Volvo XC90 vs Audi A8

What's the difference?

It’s a credit to Volvo that the XC90 feels like a new car, even with its older underpinnings. This latest update has successfully addressed areas that needed the most attention, namely the multimedia system, interior and exterior design. The electric driving range now feels somewhat old school compared to the numbers some manufacturers can achieve these days. A lot of PHEVs now exceed 100km EV range and buyers are starting to expect that. And setting up the third row takes way too much effort to want to do it regularly. The new Volvo XC90 is a comfortable, engaging and properly premium family SUV and the updates have only improved what was already a solid offering.

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.

Back in early 2015, I attended the international launch of the second-generation Volvo XC90. At the time I thought it was a handsome SUV, with Volvo successfully interpreting what is essentially a big people-hauling box on wheels with typical Scandinavian flair.

There’s been a facelift since then, but this latest refresh brings the XC90 bang up to date.

New elements include a modern take on the 'Thor's Hammer' LED headlights, and a new bonnet and grille with an updated diagonal logo spread across the car's face. At the rear the only change is slightly darker tail-lights.

The new grille in particular looks great, and with all of the blacked-out elements of the T8 - grille, lower air intakes, parts of the apron, mirror caps, roof rails and window surrounds - it looks quite cool, especially contrasted with the test car's 'Crystal White' paint. It has elevated the overall look.

Inside, Volvo has made big changes, mostly with the dash and console. It retains the familiarity of other Volvos, but is much more in keeping with its new all-electric EX90 sibling.

It still has a horizontal theme, but with cool new vertical air vents. The new multimedia screen fits well into the dash layout, and isn’t over sized. It’s the ideal size at 11.2 inches. There are a few buttons underneath but not many.

The mix of materials used at the front of the cabin includes ‘Grey Ash’ wood, piano black, chrome, metal-look speakers, grey fabric and soft touch as well as hard plastics. It sounds like it would be too much but it works well.

Volvo has always been a leader when it comes to car seats and the new XC90 is no exception. The beautifully designed ventilated charcoal Nappa leather seats look and feel stunning. The tiny Swedish flag is a nice touch, too.

The engine start/stop button and the crystal selector add a touch of glamour to the cabin. Overall, the XC90 feels properly premium inside, still with a Scandinavian bent. Just lovely.

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?

Any dedicated seven-seat family SUV needs to nail practicality and when it comes to the Volvo XC90, there are clear pros and some surprising cons.

One of the many pros is the seats. As mentioned, they look schmick, but are also supremely comfortable and offer the perfect level of bolstering and support. The T8 has a seat adjustment memory function that can be programmed into the driver profiles that also tailors other functions to suit different drivers.

The quality of the materials and build quality of the cabin is largely impressive. Even the damping of the indicator stalk has a feeling of high-end quality.

Volvo’s digital instrument cluster is clear and easy to navigate, once you work out what the buttons on the steering wheel do. They don’t have words on them so it takes a while. The driver’s manual comes in handy for this.

The big story in the cabin is the new 11.2-inch multimedia display. Volvo uses a Google platform and the car comes with Google Services which includes Google Assistant voice control, Maps and Play.

I’m a fan of Apple CarPlay and once I have assessed a car’s in-house multimedia system I often defer to CarPlay. It’s simple and familiar. But aside from using CarPlay to connect once, I used Volvo’s system for the vast majority of my time with this car.

Logging into your Google account means your favourites come up on the map and there is no downside to functionality. If I had the car for longer I would've added Spotify to the system and logged into that, too, but I was happy listening to digital radio on the phenomenal 19-speaker Bowers & Wilkins sound system.

The screen takes some familiarisation, but once you understand the home keys and how to switch between apps, it’s a pleasure to use. It has a clear layout, nice graphics and is responsive. Yes, the air con controls are mostly housed in the screen, but if you tap the lower part of the screen the entire climate menu appears. It is light years ahead of Volvo’s previous screen set-up.

Most functions are housed in the screen, although there are buttons just under the screen for volume and audio on/off, front and rear demisters, hazard lights and a button to open the glove box.

Storage up front is just okay. The console houses shallow cupholders and a handy upright phone holder, as well as the device charging pad. It’s a shame there’s no under console storage, but the transmission tunnel might be too chunky for that.

The shallow central bin houses two USB-C ports and a 12-volt outlet. Bottle storage is decent in the front door cards.

The panoramic sunroof only has a sheer blind (it’s powered) which is less than ideal in a country like Australia. It’s been fine in winter but I’m curious to know what it’s like in the height of summer.

The second row features manual window blinds to keep your little ones cool.

There’s some back support for the second-row seats but the base is flat. Some of the seat fabric in that row looks like it doesn’t quite fit, but I think that’s the nature of the leather with the intricate designs.

In terms of space, there’s ample leg, toe and headroom, and the rear backrests recline for extra comfort on long trips. The bases roll forward and back and the seats are split 40/20/40.

Kids will likely fight over who has to sit in the middle seat because the combination of an intrusive transmission tunnel and the rear of the front centre console protruding into the space means it is not a great seat.

Occupants have access to chest and knee-level air vents, heated seat and digital climate controls, map pockets, two USB-C ports and a central fold-down armrest with a fiddly cupholder mechanism. The rear doors will only house small, narrow bottles.

Accessing the third row of the Volvo is challenging. For starters, to move the second row seats forward you need to use the lever at the top of the seat and the roller under the base to move them. And they are heavy seats. That leaves just enough of an aperture to get into the third row.

But first you have to raise the third row. Sadly there’s no lever in the boot area to quickly raise or lower the third-row seats. You have to either climb into the boot and reach for the lever at the top of the seats, or reach through the back door and try and raise them that way. And again, they are heavy.

It is a deeply unintuitive system and leaves you exhausted and frustrated. Especially when you consider other seven seaters have a much more functional and lightweight third-row arrangement.

Once in the third row, it’s clear it is for humans with tiny legs only. It is not a space appropriate for six-foot tall men like me, even for short distances. You do get ample headroom, air vents, cupholders and storage boxes on either side that open up to show a kid-friendly spider web design with a friendly looking spider. Cute!

The seats fold flat into the boot floor and the loading lip is level with the floor so loading heavy or long items should be a breeze. You can adjust the air suspension from the boot to lower the height further which is always a handy feature.

It comes with a solid cargo blind but you need to remove it if you want to raise the third row. When putting it back in, it catches on the third-row seat belts, so it’s not the best design.

In terms of boot features, the Volvo comes with a household charging cable that is housed neatly under the boot floor in a stylish bag. Many PHEVs and EVs still don’t have a dedicated spot to house a cable so you have to take up boot space with a chunky cable bag. Good job, Volvo.

It has a powered tailgate, a few nooks and a pair of 5.0kg hooks. However, it doesn’t have a spare wheel of any description. Just a tyre repair kit. This is due to packaging restrictions, but it’s never an ideal solution.

In terms of space, the Volvo can swallow 640 litres of cargo with the second row up and 301L with all three rows in place. That latter figure isn’t bad compared to some seven-seaters.

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.

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.

Two powertrains are available in the new XC90, both with all-wheel drive.

The B5 Bright comes with a 2.0-litre four-cylinder turbo-petrol engine with 48-volt mild hybrid assistance offering 183kW of power and 350Nm of torque. It can dash from zero to 100km/h in 7.7 seconds.

The version I’m testing has a 233kW, 2.0-litre four-cylinder turbo-petrol engine with a plug-in hybrid system that uses a 107kW electric motor and an 18.8kWh, 400-volt battery.

The total system output for the T8 PHEV is 340kW and a meaty 709Nm. It uses an eight-speed automatic transmission. It can complete the 0-100km/h sprint in a brisk 5.3 seconds.

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 mild-hybrid XC90 B5 Bright has an official fuel use figure of 8.1 litres per 100 kilometres, which is on the thirsty side, although it is a 2.5-tonne SUV.

Officially, the XC90 T8 Plug In Hybrid sips just 1.8L/100km on the combined (urban/extra-urban) cycle, but as with any PHEVs, unless you charge your car religiously and never drive far enough to deplete the battery, that figure is extremely hard to achieve.

I charged the car regularly using my home wall charger (two to three hours for a full charge) and the fuel gauge barely moved.

After a week of mixed driving my final fuel economy figure was 3.4 litres per 100km, which isn’t too bad.

The XC90 T8 has a 3.6kW onboard charger and a Type 2 plug so it’s only capable of AC charging. It is not compatible with a DC source so no fast charging on the go.

The official electric driving range according to Volvo is 77km, which feels a little old school compared to the many PHEVs landing on the market now that have an EV driving range in excess of 100km.

The offical figure also seems somewhat optimistic because the most I got on a full charge was 60km. Anecdotally, I have heard it can get up to 70km after a charge, it just didn't get there in my time with the XC90.

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.

For a tall, large and heavy SUV, the XC90 has an excellent driving position. You feel hunkered down in the driver’s seat; it’s almost sporty!

Those healthy power and torque figures translate well on the road. It is properly quick off the mark and picks up pace rapidly when already at speed. You do need to work out the trigger point for the accelerator because if you give it too much it feels a little like a slingshot.

The transition between the electric motor and the petrol engine is noticeable, but it’s still smooth. It’s not harsh or clunky like some hybrids and PHEVs. Similarly, the eight-speed transmission is so smooth it rarely makes its presence felt. It's a lovely match for this powertrain.

On that, the cabin is incredibly well insulated. It’s a hushed ride at any speed. Again, you’ll hear the engine kick in but it has a nice note so that noise is welcome.

The powertrain has several driving modes including 'Pure' (EV only), 'Power' (for added performance) and 'Hybrid'. Hybrid is the go-to and 'Auto' allows the system to determine when the petrol engine kicks in. This is the best everyday mode.

Volvo understands the XC90 is more than just family transport and has engineered it in such a way that it offers a surprising level of dynamism.

It’s flatter in corners and bends than you expect of a car of this size and weight. It has a balanced chassis, likely helped by the air suspension, with minimal body roll and little lateral movement inside. Impressive.

It has enough grip on looser surfaces, aided by the all-wheel drive set-up.

The ride quality is more composed and refined at higher speeds, regardless of the road conditions, managing potholes and the like quite well. Volvo has tweaked the suspension tune as part of the update for this very reason.

At lower urban speeds, it’s not quite as calm. You’ll feel speed bumps and potholes and it's a little jiggly on rough surfaces. The low profile (275/35 R22) tyres are partly to blame here.

With that said, it’s not enough to dampen the overall XC90 drive experience. It is a lovely car to drive, whether cruising on freeways, country road blasts or city commuting.

Its underpinnings might be 10 years old, but the XC90 feels as fresh to drive as many of its rivals.

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.

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 XC90 is covered by Volvo’s five-year, unlimited kilometre warranty, and the servicing schedule is every 12 months or 15,000km, whichever comes first. These are similar terms to other premium brands in Australia.

Buyers can opt for one of two capped-price servicing packs, costing $2380 for three years and $3870 for five years.

This pricing is a little more than the BMW X5 but quite a bit more affordable than the Mercedes-Benz GLE.

The Swedish brand used to have a reputation for over-priced servicing but it’s sharpened up its offer considerably in recent years.

Volvo has around 40 dealerships located across Australia and conducts its servicing in-house at the dealer.

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.
