Audi S6 VS Mercedes-Benz E63
- Executive style
- Improved value
- Boy-racer performance
- Not SUV practical
- A touch thirsty
- Substandard warranty
- Incredible performance, easily accessed
- Amazing duality between performance and luxury
- Relatively subtle looks for battling tall-poppy haters
- No wagon version for Australia
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.

|Fuel Type||Hybrid with Premium Unleaded|
The faster you go, the less comfortable things become. Any race car will prove this theory, and the current C 63 S AMG also backs it up with its, shall we say, 'performance-focused' package.
As you’d expect, its mighty E 63 S bigger brother is faster again. But surely it can’t afford to be less comfy than its C-Class sibling, particularly when it adds more than $80k to the sticker price and typically appeals to a more mature audience.
And sure enough, it isn’t, but rather than simply becoming the larger equivalent of the C 63 S, the new fastest E-Class somehow has enough bandwidth to satisfy expectations of three-pointed-star luxury and boast more performance than any four-door AMG ever.
Oh, and it’s also all-wheel drive (AWD) for the first time in Australia. None of this seems to add up, so how have they done it?
|Engine Type||4.0L 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.
The new E 63 S is proof that you can be supercar quick without having to feel like you’re in a racecar all the time.
It’s hard to find a single thing wrong with it once you’re past the near-quarter of a million dollar asking price, but even that’s more than 10 grand cheaper than before.
The only thing I’d like to see is the wagon version in Australia, but not enough us want to buy one.
In my opinion, it’s the best four-door AMG you can buy, and the new M5 will have to be pretty amazing to topple it.
Would you be happy to park an E 63 S in your garage, or would you wait to see how good the new M5 is? 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.
Like the C 63 S, the easiest way to pick the E 63 S is by its bespoke front air dam, pumped front guards and the AMG-characteristic double-bulge bonnet. To the uneducated, it looks little more than an AMG-kitted lesser model, but is smartly distinguished from the regular body treatment.
No doubt a lot of $200k-plus performance sedan buyers would prefer it this way, instead of a giant rear wing and a bunch of extraneous vents to underline its supercar-like capabilities.
The wheels are unique to the E 63 S, with the 20-inch cross-spoke forged design measuring 9.5 inches wide up front and a full 10 inches at the rear. That’s as wide as Brocky’s Group C Torana A9X racer by the way, yet they snugly fit within the standard rear wheel arches.
The interior isn’t too far removed from a regular E-Class either - which is already a pretty swish place to be - but gets grippy, hard-backed 'Performance' seats, Alcantara grip sections and a straight-ahead marker added to the AMG steering wheel, plus a smattering of AMG logos.
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.
No supercar will ever be as easy to live with as the E 63 S, with the passenger-car requisite two cupholders front and rear with bottle holders in each door, ample legroom and headroom for rear-seat passengers, and a 40/20/40 split-fold back seat leading to a cavernous 540-litre boot.
The E 63 S’s Performance front seats do lose their map pockets, though.
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.
With a list price of $239,611, it’s more than 2.5 times the price of a base E200, but Mercedes boasts that it’s also more than $10,000 cheaper than the model it replaced in May 2017, with a lot more equipment fitted standard.
This still puts it $82,000 higher than a C 63 S sedan and $80,000 more than the quite-quick V6 E 43, and a full $30,000 more than the regular E 63 that joined the range in December.
Whether the E 63 S’s extra fruit is worth it is up to you, but Mercedes expects most E 63 buyers will opt for the S.
Its extensive list of standard kit helps to justify its ask somewhat, with the only concession for performance being the deletion of the PRE-SAFE Impulse Side system because of the more sculpted Performance seats.
Our E 63 S was also optioned with $4200 worth of designo Selenite Grey magno matte paint, and the ceramic composite brakes signified by the gold calipers add a further $9900.
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 E 63 has also followed the C 63 in bucking the “no replacement for displacement” adage, dropping 1.5-litres over the model it replaced but gaining 20kW/50Nm for new totals of 450kW/850Nm.
This is thanks to an uprated version of the 4.0-litre twin turbo M177 V8, which is paired to a multi-plate clutch version of the excellent nine-speed auto for the first time.
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.
This area is unlikely to be a top priority if you’re shopping for a $240k V8 performance saloon, but the E 63 S’s 9.3L/100km official combined fuel figure should catch your eye if it is. We experienced 11.6L/100km on test, which is pretty amazing given how tempting that throttle pedal is.
Also helping to forgive this temptation is a bigger 80-litre fuel tank (20-litres more than the base E-Class) which promises a comfortable range between fills.
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.
Push the start button and the ensuing rumble will annoy your neighbours if you leave for work early. This has come to be an AMG V8 trademark, but even with the exhaust button’s ability to liberate a few more decibels, it’s still a smidge more discreet than the C 63 S.
Not all AMG exhausts are created equal you see, with the E 63 S’s particular flavour sitting somewhere between the C and the SL tune, based on my recent experience.
What you’re left with is still up there with the industry best, with the range of tunes from angry burble to pops and cackles on overrun setting the scene well for the E63 S drive experience.
Range is a key word when it comes to the E 63 S, with an incredible 0-100km/h claim of 3.4 seconds headlining the performance end of its personality. This is a full six tenths faster than the C 63 S sedan, and it feels every bit of it.
It’s difficult to articulate just how fast this is, but bear in mind Ferrari’s mid-noughties F1 racer for the road, the Enzo, carried a 3.6 second claim. The E 63 S is 0.2s faster than that!
The AMG’s full 850 Newton metres are available from just 2500rpm (to 4500 for the record), making any prod of the accelerator very effective.
The nine-speed auto doesn't fail to impress either, with fast and responsive shifts in the sportier drive modes, with none of the slow-speed lag or shunting and clunking you tend to get from some rivals' dual-clutch units.
Helping all those Newtons get to the ground is the fully active AWD system, which has been set up to preserve the AMG-characteristic tailiness with a 31:69 default torque split front to rear.
Controlling the apportioning of power side-to-side is an electronic rear-axle limited slip differential (as opposed to the regular E 63’s mechanical unit), and the net result will let the rear end hang loose just enough before the torque vectoring sends more power to the front to pull you back into line.
Unlike pretty much every AWD system this side of a ute, the E 63 S is able to send 100 per cent of its power to the rear wheels when ‘Drift Mode’ is engaged, with Race selected from the drive menu.
This also means deactivating the stability and traction control altogether, flicking the transmission to manual mode and pulling on the shift paddles, but in the interests of retaining employment and my general wellbeing, we’ll save Drift Mode for the race track.
Another claim we’ll have to leave purely theoretical is that the speed limiter has been relaxed by 50km/h to permit a full 300! This is a large four-door sedan, remember. How very German.
The abundance of aluminium in the W213 E-Class shell has led to a feeling of lightness that I feel detracts from the classic E-Class ‘bank vault’ sensation in the lesser models, but this actually works in the E 63 S’s favour.
At 1955kg, it’s a full 300kg heavier than the C 63 S sedan, but doesn’t really feel it. Granted, a lot of that weight would be down low, due to the AWD system, but it retains a general feeling of lightness and a willingness to change direction.
Also helping are bespoke front suspension architecture for a wider track and more hardcore geometry, a unique steering column, and the S also gets hydraulic engine mounts that tighten up to sharpen feel in the more aggressive drive modes.
Grip from the 265mm wide front tyres and 295mm rears is fantastic, but they will break away gently to give confidence when driving at the limit. This also makes a bit of tail wagging out of corners a lot less nerve-wracking.
The ceramic composite brakes fitted to our car also do an excellent job of reighning in all that performance quickly and consistently, and unlike a lot of similar setups they don’t squeal when cold.
Beyond this outstanding performance and driver appeal, the E 63 S’s trump card is its ability to return to regular E-Class luxury at the flick of a switch - back into Comfort mode.
The airbag suspension is arguably what is most responsible for this duality, but it’s also a sign of all the mechanical components being developed together to work in harmony, with such a spectrum of ability being targeted from the get-go. This is not an E-Class with AMG mods, this is an E-Class that’s been designed to be an AMG from the beginning.
Adding a “but wait, there’s more” edge to the E 63 S’s drive experience is the fact that like all versions of the new E-Class, the active safety systems work together to enable Drive Pilot semi-autonomous driving, which represents Level 2 autonomy.
This means you can drive down a motorway with only an occasional touch of the steering wheel as an input, and it will even change lanes if the indicators are activated. As amazing as they are, we recommend exercising great caution when using these features, however.
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.
Like all versions of the W213 E-Class, the E 63 S carries the maximum five-star ANCAP (tested 2016) and EuroNCAP safety ratings. A brilliantly integrated suite of active and passive safety features go well beyond its standard AEB, nine-airbag count, 360-degree parking cameras, rear cross-traffic alerts, and a pedestrian-protecting active bonnet.
The only slight compromise is the deletion of the PRE-SAFE Impulse Side system which moves the occupant away from a collision if a potential side impact is detected.
This is because of the E 63 S’s standard “Performance” front seats, but the system is restored if the less sculpted “sport seats” are optioned through the Active Comfort package.
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.
As with all Mercedes passenger cars, the E 63 S is covered by a three-year, unlimited kilometre warranty. Service intervals are either 12 months or 20,000km and the first three services are capped at $736, $1472 and $1472 respectively.
This compares with $668/$1356/$1356 for the E 43, and 456/912/912 for a base E200, and the latter two models have 25,000km intervals.
