Porsche Cayenne vs Mercedes-Benz Eqe53

What's the difference?

There is a lot riding on this new Cayenne Electric, it is the sales leader for the German brand and if it suffers the same sales decline as the Macan, that will be a big concern for Porsche.

The good news is it’s an impressive all-rounder, with an incredible breadth of capability. But so is the electric Macan.

Going electric hasn’t diminished its trademark Porsche elements, and instead has amplified them in many respects. The speed is nothing short of staggering in the Turbo, but across the range the on and off-road driving ability is impressive. 

Plus it has the kind of spacious, well-considered and premium appointed cabin you should expect for a luxury SUV.

There are two key differences that could see it succeed where the Macan has faltered. Unlike the Macan, Porsche’s decision to give Cayenne buyers the option to stick with internal combustion if they prefer, is likely to ensure it remains a popular member of its line-up for years to come.

And while the Macan was perhaps too much, too soon, the Cayenne arrives at a time when Australians are embracing electric cars more than ever before. Although the luxury and performance end of the EV market is growing more slowly than the mainstream.

As for the pick of the range, as mind-blowing as the Turbo is, the truth is (like pretty much every Porsche model) the entry-level Cayenne is arguably the pick of the bunch. It has all the performance you’ll reasonably need and offers a good blend of capability and luxury for the lowest price.

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

In the wild new world of fully electric cars there isn’t really an ‘average’ of what to expect. If there was, I’m sure the EQE 53 would exceed it. Its electrification brings the ambiance of a luxury car, while its performance reminds you of what AMG is capable of.

There’s a bit of the mechanical engagement of AMG missing, a relatively small boot, and some won’t be sold on the function-over-form looks, but the EQE 53 is a pleasantly surprising look at the future of fast Mercedes.

For all the positives of continuing to offer the previous generation Cayenne alongside the new one, it does come with some downsides too. The most obvious is unmissable design differences between the older generation and this newer one.

This new electric version has the same basic silhouette of the previous Cayenne, but the details give it a distinctive look. Being electric it needs to cut through the air as efficiently as possible, so this new model is longer and lower than the internal combustion versions.

The details of the design also give it a sharper, more modern look too. Not that the previous Cayenne suddenly looks old and outdated, but if you stick with petrol power you will be sacrificing the latest styling.

Another surprising design element with this new model is an optional off-road package, which includes a unique front bumper for greater off-road clearance and approach angle. It’s unlikely that too many Cayenne Electric owners will head deep into the bush, but for those who want to, the unique bumper will help them go further. 

However, it does create a rather unusual look, as it has quite a pronounced undercut, or what I referred to as an ‘overbite’ that definitely doesn’t look as well-proportioned as the standard bodykit.

Inside, for all the hype around Porsche performance, one of the brand’s standout features has always been interior design. 

This new Cayenne looks really interesting inside, with curved screens for the digital instrument display and the multimedia system, as well as the option to add a third screen in-front of the passenger. 

The overall level of fit and finish, the detail and quality of the materials is exactly what you’d expect from a premium brand and an SUV at this price point.

The EQE is certainly a departure from the classic lines of the current E-Class sedan. Mercedes-Benz has chosen to take a completely new approach for the electric era, embracing the need for ultra-low drag designs, and a corresponding newfound love for curvaceous surfaces.

It’s fairly imposing too with enormous wheels and an abundance of panels. Needless to say some will find this new design direction challenging. It proved quite controversial in the CarsGuide office, at any rate.

I can say it looks a bit more approachable when witnessed in the metal, and the AMG branded 53s I sampled for this review added a few more much-needed points of interest to this single curve of a design.

This is particularly notable around the rear of the EQE 53 which adds a little tail spoiler and glossy rear diffuser, which help accentuate the width and terraced design of the rear window.

Around the front is a little more featureless, with the blanked-out grille losing the intricate three-dimensional appeal of this car’s combustion equivalents. There’s just something a bit plain about the EQE’s face, although Mercedes has tried to spice it up with interesting headlight clusters.

The inside is spectacular, with a smorgasbord of screens and lights to match an abundance of glossy touch-based surfaces. Some may not be sold on the over-the-top approach, but it feels as futuristic as an EV should be.

The material choices are nice, too, with soft-touch materials atop the dash, doors, and running down the centre console. The ambient lighting is particularly flashy, and works in with the consistent single-piece sort of design which makes up the whole dash.

While the LEDs might be a little too much for some, there are some more subtle detailing points, like the way the centre air vents are delicately worked into the flow of the dash, and the rotor designs of each vent at the edges are intricate pieces.

As for the space and practicality, once again Porsche showcases that it’s not a one-trick pony brand. As fast as the Cayenne Electric is - and is very fast - the designers have also ensured it is a genuinely spacious vehicle for a family.

The second row space is good, enough to take two adults in comfort and easily accommodate three kids.

The SUV is obviously the more practical of the pair, with the Coupe losing some rear headroom.

As for the boot, space varies between 781L for the Cayenne SUV and 747L for the S and Turbo SUVs, while the Coupe looks sleeker but comes at the expense of cargo capacity, dropping to 534L for the Coupe and Coupe S and just 500L for the Coupe Turbo. 

The technology integration is well-considered too. One highlight is the new curved central multimedia screen, which has a palm rest that extends out from the centre fascia to make it more ergonomic to use the screen. 

The intuitive menu, as well as the physical controls for the volume and climate control, plus the ability to integrate the smartphone apps, means the key non-driving functions are incredibly easy-to-use, even on the move. 

Integrated into that palm rest is a large centre console space between the front seats, which has both wireless smartphone charging as well as four USB-C ports and two cupholders. It means there is plenty of small item storage space to go with all the room for people.

The EQE is plenty practical up front, with an odd SUV-like seating position providing a commanding view of the road. This seat positioning isn’t an accident or a necessity of facilitating batteries under the floor, but a deliberate design decision by the brand to try to emulate some design choices which have made SUVs so popular.

The result is surprisingly effective, but doesn’t help the view out of the rear of the car, which is a restricted letterbox aspect courtesy of a slinky roofline and tall boot lid.

Still, peering down on the road lets you position and park this large EV more easily. Adjustability isn’t bad for the front passenger, and space is healthy both in terms of width and height. One dimension which can’t be altered is the particularly tall dash height, and while this is largely overcome by the taller-than-average seat, it could be an issue for shorter drivers.

Storage is great, with a big bottle holder and bin in the doors, a huge cutaway below the floating centre console for storage, with an elastic strap for tying down objects. There are a further two bottle holders in the centre console and a bay with a wireless charger, too, and the split-opening armrest box is deep.

One of the more divisive points of this car’s practicality offering is the screen-based functions. Everything has been moved into the massive centre screen. There are no tactile buttons or dials for this car’s functions, with it all controlled through context menus.

To be fair, with the amount of real estate on offer, the touch elements can afford to be massive, and there is a permanent set of climate controls at the base of the screen, but adjusting these functions on the fly is never as easy without physical feedback.

The same goes for the touch-centric wheel controls. Benz says the idea with the four-zoned touch panels on the wheel is to offer unrivalled ability to control the car’s functions even when the wheel is at an angle, but it is also easy to accidentally hit various touch functions, and they can require some delicate action to use properly.

The back seat is impressive. It maintains the tall seating position of the front, letting you look down on the road as though you’re in an SUV, and the comfortable seating and surfaces continue. Legroom is particularly impressive, with leagues of space behind my own driving position. Headroom is even okay considering the descending roofline. It’s quite dark in the EQE 53 we tested thanks to its black-on-black trim, giving the illusion of a space which is smaller than it actually is.

Storage is good, too, with a big bottle holder in the door cards, quad-zone climate control, complete with a separate touch panel for rear passengers, adjustable air vents, and solid clamshell pockets on the backs of the front seats.

The EQE has a boot capacity of 430 litres which doesn’t seem enormous given the footprint of this car, and no doubt has a lot to do with its slinky aerodynamic design around the rear. There’s no ‘frunk’ either so this is a car perhaps more focused on driving and being driven in than its ability to carry things.

We don’t yet know which EQE variants will be offered in Australia. The car we drove for this review, the EQE 53 AMG is the top of the range, and will be the launch variant in Australia, but the brand is yet to settle on how it will fill the line-up underneath.

Representatives said to expect at least two more Mercedes-Benz (as opposed to AMG) branded variants, with the option of a rear-wheel drive entry model and an all-wheel drive mid-grade. Whether they adopt the same spec level as the European-market EQE 350 remains to be seen.

As for the EQE 53, CarsGuide understands a price north of $200,000 is likely when it arrives before the end of 2022.

Its rivals will include other high-end four-door models like the Porsche Taycan, Audi e-tron GT, and the updated Tesla Model S. In the coming years this segment will continue to heat up with the yet-to-launch Hyundai Ioniq 6 and Polestar 5.

The EQE is fairly large, offering dimensions comparable to that of the CLS which came before it, and is quite unconventional in a host of areas.

The standard suite of equipment we sampled is impressive, too, with performance enhancements on the 53 including four-wheel steer, adaptive dampers, a performance brake package, and torque-vectoring all-wheel drive.

Massive 21-inch alloy wheels featured on our car, and there is also the option overseas for even higher performance carbon ceramic brakes.

Outside also features LED headlights, DRLs, and tail-lights, while inside impresses with the massive dash-spanning ‘Hyperscreen’ with panels for the digital dash, centre multimedia screen, and a third panel for the front passenger.

This set-up is optional on the EQE range in Europe, but we’ll have to wait and see what becomes standard for the Australian market. The car we sampled had wireless phone mirroring tech, wireless charging pads, built-in navigation with augmented reality directions, a head-up display with configurable panels, and full USB-C connectivity throughout.

Quad-zone climate also features, as does the brand’s latest steering wheel, in our case clad in Alcantara and leather trim.

The seats, even on the EQE 53 ship standard with the ‘Artico’ synthetic leather trim, although they can also optionally be upgraded to full Nappa leather. Electrical adjustment is standard for the front seats.

It’s a flashy cabin which feels primo, and little touches like unique materials for the EQ range across the dash and ambient lighting configurable to any colour you can dream up are neat, too.

Check in closer to the EQE’s local arrival time before the end of 2022 for more accurate pricing and spec, as well as the list of option packs.

As mentioned earlier, there are three initial Cayenne Electric variants and each offer a different powertrain option. All are dual-motor, all-wheel drive but the power levels vary greatly depending on what you spend.

The standard Cayenne Electric comes with 300kW (325kW on Overboost), which is enough for this five-seat, family friendly SUV to launch 0-100km/h in just 4.8 seconds, which is genuinely impressive.

However, stepping up to the Cayenne S raises the power level to 400kW (490kW on Overboost) and drops the 0-100km/h time to 3.8 seconds.

Finally there’s the Cayenne Turbo, with up to 850kW of power and a claimed 0-100km/h capability of just 2.5 seconds. Which is borderline crazy for such a big SUV. 

It is worth explaining that the 850kW claim for the Cayenne Turbo is only available for short bursts of performance when you activate Overboost, and the ‘standard’ output for the two electric motors is 630kW, which may sound like a lot less but is actually more than enough to make the Cayenne Turbo feel fast anytime you need more performance.

The EQE 53 punches out huge power, with the standard car producing 460kW/950Nm from its dual electric motor set-up, or with the 'AMG Dynamic Plus Pack', producing even higher figures of 505kW/1000Nm.

Clearly, AMG’s electric vehicles will safely outrun their dramatic combustion predecessors. In fact, with the Plus Pack, the EQE 53 is capable of moving its bulk from 0-100km/h in just 3.2 seconds. Extreme for something carrying a whopping 90.6kWh of batteries under the floor.

Enhancements include torque-vectoring all-wheel drive, all-wheel steer, adaptive dampers, and the choice of standard performance brakes or a carbon ceramic package.

The Cayenne is Porsche’s third electric model, after the Taycan and Macan, and it shows. The brand has taken battery production in-house for the Cayenne, producing the 106kWh unit at its own factory in Eastern Europe.

Range is rated at 542km for the Cayenne, 571km for the Cayenne S and 537km for the Cayenne Turbo.

Thermal efficiency is the key selling point for Porsche, as it unlocks not only the peak performance but also the repeatability that allows the Cayenne to launch so quickly over and over again. It’s notable, that unlike most other EVs that get slower the more time you extract peak performance out of them, Porsche was happy for us to undertake multiple acceleration runs in the same vehicle.

But that’s not the only trick Porsche has up its sleeve. It will be introducing inductive charging with the Cayenne. This means you’ll be able to buy a charging pad you can place on the floor in your garage, and simply drive it, park on top of it and the Cayenne will charge wirelessly.

This has the potential to be a game-changer for EV buyers as it removes the need to plug in to replenish the batteries, making life even easier for owners. It’s not available in Australia at the time of publication, but the company says it will be available from the fourth quarter and all Australian-delivered models, even those sold now, will be able to be retrofitted to take advantage of the technology.

Electric vehicles appear to have the same issues as their combustion counterparts, in that they still drop in efficiency the more powerful you make them. In the case of the EQE 53, this means an average WLTP-rated consumption number between 20.3kWh/100km and 23.2kWh/100km.

'Thirsty' for an EV, although it is on par with the Porsche Taycan and still below Audi’s e-tron S.

When it comes to charging the EQE 53 can charge at a rate of 11kW on the AC standard, or a whopping 170kW on DC - allowing 180km of range to be added every 15 minutes. It also has the convenient option of a 22kW AC charger, a welcome inclusion if you intend to charge your car often at public outlets.

Total range for the 90.6kWh battery is 513km on the WLTP cycle.

Porsche Australia invited us to drive the new Cayenne Electric in Port Lincoln, South Australia. While a picturesque part of the country, it seemed like an unlikely venue to test drive a new Porsche, as it’s typically Ford Ranger/Toyota HiLux country.

But one of the reasons Porsche launched the Cayenne Electric in regional South Australia was because they had managed to find a small airstrip we could use to fully explore the acceleration potential. 

Even some operator error, which meant my launch was using ‘just’ the 630kW, the acceleration was sickeningly fast and had me hitting more than 170km/h in just 200m. With the full 850kW unleashed the Cayenne is actually faster 0-100km/h than Porsche’s hero sports car, the iconic 911 Turbo S. 

That alone is a remarkable achievement, but Porsche had a few more reasons for taking us to Port Lincoln. After a drive on some sealed roads, which demonstrated the SUV's on-road composure, we found ourselves heading off-road… more off-road than I thought possible (or at least sensible) in a Porsche.

After surviving some of the gnarliest rocky roads, we found ourselves in some stunning sand dunes. We were driving the Cayenne S with the optional off-road package but the only other modification was to let down the tyres.

Carving through sand dunes like you’re in the Dakar Rally is likely to be a rare job for the Cayenne Electric, but the fact it is capable is immensely impressive and helps to demonstrate the breadth of capability that this electric SUV has.

But Porsche wasn’t finished showing off just how multi-talented the Cayenne is. 

They had a Cayenne Turbo attached to a trailer, carrying the previously beaten 911 Turbo S, to prove that it can live up to its claimed 3500kg towing capacity.

Towing a nearly $600k sports car with a $260k SUV is an expensive way to demonstrate the point, but the Cayenne didn’t miss a beat. Certainly the battery was dropping more rapidly than it was unladen, but the electric Cayenne underlined that it can do everything the petrol versions can manage (at least over a short distance).

The way the EQE 53 drives was deeply unexpected. Just looking at this massive sedan, I would have expected it to feel burdened by its batteries, and with its length and shape, cumbersome in the corners. That wasn’t the case at all.

The EQE 53 feels remarkably coherent from behind the wheel. The seating position works well to give a nice view of the road, the steering feels a tad artificial but still direct with some AMG magic having worked its way in.

What surprised me most is how agile it feels. Once you gather some speed and attack some corners, this car shrinks. Control is excellent thanks to the massive tyres, all-wheel drive system, and all-wheel steering. It sounds like a lot of complexity, but you don’t notice any of it. Each system does its part to allow you to simply point the car where you want it to go at pretty much any speed. It is very impressive.

The ride feels supple, too, thanks to adaptive dampers, but offers plenty of control. The speed is Tesla-style violent. Put your foot to the floor in Sport or Sport+ mode and you’re thrown to the back of your seat as the car enters a state of warp. AMG says there won’t be a 63 version of this car, and I can’t imagine why you could possibly need anything faster or more capable than this 53 version. 1000Nm of torque!

This overwhelming number perhaps makes it more impressive that it’s hard to extract a squeak from the tyres. Sure there’s torque-vectoring magic at play, but even at full acceleration they hold on for dear life.

It also makes a noise. AMG is very specific about what went into making the soundscape for the EQE because in the electric era its performance can be achieved silently, and the brand knows full well its badge usually comes hand-in-hand with aural drama.

I stuck it in the stock mode and varied my driving from 'Comfort' to 'Sport+.' The sound builds as the car gains speed, but it also interacts with your accelerator and brake inputs, as well as being one of few EVs with a specific noise for regenerative braking. It sounds… odd.

There’s certainly a kind of drama to it, and to me, it’s better to have it as a way of gaining some feedback from the car. But, its artificial nature and loudness became a little too much for sustained driving in Sport + mode. I found the best balance in the more regular ‘Sport’ mode, or even toned down to ‘Balanced’ which puts it in the background.

This leaves quite a void, though. While the sound is welcome, and the throttle alarming, there’s just something missing from the usually brash AMG badge promise.

As an EV, the EQE 53 has three regen modes quite distinct from one another. Mercedes says the choice to have just three modes is deliberate, as it didn’t want to dilute the personality of the car with an overwhelming choice of regen. The three modes include: basically no regen, moderate regen, and the full regen, essentially a single-pedal driving mode. I preferred the strongest setting for efficiency's sake (plus it brakes for you as you let off!).

The EQE 53 is surprising in so many areas, and much more engaging to drive than its exterior visage might suggest. I’m impressed.

We don’t yet know what standard safety equipment will arrive on Australian-delivered EQE variants, but you can expect a high-end suite of gear including auto emergency braking to freeway speeds, lane and blind spot assistance, driver and road monitoring tech, as well as the brand’s rather good autonomous cruise suite.

The EQE pairs the expected set of airbags with an additional driver’s knee airbag and centre airbag for some markets, as well as a second set of side impact airbags for rear passengers. There are dual ISOFIX mounts on the rear outboard seats, and expect there to be the usual three top-tether mounts in Australia, too.

Stay tuned closer to the EQE’s arrival toward the end of 2022 for more accurate specification.

The Cayenne Electric is covered by Porsche’s usual three-year/unlimited kilometre warranty, and the battery gets eight years of coverage.

Both of these are fairly standard by historical terms, but with so many luxury brands - including Audi, BMW, Lexus and Mercedes-Benz - all now offering five years of coverage, it does leave Porsche lagging behind.

Servicing intervals are every 12 months or 15,000km, whichever comes first, which is standard for an internal combustion engine vehicle.

Porsche doesn’t offer capped-price servicing, so prices may vary from dealer to dealer. However, the brand does sell a special EV-focused ‘Porsche Scheduled Maintenance Plan’ that costs $1995 for three years, $3695 for four years and $3995 for five years of servicing. 

Mercedes-Benz in Australia currently offers a range-wide five-year and unlimited kilometre warranty, a standard which is spreading to other premium brands.

We don’t know what the service schedule or running costs will look like for the EQE range yet, but expect it to be most affordable when chosen with a multi-year prepaid service plan at the time of purchase. Check back closer to its launch time to see the full details.
