Ford Mustang vs Audi S3

What's the difference?

Having driven the latest example of the Mustang GT, I hope Bill Ford is true to his word and keeps the V8-powered Mustang for as long as possible. It isn’t the most razor-sharp sports car or the most powerful muscle car, but it offers the kind of driving thrills and enjoyment that have made the car an icon.

The price increase is steep but the new technology inside drags the Mustang into the modern era and will add more youth appeal to a car that is largely unchanged in concept for the past 60 years.

But now that I’ve driven it in the USA and France, I can’t wait for it to finally reach Australia.

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

The updated Audi S3 Sportback is a fun-sized dynamo with impressive outputs and athletic road manners. It’s missing a few premium features, but its compact size paired with a gutsy engine makes it a compelling option for drivers who don’t want to compromise on performance (just space).

While this is considered a ‘new generation’ Mustang, the reality is this is more of a major overhaul than a complete, blank sheet redesign. As such, there’s a lot of carry over to the design, but that’s not to say there aren’t some significant changes.

For example, it’s still clearly a Mustang in its silhouette, sharing that with the sixth-generation model it replaces, as well as the now-iconic 1960s Fastback models, but the details are noticeably different.

To try and create more differentiation between the GT and EcoBoost models, Ford has designed unique front ends for each. Both are characterised by a strong horizontal line across the front of the more angular grille that meets the new ‘tri-bar’ daytime running lights.

The EcoBoost has an upper grille similar in size to the out-going model, the GT is a much larger upper section which incorporates a pair of ‘nostrils’ as well as a bonnet vent - both of which are functional for cooling and aerodynamics.

Down the sides Ford has lowered the beltline and created a more defined rear fender ‘shoulder’ that helps create the impression of a wider car. 

At the rear the famous ‘tri-bar’ lights remain and there are unique diffusers for each model, with the EcoBoost running two exhaust tips and the GT getting quad pipes.

But it’s inside where the biggest design changes have happened. The retro-inspired cabin of the sixth-generation - which features shiny silver plastic toggle-like switches and round air-con vents - has been overhauled.

The iconic ‘double brow’ design to the dashboard, which dates back to the original 1964 Mustang, has been dropped and replaced with a pair of digital screens. There’s a 12.3-inch display for the digital instrument cluster and a 13.2-inch multimedia touchscreen.

This change is designed to appeal to a younger audience but also allows for greater customisation and variety of displays, with Ford developing six different instrument panel options depending on the setting the driver chooses.

The primary three are the 'Normal', 'Sport' and 'Track' modes, which have been inspired by the GT supercar and the Mustang Mach-E electric SUV, while there’s also a 'Calm' setting, providing only the necessary data, such as speed, in a simplified format.

The final two have been created to tailor to fans of the brand’s 1980s ‘Fox Body’ Mustang, with digital versions of its round analogue dials in both a ‘Day’ and ‘Night’ mode, with the former using white graphics and the latter getting retro green dials.

The S3 Sportback may be a small car, but its S design features, like the stylised blackout grille, matrix LED headlights, and 19-inch alloys with red brake calipers, give it a distinctly athletic and fun-loving vibe. It’s compact, but definitely not diminutive and carries serious road presence. It’s hot hatch meets fun-size.

Inside, the S3 looks fabulous. Integrated ambient lighting, a sharp dashboard treatment and a driver-focused cockpit all lend it a premium feel.

The front seats look properly sporty with their integrated headrests, and the quilted Nappa leather upholstery feels great, especially with the eye-catching red contrast stitching.

As for technology, it’s as high-end as you’d expect with a 10.1-inch touchscreen multimedia display and 12.3-inch digital instrument cluster taking centre stage.

The only drawback? No sunroof. Combined with the black headliner and compact cabin, it can feel a little gloomy at times. Still, it’s a cabin you’ll enjoy spending time in.

The sixth-generation Mustang copped a lot of criticism for its interior look and feel, and while it certainly wasn’t at European levels of quality it was more affordable than any European V8-powered coupe.

The introduction of the new digital displays certainly adds a more premium impression to the cabin when you get inside, but you can still see a lot of the previous generation in this model, in particular the doors and centre console.

It’s pretty practical, for a sports car, with a pair of cupholders and a lidded centre console box for small item storage. 

One noticeable issue with the screens is the control virtually everything to do with the multimedia, including the air-conditioning, so trying to make small temperature adjustments is more complicated than just pressing a physical button. 

Not surprisingly space feels very similar to the outgoing Mustang with supportive and comfortable seating up front that made long stretches behind the wheel feel easy, which is nice for a sports car.

As for the rear seats, they remain incredibly tight for space and are better for soft item storage rather than squeezing people into.

Despite the largely carried over body and interior, the boot is slightly smaller than the previous model, with the coupe measuring 376 litres compared to the 408 litres offered previously. 

Like most hatches, the front row enjoys the most space. While it’s cosy, it never feels cramped. The seats are firm yet comfortable, thanks to their adjustability and expandable under-thigh supports. Access is fairly easy with wide door apertures, though the low seating position might earn a few grunts, especially from taller folks.

Storage up front is well sorted, with a glove box, a small centre console, a dedicated phone cradle and a couple of cup and bottle holders. It’s about what you'd expect for a car this size, but it's enough to keep things tidy.

There are plenty of charging options, with two USB-C ports in each row and a wireless charging pad up front.

The multimedia system is intuitive and easy to use. The touchscreen is responsive, and wireless Apple CarPlay connected without fuss and stayed connected all week. Wireless Android Auto is available, too.

Built-in sat nav is clear, and I love the way directions pull through to the digital instrument panel. The Sonos sound system? Pretty darn good. My son and I had more than one mini-concert on the school run.

As for the rear row, it definitely reminds you this is a small car. At 168cm, I found it on the cramped side of cosy and my husband just laughed when I asked him to try it! The wheel arch also cuts into the door aperture, making access a little awkward. Best to think of it as occasional adult seating. But given the size, that’s no surprise.

Amenities in the back are decent with a couple of map pockets, cup and bottle holders, as well as a fold-down armrest, those USB ports and rear temperature control (but curiously, no fan control). The seats are comfortable enough, but space is limited. Realistically, it’s best suited for two passengers, not three.

Boot space is quite practical. The wide opening and manageable load lip height make it easy to slide items in and out. It offers 325L of space, less than its key rivals, but expands to 1145L with the rear seats folded flat. The handy 40/20/40 split also adds versatility. Under the boot floor, you’ll find a tyre repair kit.

The A3 Sportback comes in three trim levels, with the S3 technically sitting in the middle, just below the performance-focused RS 3. It's priced from $78,800, before on-road costs, and it shares the same platform and underpinnings as the Volkswagen Golf R. Surprisingly, our test vehicle isn’t significantly more expensive than its Golf R rival which comes in at $70,990 MSRP.

That makes it a more affordable option when compared to premium rivals like the BMW M135 xDrive which starts at $83,600 MSRP and the Mercedes-AMG A35 which comes in at $89,700 MSRP.

The update sees engine outputs improve with it gaining 17kW and 20Nm of torque, resulting in a total of 245kW and 420Nm.

Feature highlights include 19-inch alloy wheels, red brake calipers, electrically-adjustable and heated front seats (with expandable under-thigh support), rear privacy glass, quilted Nappa leather upholstery and 'S Sport' suspension with damper control which lowers the ride height lowered by 15mm.

The updated technology is well-rounded and now comes with wireless Apple CarPlay and Android Auto. There's also three-zone climate control, a 10.1-inch touchscreen multimedia display, a 12.3-inch digital instrument cluster, digital radio, four USB-C ports, a wireless charging pad, built-in satellite navigation and a 15-speaker Sonos 3D sound system.

Still, despite its premium hot hatch status, this grade skips a few luxury touches. Ventilated front seats, a heated steering wheel, heated rear outboard seats and a sunroof are all missing. The BMW M135 xDrive, notably, includes all of these as standard.

Even the powered tailgate with kick-functionality is an optional extra here, adding $660 to the price. At this level that should be standard.

During the top secret development of this seventh-generation model there were plenty of rumours that Ford was considering a hybrid system for this Mustang. Fortunately for lovers of old-school V8 engines that proved not to be the case.

Instead it’s powered by a 5.0-litre V8 that's an evolution of the ‘Coyote’ unit from the previous ‘Stang but now featuring some technical changes, including dual throttle-bodies and separate airboxes to help improve performance. In the GT it’s tuned to make 345kW and 550Nm.

It can be paired with either a six-speed manual gearbox or 10-speed automatic transmission, both sending all the power to the road via the rear wheels.

The S3 Sportback wears the quattro badge proudly, meaning it’s all-wheel drive and it pairs a tweaked seven-speed automatic transmission with a 2.0-litre turbocharged, four-cylinder petrol engine.

This update brings a bump in performance over the previous model, including the addition of a rear torque splitter. Power is now up to a gutsy 245kW and 420Nm of torque, launching the S3 from 0 - 100km/h in just 4.7 seconds. That’s proper hot hatch territory.

While it hasn’t been confirmed by Ford, the Federal Government's Green Vehicle Guide has the Mustang GT rated at 12.8L/100km. And while that’s quite a thirst for unleaded petrol, it shouldn’t come as a surprise given it’s a 345kW 5.0-litre V8 engine.

If you value efficiency in your American muscle car, the four-cylinder turbocharged EcoBoost is rated at 9.4L/100km. But based on previous evidence, Mustang buyers are likely to opt for power over saving petrol.

The claimed consumption figure translates to a driving range between fills of around 650km.

The S3 Sportback has an official combined fuel consumption figure of 7.9L/100km and a 55-litre fuel tank, giving it a theoretical driving range of up to 696km.

Its key rivals hover around similar numbers, so it's right on the mark for the segment. After a mix of long-distance drives and my usual urban errands, my real-world figure came in at 8.0L/100km - very close to the claim, which I’m pretty happy with.

As promised earlier, here’s how the Mustang GT felt powering through the French countryside…

But first, it’s worth acknowledging that, in truth, it wasn't hard work getting through the traffic even in the manual Mustang. While the clutch is on the heavier side, it’s got a smooth action and the engine's torque and flexibility make darting in and out of gaps in the traffic a breeze.

However,  once out on the open roads the Mustang really could run free. The V8 engine sounded fantastic bellowing out across the fields and through the quaint little villages we passed through.

As you'd expect, the V8 provides plenty of grunt, it's an incredibly flexible engine pulling hard right across the rev range and makes us appreciate even more that this now remains the last of its kind since the demise of the V8-powered Chevrolet Camaro and Dodge Challenger.

Driving the Mustang in conditions like this makes you understand why it has been such a popular sports car not only in Australia but around the world for decades.

While the manual transmission has fallen out of favour with Aussie buyers, the truth is it's the pick for this GT. The fact it has less ratios to choose from than the 10-speed automatic means it feels more urgent and (again) the flexibility of the engine allows it to shine.

Not that the auto is bad, it does a fine job, it just lacks the buzz and engagement the manual ‘box provides.

What arguably impresses even more than the engine is the handling. Having driven the Dark Horse last year and being so impressed by its handling, particularly with the 'Performance Package', there was some concern prior to driving the GT that it would feel less impressive and, dare I say, duller.

But that's far from the case. Instead, the GT feels responsive and well sorted across a variety of road conditions. While it may lack the precise handling characteristics of a European sports car, it’s clear Ford has made this latest Mustang better suited for the rest of the world, not just America.

Not that Ford has made the Mustang too serious, as the introduction of the Drift Brake demonstrates. This rally-style electronic handbrake allows you to, as the name suggests, snap the car into a slide - when the circumstances allow.

Ford finally gave us our first (official) use of the Drift Brake when it paid us up with stunt driving expert, Paul Swift, who taught us how to slide the Mustang into a parallel park.

Obviously this is not designed for road use but for those who want to take their Mustang to the track it will no doubt lead to a lot of fun and some shredded tyres.

The S3 Sportback sounds as mean as it looks, and it delivers on that promise with effortless grunt. Acceleration is immediate, with plenty of power on tap when you need it. It’s just fun all around.

The lowered sports suspension and wide tyres do bring some extra noise into the cabin, even at lower speeds. You might find yourself repeating things to rear passengers now and then, but it never feels overwhelming.

Steering and suspension are on the firmer side, so yes, you’ll feel the bumps but the payoff is sharp, responsive handling. Quick lane changes and winding coastal roads are where this car shines.

Visibility is about what you’d expect from a low-slung hot hatch. The pillars don’t obstruct the view, but sitting beside a towering SUV at the lights can make you feel a bit... compact.

Cornering is a strong suit, thanks to the car’s wide stance and AWD system. It feels confidently planted in most conditions. That said, I noticed the occasional wobble through the rear frame on rough sections in heavy rain.

Its compact size makes parking a breeze, especially with the help of multiple sensors. The reversing camera is crisp, but at this price point, the lack of a 360-degree camera view feels like a missed opportunity.

The S3 isn’t covered by its 2WD sibling's maximum five-star ANCAP safety rating but it is well-equipped with safety features all the same.

Safety equipment includes blind-spot monitoring, side exit assist, rear cross-traffic alert, lane departure alert, lane keeping aid, park assist, reversing camera, front/rear parking sensors, forward collision warning, autonomous emergency braking and adaptive cruise control with stop and go function. 

It also has six airbags but misses out on a front centre airbag. None of the driver assist systems are intrusive to daily driving, which I always like.

The rear row has ISOFIX child seat mounts and three top-tether anchor points but only two child seats will fit.

There are no details confirmed at this stage but there’s no reason to believe the Mustang won’t be covered by Ford Australia’s usual five-year/unlimited kilometre warranty.

Similarly, service intervals are likely to be 12 months/15,000km.

For reference, capped price servicing on the out-going Mustang GT came in at $299 for each of the first four services, up to four years/60,000km. Not bad.

Audi backs the S3 Sportback with a five-year/unlimited kilometre warranty, which is on par with its European rivals. A five-year pre-paid servicing plan is available for $2890 which is cheaper than pay-as-you-go and reasonable for the class.

For those looking to go the extra mile, the 'Audi Advantage' package lets you extend the warranty and capped-price servicing by an additional two years, which represents solid value overall.

Servicing intervals are every 12 months or 15,000km, whichever comes first.
