Audi S6 VS Maserati Ghibli
- Executive style
- Improved value
- Boy-racer performance
- Not SUV practical
- A touch thirsty
- Substandard warranty
- Okay warranty
- Marginal on value
- Fast but not furious
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.
|Engine Type||2.9L turbo|
|Fuel Type||Hybrid with Premium Unleaded|
So, there’s two hundred grand burning a hole in your pocket, and you’re keen to extinguish the flames by purchasing a premium, full-size, high-performance sedan.
Both can tear the tarmac off the road thanks to outputs in the ‘getting on for 600 horsepower’ range, and dynamic systems finely honed by unhinged boffins in Munich and Affalterbach.
But what if you prefer to follow a less-predictable path? One that sends you due south to Modena in Northern Italy, the home of Maserati.
This is the Maserati Ghibli, specifically the new S version, offering more power and torque than the standard issue.
It’s the famous Italian brand’s take on a serious sports sedan. But the elephant-sized question in the room is, why choose the road less travelled? What does this Maserati have that BMW or Merc’s finest doesn’t?
|Engine Type||3.0L turbo|
|Fuel Type||Premium Unleaded Petrol|
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.
Maserati will tell you people are drawn to its motor-racing heritage and sporting DNA, and that the Ghibli offers something different in a world of grey, business-like conformity.
There’s no doubt the M5 and E63 are left-lane autobahn hot rods, stunningly fast but relatively remote. The Ghibli S delivers a more nuanced driving experience. And the design details all through the car actually do connect with the brand’s history.
So, before you go Deutsche you might want to think about a high-emotion Italian relationship.
Does the Maserati Ghibli S GranSport's dynamic character put it at the top of your premium performance sedan wish list? Tell us what you think in the comments below.
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.
For 2018, the Ghibli is available in two new trim levels. Add $20k to the ‘standard’ price tag and you can choose between the GranLusso, with a focus on luxury (including the option of a Zegna silk interior treatment!), or the more performance-focused GranSport you see here, the high-output S version, resplendent in ‘Blu Emozione’.
The GranSport is identified by its unique front and rear bumpers, as well as a chrome concave grille, with two wings and a prominent splitter underneath it.
More recent Maserati design signatures, including three stylised vents in the front guards, and aggressively angular (adaptive LED) headlights, merge with classic references like delicately formed trident badges on each C-pillar to form a distinctively dynamic exterior. It’s aerodynamically slick, too, boasting a low 0.29 drag coefficient (down from 0.31 for the 2017 car).
Then you open the door and step inside. In this case, the bright-blue exterior is matched with a black and red interior. Make that mostly red, in fact mostly very red leather on the seats, dash and doors, with trademark touches like the oval-shaped, dash-mounted analogue clock, hooded instrument binnacle, and racy alloy-finish pedals setting the tone.
Taking a different path to its Teutonic competition, the Ghibli S dash and centre console combination manages to blend gentle curves with an occasional sharp turn. Cover over the trident badge and other brand giveaways inside, and it doesn’t feel like the usual suspects. It‘s a distinctive, characterful design.
Also worth calling out is the fact that when you crack the bonnet open to impress your friends they’ll actually be able to see the engine, or at least major parts of it. Like alloy cam covers, complete with Maserati in old-school cursive script in the casting. Yes, there’s some plastic dressing on top, but the ability to lay your eyes on real metal warms the heart.
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.
Front-seat passengers enjoy a spacious feel, thanks largely to the dashboard’s progressive slope towards the windscreen, rather than the hard-edged, upright layout more commonly found in high-end sedans.
There are two cupholders in the centre console, but locating anything bigger than a piccolo latte in them would be a struggle. Same goes for the doors. Yes, there are storage bins, but forget water bottles or anything much thicker than an iPad (in a Gucci slipcase of course).
That said, there are several covered storage boxes in the centre console, as well as multiple connection options including an ‘auxiliary in’ socket, USB port, SD card reader and 12v outlet, plus a specific drawer for your mobile (in place of a now-deleted DVD player).
No surprise then that rear space is generous. I was able to sit behind the driver’s seat, set for my 183cm height, with plenty of legroom and more than adequate headroom. The gap for your feet under the seat in front is kinda squeezy, but it’s nowhere near a deal-breaking issue. Three large adults across the rear is do-able, but tight.
There are two adjustable vents for rear-seaters, map pockets on the seat backs, small door bins, plus a neatly configured storage box and (small) twin cupholder combination in the folding centre armrest.
The rear seat backs split-fold 60/40 to increase the standard 500-litre cargo capacity and improve load flexibility. There’s a 12v outlet, a side net pocket, and decent lighting back there, too. But don’t bother looking for a spare, a repair kit is standard issue, and an 18-inch space saver is an option.
Price and features
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.
Cost of entry to this exclusive Italian club is $175,990 (plus on-road costs) for the Ghibli S, with an additional $20,000 opening up the choice of Ghibli S GranLusso or S GranSport ($195,990).
No small chunk of change, and in the same territory as the M5 and E 63, so what does that mean in terms of standard spec and tech?
For a start, the S GranSport rolls on 21-inch ‘Titano’ alloy rims, and features an eight-speaker, 280-watt Harman/Kardon sound system (including DAB digital radio). You’ll also luxuriate in extended leather trim (including a leather-wrapped sports steering wheel), carbon and piano black interior highlights, 12-way power-adjustable and heated front seats, keyless entry and start, sat-nav, LED headlights, power rear window sunshades, power boot lid (with hands-free mode) and soft-close doors.
There’s also dual-zone climate control air, cruise control, front and rear parking sensors, a rear-view camera (plus surround view), rain-sensing wipers, a sunroof, ambient lighting, alloy-finish pedals, a 7.0-inch TFT instrument display, and an 8.4-inch colour multimedia touchscreen with Apple CarPlay and Android Auto present and accounted for.
That’s plenty of luscious fruit, which is cost-of-entry in this rarefied market territory.
Engine & trans
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 Ghibli S is powered by 3.0-litre, 60-degree, twin-turbo V6 petrol engine, designed by Maserati Powertrain in Modena and manufactured by Ferrari, just up the road in Maranello.
It’s an all-alloy unit featuring direct-injection, variable cam timing (inlet and exhaust), low-inertia parallel turbos, and a pair of intercoolers.
While it can’t match the powerhouse Germans on outright numbers the Ghibli S still produces just over 321kW, or around 430 horsepower at 5500rpm, and 580Nm of torque from 2250-4000rpm. That’s a boost of 20kW/30Nm over the outgoing Ghibli S.
Drive goes to the rear wheels via a ZF-sourced eight-speed automatic transmission.
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.
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.
So, the first thing to say is the Ghibli S GranSport is fast, but it’s not in the same eye-widening league as the M5 and E63. The sprint from 0-100km/h is covered in 4.9 seconds, and if you’re game (and your driveway is long enough) claimed maximum velocity is 286km/h. For reference, the just released (F90) M5 is claimed to hit triple digits in 3.4sec, and the E 63 in 3.5.
The V6 turbo sounds nice and growly in the Sport setting, the soundtrack controlled by pneumatic valves in each bank of the exhaust. In ‘Normal’ mode, the bypass valves are closed up to 3000rpm for a more civilised tone and volume.
Maximum torque is available across a useful band from 2250 to 4000rpm and the twin-turbo set-up helps with linear power delivery, while the eight-speed auto is quick and positive, especially in manual mode.
The sports seats (12-way electric adjustable) feel great, a 50/50 front to rear weight distribution helps the car feel balanced, and the standard LSD helps put power to the ground without fuss in tight going.
And despite a 1810kg kerb weight, it does, in fact, manage to feel lighter and more involving than its high-profile, highly powerful German rivals.
Braking is courtesy of big (red) Brembo six piston calipers at the front, and four piston at the rear on vented and cross-drilled rotors (360mm front/345mm rear). They’re up to the task, and the claimed 100-0km/h stopping distance is impressive at 36m.
The new electrically assisted power steering (a first for Maserati) is light at parking speeds, but it points nicely and road feel improves as the speedo needle twists to the right.
Suspension is double-wishbone front, five bar multi-link rear, and despite big 21-inch rims wrapped in high-performance Pirelli P Zero rubber (245/35 front-285/30 rear), ride comfort is amazingly good, even on patchy surfaces.
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.
Maserati’s ‘ADAS’ (Advanced Driver Assistance Package) is standard on the Ghibli S, and now includes lane-keeping assist, blind-spot monitoring, and traffic-sign recognition.
There’s also AEB, forward-collision warning, ‘Advanced Brake Assist’, ‘Rear Cross Path’ and a tyre-pressure-monitoring system.
The 2018 Ghibli and larger Quattroporte sedan are also the first Maseratis to feature IVC (Integrated Vehicle Control), a tailored version of ESP (Electronic Stability Program), using a smart controller to predict driving situations, adapting engine speed and torque vectoring (by braking) in response.
The ‘Maserati Stability Program’ (MSP) also wraps up ABS (with EBD), ASR, engine brake torque control, ‘Advanced Brake Assist’ and a hill holder.
In terms of passive safety the Ghibli is equipped with seven airbags (front head, front side, driver’s knee, and full length curtain) as well as anti-whiplash headrests.
There are three top tether points across the rear for child seats, with ISOFIX anchors in the two outer positions.
Although ANCAP hasn’t assessed the Ghibli it rates a maximum five stars from EuroNCAP.
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.
Maserati supports the Ghibli S GranSport with a three year/unlimited km warranty, which is now some way off the industry leading eight years (160,000km) from Tesla, and seven years (unlimited km) from Kia.
But the recommended service interval is a lengthy two years/20,000km, and the ‘Maserati Maintenance’ program offers pre-paid schedules for Ghibli and Quattroporte owners, covering required inspections, components and consumables.
