Audi Q2 vs Mercedes-Benz CLS350

What's the difference?

The Q2 is good value and great to drive – especially the SQ2. The exterior looks new, but the cabin feels older than the larger Q3, and most other Audi models.

More standard advanced safety tech would make the Q2 even more appealing, as would a five-year, unlimited-kilometre warranty. While we’re at it, a hybrid variant would make enormous sense. 

So, a great car, but Audi could offer more to make it an even better proposition for buyers. 

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.

This updated Q2 looks almost identical to the previous one and really the only changes are subtle styling tweaks to the front and back of the car.

The front air vents (they aren’t real air vents on the Q2, but they are on the SQ2) are now larger and pointier and the top of the grille is lower. Around the back, the bumper now has a similar design to the front, with those pointy polygons set wide apart.

It’s an angular little SUV, full of sharp-edged shapes like some kind of acoustical wall in an auditorium.

The SQ2 just looks more aggro, with its metallic-trimmed air vents and beefy quad exhaust. 

The new colour is called Apple Green and it’s not really like any colour on the road – well not since 1951, anyway when this hue was hugely popular on everything from cars to telephones. It’s also very close to Disney’s “Go Away” green – look it up and then ask yourself if you should be driving a car that’s kind of invisible to the human eye.

I digress. Other colours in the range include Brilliant Black, Turbo Blue, Glacier White, Floret Silver, Tango Red, Manhattan Grey and Navarra Blue.

Inside, the cabins are the same as before, apart from the larger, sleeker media display, and there are some new trim materials, too. The 35 TFSI has silver inlays with a diamond paint finish, while the 40TFSI has aluminium door sills.

The Q2 has beautiful quilted Nappa leather upholstery, which goes beyond just covering the seats and to the centre console, doors and armrests.

All options offer well laid out and premium feeling cabins, but the disappointing part is that it's an older Audi design, which started out in the third-generation A3, launched in 2013, and still exists on the Q2, even though most Audi models, including the Q3, have the new interior design. This would bug me if I was thinking about buying a Q2. 

Have you thought about a Q3? It’s not that much more in price, and it’s a tad bigger, obviously. 

The Q2 is tiny, at 4208mm end to end, 1794mm wide and 1537mm tall. The SQ2 is longer at 4216mm long, 1802mm wide and 1524mm tall.  

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'.

The Q2 is basically a current model Audi A3, but more practical. I’ve lived with the A3 Sedan and Sportback and while rear legroom is just as confined in those as it is in the Q2 (I’m 191cm and need to squish my knees behind my driving position) getting in and out is easier in the SUV, with its elevated ride height and taller door apertures.

The easier access helps enormously when helping kids into their child seats. In an A3 I need to kneel on the footpath to be at the right level to put my son into the car, but not with the Q2.

The boot space of the Q2 is 405 litres (VDA) for the front-wheel-drive 35 TFSI and for the SQ2 it’s 355 litres. That not bad, and the large hatch makes for a big opening, which is more practical than a sedan’s boot.

Inside, the cabin isn’t enormous, but rear headroom is good, thanks to the fairly high roof.

Cabin storage isn’t terrific, although the front door pockets are big and there are two cupholders up front.

Only the SQ2 has USB ports in the back for rear passengers, but all Q2s have two USB ports up front for charging and media – plus all have wireless charging for phones.

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 three grades and each has a different engine. 

The 35 TFSI has a new 1.5-litre four-cylinder turbo-petrol engine making 110kW and 250Nm; the 40 TFSI has a 2.0-litre turbo-petrol four making 140kW and 320 Nm; and the SQ2 has a 2.0-litre turbo-petrol as well, but it puts out a very impressive 221kW and 400Nm.

The 35 TFSI is front-wheel drive, while the 45 TFSI quattro S line and SQ2 are both all-wheel drive.

All have a seven-speed dual clutch automatic transmission – nope you can’t get a manual. There are also no diesel engines in the line-up.

I drove all three cars and, from an engine perspective, it’s like turning the ‘Smile Dial’ up from Mona Lisa in the 35 TFSI, to Jim Carrey in the SQ2, with Chrissy Teigen in between.

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.

Audi engines are superbly modern and efficient – even its monster V10 can shut down cylinders to save fuel, and so can the new 1.5-litre four-cylinder engine in the 35 TFSI. Audi says that over a combination of urban and open roads, the 35 TFSI should use 5.2L/100km.

The 40 TFSI is thirstier at 7L/100km, but the SQ2 demands a bit more at 7.7L/100km. Still, not bad. 

What’s not good is the lack of a hybrid, PHEV or EV variant of the Q2. I mean the car is small and ideal for the city, and therefore a perfect candidate for an electric version. Not having a hybrid or EV is why the Q2 model range doesn’t score well for its overall fuel economy.

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.

When it comes to the driving part, Audi can almost do no wrong – everything the company makes, whether it’s low powered or rip-your-face-off fast, has all the ingredients for engaging driving.

The Q2 range is no different. The entry-grade 35 TFSI has the least grunt and, with its front wheels pulling the car along, it’s the only one in the family that’s not blessed with all-wheel drive, but unless you’re doing laps at a track you’re not going to be wanting more power. 

I drove the 35 TFSI for more than 100km on the launch, through the country and into the city, and in all situations, from overtaking on highways to merging and slow traffic, the most affordable Q2 performed well. That 1.5-litre engine is responsive enough and the dual-clutch transmission changes swiftly and smoothly. 

Superb steering and good visibility (although that rear three-quarter view is slightly obstructed by the back pillar) makes the 35 TFSI easy to drive.

The 45 TFSI is a good mid-point between the 35 TFSI and the SQ2 and comes with a very noticeable bump in oomph, while the extra traction from the all-wheel drive is a reassuring addition. 

The SQ2 isn’t the hardcore beast you might think it is – this thing would be super easy to live with daily. Yes, it has firm sports suspension, but it’s not overly hard, and that engine, which nudges almost 300 horsepower, doesn’t feel like a Rottweiler on the end of a leash. If anything, it’s a Blue Heeler that loves to run and run, but is happy to take it easy and get fat.  

The SQ2 is my pick of the bunch, and not just because it’s quick, agile, and has an intimidating growl. It’s also comfortable and luxurious, with sumptuous leather seats.  

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 pressure for Audi to move to a five-year warranty must be hugely intense, with Mercedes-Benz offering one, along with pretty much every other mainstream brand. But for now, Audi will only cover the Q2 for three years/unlimited kilometres.

As for servicing, Audi offers a five-year plan for the Q2 costing $2280 and covering every 12-month/15000km service over that time. For the SQ2, the cost is only a fraction higher at $2540.  

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.
