Summary
Mercedes-Benz CLS-Class
There are people who probably wish the Mercedes-Benz CLS would just go away. Call security, have it escorted off the premises. That’s probably because they don’t agree with its styling. For them, it’s not how a large four-door Mercedes-Benz should look, with its ‘rude’ coupe roofline.
But for some of you those looks are exactly why you want it, and there’s enough of you out there for Mercedes-Benz to tell us at the launch of the new-generation CLS that the model is here to stay.
“You don’t surrender a segment… a vehicle has to do 100 units to justify bringing it – this will do 100 units no problem sat all,” were the exact words from Benz’s head of communications David McCarthy.
You could say Benz created the four-door coupe segment when it launched its first-generation CLS 14 years ago, triggering its rivals to fire back with their own four-door coupes - the Audi A7 and BMW 6 Series Gran Coupe.
Far from surrendering, the CLS has evolved again with this third-generation bringing new engines and styling. So, what do you gain and what will you have to surrender (for lack of a better word) if you choose to go down the non-traditional route of the CLS?
I found out when I drove the new CLS 450 4Matic for the first time on Australian roads at its recent launch.

Porsche Panamera
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?

Verdict
Mercedes-Benz CLS-Class8/10
The Mercedes-Benz CLS has proven to be a niche hero, creating a segment and then evolving into something even more elegant, while keeping its unique appeal. A beautiful, modern cabin and the new engine in the CLS 450 provides the swiftness to match those looks.
Do you wish the Mercedes-Benz CLS would just go away or do you think it's just perfect? Tell us what you think in the comments below.
Also, check out Matt Campbell's video review from the CLS's international launch:
Porsche Panamera8.4/10
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.
Design
Mercedes-Benz CLS-Class9/10
The new-generation CLS has arrived looking slipperier than a cake of soap on the bottom of the bath. This model has always had svelte styling, but things have become even smoother with Benz’s design chief Gorden Wagener insisting more lines be removed in the creation of this latest version.
So, while there’s the familiar profile of that roof tapering down into the boot lid, the long rear overhang and that sliver of a window opening arching and turning down sharply at the rear, it's a more flowing design now that there are less edges to break it all up.
A new ‘shark nose’ grille opening, and broad bonnet adds a hunk of muscle car toughness to the CLS’s face. But it’s refined thuggery, with that single-louvered ‘diamond studded’ grille flanked by flush-mounted headlights. The tail-lights, too, are so contoured to the body around them they look painted on.
As CarsGuide senior editor Matt Campbell pointed out in his review of the CLS at the international launch, the car looks far better in the metal than it does in any photo.
The CLS is based on the E-Class, sharing its platform and technology, but it’s about 20mm longer (at 4988mm) end-to-end. That’s almost 50mm longer than the previous generation CLS, too. At just over 1.4m tall the CLS is low-slung but wide at 1.9m across (almost 2.1m including mirrors).
The CLS’s cabin mirrors that of the E-Class, too, with a sweeping dashboard which flows through into the doors, two large landscape displays for your instruments and media, an oversupply of air vents and some darn sexy lighting. It’s a luxurious, stylish, comfortable, but snug setting cocooned by padded leather and polished surfaces.
The Australian CLS has been fitted standard with the AMG interior and exterior packages.
You can pick from 11 colours – eight of which are no-cost options and include, 'Polar White', 'Obsidian Black', 'Iridium Silver', 'Citrine Brown', 'Graphite Grey' and 'Cavansite Blue'. Optional colours include 'Hyacinth Red' and 'Selenite Grey Magno'.
Porsche Panamera
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.
Practicality
Mercedes-Benz CLS-Class7/10
Remember how I said you were going to have to surrender something if you wanted a CLS? Well, yes, you’ve have to surrender your hard-earned money, but you’ll also have to give up quite a bit of practicality.
That swooping roofline makes entry into the front seats a bit precarious for people of my height (191cm) trying to swing themselves into the cockpit without clocking their heads on the A-pillar.
The impracticality only gets worse with entry into the back seats, and legroom in there for me is tight, too.
I can only just sit behind my driving position thanks to the contoured seat backs. Headroom is also limited.
It’s worth pointing out that this time the CLS is a five-seater – the previous generation sat just four.
Storage isn’t bad, running to a deep centre console bin with a split lid, there are two cupholders up front and another two in the rear fold-down armrest along with another covered drawer, and all doors have small bottle holders.
The CLS’s boot capacity is 520 litres, and the rear seats fold 40/20/40 to provide extra space.
Porsche Panamera
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.
Price and features
Mercedes-Benz CLS-Class8/10
Benz has dropped the 250d grade, which means you can no longer have your CLS with a diesel engine. That also means the new entry fee is higher with the CLS 350 kicking the line-up off at $136,900 (list price).
You’ll be rewarded with a decent amount of equipment for the outlay, though. Coming standard on the CLS 350 are those two 12.3-inch screens, a head-up display, a 13-speaker Burmester stereo, sat nav, Apple CarPlay and Android Auto, digital radio, surround view camera, leather upholstery, heated front seats, 'Brown Ash' wood trim on the centre console, wheel-mounted shifting paddles, AMG exterior and interior packages, auto-parking, 20-inch AMG wheels, air suspension, proximity key and privacy glass.
The CLS 450 4Matic lists for $155,529 and adds air filtering in the cabin, power closing doors, a sports exhaust system and all-wheel drive.
At the top of the three-grade range is the Mercedes-AMG CLS 53 4Matic+ for $179,529. The extra money buys you nappa leather upholstery, wireless charging, the ‘Night’ body kit, an AMG exhaust system, and of course, a lot more grunt which you can read about below.
Porsche Panamera
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!
Under the bonnet
Mercedes-Benz CLS-Class8/10
If you’ve skipped straight to this bit you’ll have missed news that there’s no longer a diesel engine in the CLS line-up. Instead you have a choice of three petrol engines – one for each grade and all of them are new to the model.
The CLS 350 has a 2.0-litre four-cylinder turbo-petrol engine producing 220kW/400Nm. That grunt is delivered to the rear wheels via a nine-speed automatic.
The CLS 450 4Matic has a 270kW/500Nm 3.0-litre in-line six-cylinder engine with a twin-scroll turbo and like the Mercedes-AMG 53 above it has an integrated electric motor called an EQ Boost. While it’s a hybrid system of sorts the electric motor doesn’t drive the wheels, instead it recuperates kinetic energy and charges the battery.
The CLS 450 uses the nine-speed auto, as well, and is all-wheel drive.
The Mercedes-AMG CLS 53 4Matic has the same transmission and engine as the CLS450 but has been given a heftier twin-scroll turbo charging system and tuned to produce even more grunt at 320kW/520Nm. The 'EQ Boost' performs the same function as in the CLS 450, but also provides power to an electric turbocharger. The Mercedes-AMG CLS 53 4Matic is also all-wheel drive and uses a nine-speed automatic.
Porsche Panamera
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.
Efficiency
Mercedes-Benz CLS-Class8/10
This is a good place to remind you (again) that only one CLS grade was available to drive at the Australian launch – the CLS 450, and we were only given the claimed fuel economy figures for that model.
After 197km through, on a route that bumper to bumpered its way out of Melbourne CBD and headed the long way to the airport via Woodend. our car’s trip computer was reporting close to an average of 10.0L/100km.
Porsche Panamera
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.
Driving
Mercedes-Benz CLS-Class8/10
A reminder again, folks – Mercedes-Benz only had the CLS 450 available to drive. Okay? On with the review…
Nobody likes a traffic jam, apart from maybe taxi drivers. But sitting in a CLS deep in Melbourne’s CBD, stuck in road-work-infested roads, choked with cars going nowhere was as pleasant as the experience could be.
Plush seats, pretty lighting, air filtered and fragranced, air suspension cushioning the patchy tarmac underneath as we wriggled our way north towards Mount Macedon and country roads.
If you read another review calling out a large degree of wind noise filtering into the cabin, they’re right and wrong. See, the weather was apocalyptic as we hit the motorway. Trees doubled over kind of windy, and sure you could hear it rushing past the windows when we were at 110km/h, but you could also hear it clearly when we were at 30km/h.
I like gadgets and so it was about 15 seconds into the motorway stint that I tested out the active cruise control, and automatic lane changing, which works near perfectly.
As the roads became more winding, I switched drive modes to 'Sport', firming up the suspension and steering, at the same time prompting the transmission to kick back into a lower gear.
This is a stable-feeling car, well balanced and effortless to steer. Smoothness is a word for everything it does, including covering the ground quickly.
While that acceleration is rapid, it’s not quite exhilarating, and the engine note under load is a little high pitched for a thug like this.
CLSs of the past were known for being a bit more aggressive and feistier, but this one seems to have mellowed in its third generation. I don’t see any issues with this. There are other angrier Benzs if that’s your thing.
Porsche Panamera
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.
Safety
Mercedes-Benz CLS-Class9/10
The second generation CLS was never crash tested and this new one has yet to be as well. So, while it hasn’t been given an ANCAP star rating, given it shares so much with the five-star rated E-Class we’d expect it to score nothing less than that, too.
Along with nine airbags, ABS, and traction and stability control the level of advanced safety equipment onboard the new CLS is seriously impressive. There’s the 'Driving Assistance package Plus' which brings AEB with cross traffic function, evasive steering, blind spot warning with an active function and lane keeping assistance.
For child seats you’ll find two ISOFIX mounts and three top ether anchor points.
Porsche Panamera
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.
Ownership
Mercedes-Benz CLS-Class7/10
The CLS is covered by Mercedes-Benz’s three-year/unlimited kilometre warranty. Servicing is recommended every 12months/25,000km for the CLS 350 and CLS 450, while the CLS 53, like all AMGs needs to visit at 12month/20,000km intervals.
Mercedes-Benz says a capped price servicing plan will be available, but has yet to release the prices. We’ll update this as soon as the costs have been announced.
Porsche Panamera
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.
