Ford Mustang vs Audi S3

What's the difference?

Obviously we can't speak to the whole of this new, seventh-generation Mustang range having only experienced the Dark Horse. But that's enough to make you appreciate just what a special car the Mustang is, even after all these years.

The company has managed to find new ways to improve arguably its most iconic model, keeping it fresh for a new generation. The Dark Horse is a worthy addition to the line-up, for however long it lasts, bringing a higher level of dynamic capability that will appeal to both long-time muscle car lovers and anyone who appreciates a good sports car.

The truth is, this is no mid-life crisis for the Mustang, it's actually ageing very gracefully, taking on new dimensions as it does. The bigger question is how much longer it has left in it, at least with an internal combustion engine. But that's a question for another day, for now we should just eagerly anticipate its arrival in Australia in 2024.

There are plenty of historical instances where a particular model within a broader range manages to hit the absolute sweet spot even though it’s not the fastest or most expensive variant. Porsche’s GTS specification across various models is a great example of this.

And at the risk of being proven wrong when the all-new RS3 comes along later this year, this car, the S3, might just pull off that feat.

Yes, the new RS3 will be more powerful and will offer even more grip and sporty flavour, but it will also be more expensive. And we defy anybody to drive the S3 and say that it lacks dynamism in any single area.

It’s also a magnificently balanced car with the right amount of attention paid to every aspect of its trim and performance. That, in essence, is where that `balanced’ label originates and even though it’s felt most in the actual driving experience, it permeates throughout the entire vehicle.

Ford figured out with the fifth-generation model that what customers want is a Mustang that retains the silhouette of the original 1960s Fastback, so ever since the design has been evolutionary rather than radically different.

That's no different with this seventh-generation model, which features a more modern look, with crisper lines, but still is unmistakably a Mustang from every angle.

There have been some more significant design changes though, the most obvious one being the decision to have a clear visual difference between the V8-powered GT and four-cylinder EcoBoost at the front-end of the car.

So, the GT gets a larger, more aggressive front grille and a vented bonnet, whereas the EcoBoost has a more subtle appearance, but both have a clear family resemblance.

The Dark Horse elevates this edgier look even further, with a more aggressive appearance that includes a racier bodykit, with a sizeable rear wing, that speaks to its more serious intentions.

The Dark Horse also includes a first for the Mustang in seven generations - a forward facing horse badge. While the now iconic striding 'Stang profile badge remains for the GT and EcoBoost, the Dark Horse gets its own unique badge that shows Ford isn't afraid to try new things even after all these years to keep the car fresh.

The forward facing view is meant to signify a dark horse in a race, sneaking up from the rear to take victory, with its flared nostrils meant to connect to the dual throttle bodies of the Mustang Dark Horse.

Perhaps the most striking thing about the styling of the new Audi is just how similar it looks to the old model. Okay, this is not a new thing with Audi which has made a point of not throwing a handsome design into the dumpster in pursuit of new for new’s sake.

As such, the exterior lines are taut and typically Audi clean and, with the latest LED headlights and a refinement of the Audi trapezoidal grille, the look is fresh and crisp without being a novelty act.

Inside, the virtual dash display and large, relatively flat centre console almost amount to anti-styling. Or it would if the rest of the deal wasn’t so sharply angled towards a philosophy of less is more.

Again, this is classic modern-era Audi where the game is to make a complex layout look as simple as possible. The face-level air vents also seem to have borrowed a little Lamborghini (part of the Audi family) DNA.

I particularly like the new shift-by-wire gear selector which is a nifty looking switch but works just as intuitively as a conventional shift lever. New tech meets old muscle memory, I’m calling it.

It's worth mentioning (again) just how good Audi’s customisable dashboard display is. With sharp, clear graphics and the ability for the driver to prioritise the information on display at the time, the S3’s display is still about the best in the business.

Overall, ergonomics have always been a long-suit of this brand and there’s been a clear intention to follow that tradition this time around.

The interior of this latest Mustang sums up where Ford was at with this new-generation model, as it introduces some attention-grabbing technology but also carries over large amounts of the previous model's design.

For example, the interior doors look nearly identical to the old model, with the same handles, window buttons and even trim elements.

The layout of the centre console is largely the same, too, with a pair of cupholders and a lidded centre console box making up the bulk of the small item store space.

The materials used have improved in some areas and stayed the same in others, with the softer touch plastics introduced on the mid-life facelift of the sixth-gen used again here.

However, the Dark Horse also gets a new carbon-fibre effect trim that features prominently around the dashboard for a fresh and sportier look.

But far and away the biggest difference between the old model and this new one is the instrument panel. Gone is the iconic 'double brow' design and in its place is a huge digital display that combines two screens into one long, plank-like element.

It's a 12.4-inch digital instrument panel and a 13.2-inch media touchscreen integrated together to try and help the Mustang appeal to a younger, more tech-savvy audience that wants its car to integrate with a digital lifestyle.

Unquestionably it makes a statement, whether you like the statement it's making will depend on your point-of-view.

If you love technology and the personalisation it offers you'll love it, but if you pine for the days of analogue dials you'll likely think it looks too much like a giant smartphone.

What you can't deny is the capability it brings, with a variety of virtual instrument displays to suit each of the driving modes the car has, including 'Normal', 'Sport' and 'Track', as well as the fun 'Fox Body' layout that harkens back to the '80s Mustang.

The central media screen has also been utilised for the Dark Horse with extra auxiliary gauges - for g-force, oil temperature, oil pressure, etc - able to be displayed, as well as the 'Track Apps' feature that allows you to record lap times, start times and controls the launch control and drift brake settings.

Unfortunately, the screens also control virtually everything, including the air-conditioning, so trying to make small temperature adjustments is more complicated than just pressing a physical button.

As for the seating, the Dark Horse is available with two seating choices up front in the US (and likely in Australia), with a standard six-way power adjustable leather sports seat or an optional Recaro racing-style seat trimmed in suede and mircofibre.

As for the rear seats, they remain incredibly tight for space and are better for storing bags rather than carrying people without severely compromising front seat leg room.

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.

The Dark Horse we drove in the US was fitted with a tyre repair kit under the boot floor.

While SUV owners are often quick to tell you that they bought their car for its interior space, the truth is sometimes different. And without the huge wheel-wells and suspension towers of a high-riding SUV, the conventional hatch or sedan often has an advantage.

Certainly, there’s no lack of room in the S3 and the hatchback version has a wide hatch opening to make loading easier. The sedan, however, is a full 150mm longer than the hatch and that extra is all behind the rear seat.

So the boot is actually very useable with a capacity of 325 litres. Audi claims the same 325 litres for the Sportback, but that figure jumps to 1145 litres with the rear seat folded flat.

The rear seat in either variant is handily split 40/20/40 and there are storage nets on the back of each front seat, luggage nets in the cargo area and 12-volt outlets in both the centre-rear and luggage compartment. Even floor mats are standard.

There’s only one trim level across the S3 range, so it doesn’t matter whether you choose the sedan or hatch, the level of standard kit remains the same. And extensive.

As with many performance variants of a platform, what you’re paying for in the S3 is the hardware that allows it to be a more aggressive, more involving drive. So, compared with the A3, the S3 gets much more engine performance, bigger brakes and improved suspension.

Inside, the S3 runs to S-specific trim and presentation (instrument display, steering wheel) standard heated, powered, four-way lumbar-adjustable sports seats, a black headliner and the 15-speaker Bang & Olufsen stereo that’s a $1500 option on some variants of the A3.

The interior is also home to a 10.1-inch info screen, dual-zone climate-control, an auto-dimming mirror, keyless entry and push-button start, wireless phone charging, rain-sensing wipers, park-assistance and acts as a Wi-Fi hotspot. Connectivity runs to Android Auto, Apple CarPlay and sat-nav.

Helping the image match the performance, the S3 also gets dark aluminium accents, alloy pedals, ambient lighting and gloss-red brake calipers to give it the visual punch the price-tag suggests.

Speaking of price, the new S3 represents a fair hike over the outgoing S3, and a sticker of $70,700 for the Sportback and $73,200 for the sedan means the new model will be tickling the $80,000-mark as a drive-away proposition.

Compared with the old model, those prices represent a leap of around $6000, not to mention a spike of around $23,000 or $24,000 over the entry-level versions of the new A3 on which it’s based.

But perhaps a more meaningful comparison is with the 40 TFSI variants of the new A3 which also feature Audi’s famous Quattro all-wheel drive system.

In that case, the price difference between the A3 and S3 is closer to $17,000; closer, but still a big tweak to the monthly lease repayment.

Given you’re starting with a premium-priced product to begin with in the A3, the extra performance and dynamics offered up by the S3 seems to be reasonably priced given the scope of their influence.

Again, you need to see it through the prism of high-end motoring, but when you do, you can see where the money has gone.

And if you have even more to outlay, there’s always the 'Premium Plus' package for the S3. That gets you a panoramic glass sunroof, head-up instrument display, 360-degree cameras, a memory function for the driver’s seat (which should be standard at this end of the market) and a memory function for the exterior mirrors. Yours for an extra $3990, which, given some makers charge that just for the sunroof, seems a pretty reasonably proposition.

Despite plenty of rumours that Ford was preparing to electrify the Mustang, either as a hybrid or full battery EV, in the end the company has stuck to the tried and tested formula.

That means an updated version of the 5.0-litre V8 and a 2.3-litre turbocharged four-cylinder 'EcoBoost' engine, similar to the one offered in the previous generation.

The range-topping Dark Horse features the most powerful naturally aspirated engine Ford has ever installed in a Mustang, making 372kW (which is 500-horsepower) and 566Nm.

However, Australian models may not quite hit that figure due to our older emissions regulations, but a final number hasn't been released by Ford Australia.

The 5.0-litre V8 is paired to either a six-speed manual or 10-speed automatic transmission and a Torsen limited-slip differential.

The manual gearbox is specific to the Dark Horse, the Tremec unit is the same one used in the Mach 1 and features the same ability to 'flat shift' - change up gears without lifting off the accelerator if you have full throttle applied.

The GT features a slightly different version of that same 5.0-litre V8, and as mentioned earlier, it's available with or without an active-valve performance exhaust.

Australian GTs will get the improved exhaust system, meaning it will make 362kW/566Nm; instead of 358kW/562Nm with standard exhaust. It too is available with a 10-speed auto or a six-speed manual Getrag gearbox.

Finally, the EcoBoost engine is an all-new version of the same engine featured in the last model, featuring the same capacity and format but upgraded performance. The 2.3-litre four-cylinder unit makes 235kW/474Nm, up from 224kW/441Nm the previous engine produced.

Here’s where a lot of the extra currency demanded for the S3 goes. Forget the 1.5-litre engine in the base-model A3, and instead move to the two-litre four-cylinder as seen in the A4 40 TFSI. Then, add extra turbo-boost (up to 1.8 bar thanks to an efficient intercooler) different variable valve timing protocols, and a direct fuel-injection system with a specific calibration and the potential to create injector pressures of up to 350 bar, and you have the S3’s powerplant.

Maximum power is 228kW at anywhere from 5450 to 6500rpm, and maximum torque of 400Nm produced in a broad range between 2000 and 5450rpm.

Transmission is a seven-speed dual-clutch unit driving through all four wheels as per Audi’s Quattro mantra, although it’s important to note this version of Quattro is the simpler, arguably less pure, on-demand system where the car behaves as a front-drive platform until the all-wheel-drive system is required to step in.

That said, with 228kW under its wheels, that’s a fair bit of the time. And compared with previous systems, this one takes more notice of driver inputs and wheel-speed to be less reactive and more active.

As final specifications haven't been locked in for the Australian market we're basing these numbers off the US Environmental Protection Agency's claims.

They have the trio of Mustangs rated at 13.8L/100km for the Dark Horse and GT with their manual gearboxes, the GT auto at 13.0L/100km and the EcoBoost at 9.0L/100km to make it the most efficient of the bunch - unsurprisingly.

Audi quotes an official combined cycle fuel consumption figure of 7.4L/100km for the A3 Sportback and 7.3 litres for the sedan.

That difference is a bit of a mystery given the sedan is heavier (by just five kilograms) until you consider that the combined figure includes freeway running, at which point the sedan’s extra 150mm of length and different rear diffuser may be the aerodynamic deal-breaker.

The Sportback emits 170 grams of CO2 per kilometre (166 for the sedan) and with the 55-litre tank fitted, both variants should have a range of around 750km between fill-ups.

While the final Australian specifications may not be locked in just yet, Ford did provide us with a comprehensive drive experience in the Mustang Dark Horse.

We spent three days with this new model, driving it across a variety of conditions including urban roads, highway stretches, winding country roads and even at the Charlotte Motor Speedway.

Across all conditions the Dark Horse demonstrated a more refined driving experience than the model it replaces. The sixth-generation was the first Mustang designed for the global market, rather than focusing on the USA, and that meant it couldn't quite match its more worldly rivals.

But Ford has clearly worked to make strides on that front, including adding the Dark Horse to the Mustang range to launch with a definitive flagship model.

The engine may be carried over rather than all-new but you won't care when you put your foot down. The roar from the V8 is truly a thing of beauty to anyone who appreciates an evocative exhaust note.

It's a deep, guttural growl at low revs and builds to a more high-pitched scream as it approaches its 7300rpm redline.

It packs a punch, too, with enough grunt to shove you back in your seat and had no trouble hitting 205km/h just halfway down the back straight at the Charlotte Motor Speedway circuit.

It's a joy to drive with the six-speed Tremec 'box, especially on the track as it has both the rev matching for downshifts and the flat shifting for upshifts, which make you feel like a racing pro.

The flat shifting does take some getting used to and requires a lot of faith the first time you try it, as you need to have more than 90 per cent throttle and more than 5000rpm to make the system work correctly and not crunch the cogs. But when you get it right it just feels so good.

Even without that, on the road it's a nice gearbox to use, with a short, mechanical throw. It may feel a bit heavy for some, but it's in keeping with the muscular attitude of the Mustang.

It also feels really well matched to the engine, on the track but also the road. The engine has enough torque to take-off in second (and probably third) gear, feels nicely spaced through the middle gears and will cruise along in sixth gear in a relaxed manner.

The automatic is a nice alternative if you really don't want a manual, but the 10 speeds feel like overkill at times.

It has a preference for looking for the tallest gear possible at any stage in order to save fuel. This included on the racetrack, where it felt like it still wanted to go to the highest gear it could if you left it to its own devices.

Using the steering wheel-mounted paddle shifters is the better choice when you want to go for a spirited drive, but it just doesn't feel as engaging or shift as crisply as the manual.

As for the handling, on the road the Dark Horse is a pleasure to drive, with a new level of poise and directness than even the Mach 1 possessed. The steering is excellent, with a directness to it that makes the Mustang feel responsive to your inputs.

It helps that the Dark Horse rides on Pirelli tyres developed specifically for it, which provide excellent grip on the road and add to that feeling of responsiveness and composure.

However, if you want to take that to the next level, then you'll need to speak to Herrod Performance about adding the Handling Package options.

However, it's not clear at this stage if that will include the amazing Pirelli P Zero Trofeo RS tyres that are used in the USA. At this stage they're not approved for use in Australia, which is a shame because they provide immense grip and, once again, elevate the Dark Horse above any Mustang we've had so far.

The changes to the aerodynamics and suspension, along with the tyres, combine to make the Mustang Dark Horse with the Handling Package a genuine rival to the likes of the BMW M4 and Audi RS5 Coupe, in this reviewer's opinion. We'll stop short of saying it's clearly better, but it's definitely a rival on performance terms.

The other notable new addition to this generation Mustang in a nod to the younger audience is the addition of the 'drift brake' that allows you to slide the back of the car around.

Working like a rally car handbrake, the drift brake only needs you to dip the clutch and pull up on the lever/bar and the back wheels lock up and allow you to slide. It's a fun new addition that does add a new dimension to a car that was previously focused on straight line performance at the drag strip.

Some cars take a few minutes at the wheel before they start to get chatty. Not so the S3. From the moment you grab the lovely leather tiller, haul it into gear and give the perky little turbo-motor a squeeze on the throttle, the Audi is making all the right noises and giving clear, precise feedback on its every move.

Sometimes, cars with lots of tyre, lots of all-wheel drive grip and the sort of sharp steering fitted here, can start to feed back so many responses that it becomes difficult to know which one to respond to.

Not the S3, which seems tuned to a keener driver’s priorities (as it should be, of course). As a result, the steering feedback is distinct from what the rest of the front end is doing and everything else going on is clear, quantifiable and designed to improve the experience.

That even extends to the soundtrack which, Audi told us does not use any electronics to improve it beyond amplifying the engine-bay harmonics which use the windscreen and scuttle as their 'speaker.'

Combined with the active exhaust system, this car honestly sounds like a five-cylinder engine (I opened the bonnet to count the spark plugs to make sure it wasn’t. It isn’t.)

If you’ve ever driven a five-cylinder Audi or a V10-powered R8 (two in-line fives, really) the tune will be a familiar one. Lovely, and – again - such amazing attention to detail.

The 2.0-litre engine runs fairly high boost levels, but that doesn’t seem to have affected the way it storms off the mark. Neither does the dual-clutch transmission contribute any delay, provided you haven’t managed to stand on the brake and throttle at the same time (as many left-foot brakers might).

At that point, the driveline goes into sulk mode and will force you to wait a heartbeat or two before full power is restored. This can be an issue when trying to dart across a busy intersection or merge into a traffic flow.

It’s not a new thing to Audis, but remains an annoyance to those of us who equate having two pedals with having two feet.

The driver-selectable drive modes fitted to the S3 are interesting inasmuch as they actually make a meaningful difference to the way the car operates. They alter the transmission shift points, the throttle sensitivity, steering weight and damper settings.

'Comfort' mode will be the default for most owners, and while 'Dynamic' does sharpen up the dampers ever-so-slightly beyond an acceptable day-to-day level of firmness, it also adds weight to the steering feedback.

Frankly, I don’t think it needs it and simply adding resistance feels like a token gesture. And since the steering has a (non-negotiable) variable rate in the first place, bigger inputs equal a bigger proportionate change of direction anyway.

The damping control is now the more sophisticated magnetic-hydraulic type where hydraulic pressure varies the valving rather than the simpler, previous system of energising an electro-magnet to alter the viscosity of the damping fluid.

This more finite control system has allowed more 'bandwidth' as Audi puts it, between Comfort and Dynamic damper settings.

While the auto mode is almost prescient, it’s not actually pre-emptive but rather takes into account suspension deflection, wheel-speed and driver inputs to come up with a combination of settings to make the most of the situation.

And if you really want to fiddle, you can choose 'Individual' and create an overall setting that combines bits of Comfort and Dynamic with a smattering of 'Efficiency' thrown in.

Toggle down to Dynamic and throw the S3 at some bends and it soon emerges as a pretty gripped-up piece of equipment. The front-drive bias is not really noticeable, but then neither is the transition where the computer begins to engage the rear multi-plate clutch to turn the rear axle into an active participant.

There’s certainly no lack of grip at any stage of a typical corner, and even the odd unexpected damp patch poses no awkward questions. Perhaps the biggest grumble would be the tyre roar at highway speeds, but that’s often the price of performance rubber.

No surprises for guessing that Audi has this angle absolutely covered.

Some driver-assistance technologies have now filtered down from larger more expensive Audi models, and are standard fitment on the S3. Those include collision-avoidance assistance, lane-departure warning, rear cross-traffic assistance and parking assistance programs.

There’s also adaptive cruise-control, hands-on detection, traffic-jam assist, exit warning, a rear-view camera and a tyre-pressure monitoring system.

You also get the usual six air-bags including side-front bags and curtain air-bags at head height for rear-seat passengers. The S3 also gets a centre-front air-bag; a move that is likely to become a lot more widespread in the not-too-distant future and is designed to avoid head clashes between the front-seat passengers in a side impact.

Autonomous emergency braking is fitted and can also detect pedestrians and cyclists; a first for the S3.

The S3 scored a maximum five stars for safety in ANCAP testing.

Again, this is one of those topics with limited confirmed details 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.

Audi has finally had to cave in and extend its warranty to match its competition. So, any new Audi sold after January 1 this year moves up to a five-year/unlimited kilometre factory warranty; a big step up from the previous three years of cover.

S3 buyers can also opt for Audi’s five-year service plan which costs $2580. Servicing is set down for every 15,000km or 12 months.
