Mercedes-Benz GLC300 vs Jeep Avenger

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.

The Jeep Avenger is a strong move for the brand as a city-focused offering, and particularly as its first EV.

The styling and easy driving experience should be a draw, but its price in an increasingly competitive small SUV (and electric car) market could be a turn-off for some - even if it is only few thousand dollars more expensive than the slightly larger Compass.

Despite a couple of small flaws and a lacklustre safety rating overseas, the Avenger is ultimately one of the best-driving cars the brand has put out in years, and deserves a look if you’re keen on a practical but stylish EV.

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.

One of the Avenger's biggest draws for me is its style.

Those who like the Jeep brand for its rugged off-road vibes, but don’t actually want or need to go off-road might enjoy that it still looks very Jeep.

We’re told that the decisions made in this car’s design are all for a purpose, and some of them are very clear.

For a start there’s a deliberate plastic barrier wrapped around the full 360 degrees of Avenger to protect the paintwork and body panels in low-speed collisions that can be just as likely off-road as in a carpark.

There’s also the sunken headlights, which sit far enough back that they’re less likely to be damaged in an impact, being one of the most expensive and breakable parts at the front of a car.

But there’s also a series of little hidden ‘easter eggs’ that the Avenger’s head designer Daniele Calonaci left up to us to find for ourselves.

For a start, the tail-lights feature an ‘X’ shape that’s inspired by the jerry cans used to carry spare fuel and liquids in World War 2.

The ‘X’ theme continues in other places on the Avenger,  though there are some more cutesy design features like a series of seven-slot grille motifs around the car in places like the wheels, tail-light, and even a small one under the front grille.

There’s a 3D ladybug in the roof rail up top, too. But perhaps the most ‘aww’-inspiring is the silhouette of a child looking through a telescope in the lower passenger side of the windshield, up at some stars in the upper driver’s side. The child? That’s Calonaci’s son.

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.

The outside of the Avenger is plenty of fun, but the inside is a fairly sensible place.

That’s not to say it’s boring, but the use of space for a car of this size is impressive, and there are plenty of places to store things.

There’s a well thought out phone charging pad in a relatively deep storage compartment in the centre of the Avenger, as well as the cupholders in front of the centre armrest and another storage bin underneath, plus a ‘shelf’ along the dash.

The amount of storage is impressive given the Avenger’s interior is a nice, tidy design that still manages to incorporate some useful elements some cars forgo - buttons for the climate controls, for example, are something that are increasingly (and frustratingly) rare.

Anyone who has used a Uconnect system in a Jeep or Fiat in the past might like to know that this one (accessible via a 10.25-inch touchscreen) is a step-up from predecessors.

It’s not perfect, some elements of the menu and feature placement seem a little random at first, but it doesn’t lag, is easy to connect to wirelessly, and has a fairly helpful voice control system.

Functionality is most of the way there generally, but a few missing things like dual-zone climate control or electric adjustment for the passenger seat feel like let-downs, plus the heating on the front seats seemed to be quite weak for a long time before eventually warming.

Behind those seats, the second row is lacking just about any amenities besides a USB port, but it’s not too cramped for a light SUV. Adults might find it suitable for relatively short trips, but kids should be fine for a while.

The sunroof (when featured) doesn’t extend very far back, so the second row also feels a little dark.

Behind that, an impressive 355 litres of boot space expands to 1250 litres when the seats are folded down, plus a plastic lining on the boot lip means you don’t scratch the car when loading or unloading.

Before the Avenger had even landed, Jeep announced a $3000 reduction to the original pricing. While it might seem like this move stems from an increasingly competitive small-SUV market, Jeep says production costs dropped after the pricing was initially set, and the decision was made to pass it along to customers.

In any case, the Avenger now starts from $49,990 before on-road costs for the entry-level Longitude, with a mid-spec Limited costing $54,990 and the appropriately named Summit set at $60,990.

This puts the Avenger among the most expensive offerings in the 'Light SUV' category along with the electric Mini Aceman (from $55,990) and hybrid Lexus LBX (from $47,550), but around the same price as the slightly larger Hyundai Kona Electric (from $54,000) and Renault Megane E-Tech (from $54,990).

It also looks like brilliant value compared to the much smaller and lower-ranged Fiat 500e (from $52,500). Style comes at a cost.

For the Avenger, there’s a bunch of kit that’s standard across the range, plus only one cost-option - premium paint at $990.

Each Avenger gets dual 10.25-inch screens inside, one for the driver instrument display and the other a touchscreen for the multimedia controls, centred on the dash so it can be reached by both front occupants.

Satellite navigation, keyless start, adaptive cruise control and Jeep’s Selec-terrain drive mode system are all also standard features.

The Limited adds partial synthetic leather trim to the seats, keyless entry, more safety features like blind-spot assist and parking sensors, plus a height-adjustable boot floor and more powerful AC charger, with an 11kW version replacing the 7kW of the Longitude. The Limited also has optional two-tone roof paint in black for $495.

Climbing to the Summit means you get the two-tone roof as standard, plus LED projector headlights and LED tail-lights, 18-inch alloys, leather accented heated seats with power adjustment and lumbar massage for the driver, plus it also gets a sunroof over the front occupants.

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 Avenger has one drivetrain for now, a front-wheel drive electric motor, though it sounds like we shouldn’t rule out the possibility of other petrol hybrid drivetrains in the future.

The EV Avenger we’ve got is built on a 400-volt electric architecture, with a single motor delivering 115kW of power and 260Nm of torque.

It’s got a a mode that increases the regenerative braking, though isn’t quite a one-pedal driving experience.

Jeep says it’ll hit 100km/h in 9.0-seconds, but apparently tops out at 150km/h.

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.

The Avenger has a reasonably sized 54kWh lithium-ion battery for a light SUV, which it says allows for a driving range of up to 396km, or 390km in the top-of-the-range Summit, due to the specification.

Under WLTP testing, Jeep says the Avenger is rated at 15.4kWh/100km (15.8kWh/100km for the Summit) for efficiency, and it comes with a Type 2 CCS combo charging socket for either DC fast charging up to 100kW, or AC charging up to 7kW in base Longitude and 11kW in higher variants.

On DC charging at its max 100kW rate, the Avenger should take about 24 minutes to charge from 20 to 80 per cent, while slower AC charging at 11kW takes five hours and 34 minutes.

On the launch drive route, we were seeing between 14.8 and 16.4kWh/100km on the trip computer, so Jeep’s claims seem accurate.

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. 

The mix of a fun exterior and practical interior for the Jeep seem to blend into the Avenger’s driving experience. It doesn’t feel too much like an EV, but it is still playful and capable on the road.

Jeep wanted the Avenger to come across like a normal car that just happens to be electric, and the relatively calm take-off (rather than the usual immediate torque push electric cars are capable of) seems to prove that.

Though 115kW doesn’t sound like much on paper, it feels brisk enough for what the little Jeep is built for, and its delivery means even on a wet day like what we copped during the launch drive, wheelspin and torque steer were minimal.

Once up to speed, the Avenger feels pretty light for an EV, and it’s playful enough in corners without feeling like it’s becoming unstuck or hard to handle.

The suspension and steering are clearly aiming for comfortable driving more than sporty performance, and so while both feel well-sorted, neither are particularly communicative. But the steering is accurate and feels nice and light, making the Avenger easy to point into a corner and you can trust it to hold on.

Perhaps the biggest downside is the brake pedal, which is soft and doesn’t grab as quickly or progressively as you’d expect. It takes a few presses to work out how much pressure you need to stop the car.

But a drive mode that adds a bit of regenerative braking helps out there, even if it’s not proper single-pedal driving.

At higher speeds, the Avenger settles well over big bumps and undulations, feels comfy on most surfaces, and despite a bit of road noise and a small rattle in the dash on one of our test cars, it feels pretty easy and confidence-inspiring.

Jeep says the Avenger is built to handle some light off-road driving but I imagine its front-wheel-drive setup would be limiting in some circumstances, especially in the rainy, muddy weather we faced. Despite that, some unsealed mud and gravel driving proved the Avenger capable of gentle inclines at low speeds without risk of sliding.

For reference, ground clearance is 200mm, while the approach and departure angles are 20 and 32 degrees, respectively.

The Jeep Avenger hasn’t been tested by ANCAP, but comes with a disappointing three-star score from Euro NCAP.

Jeep Australia says it’s currently working with ANCAP regarding a potential local score, but wouldn’t detail what that could mean. A small SUV’s score dropping below four stars might concern some young family-type buyers, though most of its poor scoring comes in the categories of Vulnerable Road Users (pedestrians and cyclists) and Safety Assist (active tech).

In terms of what the Avenger offers as standard, there’s auto emergency braking (AEB), lane-keep assist, traffic sign recognition, driver monitoring, a reversing camera and six airbags (no front-centre bag, though).

It’s notably missing rear-cross traffic alert, and the base Longitude makes do with regular adaptive cruise control and parking sensors at the rear only, while higher variants get blind-spot assist, surround parking sensors, and intelligent cruise control.

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.

Jeep offers a five-year/100,000km warranty, which is starting to be overtaken by other brands increasingly offering seven-year/unlimited kilometre warranties or longer.

The high-voltage battery system of the Avenger is, however, covered for eight years or 160,000km, whichever comes first.

Jeep also offers capped-price servicing for the five-year warranty, with scheduled visits costing just $250 and spaced out at 12,500km or 12-month intervals.

There’s also the brand’s lifetime roadside assist, but only when you service your car with Jeep.
