Audi S6 vs Jaguar XF

What's the difference?

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.

With that iron fist wrapped in a velvet glove wrapped in bubble wrap engine, excellent ride and gorgeous looks, the XF Sportbrake ticks all the boxes. Apart from the entry price and options prices, there are few objective reasons not to buy the car. It's just as good as any of its German competition and arguably the prettiest of the lot.

Should Jaguar have taken the dive? Given the XF Sportbrake is a luxury wagon done right, yes.

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 second-generation XF is a very pretty car. A few carmakers have a had a crack at that four-door coupe idea, but Jaguar's Ian Callum got it right first go. You might expect the wagon to be a bit dumpy but it's far from it. That's not to say wagons can't be good looking - many are better-looking than the car they're based on (the weirdly proportioned Golf wagon being the exception to the rule). The XF sedan just looks right.

Anyway, the Sportbrake is basically the same until behind the B-pillar, with the roof continuing on to steeply raked tailgate glass. Obviously the lights are different back there but it's a nicely integrated job, it doesn't look like a dodgy extension. Rolling on the optional 20-inch wheels it looks amazing - low, long and well-proportioned. Unfortunately, it's more than vaguely hearse-like in black (the only First Edition colour).

Inside is standard XF, with the obvious exception of the rear seats and the big open load area. With this First Edition's glass roof the cabin seems infinite. Either way it's big and comfortable, although fit and finish could be a bit tighter.

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 and rear passengers enjoy plenty of space. Storage includes a not-quite-big-enough-for-a-phone tray ahead of the rotary dial gear selector and a pair of cupholders. Those in the rear have plenty of space, except for the middle seat occupant who must straddle a stout transmission tunnel. The rear armrest holds a pair of cupholders and the doors have slim pockets.

The boot holds 565 litres with the seats in place and "up to" 1700 litres with the seats down - that latter figure does not feel like a VDA number.

Over the years the XF has edged its way upmarket and is now playing with the Germans in the big luxury segment. And as is now customary for Jaguar, the Sportbrake is available in First Edition guise. First Editions are available for a model's first year of production and are usually based on the top-spec (in the Sportbrake's case, that's the 30d S) with a few extra bits and pieces to make things interesting.

While the 30d S retails for $123,450, the FE weighs in at $137,300. For that you'll waft out of the showroom with 19-inch alloys, dual-zone climate control, a huge panoramic glass roof with gesture-activated roof blind, around-view camera, front and rear parking sensors, 11-speaker Meridian-branded stereo with DAB, sat nav, head-up display, electric gesture-activated tailgate, keyless entry and start, rear air suspension, auto LED headlights, auto wipers, leather trim and a space-saver spare.

Jaguar Land Rover's 'InControl' media system is presented on a whopping 12.3-inch screen and, as ever, is steadily improving but goes without Apple CarPlay and Android Auto. The sound is, as you might expect, pretty good.

Our car had a few options fitted. 'Active Safety Pack' (see below), carbon-fibre trim ($3470), driver and passenger memory pack ($3210, including perforated leather trim), 20-inch wheels upgrade ($2790), cold-climate pack ($2540), illuminated metal treadplates ($2110), privacy glass ($950), 'InControl Protect' ($630), configurable interior lighting ($540), nets and rails ($390 and $320 respectively), extra power socket ($240) and 'InControl Apps' ($100). Most of it is cosmetic and/or unnecessary and took us to $158,950.

And there is still a plethora of boxes to tick.

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 First Edition ships with Jaguar's 3.0-litre twin-turbo diesel V6. Good for 221kW and a prodigious 700Nm, power heads to the rear wheels via an eight-speed ZF automatic.

With all that power and torque, the XF Sportbrake cracks 100km/h from rest in 6.6 seconds.

The air suspension means you can tow up to 2000kg with a braked trailer.

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.

Jaguar claims a combined-cycle figure of 5.9L/100km. Our time with it was mostly shuttling around the suburbs with a couple of highway runs and we managed a respectable 8.3L/100km.

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.

There's no getting away from the size and heft of the Sportbrake. Where a four-cylinder sedan comes in under 1600kg - not bad for an almost five-metre-long car - up here at the top it's well over 1800kg. With big wheels and a long wheelbase it's not going to win any wards for manoeuvrability, with a big turning circle and a length that's challenging to shopping centre car parks.

The 3.0 V6 twin-turbo is a fantastic unit. It can be a bit noisy when cold but it's super smooth and with all that torque it crushes overtaking with little need for advanced planning. The Sportbrake wafts along, lazily turning over in traffic and keeping the vibe calm.

Despite those big wheels, the ride is excellent. Even when in Sport mode, it's a rare bump or surface that will cause drama. It's very comfortable and very quiet, almost to the level of the XJ limo.

If you do fancy a bit of amusement, the V6 and well-sorted chassis are ready to play. In reality, Sport mode is where both myself and my wife left the car the whole time we had it. Both of us found the steering a little too light and preferred the more lively throttle response. The XF features torque vectoring using the brakes and coupled with a well-judged stability and traction control system, it delivers a good impression of a sporty sedan.

But the XF is best when you keep it relaxed. Both in town and in the cruise, it's a lovely, quiet place to be and a relaxing, undemanding drive. 

Only a couple of things were annoying - the light steering we've already covered. The heated windscreen was more reflection-prone so the head-up display could be hard to see in some lighting conditions. And sometimes it beeped for no apparent reason, which I eventually traced to the blind-spot warning.

The XF comes with six airbags, ABS, stability and traction controls, forward AEB, reversing camera, lane-departure warning, and tyre-pressure monitoring.

For child seats you've a choice of three top-tether anchors or two ISOFIX points.

Our car had the $4360 Active Safety Pack, which adds blind-spot monitoring, reverse cross traffic alert, lane-keep assist, adaptive cruise and driver-attention detection. If you were to ask me, this little lot should be standard at this level.

Despite that, the XF scored a maximum five ANCAP stars following assessment in 2015.

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.

Jaguars are offered with a three-year/100,000km warranty with a matching roadside-assist package. You can purchase a five-year/130,000km service plan for an oddly reasonable $2200. Even more reasonable are the service intervals - 12 months or 26,000km (!).
