Volvo C40 vs Audi RS6

What's the difference?

The C40 becomes a compelling option in the electrified small SUV space, offering a premium look and feel, great range and tech inclusions at the price, as well as awesome on-road dynamics.

Its main downsides are the rear seat, which is compromised by its platform and design-led roofline, and the overwhelming power and added traction of the dual-motor makes the single motor less attractive on the value front.

Still, regardless of variant chosen, the C40 looks to offer a stand-out balance of price, range, and performance, against its traditional rivals and newcomers alike.

To me at least, the RS6 is pretty much the ultimate fast and practical car. One which is just as comfortable plodding around town as it is tearing it up on the track. Keep in mind, too, this may be one of your last chances to have a car which looks like this, equipped with a V8 engine. So, have I convinced you? Would you consider one of these over a performance SUV? Tell us what you think in the comments below.

Volvo has become a brand with a distinctive and consistent design language which embodies the kind of beautiful minimalism normally associated with Scandinavian brands.

I have always liked how Volvo says more with less design elements, with only gentle touches of chrome or gloss black, and a lack of over-the-top sporty pieces avoiding the temptation to over-sell the sporty potential of the brand’s range.

The C40 takes the small SUV formula, well established by its XC40 relation, and gets a bit weird and experimental. It’s slightly lower and has a more coupe-styled rear, with a strongly raked rear window giving it a sportier and more aggressive look than the rest of Volvo’s SUV range.

The styling is sold by an angular spoiler piece running atop the boot, and the rear light clusters have gone all minimalist, constructed of individual pieces rather than a single transparent housing, and they give a nod to the C30 hatchback which this car is the spiritual successor to, by name and nature.

The interior offers up no surprises, sticking to the formula Volvo has established across all of its current models. An effortlessly premium space with, again, a minimalistic dash dominated by the portrait touchscreen, the C40’s premium nature is confirmed by its finely patterned inlays, simple chrome pieces, and abundance of soft-touch surfaces.

The big upright vent fittings with clever rhomboid patterns on their adjustment dials are always a highlight piece of modern Volvos, and the pattern work is continued on the central volume adjust dial and even on the little rotating pieces of the light and wiper stalks. Clever.

Even the software is paired back on the multimedia suite and digital dashboard, with easy to use shortcuts and simple menus which suit the car.

Volvo might turn off some buyers with the more unconventional shape of the C40. But for those looking for a more traditional SUV it also offers the XC40 in the same two variants, and the Polestar 2 caters to those not looking for an SUV at all.

At a distance the RS6 is just an unassuming station wagon, but the closer you get, the more apparent it becomes how mean it is. It’s wide, it’s chiselled, it’s not just good looking, it’s iconically Audi.

The stance is so wide, its ride height so low, and its wheels are so massive that any keen eye will be able to spot where the difference is between this and any old family hauler.

Wagons may not be trendy, but there’s something undeniably cool about having the hauling capacity of an SUV at the ride height of a sedan.

Of course, if you want to look even more svelte and don’t need the boot space, the RS7 is always lurking around at a slight price premium.

Inside, the RS6 has all the modern amenities of the Audi range. Expect the usual sharp screens, lovely sports seats, and a tasteful application of textures throughout.

There’s a blend of carbon-look finishes, chrome, leather and gloss black. Perhaps a little too much gloss black to keep clean, but the aesthetic is suitably upmarket. 

You can go to town on customisation, and the car we primarily tested had stitching and colour in the carbon patterns to match its 'Ascari Blue' exterior, but you can pick whatever shade or combination of colours your budget allows.

Audi’s software is pretty good these days, with an attractive theme and fast hardware to back it, and the brand’s ‘Virtual Cockpit’ is still one of the most aesthetically pleasing and customisable digital instrument systems on the market, despite being one of the first.

The C40 is essentially a XC40 with a cropped down roofline, and there are some obvious downsides which this new shape brings.

The front seat throws no surprises, though, offering plenty of room for two adults with a welcome level of adjustability for the seat and wheel. The seats could be more comfortable, though, with a notable lack of padding in the base compared to some luxury (or even non-luxury) rivals. 

I’m a fan of the fabric trim which comes on both grades, bucking the trend of needing to have leather or leather-like trim for a car to feel ‘premium’.

The ample window space up front, including the massive glass roof helps the C40’s cabin feel spacious, but the view out the rear with its aggressive design is all but a very limited letterbox aspect, particularly if the rear seat headrests are in the upright position. 

While some controls are exclusively via touch interface, there is a physical volume dial, and shortcut buttons for the defogger functions. 

Temperature is controlled by touch, however, and the detail settings have some smaller toggle adjustments. Tricky to jab at when you’re on the move.

The digital dash is refreshingly simple, but minimally adjustable, with the choice of either a nifty navigation screen, a blank screen, or trip details being the only options.

Cabin storage is good but not stellar. There are bottle holders and big pockets in the doors, a set of two cupholders in the centre (beats the Polestar 2’s single cupholder), a small tray with a wireless charger under the multimedia screen, and a smallish console armrest box.

The rear seat is where the real problem exists. Unlike the XC40, the C40’s cropped roofline means my head was hard up against the roof (I’m 182cm tall). 

I did have decent knee room behind my own seating position, however the seat comfort in the back still isn’t as good as some rivals. 

The middle position is also compromised, thanks to the raised centre floor piece the C40’s platform needs to facilitate all-wheel drive in its combustion relations.

A bottle holder appears in each door pocket, and in a rare inclusion, there are heated outboard rear seats, adjustable air vents, and USB-C charging ports.

The boot has a quoted capacity of 413 litres with the rear seats up. The floor is comparatively high suggesting a smallish space when loaded with luggage cases, for instance. Stay tuned for a follow-up review so we can see how well it holds our three-piece demo set.

The floor itself has an adjustable, pop-up divider and multiple luggage hooks, making it quite versatile, and there is a cavity beneath which can hold your charging cables as well as the inflator kit in place of a spare wheel.

Okay, I promised a car with the practicality of an equivalent SUV, but it’s not quite there. The trade-off is still worth it, I promise, but there are a few areas where the RS6 isn’t as practical as you think it’s going to be, particularly for front occupants.

Yes, it’s a big wide car, with large but supportive seats and plenty of headroom, but the issue for those travelling in the front two seats is the surprisingly limited amount of storage.

Yes, there are two bottle holders in the centre console with a folding tray lid to hide them away, but they aren’t huge. Bigger bottles would have to go in the door bins, but even then they’re a bit height-constrained.

There’s a decent glove box on the passenger side, but even the centre console box is very shallow, with more than half of it taken up by a wireless phone charger.

The touch panel for the climate unit looks impressive but still can’t match having physical dials. It has clicky haptic feedback to your individual presses, and all the functions are permanently accessible instead of hidden in sub-menus, so if you’re going to make climate a touch-based interface, it doesn’t get much better than this.

Where the RS6 shines is in the back seat. Despite those big bucket front seats, I had heaps of room behind my own seating position (at 182cm tall), with lots of headroom and sufficient width in the cabin to spread out.

You sink into the rear seats, which are heavily contoured so riding in the back is a pretty good experience even on the track.

Rear passengers get four adjustable air vents in both the B pillars and in the centre, as well as their own touch panel for the rear climate zone.

USB power outlets are also available, and there are netted pockets on the front of both back seats, with a further two bottle holders in the drop-down armrest.

The centre seat is probably only good for kids, because there’s a very tall raise in the centre required for the driveshaft, eating all the legroom.

The boot is fairly large at 548 litres which is in mid-size SUV territory, although I will admit some performance SUV rivals offer closer to 600L.

Space expands to 1658L with the second row folded flat.

Let’s start with the bad news. Most people can’t afford one of these. The RS6, in all of its muscular glory, is more expensive than ever before. Now wearing a before-on-roads price-tag of $241,500, it’s hardly your average mum and dad family hauler. But then, there’s nothing average about the RS6.

It’s so well regarded amongst enthusiasts for multiple reasons. It’s the biggest meanest wagon you can buy, and somehow Audi has managed to make this version more powerful and even faster than before.

In fact, it’s one of the few normal looking combustion cars out there which can still hold a candle to many electric cars, with its whomping V8 helping it warp from 0 to 100km/h in just 3.4 seconds.

More on those performance specs later. If you’re wondering what else you get for your near-quarter-of-a-mill it’s pretty much every spec item Audi currently offers.

There are now lighter 22-inch alloy wheels, adaptive air suspension, a high-performance braking system, an RS-specific exhaust system, matrix LED headlights with adaptive high beams, a 10.1-inch multimedia touchscreen with navigation and wireless phone mirroring and one of the best digital instrument clusters on the market.

It also features Valcona leather interior trim, sporty bucket seats with perforated trim, honeycomb stitching, as well as ventilation and heating, additional cabin trim in synthetic suede (comprised of 45 per cent recycled fibres), ambient interior lighting and a panoramic sunroof.

It’s a lot of stuff, but one thing you get a little less of is sound insulation. Audi has chosen to remove some of it this time around so you can hear the V8 better from behind the wheel.

Great news here, the C40 can be chosen with two powerful layouts, either a front-wheel drive 170kW/330Nm set-up, or a dual-motor all-wheel drive arrangement, able to make use of nearly double the power at 300kW/660Nm. The dual-motor is capable of sprinting from 0-100km/h in just 4.7 seconds.

The front-drive is backed by a 69kWh battery allowing it a 434km range, while the dual motor ups the battery size to 78kWh to allow a 420km driving range.

The RS6 is still packing eight cylinders in 2023, producing a massive 463kW/850Nm, somehow an increase (+22kW/50Nm) over the previous iteration.

Audi’s signature ‘Quattro’ all-wheel drive system is present alongside a limited-slip differential and four-wheel steering.

Air suspension and performance brakes and exhaust also feature, alongside an aggressive Continental SportContact 7 tyre package.

The 0-100km/h sprint time is now just 3.4 seconds, allowing you to show up even some electric cars, and the RS6 features 48-volt mild hybrid technology with a cylinder-on-demand system which can shut half the block down for more efficient coasting.

The transmission is an eight-speed torque converter unit which is smooth and effortless.

Surprisingly, energy consumption is quite high for both C40 variants. The single motor is the more efficient of the two, consuming 16.8kWh/100km on the more lenient ADR testing schedule, while the dual motor officially consumes 22.2kWh/100km to the same standard. I saw around 23kWh/100km overall in my short test of the dual-motor variant.

Energy consumption could be better for both, as I have achieved more consistently impressive results particularly from Hyundai and Kia electric cars.

Where the C40 is more impressive though is its charging specs, which are exactly where they need to be for a car this size. On a rapid DC charger, the C40 can charge at a rate of 150kW meaning a 10 - 80 percent charge in 40 minutes for the dual motor, or 32 minutes for the single motor.

On the slower AC standard, the C40 charges at a rate of 11kW. Expect a 10 - 80 percent charge time of around five or six hours on this standard. 

The C40 uses a European-standard Type 2 CCS charging port, although it misses out on the handy two-way charging feature offered by some rivals.

Officially, the RS6 and its eight cylinders drink a combined 11.8L/100km, although even with its fancy hybrid system and cylinder deactivation, my time with the car saw 15.0L/100km. The RS6 has a 72-litre fuel tank and takes only the finest 98RON unleaded fuel.

If you’ve driven any kind of XC40 or even a Polestar 2 before, the C40 will offer no surprises. It’s pretty much exactly the same from behind the wheel with a few subtle tweaks.

This is a very good thing. The C40 is quiet, easy to drive, and its electric motor and regen system offer a smooth single-pedal experience.

It is also alarmingly, overwhelmingly, rapid. While its massive set of batteries under the floor make it feel heavy off the line in stop-start traffic, sticking your boot into the accelerator will remove any doubt, particularly in the dual-motor variant, that this Volvo means business.

The dual-motor also has an incredible torque-vectoring system, making it extremely difficult to elicit so much as a squeak from its tyres. It also feels as though torque is distributed quite evenly between its two driven axles, making it feel neither prone to over- or understeer.

This has the effect of making the C40 feel somewhat indestructible in the corners, with absurd levels of grip. 

The same feeling is present in top-spec versions of the Polestar 2, only the feeling of ever-present weight is more noticeable in the higher-riding C40, which can make it unsettling to take corners at the kinds of speeds it is capable of.

The steering tune is interesting. Volvo offers two software-controlled modes, either heavy or standard, and the standard mode is heavy enough. 

Despite its electrical assistance, the wheel does continue to offer some organic feedback, making the C40 a pleasure to steer on countryside roads.

The ride is also surprisingly good, despite massive wheel options. I was impressed how easily the C40 handled most bumps and undulations, communicating little to the cabin. 

The ride can approach its limits with such big wheels and the weight of its batteries, generally these are communicated via unsettling thuds from underneath the car. Regular undulations at higher speeds also had the C40 bouncing around a little.

On the whole, though, the cabin is kept relatively insulated and serene, adding an element of total confidence, similar to that offered by Teslas, whilst offering better ride quality with a softer edge. At higher speed, at least on the 20-inch wheels, road noise does pick up, however.

In terms of electric driving, there is a single adjustable setting for regen. The car either offers a full single pedal mode with maximum regenerative braking to bring the car to a halt with the motor alone, or a ‘standard’ mode which tones the regen down and offers it blended in via the brake pedal. 

Single pedal mode is more efficient. I suggest you stick to it if you want to make the most of this car’s efficiency.

I was surprised to have so few complaints about the C40’s drive experience. This is a balanced and capable EV which is yet another example of how even vehicles which use combustion platforms are improved out of sight by full electrification.

As you might have guessed from its impressive engine and performance equipment, the RS6 is a certified weapon on road and track.

On the road you can expect a quiet, refined cabin, superbly balanced steering for low and high speeds and a gentle ride quality courtesy of the pricey air set-up.

It’s as noisy or as quiet as you want it to be, with the cylinder deactivation toning things down at low speeds, and the engine roaring to life under heavy acceleration, or when the 'Dynamic' drive mode is selected.

It can at times be alarming how much the RS6 leaps to life, as it feels so cushy in a city, its width and cabin giving the feel of a luxury car rather than a performance one.

Make no mistake, though, the RS6 is properly quick, and when you give it a kick, it’s the roaring, aggressive machine the spec sheet suggests.

The best place for this? The track, of course. The big V8 and the capability of the all-wheel drive system are truly best explored at velocities impossible to legally achieve on the road.

Once you get past the bark and snarl of this wagon’s eight-cylinders at full force, and the lightning-fast shifts of its eight-speed automatic, you’ll have a moment to appreciate the way it simply holds to the tarmac when you tilt it into the corners, providing a balance when loaded up which only air suspension can provide.

The steering is awesome, communicating the texture of the road nicely to the driver, and requiring just the right amount of force to keep the car pointing where it needs to go.

The grip level is astounding with the huge tyres and the four-wheel steer system lets this hefty wagon take corners at a tighter angle than your brain initially allows.

Thankfully, the four-wheel steer system isn’t weird, either. While it can have a strange effect on some cars, in the RS6 it only bends your mind slightly when you tip it into a hairpin. Otherwise it feels pretty normal.

When everything is warmed up, it can let its guard down slightly and allows the driver to eke out a slide at the rear here and there for extra fun-factor

Jeez. What a machine. I guess this is what a quarter of a million dollars buys. A car that can do it all. Take the kids to the school in comfort and tear it up on the track like few other passenger cars on the same day.

There’s a caveat, though. A small one which looks like it will turn into a big one for cars like this in the near future.

I had the opportunity to drive the RS e-tron GT around the same circuit and it was better. Much better.

It was faster, more accurate, more composed. It was so effortless, I didn’t realise exactly how much quicker than the RS6 it was until I drove them back-to-back.

It’s a good sign for the future, but also a reminder a V8 like this isn’t the performance pinnacle it once was.

Like its standard cabin equipment, the RS6 has had the entire catalogue thrown at it for active safety gear. Included is freeway-speed auto emergency braking with pedestrian, cyclist, and intersection detection, lane keep assist with lane departure warning, blind-spot monitoring with rear cross-traffic alert, an exit warning system, and adaptve cruise control with traffic jam assist.

Elsewhere the RS6 gets dual front, dual side, and head curtain airbags, with ISOFIX points on the outer two rear seats as well as three top-tethers across the rear row.

The RS6 is not safety rated by ANCAP, but the rest of the A6 range was awarded a maximum five stars in 2018. 

The C40 is covered by Volvo’s five year and unlimited kilometre warranty, with a separate eight-year, 160,000km warranty for the battery. There is also eight years of roadside assistance attached.

It is pleasing to see the service intervals for the C40 are long, as they should be for an electric car with so few moving parts, set at two years or 30,000km. 

The first 24 month service is free of charge, and Volvo tells us service pricing after this period will average out to around $100 a year ($200 per visit).

Five years and unlimited kilometres is the warranty length, and Audi’s ownership program includes invites to events like the one we were able to experience for the launch of this car. A track-test of the RS6 and the RS e-tron GT.

If you own one, I recommend them, you’ll learn a thing or two about the car and possibly yourself while you’re at it.

Servicing is required once every 12 months or 15,000km, and a service pack covering the first five years or 75,000km can be purchased alongside the car at a cost of $4360.

It works out at $872 per year, which isn't economy car cheap, but with such a complex drivetrain, what did you expect?
