Volkswagen Arteon vs Mercedes-Benz CLS350

What's the difference?

The value, driving dynamics and appearance are on point for a premium play here. If you can forgo the badge snobbery attached to the German big three, then you'll find lots to like about Volkswagen's Arteon.

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.

It's really all about the looks here, and while the Shooting Brake is particularly handsome, the regular Arteon looks premium and polished, too.

VW tells us injecting a bit of sportiness was a key aim here, both inside and outside, and that's particularly true of the R-Line model, which rides on bigger 20-inch alloys, compared to the 19s on the Elegance, with their own bespoke design.

The body styling is more aggressive, too, but both trims get lashings of chrome along the body work, and a sleek, swept-back style that looks more premium than overtly sporty.

In the cabin, though, you can see that this is an important car to VW. The touchpoints are almost all soft to the touch, and it's both understated and tech-saturated at the same time, including the swipe-to-adjust function for the stereo and climate, with new touch-sensitive sections added to the centre console and steering wheel.

It feels, dare we say it, premium. Which is likely exactly what VW was going for...

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'.

Interestingly, both body styles share near identical dimensions, with the Arteon stretching 4866mm in length, 1871 in width, and 1442mm in height (or 1447mm for the Shooting Brake).

Those numbers translate to a seriously spacious and practical cabin space, with an acreage of room for backseat riders. Sitting behind my own 175cm driving position, I had heaps of space between my knees and the seat in front, and even with the sloping roofline, plenty of headroom, too.

You'll find two cupholders in a pull-down divider that separates the back seat, and a bottle holder in each the four doors. Backseat riders also get their own air vents with temp controls, as well as USB connections, and phone or tablet pockets on the rear of each front seat.

Up front, the theme of space continues, with storage and cubbies sprinkled throughout the cabin, as well as USB-C connections for your phone or devices.

All that space means a sizeable boot area, too, with the Arteon serving up 563L with the rear seats in place, and 1557L with the back pews folded. The Shooting Brake ups those numbers - thought not any as much as you might think - to 565L and 1632L.

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.

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.

There are two drivetrains on offer here — the 140TSI with front-wheel drive in the Elegance, or the 206TSI with all-wheel drive in the R-Line.

The former's 2.0-litre turbo-petrol produces 140kW and 320Nm, which is enough for a sprint to 100km/h in around 7.9 seconds.

But the lust-worthy engine tune is definitely the R-Line, in which the 2.0-litre turbo-petrol ups the grunt to 206kW and 400Nm, and drops the sprint time to a brisk 5.5 seconds.

Both pair with VW's seven-speed DSG automatic.

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.

Volkswagen says the Arteon Elegance will need 6.2L per hundred kilometres on the combined cycle, and will emit 142g/km of C02. The R-Line needs 7.7L/100km on the same cycle, with emissions pegged at 177g/km.

The Arteon is fitted with a 66-litre tank, and a PPF or petrol particulate filter, which strips some of the nasties out of the vehicle's emissions. But, VW says, it's “very important" that you only fill your Arteon with premium feel (95RON for the Elegance, 98RON for the R-Line) or you risk shortening the life of the PPF.

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.

Full disclosure: we only spent time behind the wheel off the R-Line variant for this test, but even still, I feel pretty comfortable suggesting that it's the punchy powertrain you want.

Surely the very first hurdle any company hoping to play with the premium-brand big boys must clear is that of easy, effortless momentum? It's difficult to feel like you've made the premium choice when you're engine is straining and striving under acceleration, right?

And on this, the Arteon R-Line shines, with plenty of power underfoot whenever you need it, and a delivery style which means you rarely, if ever, fall into a hole waiting for the power to arrive.

For mine, the suspension might be a touch too firm for those seeking a truly wafting drive experience. For the record, it doesn't bother me — I always prefer to know what's happening underneath the tyres than be entirely removed from the experience — but a result of this sporty-feeling ride is the occasional registering of bigger bumps and road imperfections in the cabin.

The flip side of the firm(ish) ride is the ability for the Arteon - in R-Line guise - to swap personalities when you engage its sportier settings. Suddenly there's a snarl to the exhaust that's absent in its comfortable drive modes, and you're left with a vehicle that tempts you to head for a twisting back road to see what it's about.

But in the interests of science we instead headed for the freeway to put the Arteon's autonomous systems through their paces, with the brand promising Level 2 Autonomy on the highway.

While the technology still isn't perfect — some braking can occur when the vehicle's not entirely sure what's happening ahead of it — it's also pretty impressive, taking care of the steering, accelerating and braking for you, at least until you're reminded its time to put your hands back on the wheel.

It's also bloody big, the Arteon, with more space in the cabin - and especially the backseat - than you might be thinking. If you have kids, they'll be positively lost back there. But if you cart adults on the regular, then you'll hear no complaints.

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.

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.

The Arteon is covered by VW's five-year, unlimited-kilometre warranty, and will require servicing every 12 months or 15,000kms. It will also get VW's capped price servicing offer.

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.
