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 718
Porsche has taken its entry-grade 718 Cayman and created a special Style Edition which adds more features and some nice aesthetic touches to what is one of the best and relatively affordable, prestige sports cars on the planet.
What makes this car even more special is knowing Porsche will adopt an electric powertrain for the next Cayman. Yup, this is one of the final Caymans to have a combustion engine. Talk about a limited edition.
So what’s not to love? Well, you’ll have to read on to find out because although the 718 Cayman Style Edition is wonderful in so many ways, there are some sides to it you need to know about before diving into the ownership experience.

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 7187.3/10
The 718 Cayman Style Edition only costs a bit more than the entry-grade Cayman it's based on, but opens up more special colours and contrasting features from the wheels to decals, even leather upholstery. The value is good, the look is enhanced and the car remains superb to drive on the right roads.
Living with a Cayman daily is ‘do-able’ but you’ll have to be understanding given it's not the most user-friendly car to drive, and then there’s the low-level safety tech.
But in return, you’ll own one of the best and relatively affordable prestige sports cars ever made and one of the last of the combustion-powered Porsche Caymans.
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 7188/10
The 718 Cayman is often labelled as the 'junior 911' but that downplays its status as an outstanding sports car in its own right.
It’s not a smaller version of the 911, at all, but it is smaller than a 911. Not by much, though. The Cayman is 140mm shorter in length than the 911 at 4379mm end-to-end. Interestingly, the Cayman has a longer wheelbase at 2475mm and is taller at 1295mm.
The 718 Cayman is beginning to date in its design with this generation of the sports car arriving eight years ago. From the outside it’s holding up well in terms of styling , but inside it feels very 2016 with the small media screen and analogue dials.
It gives me a weird nostalgic feeling I normally only get driving older cars, but in a current model. Which could be why Porsche is jazzing the Cayman up with this Style Edition.
The Style Edition enhances the look of the entry-grade Cayman with 20-inch 718 'Spyder' wheels in a high gloss black or white finish, and there’s a choice of six special colours ranging from the Crayon hue our car wore to 'Ruby Star Neo', 'Shark Blue', 'Carmine Red' and 'Arctic Grey'.
The Style Edition also adds black sport tailpipes, full-colour Porsche crests on the wheel hub covers, a black leather interior with contrasting Crayon stitching, Porsche crest embossed headrests, illuminated door sills and floor mats with Crayon contrast stitching.
Buyers can also choose a 'Contrast Package' in black or white which adds Porsche lettering to the side of the car and a strip to the bonnet.
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 7187/10
The 718 Cayman doesn’t have back seats - it's a two-seater sports car. Cabin storage is almost non-existent but is saved by a glove box and pull-out door pockets which are bigger than they look.
Surprisingly, there are three cupholders - two which pop out of the dashboard above the glove box and another in the small centre console bin.
Cargo space isn’t bad for a two-seater sports car with 184-litre rear boot and a front boot with a 150-litre capacity. That’s roughly one nine-year old child as you can see from the photos. My son wanted to sit in there, which I agreed to, but I said no when he asked me to shut the bonnet.
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 7188/10
The 718 Cayman Style Edition lists for $136,700 and this is for the manual version, the auto is $5340 more. All up Porsche is asking $4200 more than the entry-grade Cayman it’s based on. In return you’re getting some nice features you won't find on the standard model.
There's the chunky black exhaust tips, the full-coloured crests on the wheel caps and inside is the black leather interior package with embossed headrests, illuminated door sills, and floor mats with 'Crayon'-coloured stitching.
Buyers can also specify one of two Style Edition contrast packages - one in Black and one in White - at no extra cost. Ours had the Black package specified and added the Porsche decals to the side of the car, the stripe on the bonnet and the gloss black 20-inch wheels.
The colour of our car was Crayon which comes as part of the bespoke colour offerings with the Style Edition.
Along with these Style Edition features there are the standard features of the entry-grade Cayman, including LED headlights, proximity unlocking, power adjustable sports seats, media display with sat nav, Apple CarPlay and dual-zone climate control.
If you’ve been driving new cars lately you might be a bit disappointed by the Cayman’s small media display (it’s a 7.0-inch screen which is tiny by today’s standards) there’s also no Android Auto available (just Apple CarPlay) and safety tech is relatively light-on, too. You can read about this further down.
It should be pointed out here that our car was fitted with a dual-clutch automatic transmission and the optional adaptive cruise control ($2320).
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 7188/10
So, under the bonnet of a Cayman is the front boot, but if it’s the engine you’re after you’ll need to go through the rear hatch because this is a mid-engined car.
Getting to the engine means removing several fixtures and covers which begins to feel like you’re dissembling the vehicle and comes with a rising anxiety that it all won’t go back together.
But it all clicks back in. It’s just a slow and tedious process. Fortunately, oil and water can be added by removing the circular covers you can see in the images.
Under the layers of covers, deep down just in front of the rear axle, is the Cayman’s 2.0-litre ‘flat’ four-cylinder turbo-petrol engine which makes 220kW and 380Nm. A seven-speed dual-clutch automatic transmission sends drive to the rear wheels.
It’s not a huge amount of power but the Cayman only weighs 1365kg and so can get from 0-100km/h in 5.1 seconds. Not brutally quick but the way this car handles is what you’ll like.
Oh, and just to be clear, the Style Edition doesn’t bring any extra power or engine changes. The outputs and performance are the same as the entry-grade Cayman.
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 7187/10
Porsche says that after a combination of open and urban roads the Cayman’s fuel consumption should be 7.0L/100km. My 143km fuel test, taking in country roads and school runs, used 21.8L of petrol and equates to 15.2L/100km. Which means I had about twice as much fun as Porsche did when it recorded its fuel consumption.
The 64-litre tanks means in theory you should be able to travel 914km between fills if you’re conservative with fuel.
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 7189/10
The 718 Cayman Style Edition doesn’t come with any performance advantages over the already brilliant entry-grade Cayman it’s based on. And it is brilliant to drive. Several big steps above Audi’s TT, Nissan's Z or Toyota and BMW’s Supra/Z4 'twins under the skin' in terms of handling, steering and engagement.
That said, the Cayman isn’t as easy to drive as any of those cars. The steering is heavy, the accelerator is stiff, the dual-clutch auto transmission feels a bit rough and the turbo lags, then sends in the mumbo a bit too fast and too late. Oh, and and the seats are a tad tight.
But I can overlook all of this because on good winding country roads the Cayman feels like a water drop running down a wall, moving naturally and harmoniously around whatever it encounters.
The day-to-day school runs and grocery getting isn’t quite as poetic, and a Cayman proves challenging in the real world over potholes and in supermarket car parks. You’d have to love the Cayman for better or worse, as many do, to live with it daily. If you can't, there's the Audi TT.
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 7185/10
The almost complete lack of standard advanced safety technology on board the Porsche Cayman might be a deal-breaker for you. There’s no AEB (forward or reverse), no cross-traffic alert and no lane keeping assistance. But there is blind-spot warning, front and rear parking sensors and a reversing camera. Adaptive cruise control is a $2320 option.
The 718 Cayman hasn’t been crash tested and therefore doesn’t have an ANCAP rating, but you’ll be pleased to know there are four airbags covering the driver and passenger.
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 7186/10
The Cayman Style Edition is covered by a three-year/unlimited kilometre warranty and servicing is needed every 12 months or 20,000km.
With Porsche, final service costs are determined at the dealer level (in line with variable labour rates by state/territory).
We'd like to see the warranty coverage increased to five years/unlimited kilometres which will bring it in line with more mainstream brands.
