Mercedes-Benz GLC-Class vs Porsche Macan

What's the difference?

Like I said right from the start, this new, hybrid version of the AMG GLC63 is technically superior to the model it replaces in every meaningful way. It is faster, more powerful and more fuel efficient and therefore a better performance SUV than the model it replaces.

Is it a better model than the one it replaces? Ultimately that will come down to how much stock you put into the soundtrack and your feelings on an AMG not powered by a V8 engine.

Because if you can see past that, then the AMG GLC63 is an absolutely fantastic performance SUV. Not only does the new powertrain make it faster in a straight line, but the chassis is very well-balanced, making for an engaging driving experience.

For those who can look past the smaller engine they will be rewarded with an incredibly fast and rewarding-to-drive member of the AMG family.

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 GLC63 is unmistakably an AMG from the moment you first lay eyes on it. That’s thanks to the AMG-specific elements, starting with the grille with vertical strikes and the AMG crest on the bonnet; which is now a signature item for the performance sub-brand.

The GLC63 is also fitted with the Night Package II design kit; this adds a darkened grille and black chrome badging to further enhance its visual appeal.

The AMG-specific alloy wheels and more aggressive stance do mean the GLC63 stands out from the rest of the GLC range, helping it look fast even when it’s standing still.

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.

Inside the GLC63 is clearly a derivative of the rest of the range, with its C-Class-inspired design and layout, but there’s enough AMG-specific elements to ensure it looks and feels special. This starts with the AMG steering wheel, which comes not only with a thick rim wrapped in Alcantara, but also some AMG special dials to adjust the various performance settings for the powertrain, suspension and transmission.

Then there are the AMG-specific seats, which look good and offer good support for the driver and front seat passenger. The rear seats offer decent space for what is a mid-size SUV, with room enough for two adults or teenagers or three smaller kids.

Those in the back aren’t particularly well looked after though, with only rear air-con vents and small door pockets but no USB charging ports or other small item storage.

The boot is 590 litres, down from 620L in the rest of the range, thanks to the addition of the rear-mounted electric motor. There’s also no room for the temporary spare the rest of the GLC range gets and instead you have to make do with a puncture repair kit.

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.

The Macan arrives with four trim levels, the entry-level Macan, the Macan 4, Macan 4S and then the flagship Macan Turbo. The latter is just a name Porsche now applies to its go-fast models — obviously there isn’t an actual turbo in action.

The new electric range opens with the Macan, which lists at $128,400, before on-road costs. A reminder here that the old entry-level Macan with an ICE powertrain would have set you back less than six figures, so this one represents quite the jump.

Now, it should be pointed out that you can still buy the previous-generation ICE Macan, at least until supply runs dry. The brand isn’t getting any more, but suggests there are enough in the country to satisfy demand until around Q2 next year.

Next is the 4, which is $134,400 and adds a second e-motor. Then comes the 4S, yours for $149,300, before the range tops out with the Turbo, which climbs to $184,400. All prices before on-road costs.

Those are big numbers, but at least Australian-delivered cars are some of the best-specified on the planet. 

That starts with the Macan, which gets a 12.6-inch digital instrument cluster, and a second 10.9-inch central touchscreen with Apple CarPlay and Android Auto.

It rides on 20-inch alloys, has synthetic-leather seats that are heated up front and Australian cars get things like the clever 'Porsche Active Suspension Management' (PASM) system as standard.

Next up is the Macan 4, which adds a second electric motor, but otherwise largely mirrors the base car’s spec. Next on the list is the 4S, which rides on a different 20-inch alloy, picks up LED matrix headlights, sports a better Bose stereo, a panoramic roof and four-zone climate control.

Finally, the Turbo is the big dog of the electric Macan range, packing serious power, but also arriving with its own 20-inch alloy wheel design (with 21-inch wheels a no-cost option) — an augmented reality head-up display, and things like the 'Porsche Electric Sport Sound', the 'Sport Chrono Package' and a performance-focused 'Sport+' drive mode.

This is what lies at the heart of the AMG GLC63’s success or failure. As I mentioned at the beginning, the previous generation’s 4.0-litre twin-turbo V8 has been replaced by an F1-inspired plug-in hybrid powertrain.

But don’t think that means AMG is suddenly focused on efficiency over performance. When AMG says the powertrain is inspired by the brand’s success in Formula 1 racing, what it means is the battery and electric motor provides a significant performance boost to support the internal combustion engine, not just save fuel.

To that end the combination of the turbocharged 2.0-litre four-cylinder petrol engine and the rear-mounted electric motor produces an impressive 500kW and 1020Nm. That’s a massive jump over the 375kW/700Nm made by the outgoing V8.

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.

Mercedes makes no secret that the battery is designed for performance, not saving fuel. It only has a 14km EV range but can recharge quickly on the move to provide a power boost when needed.

But despite all that, the GLC63 is actually significantly more fuel efficient than the old V8, using a claimed 7.3L/100km, which is a massive 4.9L/100km improvement over the old model. Although, on our day-long test drive we didn’t manage to come close to that claimed figure and instead saw returns around 11L/100km, albeit after a lot of spirited open-road driving.

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.

Anyone who still believes in the adage ‘there’s no replacement for displacement’ hasn’t driven a modern turbocharged and hybridised engine. The GLC63 is a demonstration of the metaphorical and literal power of modern technology, combining an extremely efficient and potent internal combustion engine with an electric motor to make enormous real-world performance.

To be blunt, the GLC63 feels like a rocketship out of corners, launching with a ferocity and relentlessness the old V8 simply can’t match. It shouldn’t come as a surprise, a mid-size SUV with 1020Nm was always going to have plenty of performance, but even so it’s a shock to the system every time you give the GLC63 full throttle. Officially AMG claims it takes just 3.5 seconds to run 0-100km/h and has an electronically limited top speed of 275km/h - mighty impressive figures for a five-seat mid-size SUV.

To help get all that torque to the road, AMG deploys torque distribution technology that allows for it to be split an even 50/50 front/rear all the way to 100 per cent to the rear tyres.

Other technologies deployed to enhance its handling include AMG Ride Control suspension with adaptive damping and rear-axle steering. There’s also eight AMG Dynamic Select driving modes and four AMG Dynamics settings (Basic, Advanced, Pro and Master), so it’s a complex vehicle that is designed for the enthusiast.

While it’s easy to drive around town, once you get out on the open road you can really get a sense of the GLC63’s performance potential. Beyond just its powertrain the suspension offers good body control and the rear-axle steering helps it feel agile and responsive. 

It’s not perfect though. At times the complexity of the system does lead to some hesitation when you put your foot down. It certainly lacks the linear power delivery of the old V8 and makes for a slightly trickier driving experience at times.

As for the sound, which is one of the biggest elements missing from the V8, Mercedes has added AMG Real Performance Sound, which features a pressure sensor in the exhaust that picks up on the engine note and plays it through the speaker system. It certainly helps make for a louder, more noticeable engine noise, but it still sounds more like an A45 than the previous GLC63 and for many would-be buyers, that’s a major turn-off.

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.

The Porsche Macan Electric is yet to be assessed by ANCAP, or by Europe’s NCAP, but it doesn’t appear to be missing any key equipment from its safety list.

That includes curtain airbags that extend all the way to the boot, AEB with pedestrian detection, lane keeping assist, a surround view camera and 'Intersection Assist'.

The GLC63 is covered by Mercedes Australia’s usual five-year/unlimited kilometres warranty.

As for maintenance, Mercedes offers service plans, spanning three to five years. Three years will cost you $5025, $6455 for four years and five years is priced from $7180. Servicing intervals are 12 months or 20,000km, whichever comes first.

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.
