Audi RS6 vs Ford Mustang Mach-E

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.

The Mustang Mach-E is fantastic to drive and very competitive on the range and equipment front, allowing it to outpace some of its well established rivals in Australia.

In fact, it's almost a shame about the Mustang name, because it will distract from what is, at its core, a compelling first step for Ford into the fully electric space.

So, don’t expect a ‘Mustang’, at least not in the traditional sense. But this is certainly something. A new future for a new Ford.

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 Mach-E looks good, but nothing like the designs you have come to expect from Ford.

Sure, there are plenty of notes, references and hints, to its Mustang namesake, some more hidden than others, but fans will have to accept this is a new interpretation of the badge for a new era, and at the end of the day, it’s an electric mid-size SUV.

The overall visage is a little more sleek than your average RAV4, though, with a long wheelbase, coupe-like rear, and a curvy shape which no doubt helps it cut through the air as efficiently as its shape will allow.

Mustang hints are found, obviously, in the big pony badge on the front, but also the frowny-face headlight profile, and iconic three-bar pattern for the rear lights, too.

There are even hidden things, like pony imprints on the underbody protection, and ‘electric ponies live here’ branded onto the motor unit, where few buyers will likely ever see it. In a move which should keep all Mach-E owners happy, every grade looks great, each having its own character.

The base car looks all aero with its wheel covers and more humble plastic cladding pieces, while the Select adds contrast piano black bits and more traditional alloy wheels.

The GT goes harder still with a 3D-effect grille and much more Mustang-like 20-inch wheels.

I’m not sure what I was expecting when it came to the Mach-E’s interior, but it looks a bit more ordinary in pictures than it does when you’re in the car.

What appears from a distance to be a hodgepodge of bits from Ford America and Ford Europe with the same dull grayscale theme is more nuanced and textured once you’re in the driver’s seat.

I especially like the tiered dash with the speaker-bar look for the Bang & Olufsen system which integrates across the front, and the 15.5-inch screen which looks like it will dominate the space is actually at a perfect distance from the driver.

An appreciated amount of soft-touch surfaces and synthetic leather finishes round out the space. There is even a grade-specific textured detail piece running across the dash. Nice touch.

It’s also a lot to take in, but somehow it works. One thing is for sure though, it’s not traditional ‘Mustang’. This has jumped from the big, brash, old-world (and often maligned for quality issues) interior, to something cleaner, more open and futuristic.

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.

This is especially true when it comes to the usability of the cabin. I was surprised to be greeted by a high seating position, a wide cabin, and an abundance of storage with plenty of neat features.

For a start, the centre console is a nice piece of design. It features a floating bridge section with a wireless charging bay, rubberised storage tray, dual bottle holders with variable edges, and a floating armrest piece with a large console box below.

In front, and below the wireless chargers, there’s a big cutaway for additional storage, and a decent sized glove box on the passenger side.

The all-dominating touchscreen, as mentioned, is at a nice distance from the driver, isn’t as obstructive as it looks and unlike the Tesla Model Y or Model 3, the Mach-E scores a little digital instrument panel to provide the driver with conveniently-located core information.

I only have two gripes about these systems. Unfortunately, you have to adjust the climate functions through the touchscreen.

There’s a nice central volume dial, but it would be nice to have physical adjustment dials for temperature and fan speed, too.

As it is, the touch areas are quite small, and require a bit of concentration to jab at.

The instrument panel has a nice clean design, but isn’t customisable, the limited information it shows is all you get. Better than not having one, I suppose.

The rear seat is also excellent, offering me, at 182cm tall, plenty of airspace for my knees, and sufficient width for my arms. Headroom is its most limited dimension, although I fit without my head touching the roof.

The seats are brilliant, clad in a decent synthetic leather material and padded with an excellent amount of foam material for a comfortable ride no matter where you’re seated. The centre seat even seems usable for adults, thanks to the Mach-E’s flat floor.

Rear passengers are treated to bottle holders in the doors, two more in the centre drop-down armrest, USB ports on the back of the centre console, pockets on the backs of the front seats, and a pair of adjustable air vents.

Annoyingly, the huge panoramic sunroof doesn’t have a retractable shade, nor is there a flexible shade accessory on the options list.

Sure, it looks great, but it could be a nuisance, baking the interior during hot Australian summers.

For some reason this particular trait is common in more and more EVs with the Tesla Model Y and Polestar 2 sharing the same issue.

Boot space is 402 litres (VDA) which is not particularly large for a mid-size SUV. I would expect 450 litres or more in this category, but the Mach-E is compromised a little by its aggressively-shaped rear.

It also doesn’t get a spare wheel of any kind, making do with a repair kit under the floor.

Ford also throws in a Type 2 to Type 2 public AC charging cable, but if you plan on charging from a wall socket at home you’ll have to delve into the accessories list.

One of my favourite Mach-E features is the 134 litre frunk. I’ve said before I don’t think this particular EV fad is super useful.

It’s often an inconvenience to have to pop the front from the inside, and I’ve found in my long-term loans of EVs I rarely use them, but the Mach-E’s frunk is special because it’s watertight and drainable.

This opens up some neat opportunities, like the ability to throw dirty hiking, diving, or work equipment in there and hosing it out later, or even filling it up with ice and chucking a case of drinks of your choice in there for an old-fashioned American block party. It even has integrated cupholders for this express purpose.

Price is key to any new electric car, and the Mach-E doesn’t do anything unexpected. It’s not here to be a new, more affordable mid-sized electric option in Australia, instead leaning on its performance credentials to slice out its own niche amongst its competitors.

Three Mach-E grades arrive in Australia with prices ranging from $79,990 for the most affordable rear-wheel drive Select version, stepping up to $91,665 for the also rear-drive Premium and stretching to $107,665 for the all-wheel drive GT.

Before you start adding on-road costs or state-based discounts then, the Mach-E competes with mid-grade or higher-end versions of the Hyundai Ioniq 5, Kia EV6, Tesla Model Y - and maybe the more sedan-like Polestar 2.

Range is, of course, key to the price equation for any EV, and this is where the main differences lie between the variants, which are remarkably similar when it comes to standard equipment. The base Select gets a smaller, more affordable 71kWh battery pack. It grants the entry-point car a driving range of 470km on a single charge. Not bad at all.

Next up, the Premium grade remains rear-wheel drive, but swaps up to a larger 91kWh battery unit, delivering one of the longest ranges of any EV on the Australian market, at 600km.

Finally, the top-spec GT moves to all-wheel drive, almost doubling its power outputs, but maintains the same 91kWh battery, for a reduced but still respectable range of 490km between charges.

Standard equipment is impressive, too. Even the base Select scores items usually reserved for high-spec cars, like synthetic leather interior trim with heated and power adjust front seats, a panoramic sunroof, and a Bang & Olufsen 10-speaker premium audio system.

Other standard equipment includes the impressive 15.5-inch portrait-oriented multimedia touchscreen with wireless Apple CarPlay and Android Auto connectivity, a matching wireless phone charging bay, a 10.2-inch digital instrument cluster, 19-inch alloy wheels (with aero panels), a 360-degree parking camera, LED headlights, and the full safety suite.

The Premium grade scores higher-spec LED headlights, contrasting piano black exterior trim, black headliner and red stitching for the interior, as well as metal scuff plates and pedal trims.

The top-spec GT has the most noticeable bump in equipment, with the addition of adaptive suspension, 20-inch alloy wheels, a Brembo brake package, GT styling touches inside and out, ambient interior lighting, and sporty front seats with additional bolstering.

The issue the Mach-E faces, then, is not range or standard equipment. It is simply not offered in a form which is as competitive with price-leading versions of its core rivals.

Of course, most anticipated vehicles like this are picked up primarily in high-grade forms to begin with, Ford telling us nearly 40 per cent of pre-orders have been for the GT, but it’s notable there’s no circa-$70,000 entry-point variant as there is for the EV6, Ioniq 5, and Model Y.

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.

The Mach-E might not look like a traditional Mustang, but don’t be fooled, it’s no ordinary mid-size SUV on the performance front.

Even in its most basic trim level, the Mach-E puts out 198kW/430Nm, and yes, it’s rear-wheel drive.

The mid-grade version boosts power even further to 216kW/430Nm, while the top-spec GT nearly doubles outputs to 358kW/860Nm thanks to its dual-motor, all-wheel drive system.

Sprint times are a hot-hatch baiting 6.6 seconds for the base Select, 6.2 seconds for the Premium and an impressive 3.7 seconds for the GT.

The GT scores other enhancements, too, like the 'MagneRide' suspension also seen in the internal-combustion Mustang, and upgraded software unlocking the sportiest ‘Untame Plus’ drive mode which Ford says is ‘for track use only’ (and it is, because it basically turns traction control down to a minimum). 

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.

As mentioned, the three Mach-E variants have distinctly different range offerings. The base Select travels a respectable 470km between charges, the mid-grade Premium covers 600km (one of the longest ranges on offer from any EV currently in the Australian market) and the top-spec GT travels 490km between charges.

Interestingly, the base car is offered with the more affordable LFP (lithium-iron phosphate) battery chemistry for its 71kWh unit which uses less rare materials, sourced from China’s CATL, while the larger 91kWh batteries are sourced from Korea’s LG Chem using the higher output but more expensive NMC (nickel-manganese cobalt) chemistry.

On the efficiency front the Mach-E isn’t bad considering its performance, and size. The base Select is rated at 17.8kWh/100km on the combined cycle, while the number is lower for the Premium at 17.3kWh/100km, but hops up to a less-than-impressive 21.2kWh/100km for the all-wheel drive GT.

For reference, these official consumption figures are about on-par with the Ioniq 5 and a little lower than the EV6. It will be interesting to test this car’s range and efficiency figures at a later date, on a longer test.

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.

Let’s make one thing clear. The Mach-E does not drive like a Mustang. A Mustang, of course, being characterized primarily by its brash V8 roar, gratuitous cabin and grand touring dynamics.

No, the Mach-E immediately reminds me of a Ford Europe SUV. Sounds like an insult doesn’t it? But it isn’t.

The Escape and Puma are remarkably sharp to drive, and I consider them deeply underrated options in the SUV space, and more suited to drivers than they first appear. 

The Mach-E takes the best elements of these two and dials it up to 11, adding the smoothness of an electric powertrain and inherent rear-wheel drive performance characteristics as it does.

While it saddles you with a tall SUV-like seating position, it’s no simple SUV once you get it on a few curves, the urgent performance from the rear-mounted motor, even in the base car, is excellent, feeling as though it punches above many of its rivals, while the sharp, accurate steering makes it feel surprisingly agile and responsive considering its dimensions and weight.

The regenerative braking is well-calibrated, too, offered in either a one-pedal or more moderate tune, but perhaps the most surprising aspect of this car is its well balanced ride.

Reviews from my colleagues overseas pointed to an overly hard ride, which I was expecting, but I was greeted with a car that deals with bumps, undulations, and corrugations with a remarkable amount of poise.

Ford says what it calls the “Irish tune” was selected as it offered the best ride for our roads, and it seems the Blue Oval engineers weren’t wrong.

It’s a firmer ride than the boaty Hyundai Ioniq 5, but not as firmly sprung as the Polestar 2 or Tesla Model Y.

In other words, it’s firm enough to make it fun to drive, but not hard enough to ruin it in your day-to-day commute.

It was also interesting to find the MangeRide adaptive suspension in the GT grade didn’t make as big a difference as expected, firming things up a little on some surfaces, but offering a slight edge to the amount of chassis control on offer as a result.

The three drive modes also make a significant difference to the experience. The ‘Whisper’ mode dials back accelerator response and artificial noise, serving as a kind of ‘eco’ setting which is said to also be more suited to low-traction scenarios, where the instant torque of the electric motors can easily spin the wheels.

The standard mode is far more balanced, while the 'Untame' mode makes the motors respond in haste, and dials up the artificial rumbling noise, but not to an unpleasant level.

The fourth, ‘Untame Plus’ mode, only available on the top-spec GT, allows the car to, for example, break into a drift when grip is low enough by dialling back the traction control.

It’s designed to allow a little more play and maximise acceleration response for track use. Still, it doesn’t feel as tail-happy as its namesake combustion coupe.

While it appears to be yet another mid-size electric EV, then, there’s something a little more on offer here, and something which sets itself apart from the electric pack by being fun to drive in a way something like a Tesla Model Y isn’t.

The best part is, these unusually engaging dynamics extend beyond the top-spec GT, all the way to the base Select.

The only thing is, it’s still very tidy. It’s organised, the traction control is clever, the chassis is sharp, the steering is brilliant and the electric motors are… inorganic.

In some ways, this car is too good to be a Mustang, certainly missing some of the edge-of-your seat chaos a V8 rear-driven coupe can bring.

So, long as you understand this, there’s a very compelling sporty electric SUV to be found here.

All Mach-E variants get the same set of modern active safety equipment including auto emergency braking at freeway speeds, lane keep assist, blind-spot monitoring and rear cross-traffic alert. It also scores a 360-degree parking camera and reverse auto braking.

Adaptive cruise control features (although not the semi-autonomous ‘BlueCruise’ offered in this car’s American version), alongside a healthy suite of airbags.

Only the Select and Premium grades are rated a maximum five ANCAP stars, with the GT excluded.

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?

Ford offers a now industry standard five-year, unlimited kilometre warranty, as well as the battery manufacturer standard eight-years and 160,000km for the high-voltage components.

Unlike some EVs in this space which push intervals out to two years, the Mach-E needs to see a workshop once every year or 15,000km, whichever occurs first.

Thankfully, servicing is relatively affordable, at just $135 or $180 at alternating years for the first 10 years, and roadside assist is automatically topped up with each service (at an authorised Ford dealer) up to seven years.
