Audi A7 vs BMW X3

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.

This is a highly competent all-rounder, given that it has the comfort and practicality for urban family duties yet with its revered M breeding can produce a level of performance which, in competent hands, could hold its own at a track day where its capabilities could be safely explored.

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 fourth-gen X3, which has a lighter but stiffer body, shares the same wheelbase as its third-gen predecessor but at 4755mm end-to-end it's 34mm longer and it's 29mm wider.

It’s also 25mm lower, which combined with front and rear track-width increases and adaptive suspension damping to sharpen the handling underlines its sportiness and driver appeal, despite a substantial 2055kg kerb weight.

The new exterior design is characterised by short overhangs, flush door handles, a larger ‘split kidney’ grille, new LED taillights and L-shaped light elements for the LED headlights.

The new interior design is a classy mix of soft-touch materials and high-gloss hard surfaces in tastefully contrasting tones. The seats are upholstered in a new synthetic leather called 'Veganza' ('Espresso Brown' in our example) which according to BMW requires 85 per cent fewer CO2 emissions to produce than genuine leather (which is still available as an extra-cost option).

Combined with subtle use of ‘Magnolia’ fine-wood trim inserts, satin chrome, piano black, blue/red M highlights and slender ambient light-strips, it’s a cabin that exudes opulence.

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.

This would make a great family weekend escape machine, for which BMW quotes a 645kg payload rating. It’s also rated to tow up to 2500kg of braked trailer, which could pose a challenge given the relatively low 100kg tow-ball download limit (TBD is typically around 10 per cent of trailer weight).

BMW also does not publish a GCM figure (how much it can legally carry and tow at the same time) so we can’t confirm if it can carry its maximum payload while towing its maximum trailer weight.

Even so, the M50 has a useful-sized luggage area which offers up to 570 litres (or 0.57 cubic metres) of load volume with the rear seat upright.

This expands to 1700 litres (or 1.7 cubic metres) with the rear seat folded flat, which can be handy for a multitude of tasks like transporting a mountain bike or hauling home flat-pack furniture.

There’s comfortable space for the driver and front passenger, along with useful storage including large bottle-holders and bins in each front door.

The centre console has two small-bottle/cupholders plus wireless phone-charging and a pair of USB ports. There's also a glove box plus another box at the rear of the console with a padded lid that doubles as an elbow rest.

The rear bench seat is surprisingly spacious, given that I’m 186cm tall and when seated behind the driver’s seat in my position I still have about 40mm of knee clearance, which is optimised by the concave shape of the front seat backrests.

The spacious and airy feel is enhanced by the ‘panorama’ glass roof which spans the full length of the seating area and allows generous headroom even for tall people.  

However, shoulder room is tight for three adults and the centre passenger’s feet must contend with the transmission tunnel, so even though it would be fine for three kids we’d suggest a limit of two adults for longer trips.

Rear passengers get privacy glass and pull-up roller sunshades, large-bottle holders and bins in each door plus net-type pockets and anchorage points for media devices on each front seat backrest. There are also two small-bottle/cupholders in the fold-down centre armrest.

The rear of the centre console has two USB ports, adjustable air-vents plus controls for zone temperature, airflow preferences and seat-heating.

The bench seat features a 40/20/40 split, which allows the centre backrest to fold forward independent of the two outer backrests to allow long loads like snow skis, home hardware etc to be carried if securely fastened.

A power tailgate provides access to the luggage area, which is equipped with a handy 12-volt accessory socket plus load-anchorage points front and rear, extra storage nooks for small items on either side and a retractable roller-type load cover. Overall, this vehicle offers good practicality for family duties.

Our X3 M50 xDrive test vehicle, finished in new 'Dune Grey Metallic', comes standard with a 3.0-litre turbocharged inline six-cylinder petrol engine incorporating 48-volt mild-hybrid technology, plus an eight-speed automatic and permanent all-wheel drive for a list price of $128,900.

You’d expect a high performance prestige vehicle costing six figures would be packed with desirable standard features and the M50 xDrive delivers, starting with big 21-inch 'M' lightweight alloy wheels shod with wide 285/35R21 tyres.

However, there’s no room for a spare (not even a space-saver) so you get a tyre repair kit instead.

The standard equipment list also includes adaptive LED headlights (with matrix high-beam and blue design detailing), a power tailgate, an ‘Iconic Glow’ illuminated kidney grille with M-specific elements, quad exhaust outlets, a panorama full-length (fixed) glass roof, a choice of six premium metallic paint colours and more. The 'M Sport Pro' visual enhancement package is also included.

Step inside and the driver is treated to a head-up display and an elegantly curved digital dash display, which spans about two-thirds of the cabin's width. It seamlessly incorporates a 12.3-inch driver’s instrument display (made from recycled polyester) and 14.9-inch multimedia display controlled by BMW’s latest 'iDrive System 9' software.

Premium audio is provided by a 15-speaker 750-watt Harman Kardon surround sound system, which includes digital radio and wireless Apple/Android connectivity. There’s also wireless phone charging.

The driver gets a thick leather-rimmed and heated 'M Sport' flat-bottom steering wheel and the driver and front passenger are also treated to sumptuous bucket seats with multiple power adjustments and heating/cooling.

Up to three passengers can share the rear bench seat and indulge in the luxury of three-zone automatic climate control, heating for the outer seating positions, privacy glass, roll-up sunshades, two USB-C ports and lots more.

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.

According to BMW, the M50 xDrive features the most powerful inline six-cylinder petrol engine fitted to an M Performance model.

This 3.0-litre unit clearly benefits from BMW’s twin-scroll turbocharging technology, which combined with variable valve timing and an extra 13kW/200Nm from the 48V mild-hybrid technology produces a stomping 293kW of power at 5500rpm and 580Nm of torque at 1900rpm.

It also has a ‘boost’ function, which provides an extra burst of power for short periods when maximum acceleration is required when overtaking etc.

It’s activated by the left paddle-shifter on the steering wheel and automatically optimises transmission/chassis settings to suit. There’s also a drive mode selector, with ‘Sport’ offering the most responsive and engaging experience.

The eight-speed torque converter automatic is a refined and efficient transmission well suited to this full-time all-wheel drive application. Rapid-fire manual shifting is also available using the steering wheel paddles.

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.

BMW claims an official average combined consumption of 8.2L/100km but the dash display was showing 9.9 at the completion of our 210km test, which included a mix of suburban, city and highway travel.

Our own figure, calculated from fuel bowser and tripmeter readings, came in slightly higher again at 10.5L/100km, which given our test vehicle’s two-tonne-plus weight and performance capabilities is still reasonable economy.

So, based on our figures, you could expect a realistic driving range of around 600km from its 65-litre tank, which prefers premium 98 RON petrol.

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.

First, the fun stuff. It certainly feels like ‘the ultimate driving machine’ when you slide behind the chunky leather-rimmed flat-bottom steering wheel and hold it in your hands.

The driver’s seat offers not only powered adjustment of backrest and base-cushion rake, but also four-way lumbar support and side-bolsters that can tighten their embrace of your upper torso to contend with high cornering loads.

There’s also manual extension of the base-cushion length for greater thigh support and a big left footrest to brace against, so you could not ask for a more accommodating and purposeful driving position.

The steering is perfectly weighted and the quartet of enormous disc brakes provide ample bite with superb pedal feel. Combined with its adaptive suspension and wide grippy tyres, the X3 is a family car that’s also invigorating to drive, particularly when you select the ‘Sport’ mode.

The enhanced engine response and sharper steering that result (even the instrument panel display changes) make any twisting mountain road an engaging experience, enhanced by an intoxicating exhaust note that only a BMW M six can deliver.

The turbocharged engine offers an unyielding surge of acceleration from well below peak torque at 1900rpm to maximum power at 5500rpm, making BMW’s claim of 0-100km/h in a scant 4.6 seconds sound credible.

You can also manually change gears using the steering wheel paddles, but we found the gearing and shift calibrations so good that we preferred to leave it in auto mode.

However, the X3 M50 has two distinct personalities, as in more relaxed drive modes it’s just as happy serving as practical family transport during the week for grocery shopping, daily school runs and other common tasks.

It’s also a comfortable tourer for family getaways, with long gearing that requires only 1500rpm to cruise at 100km/h where low engine, tyre and wind noise allow highway conversations at lounge room levels.

No ANCAP rating as yet but this X3 comes with a long menu of standard safety features including multiple airbags, AEB with pedestrian/cyclist/junction detection, front collision warning with brake intervention, lane-keeping, active cruise control, head-up display with speed sign recognition, front and rear cross-traffic alert, tyre pressure monitoring and lots more.

There are also ISOFIX and top tethers for the two outer rear seating positions.

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).

It comes standard with a five-year, unlimited km warranty.

Scheduled servicing is determined by BMW’s vehicle monitoring system which advises when a service is needed, typically around 12 months/15,000km.

A capped-price servicing package covering five years/80,000km (whichever occurs first) totals $2475, or an average of $495 per service.
