Mercedes-Benz GLC-Class vs Hyundai Santa Fe

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 Santa Fe Hybrid is a better Santa Fe to drive than the V6 petrol or the diesel variant. It’s also a lot more fuel efficient, but the value isn’t as great at this price. Also keep in mind that the Hybrid has a much lower braked towing capacity relative to the diesel and V6 petrol Santa Fes.

The Elite grade will save you money, and you’re not missing out on many luxuries.

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.

There’s only one way to tell the hybrid version of the Santa Fe from the petrol and diesel variants - the wheels. The hybrid's wheels are smaller and have a sort of ‘cog’ design to them. I’m not a fan of the styling, but they’re supposed to be aerodynamic and save fuel.

Overall, I am a fan of the Santa Fe’s looks which were given a major change in 2020 with a completely different grille and interior.

I like the way Hyundai has moved away from giving all its cars the same face, with each model now having its own visual identity.

The Santa Fe’s wide, cat fish-like gaping mouth grille might not be for everybody, but it sure doesn’t look like the front of any other SUV on the market.

The rear of the Santa Fe is far more conservative but looks prestigious enough to stop short of the boredom threshold.

It’s far from boring inside with the dash sculptured into what appear to be rock pools, with geyser-like air vents and a floating centre console.

Again, no sign this is a hybrid in the cabin either, which is the way it should be, or will be when electric vehicles become the norm.

The cabins of the Elite and Highlander are filled with leather and modern tech. It’s a plush place made even plusher on the Highlander with its Nappa leather upholstery.

The Santa Fe is a big, mid-sized SUV at 4.8m end-to-end, but it’s not as large as a Hyundai Palisade. That's huge at five metres long.

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 Santa Fe is among only a handful of mid-sized SUVs offering seven seats. The third-row seats are really designed to be used occasionally. They’re flat and fairly hard and the passengers back there aren’t fully covered by the side curtain airbags.

The second row offers plenty of room. Enough, even for me at 191cm, to sit comfortably behind my driving position.

And if you’d like more space then the Highlander grade allows you can replace that bench seat with two captain’s chairs in the six-seat version.

Clever cabin storage spaces can be found throughout. I particularly like the floating centre console with an area underneath big enough for a small backpack, and the shelf above the glove box in the dash is also good for throwing a wallet or phone.  

Big door pockets, cupholders and a deep centre console storage box are also on board.

For charging devices there are five USB ports (two up front, two in the second row, and one in the third), two 12-volt outlets (front seats and cargo area) and a wireless phone charger.

While there isn’t three-zone climate control. There are directional air vents in all three rows and the Elite and Highlander grades also come with pull-up sun shades for the rear windows.

As for the boot, most of the time you’ll probably have the third-row seats folded flat, and that’ll give you a cargo capacity of 571 litres.

Or, if you are using the third row there’s 130 litres of space left for you to use.

Hybrids cost more than their petrol and diesel equivalents, but how much more depends on whatever the car manufacturer decides you should pay. 

Hyundai is charging $6500 extra for the Santa Fe hybrid over the petrol version and $3000 more than the diesel. 

Also, for now, you can only get the Hybrid on the Elite and Highlander grades, the two most expensive levels in the Santa Fe line-up.

This means you’ll pay a list price of $63,000 for the Santa Fe Elite Hybrid and $69,550 for the Highlander Hybrid.

The standard features for the Elite Hybrid and Highlander hybrid are exactly the same as their petrol and diesel equivalents, except for the wheels. The hybrids have smaller 19-inch wheels (they’re 20-inch alloys on the regular Santa Fe) that Hyundai says are designed to be more aerodynamic.

So, along with those futuristic wheels, also coming standard on the Elite Hybrid are LED headlights and tail-lights, a gesture tailgate, privacy glass, proximity key with push-button start, a 10.25-inch media display, 12.3-inch instrument cluster, 10-speaker Harman Kardon stereo, leather upholstery, heated front seats with a power driver’s seat, dual-zone climate control, a wireless charger, sat nav, plus Apple CarPlay and Android Auto.

The Highlander Hybrid has all of that, but adds Nappa leather upholstery, a power front passenger seat, ventilated front seats and heated window seats in the second row, a head-up display and a panoramic sunroof.

The Elite and Highlander are both seven seaters, but you can ask for six seats in the Highlander and have that second row bench seat replaced with two captain’s chairs.

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 Santa Fe Hybrid is not a plug-in hybrid like the Mitsubishi Outlander or Kia Sorento. That means you don’t need to connect the battery to a power outlet to charge it. Instead, the battery charges on the go as you drive it, and through regenerative braking.

Under the bonnet is a 1.6-litre, four-cylinder, turbo-petrol engine and an electric motor. They have a combined output of 169kW/350Nm.

That’s pretty good grunt. Just as a comparison, the V6 makes 200kW/331Nm, while the diesel engine produces 148kW/440Nm.

If you’re planning on towing, then the diesel and petrol are clearly the better choices with their 2500kg braked towing capacity, compared to the hybrid’s 1650kg.

The Hybrid Santa Fe is also all-wheel drive and a six-speed automatic transmission shifts gears smoothly.

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.

This is what it’s all about isn’t it? How much fuel does the Santa Fe Hybrid use? 

Hyundai says this hybrid will use 6.0L/100km after a combination of open roads and urban driving. That is excellent, but if this was a plug-in hybrid (PHEV) that figure could be as low as 4.0L/100km.

Still, the Santa Fe hybrid is much more fuel efficient than the V6 variant which uses 10.5L/100km.

I took a look at the drive history of the Santa Fe Hybrid I tested at the end of the Australian launch.

According to the trip computer the car had travelled 967.2km and had used an average of 7.3L/100km.

About 500 of those kilometres were done by me with peak hour city traffic, country roads and motorways all in there. That’s great fuel efficiency, but a Santa Fe PHEV would do better.

As I said earlier, there’s no need to plug the Santa Fe into an external power supply to charge its lithium-ion battery, it’ll charge itself automatically through normal driving.

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. 

You’re not just getting better fuel economy in the hybrid version of the Santa Fe, you’re getting a better SUV to drive. 

That’s what I found when I tested the Santa Fe Hybrid at its Australian launch. The ride is more comfortable and the steering feels more responsive and lighter than the V6 petrol or diesel Santa Fe, both of which I’ve driven extensively.

The better ride I think comes down to the stabilising effect of extra weight situated low from the batteries (they’re located under the driver). Hyundai told me the front suspension had been revised to deal with the added weight, too.

So, I feel the ride is now more comfortable, less jittery with a smidge more planted feeling to the handling.

The lighter and better steering feel may have something to do with having a smaller engine in the nose of the Santa Fe. The 1.6-litre four-cylinder weighs less than the 2.2-litre diesel engine and the V6 petrol. That lighter font end now has a more ‘pointable’ feeling.

That said, the electric motor would add more weight to the Santa Fe hybrid’s nose, too.

Another difference to the way the hybrid drives is the take-off acceleration. It’s quite sudden and forceful for a family SUV in this class and that’s due to the 350Nm of torque, available from 1000rpm.

That’s great for moving away out of a car space and quickly blending into traffic, or accelerating away from traffic lights.

Visibility as with the regular Santa Fe is excellent and parking is easy, too, given this isn’t a large SUV.  

The regular Santa Fe scored the maximum five-star ANCAP rating when it was tested in 2018. You don’t need me to tell you the world was a different place back then, as it was in terms of automotive safety requirements.

New advanced safety tech has been added to this SUV over the years and this Santa Fe hybrid comes equipped with all of it, too. 

There’s AEB which works at intersections, too, blind-spot warning, rear cross-traffic alert, lane keeping assistance, rear occupant alert, auto high beam headlights and adaptive cruise control.

The forward AEB will bring the vehicle to a complete stop for cyclists and pedestrians at speeds between 10km/h and 65km/h or 75km/h for vehicles.

Above the speeds the vehicle will slow as much as possible in an attempt to avoid a collision.

The Highlander adds even more tech in the form of a surround view camera, blind spot monitor, and rear AEB. 

This top grade also boasts remote parking that allows the you to drive the Santa Fe in or out of tight parking spots using the key fob as a remote control. It sounds incredible but it’s real. I’ve demonstrated this feature in the video above.

On a super serious note be aware that even though this is a three-row SUV, the curtain airbags don’t completely cover the third row windows.

The Santa Fe isn’t the only SUV with this airbag inadequacy - the Kia Sorento has the same problem.

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 Santa Fe Hybrid has the same warranty as the rest of the range at five years/unlimited km. The battery is covered by an eight-year/160,000km warranty, which is pretty standard for hybrids.

Servicing is required every 10,000km/12months, however, the costs were yet to be finalised at the time of publishing.
