Mercedes-Benz GLC300 vs Gac Aion V

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.

Candidly, I questioned the logic behind GAC entering the Australian market, especially now given the seemingly non-stop influx of other brands. How could it really hope to stand a chance against so many similarly priced and similarly equipped rivals?

Well, the answer is by providing a better product. The Aion V is simply a better package than many of its rivals, Chinese and otherwise, at least based on our initial impressions.

It combines value and practicality but also adds a level of driving comfort and manners its Chinese rivals can’t match.

Is that enough to guarantee success? Not at all, but it’s a strong foundation to start with and at least gives GAC a fighting chance to not get lost in the crowd.

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 most notable elements of the Aion V design is the absence of a ‘GAC’ badge on the front. That’s because, while all GAC models in Australia will be sold under the one name, in its native China there are several different sub-brands. GAC Aion is the ‘new energy vehicles’ brand, focused on electric vehicles (EVs), while the smaller Emzoom SUV is part of the more mainstream Trumpchi brand that offers internal combustion engine models.

It means the three cars sold initially, and even as the brand moves forward with its expansion plans, there will likely be stark visual differences between models because they are effectively different brands. In the same way Holden ended up with a mixture of Opel, Chevrolet and GMC products in its final years.

Having said all that, the Aion V itself is an inoffensive design. It’s not as generic as some of its rivals, with some design character around the headlights and silhouette, so overall it cuts a likeable figure without being particularly memorable.

Like so many modern cars, the Aion V has a very simplistic layout inside, with more screens and less physical buttons and switches to reduce cost and complexity. There’s an 8.8-inch digital instrument display and a 14.6-inch multimedia touchscreen in the centre on the dashboard.

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.

In terms of practicality there’s a handy space for a wireless smartphone charging pad, and that previously mentioned heated or cooled centre console box. Oddly, though, there is no traditional glove box. Instead there are just a pair of bag hooks ahead of the front seat passenger.

Space is good for a mid-size SUV, with a roomy front and respectable space in the second row. It would comfortably accommodate four adults, so would be a good option for families with older children.

As for the boot, it’s a generous 427 litres and has multiple adjustable floor heights available. Disappointingly, even though it has space for a spare, potentially even a full-size one, it only has a tyre repair kit. That might be fine in some markets around the world, but in the vastness of Australia, that is not the best option. Even a space-saver spare would be a better bet.

Starting with the basics, the Aion V is a five-seat electric SUV priced from just $42,590, before on-road costs, for the entry-level model.

Now, not too long ago an all-electric SUV for under $45K would be a revelation and would have made an impact on this market. But there are plenty of alternatives to choose from these days at similar money, including the Geely, Leapmotor and the BYD Atto 3.

Even so, at $42,590 for the entry-level Premium and $44,590 BOC for the more-premium-than-Premium Luxury variant, that’s still very competitive pricing.

For that money you get a well-appointed mid-size SUV, with even the base model equipped with LED headlights and tail-lights, 19-inch alloy wheels, a panoramic sunroof, heated and ventilated front seats, dual-zone climate control and a nine-speaker stereo.

Stepping up to the Luxury adds partial genuine leather seats, massaging front seats and a box in the centre console that can act as a fridge and a warmer, depending on your needs.

While neither the cheapest EV nor the best-appointed, the Aion V does a nice job of offering a compelling value proposition in its competitive set.

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.

Both the Aion V Premium and Luxury are powered by a 150kW/210Nm electric motor, which drives the front wheels. 

Aion doesn’t claim a 0-100km/h time, but it wouldn’t be quick, at least not in EV terms. If you’re looking for a ludicrously powerful electric car - this ain’t it. It’s a perfectly fine powertrain for the job at hand, but it won’t blow your socks off with its performance and will take more than eight seconds to run 0-100km/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 battery is 75.2kWh lithium-phosphate type, which provides a claimed range of 510km. Importantly, that figure is on the WLTP cycle, not the more lenient Chinese (CLTC) test protocol, so you could reasonably expect close to that target in the real world.

GAC claims it can accept up to 180kW charging speeds, which will get the battery from 10-80 per cent in just 24 minutes. 

It also has vehicle-to-load functionality, so you can draw power from the battery for tools or appliances if you need it.

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. 

This is perhaps the area where the Aion V surprised the most. One of the most consistent qualities of these new Chinese-developed models is their incompatibility with Australia’s unique road conditions. They have a tendency to lack comfortable, controlled suspension and well-weighted and consistent steering.

That’s not the case with the Aion V, with GAC clearly taking the benefits from the partnerships it has with Toyota and Honda to learn what international markets prefer. Is this a clear standout, class-leading SUV dynamically? No. But it is above-average in the way it rides and handles.

The suspension is well resolved and feels comfortable to live with, while the steering is nice and direct, which will make navigating the cities, suburbs and open roads more easy and enjoyable. 

There is still some fine-tuning that could make it better, but overall the Aion V leaves a positive first impression. 

GAC is offering the same safety equipment across both models, which is a nice touch to avoid any need to compromise.

This includes full airbag protection for all occupants, front and rear parking sensors and a 360-degree camera system. 

There’s also a lengthy list of driver assistance features, including adaptive cruise control, autonomous emergency braking, forward collision warning, traffic sign recognition, emergency lane keeping assist, rear cross-traffic alert and door opening warning.

These systems could benefit from some real-world testing and calibration, because while better than some, they were still intrusive and annoying at times - most notably the driver attention monitoring.

ANCAP has not yet tested the Aion V, but it has received a maximum five-star rating from Euro NCAP, which typically carries over to the local body.

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 Aion V is covered by an eight-year, unlimited kilometre warranty which is well ahead of the mainstream pack, typically sitting at five years, unlimited km. The drive battery is also covered for eight years, 200,000km and roadside assist is included for five years. Recommended service interval and costs are still to be confirmed.

But one of the biggest challenges for all these new car brands is finding space in the Australian market - literally. If you want to sell a lot of new cars you need a lot of new car showrooms and if you want to keep customers happy, you’ll need enough service centres to keep cars on the road as much as possible.

GAC has plans to have as many as 100 dealerships in the next five years, but right now it has reportedly less than a dozen. That will make servicing problematic if you do not live in close proximity to a service centre. This isn’t the work of a moment either, with so many new brands fighting for dealership real estate and staff there are only so many places GAC can set up shop.
