Mercedes-AMG E63 vs Zeekr X

What's the difference?

The E 63 S fills its niche in AMG's Australian line-up perfectly. More mature than the brand's four-cylinder hatches and SUVs, but not as overbearing as some of its bigger sedan, GT and SUV stablemates. And its ability to seamlessly switch between serene comfort and dynamic performance has nailed the objective for this 2021 update.

It's a good thing in a small package, this Zeekr X, and there are a lot of things I like about it. In fact, the only sticking point for me is the price. But that's all about perspective. If you see this as a newcomer Chinese brand, then yes, there are a lot of more affordable options out there. But if you see it as a premium player, it's really a more affordable version of a Volvo.

The E 63 S has been massaged for 2021 starting with flatter headlights, AMG's now signature 'Panamericana' grille, and a high gloss black flap across the top of the curved 'Jet Wing' section defining the lower part of the nose.

At the same time, the vents on either end of it are larger and feature twin transverse louvers to guide cooling air to wherever it's needed.

It's all about what AMG calls 'optimised aerobalance' but the form is just as appealing as the function. The characteristic 'Power Domes' in the bonnet dial up the muscle, as do the fat wheel arches (+27mm each side), and 20-inch rims with distinctive aero inserts.

This car's optional exterior carbon package consists of a front splitter, side sills, a flash near the fender badges, the exterior mirror covers, the boot lid lip spoiler, as well as the lower apron around the redesigned diffuser and quad tailpipes.

New, intricately styled LED tail-lights are also flatter, but there's even more going on inside.

A new AMG sports steering wheel features three rounded twin-spokes with new switches on the bottom to control the car's dynamic set-up.

It also picks up a new take on the small touch-sensitive controllers used to adjust the instrumentation and manage other functions like phone calls, audio and the cruise control.

Not sure I'm in love with them at this stage. In fact, the words fiddly, imprecise, and frustrating come to mind.

Nappa leather covering the superb AMG sports seats, upper dash, and door beltlines remains standard, but the show-stopper is the 'Widescreen Cockpit' - twin 12.25-inch digital screens for the MBUX multimedia interface on the left and instruments on the right.

The instrument cluster can be set to 'Modern Classic', 'Sport' and 'Supersport' displays, with specific AMG read-outs such as engine data, gear speed indicator, warm-up status, car set-up, as well as a G-meter and 'RaceTimer.'

To borrow an official automotive design term, it looks schmick. Overall, with touches like open-pore black ash wood trim, and brushed metal highlights, the interior looks efficient but classy, with an obvious attention to detail in the layout and its execution.

The visual changes aren’t massive. This AWD version welcomes a couple of new exterior colours, including the 'Matt Khaki Green' of our test car. It also gets the two-tone black roof and there are new 20-inch alloy designs.

Elsewhere, it's the futuristic-style of design we’re used to which differentiates the X from its Volvo EX30 twin under the skin.

Inside, this is a seriously well-equipped and polished-feeling small SUV, and — unlike some of the newcomer brands to Australia — it all feels very high quality and well put together. And that includes the material choices.

I don’t even hate the fact that most of the functions are controlled via this screen, thanks to the little shortcuts glued to the home screen. I do, however, hate the fact that there’s no easy way to change the wing mirrors or shortcuts for toning down some of the safety stuff.

That aside, though, it’s a nice and high-quality feeling space.

At just under 5.0m end-to-end the E-Class sits in the upper range of the mid-size luxury spectrum. And almost 3.0m of that is accounted for by the distance between the axles, so there's plenty of space inside.

The driver and front passenger are provided with heaps of room to breathe, and there's a surprising amount of space for those in the back as well.

Sitting behind the driver's seat set for my 183cm (6'0”) position I had more than adequate head and legroom. But access to and from the back is a struggle for full-size adults.

The rear doors open out a long way, but the limiting factor is the size of the aperture, necessitating excessive contortion of the head and limbs to fold in and out of the car.

Connectivity runs to two (power-only) USB-C sockets in the front centre storage bin, as well as another USB-C (for power and multimedia) and 12-volt power outlet in the centre console.

Speaking of the front centre storage bin, it's a decent size and has a padded split lid so it can double as an armrest. There are two cupholders in the front console, a generous glove box, as well as long door compartments with recesses for large bottles provided.

There's a pair of USB-Cs along with another 12-volt socket in the back, sitting under the climate control panel with adjustable vents in the rear of the front centre console. Nice.

The fold down centre armrest incorporates a lidded (and lined) storage box as well as two pop-out cupholders. Again, there are bins in the doors with room for smaller bottles.

The boot offers 540 litres (VDA) of volume, and is able to swallow our three-piece hard suitcase set (124L, 95L, 36L) with room to spare, or the substantial CarsGuide pram, or the largest suitcase and pram combined! There are tie-down hooks to help secure loads, too.

Don't bother looking for a spare of any description, a repair/inflator kit is your only option. And the E 63 S is a no-tow zone.

You know you're in a small vehicle when you can't fit two large (not those crazy American-style jumbo cups, just normal coffee-shop takeaway) coffees in the cupholders, but so it is with the Zeekr X.

The small SUV's 4432mm length, 1836mm in width and 1566mm height doesn't leave much room to spread out up front. There's ample room for driver and passenger, of course, but we are talking about a small vehicle here.

Clever storage helps to mitigate that, though, especially the super-deep storage space in the centre console and the very clever fridge that separates the driver and passenger seats.

Weirdly, though, the space doesn’t feel overly tight in the back seat. We had a massive baby seat in there, and that fit without issue. And full size humans can genuinely get pretty comfortable. I'm 175cm, and I had enough knee and headroom.

In the boot, there’s 404 litres of volume with the rear seats upright and 1247 litres with them folded flat. And it’s worth pointing out this isn’t intended to be a family car, but there’s certainly enough space for the shopping... and a pram.

This is a small SUV with a LOT of stuff. There are two trims in the Zeekr X range – the entry-level rear-drive model is $48,900, drive-away, while the all-wheel drive version we've tested is $57,900 on the road.

The obvious comparison is to the Volvo EX30, which shares its platform with the Zeekr X through both brands' Chinese parent company Geely.

As of right now, the cheapest single-motor Volvo is $56,051, drive-away in NSW, or $49,990 plus on-roads, making the Zeekr version much, much cheaper.

Anyway, outside there are 19- or 20-inch alloys, though our test car is fitted with the optional 20-inch black alloys, paired with a black-with-red-highlights interior treatment, which adds $2000 to the price.

Ours is also fitted with the electric front doors which open or close at the push of a button, and back doors that unlatch, but don’t fully open, the same way, which adds another $2000.

Both trims also get heated and cooled front seats, and heating in the rear window seats, but this AWD version also adds a massage function for front seat riders. 

There’s also wireless charging, a 13-speaker Yamaha sound system and — very cool, literally — is the little drinks fridge between the front seats in the AWD variant.

Tech is handled by a 14.6-inch touchscreen with Apple CarPlay and Android Auto and there’s a head-up display for the driver.

The E 63 S is powered by the M178 version of the all-alloy 4.0-litre twin-turbo V8 engine used across numerous AMG models from the C-Class up.

Thanks in no small part to direct injection and a pair of twin-scroll turbos (located in the engine's 'hot vee' to optimise throttle response), this all-alloy unit produces 450kW (that's 612hp) from 5750-6500rpm, and 850Nm from 2500-4500rpm.

And as per standard AMG practice for its Vee engines, this car's powerplant was built from scratch by a single engineer in Affalterbach. Thank you Robin Jäger.

AMG calls the nine-speed transmission used in the E 63 S an MCT, which stands for Multi-Clutch Technology. But it's not a dual-clutch, rather a normal auto transmission using a wet clutch as opposed to a conventional torque converter, to connect it to the engine on take-off.

Drive goes to all four wheels via Merc's '4Matic+' AWD system, built around an electromechanically controlled clutch connecting the permanently driven rear axle (with locking diff) variably to the front axle.

The big news here is a more powerful rear motor – meaning you get more grunt whether you opt for the rear-wheel drive or this all-wheel drive.

In rear-drive form, that boosts your outputs from 200kW to 250kW, dropping the sprint to 100km/h to 5.6 seconds. In AWD guise, your new outputs are 365kW (up from 315kW) and 573Nm, and your sprint to 100km/h falls to 3.7 seconds.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 12.3L/100km, the E 63 S emitting 280g/km of CO2 in the process.

That's a pretty hefty number, but in line with this car's proportions and performance potential.

And Merc-AMG has gone to great lengths to minimise fuel use. As well as the standard 'Eco' stop-start function, in the 'Comfort' drive program cylinder deactivation becomes active, the system able to drop four cylinders anywhere between 1000 to 3250rpm.

There's no physical hint of half the cylinders leaving the party. The only clue is a blue icon on the dash indicating a temporary shift to V4 operation.

Despite all that effort, however, we saw a dash-indicated 17.9L/100km over a mix of urban trundling, highway cruising, and some spirited dynamic assessment.

Recommended fuel is 98 RON premium unleaded (although it'll run on 95 at a pinch), and you'll need 80 litres of it to fill the tank. That capacity translates to a range of 650km according to the factory claim, and 447km using our real world result.

This is where it starts to get weird. The rear-drive Zeekr X is fitted with a 61kWh LFP battery, which can accept up to 230kW DC fast charging, taking you from 10 to 80 per cent charged in just 18 minutes. Total claimed range is 405km.

The flagship AWD, though, charges at a slower rate. It gets a 66kWh NMN battery and can only be charged at 150kW, meaning the same charge takes 30 minutes. Zeekr is promising a 415km driving range between charges.

AMG's major goal with this upgrade of the E 63 S was to maintain its dynamic response and ferocious performance, but dial in the extra comfort customers had said they wanted.

So, the 4Matic+ AWD system has been fine-tuned for more smoothness as has the Comfort option in the dynamic set-up. But we'll investigate that shortly.

First, that 4.0-litre turbo V8 in the nose is claimed to slingshot this roughly 2.0-tonne sedan from 0-100km/h in just 3.4 seconds, and it feels every bit that fast.

With 850Nm available from 2500-4500rpm and nine gear ratios to help keep you operating in that Goldilocks band, mid-range thrust is monumental. And thanks to the bi-modal sports exhaust it sounds beautifully brutal.

The nine-speed auto's wet clutch, as opposed to a conventional torque converter, is designed to save weight and optimise response. And while some will tell you an auto with one input shaft is never going to be as fast as a dual-clutch with two, shifts are rapid and direct. The wheel-mounted shift paddles are larger and set lower, as well.

The AMG 'Ride Control+' suspension with multi-chamber air suspension and adaptive damping is amazingly good. The underlying set-up is by multi-links front and rear, and despite riding on big 20-inch rims wrapped with low-profile, high-performance Pirelli P Zero rubber (265/35 fr - 295/30 rr) the Comfort setting is incredibly... comfortable.

Slip into 'Sport' or 'Sport+' and the car immediately feels tauter but far less compliant and forgiving. An impression reinforced by the engine, transmission, and steering shifting to a more buttoned-down mode at the same time.

The standard dynamic engine mounts play a big part here. Able to make a soft connection for maximum comfort, but switch to a rigid link when required.

But no matter which mode you're in, the car is well damped and feels beautifully balanced in quick cornering. And the E 63 S's electro-mechanically-assisted variable-rate steering is progressive, feelsome, and accurate.

The 4Matic+ AWD system is built around an electromechanically controlled clutch connecting the permanently driven rear axle (with locking diff) variably to the front axle.

Torque distribution happens imperceptibly, the big V8 putting its power down emphatically, with various electronic systems tieing up the loose ends as you aim up for the next corner.

 There's even a 100 per cent RWD Drift mode available in the Race setting, but without a race circuit at our disposal this time around that'll have to wait for another time.

The optional ceramic brakes feature huge rotors and six-piston front calipers, and stopping power is immense. And the good news is they operate quickly but progressively at normal pottering around town speeds. No warming up required to get them in an optimal temperature zone (as can be the case with other ceramic set-ups).

Short answer? Pretty good, with some caveats.

I'm partial to a firmer ride. I find some Chinese car companies can feel like they get their suspension bits from Captain Snooze, such is the soft, pillowy ride served up. And to be honest, it makes me a little seasick at times.

The Zeekr is not like that. It has firmness dialled into the ride equation and can feel harsh at times, but also improves the drive experience, delivering connection and engagement at the cost of some sharpness on the wrong road. 

It's also faster than the model it replaces, but it's also one of those cars in which the real-life feeling doesn't quite match the on-paper promise.

This thing serves up supercar speed, but it doesn't feel like it from behind the wheel. Instead, the acceleration - especially from a rolling start - feels potent, but not biblical.

From a standing start it pauses for a moment, almost like an internal-combustion vehicle might, before delivering a quick (but not stratospheric) flow of power. None of that is a bad thing, by the way. Who wants their small SUV to accelerate like a supercar?

It's otherwise an entirely pleasant drive. The cabin is serene and quiet and it's a small car that doesn't feel like one. There's nothing light or tinny about the drive experience, instead there's a heft and quality.

The Zeekr X wears a maximum five-star ANCAP safety rating, earned in 2024, which means the long list of required active safety stuff is present and accounted for, all wrapped up in what Zeekr calls its 'Intelligent Driving Assist System'.

There are five cameras, five radars and 12 sensors, which is a crazy number for a car this small.

And this is also not a car in which I was desperately trying to figure out how to deactivate any of the active safety systems – save the overzealous over-speed warning – which is a win these days, too. 

There are also seven airbags, including a centre front airbag.

The Zeekr X is fitted with ISOFIX anchors on the rear outboard seats and top tether anchorages for all rear seating positions.

All AMG models sold in Australia are covered by Mercedes-Benz's five year/unlimited km warranty, with 24-hour roadside and accident assistance included for the duration.

Recommended service interval is 12 months or 20,000km, with pricing for a three-year (pre-paid) plan set at $4300, a $950 saving overall relative to its three year, pay-as-you-go 'Service Solutions' capped price program.

And if you're happy to fork over a little more up-front, there's a four-year service deal at $6300, and five years coming in at $7050.

Zeekr's coverage is an underwhelming five-year, unlimited-kilometres, while the drive battery is covered for eight-years or 160,000km. There’s five years' of roadside assistance thrown in, too.

Service intervals are 20,000km or 12 months, with five years' of ownership setting you back a hefty $3072; an average of $614 per workshop visit.

There are currently 16 Zeekr dealers in Australia - two of which are 'pop-up' sites rather than full retail centres.

Multiple locations in Melbourne, Sydney and Brisbane with the ACT, Adelaide and Perth also covered. Others include Geelong and the Sunshine Coast but so far you're out of luck in Tassie or the NT.
