What's the difference?
Audi’s flagship is the A8, a long, luxurious sedan where being driven is often as important as doing the driving.
To put this ultra-premium machine in context, it competes with other German heavyweights like BMW’s 7 Series and, of course, the Mercedes-Benz S-Class as well as Porsche’s Panamera. Not to mention the Lexus LS or Maserati’s Quattroporte.
What’s life like at the top of the Audi pyramid? Stay with us to find out.
It’s a good thing the Porsche Panamera doesn’t feel emotions. Otherwise it might be feeling like the forgotten member of the Porsche family.
While the 911 remains the evergreen hero, the Cayenne and Macan the popular sales darlings and the new Taycan the exciting newcomer, the Panamera simply plays its part.
It fills an important but small role for the brand, giving Porsche an executive sedan (and wagon) to compete against the big players from the other German brands - Audi A7 Sportback, BMW 8-Series Gran Coupe and Mercedes-Benz CLS.
However, while it may have been overshadowed of late, that doesn’t mean Porsche has forgotten about it. For 2021 the Panamera has been given a mid-life update, after this current generation launched back in 2017.
The changes are subtle in isolation but add up to some big improvements across the range, most notably extra power has seen the previous range-topper, the Panamera Turbo, become the Turbo S.
There’s also a new hybrid model and tweaks to the air suspension and related systems to improve the handling (but more on that later).
The Audi A8 swims in a luxury car shark tank where those paying the big dollars expect top-shelf everything. It delivers a serene driving experience whether you’re in the front or the back, in a superbly engineered and executed luxury sedan package. Not perfect, but very, very impressive.
While we didn’t get to sample the full breadth of the range, our time in the base Panamera demonstrated that while it’s the most overlooked member of the Porsche family it might also be the most under-rated.
While it may not be the most spacious luxury sedan it does offer ample space and combines it with performance and handling that’s hard to beat. The price drop should help make it a more appealing prospect, although at nearly $200,000 it’s still clearly a premium prospect for a lucky few.
The A8 is close to 5.2 metres long, yet instantly recognisable as an Audi thanks mainly to its evenly weighted proportions, gently curved roofline and overall high-waisted design. Worth noting its drag coefficient (Cd) is an impressively slippery 0.25.
The characteristic look is accentuated by the brand’s signature, six-sided grille, in this instance highlighted by a matrix of high-relief chrome accents. And typically angular LED Matrix headlights sit either side.
Check out our video review for the carefully orchestrated animation they run through when the car is unlocked.
The car looks equally svelte and contemporary from the rear, with just the right amount of chrome lifting the tone and multi-spoke 20-inch rims filling the wheel arches nicely.
As you’d expect, the top-shelf look and feel continues inside with the seats trimmed in aniline leather, perforated on the front and outer rear positions, with genuine hide also covering the centre console, door rails and armrests, steering wheel and upper dashboard.
Fine grain ash wood inserts sit alongside brushed metal elements and a meticulous attention to detail is obvious… everywhere.
For example, the interior door handle design has been thoroughly thought through, requiring a simple underhand tap to open the door, rather than the more conventional, and ergonomically convoluted, ‘over the top’ movement.
Three sleek screens dial up the tech - a 10.1-inch multimedia interface at the top of the centre stack, an 8.6-inch display below it for heating and ventilation, and a 12.3-inch version of Audi’s ‘Virtual Cockpit’ in the instrument binnacle.
And the spacious rear is the epitome of cool, calm Teutonic form and function. You feel relaxed the moment you get in, and isn’t that the primary aim of a car like this?
When the second generation Panamera arrived in 2017 it was widely praised for its design. The new model allowed Porsche’s stylists to tidy up the somewhat puffy design of the original whilst still retaining a clear family link to the 911.
For this mid-life update Porsche has only made some minor nip and tucks rather than a major facelift. The changes centre around the front end, where the 'Sport Design' package that was optional is now standard across the range. It has different air intakes and larger side cooling openings for a more dynamic look.
At the rear there’s a new light strip that runs across the boot lid to connect to the LED tail-lights, creating a more seamless appearance.
The Turbo S also gets a unique front end treatment, to further separate it from the previous Turbo. It gets even larger side air intakes that are connected via a body-coloured horizontal element so it stands out from the rest of the range.
Overall it’s hard to fault Porsche’s decision to not meddle in the design too much. The shape of the Panamera, like a stretched 911 in silhouette, has grown on people over time and the changes they made for the second generation, making it tauter and more athletic in appearance, didn’t need change for the sake of change.
Space is luxury, be it a large house, a first class seat or a spacious car, and at nearly 5.2 metres long with a close to 3.0m wheelbase the Audi A8 measures up.
Even before you get in, the doors have an amazing sense of solidity and quality. It’s like opening and closing a bank vault… if that huge circular door had a power-assisted soft-close function.
There’s copious amounts of space for the driver and front passenger with lots of storage including a lidded box between the front seats, complete with a two-piece longitudinally split top design, so you can sneak your half’s open without displacing your neighbour’s elbow.
The door bins are decent but there isn’t a specific cut-out for bottles, so it’s more a case of laying them down than standing them up. There’s also a handy covered cubby at the end of the door armrests.
The glove box is a good size and there are two cupholders under a pop-up cover in the centre console.
Of course, the back is where space really counts, and there’s as much room as you’d find in, well… a limo.
Sitting behind the driver’s seat, set for my 183cm position, I enjoyed copious amounts of head, shoulder and legroom.
There are electric sunblinds for the rear and rear side windows, controlled by buttons in the door as well as the rear seat remote, a 5.7 inch OLED display housed in the beautifully trimmed fold-down centre armrest (which also has a soft close function!). The remote also allows adjustment of the lighting and climate control. Classy.
There’s a shallow storage box and twin cupholders in the armrest, medium size door bins and hard shell pockets on the front seat backs. The rear armrests also feature a small lidded cubby.
In terms of connectivity and power options there’s wireless Android Auto and Apple CarPlay, a USB-A and USB-C in the front, and an identical pair in the rear, as well as a 12-volt socket in the front and two in the back.
Boot volume is a useful 505 litres (VDA) and the lid is electric, with gesture control. It’s able to easily swallow our three-piece luggage set or the bulky CarsGuide pram. And while the rear seats don’t fold there’s a ski port door to accommodate long items. Just make sure you use the tie-down anchors in the boot to ensure they’re properly secured. There’s a handy netted section behind the left wheel well and a cargo net is included.
Maximum towing capacity, for a braked trailer, is 2.3 tonnes (750kg unbraked) and in more good news, the spare is a space-saver rather than the increasingly prevalent inflator/repair kit.
As the limousine of the Porsche family there’s a big emphasis on space and practicality for the Panamera. But there’s a big difference between a Porsche limo and the rest of the German ‘Big Three’, which is why the Panamera’s closest rivals are the sportier A7/8 Series/CLS and not the bigger A8/7 Series/S-Class.
The Panamera isn’t small, stretching more than 5.0m in length, but because of its 911-inspired sloping roofline rear headroom is compromised. Adults under 180cm (5' 11") will be comfortable but anyone taller may find their heads bumping the roof.
The Panamera is available as both a four- and five-seater, but in a practical sense it would be hard to carry five. The rear middle seat is technically available with a seatbelt but heavily compromised by the rear air-vents and tray that sit on the transmission tunnel and effectively remove anywhere to put your legs.
On the plus side, the outboard rear seats are excellent sports buckets, so they offer great support when the driver exploits the Panamera’s sporty chassis.
This only applies to the standard wheelbase model, the Executive adds 150mm to its wheelbase which primarily helps create some more rear legroom. But we didn’t get a chance to test that for ourselves on this initial launch drive, so we can’t verify Porsche’s claims.
Those in the front get excellent sports seats across the range, offering lateral support whilst still being comfortable.
With an entry price of $202,700, before on-road costs, the A8 is in the thick of it amongst its full-size primo sedan competitors from Europe and Japan. Specifically, BMW’s 740i MHEV ($272,900), the Lexus LS500h ($195,920), Maserati Quattroporte GT ($210,990), Mercedes-Benz S450 ($244,700) and Porsche’s Panamera ($207,800).
By definition, a luxury car should be loaded to the gunwales with features that make life on the road that little bit easier. And aside from the performance and safety tech we’ll cover shortly, the highlights from a very lengthy standard equipment list are - 20-inch alloy rims, metallic paint, adaptive cruise control, digital matrix LED headlights, digital OLED tail-lights, full keyless entry and start, power-assisted door closing, power boot lid (with gesture control), a panoramic sunroof, heated, ventilated and massaging electrically adjustable front seats, heated front armrests and extended leather trim (centre console, door rails and armrests, steering wheel and upper dashboard).
Also included are ambient interior lighting (with 30 colours and six colour profiles), four-zone climate control, electric sunblinds for the rear and rear side windows, ‘Audi Connect’ navigation and multimedia (with voice and handwriting recognition), wireless Android Auto and Apple CarPlay, 17-speaker 730-watt Bang & Olufsen audio (with digital radio) and a colour head-up display.
There’s a lot more, and the A8 can hold its head high in terms of pricing and features relative to its $200K price tag and the competition.
The biggest news in terms of pricing for this updated model is Porsche’s decision to cut the cost of entry - significantly.
The entry-level Panamera now starts at $199,500 (before on-road costs), which is more than $19,000 cheaper than previously. Even the next model up, the Panamera 4 costs less than the previous cheapest model priced from $209,700.
There’s also the Panamera 4 Executive (long wheelbase) and Panamera 4 Sport Turismo (wagon), which are priced at $219,200 and $217,000, respectively.
All four of those models are powered by the same 2.9-litre twin-turbo V6 petrol engine, but as the names imply the standard Panamera is rear-wheel drive only while the Panamera 4 models get all-wheel drive.
Next up is the hybrid range, which combines the 2.9-litre V6 with an electric motor for more performance and greater fuel efficiency.
It starts at $245,900 for the Panamera 4 E-Hybrid, the stretched Panamera 4 E-Hybrid Executive costs $255,400 and the Panamera 4 E-Hybrid Sport Turismo will set you back $253,200.
There’s also a new addition to the hybrid group, the Panamera 4S E-Hybrid, which starts at $292,300, and gains the ‘S’ thanks to its more powerful battery that increases its driving range.
The rest of the extensive line-up includes the Panamera GTS (from $309,500) and Panamera GTS Sport Turismo ($316,800). These are powered by 4.0-litre twin-turbo V8 befitting the role of the GTS as the ‘driver focused’ member of the range.
Then there’s the new range-topper, the Panamera Turbo S, which starts at hefty $409,500 but gets an even more potent version of the 4.0-litre twin-turbo V8.
And, just in case none of those appeal there’s one more to choose from, the Panamera Turbo S E-Hybrid which adds an electric motor to the twin-turbo V8 for the most power and torque in the range. It’s also the most expensive at $420,800.
The Audi A8 50TDI is powered by a 3.0-litre turbo-diesel V6 engine sending 210kW (from 3500-4000rpm) and 600Nm (from 1750-3250rpm) to all four wheels via an eight-speed automatic transmission (with ‘Tiptronic’ sequential manual shift function) and Audi’s quattro constant all-wheel drive system using a self-locking centre differential.
It also features a 48-volt electrical set-up for mild hybrid functionality built around a belt connected starter/generator, AC to DC converter and a 48-volt lithium-ion battery.
With energy recovery of up to 12kW from regenerative braking, it enables the A8 to regularly coast with the engine switched off and helps the extended stop-start system to operate smoothly.
As mentioned earlier there’s a smorgasbord of powertrains for the Panamera range with a variety of V6 turbo, V8 turbo and hybrid variants of both to choose from.
The entry-level model, known simply as Panamera, gets the 2.9-litre twin-turbo V6 making 243kW/450Nm and paired to an eight-speed dual-clutch transmission and sending drive to the rear-wheels.
Step up to the Panamera 4, 4 Executive and 4 Sport Turismo and you get the same engine and transmission but all-wheel drive.
The Panamera 4 E-Hybrid range (which includes Executive and Sport Turismo) has the same 2.9-litre twin-turbo V6 but adds a 100kW electric motor.
That means a combined system output of 340kW/700Nm, driving through the same eight-speed dual-clutch and all-wheel drive system as the non-hybrid variants.
The Panamera 4S E-Hybrid gets an upgraded 17.9kWh battery, replacing the old model’s 14.1kWh version. It also gets a more powerful version of the 2.9-litre V6, tuned to make 324kW, which ups the total output to 412kW/750Nm; again with the eight-speed dual-clutch and all-wheel drive.
The Panamera GTS uses the brand’s 4.0-litre twin-turbo V8 engine, tuned to make 353kW/620Nm, also with the eight-speed ‘box and all-wheel drive.
The Turbo S uses the same engine but it gets a new tune to bump performance to 463kW/820Nm; that’s a 59kW/50Nm increase over the old model’s Turbo, hence Porsche’s justification in adding the ‘S’ to this new version.
And if that’s still not enough grunt, the Panamera Turbo S E-Hybrid adds the 100kW electric motor to the 4.0-litre V8 and the combination produces 515kW/870Nm.
Interestingly, despite the extra power and torque, the Turbo S E-Hybrid isn’t the fastest accelerating Panamera. The lighter Turbo S does the 0-100km/h sprint in 3.1 seconds, while the Hybrid takes 3.2 seconds.
However, the 4S E-Hybrid does manage to out-accelerate the GTS despite using the V6 engine, taking just 3.7 seconds compared to the 3.9 seconds it takes the V8-powered GTS.
But even the entry-level Panamera still does a very rapid 5.6 second 0-100km/h dash, so none of the range can be called slow.
Audi’s official fuel economy number for the combined (ADR 81/02 - urban, extra-urban) cycle is 6.6L/100km, the 3.0-litre turbo-diesel V6 emitting 175g/km of CO2 in the process.
Over a week of city, suburban, and some freeway running we averaged 11.1L/100km, which is acceptable for a 2.1-tonne luxury sedan.
Also worth noting the standard stop-start system works beautifully thanks to the 48-volt starter/generator.
You’ll need 82 litres of diesel to fill the tank and using the official number, that translates to a range of just over 1240km, which drops to around 740km using our real-world figure.
We didn’t get a chance to test all the variants and run the numbers against Porsche’s claims. Again, in an unsurprising development the hugely diverse range of powertrains leads to a wide spread of fuel economy numbers.
The leader of the pack is the 4 E-Hybrid which uses just 2.6 litres per 100km, according to the company, just ahead of the 4S E-Hybrid with a 2.7L/100km claim. Despite all of its performance the Turbo S E-Hybrid still manages to return a claimed 3.2L/100km.
The entry-level Panamera we spent the majority of the time in uses a claimed 9.2L/100km. The Panamera GTS is the least-efficient, with a claimed 11.7L/100km return, which puts it ahead of the Turbo S and its 11.6L/100km figure.
Despite extensive use of aluminium in the ‘ASF’ platform and body panels, the A8 tips the scales at a sturdy 2095kg, yet Audi says the A8 will accelerate from 0-100km/h in just 5.9 seconds. And with 600Nm of peak torque available across a flat plateau from 1750-3250rpm this big four-door gets up and goes hard when asked to.
At more sedate speeds you’re occasionally reminded there’s a diesel engine under the bonnet, with that characteristic engine and exhaust noise only making their presence felt under pressure.
In fact, under normal circumstances, noise, be it the engine, tyres or wind is minimal, thanks to a combination of the car’s aero-efficient shape, thick acoustic glass and other sound-deadening measures throughout the car.
The eight-speed auto transmission is suitably smooth, with the central shifter or wheel-mounted paddles able to make snappy sequential ‘manual’ shifts.
There are four drive modes in the ‘Drive Select’ system - ‘Comfort’, ‘Auto’, ‘Dynamic’ and ‘Individual’ - enabling tweaks to the steering, transmission, throttle and suspension. Comfort felt most appropriate most of the time, although dialling up the throttle and transmission to more aggressive modes in Individual adds an enjoyable edge.
The suspension is five-link front and rear with an adaptive air system smoothing even high-frequency bumps and ruts amazingly well.
Push into a corner and the A8 feels nicely balanced, its wide track, sophisticated suspension, plus the quattro AWD system seamlessly distributing drive between the front and rear axles, keeping the big body under control. In fact, you feel the ‘big car shrinking around you’ syndrome from the get-go.
The steering is precise without being overly sharp and road feel is good. Again, with that 2.1-tonne kerb weight in mind, braking is appropriately powerful with big ventilated discs front (350mm) and rear (330mm).
It pays to remember the turning circle is 12.5m, and it’s worth picking your spot for a U- or three-point turn.
Although there’s a lot going on for the driver in terms of screens, buttons and switches it all makes sense ergonomically. The head-up display is helpful and there’s a common sense mix of digital and physical controls, the latter including an audio volume knob. Yes.
This is where the Panamera really excels. With every vehicle it builds, Porsche works to make it drive as close to a sports car as possible, even if it's an SUV or, in this case, a large, luxury sedan.
Although Porsche has an extensive range, our test drive was primarily focused on the entry-level model. That’s no bad thing as it’s likely to be the biggest seller in the range, but also because it’s an excellent example of a sports sedan done well.
It may be the first rung on the ladder, but the Panamera doesn’t feel like it's basic or missing anything important. The engine is a gem, the chassis is well sorted and the standard equipment level of Australian models is higher than average.
The 2.9-litre V6 twin-turbo makes a nice noise, a melodious V6 burble, and delivers plenty of punch when needed. Even though it tips the scales at more than 1800kg the V6 with its 450Nm of torque helps punch it out of corners with intent.
The corners is where the Panamera really shines. Even by the highest sports sedan standards the Panamera is a class-leader thanks to all of Porsche’s decades of know-how being poured into its development.
Point the Panamera at a bend and the nose responds with the kind of precision you expect from a sports car.
The steering provides accuracy and loads of feedback, so you can place the car accurately despite its size.
You do notice its size and weight as you get into the middle of the corner, but that’s no different from any of its rivals as you can’t fight physics. But for a luxury sports sedan, the Panamera is a star.
To add another layer to its appeal, the Panamera rides with excellent poise and comfort despite its sporting nature.
Often sports sedans tend to focus too much on handling and stiffer suspension settings at the expense of ride comfort, but Porsche has managed to strike a great balance between the two seemingly opposing characteristics.
Even though the A8 hasn't been assessed by ANCAP, as you might expect, it goes to town when it comes to active safety tech, the car’s standard crash-avoidance features including auto emergency braking (AEB) (pedestrians/cyclists - 5.0-85km/h, vehicles - to 250km/h), ‘Active Lane Assist’, blind-spot monitoring, a reversing camera and 360-degree view (including kerb view function), front and rear parking sensors, ‘Collision Avoidance Assist’ (steering assistance in critical situations), ‘Turn Assist’ (monitors incoming traffic when turning right), and rear cross-traffic alert.
There’s also ‘Intersection Crossing Assist’, ‘Attention Assist’, tyre-pressure monitoring and an ‘Exit Warning System’ (detects cars and cyclists when opening doors).
If all that isn’t enough to avoid a crash the airbag count runs to nine, including front and side bags for the driver and front passenger, side airbags covering the outer rear passengers, full length curtains and a front centre airbag to minimise head clash injuries in a side impact. A first aid kit, warning triangle and high visibility vests are also on-board.
There are three top tethers for baby capsules/child seats across the back seat with ISOFIX anchors on the outer positions.
ANCAP hasn’t tested the Panamera, most likely due to the substantial costs involved with crashing half a dozen sports sedans but its limited market probably factors in too, so there’s no crash test score.
Autonomous emergency braking is standard, as part of what the brand calls its ‘Warn and Brake Assist’ system. It can not only detect potential collisions with cars, using the forward camera, but also mitigates against cyclists and pedestrians.
Porsche has included plenty of other standard safety features including 'Lane Keeping Assist', adaptive cruise control, 'Park Assist' with surround view cameras and a head-up display.
Notably, Porsche doesn’t offer its mild-autonomous functionality, 'Traffic Jam Assist', as standard; instead it’s an $830 option across the range.
Another significant safety optional extra is night vision - or 'Night View Assist', as Porsche calls it - which will add $5370 to the cost.
The A8 is covered by Audi Australia’s five-year/unlimited km warranty, which is now par for the luxury market course, and 24-hour roadside assistance is included for the duration.
Paint defects are also covered for five years, with rust (to the point of perforation) covered for 12. Nice.
Service is required every 12 months or 15,000km with a five-year capped-price plan for the A8 coming in at $3830, or $766 per year. That’s a fair wedge but not outrageous for the category.
Service intervals are annually or every 15,000km (whichever comes first) for routine oil changes, with every second year a more significant inspection.
Prices vary state-to-state due to different labour costs, but as an indication Victorian residents pay $695 for the annual oil change, while the inspection costs $995.
There are other notable charges you should factor in, including brake fluid every two years for $270, while every four years you need to change spark plugs, transmission oil and air filters which add up to an extra $2129, on top of the $995.
The Panamera is covered by Porsche’s typical three-year warranty/unlimited kilometre, which used to be the industry standard but is increasingly becoming less typical.
