Mercedes-Benz GLC-Class vs Volvo C40

What's the difference?

The GLC43 will inevitably remain one of AMG's more popular models, given Australian apetites for performance cars and the popularity of the mid-size SUV segment.

While the GLC doesn’t move the game forward massively aside from its new engine - which is a huge plus for the SUV - BMW has a new generation of X3 on the way, which will undoubtedly feature a performance variant.

And keen drivers should keep in mind that Porsche’s impressive Macan SUV is available in sharp-driving variants like the GTS for not much more, or even an S for notably less. And chances are, they’ll be more satisfied on a winding or twisty road. However stock of the ICE Macan will run out soon.

But the AMG offers a balance between convenience, comfort, and performance that will suit plenty of customers, rather than excelling in one particular area.

The C40 becomes a compelling option in the electrified small SUV space, offering a premium look and feel, great range and tech inclusions at the price, as well as awesome on-road dynamics.

Its main downsides are the rear seat, which is compromised by its platform and design-led roofline, and the overwhelming power and added traction of the dual-motor makes the single motor less attractive on the value front.

Still, regardless of variant chosen, the C40 looks to offer a stand-out balance of price, range, and performance, against its traditional rivals and newcomers alike.

The AMG GLC43, as you’d expect, has a few immediate give-aways that it’s no regular GLC300.

The vertical grille slats, the lower part of the apron featuring covered-up intake-style designs, and a different set of 20-inch AMG wheels are the easiest things to spot.

But the aforementioned Night pack, which adds black trim to the performance SUV, as well as the quad-exit exhaust tips instead of dual-exit on the GLC300 might be the most quantifiable way to explain the differences to the uninitiated.

In terms of dimensions, the GLC43 is now 67mm longer for the SUV, or 43mm longer in Coupe form. Both have an 11mm wider wheel track, and a 15mm longer wheelbase.

Inside, it’s quite similar to the 300, save for the AMG steering wheel and elements like the contrast stitching in the leather upholstery.

While other - especially more luxury-focused - Mercedes models have moved to a new interior design language with features like the Superscreen or Hyperscreen spanning the dash, the GLC’s interior still looks and feels suitably premium, and hasn’t dated much since being introduced.

The same can be said for its exterior, following relatively small changes over the still good-looking previous generation.

Volvo has become a brand with a distinctive and consistent design language which embodies the kind of beautiful minimalism normally associated with Scandinavian brands.

I have always liked how Volvo says more with less design elements, with only gentle touches of chrome or gloss black, and a lack of over-the-top sporty pieces avoiding the temptation to over-sell the sporty potential of the brand’s range.

The C40 takes the small SUV formula, well established by its XC40 relation, and gets a bit weird and experimental. It’s slightly lower and has a more coupe-styled rear, with a strongly raked rear window giving it a sportier and more aggressive look than the rest of Volvo’s SUV range.

The styling is sold by an angular spoiler piece running atop the boot, and the rear light clusters have gone all minimalist, constructed of individual pieces rather than a single transparent housing, and they give a nod to the C30 hatchback which this car is the spiritual successor to, by name and nature.

The interior offers up no surprises, sticking to the formula Volvo has established across all of its current models. An effortlessly premium space with, again, a minimalistic dash dominated by the portrait touchscreen, the C40’s premium nature is confirmed by its finely patterned inlays, simple chrome pieces, and abundance of soft-touch surfaces.

The big upright vent fittings with clever rhomboid patterns on their adjustment dials are always a highlight piece of modern Volvos, and the pattern work is continued on the central volume adjust dial and even on the little rotating pieces of the light and wiper stalks. Clever.

Even the software is paired back on the multimedia suite and digital dashboard, with easy to use shortcuts and simple menus which suit the car.

Volvo might turn off some buyers with the more unconventional shape of the C40. But for those looking for a more traditional SUV it also offers the XC40 in the same two variants, and the Polestar 2 caters to those not looking for an SUV at all.

The GLC’s interior feels more spacious than in its predecessor, and its ergonomics have been improved a little with the removal of elements like the touchpad control for the multimedia.

The software itself is quite easy to use on the touchscreen itself, removing the need for a physical control, and it’s rather customisable. 

Users are able to even adjust what order the drive modes appear in, and change what the two AMG Dynamic Select control dials on the steering wheel display or change.

The wheel itself is comfortable to hold, but its two-tier rows of controls and the lack of distinct physical buttons is a downside.

There is however plenty of storage, the central cubby and glovebox have space for all your assorted bits and pieces, and the door cards are able to accommodate even the biggest of bottles.

In terms of seats and comfort, the GLC’s cabin doesn’t feel cramped at all, with the seat itself supportive and adjustable to an impressive extent.

Space in the second row is comfortable rather than massively generous, but feels more spacious thanks to plenty of light via the sunroof.

The Coupe’s rear seat also does a decent job of accommodating average-heighted adults.

Behind that, 620L of boot space in the SUV and 545L in the Coupe are 40 and 45 litres more than the previous models, respectively.

The C40 is essentially a XC40 with a cropped down roofline, and there are some obvious downsides which this new shape brings.

The front seat throws no surprises, though, offering plenty of room for two adults with a welcome level of adjustability for the seat and wheel. The seats could be more comfortable, though, with a notable lack of padding in the base compared to some luxury (or even non-luxury) rivals. 

I’m a fan of the fabric trim which comes on both grades, bucking the trend of needing to have leather or leather-like trim for a car to feel ‘premium’.

The ample window space up front, including the massive glass roof helps the C40’s cabin feel spacious, but the view out the rear with its aggressive design is all but a very limited letterbox aspect, particularly if the rear seat headrests are in the upright position. 

While some controls are exclusively via touch interface, there is a physical volume dial, and shortcut buttons for the defogger functions. 

Temperature is controlled by touch, however, and the detail settings have some smaller toggle adjustments. Tricky to jab at when you’re on the move.

The digital dash is refreshingly simple, but minimally adjustable, with the choice of either a nifty navigation screen, a blank screen, or trip details being the only options.

Cabin storage is good but not stellar. There are bottle holders and big pockets in the doors, a set of two cupholders in the centre (beats the Polestar 2’s single cupholder), a small tray with a wireless charger under the multimedia screen, and a smallish console armrest box.

The rear seat is where the real problem exists. Unlike the XC40, the C40’s cropped roofline means my head was hard up against the roof (I’m 182cm tall). 

I did have decent knee room behind my own seating position, however the seat comfort in the back still isn’t as good as some rivals. 

The middle position is also compromised, thanks to the raised centre floor piece the C40’s platform needs to facilitate all-wheel drive in its combustion relations.

A bottle holder appears in each door pocket, and in a rare inclusion, there are heated outboard rear seats, adjustable air vents, and USB-C charging ports.

The boot has a quoted capacity of 413 litres with the rear seats up. The floor is comparatively high suggesting a smallish space when loaded with luggage cases, for instance. Stay tuned for a follow-up review so we can see how well it holds our three-piece demo set.

The floor itself has an adjustable, pop-up divider and multiple luggage hooks, making it quite versatile, and there is a cavity beneath which can hold your charging cables as well as the inflator kit in place of a spare wheel.

When it comes to electric vehicles, it’s impossible to consider price alone, as you also have to consider driving range, and the C40 manages to impress on both fronts.

Its refreshingly simplified range consists of just two highly-specified variants, a single motor which starts from $74,990, offering a 434km driving range, or a dual motor starting from $82,490 which offers a 420km driving range.

There’s much more devil in the detail, but to set the scene there are now quite a few direct rivals in this price-bracket, including everything from the Tesla Model Y (from $72,300), Mercedes-Benz EQA (from $78,513), Polestar 2 (from $63,900) and even the Kia Niro which is similarly sized and specified (from $65,300).

Interestingly, the C40 is closely related to the Polestar 2, but has a much higher base starting price. Volvo says this is because it carries a higher standard specification, and offers the C40 without option packs.

Standard gear on the base single motor C40 includes 19-inch alloy wheels, a 9.0-inch portrait multimedia touchscreen (running a Google-based always-online software suite), LED headlights, dual-zone climate control, a fixed panoramic sunroof, electrically adjustable front seats, heated seats for the front two and outboard rear seats, a powered tailgate, as well as keyless entry with touch-free ignition.

Interestingly, Volvo also told us some 90 per cent of customer interest so far has been for the more expensive dual-motor variant, which is particularly impressive for doubling the power output while adding 20-inch alloy wheels, a 360-degree parking suite, premium Harmon Kardon audio, and an alternate interior trim.

Both variants score safety equipment and items which are otherwise part of expensive option packs in the Polestar 2 range. We’ll take a look at the full safety gear later in this review.

Overall, the C40 impresses on the premium car value front compared to rivals, bolstered by solid range and impressive performance.

This is where the AMG version of the GLC really outshines the ‘standard’ GLC300, and starts to justify the extra ask over its $103,370 sticker price.

Like the GLC300, the AMG GLC43 has a turbocharged 2.0-litre four-cylinder petrol engine, which is paired with a nine-speed automatic transmission sending drive to all four wheels.

But unlike the 300, the AMG GLC43 borrows its engine from the likes of the AMG A45S, the M139 engine which puts out 310kW and 500Nm thanks to some seriously impressive engineering - and a lot of turbo pressure.

AMG’s one builder, one engine policy (they call it “One Man, One Engine”) means each engine in a GLC43 has been built by a sole expert engineer who has been certified to a high degree.

A 48-volt ‘mild-hybrid’ system is also present in the GLC43, which helps keep the turbocharger spinning (at up to 175,000rpm) to be more responsive, eliminating turbo lag.

The nine-speed auto is also slightly higher-tech than the GLC300’s, a wet start-off clutch replaces the traditional torque converter, which AMG says is lighter and more responsive - also featuring a double de-clutch function for faster shifts.

The AMG Performance version of the 4MATIC all-wheel drive system permanently diverts power to all four wheels with a 31 to 69 per cent front-rear distribution.

Mercedes-AMG claims the GLC43 is able to hit 100km/h from stand-still in just 4.8 seconds.

For reference, the old GLC43 (with a turbocharged inline six) made 287kW/520Nm and was a 4.9sec to 100km/h car.

Great news here, the C40 can be chosen with two powerful layouts, either a front-wheel drive 170kW/330Nm set-up, or a dual-motor all-wheel drive arrangement, able to make use of nearly double the power at 300kW/660Nm. The dual-motor is capable of sprinting from 0-100km/h in just 4.7 seconds.

The front-drive is backed by a 69kWh battery allowing it a 434km range, while the dual motor ups the battery size to 78kWh to allow a 420km driving range.

Mercedes-Benz says the AMG GLC43 consumes 9.7 litres for every 100km travelled in an SUV, or 9.9L/100km in the Coupe version, We were unable to properly test both of these figures on the launch.

Both have the same 62-litre fuel tank, and require premium RON 98 fuel.

CO2 emissions are rated at 219g/km for the SUV and 223g/km for the Coupe.

On test, after an hour of driving the GLC43 quite dynamically, the fuel consumption displayed on the trip computer sat around 15L/100km, so regular driving is sure to return a figure closer to Mercedes’ claim.

Surprisingly, energy consumption is quite high for both C40 variants. The single motor is the more efficient of the two, consuming 16.8kWh/100km on the more lenient ADR testing schedule, while the dual motor officially consumes 22.2kWh/100km to the same standard. I saw around 23kWh/100km overall in my short test of the dual-motor variant.

Energy consumption could be better for both, as I have achieved more consistently impressive results particularly from Hyundai and Kia electric cars.

Where the C40 is more impressive though is its charging specs, which are exactly where they need to be for a car this size. On a rapid DC charger, the C40 can charge at a rate of 150kW meaning a 10 - 80 percent charge in 40 minutes for the dual motor, or 32 minutes for the single motor.

On the slower AC standard, the C40 charges at a rate of 11kW. Expect a 10 - 80 percent charge time of around five or six hours on this standard. 

The C40 uses a European-standard Type 2 CCS charging port, although it misses out on the handy two-way charging feature offered by some rivals.

A long drive loop that consisted of limited sections of tight twisty roads meant getting to know the GLC in an intimately dynamic sense proved tricky, but what stands out about the mid-size SUV from Affalterbach is how much its ability in cornering belies its size.

The rear-wheel steering makes a big difference for the otherwise sizeable SUV, and even though the it weighs 1976kg (53kg more than before; the Coupe is 94kg heavier than before at 1998kg), the 4MATIC all-wheel drive keeps the GLC’s purchase on the road in check.

Suspension is relatively stiff for a family SUV even in Comfort, though adjustable, as one of the many aspects able to be customised through the multimedia screen menu or even steering wheel dials.

Steering itself can be adjusted, though is probably fine to leave in Comfort depending on personal preference.

But the hero of this - and any - AMG is the engine, and the M139 works surprisingly well in the big GLC.

Where it turns the A-Class hatchback into a proper supercar fighter, it makes the GLC a relatively muscular yet responsive family hauler.

The 310kW and 500Nm outputs are probably the sweet spot in terms of the GLC43 not feeling like there’s too much for anyone to handle, while still being quick enough to keep a keen driver happy.

On calmer roads, highways and gentle winding country roads, the GLC is comfortable enough with everything set up in the appropriate drive mode, though don’t expect to feel immensely refreshed after hours behind the wheel - it’s still set up for relatively dynamic driving.

Noise and road surface imperfections make their way into the cabin to some extent, though it’s not egregious, while one of the cars on test had a small creaking sound present in the dash, set off by road bumps and corners.

If you’ve driven any kind of XC40 or even a Polestar 2 before, the C40 will offer no surprises. It’s pretty much exactly the same from behind the wheel with a few subtle tweaks.

This is a very good thing. The C40 is quiet, easy to drive, and its electric motor and regen system offer a smooth single-pedal experience.

It is also alarmingly, overwhelmingly, rapid. While its massive set of batteries under the floor make it feel heavy off the line in stop-start traffic, sticking your boot into the accelerator will remove any doubt, particularly in the dual-motor variant, that this Volvo means business.

The dual-motor also has an incredible torque-vectoring system, making it extremely difficult to elicit so much as a squeak from its tyres. It also feels as though torque is distributed quite evenly between its two driven axles, making it feel neither prone to over- or understeer.

This has the effect of making the C40 feel somewhat indestructible in the corners, with absurd levels of grip. 

The same feeling is present in top-spec versions of the Polestar 2, only the feeling of ever-present weight is more noticeable in the higher-riding C40, which can make it unsettling to take corners at the kinds of speeds it is capable of.

The steering tune is interesting. Volvo offers two software-controlled modes, either heavy or standard, and the standard mode is heavy enough. 

Despite its electrical assistance, the wheel does continue to offer some organic feedback, making the C40 a pleasure to steer on countryside roads.

The ride is also surprisingly good, despite massive wheel options. I was impressed how easily the C40 handled most bumps and undulations, communicating little to the cabin. 

The ride can approach its limits with such big wheels and the weight of its batteries, generally these are communicated via unsettling thuds from underneath the car. Regular undulations at higher speeds also had the C40 bouncing around a little.

On the whole, though, the cabin is kept relatively insulated and serene, adding an element of total confidence, similar to that offered by Teslas, whilst offering better ride quality with a softer edge. At higher speed, at least on the 20-inch wheels, road noise does pick up, however.

In terms of electric driving, there is a single adjustable setting for regen. The car either offers a full single pedal mode with maximum regenerative braking to bring the car to a halt with the motor alone, or a ‘standard’ mode which tones the regen down and offers it blended in via the brake pedal. 

Single pedal mode is more efficient. I suggest you stick to it if you want to make the most of this car’s efficiency.

I was surprised to have so few complaints about the C40’s drive experience. This is a balanced and capable EV which is yet another example of how even vehicles which use combustion platforms are improved out of sight by full electrification.

Sticking to its brand promise, Volvo offers the full range of active safety equipment on the C40 regardless of variant.

This includes freeway-speed auto emergency braking, rear auto braking, lane keep assist with lane departure warning, blind spot monitoring with rear cross-traffic alert, and one of the best adaptive cruise control systems on the market.

The only item the single motor misses out on is a 360-degree parking camera, which is exclusive to the dual motor variant.

It is notable how the adaptive cruise control, blind spot monitoring rear cross-traffic alert, and rear auto braking are on the options list for the Polestar 2.

These active systems combined with eight airbags (the standard dual front, side, and curtain, as well as a driver’s knee and centre airbag) make for a five-star ANCAP safety rating to the latest 2022 standards.

Mercedes-Benz Australia’s warranty is a relatively standard five-year/unlimited kilometre offering, level with rivals like BMW.

Servicing intervals are every 25,000km or 12 months, whichever comes first.

Mercedes’ servicing costs can be covered in packs and for the first three services of a GLC43 SUV it will cost $3445, four for $4552 or five for $6935. These prices are as listed in December 2023, and are subject to change.

The C40 is covered by Volvo’s five year and unlimited kilometre warranty, with a separate eight-year, 160,000km warranty for the battery. There is also eight years of roadside assistance attached.

It is pleasing to see the service intervals for the C40 are long, as they should be for an electric car with so few moving parts, set at two years or 30,000km. 

The first 24 month service is free of charge, and Volvo tells us service pricing after this period will average out to around $100 a year ($200 per visit).
