What's the difference?
If you want something large, fast and comfortable, no one does it better than the Germans, and the latest entrant to the market is Audi’s all-new S7 Sportback.
Using the uber-stylish second-generation A7 as a basis, the new S7 Sportback scores cutting-edge technology and premium appointments befitting a large luxury sedan, but it’s often what’s under the bonnet that will draw buyers in.
This new S7 replaces the old version’s 4.0-litre twin-turbo V8 for a 2.9-litre twin-turbo petrol V6 but, don’t fear, as having fewer cylinders has not dulled its performance or appeal.
As a whole though, does the new Audi S7 Sportback deliver a winning blow?
Chevrolet’s Corvette Z06 supercar is an all-American answer to European rivals Lamborghini and Ferrari, but it’s not just this that makes it so appealing.
Spending a week with the most potent Corvette you can get in Australia has left me with a list of notes on this beast I want to hand over to you. Maybe it will help make your mind up about it or change your mind.
What makes the Z06 the flagship of the Australian Corvette range isn’t little luxuries, but seriously upgraded mechanical hardware, much of it track focussed.
Our test car was also fitted with the Z07 Performance package which adds a carbon-fibre aero kit to pin the Corvette down at high speed while also drawing everybody’s attention to it.
Oh, and then there’s the sound of the largest flatplane crank V8 ever to go into a production car… and look out for your ankles - let me explain…
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 Chevrolet Corvette Z06 is truly a supercar offering outstanding dynamics for a lot less money being asked by European rivals - just make sure it's not your only car for those times when you're in a hurry.
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.
We’re talking about the closest thing to a real-life Hot Wheels car here. See, while Ferraris look elegant to me like expensive jewellery, Lambourghinis like cheese graters and McLaren’s look like slippery alien spacecraft, the Corvette Z06 looks exactly like an American supercar should - an unapologetic, ludicrous beast. And I love that.
Dialing up the wild is that enormous carbon wing and front splitter with dive planes thanks to the Z07 package. Just a word of warning, though, the front splitter and dive planes stick out not just visually, but in the sense that I walked into them often and my ankles still have the scars.
I can’t recall the last time I drove a car with carbon-fibre wheels either - these are the biggest rims fitted to a Corvette and they’re wrapped in Michelin Pilot Sport Cup 2R ultra performance tyres (275/30ZR20 front and 345/25ZR21 rear) that they look like oil drums on their sides.
The best angle? The rear - straight on. Those headlights.
Wait, no, it’s from above - so you can see the V8 through the glass hatch.
Or it could be front-on looking like a giant shovel..
OK, there are no bad angles..
The Corvette Z06 is long at 4734mm end-to-end, broad at 2024mm wide and its height is a both a sitting-on-the-road-low and numerically pleasing 1234mm.
The plainness of the cabin might be a let down to some people after all the exterior wildness. Ferraris and Lambourghis offer extravagant and exotic interiors, but the Corvette’s innards are almost completely void of flare.
The media screen is small (8.0 inches), switches and controls for windows and air vents are basic, and the huge dividing ‘wall’ between the pilot and passenger might be a bit much for some.
That ‘wall’ is dotted with buttons and while it may look very 'fighter jet cockpit', they’re just climate control switches. Sitting in the passenger seat is a lonely place with no screen visibility nor easy access to controls - I'd actually call this out as a bit of a fail compared to the interiors from Porsche, Audi and Lamborghini with their screen-filled cabins offering co-pilots something to do.
Yes, it feels a bit premium with the Nappa leather and the sports seats, but it could feel more special.
All of this plainness, however, is saved from boredom by the glass window behind the seats allowing you to peer into the engine bay at the V8 like at a reptile enclosure at the zoo.
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.
Supercars don’t tend to be built with practicality as a priority but this two-door, two-seat beastie is spacious enough even for me at 185cm tall with plenty of room in the footwell and loads of elbow-, knee-, and headroom.
Cabin storage is limited to a glove box, door pockets, two cupholders, and a wireless phone charger on the bulkhead behind the seats.
As you can see from the images there’s a boot at the rear which will fit smaller bags and a small boot in the front.
I did the school run in the Corvette a few times (I know, lucky kid) and I can tell you a bass guitar in its case and a school bag, plus my own large handbag make for a cramped cabin. A Kia Carnival the Corvette ain’t, but it’s not trying to be one and compared to its rivals it does well for practicality.
Priced at $159,900 before on-road costs, the new S7 Sportback is about $20,000 cheaper than before.
While the $20,000 saving is nice, we’d argue that maybe the $180,000 pricetag for an S7 was a bit high to begin with.
Aside from the new engine (more on that below), the S7 Sportback comes standard with a laundry list of equipment, including keyless entry, push-button start, 21-inch wheels (available in three designs), adaptive air suspension, privacy glass for the rear, electric tailgate with gesture control, soft-close doors, panoramic sunroof and Matrix LED headlights.
As expected of an Audi, the interior is kitted out with leather and soft-touch materials throughout, but it's equipment such as the illuminated seat belt buckles and loose wheel-nut detection that really elevate it above its peers.
The multimedia system is displayed on a 10.1-inch touchscreen and features satellite navigation with real-time traffic alerts, wireless Apple CarPlay support, Android Auto connectivity, Wi-Fi hot-spotting, wireless smartphone charging and digital radio, while the four-zone climate controls are nestled in the lower 8.6-inch screen.
While we prefer physical buttons to a purely touchscreen set-up, Audi’s implementation is fantastic thanks to the haptic feedback from the screens, which mimic a button press.
We also like that there is a dedicated volume-control knob, meaning you aren’t fumbling around with the touchscreen while driving to turn down the music.
The S7 Sportback also features Audi’s signature 12.3-inch Virtual Cockpit panel, which is still the best application of a digital instrumentation.
We’ve gone into detail about why we love it so much in the past, but a quick recap is that it's super-easy to use, can be customised to show whatever you want to see, and is clear in its layout.
Despite the long list of equipment, there are still a few items left on the options list.
Some, such as ceramic brakes and a Dynamic Package, are aimed to improve performance around the bends, so it’s nice that the extras aimed at a particular type of customer are not bundled into the asking price for everyone.
Likewise, there are also comfort- and style-orientated choices such as carbon interior, DVD player (in 2020?), heated rear seats and a premium sound system, but with the latter costing $11,700, the S7 Sportback’s price can quickly balloon.
Eight exterior colours are also available, each a no-cost choice.
Almost never does a car with a list price of almost $400K get full marks, but here we are and I’ll tell you why. The Corvette Z06 in its standard form lists for $336,000 and this is outstanding value compared to its supercar rivals such as the Ferrari F8 Tributo for $484,888, or a McLaren 750S for $585,800 or even an entry-grade Lamborghini Huracan, the EVO, for $383,187.
Australia gets the top 3LZ trim, with the local standard features list for the Corvette Z06 including Nappa leather upholstery, GT2 bucket seats, a 12-inch digital instrument display, a 14-speaker Bose sound system, red seat belts, wireless phone charging, carbon-fibre and suede microfibre trimmed steering wheel, a media system with sat-nav plus wireless Apple CarsPlay and Android Auto, power seats, heated steering wheel, dual-zone climate control, heated and ventilated seats and a head-up display.
Our test car was fitted with plenty of options including the Z07 Performance Package that brings carbon-fibre everything. We’re talking the enormous carbon-fibre rear wing and aero kit with side skirts and a front splitter with dive planes –and there are the carbon-fibre wheels (20-inch at the front and 21-inch at the rear).
The Z07 package also brings a more hardcore suspension tune and carbon ceramic brakes for ridiculously good stopping power.
The Z06 has the most powerful V8 engine in the Corvette range, too, and we'll get to that soon.
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 5.5-litre naturally aspirated V8 in the Z06 makes 475kW and 595Nm. That’s a lot more power than the Corvette Stingray’s V8, which produces 369kW. The GT3 racecar version of the Z06 uses a derived version of the 5.5-litre V8, and actually it shares 70 per cent of the engineering components.
Revving to a high 8600rpm the Z06’s V8 lets out a high-pitched scream when pushed hard, much like a Ferrari because like many Ferraris the Z06 has a flatplane crank V8 - actually it’s one of the largest flatplane V8s to go into a production car.
Corvettes are now mid-engined cars and the Z06 has an eight-speed dual-clutch transmission that changes gears quicker than I can blink, sending all that mumbo straight to the rear wheels.
Acceleration comes hard, fast and loud with the Z06 able to boot itself from 0-100km/h in 2.9 seconds. That beautifully linear acceleration with no turbos will pull you all the way towards its top speed of 313km/h.
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.
As with practicality, fuel efficiency isn’t the Corvette’s priority and after driving it daily for a week in the suburbs, city and a few dashes out to more open country roads the Z06 was using an average of 23.8L/100km, according to the trip computer.
Luckily the fuel tank is pretty big at 70 litres and with an official combined fuel consumption of just under 16L/100km you have a range of 438km… in theory.
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.
What the Corvette Z06 is like to drive really depends where you drive it. Our suburb has a ridiculous number of speed humps, which are like the Corvette Z06’s Kryptonite thanks to its very limited ground clearance and a carbon front splitter that almost skims the road at the best of times.
This made the Z06 one of the slowest fast cars I’ve ever piloted. My son would beg me to drive him to school in it, but the journey would take twice as long as we slowly eased over each hump while holding our breath. A lift system does raise the front of the vehicle but even then, don't breathe out.
The width and poor visibility made inching down narrow streets of parked cars a stressful exercise, too.
The Corvette Z06 is almost too much of a racecar to live with and then you let it free on an open country road and its purpose is clear - it runs like you wouldn’t believe and screams in delight all the way, while clamping itself to the road with sticky tyres, perfectly set up suspension and proper downforce.
Steering feels mainlined though to your nervous system, the pedals under your feel like your actual feet, and it all feels like a dream until you wake up again when you reach the city limits and round abouts, and traffic and yes, speed humps.
The Corvette Z06 clearly is a car that needs to be joined by other cars in your driveway, ones that don’t even notice speed humps.
Audi’s S7 Sportback was awarded a maximum five-star safety rating by ANCAP based on crash-testing done by Euro NCAP in 2018.
The S7 scored 93 and 85 per cent in the adult- and child-occupant protection tests, while the vulnerable road user and safety assist categories yielded an 81 and 78 per cent score respectively.
Standard safety equipment includes tyre pressure monitoring, autonomous emergency braking, driver attention alert, adaptive cruise control, lane-keep assist, blind-spot monitoring, surround-view monitor, front and rear parking sensors, rear cross-traffic alert and a head-up display.
The AEB system is operational from 10-85km/h according to ANCAP’s documentation, and comes with pedestrian and cyclist detection.
Noticeably absent from the safety list is traffic-sign recognition, though the satellite navigation will give the speed-limit readout based on GPS data.
The S7 Sportback is also fitted with an exit warning system to warn passengers of any incoming cyclists or cars to prevent opening a door into strife.
Along with four airbags, the Corvette Z06 has AEB, forward collision alert, lane-keeping assistance, rear cross-traffic alert, blind-spot monitoring, auto high beam headlights and adaptive cruise control.
An ANCAP safety rating doesn't exist for any member of the Corvette and will likely never due to low volume.
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.
GMSV covers the Corvette with a three-year/100,000km warranty which is short by current standards where carmakers typically offer a duration of five years/unlimited kilometres.
One of the appealing sides to the Corvette is that it’s made by a down-to-Earth American car company and a longer warranty offering peace of mind would seem more appropriate.
Service intervals are every 12 months or 12,000km, with capped-price servicing sadly unavailable.
