Audi S4

Summary

Mercedes-Benz S-Class

Ever since the middle of the 1990s, I've been captivated by the Mercedes-Benz S Class. It used to be known as Sonderklasse - special class - and teenage me certainly thought it was. The one that caught my attention was the W140. A huge, two-tonne beast when that sort of mass was rare, it was loaded with amazingness and owned the road.

Part of its unique appeal was that that it was properly ugly. When it hove into view it was like a battleship entering Sydney Harbour. And it used almost as much fuel, with the V12 on board.

Over the years, genuine style has invaded the S-Class and today I found myself, for the first time, in an unusually pretty pair of S Classes - the S560 and S63 Coupes. And, astonishingly, it's the first time I've ever driven an S-Class. So with all that baggage I've built up over the years, they had a lot to live up to.

Audi S4

Peter Anderson road tests and reviews the new Audi S4 sedan and Avant, with specs, fuel consumption and verdict at its Australian launch between Bathurst and Canberra.

Sometimes year a year flashes by and it's almost a shock to realise that Audi's B9 A4 has been with us here in Australia for almost that long. Performance buffs have had to wait for the first quick version of the A4 while the Allroad was rolled out, but here we finally have the first Audi Sport variant in the line-up - the S4.

As with the standard A4, there's a stack of new stuff and a stout standard specification list along with technical packages. There's one big piece of news, too - it's the first S4 to land with a price tag under $100,000.

Verdict

Mercedes-Benz S-Class7.3/10

Both of these vast vehicles are phenomenally comfortable - this is the kind of car that Mercedes does so well, and has done for decades. The S Class is rarely a disappointment but it's difficult to believe that such a big, heavy GT car can also dance the way the S63 does.

The S560 is far more weighted to being a GT - supremely comfortable with that active suspension, a growly, refined V8 and a cabin full of gadgets and comfort. The S63 is altogether more aggressive, to look at and to drive. Lopping the roof off both of them adds weight but, like any cruiser, also puts you out in the sun, the breeze and into your surroundings. Plus, in the case of the S63, you get more exhaust noise.

They're two very different cars and not just because of the engine. After all these years admiring it from afar, the S63 has delivered on my teenage expectations - fast, smooth and utterly mad.

Is the S Class still the car that springs to mind when you think ultimate luxury? Or has another brand taken its place? Tell us what you think in the comments below.


Audi S47.5/10

It's not an exuberant machine and you can tell there's still a ton of room for the inevitable RS4 mean machine to go after the BMW M3/M4 and AMG C63. That means, however, that the S4 is a proper sleeper. Hardly anyone will notice what it is until they're eating your fumes while you whisk yourself away in (mostly) quiet and comfort.

The new S4 is lighter, slightly faster and more technologically advanced than its predecessor, while bringing the A4's charms to the go-faster part of the executive sedan segment. This one will rattle a few cages.

Design

Mercedes-Benz S-Class7/10

The S Class Coupe is obviously related to the sedan but manages a svelte appearance. Slimmer hipped and with a more Coke-bottle shape, the Coupe - if you squint a bit - has a bit of the classic old pagoda about it. Obviously you can't do pillars that slim anymore, but the glass roof takes away some of the visual weight inside and out. 

The cabriolet's roof is nicely integrated and looks good when it's  up, which isn't always the case.

They all look long, though. It's obvious to see why the cars all run on 20-inch wheels - anything smaller would look hilarious.

The cabin is a fairly sensible re-imagining of the E-Class. The big twin-screen layout of the dash and multimedia system seems a bit more at home here. The chintzy Burmester speakers in the doors let down an otherwise classy cabin, which steers clear of otiose vulgarity in looks and materials.


Audi S48/10

Audi tells us that S4 owners don't like to shout about their purchase, which is just as well, because the S4 looks like a very mildly gussied up A4. That means the same sharp looks as the A4 but lower, 23mm to be exact. The standard 19s make it look lower still but all the standard A4 cues are there. This has been covered at length already, but just to be sure, every inch of the car is new, it just looks a lot like the old one.

Get up closer, though, and you'll see the serrated shape of the headlight, the clamshell bonnet and shutlines tighter than Scott Morrison on Budget night when it comes to funding hospitals. Audi says the body kit is aggressive but I think it's safe to say that the drug of choice at Audi's styling bureau is chamomile tea - it's fairly restrained, with just a few details (including a slightly daggy V6T badge on the front guards) to mark it out.

Inside is standard A4, too, with plenty of leather (both real and man-made), with some extra zing in the form of carbon and aluminium bits.

It's as roomy and comfortable as the standard car and looks just as good. It's a fine interior, the best in its class.

Practicality

Mercedes-Benz S-Class6/10

Well look, if you end up in the back of the S Coupe, it's not a riot of space. Obviously it has back seats (the SL doesn't even squeeze a jump seat into its considerable length) but they're for occasional, if luxurious, use.

The boot is a reasonably decent 400 litres, obviously the cabriolet loses a few litres with the roof folded. Front and rear passengers will both enjoy a pair of cupholders and the whopping long doors will each hold a bottle.


Audi S47/10

The S4 has four bottle holders, cupholders front and rear for a total of four and various slots and spots for phones and keys in the front while the rear is a little less accommodating of bits and pieces.

The sedan's boot is the same as the rest of the A4s (and mid-size Germans) at 480 litres while the Avant bumps that up to a 505 litre minimum and a 1510 litre maximum when you drop the seatbacks.

Price and features

Mercedes-Benz S-Class7/10

One thing hasn't changed in nearly 20 years - the S isn't cheap. Available in coupe and cabriolet, the S560 starts at $314,900 for the former and $336,900 for the latter. Step up to the S63 pair and you'll pay from $370,500 for the coupe and $399,900 for the cab. If you're super keen for something spectacular, the twin-turbo V12-powered S65 is available for between $508,900 and $520,500, and features Swarovski crystals in the headlights, for some reason.

As you can imagine, there's quite a bit to cover, so for both cars I'll stick to the edited highlights. The S560s roll on 20-inch alloys, has a 590-watt 13 speaker sound system, digital TV, auto parking, active cruise control, panoramic glass roof, Nappa leather, active seats and power-closing doors.

It also comes standard with a heating pack that not only heats the seats but the steering wheel and centre console. In the cabriolet you also get the 'Airscarf' neck heater.

Both cars also feature's Mercedes' Magic Body Control with curve function. More of that wacky feature later.

The S63 AMG is a step up in power, price and spec. One notable change from the S560 is the loss of 'Magic Body Control', which is replaced with mere air suspension. The 20-inch alloys are 10-spoke forged units, the brakes higher performance composites with red calipers, while an AMG sports exhaust brings the noise.

Naturally, both are swathed in high-quality leather and feature dual-zone climate control, heated and cooled electric seats that adjust in every direction, deep carpets, keyless entry and start, fully digital dashboards and just about every gadget to which you can point your imagination.

Entertainment and sat nav are via Mercedes' 'Comand' system, which is displayed on a massive 12.3-inch slab of glass at the top of the dashboard. The 13-speaker Burmester-branded system is predictably impressive and with Apple CarPlay and Android Auto, you only have to use the basic software for the radio or various car controls.


Audi S48/10

The S4 is available in two versions - sedan and Avant wagon. The sedan opens the bidding at $99,900 and the Avant closes it at $102,900. Both come with identical specifications and are available with much the same options. For a bit of pricing perspective, the first S4 was an Audi 100-based five-cylinder turbo that landed with a price tag of $132,000. In 1993.

The S4 has arrived with 19-inch alloys, adaptive dampers, around-view camera, reversing camera, up-spec sat nav, adaptive cruise control, auto parking, auto headlights and wipers, high beam assist, keyless entry and start, electric tailgate (Avant only), heated folding electric mirrors, LED headlights, dynamic scrolling rear indicators, electric heated sports front seats, leather and Alcantara trim, three-zone climate control and interior LED lighting.

A ten speaker stereo is powered by Audi's MMI rotary dial system and the same 8.3-inch screen as the rest of the A4 range, which also means you get Apple CarPlay and Android Auto as well as two USB ports in the centre console to go with the Bluetooth. There's also a DAB+ digital radio

Audi's Virtual Cockpit is standard and has an additional S mode which switches the dial view for a big tacho and a huge digital speed readout.

Being an Audi, you can get a collection of options in packs. The S Performance Package ($5900) adds an excellent pair of massaging S sport front seats with diamond stitching and Nappa leather, red brake calipers, more (synthetic) leather and carbon inlays in the interior.

The Technik Package adds the excellent matrix LED headlights, the 19-speaker B&O 3D sound system and a heads-up display.

Other options include variable ratio Dynamic Steering ($2210), quattro sport differential ($2950), premium paint (ahem, $1846), panoramic sunroof (Avant only, $2990), sunroof ($2470, sedan only), heated rear seats ($750) and the rear seat entertainment system ($2600-$4680 for one or two screens respectively, but you can't have it with the S Performance pack)

Engine & trans

Mercedes-Benz S-Class8/10

All four coupes and cabriolets ship with Daimler's formidable 4.0-litre twin-turbo V8. The S560 scores 345kW/700Nm to drive the rear wheels through Benz's own nine-speed automatic. With all of that available, the S560 will crack the ton in 4.6 seconds and make a wonderful racket on the way.

Moving on to the S63, the same engine delivers a massive 450kW/900Nm. The run from 0-100km/h is dispatched in just 3.5 seconds and if I thought the S560 made a good noise, the S63 with its standard sports exhaust makes a better one. Again, Mercedes' nine-speeder is along for the ride.


Audi S47/10

Audi says the turbocharged V6 is brand new from the ground up. Developing 260kW (15kW up) and a nice round 500Nm (up 60Nm), the new engine is 14kg lighter than the supercharged unit it replaces, and more efficient.

Efficiency gains come from clever things like a "hot side inside" turbo placement (inside the V, meaning shorter exhaust paths to better turbo pressure), lift-off coasting and start-stop.

Power reaches the road via an Audi Sport tweaked quattro system which can send 85 percent of power in either direction and is rear-biased with a standard 60/40 rear/front torque split. The seemingly ubiquitous and always excellent eight-speed ZF transmission handles the job of getting the power from the engine to the road.

The standard self-locking centre diff can be flung and replaced with a trick quattro sport unit ($2950) with electro-mechanical control of the rear axle's torque split.

The sedan will rocket to 100km/h in 4.7 seconds, the slightly heavier Avant two tenths behind it.

Fuel consumption

Mercedes-Benz S-Class7/10

The lower-powered 560 drinks 98RON at the rate of 8.5L/100km for the coupe and 9.9L/100km for the heavier cabriolet.

The S63 ups the ante with 9.9L/100km for the coupe and an identical 9.9L/100km for the cab.

Our launch program contained some...er...spirited driving, which would explain the mid to high-teens fuel figures.


Audi S47/10

Audi claims 7.7L/100km from the sedan and 7.8L/100km for the Avant. On a stinking hot day in central NSW and the ACT and with the accelerator spending a lot of time carpet-bound, the S4 still returned around 12L/100km. More time being driven less enthusiastically should see a marked improvement.

Driving

Mercedes-Benz S-Class8/10

Let's start with the S560. That smooth V8 rumble is all you'll ever hear if you just slot into drive and go for a leisurely spin. The nine-speed automatic continues to be a revelation to me - in the GLC63 it's good and here, once again, it's excellent, finding the right gear for the occasion and riding the fat torque curve. Other nine-speed autos are not very good at all.

The test route for the S560 played to the strengths of the car. It had some lovely winding roads, which brought the trick suspension into focus - the Magic Body Control with curve function is hilarious. While the active suspension works hard at all times to ensure the ride is smooth and drama free, the Curve mode (no, really) actually leans the car into corners.

Those of you who remember the video game Wipeout 2097 will be big fans of Curve mode. As you approach a corner, you turn the wheel and then the car leans into the bend. This isn't active damping reading the road, it's the outside suspension lifting the car and the inside lowering it, so the car feels like it's gliding, like a hovercar. It's wild but oddly calming. Mercedes reckons it's great for those who get car sick. As I didn't have my wife on hand to test this theory - she chucks at the first sign of a corner - I couldn't verify this claim. That will have to wait.

The S63 AMG is a completely different proposition. The air suspension is more than up to the job of helping smother the effects of the car's considerable weight, meaning that no matter what you're up to, the car feels reasonably light on its feet. It never feels small, though, commanding the respect of the driver and plenty of space from other road users.

And boy, do you need some space if you kick the S63 into Sport mode. In true AMG style, the electronic reins relax and the big luxury coupe cheerfully kicks off. The tail will wriggle under an unsympathetic right foot, that signature V8 roar, crackle and hiss filling your ears. The S63 is always the harder-feeling car, but it delivers with a more sporting drive than the S560.

Being the generous soul I am, I volunteered to return the S63 to its home for the evening rather than consign it to the back of a truck. On the back roads I took to reach the highway, it was rock solid - fast, predictable and a lot of fun. Once I found the boring straight bits, it turned into a supremely comfortable cruiser, ticking along in ninth at the legal limit (and being Melbourne, it was very much the legal limit), dispatching overtaking with barely a flex of a toe. 

The active cruise took the stress of keeping away from the State Revenue Office's clutches while being quiet and utterly pleasant.


Audi S47/10

The S4 is terrific fun. It's that simple. The new engine is an absolute belter, with all 500Nm of torque available at just 1370rpm. Lag is almost indistinguishable as the turbo spools up and rockets you along to 100kmh in under five seconds, that huge half-ton of torque sweeping you down the road.

With dynamic mode switched on, the car muscles up with firmer suspension and a slightly growlier exhaust. The steering really weights up, too, which takes a little getting used to after the lighter, friendlier setting in Comfort mode - thankfully you can set up an individual mode to dial the assistance back in while everything else is set up for go-fast.

The key to the fun is the rear-biased quattro system - while it's never going to match the purity of BMW's rear-wheel drive 340i, what you lose in steering feel and ultimate adjustability, you gain in off-the-line and mid-corner grip its German rivals could only dream of.

Going fast in an S4 is easy, leaving you to concentrate a little more on your line and gear selection, listening to the distant bark of the engine and the occasional turbo whistle. All of this is purely down to driving taste, of course but the point is, the S4 offers something a little different to the other two. 

For most of the time the S4 defies its 1700kg-plus weight but there is the occasional hesitancy when changing direction through a challenging set of bends, as though the front tyres (245s all around, if you're interested) want to scrub and the quattro system makes a quick adjustment to stop it happening. You don't feel that's what's happening, of course - Audi Sport is better than that - but it's part and parcel of all-wheel drive. It takes a lot to find understeer and for most people, that just won't ever happen.

Further confidence comes from the terrific brakes - 350mm up front and 330mm at the rear, the big forward rotors are gripped by six-pot fixed calipers. Performance is epic and in hard, fast driving they stood up to a fair amount of punishment without fading.

The ride is excellent in all modes, which is quite an achievement given the fat rubber and big wheels, although big bumps at speed make a huge metallic thunk without actually upsetting progress. The eight-speed ZF is brilliant as always and unless you're really motoring, you don't even need its sport mode, which brings impressively fast and positive shifts.

The best thing is, if you don't look in the rear vision mirror, you can't really tell if you're driving sedan or Avant. That might be because it's quite absorbing on a launch drive, but I couldn't split the driving experience between the two.

The only black marks I could easily identify on the S4 is tyre noise on some surfaces and perhaps the steering could be a little more lively like its competitors.

Safety

Mercedes-Benz S-Class8/10

The S-Class coupe comes loaded with eight airbags, ABS, stability and traction controls, forward and reverse AEB with pedestrian detection, reversing camera, crosswind assist (I know, right?), traffic-sign recognition and reverse cross traffic alert.

The S-Class Coupe does not have an ANCAP or EuroNCAP rating.


Audi S49/10

Eight airbags, ABS, stability and traction controlAEB at the front, lane departure warning, lane keep assist, driver attention detection, reverse cross traffic alert.

The S4 also retains the exit warning feature that tells you if you're about to door an approaching bicyclist or another car. What Audi calls "pre-sense rear" is a system to warn drivers behind you they're approaching too fast and are quite likely to hit you. Turn assist is also available, stopping you (at low speeds) from turning across approaching traffic.

The A4 scored five ANCAP safety stars, the highest available.

Ownership

Mercedes-Benz S-Class7/10

Mercedes offers a three-year/unlimited-kilometre warranty with roadside assist for the duration.

The company also offers both service plans (where you pay up-front as part of the vehicle purchase) and capped-price servicing on the coupes. Servicing over three years is in the order $2500.


Audi S47/10

Audi offers a three-year/unlimited kilometre warranty on the S4 with service intervals of 12 months or 15,000km whichever comes first. Roadside assist is part of the package, lasting for the first three years of the car's life.

You can pre-purchase three years/45,000km of servicing for $1620 under Audi's Genuine Care Service Plan. Full details are available on Audi's website, but it basically covers a scheduled oil changes and inspections and not a lot else.
