Porsche Macan vs Mercedes-Benz GLC-Class

What's the difference?

Competent and comfortable, the Macan T delivers that amazing Porsche double act of crisp dynamic response without compromising refinement. It’s well equipped for the price, neatly packaged, and entertaining to drive. But there are holes in its armour. Active safety comes up well short and a three-year warranty now stands out like a sore thumb. It’s good, but could be better.

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.

Michael Mauer has been Porsche’s chief of design for close to 20 years, overseeing the look and feel of every product the brand has produced in that time. And he’s been successful in massaging particular forms and signature elements to work across the line-up. 

For example, you can see more than a hint of 911 in the Macan T (and other models, for that matter), from the elongated four point headlights, to the gentle curve at the rear of the roofline, as well the distinctive tail-light treatment.

Since launching internationally in 2012, the Macan has been tweaked in 2016, before a full-blown refresh in 2021. Mauer and his team have somehow transplanted a Porsche sports car’s stance and personality to this mid-size SUV, which incidentally boasts a drag-coefficient of 0.35 (not bad, but still a fair way off the 911’s 0.29). 

For car-spotters keen to tick the Macan T off their list, the thing to look out for is exterior elements finished in ‘Agate Grey Metallic’. Specifically, the middle section of the front apron, the side ‘blades’ running across the lower section of the doors, the roof spoiler, and the exterior mirrors (including their V-shaped bases).

Then it’s all about high-gloss black on the side window trims, exhaust outlets and parts of the rear diffuser. But the biggest giveaway is the Porsche logo and model designation finished in, you guessed it… Agate Grey Metallic.

In looking at the Macan T’s interior design it’s important to call out our test car’s optional leather trim package ($3280) and carbon interior trim package ($1600), combining to dial up the cabin’s racy, premium feel.

A relatively simple dash design incorporates Porsche’s iconic three-dial instrument layout housed in a compact, curved binnacle. On the right-hand side a 4.8-inch configurable info display takes the place of what would have traditionally been an analogue gauge.

The wide centre stack houses a 10.9-inch media display above (big tick) physical ventilation controls. A sloping centre console is filled with touch controls under a piano black finish. Looks good in the showroom, but fingerprints are its enemy.

The front sports seats feel as good as they look, and overall the design is premium, functional and focused.

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.

At just over 4.7m long, around 1.9m wide, and a fraction more than 1.6m tall the Macan is a large medium-size SUV, but inside it feels more like the former than the latter.

Plenty of breathing space for the driver and front passenger, with a broad centre console dividing the space. Storage is good, too.

The glove box is a handy size, there’s a decent lidded box between the seats (that doubles as a centre armrest), as well as two large cupholders in front of it, and a handy oddments tray just behind the gearshift. Big door bins with space for large bottles are also a welcome inclusion.

Swapping to the back seat, sitting behind the driver’s seat, set to my 183cm position, I had heaps of leg and headroom. There’s even enough room for three full-size adults on short to medium journeys, although the full road trip experience would be too close for long-distance comfort. A trio of up to teenage kids will be laughing. 

For storage there are two cupholders in the fold-down centre armrest, bins with enough room for large bottles (and a bit more) in the doors, and adjustable air vents with temperature control as part of the three-zone climate-control system. No map pockets on the front seat backs, though.

Power and connectivity runs to a 12-volt outlet in the front centre console and another in the boot, as well as a SIM and SD card slot in the front, supplemented by two USB-C jacks in the front and another pair in the rear. 

Speaking of the boot, it’s generous, with 488 litres (VDA) available with all seats up (measured to the upper edge of the rear seats). Fold the 40/20/40 split-folding rear seat and that number grows to 954 litres. Measure volume right up to the roof in that configuration and you have no less than 1503 litres to play with.

The boot space is properly illuminated, there are four tie-down anchors to help secure loose loads, and a small netted space lurks behind the wheel tub on the driver’s side.

Our test car was fitted with the optional adaptive air suspension system ($2790) which allows lowering of the car’s rear when stationary to make shuffling heavy loads into the back easier. And the standard auto tailgate is super helpful.

Maximum towing capacity for a braked trailer is 2.0 tonnes (towbar preparation and ‘Trailer Stability Management’ are standard), and the spare is a space-saver.

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 Macan T is powered by a version of the VW Group’s ‘EA888’ turbo-petrol, four-cylinder engine, used in a host of Audi, Seat and Skoda models, as well as, most-notably, the previous generation VW Golf Mk7 GTI.

The 2.0-litre, all-alloy unit uses a combination of port and direct fuel-injection, plus variable cam timing on the inlet and exhaust side to produce 195kW from 5000-6500rpm, and 400Nm across a broad plateau from 1800rpm right up to 4500rpm. The rev ceiling sits at 6800rpm.

Power goes to all four wheels via a seven-speed dual-clutch automatic transmission and an electronically-variable multi-plate clutch.

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.

Porsche’s official fuel economy number for the combined (ADR 81/02 - urban, extra-urban) cycle for the Macan T is 9.5L/100km, the 2.0-litre four emitting 217g/km of CO2 in the process.

Over a week of city, suburban, and some freeway running we saw a dash-indicated average of 10.2L/100km. A solid, if unspectacular result for a close to 1.9-tonne SUV. 

Auto start-stop is standard, but pricey 98 RON premium unleaded is required, and you’ll need 75 litres of it to fill the tank.

Using the official number that translates to a range of 789km, which drops to 750km using our real-world number.

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 claims the Macan T will accelerate from 0-100km/h in a suitably rapid 6.2 seconds and mid-range pulling power is healthy, with maximum torque available from 1800-4500rpm.

Worth noting, however, if you’re looking for ‘special event’ engine and exhaust noise to accompany that progress you may be left wanting more aural oomph. Despite our test car’s optional sports exhaust ($3080), this four-cylinder can’t match the relative drama of the Macan S and GTS’s twin-turbo V6.

The upside of that difference is the 2.9-litre V6 puts an extra 59kg on the Macan’s front axle, so the 2.0-litre T feels lighter and that bit more responsive when the road starts to twist.

Suspension is multi-link front, trapezoidal link rear, and the Macan T is also fitted with stiffer, model-specific sway bars to manage body roll. Ride height is also 15mm lower than the base 2.0L Macan.

Steering is quick, road feel is good, and despite the standard 20-inch rims, ride comfort is excellent. This is Porsche’s long-established, engineering party trick, combining plush compliance with sharp dynamic response, even in a high-riding SUV. That said, the optional adaptive air suspension fitted to our test example, is $2790 well spent.

The drivetrain is set up with a RWD bias, and standard rubber is Michelin’s high-performance SUV tyre, the Latitude Sport 3 (265/45 fr / 295/40 rr). They grip hard while remaining quiet, and the Macan T is an entertaining drive on a quiet B-road.  

Braking is by vented discs all around (350mm fr / 330mm rr) with beefy four-piston alloy monobloc fixed calipers up front and floating singles at the rear. Stopping power is reassuringly strong and progressive, especially important given the car’s 2.0-tonne (braked) towing capacity.

For more adventurous drivers, ground clearance is 187mm, while the approach, departure and ramp angles are a relatively modest 15.8, 15.4, and 21.0 degrees, respectively.

In the less challenging terrain of a shopping centre car park the standard reversing camera and 360-degree surround view make manoeuvring into tight spaces a stress-free operation.

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. 

Porsche is the last brand standing in the local mainstream sports luxury market, offering a three-year, unlimited kilometre warranty when the rest of the segment has moved on to five-year, unlimited km cover. 

The good news is paint is covered for three years and a 12-year (unlimited km) anti-corrosion warranty is included (the Macan’s body is fully galvanised). 

Porsche Roadside Assist provides 24/7/365 coverage for the life of the warranty, and after the warranty runs out is renewed for 12 months every time the vehicle is serviced at an authorised Porsche dealer.

Servicing is required every 12 months or 15,000km, which is less in terms of mileage than some others in the category.

With Porsche, final costs are determined at the dealer level (in line with variable labour rates by state/territory), but indicative pricing for the first five years is: 12 months/15,000km (annual) - $695, 24 months/30,000km (inspection) - $1300, 36 months/45,000km (annual) - $695, 48 months/60,000km (inspection) - $1300, 60 months/75,000km (annual) - $695. Not exactly cheap, but not outrageous in this part of the market.

A brake fluid flush is recommended every two years ($290), as well as spark plugs ($450), air filter ($200), and transmission fluid and filter ($850) every four years. So, be ready for those ‘extras’.

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.
