Audi A6 Avant e-tron Review

With every manufacturer seemingly betting everything on the continued popularity of SUVs, it’s reassuring that at least some are still building traditional bodystyles such as estate cars. The Audi A6 Avant e-tron is one of the clearest signs that the electric switch doesn’t have to mean giving up on that sort of car.

Underneath, the A6 Avant e-tron uses Audi’s electric PPE platform, shared with the Q6 e-tron and developed to deliver the things that matter most in a premium EV: strong range, rapid charging and a more polished overall driving experience. What makes the A6 Avant e-tron more interesting is that it wraps all of that in a shape that’s genuinely useful. This is not just a sleek electric fastback with a token estate badge. It has a proper load bay, a big hatchback opening and the kind of practicality Audi buyers will expect from an Avant.

Audi has also resisted the temptation to make the design too radical. The blanked-off grille and cleaner surfacing make it clear that this is a different sort of A6 Avant, but it still looks recognisably like an Audi estate rather than an EV experiment. That is likely to matter to the sort of buyer who wants an electric executive car without the visual drama some rivals bring.

There’s a broad spread of versions too. The rear-wheel-drive entry-level e-tron is joined by the longer-range e-tron performance, the all-wheel-drive quattro and the much quicker S6 Avant e-tron. For most buyers, though, the appeal is less about the fastest version and more about the way the car combines long-distance comfort, smooth electric performance and very usable practicality.

There are compromises to be aware of. Rear space is acceptable rather than exceptional for such a large car, and a few cheaper plastics lower down in the cabin take a little edge off the premium feel. Even so, the Audi A6 Avant e-tron is a highly convincing electric estate. It feels carefully judged and impressively complete.

Like the idea of an electric A6, but would sooner have something with a bit more of a saloon silhouette?  Take a look at our Audi A6 e-tron review. 

For most buyers, the Audi A6 Avant e-tron performance is the sweet spot. It gets the larger 94.9kWh (usable) battery, the strongest official range figures and more than enough performance for a car like this. With up to 445 miles of range depending on trim, it's the version that best captures what the A6 Avant e-tron does so well.

The regular rear-wheel-drive e-tron still makes sense if price matters more than outright range, but it gives away too much battery capacity to feel like the best fit for a premium electric estate. At the other end of the line-up, the quattro and S6 are very appealing if you want extra pace and traction, but they move the focus away from the car’s strongest qualities of comfort, effortlessness and long-distance usability.

In trim terms, S line will likely be enough for plenty of buyers, while Black Edition adds the stronger visual impact many will want. Vorsprung is hugely well equipped, but it's also the point where the Audi starts to feel very expensive.

Prices start at £64,390 for the Audi A6 Avant e-tron Sport. S line is £67,890 and Black Edition £70,490. Move up to the A6 Avant e-tron performance and those figures rise to £70,660, £74,160 and £76,760 respectively, with Vorsprung joining the range at £79,515.

The quattro versions start at £75,760 in Sport trim, rising to £79,260 for S line, £81,860 for Black Edition and £84,615 for Vorsprung. If you want the S6 Avant e-tron, prices begin at £94,150 for Black Edition and rise to £101,650 for Vorsprung.

That is serious money, although the BMW i5 Touring is pitched in much the same part of the market. The Volkswagen ID.7 Tourer remains the more affordable electric-estate alternative, even if it cannot match the Audi’s badge appeal or cabin finish.

The clearest alternative is the BMW i5 Touring. It has the same broad brief of premium electric-estate usability, and it remains the more obvious choice if you want a slightly more engaging drive. The Volkswagen ID.7 Tourer is also hard to ignore, because it offers a lot of the same long-range electric-estate logic for less money, even if it cannot match the Audi’s sense of occasion.

If you’re willing to move away from estates, the Porsche Macan Electric is relevant because it shares much of the underlying hardware and brings a more driver-focused flavour, while the Audi Q6 e-tron offers similar Audi EV thinking in SUV form. That said, the Audi A6 Avant e-tron makes a particularly strong case precisely because it's not another SUV. It offers real load-carrying ability without the extra bulk or visual heaviness.

That gives it a slightly unusual niche. It’s not the cheapest electric family car, not the sportiest premium EV and not the most spacious thing for the money. But as an all-round executive estate with serious range and very fast charging, it sits in a sweet spot few other cars currently hit.

If you’re buying a large estate, you’ll expect it to deliver properly useful space, and the Audi A6 Avant e-tron does a decent rather than class-leading job here.

The boot is flat and offers 502 litres of space with the rear seats up. That’s a useful figure, but it trails the BMW i5 Touring’s 570 litres and the Volkswagen ID.7 Tourer’s 605 litres. Fold the rear seats and capacity rises to 1,422 litres, or 1,330 litres in the S6. There’s also a 27-litre front boot across the range, which is useful for cables and smaller items.

Up front, there’s unlikely to be much complaint. The seating position is comfortable, adjustment is generous and there's plenty of room. In the back, space is acceptable but not exceptional. Headroom and elbow room are fine, but the raised floor means your knees sit a little higher than ideal. The upside is that the flat floor gives decent foot room and avoids a central tunnel for the middle passenger.

So the Audi A6 Avant e-tron is practical enough for family use and long trips, but if outright luggage room is your main priority, key rivals still do this bit better.

The Audi A6 Avant e-tron is 4,928mm long, 2,137mm wide and 1,527mm high, with a 2,946mm wheelbase. Those numbers put it squarely into big executive-estate territory. 

In practical terms, that means plenty of road presence and a strong sense of substance without the height or visual bulk of an SUV. It also explains why the car feels so stable and relaxed on faster roads. The long wheelbase and wide stance give it a planted, expensive feel that suits the brief very well.

Infotainment provision is strong even in the least expensive trim. Every version gets an 11.9-inch digital instrument display and a 14.5-inch central touchscreen with DAB radio, Bluetooth, navigation, wireless Android Auto and Apple CarPlay, plus a wireless charging pad.

The screens are clear, the graphics are sharp and the touchscreen responds quickly. There’s also the option of a third display for the front passenger, which lets them control navigation, audio and climate functions, while also viewing video content hidden from the driver.

Where the system falls down slightly is that almost everything is controlled by touch. That means taking your eyes off the road more often than ideal, and the lighting controls on the driver’s door are especially fiddly to use on the move. The technology is impressive, but it’s not Audi at its most intuitive.

The A6 Avant e-tron gets a strong mix of premium-feeling and more sustainable materials. Audi highlights Cascade cloth and other partly recycled finishes, along with leather-free options for key touchpoints such as the steering wheel.

The important thing is that the cabin still feels expensive. The trim choices are modern and understated rather than flashy, and the better combinations do a good job of making the car feel contemporary without losing the plushness buyers want at this level. Higher-spec versions also add richer trim details, more ambient lighting and generally stronger visual drama.

There are four main power levels in the Audi A6 Avant e-tron range, and the step between them is more about breadth of ability than simply chasing bigger numbers. The standard rear-wheel-drive A6 Avant e-tron is the entry point, with enough performance to feel brisk in everyday use and more than enough pace for a car of this type. It is the least powerful version, but it still does not feel slow.

The A6 Avant e-tron performance is the one most buyers should start with. It keeps the same rear-wheel-drive layout but brings a worthwhile lift in power, while also being the range leader in the line-up. That gives it the strongest case as the default choice, because it combines the long-distance ability this sort of electric estate really needs with the kind of effortless performance buyers will expect at this level.

Above that sits the A6 Avant e-tron quattro, which adds a second motor at the front for four-wheel drive. That brings a clear step up in pace and gives the car more traction and security in poor conditions, though with a small trade-off in range compared with the performance model. It is the better fit if you want stronger acceleration or simply prefer the reassurance of all-wheel drive.

At the top of the range is the S6 Avant e-tron. It is usefully quicker again, but not so different in concept that it turns the A6 e-tron into a sports estate. Instead, it feels like the most powerful expression of the same idea: a fast, refined and quietly capable electric executive estate. The key point is that every version is comfortably quick enough. The real decision is whether you want the longest range, the extra traction of quattro or the added pace and image of the S6.

The Audi A6 Avant e-tron is at its best as a refined, long-distance electric estate. It is not trying to be an overtly sporty driver’s car, but there is still enough precision and composure here to stop it feeling remote. In fact, it feels tidier and more assured than a Mercedes EQE, while still delivering the calm, easy-going character most buyers in this class will actually value more.

That relaxed nature is a big part of the appeal. The A6 Avant e-tron feels stable and confidence-inspiring at motorway speeds, and it covers ground with the kind of quiet, low-effort polish you would hope for from an Audi executive car. Refinement is particularly strong, with very little powertrain noise, low wind noise and a generally hushed, expensive feel on longer journeys.

It is less engaging than something like a BMW i5 Touring or Porsche Taycan Sport Turismo if outright driver appeal is your priority. The steering is light, and higher-spec cars on larger wheels can feel firmer because adaptive damping is not widely available across the range. But judged on its own terms, the A6 Avant e-tron feels well resolved. It is comfortable, impressively refined and very easy to live with, which is exactly what many buyers will want from an electric estate like this.

The Audi A6 e-tron achieved a maximum five-star rating from independent safety organisation Euro NCAP in 2025, and that result applies to the broader model line including Avant versions. Euro NCAP praised the car’s adult and child occupant protection in particular, with especially strong child-protection scores. 

Audi also fits a strong suite of standard and optional driver-assistance systems, including the usual emergency braking and lane-support features, along with parking and traffic-assistance technology designed to make a big car easier to live with. The safety story here is exactly what buyers will expect from a new Audi at this level: strong, current and reassuring.

Charging is one of the Audi A6 Avant e-tron’s biggest strengths. The 75.8kWh battery can charge at up to 225kW on a DC charger, while the 94.9kWh versions step up to 270kW. Despite the difference, both can charge from 10 to 80% in 21 minutes under ideal conditions.

On AC charging, both battery sizes can charge at up to 22kW. Using Audi’s quoted times for an 11kW connection, a full recharge on a typical 7.4kW home wallbox will take about 12 hours for the smaller battery and around 14 hours 30 minutes for the larger one.

If you can charge at home on a strong EV tariff, running costs should be impressively low for a car of this size and performance.

Audi’s standard new-car warranty is three years or 60,000 miles. For the battery, Audi provides an eight-year or 100,000-mile battery degradation warranty on fully electric models. 

That is about what buyers now expect in this class rather than especially generous, but it's reassuring enough. Audi Approved Used examples also come with a minimum of 12 months’ warranty; the A6 Avant e-tron looks likely to become quite an interesting used buy once early cars begin filtering through in bigger numbers.

Insurance groups start at 42 for the entry-level versions and rise to the highest possible group 50 for high-end models, so cover is unlikely to be cheap.

That is no surprise given the car’s price, performance and repair costs, but it's worth being clear that this is firmly premium-executive EV territory rather than anything close to affordable family-car insurance.

Annual tax is relatively high after year one. Because every Audi A6 Avant e-tron sits well above the expensive-car threshold, it attracts the Expensive Car Supplement on top of the standard annual VED rate in years two to six. That means a total of £640 a year during this period, before dropping to the standard rate (currently £200 a year) after that

So while it's electric, this is not a car with especially low annual tax costs. Buyers should budget for a relatively hefty yearly bill during those early years of ownership.
