Audi S7 vs Audi A5

What's the difference?

Audi’s S7 Sportback wraps style, comfort and sportiness in an appealing package that is sure to please onlookers and occupants alike.

The great engine/transmission aside, the S7 Sportback also has cutting-edge technology at a more affordable pricetag, though less-than-comfortable rear-seat space lets it down a little.

We wish the car we sampled didn’t have the all-wheel steering, as we much preferred the more neutral feel of the S6 sedan we also drove but, overall, the S7 Sportback puts forward a strong case for its existence.

Predictably stylish, predictably competent, predictably comfortable. In fact, that predictability is among its only downsides. In short, the updated A5 might not move the needle all that much, but it didn't need much moving in the first place. 

Audi’s second-generation A7 has always been a bit of a looker, but Audi has taken it up another notch in the S7 Sportback.

Differentiating the S7 Sportback is a more aggressive bodykit, complete with larger air intakes up front, blacked out exterior trim, quad-exhaust tips (denoting that it’s an Audi Sport model) and large 21-inch wheels

The S7 doesn’t go too overboard with the aggressive appointments however (that’s what the top-spec RS7 Sportback, due here later this year, is for), but balances its sportiness with a stately aesthetic.

We think the S7 Sportback is stunning, especially the white exterior colour that gives it an almost Stormtrooper-like look, but even our test car, finished in Daytona Grey, while much more subtle, is still easy on the eyes.

We especially like the strong shoulder line, chiselled doors and sloping roofline of the Sportback body style that combine in profile to make the S7 look like a sprinter on the starting blocks ready to pounce.

Inside, the S7 Sportback scores all of Audi’s latest interior technology, including a 12.3-inch Virtual Cockpit instrumentation and dual-screen centre console layout.

The triple screen set-up definitely helps the S7 Sportback feel very cutting-edge from the driver’s seat, especially when you start to play around with the multimedia system that sports haptic feedback when you press the screen.

Everything is laid out in a clear, concise and easy-to-use manner, while the surfaces of the dashboard are covered in soft-touch, premium materials.

If we’re being honest, we'd probably skip the red-leather interior of our test car in favour of something a little more subdued, but to each their own.

We like the integrated air-vents that blend well into the dash, while the sea of black is broken up with some aluminium detailing and different finishes.

It's gorgeous, the A5. There's simply no disputing it. It's elegant, sophisticated, and above all, restrained. There's no look-at-me chintz here, just clean lines, sharp creases and a shapely figure.

Like its A4 sibling, the A5 has been tickled at the front, with a new-look grille, along with a new headlight cluster with redesigned DRLs, and Matrix LED headlights. 

The four sharp bonnet creases that fan out from the grille lend the A5 a sense of speed, even when stationary, and we love the way the 19-inch alloys fill the wheel arches. It looks polished, premium and athletic. 

Inside, Audi's interior treatment is on-point, from the figure-hugging leather seats to the material choices that span the dash. The big news in the cabin is the inclusion of Audi's new 10.1-inch touchscreen perched above the dash, which isn't just easier to use (in my opinion, at least), but also removes the traditional controls from the centre console. 

It means Audi's already fuss-free cabin is even less cluttered, and it's definitely a change for the better. 

Measuring 4969mm long, 1908mm wide, 1417mm tall and with a 2928mm wheeblase, the S7 Sportback falls well and truly into the large car class.

Up front, the driver and passenger have plenty of room, while the seats and steering wheel are almost infinitely adjustable to find the perfect position.

As you can imagine though, the sloping roofline does eat into the rear-seat headroom a little.

The outboard seats offer plenty of leg- and shoulder-room, but the slanted roof prevents my six-foot-tall frame from sitting up straight comfortably.

Don’t get me wrong, the space is perfectly useable for children or even some smaller adults, but don’t expect to get any basketball players in those seats.

As for the middle seat, only children will find it comfortable due to the protruding transmission tunnel and higher-set seat.

The S7 Sportback’s boot offers at least 535 litres of space and expands to 1380L with the 40:20:40 split-fold rear seats stowed.

Being a liftback (or Sportback in Audi parlance) means the boot is much more practical than a standard sedan, and with such a large aperture, bigger items such as suitcases or golf clubs won’t be annoying to load and unload.

Bag hooks, storage tie-down points and carbo netting also feature to ensure your goods don’t roll around when the S7 Sportback is in motion.

Storage around the cabin though, could be a little better as the wireless smartphone charger takes up a fair chunk of room in the shallow central storage bin under the front armrest.

The usual storage tray found ahead of the shifter is also absent, due to the dual-screen centre console layout, but two generous cupholders and sizeable door pockets are still available up front.

Second-row passengers get access to a fold-down armrest with shallow storage tray and cupholders, as well as door pockets that can accommodate large bottles.

It very much depends on the model you've opted for, with the Coupe compromising backseat space for exterior style. 

The Sportback is easily the most practical of the trio, what with its four doors, comfortable backseat and dimensions that stretch 4757mm in length, 1843mm in width and 1386mm in height, and its 480 litres of boot space.

The Coupe, then, is a two-door design, stretching 4697mm x 1846mm x 1371mm, with 450 litres of luggage space at the rear. It's long, the Coupe, but most of that space is absorbed by the front half of the cabin, wth the backseat reserved for kids. 

Finally, the Cabriolet (which we're yet to test) stretches 4697mm x 1846mm x 1384mm, and will deliver the lowest luggage capacity of the lot, at 375 litres.

Elsewhere, though, the A5 range delivers two cupholders up front, with another two in the centre armrest that can deploy to divide the rear seat. Rear-seat riders also get air vents with their own temp controls, USB charge points (joining the two up front) and bottle holders in the doors. 

For parents, you'll find a pair of ISOFIX attachment points in the backseat, too. 

The cheapest way into an A5 remains the Sportback or Coupe body styles, which will set you back $71,900 with the 40 TFSI engine choice. You can upgrade to the 45 TFSI quattro engine, but doing so will also up the entry point to $79,900. The Audi A5 Cabriolet sits atop the pile, costing $85,400 for the 40 TFSI, and $93,400 for the 45 TFSI quattro.

Happily, all A5s get the S line style treatment, gifting each a sportier look, with a new-look grille and venting adding to the performance-spec style up front. 

You also get 19-inch alloys, Audi drive select with five drive modes, three-zone climate (and neck-level heating in the Cabriolet), leather trim, matrix LED headlights, as well as tech-heavy interior highlighted by a new 10.1-inch touchscreen in the centre of the dash that controls the cars key audio, navigation and driving settings. 

Speaking of the Cabriolet, the three-layer acoustic roof opens in just 15 seconds at speeds of up to 50km/h, with a wind deflector also deployed to help with cabin ambience.

Audi's very cool Virtual Cockpit (a 12.3-inch digital display that replaces the traditional driver's binnacle) is also standard, as is Apple CarPlay and Android Auto. Audi says the new model offers 10x the computing power of the outgoing model, owing mostly to connected car features including live traffic, weather reports and fuel pricing, as well as the ability to remote unlock or lock you car from your phone, or pre-plan destinations and send them to the vehicle's nav.

Powering the new S7 Sportback is a 2.9-litre twin-turbocharged petrol V6, punching out 331kW/600Nm, which is paired to an eight-speed automatic transmission that sends drive to the road via Audi’s quattro all-wheel-drive system.

The result is a zero-to-100km/h acceleration time of 4.6 seconds.

Keen-eyed Audi fans might note that those are the exact same engine and outputs as the RS5 Sportback, RS5 Coupe and RS4 Avant, and they’d be right, however, Audi has added the 48-volt mild-hybrid and an electric powered compressor (EPC) to reduce turbo lag in the S7 Sportback.

It’s a similar system first employed in the SQ7 large SUV, and basically means that the EPC is spooling up the turbo at low engine speeds for better off-the-line performance.

The mild-hybrid technology no doubt helps shift the S7 Sportback’s 2040kg weight with peak power now available earlier on in the rev range (from 5700rpm), while maximum torque is available from 1900rpm.

Compared to the older car, the new S7 Sportback matches its predecessor in power, but ups torque by 50Nm despite losing the old car’s 4.0-litre twin-turbo V8 engine.

Two choices here, the slightly tongue-twisting 40 TFSI and  and 45 TFSI quattro, both of which make use of a 2.0-litre turbo engine tuned for different outputs. 

The 40 will serve up 140kW and 320Nm, and pairs with a seven-speed S tronic automatic that shuffles that power to the front wheels. Audi reckons you'll see 100km/h in as little as 7.3 seconds.

The 45, on the other hand, will give you 183kW and 370Nm, pairing with the same auto gearbox, but this time sending power to all four wheels thanks to the quattro system. The 100km/h sprint drops to 5.8 seconds at its fastest.

Official fuel economy figures for the S7 Sportback are 8.5 litres per 100km, but in our brief time with the car we managed 13.6L/100km, mainly due to the inner-city and country B-road driving.

The 48-volt mild-hybrid system works to reduce fuel usage, by as much as 0.4L/100km according to Audi, and allows the car to coast with the engine off between speeds of 55km/h and 160km/h for up to 40 seconds.

The start/stop system also aids in reducing fuel usage.

Audi reckons the 40 TFSI engine will return 6.5L/100km on the combined cycle, and emit 148g/km of C02. The bigger engine increases fuel use to 7.1L/100km, but lowers the C02 output to 163g/km. Both those fuel numbers are taken from the Sportback.

Both engines also get a new 12V mild-hybrid system said to drop fuel use by up to 0.3L/100km.

Fun tank capacity is either 54 litres or 58 litres, depending on the model.

Audi’s formula for a go-fast vehicle has always been simple – quattro all-wheel-drive for grip, potent engine for speed – and the new S7 Sportback remains true to that formula.

We are big fans of the 2.9-lite twin-turbo V6 engine, which is matched wonderfully with a smooth-shifting eight-speed automatic transmission.

The S7 Sportback always seems to have plenty to give no matter where you are in the rev range, and the transmission isn’t bogged down with slow gear changes up or down.

Though it’s hard to tell how much the EPC helps in getting the S7 up to speed, if you have you window down and accelerate hard from a standstill, you can hear the electronics whirring away.

The standard air suspension also does a wonderful job at absorbing road imperfections in comfort, while it can be switched over to dynamic for a more sporting characteristic.

Grip is plentiful thanks to 255/35 tyres and the quattro all-wheel-drive system but, as with other Audis, the S7 Sportback tends towards understeer when pushed hard around a corner.

Being such a long and wide model, you definitely feel the S7 Sportback’s size on the road, especially when navigating through quick direction changes, but this is where the $7700 Dynamic Package comes into play.

It adds a sports differential, variable ratio steering and all-wheel steering, all aimed at sharpening the S7 up in the bends.

Our test car was fitted with the option pack, but it left us a little cold.

The all-wheel steering especially, made the S7 Sportback’s handling feel too artificial for our tastes, and we were never able to gauge where the rear end wanted to go in a corner.

If we were buying one, we’d leave the Dynamic Package option box unticked.

Bringing the S7 Sportback to a stop are big 400/350mm brake rotors front/rear, with six-piston callipers in the front.

Ceramic brakes with grey-painted callipers can be optioned for $18,000, but the standard stoppers do a fine job scrubbing speed in the S7 Sportback.

You'd describe the A5's drive experience as evolved, rather than revolutionary, but to be honest, in a vehicle this competent, that's no small thing. 

The hybrid tech is unnoticeable, and so the A5 delivers an on-the-road feel that isn't far away at all from the car it replaces. None are truly fire-breathing, but it feels comfortable and sophisticated, the outside world largely banished from the interior (though the firm-ish ride can send road imperfections into the cabin).

Audi has done a stellar job of making the A5 feel connected to the road below it, and the world around it, without dialling down the comfort factor. The steering, light in its normal setting but firming up as you cycle through the drive modes, is direct, but not twitchy, the ride is firm, but not uncomfortable, the engine (at least, the 45 TFSI we drove on launch) is capable without being ridiculous. 

The end result is a predictably competent drive experience, with the A5 delivering in the areas it should, largely before you even notice. 

The only downside to all of that, though, is that the experience is so predictable, that there are few surprises, positive or negative, thrown in. It can leave you feeling slightly disconnected from the experience, rather than truly engaged.

Now, a disclaimer, we spent limited time in the A5 on launch, so we'll wait until we get it in the CarsGuide garage before making a final verdict. But I'd be surprised if we liked it any less over a longer period.

Standard safety kit includes eight airbags, parking sensors front and rear, a 360-degree parking camera, adaptive cruise control with stop-and-go, rear cross-traffic alert, exit warning, and lane keep assist and lane change assist, along with a bevy of airbags, with the A5 range still wearing a five-star ANCAP safety rating.

Like all new Audi models, the S7 Sportback comes with a three-year/unlimited kilometre warranty with three years roadside assist.

Audi’s warranty still lags behind Mercedes-Benz and Genesis, two premium marques that offer a five-year/unlimited kilometre warranty on their models.

Scheduled service intervals are every 15,000km/12 months, whichever comes first.

A three- or five-year service plan is available for the S7 Sportback, priced at $2350 and $4110 respectively.

All Audi's are covered by a three-year, unlimited-kilometre warranty, with servicing required every 12 months or 15,000km.

You can pre-pay your service costs for three or five years, which will set you back $1800 for three years or $2820 for five years.
