What's the difference?
Australia hasn't had what you'd call a love affair with the Porsche Panamera. Especially compared to the on-going romance with its iconic sibling, the 911 and even its SUV stablemates.
The Panamera straddles the fence between high-performance sports car and family sedan and it's a position rivals like the BMW 740i, Maserati Quattroporte and Mercedes-Benz S450 have sometimes found difficult to balance.
This new-generation 'base' Panamera model is on test to see if this sedan's 2025 redesign will launch an arrow from Cupid's bow for Australian families?
The ‘Upper Large SUV over $120K’ segment of the Aussie new-car market is what you might call the top end of town, not only in terms of the extravagant models available but also their purchase prices, which stretch well into six figures and require monthly lease payments that rival home mortgages.
It’s where you’ll find some of the most prestigious marques in the automotive world including Rolls-Royce, Aston Martin, Bentley, Ferrari, Lamborghini, Range Rover, Lexus and BMW. And, of course, Mercedes-Benz with its big GLS which represents the flagship of the German manufacturer’s SUV fleet.
It was given a refresh in 2023 with cosmetic and multimedia upgrades along with powertrain enhancements, but there have only been minor changes since then. We were recently entrusted with the keys to the latest GLS to see if the ‘S-Class of SUVs’ leaves any room for improvement.
The Panamera is the ‘have your Porsche and drive it too’ model.
It encompasses the fun of the 911 while still being a comfortable daily driver that can easily fit a family of four. The cabin is sumptuously styled and not hurting for features, either.
Could the ownership costs and storage be better? Probably, but if you’re looking at this model, those items will probably be lower priorities for you.
For my little family of three, the base model Panamera is a win.
The GLS450d impresses as an entry-level grade, as it’s a more family-friendly allrounder than the specialised AMG and Maybach variants. Its combination of a torque-rich diesel 48V hybrid drivetrain, air-cushioned suspension and plush interior are as well suited to luxury urban travel as they are to grand touring, where its heavy towing and generous load-carrying capabilities can shine. Whether it’s worth around $200K drive-away, only those who shop at the top end of town can decide.
This is more than just a new Panamera - it’s a new generation Panamera.
The outgoing model was sort of a mix between the 911 and Macan but didn’t really hit the mark with any of its borrowed elements.
Beauty is in the eye of the beholder but the redesign sees this model get an outward appearance that looks far more aggressive with a distinct profile that now sets it apart for all of the right reasons.
On the outside, the biggest changes include larger matrix LED headlights and a new front fascia that sits a bit higher with more pronounced curving in the bonnet.
The front gets extra air intakes but there are also larger 'air blade' vents behind the front wheel arches which help smooth the air flow around the wheels and add some extra sculpted sportiness to the car's sides.
The rear has been reshaped to look more like the 911 and isn't as pillowy as the outgoing model. There is a new long LED strip light running the width of the rear and an extra brake light for added dazzlement at night. The rear window now spreads to the width of the liftback lid which makes it appear frameless.
The optioned 21-inch alloy wheels look gorgeous in their painted bronze (or Neodyme) glory and feature the Porsche crest in full colour for added pizzazz. The bronze accent is also carried across to the quad exhausts.
All these factors make the exterior design look more cohesive than the previous model.
The interior has been reworked, too, and the dashboard now sports upgraded tech panels that makes the cabin feel cinematic. The optioned passenger display screen only adds to this effect.
Purists will pout, but like the new 911 the analogue cluster and turn-key operation have died a quiet death. You now get a 12.3-inch digital instrument panel and push-button starter. Plus, the gearshift has been repositioned from the centre console to the dash.
The optioned Sports Chrono and Neodyme accent packages of our test model means the dashboard gets a race clock (superfluous for every day driving but fun to look at) and the door handles, steering wheel and dashboard feature the same bronze highlights.
The only elements that don't look the part are the shiny piano black panels mainly found in the centre console. They're too easily scratched/marked for a car at this price point.
The cabin may not be as flashy as its competitors but it's still sumptuous.
This is an imposing vehicle in extravagant S-Class tradition, riding on an expansive 3135mm wheelbase and stretching more than 5.2 metres (5215mm) long and more than 2.0 metres (2030mm) wide with a turning circle that's nudging 13 metres.
However, it’s just under 1.8 metres (1798mm) tall, so there’s no clearance issues when accessing multi-storey carparks. And with its side-steps (or ‘running boards’ in nostalgic Benz speak) most adults can step rather than climb aboard, although passengers of shorter stature during our test noted that assist handles on the A and B pillars would be handy.
Central to its sophisticated chassis design is adaptive air suspension, which uses a pneumatic or ‘airbag’ form of springing with adaptive damping to continuously optimise ride comfort and handling response according to road conditions and driving dynamics (see Driving).
The GLS’s styling is clean and uncluttered with tasteful restraint evident in its chrome and satin-chrome highlights, yet it projects a majestic quality with its prominent four-louvre grille and elegantly spoked alloy wheels.
The spacious and sumptuous seven-seat interior is visually pleasing and practical, with a subtle blend of surface treatments, contrasting tones, lots of soft-touch surfaces and exposed stitching. This is combined (thankfully) with physical dials, switches and ‘piano key’ buttons to control numerous interior functions, in preference to distracting touchscreen prompts.
The cabin feels spacious in both rows and the rear row can comfortably fit those who are above six foot (182cm) with a caveat.
Despite being optioned with the '4+1' seating, don't be fooled; the middle rear seat is nothing more than extra room for the out-boarders as the rear centre console takes up all legroom a middle seater might need. Not even a kid will be happy in the middle for long.
Amenities in both rows are good. The heating/cooling and massage functions on the front seats are great and the four-zone climate control means everyone can get comfortable.
Access to both rows is surprisingly good with doors that open widely but the rear footwell lip is high and the well narrow. So, if you have clunky boots on you may feel clumsy getting into position.
My seven-year old found the doors heavy to open and it took him a while to realise he didn’t have to slam the doors shut thanks to the soft-close feature.
Individual storage is better than you usually get in a sports car but all cubbies still fall on the shallower side. There are four cupholders, four drink bottle holders, a glove box, a middle console and two small net map pockets. There is also a dedicated phone cubby housing the wireless charging pad.
The boot aperture is wide and it’s super easy to reach things in the back thanks to the liftback lid but that sloping roofline means you lose out on height for larger items.
Stack bigger things right behind the back seat if you want to fit them. Capacity is below average compared to its rivals at 460L.
The rear row has a 40/20/40 split to open up storage options and there is a very deep cubby underneath the floor with the tyre compressor/repair kit.
Device charging options are great with a total of four USB-C ports, a wireless charging pad and three 12-volt sockets to choose from.
The upgraded multimedia system looks fantastic and is user-friendly. The built-in satellite navigation is simple to use and the multimedia system, head-up display and instrument cluster can be highly customised.
The base Panamera model now comes standard with wireless Apple CarPlay and Android Auto. Connecting to the CarPlay is easy and the connection remains seamless.
The optional passenger display panel allows the front passenger to control their climate and seat comfort, see a duplicate of the instrument panel or just watch a movie on a long trip.
The screen has a privacy filter, which means the driver can’t see what’s on it and is thus not a distraction. However, no one in my family bothered to use it.
Although it has a hefty 2655kg kerb weight, our test vehicle’s 3420kg GVM rating provides a useful 765kg of load capacity, which should comfortably absorb the combined weight of up to seven occupants and light luggage. Or with the third row of seating folded, five occupants and heavier luggage.
It’s also rated to tow up to 3500kg of braked trailer and with its sizeable 6920kg GCM (or how much weight it can legally carry and tow at the same time) it can carry its maximum load while towing its maximum trailer weight.
So, that’s commendable practicality, given it would be well suited to owners that need to tow large caravans, boat trailers, horse floats etc in style without having to compromise much (if at all) on either passenger numbers or luggage capacity.
Driver and front passenger space and comfort is exceptional, as you’d expect. Storage includes a large glovebox plus a bottle holder and bin in each door. The front of the centre console has two USB-C ports, wireless phone charging and heated cupholders, while the rear of the console has a large storage box with a third USB-C port and padded lid that doubles as a comfy elbow rest.
Even tall passengers in the second row of seating enjoy spacious comfort, given I’m 186cm and with the driver’s seat set in my position I have ample knee clearance, foot room and head space.
However, the central passenger must contend with a transmission tunnel in the floor and shoulder room would be squeezy for three large adults, which is okay for short trips but a maximum of two would be ideal for longer journeys.
The rear of the centre console also treats second-row passengers to a pair of USB-C ports, adjustable air-vents and a control panel that allows independent climate adjustment.
There’s also a large bin/bottle holder in each door plus storage nets on each front seat backrest. The centre seat backrest folds flat to allow long items (skis etc) to slot between the outer backrests. And it also serves as a fold-down armrest, containing two cupholders and a lidded slimline compartment that’s ideal for hidden phone storage.
The third row is uncommonly spacious, even for tall people, with padded armrests on each side containing cup holders and twin USB-C ports.
The carpeted rear luggage area has four load-anchorage points, a first aid kit and 12v socket. With the third-row seats upright it offers 355 litres of load volume, which increases to 1350 litres with the third row folded and 2400 litres (or 2.4 cubic metres) with both the second and third rows folded.
There are four grades of Panamera on offer for the Australian market and the model on test is the entry-grade sedan, simply titled Panamera.
It feels silly calling a car priced at $236,990, before on-road costs, a 'base' model but here we are.
Our test model has $45,810 worth of optional extras but compared to its rivals the base price positions it towards the middle of the market with the Maserati Quattroporte GT being the most affordable at $219,000, then the Mercedes-Benz S450 at $241,275 and BMW 740i at $272,900. All prices before on-road costs.
As you’d expect, the standard equipment for the Panamera is long-winded and includes matrix LED headlights, four-point DRLs, ambient lighting, four-zone climate control, a dual sunroof, upgraded 12.3-inch touchscreen multimedia system, a new 12.65-inch digital instrument panel, wireless Apple CarPlay/Android Auto and built-in satellite navigation.
Comfort items include 14-way powered front seats with heating/cooling, as well as three-position memory functions. There is also a powered tailgate, front and rear parking sensors, a 360-degree view camera system and soft-close doors with a 'door brake' function.
The latter means the door holds the position you push it out too, minimising the chance of your kids hitting the neighbouring car, which is an awesome feature in a family car!
Other technology includes a total of four USB-C ports, three 12-volt sockets, a wireless charging pad, digital radio, the Porsche app and over-the-air updates.
As for the optioned extras... there is Burmester high-end sound ($11,200), full-grade leather upholstery ($7470), dark bronze accents on the quad exhausts ($6470), 21-inch alloy wheels ($3400), the 'Sport Chrono Package' ($3340), 10.9-inch passenger display screen ($3140), wheels finished in 'Neodyme' bronze ($2500), a massage function on the front seats ($2200), a middle rear seat ($1750), an interior Neodyme accent package ($1190), a heated steering wheel ($1140), an air quality system ($890), an interior black trim package ($760) and comfort pillow accessories ($450). Phew!
Our Polar White test vehicle, which is the base grade in the three-tiered GLS range, comes standard with a 3.0-litre inline six-cylinder turbocharged diesel engine with 48V mild hybrid technology, nine-speed automatic transmission, permanent all-wheel drive and active air suspension for a list price of $189,100.
This pricing is higher than comparative entry-level grades offered by the two marques which dominate sales leadership in this segment, comprising the BMW X7 xDrive40d M Sport ($179,500) and Lexus LX500d AWD ($158,700).
The GLS450d’s standard features include 22-inch AMG alloy wheels with Continental 325/40 R22 tyres and a collapsible spare, ‘AMG Line’ body styling enhancements, aluminium-look illuminated side-steps with non-slip rubber studs, multi-beam LED headlights and more.
Step inside the keyless interior and you’ll find ‘Hey Mercedes’ voice activation, fingerprint scanner (which memorises individual comfort settings for up to seven users), panoramic sunroof, heat-insulating dark-tinted rear privacy glass and the ‘Premium Plus Package’ that includes heating/cooling for the front seats, heated rear seats, head-up display, separate front/rear climate control zones, heated cupholders and more.
There’s also a concert hall-like Burmester surround sound system controlled by a central touchscreen with digital radio and Apple CarPlay and Android Auto connectivity, plus wireless phone charging, multifunction Nappa leather sports steering wheel and USB ports front and rear.
Driver assistance includes the ‘Parking Package’ (360-degree camera, active parking assist and transparent bonnet), ‘Mirror Package’ (auto-dipping rear-view mirror and electric folding door mirrors with puddle lamp projection of the brand logo) and ‘Driver Assistance Package’ (blind-spot assist, exit warning, speed sign recognition, lane keeping etc) all included as standard equipment.
Of course, Mercedes-Benz offers numerous extra-cost options including a 3500kg towing package plus interior, exterior, suspension and wheel enhancements (including Nappa leather trim) for those who want their GLS with the lot, which can easily push the list price beyond $200K.
The base Panamera doesn’t have a hybrid powertrain like its siblings and sports the 2.9L V6 twin-turbo petrol engine of the outgoing model. But it’s been retuned and now produces 260kW and 500Nm – both figures up from the previous model.
The Sport Chrono Package means the 0-100km/h sprint improves from 5.1-seconds to a tummy-sucking 4.8-seconds and my son gave a whoop of delight whenever we had to get up to speed.
The Panamera has an eight-speed, dual-clutch auto transmission and is the only RWD for the Panamera line-up. It also sports a top speed of 272km/h. So, suffice it to say, the engine has the sports cred you expect from a Porsche.
The GLS450d comes standard with a 3.0-litre turbocharged inline six-cylinder diesel producing 270kW of power at 4000rpm and 750Nm of torque between 1350-2800rpm.
This is paired with a 48V mild-hybrid system comprising a 48-volt battery (charged by regenerative braking) and an integrated starter-generator which provides both seamless engine stop-start and up to 15kW/200Nm of extra power and torque during acceleration.
A nine-speed torque converter automatic provides the choice of manual shifting using the steering wheel-mounted paddles, along with several selectable drive modes.
The active all-wheel-drive system continuously adjusts the engine’s torque delivery between front and rear axles (and individual wheels as needed) to maintain optimum traction and handling.
The official combined (urban/extra-urban) fuel-cycle consumption figure is 9.5L/100km, which is pretty low for a high-performance vehicle (and a big one at that) but after a lot of open road and urban driving my real-world usage came out at 10.9L/100km.
That's the result after not being skimpy with using the power, either, so it's not as thirsty as you might expect.
When it comes to times between fills, the Panamera might surprise you. Based on the official combined fuel cycle and large 90L fuel tank, expect a theoretical driving range of up to 947km (825km using our on-test figure) – which is a great driving range for a performance vehicle, let alone a family one.
The Porsche Panamera only drinks the best, so while the driving range is great you won't be able to fill 'er up with anything but premium 98 RON unleaded petrol.
Mercedes-Benz claims official combined consumption of 7.8L/100km and the dash display was showing 9.0 when we stopped to refuel at the completion of our 368km test, which included the usual mix of suburban, city and highway driving with up to five passengers at times and light luggage.
Our own figure, calculated from fuel bowser and tripmeter readings, was close at 9.5 which is outstanding sub-10L/100km economy for such a substantial vehicle in mostly metropolitan use. Therefore, based on our own consumption figure, you could expect a real-world driving range of around 950km from its 90-litre diesel tank.
Some people might not understand the obsession or loyalty Porsche owners have towards their cars but if you’re a fence sitter, get in the Panamera. It will make you understand because after driving one... you'll hear yourself say 'I get it'.
The base model has the goods with the engine outputs to ensure the driving experience remains fun and responsive.
The Panamera is no wild bronco, it's a cool customer. The composure for power delivery is unlike other performance sedans you may have driven. Acceleration is effortless without any twitchiness. You never feel out of control.
The air suspension means you hear the bumps more than you feel them but you still get excellent road feedback as a driver.
Passenger comfort is high, despite the cabin being quite loud with road and engine noise, because the seat and ride comfort remains well-cushioned. Fatigue and jostling are at a minimum.
The handling of the Panamera when it comes to cornering and steering feels dynamic and agile. I made a point of doing multiple mini roadies this week, simply for the joy of driving it.
While the Panamera is the most fun on a winding mountain road, it's a pleasant open-road cruiser as well.
The base Panamera has three driving modes - 'Normal', 'Sport' or 'Sport Plus' with a 20-second power booster available when you need extra oomph.
The Normal mode is sufficient for daily driving and the Sport Plus offers stiffer suspension and handling but the preference is to keep it in Sport mode.
Mainly because in this mode you get an awesome throatiness from the exhaust as well as the dynamics you expect from a sports car.
It’s a bit deceptive but the Panamera is massive and sits at 5052mm long and 2165mm wide - so, it definitely fills out a parking space!
However, the 360-degree view camera system is one of the best in the segment but you may still get choosy with where you park it.
It’s an enjoyable vehicle to drive, with multiple power adjustments for the seat and steering wheel combined with a large left footrest which provide supreme driver comfort and support.
The powerful and responsive turbocharged six-cylinder diesel and nine-speed auto are well suited to this application. The engine’s ample torque provides spirited acceleration from standing starts, taking only six seconds to reach triple-digit speeds.
This drivetrain would be well suited to heavy towing duties, given the 48V mild-hybrid system can contribute an extra 200Nm (in addition to the engine’s 750Nm), which raises the total theoretical torque output to almost 1000Nm.
The active air suspension provides a wonderfully cushioned ride that floats over bumpy roads, while maintaining excellent handling response and surprising agility. These commendable chassis dynamics, combined with the powerful and responsive drivetrain, makes the vehicle feel smaller and lighter than its dimensions and kerb weight would suggest.
Overall, it’s difficult to fault from a driver’s perspective, with the only exception being the voice activation function. This is often triggered by words or phrases other than ‘Hey Mercedes’ resulting in regular interruption of conversations. This needs some fine tuning.
No Porsche is rated with ANCAP and the Panamera is no exception but the base model still has an extensive safety list that includes 10 airbags, which is more than some people movers!
The standard safety kit includes AEB, forward collision warning, blind spot monitoring, driver attention alert, safe exit warning, rear occupant alert, tyre pressure monitoring, an active bonnet and a side impact protection system.
There's also rear cross-traffic alert, lane departure alert, lane keeping aid, a head-up display, adaptive cruise control, a 360-degree view camera system, front and rear parking sensors, park assist, an engine immobiliser and an alarm system with radar-based interior surveillance.
The base Panamera misses out on traffic sign recognition and rear collision warning, though.
The rear row has two ISOFIX mounts and three top tethers but only two seats will be able to fit across the row.
The GLS does not have an ANCAP rating as it’s yet to be tested, but comes standard with a suite of passive and active safety features including nine airbags, auto emergency braking (AEB) with pedestrian detection and junction assist, blind-spot monitoring, traffic sign recognition, head-up display, rear cross-traffic alert, lane-keeping, adaptive cruise control with ‘distance assist’ (autonomously brakes/accelerates in heavy traffic), front/rear parking sensors, 360-degree camera and more.
There’s also two ISOFIX and three top-tether child seat anchorages in the second row, plus two more of each in the third.
Porsche offers the Panamera with a three-year/unlimited km warranty, which is less than its competitors. It's more typical to see a five-year/unlimited km warranty in this segment.
Servicing intervals are reasonable at every 12-months or 15,000km, whichever occurs first and pricing varies per dealership.
The one I contacted (in Sydney) confirmed the first four years of servicing costs $8605 for an average of $2151.25 per workshop visit.
Worth noting the fourth year is a biggie at $4875, this major service including everything from an air-conditioning clean and transmission oil change to spark plug check/replacement and safety checks.
The Panamera is up there for service costs, even for the class but this kind of outlay comes with the territory when you're considering a car worth almost $300K.
The GLS comes with a five-years/unlimited km warranty (better than BMW and Lexus) and five years of roadside assistance. Scheduled servicing is every 12 months/25,000km whichever occurs first.
Mercedes-Benz offers capped-price pre-paid servicing packages with three, four or five-year terms. For example, the total upfront cost of the minimum three-year term is $4090, or an average of $1363 per service.
