Mercedes-Benz GLE-Class vs Porsche Macan

What's the difference?

There’s little wonder the GLE63 S is back for a second go around, after  clearly putting the frighteners on the Audi RS Q8 and BMW’s X5 M Competition and X6 M Competition.

After all, it’s a large SUV that sacrifices little in the way of practicality (especially the wagon) in its pursuit of high performance.

And for that reason, we’re itching to go for another drive – with or without the family.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel and meals provided.

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.

First things first, the new GLE63 S is available in two body-styles, with the wagon appealing to the traditionalists out there, while the coupe targets the style-conscious.

Either way, few large SUVs are as imposing as the GLE63 S, which is a good thing considering it wants to be taken seriously.

Up front, it’s immediately identifiable as a Mercedes-AMG model thanks to its distinctive Panamericana grille insert.

The angry look is punctuated by the angular daytime running lights integrated into the Multibeam LED headlights, while the chunky front bumper has large air intakes.

Around the side, the GLE63 S stands out with its aggressive wheelarch extensions and side skirts, with the wagon getting 21-inch alloy wheels as standard, while the coupe gets 22-inch items.

From the A-pillars onwards, the differences between the wagon and coupe body-styles start to become apparent, with the latter’s roofline much more steeply raked.

At the rear, the wagon and coupe differentiate themselves even more clearly with their unique tailgates, LED tail-lights and diffusers. That said, they do have a sports exhaust system with squared-off quad tailpipes in common.

It’s worth mentioning that the difference in body-style also means a difference in dimensions, with the coupe 7mm longer (4961mm) than the wagon, despite having a 60mm-shorter wheelbase (2935mm). It’s also 1mm narrower (2014mm) and 66mm shorter (1716mm).

Inside, the GLE63 S separates itself with its flat-bottom steering wheel with Dinamica microfibre accents, and multi-contour front seats, which are upholstered in Nappa leather alongside the armrests, dashboard and door shoulders and inserts.

The door bins are of the hard plastic variety. That’s underwhelming in a vehicle that costs this much, as you would hope cow hide – or at least a soft-touch material – would be applied to them.

The black headliner acts as another reminder of its performance focus, and while it makes for a darker cabin, metallic accents feature throughout, while the trim (our test vehicle had open-pore wood) adds some variety alongside the ambient lighting.

That said, the GLE63 S is still filled to the brim with cutting-edge technology, including two 12.3-inch displays, with one the central touchscreen and the other a digital instrument cluster.

Both use Mercedes’ MBUX multimedia system and feature Apple CarPlay and Android Auto support. This set-up is still the benchmark, thanks to its speed and breadth of functionality and input methods, including always-on voice control and a touchpad.

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.

Being a large SUV, you’d expect the GLE63 S to be quite practical, and it is, but what you wouldn’t expect is the coupe to have 25L more cargo capacity than the wagon, at a generous 655L, due to its higher window line.

That said, when you stow the 40/20/40 split-fold rear bench via the second row’s release latches, the wagon has a significant 220L advantage over the coupe, at a cavernous 2010L, thanks to its boxier design.

Either way, there’s a small load lip to contend with, making loading bulkier items a little more difficult, although that task can be made easier with the flick of a switch, as the air springs are able to lower the load height by a handy 50mm.

Better yet, four tie-down points are on hand to help secure loose items,  alongside a couple of bag hooks, while a space-saver spare resides under the flat floor.

In the second row, things are even better, with the wagon offering a crazy amount of legroom behind our 184cm driving position, as well as two inches of headroom for me.

With its 60mm-shorter wheelbase, the coupe naturally sacrifices some legroom, but it still provides three inches of legroom, while its sloping roofline trims headroom to an inch.

No matter the body-style, the five-seat GLE63 S is wide enough to seat three adults abreast with few complaints, with the transmission tunnel on the smaller side, meaning there’s plenty of room for feet.

There’s also plenty of room for child seats, with two ISOFIX and three top-tether anchorage points on hand for fitting them.

Amenities-wise, rear occupants are treated to map pockets on the front-seat backrests, as well as a fold-down armrest with two cupholders, while the door bins can accommodate a couple of regular bottles each.

A  fold-out cubby is positioned below the air vents at the rear of the centre console, containing two slots for smartphones as well as a pair of USB-C ports.

In the first row, occupants have access to the centre console’s cubby, which features two temperature-controlled cupholders, in front of which are a wireless smartphone charger, two USB-C ports and a 12V power outlet.

The central storage bin is pleasingly large and contains another USB-C port, while the glovebox is also on the larger side, and you get an overhead sunglasses holder too. Stunningly, the front door bins can take three regular bottles apiece. Not bad.

While the wagon has a large, square rear window, the coupe’s is a letterbox in comparison, so rearward visibility isn’t one of its strong suits.

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.

With cost-of-entry sitting at $92,700, before on-road costs, the Macan T is positioned just above the entry-level grade in a four model line-up.

And it stacks up against well-credentialed and well-equipped competitors like the Audi Q5 45 TFSI S line Sportback ($90,600), BMW X3 xDrive30i M Sport ($91,900), and Mercedes-Benz GLC 300 ($92,300).

Aside from the performance and safety tech covered later, the standard equipment list includes the often optional ‘Sport Chrono Package’ (including a mode switch and ‘Sport Response’ button on the steering wheel), as well as a 10.9-inch HD multimedia touchscreen, sat nav (with voice control), three-zone climate control, eight-way electrically-adjustable sports front seats (with driver’s side memory), heated front seats, cruise control, as well as keyless entry and start.

Also included is combination leather and ‘Sport Tex’ cloth seat trim (with silver contrast stitching), a leather-trimmed heated GT sports steering wheel, 10-speaker/150-watt audio with digital radio as well as Bluetooth and Apple CarPlay connectivity (no Android Auto, though), a 4.8-inch configurable info display in the instrument cluster, 20-inch alloy rims (finished in ‘Dark Titanium’), LED headlights, tail-lights and daytime running lights, plus an auto tailgate. There’s more, but you get the idea.

Worth noting our test car featured more than $25K’s worth of options. Specifically, a leather trim package ($3280), panoramic roof ($3110), sports exhaust ($3080), adaptive air suspension ($2790), 18-way adaptive sports front seats ($2410), Bose 14-speaker/665-watt audio ($2230), ‘Papaya Metallic’ paint ($1800), tinted LED headlights with ‘Porsche Dynamic Light System Plus’ ($1650), adaptive cruise control ($1620), carbon interior trim package ($1600), lane keeping assist ($1100), high-gloss black roof rails ($650), and Porsche logo door courtesy lights. Total price as tested (before on-road costs) $118,560.  

At that money you’re more in line with the Audi SQ 5 Wagon ($110,400), BMW X3 M40i ($118,900), and Merc-AMG GLC 43 ($129,000). A tough trio to get your nose in front of, but the Macan T still presents pretty well.

The GLE63 S is powered by Mercedes-AMG’s ubiquitous 4.0-litre twin-turbo V8 petrol engine, with this version pumping out a hard-hitting 450kW of power at 5750rpm and 850Nm of torque from 2250-5000rpm.

But that’s not all, because the GLE63 S also has a 48V mild-hybrid system called EQ Boost.

As its name suggests, it has an integrated starter-generator (ISG) that can provide up to 16kW and 250Nm of electric boost in short bursts, which means it can also reduce the sensation of turbo lag.

Mated to a nine-speed torque-converter automatic transmission with paddle-shifters, and Mercedes-AMG’s fully variable 4Matic+ all-wheel-drive system, the GLE63 S sprints from a standstill to 100km/h in just 3.8 seconds, in either body-style.

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 GLE63 S’s fuel consumption on the combined-cycle test (ADR 81/02) varies, with the wagon achieving 12.4L/100km, while the coupe needs 0.2L more. Carbon dioxide (CO2) emissions are 282g/km and 286g/km respectively.

When you consider the high level of performance on offer, all of these claims are fairly reasonable. And they’re made possible by the engine’s cylinder-deactivation technology and the 48V EQ Boost mild-hybrid system, which has coasting and extended idle-stop functionality.

That said, in our real-world testing with the wagon, we averaged 12.7L/100km over 149km. While that’s a surprisingly good result, its launch drive route mainly consisted of high-speed roads, so expect a much higher number in metropolitan areas.

And in the coupe, we averaged a higher but still respectable 14.4L/100km over 68km, although its launch  route purely involved high-speed country roads, and you know what that means.

For reference, the wagon has an 80L fuel tank, while the coupe has an 85L unit. Either way, the GLE63 S only takes more expensive 98RON premium petrol.

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.

Make no mistake, the GLE63 S is a big beast, but it certainly doesn’t act its size.

Firstly, the GLE63 S’s engine is an absolute monster, helping it to hunker down off the line and then charge on towards the horizon with serious vigour.

While there’s so much initial torque to begin with, you still get the added benefit of the ISG, which helps to eliminate lag as the new twin-scroll turbos spool up.

That said, acceleration isn’t always brutal, as the electronic stability control (ESC) is often quick to cut power when under full throttle in  first gear. Thankfully, engaging the ESC system’s Sport mode solves this issue.

This behaviour is somewhat ironic as the 4Matic+ system is seemingly never short of grip, with it's working hard to find the axle with the most traction, while torque vectoring and a rear limited-slip differential proportion torque from wheel to wheel.

Regardless, the transmission provides predictably smooth and predominantly timely gear changes, although they’re definitely not dual-clutch quick.

What’s more memorable, though, is the sports exhaust system, which keeps your neighbours relatively sane in the Comfort and Sport drive modes, but will drive them mad in Sport+, with hilarious crackles and pops heard loud and clear on the overrun.

It’s worth noting that while the sports exhaust system can be manually engaged in the Comfort and Sport drive modes via a switch on the centre console, it only makes the V8 rumble grow stronger, with the full effect only unlocked in Sport+.

Of course, there’s more to the GLE63 S experience, like the fact that  it somehow rides like a large SUV yet handles like a sports car.

The suspension’s air springs and adaptive dampers offer up a luxurious ride in the Comfort drive mode, with the GLE63 S wafting along with confidence. Not even its large-diameter alloy wheels pose too much of a threat to this quality on poorer country roads.

The ride is still more than liveable in the Sport drive mode, although the adaptive dampers become a  too firm in Sport+, with the ride becoming a little too jittery to be bearable.

Of course, the whole point of the adaptive dampers becoming progressively firmer is to help the GLE63 S handle even better, but the real revelations here are the active anti-roll bars and engine mounts, which effectively limit body roll to such a level that it’s almost imperceptible.

In fact, overall body control is impressive, with the GLE63 S not feeling like the 2.5-tonne-plus behemoth it is. It really has no right to attack corners the way it does, with the coupe feeling a touch tighter than the wagon, thanks to its 60mm-shorter wheelbase.

Further confidence is afforded by the sports brakes, which include 400mm discs with six-piston calipers up front. Yep, they wash away speed with ease, which is exactly what you’d hope for.

Also key to the handling is the electric power steering, which is speed-sensitive and has a variable ratio. It’s really quick in the wagon, and even more so in the coupe, thanks to its more direct tune.

Either way, this set-up is well-weighted in the Comfort drive mode, with plenty of feel and just the right amount of heft. That said, Sport and Sport+ make it gradually heavier, but neither make the driving experience better, so stick with the default setting.

Meanwhile, Noise, Vibration and Harshness (NVH) levels are pretty good, although tyre roar is consistent at highway speeds, while wind whistle is prominent over the side mirrors when travelling above 110km/h.

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.

The Macan has been around for 10 years, and despite regular updates it’s starting to give ground to competitors in terms of standard active and passive safety tech. 

With a base price within shouting distance of six figures, you’d expect the Macan T to be at the pointy end of the safety game, but not so.

While crash avoidance features include ‘Lane Change Assist’, ‘Lane Departure Warning’, tyre pressure monitoring, and ‘Park Assist’ (including a reversing camera and 360-degree surround view), other big ticket items are optional extras.

Arguably the biggest is adaptive cruise control (including AEB) at $1620, and ‘Lane-keeping Assist’ for another $1100. Blind-spot monitoring, rear cross-traffic alert and other increasingly common systems aren’t available at any price.

What? It’s as much the principle as the dollars. These things should be standard in a close to $100K Porsche.

If a crash is unavoidable there are eight airbags on-board (driver and front passenger front, front side, rear side, and full-length curtains), but the front centre airbag, increasingly included to avoid head clash injuries in a side impact, is MIA. 

Multi-collision brake minimises the chance of subsequent impacts after an initial crash, and there are three top-tether points for baby capsules/child seats across the rear row, with ISOFIX anchors on the outer positions.

For the record, Porsche doesn’t submit its cars for ANCAP (or Euro NCAP) evaluation, and so far the independent body hasn’t raided the piggy bank to purchase one for assessment.

As with all Mercedes-AMG models, the GLE63 S comes with a five-year/unlimited-kilometre warranty, which currently sets the standard for the premium market. It also comes with five years of roadside assistance.

Better yet, the GLE63 S’s service intervals are relatively long, at every year or 20,000km – whichever comes first.

It’s also available with a five-year/100,000km capped-price-servicing plan, but it costs $4450 in total, or an average of $890 per visit. Yep, the GLE63 S isn’t exactly cheap to maintain, but you expected that.

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’.
