Porsche 911 vs Audi S5

What's the difference?

In describing this 911, Porsche talks about the 'T-feeling'. It should be light and agile, delivering fun, driving pleasure, yet still suitable for everyday use.

Sure, the safety could be better and the warranty lags the market, but that stuff fades into the background when the T feeling takes over. What a great car!

The S4 and S5 range continues to represent a great formula for performance you can live with every day. They're arguably the sweetest balance Audi produces, actually. All come fantastically equipped, with cabins that feel truly special, and we’re lucky they can be had in a choice of five bodystyles.  

One of the most recognisable profiles in the automotive world, the 911 has evolved and grown over time but there's no mistaking it for anything other than Zuffenhausen's finest.

For the record, the current '992' 911 is a whopping 367mm longer, 242mm wider and 30mm lower than the 1963 original. And the majority of models share the same (1852mm) wide-body look, the Turbo and GT3 RS broadening that to 1900mm.

Multiple solid and metallic colours are available at no extra cost, three of which are exclusive to the Carrera T, but if you like our test car's 'striking' 'Python Green' finish, it'll set you back an extra $5700.

Car-spotters on the lookout for the Carrera T will need to tick off 'Agate Grey' accents on the tail-light grille, badging and mirror housings as well as a grey top tint windscreen, specific side graphics and Carrera S wheels in 'Titanium Grey'.

The cabin in our test car also has also been optionally upgraded with the 'Carrera T Interior Package' ($4120), which adds extra leather trim as well as coloured seat belts and contrast stitching.

Our car has also picked up the 'Adaptive Sports Seats' ($5510). Subjective call, of course, but I love the dark cloth seat inserts with tiny flecks of green. It's Porsche retro-cool, but somehow contemporary at the same time. Beautiful.

And the five-dial instrument cluster under a gently curved cowl is a 911 design signature, although the central tachometer is now flanked by twin 7.0-inch, configurable displays.

Ergonomically and aesthetically, this layout is hard to fault.

The S4 sedan and Avant have scored the bulk of design updates, with all new and recontoured side panels including the sedan’s C-pillar matching what was applied to the A4 earlier this year. 

This is paired with new front and rear facias and lighting for a subtle but extensive rework of the fifth-generation S4’s conservative look. 

The S5 Sportback, Coupe and Cabriolet get S5-specific new lighting and facias, but no sheetmetal changes. As before, the Coupe and Cabriolet ride on a 60mm shorter wheelbase than the Sportback, sedan and Avant.

The S5s also get Matrix LED headlights as standard which do a neat animated sequence when you unlock the car. 

Other visual hallmarks include new S4-specific 19-inch wheels, with S5 stepping up to its own unique 20-inch wheel. The six-piston front brake calipers are appropriately painted red, and there’s S-specific adaptive dampers under there too. All variants aside from the Cabriolet get a lip spoiler on the rear.

On the inside, there’s a new centre console and bigger 10.1-inch multimedia screen, while the Audi Virtual Cockpit driver instrument display now offers a hockey stick-style rev counter in additional to traditional dial layouts.

Even though the current 911 dwarfs the original '901' series of sixty years ago, it's still aimed primarily at accommodating the driver and front passenger, with '+2' rear seating a handy addition for kids, or adults in short trip emergencies.

In other markets, the addition of the rear seats is a no-cost option, whereas here they're the default fitment and removing them is the zero-dollar choice. Which makes sense because they add significantly to the car's usability.

Either way, a sports car of this type is never going to be SUV practical. However, when you look at it in the context of the Carrera T's competitors, this 911 does pretty well.

It feels appropriately snug inside, yet there's more than enough breathing space in the front and a liveable distance between driver and passenger.

For storage there are two slim compartments in each door, with a cavity for bottles, as well as a cupholder in the centre console and another pop-out holder in the dash on the passenger side.

As in most 911s, you can swap the centre console cupholder out with a small oddments tray insert which is a nifty piece of practical thinking.

There's also a modest glove box, a shallow lidded compartment between the seats and clothes hooks on the front seat backrests.

Connectivity and power options run to a pair of USB-C ports in the centre console box and a 12-volt outlet in the passenger footwell. Nothing in the back, which isn't a big surprise.

And the 132-litre boot is the only substantial cargo space, with enough room for several soft bags or a medium suitcase… even a mid-week grocery top-up.

Luggage-type storage inside the car is helped by the rear seat backs folding down to create a level platform.

But bear in mind there's no spare. A can of sealant and air compressor are on board instead.

The biggest practicality change among the five S4 and S5 variants is their upgrade to the latest version of Audi’s MMI multimedia system, which steps up to a 10.1-inch touchscreen and drops the scroll wheel from the centre console.

It also boasts ten times the computing power of the version it replaces and uses this and an on-board sim card to access Google Earth maps for navigation and Audi Connect Plus that offers driver information such as fuel prices and parking information as well as point of interest search and weather information, plus the ability to make emergency calls and seek roadside assistance.

There’s also a wireless phone charger, but using Apple CarPlay will still require a cord as per Android Auto.

I only drove the S4 Avant and S5 Sportback at their media launch, which are clearly the most practical of the five, but from our experience with the previous versions, each looks after its occupants well in terms of space and storage. Back seat accommodation is clearly not a priority in the Coupe and Cabriolet, but there’s three other variants if that’s what you’re looking for. 

The Cabriolet can open its automatic folding soft top within 15 seconds, at speeds of up to 50 km/h.

As I mentioned above, the S4 and S5 line-up are in many ways the same, but also different, and these differences result in a price span of $20,500 between the S4 sedan and the S5 Cabriolet. 

The former is now $400 cheaper with a list price of $99,500, with the also-$400 cheaper S4 Avant not far beyond at $102,000.

The S5 Sportback and Coupe are now $600 more expensive at an equal list price of $106,500, while the swish folding soft top of the S5 Cabriolet pushes it up to $120,000 (+$1060).

Equipment levels are consistent across all five variants aside from the S5s getting Matrix LED headlights as standard and one inch larger 20-inch wheels. 

Key details include Nappa leather trim with front sport seats with seat heaters and massage function, a Bang & Olufsen sound system which spreads 755W across a total of 19 speakers, brushed aluminium inlays, head-up display, coloured ambient lighting, tinted windows and metallic paint.

Over the past 12 months, the S5 Sportback has proven to be the most popular of the five variants by far, accounting for 53 per cent of sales, with the S4 Avant next in line at 20 per cent, the S4 sedan making up 10 per cent, and the S5 Coupe and Cabriolet combining to make up the remaining 17 per cent.

One of the saddest things about recent 911s is the fact that when you open the cover you can't see the engine unless you decide to break out the spanners and remove everything that's hiding it.

If you did, you'd reveal a 3.0-litre, all-alloy, dry-sumped, twin-turbo flat six-cylinder engine which remains unchanged from the entry Carrera model.

Featuring direct-injection and variable valve control, it sends more than 280kW (380hp) and 450Nm (from 1950-5000rpm) to the rear wheels through a seven-speed manual gearbox, or in this case, the no-cost optional eight-speed dual-clutch auto.

Suffice it to say, in a car weighing less than 1.5 tonnes, that's plenty of propulsion, and even though an engine hanging over the rear axle remains a peculiar 911 throwback, the white-coated boffins in Stuttgart continue to make it work brilliantly well.

Audi has taken an ‘if it ain’t broke’ approach with the mechanicals, with all S4 and S5 models unchanged with this update. So the centrepiece continues to be the single-turbocharged 3.0-litre V6 that produces 260kW and 500Nm, with the latter available from a broad 1370-4500rpm.

The rest of the drivetrain is also unchanged, with the venerable but excellent ZF eight-speed torque converter auto paired with the Quattro all-wheel drive system that can send up to 85 per cent of drive to the rear wheels. 

Porsche's official fuel economy number for the combined (ADR 81/02 - urban, extra-urban) cycle is 10.8L/100km for the dual-clutch auto as tested, the 3.0-litre twin-turbo six emitting 246g/km of CO2 in the process.

During a week of city, suburban and some at times enthusiastic highway running, we averaged 15.0L/100km (at the pump), while the car's onboard computer indicated 16.1L/100km, which isn't out of line with the super- and turbo-charged V8s this car competes with.

Minimum fuel requirement is 98 RON 'premium' unleaded and you'll need 64 litres of it to fill the tank.

Using the official number, that translates to a driving range of around 590km, which drops to roughly 430km using our real-world figure.

Official combined fuel figures range from 8.6L1/00km for the S4 sedan to 8.8L/100km for the Avant, Coupe and Sportback, while the heavier Cabriolet steps up to 9.1L/100km. 

All are pretty good considering their performance potential and the size of these cars, plus the fact that they only require 95 RON Premium Unleaded fuel.

All have a 58-litre fuel tank, which should enable a range of at least 637km between fills based on the Cabriolet’s figure.

At 1470kg the 911 Carrera T is 35kg lighter than the entry-level car it's based on, thanks largely to reduced sound insulation, lightweight glazing and a more compact battery.

Yes, the rear seats are fitted to our test example, which sends the scales back up a bit, but the reduced sound deadening still raises the standard sports exhaust's glorious rumble through the cabin.

Porsche claims 0-100km/h in 4.0 seconds for the auto and 4.5s for the seven-speed manual. Yep, it's quick!

Peak torque (450Nm) is on hand from 1950-5000rpm, which means there's always substantial mid-range punch available, with the dual-clutch auto's eight ratios also helping to keep things on the boil.

I love a manual gearbox as much as the next person, but this dual-clutch is ultra fast yet refined with the wheel-mounted paddles adding to the fun.

The 'Driving Mode' dial on the steering wheel enables selection of 'Normal', 'Sport', 'Sport Plus' and 'Individual' modes, with each selection displayed in the instrument cluster.

And given the 'Sport Chrono Package' is standard the 'Sport Response' button in the centre of that mode dial acts like a push-to-pass function, delivering a 20-second burst of maximum performance response from the engine and transmission.

Suspension is by struts at the front and multi-links at the rear, with ride height dropped by 10mm and the standard 'Porsche Active Suspension Management' (PASM) system able to adjust the dampers through 'Normal' and 'Sport' modes.

Ride comfort is harsh, even in the most comfort-focused setting, but that kind of goes with the Carrera T territory.

The steering is pretty much perfection. Precise and accurate, with amazing road feel, it allows the old 'think your way through corners' syndrome.

Speaking of which, this car chews up and spits out twisting B-roads without a hint of drama. The front end sticks and refuses to let go, the big 305 rear rubber following suit.

It remains resolutely planted, balanced and adjustable on the throttle, the standard torque vectoring set-up and locking diff turning go-fast wannabes into bonafide apex predators.
  
Standard rubber is Z-rated Goodyear Eagle F1 (245/35x20 fr - 305/30x21 rr) which is 10mm wider than the already generously shod 911 Carrera.

Braking is suitably beefy with 330mm ventilated and cross-drilled rotors all around clamped by four-piston aluminium monobloc fixed calipers front and rear.

We got the bit between our teeth at various stages of this test and can confirm the brakes are able to wash off speed rapidly and consistently with a reassuringly firm yet progressive pedal.

Under the heading of miscellaneous observations, the optional 18-way adjustable Adaptive Sports Seats fitted to the test car are brilliant. Comfortable for cruising, they can be dialled up to King Kong levels of grip when required.

A super useful feature is the ability to adjust the passenger seat with the driver's seat controls. So convenient for setting things back to normal after the co-pilot has cranked forward to accommodate a rear seat passenger.

The GT sport steering wheel is just right in terms of its diameter and grippiness and the overhead 'Surround View' function helps when manoeuvring a low and wide-hipped car like this one.

The S4 and S5 range were already an excellent balance between everyday comfort and a genuine sporting edge, and nothing has changed with this update.

I spent time behind the wheel of the S4 Avant and S5 Sportback at their media launch, and both managed to deliver the proper Audi luxury experience over some pretty rough rural roads, while always feeling a bit more sporting than a regular A4 or A5. That’s with the Drive Select left in the default mode, but you can shift that sporting personality up a few notches (while scaling back the comfort), by selecting Dynamic mode. 

My preferred means of adjusting their personality is by simply tugging the transmission selector back to activate S mode, which livens up the engine and transmission without stiffening up the suspension. 

Across the five S4 and S5 bodystyles, there is some variance in performance potential, with the S4 sedan and S5 Coupe topping the performance chart with 0-100km/h boasts of 4.7s, with the S5 Sportback trailing them by 0.1s, the S4 Avant by a further 0.1s and the Cabriolet managing a still-fast 5.1s claim.

Another area I consider the S4 and S5s to get just right is their exhaust note. It is adaptive, but there’s nothing synthetic about it, and the generally muted and distinctly V6 burble is always there to remind you that you’re aboard a proper performance model, but not in such a way that it will annoy you, or your neighbours. Polite performance, if you will.

All S4 and S5 variants boast an impressive array of safety features, but there’s some interesting points when it comes to ANCAP ratings. Only four cylinder A4 models (therefore not S4) were given a maximum five star rating when tested according to less stringent 2015 standards, but all A5 variants (therefore S5) aside from the Cabriolet carry a five star rating based on the tests applied to the A4. So officially, the S4 is not rated, but the S5 Coupe and Sportback are, but based on the A4 rating that doesn’t apply to the S4. As with most convertibles, the Cabriolet is simply not rated. 

The airbag count totals eight in the sedan, Avant and Sportback, with dual front airbags, plus side and curtain airbags covering front and rear.

The Coupe drops the rear side airbags, while the Cabriolet also drops curtain airbags, meaning there’s no airbags for rear seat occupants. The roof is made of folding fabric, there has to be some safety compromise.

Other safety features include front AEB that works up to 85km/h, adaptive cruise control with traffic jam assist, active lane guidance and collision avoidance assist that can automatically swerve, a 360 degree camera system, rear cross-traffic alerts, exit warning that can prevent you opening a door into an oncoming car or cyclist, and pre sense rear that can detect an impending collision from behind and prepare the seatbelts and windows for maximum protection.

Porsche's three-year, unlimited-kilometre warranty is off the pace now, although the paint is covered for the same period, and a 12-year (unlimited km) anti-corrosion warranty is also included.

'Porsche Roadside Assist' provides 24/7 coverage for the life of the warranty, and after the warranty runs out is renewed for 12 months every time the vehicle is serviced at an authorised Porsche dealer.

The main service interval is 12 months/15,000km but no capped-price servicing is available, with final costs determined at the dealer level (in line with variable labour rates by state or territory).

Audi continues to offer a three year, unlimited kilometre warranty, which is in line with BMW but lags behind the five years offered by Mercedes-Benz these days. This also contrasts with the five year norm among mainstream brands, which is punctuated by the seven year warranties of Kia and SsangYong.  

Service intervals are a convenient 12 months/15,000km though, and the same five year ‘Audi Genuine Care Service Plan’ offers capped price servicing for the same $2950 total over five years applies to all S4 and S5 variants. This is only marginally more than the plans offered for regular petrol A4 and A5 variants, so you’re not being stung for the thoroughbred versions.
