a lot more quickly, right down to the A1.

The S8 punches, and punches hard in this rarefied part of an already shrunken section of the market - the twin-turbo V8 matches its German rivals, it's lighter and it's as well-stacked as any of the three. What it doesn't do, however, is shout about itself the way the other two do.  It's the incognito choice.

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.

The sheetmetal is obviously very restrained given it's an Audi first, and secondly, it's just not done to go wild in this part of the market.

It's an A6 that's joined a gym, but didn't join that weird gym with men that can't run after you when you insult them (don't ask how I know this). Rolling on 21-inch wheels as standard, you can go up to massive 22s if you so choose.

The A8 created a subtle redirection of Audi's passenger car look, with the updated A4 and A6 both picking up on the horizontal bar between the rear lights and the huge grille framed by family lights with signature DRL patterns. The S8 builds on that with subtle S cues but nothing even vaguely shouty.

The interior acreage - or 'cabin', if you will - is very comfortable, but you already knew that. The multi-screen layout was first seen in the A8 and has now found its way into A7, Q8 and Q7 and is, as ever, brilliant to look at and use.

The MMI updates that have found their way into other cars are present and correct. Like the exterior, it's very restrained but not to the point of sparse minimalism, despite the lack of switches and buttons.

I really don't like the steering wheel, though, and I can't put my finger on why. It certainly isn't especially sporty-looking but I wonder if the standard flat-bottomed S wheel just looked stupid.

The materials are beautiful and everything fits together perfectly.

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.

The cabin is clearly built with rear seat passengers in mind, with rear leg and headroom configured for those continent-crossing drives.

The S8 has plenty of comfort for two rear seat passengers and a few amusing options to while away the hours in traffic or on the autobahn.

That doesn't mean the front seat passengers are in purgatory, with huge but supportive seats adjustable in all conceivable directions.

Front and rear rows score a pair of cupholders and bottle holders while the boot is a handy, if not awe-inspiring, 505 litres.

For $260,000 there is a lot to get through, as there is on the less sporty A8. Start with huge 21-inch alloys, 17-speaker Bang & Olufsen stereo, panoramic sunroof, matrix LED headlights with laser lights, soft-close doors, acoustic glazing, leather trim, S front seats, extra leather over the A8, Alcantara headlining, carbon inlays, four-zone climate control, heated and cooled front seats, 'Virtual Cockpit' with S mode, and a tyre repair kit.

You also get active suspension, a sport version of the 'quattro' all-wheel drive system (with a sport differential), and a walloping great twin-turbo V8 to get you moving.

A massive touchscreen on the centre stack (familiar in Q8, A7 and Q7) hosts Audi's 'MMI plus' system, which is very good and does away with the console-mounted rotary controller. It also has wireless Apple CarPlay to go with the console-bin wireless charging pad. Android Auto is still USB. 'Audi Connect plus', now in full-featured glory, is also along for the ride.

Another technical highlight is the active noise cancelling which is meant to reduce the noise in the cabin the same way noise cancelling headphones do.

There's a clever rear seat remote control, which is a little detachable tablet to allow those who are being chauffered to faff around with various settings.

Our car had the $13,900 'Sensory Package', which adds a 1820-watt B&O 3D sound system with 23 speakers, electrically adjustable outer rear seats along with heating, cooling and massage function, and full leather.

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.

Under that long bonnet is a 4.0-litre twin-turbo V8 pumping out 420kW and a diesel-like 800Nm of torque. 

That's a lot, even for this big bruiser. Obviously, being an Audi S-car, it has quattro all-wheel drive, which is fed by an eight-speed ZF automatic. Which is in everything now. Well, just about.

That huge torque figure is available between 2000rpm and 4500rpm while peak power arrives at 6000rpm. The 0-100km/h sprint is despatched in - gulp - 3.8 seconds.

As it's riding on the MLB platform, the mild hybrid system is a 48-volt set-up. A lithium-ion battery in the boot takes charge from the belt alternator/starter, which means the S8 can coast at higher speeds with the engine off and also cut out at 22km/h and under in traffic.

The system can also add up to 60Nm of torque in the right conditions for up to six seconds, and if it happened for me, I didn't notice it.

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. 

The 10.5L/100km official figure is, shall we say, optimistic. The launch drive was mostly highway so there's no real information to be gleaned from that, so we'll have to wait for real world fuel figures.

I'd say 12-13L/100km is achievable if you don't like having fun, in which case, the lesser A8 is probably for you.

Audi says the MHEV system saves 0.8L/100km with an early cut-out for the stop-start and the ability to coast on the highway for over half a minute at a time.

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.

Driving any of the cars in this segment is a rare treat, whether it's the 'entry level' diesel or this top of the heap sports sedan. My day with the S8 was filled with the usual surprise and delight that only these tech-packed cars can deliver.

Heading out of the Sydney CBD in 'Comfort' mode, the car scans the road ahead and adjusts the active suspension accordingly. You already know it has active suspension because when you pull the door handle, the car lifts by 50mm to make it a bit easier to get in.

The suspension's party trick is flat-topped speed bumps - drive at one, brake a little and sense the way the body feels like it stays exactly where it is in the air but the suspension almost completely flattens the speed hump.

It's uncanny and almost unnatural, with just the tiniest change in altitude and no noise from the suspension.

It also manages the terrible narrow lanes of CBD thoroughfares with ease, the lane keep system letting you know if you're straying.

On to the motorway and you get a feel for its crushing performance. You won't hear much, though - the stereo's noise-cancelling system shuts out almost all tyre noise and consistent wind noise is largely banished, too.

I'm going to admit I gasped when I found some corners. Active suspension bodes well for the tricky stuff, as does the all-wheel steering. Both are exceptionally clever systems for making the car feel a lot smaller in town and in car parks but they're also really good if you want some fun.

But the way the rear-wheel steer adds agility to such a big car is hilarious and clever. While you can't quite chuck it around - and really, you're not buying an A8-sized car for that kind of nonsense - brisk progress is far from intimidating.

Now, obviously, a Ford Fiesta would drive away from the S8 in the really tight stuff but it would take some time to properly shake it. The colossal torque from the V8 hurls even this two-tonne-plus limo out of the corners in a most satisfactory manner.

It's surprisingly agile for a machine more than five metres long and two metres wide. If your passengers are corner enthusiasts, you'll all be having fun in near silence. It's oddly engaging to be moving at pace in such a hushed cabin.

The S8's considerable safety equipment list includes nine airbags, ABS, stability and traction controls, forward AEB (up to 250km/h), reverse cross-traffic alert, lane departure warning, various collision mitigation and protection systems, exit warning, lane keep assist, active cruise control and on, and on, and on.

The rear seat's centre airbag is terribly clever, popping up between passengers to stop you knocking heads. Another clever trick is the way the car detects a side impact is about to happen, boosting the height of the side about to cop it to try and get the sills to take more of the impact, rather than the door.

Given the relatively niche status of the A8, let alone the S8, there is no ANCAP crash test or safety rating. One imagines given the ton of safety gear a five star rating is all but assured. Even the US IIHS gave the A8 a miss.

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.

Audi continues to fail to match Mercedes move to a five year warranty, sticking with three year/unlimited kilometre cover. BMW is still doing it too, so maybe Ingolstadt and Munich are playing chicken. 

You can get a five-year service plan for the S8, coming out at $3990 for the duration.
