Audi S7 vs Peugeot 408

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.

The Peugeot 408 GT plug-in hybrid features tech that could be improved upon and like all plug-ins, you get the best economy if you regularly charge it and that’s not always realistic. It is a little expensive compared to its rivals but sports a killer design that looks fresh and the cabin is roomy with nice features.

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.

There’s quite a lot happening with the design because of the mash-up of body styles. The long sleek body has sedan vibes but it sits high enough to tag itself as an SUV and the rear has that classic coupe pinching.

It won’t be everyone’s cup of tea but I like it. It's bold and different, which feels like a bit of fresh air in this SUV-heavy market.

The lights also set this apart from its Peugeot stablemates and look more refined, too. You can still see the remnants of the original ‘claw’ design in the tail-lights if you look closely but it's the long vertical DRLs at the front that give the design real edge. They resemble the fangs of a snarling cat (just too cool).

The sophisticated sleekness is extended to the interior where you find a cabin that is flush with high-end materials and soft touch points.

The curved dashboard, high-end tech screens and the mix of Nappa leather upholstery and synthetic leather trims definitely cement its grade position. While not a fan of the green contrast stitching myself, it does create an interesting focal point.

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.

Both rows have ample leg- and headroom for my 168cm height. Even my father, who is 183cm tall, felt comfortable in both rows.

The seats are comfortable and offer enough padding to be enjoyable on a long trip. The heat and massage functions on the front seats make the cabin experience feel refined but the massage function sometimes stops when the heat function is also on.

Individual storage is good for the class with the front getting some centre console storage spots, including a phone shelf, as well as a dual-opening middle console, glovebox and two cupholders. There are also a small storage bin and drink bottle holder in each door.

In the rear, there are directional air vents, two USB-C ports, map pockets and a drink bottle holder in each door but you miss out on cup holders, an armrest and other items you might expect for this grade level, like heated outboard seats or climate control.

The other charging options are solid with the front row getting two USB-C ports, a wireless charging pad and a 12-volt socket. There is another 12-volt socket in the boot.

The 10-inch touchscreen multimedia system looks great and you can customise your ‘buttons panel’ to the features you use most often, which is very clever. However, the system isn’t always responsive which gets very annoying - the seat functions in particular can be laggy.

The system does feature built-in satellite navigation and wireless Apple CarPlay and Android Auto but the multimedia system is too glitchy to truly charm.

The boot features a tyre puncture repair kit, relatively level loading space and 471L of boot capacity, which has been fine for all of my errands this week. You also get a hands-free powered tailgate, which is always handy.

The 408 is being offered in one grade for the Australian market, the GT model, and it’s priced from $67,990 before on road costs, making it more expensive than its rivals.

The closest rival, the Cupra Formentor VZe PHEV sits at $64,990 MSRP and the Citroen C5 X PHEV slides in as the most affordable at $57,670 MSRP.

However, only being offered in one grade does have its benefits because the GT is highly specified and most people will be satisfied with the long features list.

In terms of luxuries, there is a heated steering wheel, powered front seats with heat and massage functions, with Nappa leather upholstery and synthetic leather trims throughout.

The technology looks gorgeous with a 10-inch touchscreen multimedia system and a 10-inch digital instrument cluster headlining the dashboard. It's rounded out by the wireless Apple CarPlay and Android Auto, built-in satellite navigation, four USB-C ports, two 12-volt sockets and a wireless charging pad.

The key practical features include a powered tailgate, dual-zone air-conditioning, push-button start, keyless entry and the front driver's seat features a two-position memory function.

You can option a panoramic sunroof for an extra $2000, if you want it.

The 408 only comes in five colours, with the Obsession Blue on our test model being the only included colour. The rest are priced at $690 but the Elixir Red jumps up to $1050.

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.

The 408 GT is a front-wheel drive that has an eight-speed auto transmission and is powered by a 1.6-litre turbo-petrol engine and an 81kW electric motor, which produce combined outputs of 165kW/360Nm. It can do a 0-100km/h sprint in 7.8 seconds. 

The switch between the electric and petrol components isn’t always seamless and you can feel some shudders as it flips between them at lower speeds but the power feels adequate for everyday driving.

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.

The official combined cycle fuel consumption figure is 1.5L/100km but that’s if you were recharging the car every time the electric range dropped out.

My real-world consumption sat at 5.5L after a mix of open-road and urban driving. I only charge it every other day as that’s realistic for my family life but like all plug-ins - you will get the best efficiency if you charge it regularly.

The 408 GT has a Type 2 charging port and a small 12.4kWh lithium-ion battery that can accept up to 3.7kW of power. You get up to 60km of pure electric driving range (but I only saw a top of 38km available) and on a domestic socket, you can go from zero to 100 per cent in around six hours.

On a 7kW or 11kW AC power charger, that drops to three and a half hours. So, it’s a tad slow to charge but worth it if you can leave your car on charge overnight.

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.

The 408 GT has more than enough power to be a comfortable open-roader. You can keep your speed consistent on hills and it has enough gumption to cross traffic quickly in an urban environment.

Steering is responsive and the car is easy to manoeuvre in close quarters but the lane-keeping aid does severe corrections, so have your wits about you when you’re on the go because it can be a fright when the wheel starts fighting you.

With the ride comfort, there can be vibrations through the seats and steering wheel depending on the road surface and you’ll know about it when you hit a bump. It’s okay enough to not be classed as rough but it’s not as refined as you'd hope.

Despite the narrow rear window, the visibility is actually very good and it’s easy enough to park but the 180-degree camera system needs work.

You'll end up using the straight reversing camera because you need to ‘drive’ over the space for an image to pop up for the '180-degree' view and by the time it does, you’ve parked anyway!

The 408 is so new that it doesn’t have an ANCAP safety rating but it has a long list of safety features that it might not worry you.

That list includes all of the biggies like rear cross-traffic alert, blind-spot monitoring, forward collision warning and AEB.

It also includes a driver attention alert, dusk-sensing auto lights, tyre pressure monitoring, lane departure and keeping aids, traffic sign recognition, intelligent seatbelt warning and adaptive cruise control.

Parking is sorted with the 180-degree view camera system and front and rear parking sensors.

The 408 only features six airbags, which is low, and is missing out on the newer front centre airbag and even a drivers knee airbag.

For any families out there, the rear features ISOFIX child-seat mounts on the outboard seats and three top-tether anchor points. Two seats will fit best, though.

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.

The 408 comes with a usual warranty term of five-years/unlimited km and the battery is covered by an eight-year or up to 160,000km warranty.

You can pre-purchase three, four, or five-years worth of services, which all work out to be cheaper than the pay-as-you-go option. It costs $1200 (three-years), $1700 (four-years), and $2000 for the five-year plan.

On the five-year plan, services average $400, which is reasonable for the class. Servicing intervals are also good at every 12 months/15,000km, whichever occurs first.
