Porsche Cayenne vs Mercedes-Benz Eqe300

What's the difference?

Of all the super SUVs I've piloted, the Porsche Cayenne Turbo GT is the best all-rounder in terms of performance, comfort, cabin technology and style.

As a family car it's roomy, practical and easy to use and drive daily.

As a performance car the Turbo GT is stupidly quick, with the agility of a sports car. Sure, a 911 would leave it behind on a twisty race track, but this SUV is close to having that sportscar experience and keeping your family, as well.

The Mercedes-AMG EQE53 SUV has some serious tech inside and will fit the family in style. If you're after the AMG experience, you may be a little disappointed as this model leans heavily towards plush rather than sports-SUV. And it does plush extremely well but it begs the question whether the AMG factor is worth the extra cash.

This might be a personal thing but to me nearly all Porsches look better from the back than the front.

It's the wide stance and powerful haunches, the hunkered down suction-capped-to-the-road look that does it for me and the Cayenne Turbo GT, despite being an SUV, passes this important Porsche checklist item.

The GT aero kit only serves to make this SUV look more of a beast, and the gold-bronze looking satin Neodyne wheels are a Porsche theme that I've not always been a fan of, but I get the historic connection.

If only the Turbo GT could look a little less like other Cayennes from the front. This is the king of the SUV range and despite the apron and bumper already being exclusive to this model, there should be more.

Vents in the wheel arches, carbon bonnet with nostrils GT3-style perhaps? Or is that going too far? If you do want something more lairy then there's always the Urus.

The Cayenne Turbo GT's cabin is stunning in its plushness and modern surprises such as the passenger display, the hoodless instrument digital cluster, the lashings of Race-Tex upholstery everywhere. It's perfectly Porsche. High-performance meets high-end.

It's also highly practical. Let's talk about that.

We affectionately nicknamed our test EQE53 model the Blue Tic Tac because of its… well, similarity to the mint.

While not uncommon in the EV market, the EQEs pillowy design doesn't exactly scream 'big personality'. However, it does feature some cool features like the massive 22-inch alloy wheels, red brake calipers and the AMG badging at the rear. But that's all that separates it from its non-AMG siblings.

Head inside and it features all of the plush comforts and styling you’d expect from a Merc with some of the best ambient lighting in the business and a sunroof that manages to make the cabin feel airy despite all the black trims. 

Some of those trims, like the synthetic grey panels scattered liberally throughout the cabin, are found in all EQE models and don't reflect the grade level. A trim with better tactility and style would be a point of difference.

The dashboard features three screens in a ginormous panel, which surprisingly doesn’t catch the light but does show fingerprints and every spec of dust on it. Which might annoy you as it's 100 per cent the drawcard for the interior and when it's dirty, it's very obvious.

Although I'm not in love with some design choices, it's still a lovely cabin to spend time in.

The Porsche Cayenne Turbo GT only makes one compromise on practicality and that's the removal of the middle seat in the back, which, with just two kids isn't used all the time but on average we might need it once a week for school mates and cousins.

Instead of a middle seat there is a shallow tray, which will fit a phone or in our case leaves and rocks found at the park.

So, yes, the Turbo GT is a four-seater only, but this is a spacious, large SUV with good head and legroom, wide-opening doors for easy entry and exit, and air suspension which can raise and lower the height for easy access.

Storage is excellent with enormous door pockets in the front and back and there are four cupholders.

There's a wireless phone charger in the front and two USB-C ports as well, plus two USB-C sockets in the back.

Four-zone climate control means the kids in the back can set their own temperatures. They also have heated seats.

I was disappointed to see there aren't sunshades for the rear windows - pretty vital in Australia where it feels like we're only about 50 metres away from the sun.

The Turbo GT's 576-litre boot just managed to fit our pram and a week's shopping, which is our minimum standard for living. Any more space is a bonus.

The cabin of the EQE53 offers plenty of head- and legroom for its occupants. Using the armrests is also a civilised affair as there's not fighting for elbow positions!

Access to both rows is (annoyingly) more complicated than it needs to be because of the sidesteps - which are, quite frankly, useless on a car like the EQE. They hit your shins/calves when you're not using them and using them feels silly.

All seats offer a tremendous amount of comfort but the fronts benefit from heat and ventilation functions that keep you relaxed year-round. They extend everywhere you need them to to get into the best seating position.

Storage is excellent throughout the car and in the front there's an extra-deep middle console (it swallows most of my arm), a large centre console that features retractable cupholders and a big shelf underneath for bulky items, like a handbag, or as my mum joked, Saturday night’s takeout and a bottle of wine!

Each door pocket gets a dedicated bottle holder and the rear also gets two retractable cupholders and a pair of map pockets.

The boot has 520L of capacity available which is a good size for the class and the wide boot aperture and level loading space make it easy to slide things in and out. You miss out on underfloor storage in the EQE53 model but the back seat has a 40/20/40 split to open up storage options.

The technology looks daunting but is very user-friendly once you spend some time with it. The main multimedia system is responsive and you can access the menus from the steering wheel controls as well as the touchscreen.

The system has wireless Apple CarPlay and Android Auto and satellite navigation, all of which are easy to use. Charging is good with eight USB-C ports (six up front!) and a wireless charging pad.

Despite having four co-pilots this week, the additional screen in front of the passenger remained mostly unused and ended up being more of a novelty.

The real bugbear has been the air-conditioning system. Despite having a pre-climate function, it takes ages for the car to cool down and my eight-year old struggled in the rear the most. The rear vents just don't seem to pump much out, even on the top speed setting.

Once the system has cooled the cabin, though, it's like a fridge. But until it does... you really notice the 30+ degree days!

The EQE SUV is available in three grade levels and the EQE53 model on test for this review here is the creme de la creme, tucking in under AMG badging, and all that implies. Sitting at $191,900, before option packs or on-road costs, positions the top model in between its high-performing electric rivals, the Audi SQ8 e-tron at $173,090 MSRP and the BMW iX M60 at $228,400 MSRP.

Our test model has the optional 'AMG Dynamic Plus Package', which adds $5691.40 to the price tag but includes a bunch of features AMG-lovers will appreciate. Items like an 'AMG Sound Experience' which gives you three motor soundscapes to choose from, a track pace function, improved motor outputs and a boosted top speed of up to 240km/h.

In terms of technology, the not-so-standard fare includes a seriously cool-looking multimedia display consisting of a 3D Burmester surround sound system and three digital screens covering the width of the dash.

The tech is rounded out by wireless Apple CarPlay and Android Auto, satellite navigation, four-zone climate control, eight USB-C ports, a wireless charging pad and digital radio.

The top model also gets some luxuries like heated and ventilated front seats featuring a three-position memory function, electrically extendable under-thigh support and a 'kinetic' function (think light stretching rather than massage).

The upholstery and trims are a good mix of black Nappa leather on the seats and doors (partial), as well as synthetic suede-like materials on accent panels throughout the car.

Practical items include a hands-free powered tailgate, rain-sensing wipers, keyless entry/start, pre-entry climate, dusk-sensing headlights and a park assist function to help in tricky car spots.

Overall, the EQE53 is fairly well packaged but does miss out on a few luxury extras in the second row, which is noticeable because its rivals cover this area a little better.

As a middle-aged parent with two children, a Porsche that I don't have to crawl into and out of like a cubby house is a great thing.

What's even better is that this ‘easy access' Porsche is every bit as brutally powerful and fast as the quintessentially ‘pure' Porsche, the 911. Actually, it's more powerful and faster.

The Turbo GT's twin-turbo 4.0-litre V8 petrol engine makes 485kW and 850Nm with drive going through an eight-speed transmission to all four wheels.

In comparison, a Porsche 911 GT3 RS, arguably the most brutal and anti-social 911, has 386kW/485Nm.

I haven't made a mistake. Those are the real numbers. And it's only when you step on the accelerator in the Cayenne Turbo GT, and it feels like somebody's sat down on your chest, that you realise what a big deal this is.

That is such a colossal amount of oomph that this 2.2-tonne family SUV can accelerate from 0-100km/h in 3.3 seconds.

The 911 GT3 RS can do it in 3.2 and it has a roll cage and a fixed rear wing the size of a bedroom door.

And yes, we're now coming into a digital age where Teslas and other electric SUVs are quick, too, but can they go around corners like a Porsche Cayenne Turbo GT?

Do they have the same rumble and roar as a twin-turbo V8 that's terrifying and enticing at the same time.

The correct answer is, absolutely not.

The EQE53 is an AWD and has dual electric motors - one at the front and one at the rear.

Without the optioned AMG Dynamic Plus Package, the motors produce up to 460kW and 950Nm but with the package those outputs jump up to a staggering 505kW and 1000Nm!

That means the 3.7-second 0-100km/h sprint time also improves to 3.5-seconds. Suffice it to say, it's enough to blow your hair back and considering we have no roads in Australia you can really let this thing loose on, it's more than enough power for anyone.

Seriously? This is a 2.0-tonne twin-turbo petrol V8 with a 90-litre fuel tank. Even the Porsche specs sheet doesn't understand the question because in the column for fuel efficiency there are three letters - tbc.

My own testing saw me record 22.5 L/100km at the fuel pump, which means I enjoyed driving the car very much.

A little digging around reveals Porsche globally claims the Turbo GT will use 12.6L/100km, over a combination of open and urban roads.

You might not have as much fun as I did but easing back a little might get you closer to the 700km of range this more frugal consumption figure appears to offer.

While efficient it isn't, I'm not going to mark the Turbo GT too much here because compared to its petrol rivals the fuel consumption is what I'd expect from such a high-output heavy SUV.

Non-AMG EQE models see decent driving ranges over the 500km mark, but the EQE53 has an official range of up to 485km which again positions it in the middle of its rivals. So, not bad, but a larger range would be welcome as the EQE53 is a comfortable road-tripper!

The EQE53 has a a claimed consumption figure range of 23.0 to 25.6kWh and a lithium-ion battery with a large 90.56kWh capacity.

After a week of open-roading, city-driving and not being shy in using its power, my average has been around 25.5kWh, which is solid for an electric performance SUV.

The EQE53 has a Type 2 CCS charging port which means you can hook it up to the faster DC chargers and it accepts up to 170kW on this type of system meaning it goes from 10-80 per cent in as little as 32 minutes. On an 11kW AC system, expect it to hit 100 per cent after 14.5 hours. 

Never have I met a car this powerful and superbly athletic that is as pleasurable to drive alone on great, fast roads as it is to pilot at 50km/h in the suburbs with a family on board.

It exceeds my understanding of engineering that something this large can move so quickly. That in an instant can turn and tip into a corner with such precision and effortlessness.

Yet it can switch seamlessly and happily to coping with speed bumps and potholes, delivering a ride so comfortable it'll send babies off to sleep. And it did.

The only issue, and this is such a tiny thing, is the dash-mounted gearshift, which means having to reach up and select Drive or Reverse or Park, which, when executing a three-point turn, is necessarily frustrating.

Still, I'm giving the Turbo GT a 10 out of 10 for driving under all conditions, and we didn't even go off-road, which of course you can do, as long as it's not too wild.

I really wanted the AMG EQE to be crazy-fun like its petrol-powered cousins but while it has the specs to support that wish, it never feels wild.

That's not necessarily a bad thing, just unexpected for an AMG model. The 53 is still one cool customer and its composure on the road is wonderful but it's a model that a grandparent could get into and not feel overwhelmed by. Power is smoothly delivered and when you need to take off, it responds eagerly .

Steering is firm and responsive but it’s the rear axle steering that makes the EQE53 feel nimble in the city or a tight car park despite its bulky size. It corners well, without much roll and you can tackle a winding road at speed with confidence.

The ride comfort is very good with minimal outside noises finding their way inside and the suspension is plush without feeling like you’re floating on top of the road.

The visibility is mostly good but the wide A-pillar is annoyingly in the way for my driving position and I have to duck my head around it to see clearly on roundabouts.

The 360-camera system is top notch but the camera angle turns when you move the steering wheel, which takes some time to get used to. Otherwise, the EQE53 is an easy one to park.

The EQE53 hasn’t been assessed by ANCAP yet but its siblings achieved a maximum five-star safety rating in 2023.

The top model enjoys a long list of safety features, including 10 airbags which is outstanding for a family SUV.

Other systems include blind-spot monitoring, an SOS call button, driver monitoring, safe exit warning, rear occupant alert, rear collision warning, forward collision warning, rear cross-traffic alert, lane departure alert, lane keeping aid, traffic sign recognition, an intelligent seatbelt warning, adaptive cruise control (with stop/go), park assist, a 360-degree view camera system as well as front and rear parking sensors.

There are two ISOFIX child seat mounts and three top tether anchor points across the second row but two seats will fit best.

None of the safety systems intrude on daily driving either, which is great.

The Cayenne Turbo GT is covered by Porsche's three-year, unlimited kilometre warranty, which is lagging behind in terms of duration even compared to other luxury brands such as Mercedes-Benz, which offers five years.

Servicing is recommended annually or every 15,000km, although there isn't a capped price maintenance plan with final costs determined at the dealer level (in line with variable labour rates by state or territory).

The EQE SUV is offered with a five-year/unlimited km warranty, which is not unusual for its grade level but it has a longer-than-usual battery warranty of up to 10-years or 250,000km.

You can pre-purchase a three-, four- or five-year servicing program. The three-year program costs a flat $2240, while the four-year program costs $3525 and the five-year option costs $4085.

All pricing is pretty competitive for the class but servicing intervals are odd at every 12-months or 25,000km as it's typical to see intervals on EVs at 24 months.
