Mercedes-Benz GLC300 vs Skoda Superb

What's the difference?

The GLC300 Coupe isn't quite as great when it comes to being a family car as the regular SUV version of the GLC, and that's purely down to the sloping roofline which not only makes access more difficult to the second row but reduces boot capacity.

That said, the GLC300 Coupe makes a much better family car than a Mercedes-Benz C-Class sedan, or any sedan.

Easy and enjoyable to drive, packed with great features and still practical, the GLC300 Coupe would still cut it as a good family car.

It’s safe to say the Skoda Superb is well… superb.

This car has consistently been one of my favourites, and that’s not something I say lightly. It's a fantastic package that combines all the best parts of comfort, practicality and driving dynamics.

All of those points stand out as key reasons why, despite the fact Australians are no longer buying passenger cars in substantial numbers, you should consider this over a similarly-sized SUV.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.

Coupe SUVs aren’t for everybody… they’re not even for lots of people. But the design of an SUV with its roof cut down so that it meets the tailgate at an almost sportscar-like angle appeals to more than a few fans. The thing is they don’t just like the look, they love it, and they also probably enjoy how much the styling makes other people cranky.

To my eyes the GLC300 Coupe is the best execution of the bodystyle compared to those of BMW and Audi. There’s an elegance to the GLC300 Coupe and the AMG-line adds a tough look that only enhances the solid, powerful but pretty look.

The GLC Coupe is a mid-sized SUV and this new generation model is a bit bigger the previous one and now measures 31mm longer at 4763mm end to end, it’s 1890mm wide, 1605mm tall and has a wheelbase of 2888mm.

It’s also more aerodynamic than ever. No seriously, it’s drag coefficient is now 0.27 and it looks like a bar of soap - and it's about as slippery as one, too.

More curved surfaces await inside with a dashboard that pours down into the large centre console and it's adorned with a sloping and large portrait-style media screen. 

At night or in tunnels the ambient lighting glows through the air vents and skirts the edges of the door trims, console and dashboard.

It’s a minimalist and high-tech cockpit with modern sports seats up front and a Nappa leather wrapped steering wheel with its twin blade design.  

So, how does the coupe design work for family practicality? Let’s take a look.

On the outside of the new Skoda Superb its design is more of an evolution than revolution. This is no bad thing because I’ve always been a big fan of the Superb’s exterior design, even more so now because it’s the only one of its kind left.

From a lot of angles this new Superb gives major Holden ZB Commodore vibes, especially the wagon from the rear three-quarter.

While I like the sporty looks and glossy black highlights, I wish Skoda still offered a non-Sportline version of the Superb locally. Globally there are premium L&K versions available with chrome accents, and they look properly premium-pushing.

Inside, the Superb is a classic flagship Skoda through and through. It balances having beautifully high-end finishes with TARDIS-like practicality with ease.

Ahead of the driver there’s a sporty-looking perforated leather steering wheel which has Skoda script written out on the hub, rather than the classic winged arrow Skoda logo.

It’s an interesting look that forms as part of the new corporate design language. I imagine I’ll get used to it after a while, and it's all subjective, but I’m currently not a huge fan.

Looking around the cabin, the interior is dominated by the new 13-inch touchscreen multimedia system that’s high-resolution. It’s mounted high on the dashboard much like an iPad, which mightn’t be to everyone’s taste.

Flanking this new touchscreen is an interesting slotted air vent design that spans the entire dashboard. It’s a really cool look, though it’s finished in glossy black and will likely gather dust easily.

Speaking of black, a lot of the Superb’s interior is finished in black. I wish there were more pops of colour, whether that's with different finishes or textures to create some visual interest.

SUVs are the most practical cars for families because of the better access to the cabin thanks to their large doors and slightly elevated ride height, their big boots with wide and tall hatch openings and their high flat rooflines. They’re essentially raised station wagons.

A coupe-style SUV still has four doors but they are less boxy due to the sloping roofline which falls away quickly to meet the tailgate at a lower point. The effect is a sporty-looking shape but practicality is lost in this exercise of form over function.

The second row doorways aren’t as large as those on the regular SUV. I did a side-by-side test and felt like I had to duck under the sloping roof when getting out of the back seat.

The smaller opening also made it trickier to lift my toddler daughter into her baby seat.

The sidesteps are also surprisingly handy for bigger kids and my eight-year-old used them every time when climbing into the car.

Cabin storage is outstanding with huge door pockets and cupholders in both rows, and while the 545-litre boot in the GLC300 Coupe is 80 litres smaller than the cargo capacity of the regular GLC SUV, it's bigger than the previous version of the Coupe.

As for people space, there’s enough headroom for me at 189cm tall in the back seat and heaps of legroom, even behind my driving position.

I’ve mentioned the lack of climate control in the second row, but also should point out that there are no USB ports back there either.

There are USB ports in the big centre console box upfront and a long cord should be able to make it to the second row. 

There’s a wireless phone charger but it's housed in the bowels of the centre console too, and you’ll need to weave your hand while clasping the phone under the shiny black trapdoor, past the cupholders possibly with drinks in them and almost under the dashboard.

This is where this car properly shines.

Up front there are deliciously comfortable leather seats that are electrically adjustable, heated, ventilated and have a massage function. The heating was well and truly cranked during our drive loop around chilly Canberra and it kept me nicely warm and toasty.

I also enjoy how adjustable the front seats are. No matter how tall or short you are, you’ll find a comfortable seating position.

As mentioned above there’s a leather steering wheel ahead of the driver which has perforations on it. This is handy if you get clammy hands out on the road. And I like how warm the steering wheel gets when the heating is turned on. In fact, it almost gets too hot.

The 10-inch digital instrument cluster behind the steering wheel is classic Volkswagen Group in terms of layout and design. It offers what feels like limitless configurations, allowing you to tailor the information you want to see.

Moving across, this larger 13-inch touchscreen multimedia system is a breeze to use. It features new software compared to the previous-generation Superb that looks considerably fresher.

The home screen can be configured and there are easily accessible shortcut buttons on the screen for things like the vehicle settings menu, among others.

I’m a particular fan of the shortcut buttons at the top of the touchscreen that show your favourite settings in the vehicle menu. You’re able to toggle things like auto hold, engine idle start-stop and numerous other features.

Underneath the touchscreen is one my favourite parts of this car. There are three physical rotary dials that initially look like they’re just for adjusting the climate control functions, but can do so much more. They’re called ‘Smart Dials’ and also feature in the new Kodiaq.

The outer two dials are able to adjust things like the temperature, as well as the seat heating and ventilation, whereas the centre dial can change the fan speed, air direction, driving mode, sound system volume and zoom function on the sat-nav map.

They’re incredibly intuitive to use and have fantastic tactical clicks when interacted with. It’s fantastic to see a new car that puts such a big emphasis on still having physical hardware, instead of opting for the minimal look that requires you to use the touchscreen for everything.

Another big change with the Superb is the gear selector has been relocated from the centre console to the steering column. This has been happening to a range of Volkswagen Group vehicles of late.

As a result, the centre console has been redesigned with maximised storage in mind. There are now things like a display cleaner and many generous storage spaces.

Also if you want to securely store items, there are retractable covers on the centre console which also help give it a clean look.

Moving to the second row, it’s an amazing place to sit. There is so much space on offer that it puts every single similarly priced and sized SUV to shame. You can’t beat a large sedan or wagon in terms of practicality.

Second-row amenities include heated outboard seats, retractable sun-blinds, a fold-down armrest with cupholders and a tablet holder, as well as airplane-style head restraints that fold out from either side of the head rest.

Regardless of where you sit in the Superb, you’ll be in proper comfort.

Around the back is the showstopper. As standard there’s a hands-free power tailgate which is handy if you’ve got hands full and need to open the boot.

Once the tailgate opens there’s a generous amount of boot space on offer. Skoda claims the Superb liftback has a 589L capacity with the rear seats upright, expanding to 1795L with them folded.

With the wagon on the other hand, there’s 634L of boot space with the rear seats upright, expanding to a massive 1920L with the second row lowered.

‘Simply Clever’ touches include an electrically retractable luggage cover, a retractable luggage sling, moveable luggage separators, and a vast net system.

Under the boot floor there’s a space-saver spare wheel.

The new Skoda Superb continues to only be offered in flagship Sportline trim level in either liftback or wagon body styles.

Pricing starts at $67,990, before on-road costs, for the liftback and extends to $69,690 before on-roads for the wagon.

While this is a circa-$2500 price rise over the outgoing model, Skoda has packaged in a considerable amount of equipment that was previously locked away in option bundles. As a result, this car is fully loaded.

Outside there are slimmer matrix LED headlights, new design 19-inch alloy wheels, gloss black exterior highlights, dynamic indicators and a hands-free power tailgate.

Inside there are new sport seats with integrated head rests that are also electrically adjustable, heated, ventilated and have a massage function.

Other interior highlights include a heated steering wheel, 10-inch digital instrument cluster, 13-inch touchscreen multimedia system, 12-speaker Canton premium sound system, wireless charging with ventilation, roll-up rear sunshades and heated outboard rear seats.

On the dynamics front, the new Superb picks up 'Dynamic Chassis Control Plus', which is essentially Skoda-speak for adaptive dampers. It’s an updated version which features two independently controlled valves, and allows for 15 stages of configurability. There’s now also progressive steering.

The GLC300 Coupe has a 2.0-litre four-cylinder turbo-petrol engine making 190kW of power and 400Nm of torque.

There’s also an overboost function which allows the engine to make an extra 17kW and 200Nm just for a brief moment, but that extra dollop of grunt combined with the regular output provides impressive acceleration (0-100km/h in about 6.3 seconds) for overtaking or moving quickly when you need to.

A smooth nine-speed automatic transmission sends the drive to all-four wheels.

The GLC300 Coupe is all-wheel drive and while there’s a setting for rougher terrain, along with one for comfort, eco and sport, but I’d make sure that it doesn’t get any more adventurous than tame gravel and dirt roads.

Mercedes-Benz refers to the GLC300 Coupe as a mild hybrid and this is because it has a 48-volt system and an integrated starter-generator.

This type of hybrid doesn’t use electric motors, doesn’t drive the wheels and won’t save much fuel, but it will provide efficiencies by supporting the engine and when coasting, plus will reduce petrol consumption to a small degree.

The new-generation Skoda Superb is still powered by a 2.0-litre turbo-petrol four-cylinder petrol engine, but it has been upgraded.

It produces 195kW of power, which is technically 9.0kW less than the previous-generation version, and 400Nm of torque, which is 50Nm more.

It’s worth noting this engine also features in the new Skoda Octavia RS, as well as the Volkswagen Golf GTI and Tiguan R-Line.

The engine is mated to a seven-speed dual-clutch automatic transmission with drive sent through an all-wheel drive system.

As we mentioned above the GLC300 Coupe's 48-volt mild hybrid system is not the kind of hybrid that will allow you to drive miles on electric power, nor will it dramatically reduce fuel consumption in the way a parallel, series or plug-in hybrid will. But every bit of efficiency helps.

Mercedes-Benz says the GLC300 Coupe will use 7.7L/100km after a combination of open and urban roads. 

We had the GLC300 Coupe for just two days, but in that time my family covered 176km of regular daily usage which took in motorways but mainly suburban duties such as the school run, supermarket dashes, that sort of thing.

In our fuel test we measured 14.48 litres at the fuel pump which works out to be an on-test fuel use figure of 8.2L/100km and not far off the manufacturer’s claim. 

While this fuel consumption isn’t overly high, a plug-in hybrid or even a parallel or series hybrid could return about 5.0L/100km or less.

Mercedes-Benz has dropped plug-in hybrids from its Australian range which is a shame because it would be good to see more efficient options in the GLC range. Of course if you want more efficiency from a Benz of the same size, there is always the fully electric EQB or EQC.

While the new Superb is claimed to be faster, it’s also claimed to be more fuel efficient. In liftback guise claimed combined cycle (urban/extra-urban) fuel consumption is 7.7L/100km, while in wagon guise the official figure is 7.8L/100km.

The entire range comes with a 66-litre fuel tank and it requires a minimum of 95 RON premium unleaded.

With this claimed fuel consumption you could theoretically travel up to 850km on a full tank of petrol. In our test cars however, they were displaying 900km of range when we started off the drive loop.

Unfortunately the Superb doesn't come with any form of electrification, whether that be a mild-hybrid or plug-in hybrid powertrain. Skoda Australia is currently evaluating and testing the Superb PHEV, but if it does launch locally, it won’t be until 2026 at the earliest.

There’s a lot to like here but the short version is the GLC300 Coupe has a comfortable ride, but good handling, with a responsive engine, although rear visibility through the small back window is poor.

If we drill down a bit further I can tell you that excellent cameras around the car will help you check to make sure kids aren’t running around behind you and that forward and side visibility through the window is good.

An important takeaway is that the GLC300 Coupe is easy to drive with light steering and an engine that’s mild and controlled in its power delivery.

The gear shifter is mounted on the steering column, in the same way an indicator lever is. So putting the car into Drive, Reverse and Park is so easy and means you don’t have to take your hands off the steering wheel. 

As a family car I liked the good body control and composed ride. We have a small toddler that we can sometimes only get to sleep by taking her for a drive and we found that she could nod off and not be woken by potholes and speed bumps or too much leaning in the corners. 

Starting up the Skoda Superb Sportline you hear the familiar sound of this 2.0L engine, variations of which are used in numerous VW Group models. It’s fairly muted and smooth, which makes the cabin a serene place to be.

Setting off you use the column-mounted gear selector to change gears. It takes a little bit to get used to the new placement, but after a few uses it feels normal. This relocation has also allowed for so much more storage on the centre console.

Around town the Superb’s 2.0-litre turbocharged four-cylinder petrol engine barely makes itself known. The full 400Nm of torque comes on tap from as little as 1650rpm, making this car effortless to drive and almost turbo-diesel-like in practice.

Skoda claims the new Superb can do the 0-100km/h sprint in 5.6 seconds in liftback guise and 5.7 seconds in wagon guise. This is 0.3 seconds faster than the old version.

It barely requires any thought driving in the typical urban sprawl. The car does all the heavy lifting for you.

When it comes to parking, however, there’s no way around the fact this is a long car. You may find yourself needing to do three-point turns in order to navigate tighter urban car parks.

It doesn’t help that the surround-view camera system is surprisingly low-resolution, which is disappointing given the Superb is a flagship vehicle for Skoda. It’s more noticeable because the central touchscreen is incredibly high-resolution.

As standard there’s a seven-speed dual-clutch automatic transmission which has one more ratio than the previous-generation Superb. Though this isn’t necessarily obvious in everyday driving, the dual-clutch is still a classic Volkswagen Group unit, meaning it’s snappy and intuitive.

This car comes with a progressive ratio steering system which increases the amount the wheels physically turn as you feed on more lock with the steering wheel. It helps make the car feel more agile and sporty, while also requiring less effort.

With the updated adaptive dampers you can now configure the system in 15 different ways, which is wild. This spans all the way from beyond ‘Comfort’ through to ‘Sport’.

In ‘Normal’ mode the Superb still errs on the sportier side, which makes sense because the Sportline package is standard. This also brings a 15mm ride height reduction.

Despite feeling sporty as standard, the Superb is never uncomfortable. This is really surprising because there are sizeable 19-inch alloy wheels and low-profile tyres.

Dialling the car through to ‘Comfort’ mode makes the drive pretty much effortless. It’s incredibly comfortable and supple, ironing out virtually any road imperfection you can throw at it.

Unlike other Skoda vehicles with adaptive dampers, this Superb doesn’t get that bouncy cloud-like feeling in ‘Comfort’ mode. Instead, it still feels grounded.

There’s an ‘Eco’ drive mode which unsurprisingly prioritises fuel economy. It makes upshifts happen low down in the rev range, and also shifts the car into neutral when coasting.

Although the car is in ‘Eco’ mode, it doesn’t feel like you’re lacking any oomph. You’ll still be keeping up with urban traffic easily.

Slotting the Superb into ‘Sport’ mode immediately sharpens the throttle response and makes the car feel like it’s hunkering down, ready to attack. The suspension and adaptive dampers noticeably become stiffer, making you jiggle about in the driver’s seat more than in other drive modes.

It’s surprising how Sport makes this huge sedan and wagon feel much smaller than it is. This is likely credit to how dynamic the Volkswagen Group has made its 'MQB Evo' platform.

Thanks in part to the all-wheel drive system, this car is an absolute beast out in the twisties. You can take corners with a lot of heat and still feel incredibly in control.

Once again, the car does a lot of the heavy lifting, allowing you to focus on what’s going on with the road ahead. It’s very smile-inducing.

While this car is dynamic and thrilling to drive, it’s worth noting it’s no full-fat RS model. You reach a ceiling with the turbo-petrol’s outputs when accelerating hard, but there’s still plenty to play with. Only proper performance car nerds will care about this.

Out on the open road, the Superb becomes a great long-distance tourer. It feels like I could drive from Melbourne to Adelaide in one hit without stopping.

At higher speeds, however, there is a bit of road and tyre noise. This is common in European vehicles, but still ruins the ambience of the cabin if you don’t like listening to music behind the wheel.

More concerning, though, is the virtually brand-new Superbs we sampled at this media launch were already starting to develop noticeable rattles in the door cards. Underwhelming in a circa $70K car.

The new-generation Skoda Superb hasn’t been tested by ANCAP just yet, though Euro NCAP gave the car a maximum five-star rating. The two safety authorities have harmonised testing protocols so it’s likely the rating will eventually be carried across.

In terms of standard equipment, the Superb has 10 airbags, an upgraded autonomous emergency braking (AEB) system, blind-spot monitoring, front and rear cross-traffic alert, lane-keep assist, lane centering, adaptive cruise control, traffic sign recognition, driver fatigue detection, a surround-view camera, front and rear parking sensors and a semi-autonomous park assist.

There are ISOFIX points on the outboard rear seats, as well as top-tether child seat anchorages on all three rear seats.

The GLC300 is covered by Mercedes-Benz's five-year, unlimited-kilometre warranty. 

Services are annually or every 25,000km. And you can buy a three-year service plan for about $3000.

The new Superb, like all other current Skoda models, is covered by a seven-year, unlimited-kilometre warranty.

This warranty length is slowly but certainly becoming the standard in Australia.

At this stage Skoda hasn’t detailed service intervals or service pricing. It has said it’ll offer pre-paid service packages, however.
