Audi S6 vs Mahindra XUV500

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.

This petrol-powered and well-priced XUV500 W6 might mark Mahindra's most convincing effort at cracking Australia's congested SUV market, but we're still not completely convinced.

That said, it's certainly cheap, the ownership credentials stack up and it's a very comfortable way to transport seven people.

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.

There's no getting away from the fact the XUV500 is not the sleekest, prettiest SUV in the pack. But it's not ugly, either. More that it looks like it's doing its best with a design philosophy hatched a generation or two ago.

Its best angle by far is when viewed straight on, where the piano-black grille, dual bonnet bulges and complicated (read: a little weird) headlight clusters all add some road presence to Mahindra's only SUV.

A side-on viewing, however, is less satisfying, where a combination of strangely placed and super-sharp body creases (including one over the rear wheelarch, which adds a Harbour Bridge-style crescent to the otherwise-straight window line) and serious rear overhang give the XUV500 an inescapable awkwardness.

Inside, expect a vast collection of rock-hard (though nicely patterned) plastics, with the ambiance rescued somewhat by the clean-looking and vertical central control unit, which is home to the media screen and air-con controls. 

Ready for some hashtag real talk? There are better-looking and better-feeling seven-seat SUVs out there. But there aren't many that start at $25,990 drive-away. And I think that's Mahindra's point.

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.

Pretty damn practical, actually, regardless of whether you want to carry people or cargo. Carrying both at the same time, however, is tricky.

But let's start with people. There is a huge amount of room in the third row of the XUV500, a space with enough head and legroom to put plenty of its competition to shame.

Thanks to second-row seat backs that fold flat, before the the entire seat lifts up and pushes forward, climbing into seats six and seven isn't too big a drama, either. 

We rarely say this about seven-seat cars, but at 175cm, I'd feel plenty comfortable back there on a longer drive. There are two air vents in the third row, too, along with bottle storage and side-seat storage for thin items.

All XUV500's are fitted with a 70-litre fuel tank. 

The space in the middle row is ample as well, and you'll find three ISOFIX attachment points, one for each of the three seats. There's also a door pocket in each rear door and storage nets on the rear of the two front seats. A pull-down divider that separates the back seat is home to two cupholders, matching the two for front seat riders. 

The only downside to all this people-lugging happiness is that, with the third row of seats in place, there is absolutely no room for luggage. Mahindra doesn't quote a litre storage figure when seven are seated (mostly because it would probably be embarrassing to write "one litre"), but trust us, you'll be lucky to squeeze a soft backpack in the boot with all seats in place.

Things improve considerably when you drop the third row of seats, though, which unlocks 702 litres of storage, and that number climbs to 1512 litres with the second and third row folded down.

Make no mistake, this Mahindra kills the competition on price. The entry-level W6 version will cost you a lean $25,990, while the fruited-up W8 version will set you back $29,990. You can even have an AWD W8 for $32,990. The best part? All of those are drive-away prices.

Go for the W6, and you can expect 17-inch alloy wheels, cloth seats, air-con with vents (powered by a second compressor) in the second and third row, cornering headlights with DRLs, front and rear fog lights, cruise control, rear parking sensors and a 6.0-inch multimedia screen linked with a six-speaker stereo.

Spring for the W8, and you'll add leather seats, a reversing camera, tyre-pressure monitoring and a bigger, 7.0-inch screen with standard sat-nav.

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.

There's a diesel engine currently available, but the clock is ticking - Mahindra expects it to be phased out within six months. But the big news here is the new petrol engine, a turbocharged 2.2-litre unit good for 103kW/320Nm. It's paired exclusively with an Aisin-developed six-speed automatic transmission, and will send it's power to the front or all four wheels.

Mahindra doesn't quote official performance figures, but those engine outputs hardly scream excitement, do they?

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.

Local numbers are yet to be confirmed, but after an admittedly vigorous local test, the on-board computers was reading 13+ litres per 100km. All XUV500's are fitted with a 70-litre fuel tank.  

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.

About as old school as rocking a pair of button-up tracksuit pants with a Run-DMC cassette stuffed into your Walkman.

On a straight and unchallenging road, there's stuff to like about the petrol-powered XUV500. The engine, while gruff under heavy acceleration, doesn't feel too wheezy when you're not asking a great deal of it, and nor is the cabin overly loud at suburban speeds. It's a comfortable space for driver and passengers, too, and the gearbox performed seamlessly on our short test drive.

But that's about where the good news ends. There's an unshakeable agricultural feel to the way this Mahindra SUV goes about its business, and nowhere is that more obvious than through the steering wheel, which has only a vague and difficult relationship with the the front tyres, making it seriously tricky to approach twisting roads with anything approaching confidence.

The steering is slow and cumbersome - light when you first begin turning the wheel, with a ton of weight appearing by surprise midway through the cornering process - and it has a tendency to fight back should the front wheels find a bump or corrugation in the road, too. 

The body lolls about when challenged, too, and the tyres are quick to give up their grip on tighter corners. All of which would give it a certain retro charm if it wasn't so very new, and I must admit I was cackling maniacally on some of the more twisting roads.

But it's simply not a car I could live with.

Expect dual front, front-side and curtain airbags (though the latter don't extend to the third row of seats), along with rear parking sensors and ESP. Stepping up to the W8 trim adds a reversing camera with dynamic guidelines. The XUV500 was awarded a four-star (out of five) ANCAP assessment when tested in 2012.

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.

All XUV500s are covered by a five year/100,000km warranty (though the final two years apply only to the drivetrain), along with five years of complimentary roadside assistance.

The XUV500 is also covered by Mahindra's capped-price servicing program for the first three years of ownership, and will require servicing every six months or 10,000km.
