Volkswagen ID. Buzz vs Audi S6

What's the difference?

The only way to make this car cooler would be to add a split fold-out windscreen and a tube steel luggage rack on the roof.

It’s fast, super practical, comfortable and guaranteed to put a smile on the face of premium family buyers ready to go for something different. And that smile will extend to just about everyone who lays eyes on it. I love it.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

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.

The ID.Buzz GTX is characterised by a unique front bumper with new integrated daytime running lights near its outer edges and a narrower black honeycomb grille. 

GTX badging and the exterior mirror housings are finished in high-gloss black, and 21-inch alloy wheels are standard.

The rich ‘Cherry Red’ solid paint finish of the launch test car is exclusive to the GTX and it’s a fair bet many buyers will stump up the extra $4K required for a two-tone treatment, in this case with ‘Mono Silver’ as the highlight colour.

The interior is familiar ID.Buzz territory, with the long, broad dashtop pushing the windscreen and small front windows beside it into a quintessentially Kombi ‘bay window’-style design.

A 12-inch central multimedia screen sits proud of the multi-layered dash, and a slick 5.3-inch LCD instrument and car data display is fixed in front of the driver.

A black headliner dials up the sporty feel, the electric front seats are a GTX-specific design and the synthetic diamond pattern microfleece trim is highlighted by red contrast stitching and piping. 

The red cross-stitching extends to the steering wheel and smile-inducing stainless steel ‘play’ and ‘pause’ symbols on the accelerator and brake pedals are retained.

The sub-zero cool exterior design manages to merge with a more restrained and practical interior perfectly. VW has solid retro form with the ‘New Beetle’ from the 1990s and this primo ID.Buzz looks amazing. It drew an instant crowd of curious onlookers every time we stopped. 

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 ID.Buzz GTX is offered in shorter wheelbase variants with five- and six-seat configurations for other markets, but here it’s seven seats and long-wheelbase only.

At close to five metres long and just under two metres wide, it’s road-trip ready with heaps of breathing room for all seven occupants.

Placement of the gearshift on the right-hand side of the steering column frees up extra space in the front and there’s heaps of storage including a moveable (and removable) centre console unit between the front seats with pull-out drawers at either end, two trays in each door (the lower one offering room for multiple large bottles), a decent glove box and a fold-out dual cupholder unit.

There’s also an oddments shelf in front of the passenger, a wireless device charging slot in the dash and adjustable fold-down armrests on both sides of the front seats.

Pull the handle on the power-opening sliding side doors and the second row opens up with three seating positions offering hectares of room in all directions. 

This row can be moved 200mm longitudinally if a turf war erupts with those in the third row. And storage is great with two pockets and a fold out table on each front seatback as well as huge door bins with waste baskets included. There are also adjustable vents with temperature control in the roof.

There’s enough head and legroom for adults in the third row although the backrest is relatively upright. Even access is straightforward and there are numerous storage trays, cupholders, air vents and storage slots back there.

Power across the cabin runs to two USB-C ports in the dash, another in the front passenger area and four USB-C charging sockets in the rear.

Boot space increases from a handy 306 litres with all seats up to 1340 litres with the 50/50 split-folding third row down, and 2469L with it and the 60/40 split second row lowered. That’s plenty.

And that 1.6-tonne braked trailer towing capacity means a jet ski, even a mid-size camper trailer, is within hauling range.

The power tailgate is welcome and the rear of the boot’s load platform sits above two storage boxes. But you won’t find a spare of any description back there; a repair-inflator kit is your only option. So beware, a flat could really suck the air out of this mobile family room.

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 GTX is a twin-motor AWD, the front unit generating 80kW/134Nm and the rear 210kW/560Nm. Total output is 250kW/590Nm which boosts towing capacity from 1.0-tonne in the single-motor ID.Buzz to 1600kg.

A single-speed transmission sends drive primarily to the rear wheels to maximise efficiency, the dual-motor set-up able to direct power to the front axle as required during acceleration or to manage available traction.

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 ID.Buzz GTX’s 86kWh lithium-ion battery delivers a claimed (WLTP) range of 473km and the car uses a CCS Type 3 socket. VW includes a Mode 2 and Mode 3 cable as standard.

The claimed 10-80 per cent 200kW DC fast charge time is 26 minutes, while the same top-up takes nine hours at a maximum 11.0kW AC capacity.

Claimed energy consumption on the combined (urban/extra-urban) cycle is 20.2kWh/100km (WLTP) and over several hundred kilometres of mainly B-road and freeway running on the launch we saw an average of 24.5kWh/100km, which isn’t out of order given the type of driving involved.

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.

Despite the fact that it weighs in at around 2.8 tonnes (2780kg), Volkswagen Australia says this dual-motor ID.Buzz accelerates from 0-100km/h in 6.4 seconds and on to a 160km/h maximum velocity, if you dare. 

And there is always some serious oomph lurking under your right foot. Trundle along at 65km/h, pin the accelerator, and in roughly two blinks of an eye you’re doing 95km/h. 

Proportionally, this car is like a loaf of bread on wheels - about as high as it is wide. And on the windy launch drive we were buffeted a bit, the car moving sideways slightly when hit with a gust. But overall, it remains stable despite its proportions. That said, some wind noise comes over the bluff nose on the freeway, but never to an alarming degree. 

The ID. Buzz rides on VW’s Modular Electric Drive (MEB) platform and there’s been past criticism of the short-wheelbase versions' ride quality, but there are no such issues here.

Suspension is by struts at the front and semi-trailing arms at the rear and this GTX has had a suspension retune with particular attention paid to key components, including the dampers.

On rural roads that have seen better days, dotted with potholes, bumps and thumps, a combination of that suspension retune and the longer wheelbase helped the GTX handle it well. 

There are five drive modes with Comfort the default. Eco smooths out acceleration, tapers the climate control and reduces overall power, while Sport dials up the powertrain, suspension and steering. Traction optimises the AWD system for loose or slippery surfaces and Individual allows you to cherry pick various attributes for a custom set-up.

Steering is progressive rate and you can feel it loading up nicely as you head into a corner. Not the last word in terms of road feel, but the car points accurately and turn-in is nice and progressive.

At the same time you’ve got the electric motors constantly shuffling drive between the front and rear axles, helping you out if you decide to explore the car’s sporty nature and have a crack in the corners.

Tyres are Hankook Ventus S1 Evo3 EV specials (235/45 fr - 265/40 rr) and in long, sweeping bends, taken at pretty decent speed, they grip hard. Even on coarse-chip B-road surfaces there’s a bit of rumble but it’s far from a roar.

Braking is by large (358mm) ventilated discs in the front and, believe it or not, drums at the back. A well-designed, modern drum brake can work effectively and the regenerative braking in an EV like this is a big factor in terms of washing off speed.

In terms of lower speed manoeuvres, you’ve got a 360-degree camera view as well as a reversing camera and front and rear parking sensors. If you really need some help, Park Assist Plus will get the job done for you.

In terms of ergonomics, we spent hours behind the wheel and the front seats remained comfortable and supportive in terms of lateral grip.

Speaking of grip, the steering wheel is nice to hold. And the cool little 5.3-inch instrument and car data display is clear as a bell, and the large 12-inch media screen is easy to use and working through the different screens is largely intuitive.

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.

The ID.Buzz GTX is covered by Volkswagen Australia’s five-year/unlimited-km warranty with two years’ roadside assistance included. On top of that, there’s an eight-year/160,000km warranty on the drive battery.

That general warranty is in line with the mainstream market, although it’s worth noting an increasing number are stepping up to longer terms, including 10 years.  

There’s a 12-year corrosion perforation warranty and keep servicing with an authorised VW dealer and that roadside assistance support will be rolled over for another two years each time.

The recommended maintenance interval is two years/30,000km. Standard scheduled service pricing is $687 for each of the first five workshop visits, while pre-paid plans covering six, eight or 10 years represent savings of between 30 and 35 per cent on that figure, which is pretty handy.

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.
