Alfa Romeo Giulia vs Audi S6

What's the difference?

The Giulia is a love letter to the increasingly lost art of the sporty executive sedan. As refined as it is beautiful and oh-so elegant to drive, it’s a reminder of why we always love Alfa Romeo, even when the odds are against it.

Emotional cars like this are hard to come by and they will soon be gone, replaced by something new. The future is not necessarily worse, but it will be different, so if a sporty European sedan with a combustion engine is calling out to you don’t miss your opportunity to drive the Giulia while it still exists in this form.

We adore the new S6 sedan. It looks great, feels comfortable and goes like stink all at the same time. What’s not to like?

It also helps that it is relatively good value, safe and practical by large-sedan standards, so it’s a bit of a no-brainer.

But will buyers be quick to dismiss the new S6 sedan because it’s not a more practical SUV? Time will tell, but we hope not.

Does the new Audi S6 sedan represent the best mix of executive style and boy-racer performance? Tell us what you think in the comments below.

Like any good Alfa Romeo should be, the Giulia is a work of art. It’s sleek, sharp, and immaculately proportioned.

This most recent update has artfully refined a formula too good-looking to mess with. The increasingly dorky headlamps from the previous car have been swapped out for a more contemporary all-LED set, with a three-bar DRL pattern.

The grille has also been tweaked for this update for a more modern style, and the Veloce is now graced with the iconic and more aggressive sport two-tone alloy wheels in the traditional five-hole 'tele-dial' style.

It’s effortlessly attractive, and instantly recognisable as an Alfa on the road. I can’t think of a better way to stand out in today’s executive sedan landscape.

The interior has received less of an upgrade for the 2024 model year, with the same core parts. The major change is the old-school analogue instrument cluster being swapped out for a slick 12.3-inch digital unit.

The puzzling thing about this is the 8.8-inch central multimedia screen hasn’t been upgraded in-kind, making a strange contrast between the sharp and fast digital instruments, and the laggy and dull multimedia panel.

At least it effortlessly sits behind the curvaceous design of the dash as to not interrupt a good shape.

There are of course plenty of other touches which I love. The leather seats look and feel the part, as do the real metal paddle shifters which float behind the simple yet refined and sporty steering wheel.

The push-to-start button on the wheel is reminiscent of other Italian sports machines, while the tasteful smattering of leather, gloss plastic, and textured surfaces keep the premium feel on-track.

Some areas I’m not so keen about: Some of the interior plastics, particularly for buttons and toggles, feel cheaper than they should, and the door cards are oddly basic considering how much attention has been given to every other part of this car’s look and feel.

To these eyes, the new S6 sedan is very attractive, albeit not outlandish, in keeping with its executive focus.

Up front, the subtly aggressive S body kit immediately comes into frame, with the bumper sporting sinister-looking side air intakes.

And, of course, there’s Audi’s signature Singleframe, which is not only large and in charge, but also finished in gloss-black, like many of the S6 sedan’s exterior design elements.

Below the heavily creased bonnet, the HD Matrix LED headlights look both angry and sophisticated, with their integrated LED daytime running lights (DRLs) providing a crisp signature.

Around the side, the S6 sedan goes about its business quietly, but its blistered wheelarches do add some bulk and help to accentuate its strong shoulder line.

And then there are the thick skirts and 21-inch alloy wheels (with a space-saver spare), which have a sporty twin five-spoke design. It’s all very classy.

Speaking of which, the rear end is arguably the S6 sedan’s best angle thanks to its wicked LED tail-lights, which have a segmented signature.

The chunky bumper below incorporates a diffuser element that houses the quad exhaust tailpipes, while a blink-and-you’ll-miss-it bootlid spoiler rounds out the look.

Inside, the S6 sedan is a technological tour de force, with 10.1- and 8.6-inch touchscreens dominating its centre stack. The former is responsible for most of Audi’s latest multimedia system’s functions, while the latter takes care of the climate controls.

This set-up works pretty well, although a few too many taps are required for certain functions, and then there’s the issue of the glass display coverings, which are absolute fingerprint magnets alongside the gloss-black accents used throughout.

That said, the 12.3-inch digital instrument cluster and windshield-projected head-up display on hand are brilliant. In fact, they set the standard for the entire industry thanks to their design and breadth of functionality.

The S6 sedan does, of course, feel a little bit more special than the regular A6 inside, with the obvious additions being the front sports seats, which are covered in supple Valcona leather alongside the armrests. They even have diamond-stitched inserts.

Then there’s the obligatory flat-bottom steering wheel (with paddle-shifters), which is trimmed in Nappa leather alongside the gear selector, upper dashboard, door shoulders and knee rests. Indeed, hard plastics are hard to find here.

Meanwhile, a black headliner adds to the sportiness alongside the black Alcantara door inserts, but the cabin is otherwise a familiar (read: classy) affair.

The Giulia is an old-school low-slung sports sedan. Many will prefer the SUV sensibilities of the Stelvio, with its bigger hatch-opening boot, and its higher ride height can better accommodate less mobile passengers, and makes it easier to fit child seats and the like.

For those willing to trade those things away for a superior drive experience, the Giulia is still solid to live with every day, but has a few drawbacks.

For example, those strangely basic door cards offer only a tiny map pocket with a nook I’d hardly describe as a bottle holder.

The centre console offers two larger bottle holders with variable edges, but there’s also not much else in the way of storage in the cabin aside from a smaller-than-average glove box and armrest console box.

The big win for me is the physical dial set and shortcut buttons for all the key climate functions, making it easy to operate while you’re concentrating on driving.

At least the seats are well bolstered, and front passengers are treated to plenty of adjustability. Visibility is okay, and it was easy for me to find a comfortable driving position at 182cm tall.

The rear seat is a similar story. It’s tighter, and you have to duck down below the roofline to get into it.

Once inside, I was pleasantly surprised to find enough room for my knees and somewhere for my feet to slide behind my own driving position, although the centre position is all but useless thanks to an enormous raise for the driveshaft.

Headroom is passable, but you wouldn’t want to be much taller than me. 

There are, again, tiny bottle holders in the doors, and a further two in the drop-down armrest. Rear seat passengers get dual adjustable air vents on the back of the centre console, one USB 2.0 outlet, and elastic nets on the backs of the front seats.

The boot measures 480 litres which is up there with a lot of mid-size SUVs, but because it’s a sedan, access is more limited, and it won’t accommodate as many awkwardly-shaped objects.

Measuring 4954mm long, 1886mm wide and 1446mm tall, the new S6 sedan is a large sedan in every sense of the term, which is mostly good news when it comes to practicality.

Cargo capacity is decent, at 520L, but can be increased to an undisclosed amount with the 40/20/40 split-fold rear bench stowed.

Speaking of the boot, there are four tie-down points and a cargo net to help secure loose loads, while a bag hook and a side storage net are also on hand, alongside a 12V power outlet. Bulkier items will, however, be confronted by a decent load lip.

In-cabin storage options are numerous, but not all are effective. The glovebox is well-sized, while the driver-side cubby is surprisingly large, but the central bin is shallow, mostly taken up by the wireless smartphone charger, two USB-A ports and the SD and SIM card readers.

A pair of cupholders is located in the centre console, with a 12V power outlet found in between, while the front door bins can accommodate one regular bottle each, just like their rear counterparts.

In the second row, there’s a fold-down armrest with two more cupholders as well as a shallow storage tray, while cargo nets are affixed to the front seat backrests.

The rear bench is pretty comfortable, with four inches of legroom available behind my 184cm driving position alongside decent toe-room. Headroom is also good, with about two inches on offer.

That said, three adults sitting abreast won’t enjoy the experience, due to the large transmission tunnel, which makes for limited footwell space. At least they’ll have access to a couple of USB-A ports and a 12V power outlet, below the central air vents.

For reference, child seats can be fitted to the outboard seats via top-tether and ISOFIX anchorage points.

The new S6 large sedan is priced from $149,900 plus on-road costs and is far better value than before, even if it does command a $33,900 premium over the regular A6's flagship variant.

Compared to its predecessor, the new S6 sedan is $21,480 cheaper, while Audi Australia claims it has also added $20,000 worth of kit.

Standard equipment not already mentioned includes metallic paintwork (our test vehicle was finished in Tango Red), dusk-sensing lights, rain-sensing windshield wipers, soft-close doors, auto-folding side mirrors with heating, rear privacy glass and a hands-free power-operated bootlid.

Inside, satellite navigation with live traffic, Android Auto and wireless Apple CarPlay support, digital radio, a 705W Bang & Olufsen 3D sound system with 16 speakers, a panoramic sunroof, keyless entry and start, power-adjustable front seats with heating, a power-adjustable steering column, four-zone climate control, an auto-dimming rearview mirror and LED ambient lighting feature.

Of note, buyers can opt for the $7700 Dynamic Package that bundles in speed-sensitive electric power steering, a rear limited-slip differential and all-wheel steering. It was not fitted to our test vehicle.

In terms of rivals, the BMW M550i sedan is identically priced, while the Mercedes-AMG E53 sedan is much more expensive, at $173,800. The S6 sedan arguably has the former beat on value but loses the performance battle due to its 390kW/750Nm 4.4-litre twin-turbo V8.

The Veloce might not pack a Ferrari-derived six-cylinder engine like the Quadrofoglio, but its smaller 2.0-litre four-cylinder turbocharged petrol engine hardly wants for power.

Packing 206kW/400Nm it outpunches six cylinders of old easily, and is still capable of sprinting to 100km/h in a hot-hatch baiting 5.7 seconds to a Vmax of 240km/h.

It even sounds fantastic, as it flies up the rev-range living up to every bit of the Alfa promise. Peak power arrives at 5250rpm, but peak torque hits at 2250rpm.

Smooth shifts are provided courtesy of an eight-speed traditional torque converter automatic transmission.

The new S6 sedan is powered by a hard-hitting 2.9-litre twin-turbo V6 petrol engine that produces a strong 331kW of power from 5700-6700rpm and a punchy 600Nm of torque from 1900-5000rpm.

Compared to its aforementioned predecessor, power is unchanged, while torque has increased by 50Nm.

This unit is mated to a 48V mild-hybrid system that includes a trick Electric-Powered Compressor (EPC), which helps to reduce its turbo lag.

A reliable eight-speed torque-converter automatic transmission is responsible for swapping gears, while drive is sent to all four wheels via Audi’s rear-biased quattro system.

This combination helps it sprint from a standstill to 100km/h in an impressive 4.5 seconds, while its top speed is electronically limited to 250km/h.

The 2.0L turbocharged engine has an official combined cycle fuel consumption figure of just 6.1L/100km, although I saw 9.0L/100km in my time with it.

I’ll admit it was being enthusiastically driven, and treated to lots of urban commuting.

The Giulia has a 58-litre fuel tank and requires mid-shelf 95 RON premium unleaded fuel. Its approximate range on a full tank at the official consumption is 951km.

The new S6 sedan’s fuel consumption on the combined-cycle test (ADR 81/02) is 8.4 litres per 100 kilometres, while claimed carbon dioxide emissions are 197 grams per kilometre. Both figures are pretty keen given the level of performance on offer.

Audi says the aforementioned 48V mild-hybrid system reduces fuel consumption by 0.4L/100km thanks to its coasting ability, which sees the engine turn off for up to 40 seconds between 55km/h and 160km/h. It also engages idle-stop from 22km/h.

In our real-world testing, we averaged 14.4L/100km over 100km of driving skewed towards country roads over city traffic, with limited highway time. It’s worth noting that my spirited driving inflated this result. That said, while its fuel consumption is not as bad as it appears, this is still a thirsty sedan.

For reference, the S6 sedan’s 73L fuel tank takes 98RON petrol at minimum.

Put simply: The Giulia is a celebration of Alfa Romeo. Yes. Even with a humble 2.0-litre turbocharged engine and an automatic transmission, this is a deeply emotional car. A riveting experience from behind the wheel.

Fly round corners, your eyes wide, exclaiming ‘magnifico!’ as the Giulia gracefully leans in, the rear LSD, sporty tyres, and wonderfully tight steering working together in harmony as you eke out just a smidge of tyre roar.

Laugh out loud to yourself, as you plant the accelerator, hear the muted rumble of the surprisingly angry little engine, and feel the turbocharger kick in half a second later as you power out.

‘Eccezionale!’ You’ll think, as you feel the click of the immensely satisfying metal paddle-shifters, and the transmission responds in-kind, the engine roaring up the revolutions with enthusiasm.

Sure, the Veloce grade is not as raw, or as wild, or near as fast as the top-grade Quadrofoglio, but all of the exciting spirit of  that car is still here, and at a little over half the price, too. The Veloce is an absolute delight to drive.

It has such poise, makes such a fine sound, and does it all so gracefully. This is how you make a car feel as one with the driver.

Even the ride is deeply impressive. It’s not too harsh or noisy, while gifting the chassis just the right amount of lean in the corners and allowing enough play for it to remain controlled over bumps.

Not only does it work well when you’re driving as it's clearly intended to be driven, but around town it’s quiet and refined inside, living up to the promise of a luxury sedan.

The seats and bolstering are great, the visibility isn’t too bad, and while I’ll complain about the slightly laggy software on the multimedia screen, the digital dash is responsive and the physical climate controls are welcome.

It’s not all perfect. If it were, I think it might cease to be an Alfa Romeo and start sprouting BMW badges.

For example, our test car, with less than 2000km on the odometer, had various inconsistent rattles emanating from the plastic garnish around the digital dash, and somewhere behind the back seat.

Regardless, driving this car has made me a little sad Alfa will be putting this wonderful platform behind it in pursuit of more electrified goals.

I can only hope wherever the Giulia nameplate goes next, it retains the spirit of this version.

The S6 sedan has no right being this good in a straight line and around corners…

Much of its success is owed to the 2.9-litre twin-turbo V6, which is now one of my favourite engines being built today. Simply put, it absolutely hammers.

Punch the accelerator from a standing start and it doesn’t take long for 600Nm to be on tap all the way through, and just a little bit beyond, the mid-range.

Occupants are firmly pressed into their seats as the S6 sedan sprints towards the horizon with vigour. Soon enough, 331kW arrives and hangs around until just prior to the redline.

Needless to say, this acceleration is addictive, and the EPC deserves some of the credit, as it effectively mitigates any dreaded turbo lag and ensures the engine is always seemingly on boost.

But we also need to acknowledge the eight-speed torque-converter automatic, which is a real beauty. Gear changes are nice and smooth, which is great, but what’s even better is their relative quickness – dual-clutch transmissions be damned!

Of course, extra performance can be extracted by switching between the engine and transmissions’ settings but, rest assured, they both stand up, no matter what.

However, we’d suggest spending time in the former’s most aggressive setting, as it unleashes the sports exhaust system, which sounds unreal.

Upshift with intent and you’re met with a booming ‘brap’. Downshifts and the overrun will even gift you a series of pops. In fact, the S6 sedan soundtrack sounds strangely similar to that of the five-cylinder RS3, and we have absolutely no problem with that.

Better yet, the S6 sedan has an appetite for corners, with its neutral handling a standout, partly thanks to its hard-working rear-biased quattro all-wheel-drive system, which works in tandem with all the other electronics to ensure there is plenty of grip at any given time.

This controlled driving pleasure is enhanced by the electric power steering on hand, which has a variable ratio. At low speed, it’s nice and light, but those after more heft can always switch to another one of its settings, which become progressively heavier… arguably too heavy.

Feedback through the wheel is also good, while the steering itself is pretty direct, lending itself to sporty driving, which, of course, is half of the S6 sedan’s mantra.

Coming into corners, braking performance is solid, thanks to the massive 400mm front and 350mm rear discs with red callipers, so the driver is brimming with confidence at every turn, even though there’s an unladen weight (with 75kg driver and luggage) of 1985kg to manage.

But let’s not forget the S6 is an executive sedan, so it has to ride like one. Thankfully, it does. The independent five-link suspension has air springs and adaptive dampers, which serve up comfort in spades, especially at high speed.

Its firm tune does come into frame when travelling on unsealed or uneven roads, with this exacerbated by the large 21-inch alloy wheels, which have a penchant for catching sharp edges.

ANCAP awarded the A6 range (including S6) a maximum five-star safety rating in 2018.

Advanced driver-assist systems extend to autonomous emergency braking with pedestrian detection, lane-keep and steering assist, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control with stop-and-go functionality, high-beam assist, driver attention alert, hill-start assist, tyre pressure monitoring, surround-view cameras and front and rear parking sensors. Yep, buyers aren’t left wanting here.

Other standard safety equipment includes six airbags (dual front, side and curtain), electronic stability and traction control systems, anti-skid brakes (ABS), brake assist and electronic brake-force distribution, among others.

Alfa finally updated its warranty to a more industry-standard five-years and unlimited kilometres in 2022.

Service intervals occur at 12 monthly or 15,000km intervals for the 2.0-litre turbocharged variants. Pricing was not available for the model year 2024 version yet in the brand’s online calculator, but to give you an idea for the pre-facelift version, pricing came in between $345 and $1065 per visit, averaging $573 per year for the first five years of ownership. Not cheap, but not as expensive to run as you might expect.

One thing you might want to keep in mind is depreciation. Boring, I know, but even late model examples of the Giulia and Stelvio have been hit particularly hard by the depreciation stick according to residual values we searched up on Autotrader.

For reference, the Genesis G70 and BMW 3 Series have both fared much better in equivalent 2.0-litre turbo forms.

The S6 sedan comes with Audi Australia’s three-year/unlimited-kilometre warranty, which falls short of the premium market’s relatively new five-year standard that was set by Genesis and followed by Mercedes-Benz.

Three years of roadside assistance is also bundled in, although this term can be extended up to nine years if the vehicle is serviced at an authorised dealership, which is great.

Speaking of which, service intervals are every 12 months or 15,000km, whichever comes first. Capped-price servicing plans are available, costing $2350 for three years/45,000km or $4110 for five years/75,000km. They’re pricey, but you weren’t expecting the opposite.
