Audi A7 vs Infiniti QX30

What's the difference?

The Audi A7 is a really likeable car, one that is heavily focused on style but also emanates substance. The 55 TFSI model will appeal to many, but my initial impression is that the best buy in the range could well be the entry-level 45 TFSI. I can't wait to sample it sometime in 2019.

Even though it’s almost identical to the Q30, the QX30 manages to feel sufficiently different in suspension tune and cabin ambiance to be considered different.

It’s a disappointing oversight, though, by Infiniti to deny the base GT such basic safety fundamentals as a rear view camera (which Infiniti assures us is being worked on).

If you can't find something interesting about the design of the Audi A7, there's a good chance you're visually impaired.

The original A7 Sportback was perhaps ahead of its time in the way it blended the lines of a coupe with the practicality of a big sedan, and the new second-generation version pushes the envelope even further into the future. The vision, according to chief designer Andreas Koglin, was "a clear form with sharp lines and tight shapes", including the distinguishable 'boat tail' at the rear.

This is a technologically advanced looking car - big, long, sleek and stylish. From the LED headlights (or matrix LED and laser lights - yes, frikkin' lasers that have the same 5500 Kelvin as the sun, according to Audi) and daytime running lights, to the long, lean LED tail-light assembly, there's an illuminated, enlightened air to the A7.

Plus, with the matrix lights, both ends of the car do a sort of disco sequence as part of the start up and shut down procedure for the car.

There are a few carefully balanced lines across the body of the A7 that help catch the light, which is something you can't really say about its closest direct rival, the Mercedes-Benz CLS. It still retains the 'big-metal-small-glasshouse' look of the existing model, but there are definitely more angles and interesting elements to this new-generation car.

There are two exterior types offered for Australia - the S line that you see here is the version that'll be fitted to the two higher grade models, while the entry-grade model gets a less aggressive look to its front and rear bumpers. To my eyes, the base car actually looks more luxurious, where the S line models - when not fitted with the optional black exterior styling pack that deletes the chrome trims outside - have a slightly uneasy look in the grille area. With a black edge to the single frame grille, it looks a touch more convincing.

The A7 is still large, at 4969mm long (-5mm) and riding on a longer 2926mm wheelbase (+12mm), spans 1908mm wide (2118mm including mirrors), but it's also a little bit taller, at 1422mm (+2mm). According to Audi, the interior space has been increased by 21mm in this generation, making for a more luxurious cabin than before.

Things are a little edgier in terms of design in the cockpit, too. Gone is the appealing wraparound dashboard design, with a more driver-focused treatment evident. It looks sharper, more shapely, and has improvements to the usability inside, too.

The QX30 is one of the first projects to result from a technology partnership formed between the parent company of Mercedes-Benz and the Nissan-Renault Alliance.

In a sign of how worldly the car industry is becoming, the QX30 is built in Nissan’s Sunderland plant in the UK, using the German Mercedes-Benz A-Class platform and powertrains, all under Sino-French ownership via the Nissan-Renault Alliance.

On the outside, the design that first aired on the Q30 is pretty unique. It’s not a subtle car, with deep crease lines along its sides that, according to Infiniti, is an industry first in terms of manufacturing complexity.

When it comes to differences between the two vehicles, it’s minimal at best. There is a 35mm increase in height (30mm from taller springs and 5mm from roof rails), an extra 10mm in width, and extra trims affixed to the front and rear bumpers. Aside from the all-wheel-drive underpinnings, that is pretty much it for the exterior.

The same black plastic overfenders that are fitted to the Q30 are present on the QX30, with 18-inch rims on both the base model GT and the other variant, the Premium.

The dimensions of the QX30 are also an exact match for those on the Mercedes-Benz GLA, with the long front overhang acting as the main visual connection between the two cars.

According to Audi, the A7's interior is said to offer a "futuristic lounge type ambience". And if your vision of a lounge in the future includes beautiful textile finishes, quality trims, and your choice of three crisp screens to look at and interact with, it certainly lives up to that.

Unlike the existing model, which seemed to draw a bit more inspiration from the world of watercraft, the new model isn't as luxe looking, with a more tech-focused approach inside. The wraparound finish on the dash is gone, and everything is more driver-centric in its orientation - the screens are tilted just enough towards the pilot and the design of the dashboard helps anchor the person in the driver's seat as the most important in the car.

As a driver, I still struggle to come to terms with climate controls that require you to use a screen, and I think it's distracting, too. At least with the Audi screen there's the possibility to slide up or down on the temperature display to make quick changes, rather than having to tap the screen repeatedly.

The haptic feedback on the screens is something that does take a bit of getting used to, because the response time isn't as instant as some regular touchscreen systems, but the menus are all pretty logically laid out.

And of course, all the storage considerations are dealt with, including good cupholders between the seats, decent door pockets, some loose item caddies and so on. In the back there's a flip-down armrest with cupholders, bottle holders in the doors and map pockets on the seat backs. One really neat addition is illuminated seat belt buckles - clever!

Space back there is mostly good, but it's better if you're short. There's enough legroom and shoulder-room for three adults, but anyone taller than me (I'm 182cm) will likely lack some headroom due to the curvaceous roofline.

The boot is good at 535 litres - enough to deal with two golf bags, the brand claims. The shape of the boot means tall items mightn't fit, but the length and width is good, and you get tie-downs with a mesh net to keep things in order. And there's a space-saver spare wheel under the boot floor.

The QX30 is obviously very similar to the Q30 in many respects, but the interior is slightly different, with larger, less cosseting seats up front and slightly higher seats in the rear.

The cabin is also lighter in overall appearance, thanks to a paler colour palette.

There are plenty of neat inclusions, including a pair of USB ports, plenty of door storage, a space for six bottles and a sizable glove box.

A pair of cupholders resides up front, along with a pair in the fold-down armrest in the rear.

There is no particularly logical location for the storage of smartphones, though, and the lack of Apple CarPlay or Android Auto is down to Infiniti opting for its own phone connectivity suite.

A decent 430 litres of luggage space behind the rear seats is contrasted by a cramped rear area for all but the smallest of passengers, while sharply shaped rear door apertures making getting in and out a bit of an ask.

There are two ISOFIX baby seat points and a 12-volt socket in the rear, as well.

The QX30 will be offered in two variants; the base model GT at $48,900 plus on-road costs, while the Premium will cost $56,900.

Both come equipped with the same engine; a 2.0-litre four-cylinder turbocharged petrol engine that’s sourced from Mercedes-Benz and also used on the Q30 and Merc GLA.

Eighteen-inch rims are standard on both cars, while an electronic handbrake, 10-speaker Bose audio, 7.0-inch multimedia screen and a full set of LED lamps all round are fitted across both variants as well.

Unfortunately, the QX30 GT misses out on a reversing camera all together, a fate it shares with the Q30 GT. 

Infiniti Cars Australia told us that this was an oversight at the time the cars were being specced for Australia, particularly in light of the other technologies that the car would receive, like automatic emergency braking.

The company says it’s working hard to bring a reversing camera to the GT.

The top-spec Premium gets leather trim, a powered driver’s seat, and additional safety equipment like a 360-degree camera and radar cruise with brake assist.

The only optional extra on each car is metallic paint.

All three drivetrains offered in the A7 have some form of mild hybridisation. The entry-level 45 TFSI engine is a 2.0-litre four-cylinder turbo producing 180kW of power (at 5000-6000rpm) and 370Nm of torque (1600-4500rpm). It has a 0-100km/h claim of 6.8 seconds, and employs a seven-speed dual-clutch auto with quattro all-wheel drive. It employs a 12-volt mild-hybrid system to assist with stop-start traffic and uses brake regeneration, too.

The high-spec petrol is the 55 TFSI, a 3.0-litre V6 producing 250kW (at 5000-6400rpm) and 500Nm (1370-4500rpm). The 0-100 claim is 5.3sec, and it also uses a seven-speed dual-clutch auto. It has a 48-volt mild-hybrid system that uses a larger capacity battery and a belt-driven starter generator that recuperates energy in stop start traffic and, according to Audi, can also allow the car to coast for up to 40 seconds at speeds of 55-160km/h.

The same 48-volt tech is used for the only diesel model in the range, the 50 TDI. This powertrain uses a 3.0-litre turbo-diesel engine producing 210kW (3500-4000rpm) and 620Nm (2250-3000rpm), and unlike the petrols, it has an eight-speed automatic (not a dual-clutch). The claim for acceleration is 5.7sec from 0-100km/h.

Just the one engine is used across both cars; the 155kW/350Nm single-turbo 2.0-litre four-cylinder petrol engine from the Q30 and A-Class.

It’s backed by a seven-speed transmission and wired into an all-wheel-drive system that is biased towards a front-drive configuration.

Sourced from Mercedes-Benz, up to 50 per cent of drive can be sent to the rear wheels, according to Infiniti.

The mild hybrid tech in each of the A7 models help it offer miserly fuel consumption.

The 45 TFSI model claims 7.1 litres per 100 kilometres; the 55 TFSI model just a touch more, at 7.3L/100km. And as you might expect, the 50 TDI diesel model is the most efficient, using a claimed 6.0L/100km.

We only drove the 55 TFSI on test, and the dashboard indicated display of 9.1L/100km seemed pretty respectable.

Infiniti claims a combined fuel economy figure of 8.9L/100km for the 1576kg QX30 across both the variants; this is 0.5L thirstier than the Q30 version.

Our brief test yielded a dash figure of 11.2L/100km over 150km.

A lot of the time when we go on new car launches the test drive route is planned to highlight handling dynamism, with less focus on the day-to-day drudgery most of us will actually encounter.

The launch of the Audi A7 was primarily of that design, too, but (thankfully?) there was some disgusting traffic to deal with on our in and out of Brisbane, where it was clear the A7 is superbly comfortable.

Well, that is, if you get the air suspension system. The ride was impressively cushioned, untroubled by sharp edges and road joins, and the suspension eliminated pothole effects, too. All the cars I drove on the launch were the 55 TFSI model, and all had the air suspension - the cynic in me thinks there's probably a reason for that, and I'd love to sample one without it.

This stint of stop-start driving saw the engine cut out at speeds up to 22km/h when you're decelerating, allowing us to coast to a stop without the engine burning fuel.

Once we exited the city limits and found ourselves on the roads of Mt Nebo and Mt Glorious, the chance presented itself to push the A7 in some bendy bits. With the dynamic drive mode selected, the transmission in sport mode, and about a hundred corners to contend with, the big German luxury hatch showed its skills.

The air suspension kept the circa-1815kg model relatively flat in the bends, but the front seats lacked adequate side bolster support despite being called 'sports' seats. Obviously physics were at play here.

The steering was more eager in the four-wheel steer version we sampled, and that's definitely an option for the enthusiastic owner to consider. Otherwise, the steering was accurate, if devoid of meaningful feel.

And while the engine was strong in its response and the transmission clever in its shift speed and intelligence, it became clear that this was a car that seemed more adept at open road cruising than bruising a series of hairpins. It didn't disappoint in terms of dynamics - it just felt its size.

Eventually when we reached an open road, the effortlessness of the A7 came to the fore. Comfort mode engaged, it paced along beautifully, the adaptive cruise taking its surroundings in nicely. There is a touch of wind noise and the suspension can be loud when you encounter pockmarked sections, but it doesn't feel flustered at speed.

One of the nice elements of the A7's smarts is that it will pulse the accelerator pedal to warn you that you could be saving fuel - say you're approaching an 80km/h zone, and you're driving at 100km/h, the throttle will throb to let you know you could ease off. Neat.

At the end of our day of driving, I was left with the impression that the Audi A7 is more than capable as a luxury saloon, one that was relaxing to drive - even when we encountered a five km traffic jam on the way back into Brisbane. It feels well engineered, without excessive gimmickry and with enough genuine quality to leave you feeling pampered.

Again, it would be easy to think that the QX30 would feel almost identical to its lower-riding sibling – but that would be incorrect. We criticised the Q30 for being a bit too buttoned down and unresponsive, but the QX30 feels more lively and involving, thanks to its unique spring and damper set-up.

Even though it’s 30mm higher than the Q, the QX doesn’t feel it at all, with a benign, pleasant ride with good body roll control and competent steering.

Our front-seat passenger complained of feeling a little ‘hemmed in’, which is a valid point. The sides of the car are very high, and the roofline is quite low, exacerbated by the steeply raked windscreen.

The 2.0-litre four-potter is smooth and punchy, and the gearbox well suited to it, but it’s lacking in aural character. Luckily the QX30 does a terrific job of suppressing noise before it gets into the cabin, then…

The QX30 gets seven airbags, auto emergency braking, forward collision warning and a pop-up bonnet as standard across the line.

The base GT does, however, miss out on a reversing camera.

The Premium model also offers a 360-degree camera, blind spot warning, radar cruise control and brake assist, traffic sign detection, reverse motion detection and lane departure warning.

As with all Audi models, there's a three-year/unlimited kilometre warranty offered. Mainstream brands seem to be pushing to five years' warranty, while the premium makers lag behind.

The company also offers a three-year pre-purchase capped price service plan called the 'Audi Genuine Care Service Plan', which you can bundle into your finance package. Exact pricing isn't known yet, but you can expect it to average out at about $650 for every 12 month/15,000km service (based on the previous generation model).

The Q30 is offered with a four-year, 100,000km warranty, and servicing is suggested every 12 months or 25,000km.

Infiniti offers a fixed three-year service schedule, with the GT and the Premium both costing an average of $541 over the three services provided.
