Audi RS6 vs Xpeng G6

What's the difference?

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.

You never know quite what to expect when you jump into the first model from a brand-new brand, but the XPeng G6 was a pleasant surprise. And at this price, with these features, it should really give Tesla Model Y shoppers something to think about.

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.

There’s more than a little Tesla Model Y in the XPeng’s exterior design, with the two sharing the same kind of soft-edged, swept-back SUV styling. 

It helps make the XPeng look familiar and inoffensive, and while I wouldn’t go so far as to call it ground-breaking, I think it has enough exterior flourishes to break up the body work, and I don’t mind the way it looks, and the way it sits on those big alloys.

Inside, it’s a spacious and pretty stylish space. This giant screen is super responsive, and is easy enough to navigate, with the key functions (like climate) glued to the bottom of the screen so you don't have to paw through menus to access them. The idea begins to fail when you have Apple CarPlay or Android Auto active, though, as you have to revert back to the car's home screen to access anything.

The XPeng uses its steering wheel controls to access air-con fan and temp controls as a kind of shortcut, but confusingly they change to distance adjustment when you’ve got the cruise control on. An easier, and much better solution would be to bring back buttons.

I also don't love the stalk-style gear selector, which doubles as a cruise control activator, and, with a double pull, as your autonomous helper. It just feels super old-school in a vehicle this modern.

What is a massive win though is the driver screen. Tesla fans can scream minimalist aesthetics all they want, but the drive experience is simply better when you can see your speed and other key info right in front of you.

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.

At 4753mm in length, 1920mm in width and 1650mm in height, the XPeng fits into the fast-growing mid-size electric SUV space. 

And it ticks a lot of practicality boxes, like with its 571-litre boot, swelling to 1374 litres with the seats folded. But its real party trick is in the back seat, where the space is properly massive. 

I have another mid-size SUV, powered by a petrol engine, at the moment and our baby seat presses against the back of the passenger seat. In this it feels like I could fly a kite in the space between them.

It’s the same for passengers, too. Honestly, the real estate on offer is massive, and that includes for the middle-seat rear passenger, where the lack of a bulky tunnel eating into legroom means adults can sit there comfortably.

There's a pull-down divider separating the back seat that's also home to two cupholders, and there are twin USB connections, as well as air vents (though no temp controls).

There's no spare tyre, though, which means fiddling with the repair kit should you get puncture, or waiting for roadside assist.

Okay, first things first – what the hell is XPeng? It's been around for about 10 years in China, but only made its way to Australia last year. It was founded by some former car company execs and tech tycoons — one of whom is telecommunications billionaire He Xiaopeng, which is where that name comes from.

Anyway, this one is the XPeng G6, which launched in Australia with two trims – the Standard Range, which is $54,800, before on-road costs, and the one we’ve tested, the Long Range, which is $59,800. The difference is in the battery size, of course, but we’ll get to that in a minute. 

As of now, the new Model Y can be ordered for $63,400 for the Standard Range or $73,400 for the Long Range, which makes the XPeng a whole heap cheaper.

Outside, you get LED lighting all around (including the DRLs), a massive glass roof, auto door handles, an auto-opening boot, a V2L connection, which allows you to use your XPeng’s battery to power whatever you plug in and big 20-inch wheels wrapped in Michelin rubber.

You also get some cool high-tech features, accessed through the XPeng app, like the ability to drive your car out of tight parking spots remotely.

Inside, there are synthetic-leather seats that are heated, a heated steering wheel, dual-zone climate, a massive 18-speaker sound system (with speakers in the headrest), wireless charging and two very handy screens — a responsive 15-inch central screen with Android Auto and Apple CarPlay, and a 10.2-inch digital dashboard.

There’s also more safety stuff than you can shake a crash test at, but we’ll come back to that in a second.

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.

This G6 is a rear-wheel drive affair, with a single electric motor housed at the rear axle. It produces 190kW and 440Nm in Standard Range form or 210kW/440Nm in Long Range guise, which don’t sound like massive numbers — especially given the 2.0-tonne-plus weight of this XPeng – but it gets up and moving just fine.

The 100km/h sprint is a claimed 6.2 seconds, while the top speed is 200km/h.

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.

The Long Range version of the G6 nabs a 87.5kWh battery (compared to 66kWh in the Standard Range), unlocking a claimed driving range of 570km. 

The official power use figure is 17.5kWh/100km, but I did a fair bit of driving on all sorts of roads and my number was more like 14kWh.

When it does come time to charge, the G6 is set up for 280kW DC fast charging which means, should you find the right fast charger, a 10-80 per cent charge should arrive in just 20 minutes. Home charging will take a lot longer, of course – we’re talking overnight plugged into a regular wallbox.

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.

How much you love your time behind the wheel of the XPeng G6 comes down to what you're looking for from your mid-size electric SUV.

Speed and sportiness? There's not much of either. But it does serve up tons of space and technology, surprising refinement and a calm and cosseting ride.

And I think you can mount a pretty solid argument that all of that is pretty important in a mid-size SUV, more so than the ability to carve corners.

I did some solid driving in the G6, including a round trip from Sydney to the start of the NSW South Coast, taking in every road type and surface imaginable, and XPeng proved super comfy, pretty quiet and very, very easy the entire time.

Sure, it's not one of those EVs that makes the scenery blur when you put your foot down. Its outputs and acceleration are a bit more user-friendly than that. But it also doesn't ever feel underpowered, with the plenty of poke away from the lights and even some in reserve for freeway overtakes at 110km/h.

The steering, even in its 'Dynamic' mode, is fairly soft, and you can never magic away the weight of the XPeng in corners, where that compliant suspension does allow for some roll, but it also doesn't feel entirely disconnected from the road below in that disconcerting way some vehicles can.

So, if comfort is mission critical in your SUV space, the XPeng delivers.

Oh, and I know that big screens aren't that uncommon these days, but the multimedia unit in the XPeng is a treat. It's super fast, even when scrolling across maps, and it's relatively user friendly, too.

The XPeng G6 wears a maximum five-star ANCAP safety rating from assessment in 2024, owing mostly to a flood of active safety features that arrive as standard, including AEB (with pedestrian, backover, cyclist, motorcycle and crossing detection), lane departure warning, lane keep assist, speed sign recognition, driver monitoring and more.

But it could also lay claim to a unique record – the first Chinese EV in which the safety systems don't make you want to make you pull your hair out with their incessant chiming and bonging.

Only on the freeway, where an intermittent chiming incorrectly warned me I was leaving my lane, were the safety systems at all overzealous. Otherwise, they were entirely liveable.

If a crash is unavoidable, the airbag count runs to seven (dual front, front side, side curtain and front centre) and multi-collision brake is standard, to minimise the chances of a secondary crash following an initial impact.

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?

I'm scoring the regular warranty offering here, which is five years or 120,000km, with the battery covered for eight years or 160,000km. Keep an eye out for deals, though. At the time of writing XPeng was offering a 10-year warranty on both, for example.

Service intervals are 12 months or 20,000km. The cheapest individual service is $238, but over five years the total cost is $2064, averaging out to more like $410 per year.
