Summary
Audi A6
Despite a determined bid for dominance by a growing stream of Q-badged SUVs, with zero-emission Es on the near horizon, Audi’s A-team of mainstream sedans, wagons, coupes, and cabriolets remains vitally important to the company’s product portfolio and bottom line.
But in recent years the Bavarian maker’s mid-size A6 has been hiding in the shadows, unable to lay a glove on its natural enemies, the BMW 5 Series and Merc’s E-Class, in terms of new car sales in Australia.
So, this sizeable piece of fresh metal is designed to push Audi up the leader board. It’s the all-new, fifth generation A6.

BMW 3 Series
Back in the day, the 3 Series sedan was often the entry to the brand for first time BMW owners, and for good reason. They offered practical interior space without compromising on engine performance.
And they simply looked good, no boring nanny design elements. Then the 1 Series came along and price points bumped up, so how does the ‘entry’ BMW 320i M Sport live up to its long-standing reputation?
With an updated dashboard that brings the interior and tech up to market and a sharper exterior design, it more than holds its own at the table of luxury sedans, despite hard competition from the likes of the Audi A4, Mercedes-Benz C200 and Jaguar XE.

However, if the Merc is a placid and well-behaved mare… the BMW is the barely-broken-in bronco and it takes a certain kind of ‘rider’ to enjoy what the 320i has to offer.
I’ve been discovering just that this week with my family of three. What did we find out? Read below!

Verdict
Audi A68.1/10
The new Audi A6 is a composed, rapid, top-shelf luxury sedan. It’s comprehensively equipped, with safety tech a stand-out, and priced to chip away at BMW and Merc’s segment dominance.
But owners in this part of the market tend to be rusted on loyal to their preferred brand, and it will be interesting to see of this impressive newcomer can shake a few of them loose.
Pick of the bunch? Save 10 or $15K or dial down the repayments and go for the entry-level A6 45 TFSI, with all the safety tech on-board, plenty of performance, and most of the luxury features included in the more premium models.
BMW 3 Series8/10
I thoroughly enjoyed my time in the BMW 320i M Sport. It’s fun to drive and I felt connected to what the car was doing on the road. The harder ride may not appeal to some but I didn’t mind it. The cosy back seat and boot mean it will probably suit a smaller family best and one which doesn’t have to worry about carrying a lot of gear around regularly, but it suited my needs just fine.
I reckon this is a car for those drivers who don’t want to compromise on performance but still have a kid or two. If you’re after the cushioned comfort of a Merc, this won’t appeal but I didn't want to give this one back and happily give it a firm 8/10.
My son liked the sports car looks and enjoyed the amenities in his row. He gives it a 10/10.
Design
Audi A68/10
Revealed in Germany in early 2018, the new-gen A6 brings fresh engines, leading edge safety, upgraded media tech, and an evolution of the brand’s distinctive design language.
Always a subjective call, but to my eyes the A6’s exterior, while crisp and contemporary, is evolutionary rather than a game-changing step ahead.
The signature single frame grille is even bigger than before, to the point where it feels like Audi has entered an arms race with the current oversize grille superpower, BMW.
A strongly curved roofline accentuates the car’s steeply raked C-pillars, giving it a close to fastback style. Broad, sweeping surfaces are combined with harder defining edges and creases, while short overhangs accentuate the carefully sculpted, tightly wrapped look.
The A6 45 TFSI rides on 19-inch ‘5-twin-spoke’ design alloys which fill the wheelarches nicely, while the 45 and 55 S line run on similar design 20s.
The S line exterior package incorporates specific front and rear bumpers with honeycomb inserts, side air inlet grilles in ‘matt titanium black’ with inserts in ‘platinum grey’, rear diffuser in the same black, this time with chrome trim, side sill trims, and illuminated aluminium door sill trims with S logo at the front
But the short story is, it looks like a big A4, or a small A8. For some, a very good thing, for others the ‘they all look the same’ syndrome may be a question mark.
The interior is a model of Teutonic restraint, the sleek dash and instrument cluster layout showcasing three digital screens covering instruments, media and other functions as well as heating and ventilation.
Long, horizontal vents are an Audi design favourite, the seats look and feel superb and the entire cabin reeks of quality and attention to detail.
BMW 3 Series
Sharper than its predecessor, the new 320i has LED everything with the rear lights being longer and curving around to the sides of the car.
The classic 'kidney' grille is darkened and more pronounced, with the black panelling extending to the rear to create an unapologetically sporty presence. A presence that’s accentuated by the twin exhausts.
The batcave interior with its black headliner, black seats… black everything, looks smart and stylish.
You do have a fair bit of harder touchpoints throughout but the customisable ambient lighting helps to soften the overall effect.
With its 2068mm width, 4709mm length and 1435mm height, the sedan makes its presence known without feeling cumbersome to manoeuvre. Urban dwellers need not fear their local car park!
Practicality
Audi A68/10
Large rather than huge, the A6’s key dimensions are within mm of its key segment competitors like the 5 Series and E-Class, as well as the Jag XF and Lexus GS.
Room for the driver and front passenger is generous, with ample storage provided including dual (covered) cupholders in the centre console (also incorporating a 12-volt outlet and key holder slot), a decent glove box, and door bins allowing easy bottle storage.
The lidded storage box/armrest between the front seats is relatively shallow but includes a wireless Qi (chee) charging mat (for compatible devices), plus SIM and SD ports, as well as a pair of (Type-A) USB sockets.
The wheelbase has stretched 12mm in this new model, but Audi says it has eked out an extra 21mm of interior length, with 17 of those added to the rear section. And I’m able to sit behind the driver’s seat set for my 183cm position with heaps of head and legroom on offer. Three adults across the rear is definitely do-able for short to medium length trips.
In the rear, a fold-down centre armrest features a lidded storage tray and twin pop-out cupholders (the latter on S line models only). There are netted pockets here and the door bins are big enough for large drink bottles. There’s also climate control ventilation, USB ports, 12-volt power… the lot!
Boot capacity is around the average for the class at 530 litres, and the A6 swallows our three-piece hard suitcase set with masses of room to spare, as it does the jumbo size CarsGuide pram. In fact, it was able to take the largest case as well as the pram at the same time. Drop the 40/20/40 split-folding rear seat to liberate even more volume.
There are pop-up tie-down anchors at each corner of the boot floor, a netted storage cavity behind the passenger side wheel tub, a 12-volt outlet on the driver’s side, a handy fold down shopping bag hook, an elasticised net is included on the S lines, and a space-saver spare sits under the boot floor.
Towing capacity is the same across the range – 2.0 tonnes for a braked trailer, and 750kg unbraked. The spare is a space saver on all models, too.
BMW 3 Series
For such a sleek looking sedan, it’s generous up front with plenty of head and legroom.
You can adjust the seat to sit quite low and both front seats have extendable under-thigh supports, which should excite taller drivers.
My 189cm (6’2”) brother has the 328i and is very comfortable but taller front passengers will encroach on back seat passenger comfort.
The front seats are quite firm on the backside, they also lack adjustable lumbar support, so expect to stretch the kinks out on a longer trip.
The amenities and tech feel well thought out and easy enough to use. The 12.3-inch touchscreen multimedia system looks great and has the best-looking graphics I’ve sampled.
The BMW system is intuitive to use once you get used to it. If you’re not interested in using the touchscreen, you can also utilise the rotary-wheel for menu selections.
There’s also Bluetooth connectivity, wireless Apple CarPlay and Android Auto plus built-in satellite navigation.
The 12.3-inch digital instrument panel is customisable and the information displayed simply but you won’t really look at it because of the head-up display.
Front occupants enjoy a wireless charging pad for their smart phone, a USB-A and USB-C port plus a 12-volt socket. Rear passengers get a couple of USB-C ports, too.
The storage is good for this size sedan but overall passenger room takes priority, but the glove box and middle console will suffice for everyday use.
While it may not excite others, I love the big bottle holders in the doors. They’re large enough for my big 1.5L bottle and angled for easy access. These are found in the rear doors as well.
Back seat passengers enjoy climate control, directional air vents, two cupholders, netted map pockets and reading lights.
My six-year old was happy with the amenities and lower ground clearance because he felt comfortable and had his independence.
The boot offers a good capacity of 480L and the aperture isn’t too narrow, so you can comfortably access items if they roll to the back.
I had plenty of room for my little family’s needs but if you’re a larger family, you may need to get strategic with gear storage.
Being a base model, you do miss out on a powered tailgate, which is a shame but not too much of an issue given this is a sedan and the lid isn’t heavy.
There’s also no spare tyre or even a puncture repair kit but you have run-flats, so you should be able to limp to a service centre if need be.
Price and features
Audi A68/10
The A6 launches with three models, the 2.0-litre, four-cylinder turbo-petrol 45 TFSI at $95,500, before on-road costs, the more premium 45 TFSI S line at $105,200, and the top-shelf 3.0-litre turbo-petrol V6 55 TFSI S line at $116,000.
Included on the A6 45 TFSI are 19-inch alloy wheels, matrix LED headlights with LED DRLs, dynamic cornering lights, automatic-dynamic headlight range control and rear dynamic indicators (the Matrix beam detects and blanks out oncoming vehicles or vehicles in front, but continues to fully illuminate other areas), keyless entry and start including a sensor controlled (leg swish) boot release, electric heated sports seats for the driver and front passenger (including memories for the driver), ‘leather appointed’ seat upholstery, three-zone climate control air, a leather-trimmed steering wheel, ‘aluminium fragment’ interior inlays, ambient lighting, and aluminium front door sill trims.
Plus, ‘Audi Drive Select’ allows the selection of various driving modes, there’s Audi’s smartphone interface providing Apple CarPlay and Android Auto connectivity, ’Qi’ wireless charging, 10-speaker/180-watt audio driven by a six-channel amp and featuring digital radio, the 12.3-inch configurable ‘Audi Virtual Cockpit’ digital instrument cluster, 10.1-inch high-res colour media touchscreen, ‘Navigation Plus’ (with 3D map display including places of interest and city models), and a third 8.6-inch colour display for the climate control system (with handwriting recognition and a favourites list).
The recently introduced ‘myAudi’ app also allows you to connect to the car and access real-time info on everything from how much fuel’s in the tank, to maintenance milestones, and service warnings. You can remotely lock and unlock the car, plan journeys (at home) and send destinations and routes directly to the car.
Then the 45 and 55 TFSI S Line models add ‘Valcona’ leather trim (seat centre panels, seat side bolsters, head restraints and centre armrest, and door trim inserts in Alcantara faux suede), a flat-bottom leather-trimmed sports steering wheel, a head-up display (colour, with speed, nav and assistance info), illuminated front door sill trims, 20-inch alloy wheels, and electronically controlled adaption of the dampers.
BMW 3 Series
There are seven variants for the BMW 3 Series sedan and our model is the base model for the petrol variants.
There is a plug-in hybrid version, the 330e, if you’re after a more fuel-efficient option but it will up the price by about $20K.
As it stands the 320i M Sport is $78,900, before on-road costs. Our model has been finished in 'M Brooklyn Grey', which adds $1539 to the price.
That puts it at a similar price point as its rivals. You get a well-specified package with the M Sport but it doesn’t have the same sense of cushioned comfort as the Merc does, but more on that later.
Still, the sporty and streamlined interior is headlined by BMW’s dual 12.3-inch screens that sit propped on the dash like a futuristic cockpit.
The mix of synthetic leather and cloth seats are electric and have adjustable side bolsters for when you want to go hard in a turn.
The interior also boasts a sunroof and wireless Apple CarPlay and wired Android Auto. There are some other highlights like the 18-inch alloy wheels, leather steering wheel and the crystal-clear head-up display, to name a few.
Under the bonnet
Audi A69/10
The 45 TFSI is powered by a 2.0-litre turbo four, and the 55 TFSI by a 3.0-litre turbo V6, both featuring a mild-hybrid system recovering braking energy to enable coasting at higher speeds and in the latter case power the stop-start system.
The VW Group (EA888) engine used in the A6 45 TFSI is an iron block/alloy head single turbo unit featuring direct-injection and variable valve timing on the inlet side. It produces peak power of 180kW from 5000-6000rpm, and maximum torque of 370Nm from 1600-4500rpm.
The (EA839) engine used in the A6 55 TFSI is a 90-degree 3.0-litre, all-alloy, single (twin-scroll) turbo V6 featuring direct-injection, variable camshaft adjustment (intake and exhaust side) and variable valve timing on the inlet side. It produces 250kW from 5000-6400rpm, and 500Nm between 1370rpm and 4500rpm.
The 55’s 48-volt mild hybrid electrical system recovers regenerative braking energy to power the stop/start system and enable coasting (for up to 40 seconds) between 55-160km/h. It consists of a 10 Ah lithium-ion battery under the boot floor, a water-cooled belt alternator starter (BAS) mounted to the engine’s front end, with a V-belt connecting it to the crankshaft.
As is increasingly the norm with Vee engines from the ‘Big Three’ German brands this one has its single, twin-scroll turbo located in the V6’s ‘hot V’ to shorten gas paths from the exhaust to the turbo, and from the turbo into the inlet side for better throttle response (as in, minimal turbo lag).
Drive goes to all four wheels via the latest gen version of Audi’s quattro system and a seven-speed dual-clutch auto transmission.
BMW 3 Series
The 320i M Sport has the ‘baby’ engine in the 3 Series line-up but the 2.0-litre, four-cylinder turbo-petrol powertrain still delivers on power with a maximum output of 135kW/300Nm.
This is a rear-wheel drive and has an eight-speed auto-transmission which delivers very smooth gear changes.
Despite having the smaller engine, it can still go from 0-100km/h in just 7.4 seconds.
Efficiency
Audi A68/10
Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle hovers all the way from 7.2L/100km for the 45 TFSI, to 7.3L/100km for the 45 TFSI S line, and back to 7.2L/100km for the 55 TFSI S line.
CO2 emissions sit in a similarly narrow band, the 45 TFSI producing 165g/km, the 45 TFSI S line 166g/km, and the 55 TFSI S line 164g/km.
Stop/start is standard on all models, minimum fuel requirement is 95 RON premium unleaded, and you’ll need 73 litres of it to fill the tank (on all models).
The local A6 launch drive program ran to the south of Adelaide in South Australia, with some freeway running followed by the twisting rural B-roads running through the McLaren Vale wine growing area. Spending most time in the 45 TFSI S line (because we’d previously driven the 55 TFSI S line) we saw a real-world average of 9.1L/100km, courtesy of the on-board computer.
In our previous review of the 55 TFSI, over five days of city, suburban and freeway running we recorded a figure of 8.8L/100km. Both numbers impressive for a close to 1.8-tonne luxury sedan.
BMW 3 Series
In a world with rising fuel prices, the efficiency of this decently powered sedan should excite you.
The official combined fuel cycle is 6.5L/100km. Real world testing saw my figure at 7.4L/100km after a mix of open-road and urban driving this week.
I thought that was great for how hard I drove it and for the power, you won’t be wincing when you put your foot down. I would expect it to be higher in an urban setting.
The 320i has a 59L fuel tank and based on the official combined cycle figure, you should get just over 900km of driving range, which is great, especially if you do 'roadies' like me!
Driving
Audi A67/10
Audi claims the 45 will sprint from 0-100km/h in six seconds, and the 55 in just over five. So, quick, and very quick.
Both are super responsive in the mid-range with peak torque available from just 1600rpm in the 45 and less than 1400 in the 55.
As is increasingly the norm with Vee engines from the ‘Big Three’ German brands the 55 TFSI’s single, twin-scroll turbo is located in the V6’s ‘hot V’ to shorten gas paths from the exhaust to the turbo, and from the turbo into the inlet side.
The aim is to sharpen throttle response and deliver power in a smooth, linear flow. And with maximum torque available from so low down in the rev range, that’s exactly the way it feels.
Select Sport mode, squeeze the right-hand pedal, and the 55’s V6 delivers a firm, consistent shove in the back. The 45 is less urgent in terms of acceleration, but more than adequate for easy highway cruising and confident overtaking.
Both are quietly quick, thanks in part to low-noise acoustic glass and comprehensive use of sound absorption materials around the cabin, remaining composed and relatively subdued as speed rises.
The seven-speed dual-clutch delivers ultra-smooth shifts at around-town speeds and crisp, positive changes in manual mode.
In normal, suburban-style conditions the quattro system decouples the rear axle and sticks with front-wheel drive economy. If all-wheel drive is required, a tricky clutch instantly activates it, in certain situations predicatively.
On top of that, in aggressive cornering torque vectoring by braking (Audi calls it ‘Wheel-Selective Torque Control’) retards the near-side wheels before they slip.
Suspension is a five-link set-up front and rear, with much of the hardware made from aluminium to fine tune response and reduce unsprung weight.
Electronically controlled adaptive dampers are standard on the S line models, with the switch between dynamic and comfort settings swift and pronounced.
Rims are 19-inch on the 45 and 20s on the 45 S line and 55 S line, but all variants are comfortable. Never floaty or unwieldy, just refined and well damped.
The electromechanically assisted steering points accurately but the assistance is overdone and road feel isn’t one of the A6’s strongest suits.
Brakes are 375mm ventilated discs at the front, clamped by six-piston alloy calipers, with 350mm rotors at the rear. They inspire confidence, with progressive feel and more than enough to confidently arrest the 1.8-tonne A6's progress.
BMW 3 Series
There's a lot that I like about how this performs but a highlight is how eagerly the car responds when you accelerate.
However, it’s not unbridled power. There’s no bucking at the front or shuddering through the steering wheel. It’s controlled but still very fun.
The lower centre of gravity and coupe-like height of this does mean it handles corners well and the bolstered seats hold you firmly into place, meaning you can be free to drive this a little harder than you might normally. Which I did and can confirm it handles itself well.
This has the M Sport suspension, which means it’s stiff, but you feel very connected to the road.
You do get a lot of talk-back from bumps in the road but unless you hit a big pothole, you never feel rattled by them.
But it is a harder ride than other luxury models, which doesn’t bother me as I like the handling, but if you want limo-like comfort, look elsewhere.
The cabin is very nice to spend a lot of time in and relatively quiet, even at higher speeds.
The 11.4m turning circle and sleek dimensions makes it very handy to park, even in tight car parks. The nose is long but the front and rear parking sensors take out any ‘will I make it’ moments and the super clear reversing camera is great.
Safety
Audi A610/10
Safety is literally five star, the A6 scoring ANCAP’s maximum rating when the car was tested in 2018, and active and passive tech is amazing.
The usual active safety suspects are all present and accounted for, namely ESC (with electronic wheel-selective torque control), ABS, ASR, EDL and ‘Brake Assist’.
But from there the list of standard tech reads like a who’s who of recent innovations, including ‘Adaptive Drive Assist’ (adaptive cruise control with ‘Stop&Go’, distance indicator, traffic jam assist and lane guidance assist), AEB (5.0km/h to 85km/h for pedestrians and cyclists, and up to 250 km/h for vehicles), ‘Collision Avoidance Assist’ (additional steering torque in critical evasive situations), rear cross traffic alert, blind spot warning, and lane departure warning.
The 360-degree camera set-up includes a kerb view function, with four wide-angle cameras covering the entire area immediately around the vehicle for improved visibility during low speed maneuveres.
There’s also an exit warning system (detects vehicles and cyclists when opening doors, triggering a warning light and delaying door opening), ‘Attention Assist’, tyre pressure monitoring, ‘Audi Parking System Plus’ (front and rear with visual display), and ‘Intersection Crossing Assist’.
That last one operates at speeds up to 30km/h, monitoring the area in front and at the side of the car, detecting “oncoming objects” at junctions and exit roads. If the situation is critical the system triggers a visual and acoustic warning as well as a quick jolt on the brakes (at speeds up to 10km/h).
But it’s not over yet, with auto headlights, rain-sensing wipers and ‘Turn Assist’ included. Turn Assist monitors oncoming traffic when you’re turning right at speeds up to 10km/h and applies the brakes if necessary.
If all those measures aren’t enough to avoid an impact passive safety leads off with front airbags for driver and passenger, side airbags for front and rear side passengers, plus curtain airbags covering both rows.
Also included is ‘Audi Pre-Sense Rear’ (tensioning of front seat belts, closing of windows and sunroof and flashing hazards on detection of an impending rear collision), the standard active bonnet helps to minimise pedestrian impact injuries and there’s a first-aid kit as well as a warning triangle and high-vis vests in the boot.
No surprise the new A6 scored a maximum five-star ANCAP rating, the assessment done in 2018 and the score applicable from August 2019 onwards.
BMW 3 Series
The safety list includes a suite of features and the following come as standard: adaptive cruise control, auto emergency braking (operational from 5.0-210km/h), blind-spot monitoring, speed sign recognition, forward collision warning, SOS emergency call button, daytime running lights and rear cross-traffic alert.
I like the intelligent seatbelt reminder and that the bonnet is considered 'active', meaning it will lift up and away from the engine if the sensors detect that a pedestrian has been hit.
However, I have to call out the lane departure and keeping aids. It’s a hit or miss system and I tested it extensively this week once I noticed it.
You can customise the sensitivity levels and even on the highest sensitivity, it works too sporadically for my liking. BMW should improve this system for future instalments.
The 3 Series has been awarded a maximum five-star ANCAP safety rating but it was done a while ago in 2019. It only has seven airbags and is missing the newer front centre airbag.
There are ISOFIX child seat mounts on the outboard seats and three top tether anchor points but the back seat is a bit too narrow to comfortably fit three child seats side by side.
You'll be able to fit a 0-4 rearward facing child seat but may struggle if you're a tall family.
Ownership
Audi A67/10
Audi covers the A6 with a three year/unlimited km warranty, which is in line with BMW and Merc, but lags the mainstream market where five years/unlimited km is the norm, with Kia and SsangYong at seven years.
That said, body cover runs to three years for paint defects and 12 years for corrosion (perforation).
Recommended service interval is 12 months/15,000km, and ‘Audi Genuine Care Service Plans’ offer capped price servicing options over three and five years.
BMW 3 Series
The 320i comes with a five-year/unlimited km warranty, which is standard for this class.
You can choose between a three- or five-year capped-priced servicing plan. The five-year plan costs just $2150, or $430 a year, which is competitive for this class.
Like other BMWs, servicing intervals are condition-based, with the car letting you know when it needs to be serviced.
