Maserati's Quattroporte is part of a dying breed. A decade or so ago, the European manufacturers took a huge amount of pride in their range-topping big luxury sedans, cars you can either drive or be driven in, bristling with the latest technology.
While by no means low-tech, the Maserati Quattroporte takes the high style route, focussing on a luxurious interior with that handmade feel.
|Engine Type||3.0L turbo|
|Fuel Type||Premium Unleaded Petrol|
Most buyers don’t care for sedans these days, but those in the premium market are still spoilt for choice, with new model after new model being launched.
The latest on offer is the new Audi S6, which once again attempts to mix executive style with boy-racer performance.
With its predecessor’s 4.0-litre twin-turbo V8 succeeded by an engine that is 1.1 litres and two cylinders short, does it still serve up enough bang for your back?
Of course, the only way to find out is to put the new S6 sedan to test, so that’s exactly what we did. Read on.

Beauty is way more than skin-deep in the Quattroporte and while the 330 doesn't have the punch of the S, it's hardly that much slower. Maserati reasons you will want to spend the $25,000 saved on options, concentrating on the Italian craftsmanship rather than the outright performance available in the V8 or the efficiency of the less aurally attractive diesel.
As with any car of this type, you've got to want one in the first place, but for a big, beautiful sedan, there's nothing as good looking this side of an Aston Rapide. The Quattroporte 330 does nothing to dim the allure of Modena's big mover and, if you're that way inclined, nobody on the outside will ever know.
For Quattroporte money would you stick with the Italian or be tempted by one of its German rivals? Let us know in the comments below.
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.
Long, flowing lines mark out the Maserati as something quite different to its German, British and Japanese competition. This Quattroporte has increased in every dimension but the lines cover its size beautifully.
Big wheels, long wheelbase, low ride but it still looks like a sedan rather than pretending to be a coupe.
The elegance of the lines is complemented by a distinct lack of bling – there's little in the way of chrome work or shouty details. There's plenty satin finishes available and the beautiful paint, while available in pretty much any colour you like, is best kept to a restrained, deep hue. Or silver.
The cabin will doubtless age well. Classic shapes house a fairly conventional but hugely comfortable cabin. The front seats have heaps of adjustment and are large but supportive. Naturally, the leather is soft and supple.
The central screen isn't the dominant feature, like a 50-inch LCD screen in a small living room while buttons are kept to a minimum.
The rear seat is sensationally comfortable, with hectares of available space and a seat comfortable for either lounging or working.
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.
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.
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.
Price and features
The 330BHP uses the same, Ferrari-built V6 but detuned to 'just' 330 bhp. The price has been detuned too, dropping $25,000 from the V6 S's entry price to kick off at $210,000.
Maserati 330bhp benefits from an overall specification improvement across the range, landing in your garage with a ten-speaker stereo with USB and Bluetooth, power everything, dual-zone climate control, keyless entry and start, front and rear parking sensors with reversing camera, cruise control, sat-nav, auto headlights and wipers, double glazed windows and an interior covered in leather and wood.
Later in the year, your Quattroporte will be available with a new silk trim from Zegna
Only very occasionally does it become clear that Maserati is part of the Fiat Group and that moment comes when you use the 7.0-inch central screen in the dash.
The software is based on the group's UConnect and it isn't great. It's not bad, but it feels its age (however, it's much better than the system on the Gran Turismo), needing a lot more work or a quick surrender to Apple's CarPlay or Android Auto.
Once you work your way through the weird menus, it's fine to use and is miles ahead of the not-much-cheaper Lexus LS unit which is almost unusable.
Sound from the ten speaker stereo is crystal clear and the phone performance is also very good.
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.
Engine & trans
Like the S, the 330bhp is powered by Maserati's twin turbo 3.0 litre V6, made with more than a dash of Ferrari involvement. As the name suggests, it produces 243kW and a chunky 500Nm. With just under two tonnes to shift, the ubiquitous eight-speed ZF automatic transmission whisks the Quattroporte 100km/h in 5.6 seconds, only half a second down on the 301kW V6 S.
Maserati claims 9.1L/100km on the combined cycle (with the help of stop-start), which seems reasonable given our figure of 10.8L/100km, which we got a with a mix of city and highway running as well as a very enthusiastic blast through some secret back roads.
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 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.
Just a few hundred metres behind the wheel is all it will take to convince you the Maserati belongs in the same class as the competition. It's incredibly quiet – courtesy of the acoustic double glazing – and all occupants benefit from supreme comfort.
While the 330 is 58kW down on the full fat V6, you won't really miss them. There's a fat torque curve, with all 500Nm available from 1750 to 5000rpm, meaning easy progress for the 5.2 metre sedan.
The Quattroporte has two sport buttons to choose from – one looks after the drivetrain and exhaust valving while the second stiffens up the Skyhook suspension.
With the first sport button pressed, you get a more lively throttle, sharper shifts and a glorious noise from the exhausts, although they are a long way from your ears.
It's still a fast car, with strong acceleration from standstill and in the gears, the power as linear as you like with no real turbo lag and a most un-turbo noise to go with the performance.
The only dynamic problem is the electric steering – it seems to get confused between your inputs and feedback from the road, the tyres feeling like they're 'nibbling' an uneven surface, tweaking the wheel in your hands.
The assistance is a little spotty, too, unexpectedly changing weight. It's just a bit weird. In normal driving, you'll never notice it.
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.
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.
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.
