Audi RS Q8 vs Ford Mustang Mach-E

What's the difference?

The Audi RS Q8 Performance is a lot - of everything. It offers lots of power, lots of performance, lots of space and lots of luxury. But it’s also a lot of money, and at more than $250k it’s not going to be on everyone’s shopping list. It’s a very niche proposition for a small group of buyers. For those select few, those who want a lot of everything and who crave the ultimate of whatever product they’re buying, then the RS Q8 Performance is going to be a very tempting proposition - even if they never set any lap record in it.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

EV buyers who don’t or won’t see the point of the Mustang Mach-E are missing out.

This is a sporty and fun-to-drive electric SUV in the same way that the Ranger is the sporty and fun-to-drive ute. In other words, a lot of what makes Fords brilliant is alive and well here, without compromising functionality. The opposite of so many Chinese electric SUVs that shine brightest on the showroom floor, then.

Yes, a base Select that is around $10K cheaper to start with might help punters see the light even more clearly (and that's our choice), and it is starting to look dated inside and out, but overall, the Mach-E is an enjoyable, fulfilling and practical family proposition.

We don’t refer to ‘facelifted’ cars for no reason, the RS Q8 Performance has a number of visual changes.

These include a new Audi ‘singleframe grille’ and new front bumper design, with a new Matt Carbon trim package available to highlight that.

There’s also a new rear bumper design as well as new digital daytime running lights at the front and digital OLED lights at the rear.

The unique forged alloy wheels are another design change, but also bring a functional element. Measuring 23 inches they do a good job of filling out the wheel arches and give the RS Q8 Performance a purposeful stance and good proportions. But they are also 5kg lighter per wheel than the 22-inch rims on the RS Q8, saving unsprung weight to help the ride and handling.

Inside, Audi hasn’t made any dramatic changes to the design, which is fine because the brand does some of the best cabins on the market in terms of look and feel.

What is new is an aluminium inlay and an optional RS interior design package which provides a unique finish to the seats, with contrasting stitching, for an additional $4100.

So, what's changed with the facelift? Not much, meaning that the Mach-E – unveiled all the way back in late 2019 is beginning to look dated. Maybe that’s another classic Mustang trait.

The base Select gains the upper-series’ trick LED headlights. The Premium adopts some plastic body cladding. The grille treatments vary between the grades, with the GT boasting a unique look. Genuinely fresh new colours abound. And the alloys have been restyled.

Otherwise, it's still the same, Porsche Macan-esque small to medium-sized SUV crossover on the outside, down to the Hyundai Tucson-like vertical tail-light motif that barely seems like the regular Mustang muscle car’s, despite Ford’s intentions.

Inside, changes are largely limited to a repositioning of the gear selector from a rotary dial to a column shifter, Mercedes-style. That big portrait touchscreen could be straight out of a Ranger ute.

While it’s easy to get swept up in the power and speed of the RS Q8 Performance, it’s important to remember that it’s an SUV and it needs to offer ‘utility’ as well as ‘sports’. 

With that in mind, the front seat occupants are well looked after with supportive and comfortable sports seats, with a good amount of small item storage spaces. 

The rear seats are surprisingly comfortable, despite the sloping roofline of this ‘coupe-style’ SUV. Audi has cut recesses into the ceiling to create more headroom, so it will be fine for anyone under six-foot tall. Despite there being five seat belts, this is realistically more of a four-seater for adults, although three smaller kids could squeeze across the back.

There’s also a pair of cupholders, two USB-C ports, a 12-volt outlet and your own climate controls for the rear passengers.

As for the boot, again it loses some volume because it’s not a wagon-style SUV, but there’s still a decent, square floor space with a claimed 605 litres of capacity.

So, overall the Q8 obviously isn’t the most practical version of an SUV, but it does well given its focus on style.

As we’ve said before, the Mach-E is closer to something like, say, a BMW X4 than the boxier X3 from a proportions perspective, making it a classic coupe SUV.

Once you get over using the endlessly-annoying push-button door release, in lieu of a handle (why redesign the wheel?), that’s particularly noticeable entering/egressing the rear seat for larger people, though the front is fine.

While the interior is also clearly from an earlier era (and embarrassingly reminiscent of a Tesla), at least Ford finished engineering it for easy, seamless use.

The front seats are really comfy, ahead of a super-clear instrument pod, helping make for a great driving position, while the 15.5-inch display in the centre with Ford’s friendly SYNC4A operating system is simple to navigate once time is taken to familiarise. Current Ranger and Everest owners will feel right at home. The audio sound is superb too.

There’s a thoughtful amount of storage options, including for devices that require access to the handy USB outlets, ventilation is ample and the fit and finish in these Mexican-made Mustangs appears to be first class.

A big thumbs up, too, for the new column shifter and integrated central volume knob in the touchscreen that also allows adjustment of the climate control.

On the other hand, eyes must leave the road to dig into sub menus to change driving modes, side and rear vision is tight (those standard surround-view cameras sure come in handy), there are no paddle shifters to control regenerative braking, the glass roof neither opens nor completely blocks out sunlight due to there being no shade screen, and the overall ambience is more Ranger XLT than Ford LTD.

The back seat is surprisingly spacious given the coupe SUV dimensions, though the roofline may ruffle a few loose wigs. The backrests and cushions provides decent support, and most expected amenities are present, including air vents, USB outlets, overhead lighting/grab handles, coat hooks, cup/small bottle holders and centre armrest. And that glass ceiling does shower the cabin with light on a cloudy day.

Further back, the Mach-E offers 402 litres of cargo capacity that balloons out to 1420L with the split-fold back seats dropped, and there’s some hidden storage under the floor for smaller items. As mentioned earlier, the spare wheel is AWOL.

Existing owners will also notice a noticeably smaller ‘frunk’ area under the bonnet, where storage has plummeted from 134L to just 49L. That’s due to the newly-fitted heat pump that, at least helps boost efficiency in what is a spacious and practical family SUV.

Here's a worrying fact. The Mustang Mach-E is the cheapest new Ford passenger car you can buy in Australia that isn't based on a diesel-powered ute. And it still ain’t cheap!

When launched in Australia back in mid-2023, prices started north of $80,000 – all prices are before on-road costs – and then were swiftly slashed twice since then, as buyers basically stayed away.

Today, the well-equipped Select Single Motor RWD kicks off from $65,990. A grand more than before, but it does gain a heat pump to boost efficiency (though WLTP range remains steady at 470km), while also scoring more muscle, faster charging and – at last – softer suspension.

This is no stripped-back edition, with adaptive cruise control, dual-zone climate control, a 15.5-inch touchscreen, 360-degree-view camera, a glass roof, wireless Apple CarPlay/Android Auto, 10-speaker premium audio, a wireless charger, synthetic leather upholstery, powered and heated front seats, a powered tailgate and 19-inch alloys. Note that there is no spare wheel. Just a tyre-repair kit.

Meanwhile, the Premium Extended Range jumps $500 from $80,490 and continues with a bigger battery with an unchanged 600km of range, while it’s a near-$20K stretch from there for the flagship GT from $98,490.

Justifying a $1100-plus price hike is a more-powerful dual-motor set-up as well as a five-per cent range improvement at 515km, while retaining all-wheel drive (AWD), adaptive dampers, bolstered sports seats, 20-inch alloys and more.

Every grade includes advanced driver-assist systems (ADAS) tech from automatic braking and lane-support systems to 10 airbags ­– except in the GT, which only has nine. More on that in the safety section later on.

Against the stunning Polestar 4, swanky Kia EV6 and timeless Hyundai Ioniq 5, the Mach-E’s pricing is ballpark competitive, but is largely undercut by the sporty Cupra Tavascan, Skoda Enyaq, VW ID.4 and ID.5 cousins from Europe, as well as ubiquitous Tesla Model Y from China.

Speaking of which, the Ford seems downright unaffordable compared to the striking BYD Sealion 7, Deepal S07, Zeekr 7X, XPeng G6 and IM6 by MG. Game over then, you might think.

But, with names that sound like Cold War missile codes, none of these cheaper Chinese alternatives can match the rock-and-roll attitude that the evocative Mustang connection does.

And, damn it, the Mach-E’s calculated emotional play only heightens with exposure, which partly explains why it’s one of America’s best-selling EVs. Love it or hate it, even the comically contrived styling works.

This is the latest iteration of Audi’s twin-turbo 4.0-litre V8 petrol engine - and it’s a beauty.

While this engine is used in a variety of models, for the RS Q8 Performance Audi has taken power to 471kW with 850Nm of torque, which, as mentioned earlier, makes it the most powerful internal combustion engine Audi has ever offered in a production car.

That’s also a big boost over the previous RS Q8, which managed 441kW/800Nm, and is only just shy of the 485kW/850Nm offered by its ‘cousin’, the Porsche Cayenne Turbo GT.

Audi claims that the RS Q8 Performance will launch 0-100km/h in just 3.6 seconds and keep going to an electronically limited top speed of 250km/h. We tried to test the acceleration time on a closed circuit, but driving into a very strong headwind the big SUV could manage only 4.4 seconds - which is still a very quick time given its size and luxury.

The engine is paired to an eight-speed automatic transmission and Audi’s trademark quattro all-wheel-drive system to help smoothly transmit so much power to the road.

Though employing Ford’s Global Electrified One (GE1) platform that is a variation of the tragically discontinued Focus small car and Escape mid-sized SUV’s modular C2 platform, the Mach-E is basically a rear-motor, rear-wheel-drive EV, with the main traction unit now an in-house design. Previously that was outsourced.

A permanent magnet synchronous electric motor, it delivers 212kW of power and 525Nm of torque to the rear wheels via a single-speed reduction gear transmission.

Tipping the scales at 2086kg in the (albeit bigger-battery) Premium and 2100kg in the Select, its power-to-weight ratio is nearly 102kW per tonne and 101kW/tonne respectively. The latter needs 6.2s to streak from 0-100km/h, which is just 0.1s shy of the former. Top speed for both is 180km/h.

Meanwhile, with an electric motor added on to the front axle, the 2276kg, 434kW/955Nm GT’s 190kW/tonne slices acceleration down to just 3.8s, on the way to 200km/h, and relies on AWD, adaptive dampers and performance tyres to help keep things under control. Suspension consists of MacPherson struts up front and a multi-link rear end arrangement.

Unfortunately you don’t get the most powerful production engine without some trade-off, and for the RS Q8 Performance that means significant fuel consumption. The official fuel economy rating is a very thirsty 12.2L/100km, but that's the best-case scenario too. If you partake in some spirited driving that unleashes the full potential of the engine will result in a higher rate of premium unleaded being consumed by the big V8. We saw returns in the high teens across our time, but that was largely open road driving, so we’ll reserve final judgement for an extended test drive across more varied conditions.

Thankfully there’s a fairly large 85L fuel tank, so if you can hit the claimed average you can get a theoretical 696km of range.

Ford says the Select averages 18.5kWh/100km on the European cycle, while the Premium and GT are at 17.7kWh/100km and 21.0kWh/100km, respectively. These figures are in line with most rivals given the Mach-E’s performance capabilities.

Two distinct battery packs are offered, depending on grade.

The Select features a (useable) 73kWh Lithium Ferro phosphate (LFP) battery, for 470km of WLTP driving range. Premium and GT models switch to an 88kWh and 91kWh Nickel Manganese Cobalt (NMC) unit, bumping range up to 600km and 515km respectively.

The GE1’s 400V architecture has a CCS Type 2 port with 11kW AC charging capacity, or 150kW for DC charging. Many rivals offer faster charging capabilities.

According to the European data, AC charging from empty to full using a regular household socket needs up to 47 hours, or 10 hours with a 7kW Wallbox, while, a 50kW DC charger requires up to 90 minutes for a 10-80 per cent top-up, or under 40 minutes with a 150kW DC charger.

Obviously the RS Q8 Performance is all about speed, Audi made its intention clear by sending it to the Nurburgring to set a new SUV lap record for an SUV. But the reality is most owners are unlikely to hit the racetrack in the RS Q8, so what’s it like on the road?

In a word? Impressive.

While the engine is undoubtedly the star attraction offering up so much effortless performance, the RS Q8 Performance wouldn’t be so quick around the Nurburgring or as nice to drive on the road without its highly advanced chassis systems.

It has an array of technology to help it handle, it has active air suspension, adaptive dampers, active roll stabilisation and all-wheel steering, which help to make this big SUV handle like a much smaller car.

The suspension does a remarkable job of providing a compliant ride on such large alloy wheels, while also providing responsiveness.

The handling is certainly helped by the all-wheel steering, which gets the rear wheels to turn in the opposite direction to the fronts at low speed (below 50km/h), but in the same direction at high speed (above 80km/h), making the big SUV feels much more direct when changing direction.

As for the overall experience, that’s helped by Audi’s surprising decision to actually remove some of the sound insulation, which allows you to hear the engine even more than you ordinarily would. This really plays to the dynamic nature of the RS Q8 Performance.

If your idea of a Mustang is a big, heavy and rousing grand touring machine, then the Mach-E certainly lives up to the image.

And, in some ways, exceeds it, because – among the electric SUV fraternity – this one’s the driver’s choice, with a level of control and finesse that the muscle machines of yesteryear could only dream about.

Let's start with the performance. The 212kW Select and Premium are certainly fast enough. Sprightly off the mark, their acceleration is very smooth yet very determined, packing plenty of instantaneous punch when some extra squirt is required. Really, this is all the speed you’ll ever need.

Ford’s dynamic DNA force is very strong in these EVs, with steering that feels light yet precise, and naturally connected to the road, providing comparatively agile, flowing handling and decent body control. This is backed up by nicely nuanced traction intervention that – in true rear-drive Pony car tradition – allows for some playful rear-end breakaway.

After years of testing dreary, remote EVs – especially from but not just limited to China, the Mach-E’s willingness to interact with the driver is like enjoying a long, cold drink after hours in the hot sun.

With twin electric motors making 434kW and nearly 1000Nm, the GT turns the amp – if not quite the volume – up to 11, with tremendous response and terrific thrust right from the get-go. It’s actually quite astounding how contained and controlled the AWD flagship’s performance is delivered, given how brazenly fast it is down a straight road.

Jumping out of one of the other Mach-E models, the GT’s extra heft is immediately obvious around the bends, since it doesn’t quite have their lightness of touch. Grip is phenomenal, yet the driver can break traction even momentarily if desired, and there’s a sense that, in the right hands, few rivals with similar performance could keep up with the Ford in full flight. It’s fast everywhere all the time. But it’s just not quite as athletic or fun as the Select and Premium.

Note that, since we were on busy public roads, most of this assessment was carried out using the normal and not sport driving mode.

The driver assist safety systems are also really well tuned, sparing the driver the distraction and frustration of needless intervention, even when piloted enthusiastically.

The previous Mach-E was widely criticised for delivering a hard ride, even with the GT’s adaptive dampers. While you’d never call the suspension supple, the 2026 model’s ability to better absorb bumps is a welcome development, allowing the driver to better enjoy all the other benefits on offer. There are softer and more isolated alternatives, but few rivals are as rewarding dynamically.

Downsides include too much road noise intrusion over certain surfaces, the lack of paddles for the regenerative braking, and the fact that to switch that on or off requires the driver to resort to diving into a touchscreen menu. The same goes for switching between the cringy Whisper (eco), Active (normal) and Untame (sport) modes. How difficult would it be to fit a simple button to activate these?

Finally, thick pillars and small side/rear windows can make vision out difficult in tight spaces.

The Mach-E may be getting on to its sixth year in production, but there’s a welcome, non-EV analogue connection to the way this otherwise electrifying SUV goes, steers, handles and grips the road. Like many of the best Fords, the engineers have gone to the very real effort of prioritising driver enjoyment, without sacrificing everyday functionality.

Like we said earlier, the more time you spend in the Mach-E, the more enjoyable it gets.

Tested by ANCAP back in 2021, the Mach-E Select and Premium models managed a five-star ANCAP crash-test rating. The GT version remains unrated.

There’s a fairly comprehensive list of ADAS tech, including autonomous emergency braking (AEB) with intersection assist, reverse brake-assist, post-impact braking, lane-keep aid, lane-departure warning, evasive-steer assist, blind-spot monitoring, cross-traffic alert, adaptive cruise control with full stop/go functionality, traffic-sign recognition and tyre pressure monitors.

Select and Premium have 10 airbags (dual front, front-centre, a driver’s knee, front-side, rear-side and full-length curtain/head), but the GT misses out on the others’ front-centre airbag due its space-impeding bolstered sports seats, dropping the airbag count to nine.

The AEB tech operates between 5km/h to 80km/h in pedestrian, cyclist and back-over scenarios day or night, and between 5-187km/h car-to-car. The lane support systems work between 65km/h to 187km/h.

A pair of ISOFIX latches are fitted to the outboard rear seats, along with a three top-tether anchorage points.

Speaking of kids, while unnecessarily fiddly, the hidden door ‘buttons’ do have an anti-snag function that stops an opening door from slamming shut on venerable fingers.

Despite the extra power and fancy new brakes, the RS Q8 Performance costs the same to service as the existing RS Q8.

That means $4690 for Audi’s five-year service plan, and $5720 for the Audi Advantage.

The latter package includes an extra two-year, unlimited kilometre warranty on top of Audi’s five year/unlimited km coverage. It also includes two extra services and two more years of roadside assistance, to keep you covered for seven years total.

That’s good, but it’s still an extra cost when many mainstream brands already offer seven years of coverage as standard.

A five-year/unlimited kilometre warranty applies to the Mach-E, along with seven years of roadside assistance, activated annually if serviced at a Ford dealer.

Service intervals are every 12 months or 15,000km, whichever occurs first.

Prices for the 2026 facelift weren’t available at the time of publishing, but last year’s model alternated between costing $140 and $185 per service for the first 10 years. And the Mach-E can be maintained at any one of the 180-or-so Ford dealers network Australia-wide.

Ford says the EV Traction Battery is covered by an eight-year/160,000km warranty.
