Porsche Macan vs Mercedes-Benz GLC300

What's the difference?

There is no doubting the substance of the Porsche Macan Electric. Its ride, steering and poise make it a joy to drive on twisting roads, and it ticks the practicality boxes, too.

The only lingering question is whether enough people are ready to make the all-electric switch. Only then will we know if Porsche's Macan gamble has paid off.

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 Macan Electric looks sharp, all aerodynamic and swept-back like a range-maximising electric SUV should.

There’s functional method behind all this swoopy styling, too. The headlights look as though they’ve been chiselled into the body work, and at the grille, you’ll find active venting to help with cooling when needed.

There is also a sizeable front splitter that looks very much like the Macan is sticking its jaw out. All of which is to assist with aero and range.

It’s also a dual charging port layout with access left and right, though the latter is AC charging only, while the one on the left does both.

Step inside the Macan and you’ll find a familiar and very welcoming space. I especially like the twin-screen set-up that looks great in the way it's kind of embedded into the dash. Each is big, clear and easy to use.

I also really like the control panel that gives you quick-button access to the climate control, and the haptic feedback is next level, with the whole screen clicking in or out whenever you hit a button.

That said, in Turbo-guise you’re dropping almost $200,000, and some of the materials feel too hard and plasticky at that price point.

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 is a little open-sesame magic at play with the Macan, and that starts at the frunk, where, if you lovingly caress the bonnet, it will automatically pop open for you, revealing an 84-litre storage space.

Rubbing the charging port will see it slide open, too, but just in case you’re not the kind of person who likes to fondle their car in public, you can use the key.

The Macan’s boot is a little more traditional, opening to reveal 540 litres (but just 480 litres in the 4S or Turbo) of storage with the rear seats in place, with a wide, flat and very useable area for your goodies.

The back seat of the Macan feels spacious enough, without being outstanding. There’s more than enough space for my 175cm frame, with enough knee and head room, but the way the middle console juts out will definitely eat into leg room for any middle-row passenger.

Elsewhere you get air-con controls with vents, along with bottle storage in each of the doors. There is also a pull-down divider that’s home to two extra cupholders.

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.

Mercedes-Benz is offering Australia just the GLC300 grade in both the SUV and Coupe body styles.

High-performance AMG variants are out overseas now and will arrive in Australia soon, too.

You can expect to pay more for these AMG beasts - a lot more than the $113,900 list price of the GLC300 Coupe.

Still the GLC300 Coupe does come standard with an AMG Line body kit and 20-inch AMG alloy wheels. LED headlights are also standard, so is the panoramic glass roof, tinted rear glass, proximity unlocking and a power tailgate.

Inside there’s synthetic leather Artico upholstery, sports heated front seats, Nappa leather steering wheel, an 11.9-inch media display with Apple CarPlay and Android Auto, a 12.3-inch digital instrument cluster and a head-up display. There’s also dual-zone climate control and wireless phone charging.

The value is good in terms of features, although the price is slightly higher compared to the rivals such as the BMW X4 xDrive30i ($106,400) and Audi Q5 Sportback 55TFSI ($110,200).

It’s worth pointing out, too, that the GLC300 Coupe is about $10K more than the GLC300 SUV version. Why? The coupe versions of prestige SUVs always tend to be pricier than their regular more boxy SUV siblings. Somebody in marketing will be able to explain why.

Having lived with the GLC300 Coupe with my family over the past few days I can say the proximity unlocking which works by touching even the back door handles is excellent, the tinted windows are dark and cut out much of the sun's glare, but there’s no climate control in the second row. There are air vents back there, which is good.

I found that on hot days the semi-transparent shade on the glass roof couldn’t stop the cabin from heating up quickly.

The entry-level Macan is equipped with a single rear-mounted electric motor, and it will make a total 250kW (265kW with launch control activated) and 563Nm, which is enough to push the cheapest Macan to 100km/h in 5.7 seconds.

The 4 then adds a second electric motor for AWD, upping the grunt to 285kW (300kW with the launch function) and 650Nm, and drops the sprint to a brisk 5.2 seconds.

The 4S is probably the performance sweet spot, with its dual-motor set-up generating 330kW (380kW in launch) and 820Nm, and a blistering sprint of just 4.1 seconds.

But the Macan Turbo is a true monster. We’re talking 430kW (470kW with launch control), 1130Nm and a sprint to 100km/h that’s as fast as a Carrera Cup race car – just 3.3 seconds.

It’s twin-motor, all-wheel drive and offers the kind of brutal acceleration that gives you a little facelift every time you step on the accelerator.

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.

Every Macan is fitted with a big 100kWh lithium-ion battery, which helps deliver a solid driving range no matter which one you choose.

The entry-level Macan will cover the most distance, at a claimed 654km, while the 4, 4S and Turbo will travel 624km, 619km and 616km, respectively.

The Macan rides on an 800V architecture, and is set up for 270kW DC high-speed charging, which will take 21min to go from 10 to 80 per cent. It will also accept 11kW AC charging, which should take 10 hours to go from empty to full.

Worth noting, though, that most home wall boxes are around 7.0kW, which means a full charge would take more like 13 hours plus.

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.

Porsche seemed at pains to prove that, though the all-electric Macan has lost its ICE heart, it's still worthy of the badge, and still very much a Porsche.

First stop, then, was the Norwell race circuit in Queensland, to put the Macan through its paces with 0-100km/h sprints, drifting (well drift attempts... ) on a watered-down skid pan and finally some high-speed running on the circuit.

And two things immediately became very clear. The first, and most obvious, was that, like the first men on the moon, we were likely among only a handful of people that might ever take their all-electric Porsche mid-size SUV to a race track. And second, this is one seriously sorted electric car.

Happily, for the many (read: every) owners who won't be pulling out of a pit garage at their next local track day, the Macan is actually more enjoyable on the road than it is on the track.

On the latter, there's a freedom to push too hard – what with the lack of trees, guard rails or oncoming traffic – and cracks do appear, mostly from the screaming tyres struggling with the two-tonne-plus weight.

But on public roads, where a thick fog of consequence prevents you pushing too hard, the Macan is a gem.

Porsche tends to have a knack for these things, I know, but the Macan is a seriously smooth and satisfying drive.

The ride is bang-on (comfortable enough on rougher surfaces, firm and grippy enough on twisting roads) and the steering is direct and confidence-inspiring.

Body-roll has been largely banished, too, with the Macan staying flat, stable and satisfying, even on the tighter stuff.

In much the same way the ICE Macan defined what it meant to be a driver's SUV, I think this one does the same in the EV space. And the fact that it does it with five seats and a decent boot is a sizeable bonus.

But there's no denying it lacks in the emotion department. That sense of excitement, the sound track, the hard-to-define fizz – as competent its this, and as weaponised as the EV powertrain is – it does feel a little clinical, like a tool doing its job and doing it well.

One important caveat. We've driven the 4 and Turbo to date. The entry-level Macan and the mid-tier 4S are still incoming. And I suspect I wouldn't be dropping my deposit on the Turbo.

Yes, the power is ridiculous, but I don't reckon you need it. For me, the 4 is more than enough, but I suspect the real performance sweet spot will be with the 4S.

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 GLC was given the maximum five star ANCAP rating in 2022. There’s AEB, active lane keeping assistance and active blind spot warning and nine airbags including a centre airbag.

As mentioned above I especially liked the surround-view camera systems - which let you look right around the car - good for driveway safety and kids.

For child seats you’ll find two ISOFIX mounts and three top tether anchor points in the second row.

I was also impressed to see a space-saver spare wheel under the boot floor and not just a puncture repair kit. 

The Porsche ownership experience is frankly underwhelming by modern standards, with the brand offering just a three-year/unlimited kilometre warranty, plus an eight-year/160,000km battery warranty.

The positive, though, is that servicing should only be required every two years or 30,000km. You also buy a prepaid service plan for three, four or five years, priced at $1495, $2795, $2995.

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.
