Summary
Mercedes-Benz E53
The E53 range broke new ground for Mercedes-AMG when it debuted in 2018. Not only was it the E-Class large car’s new ‘entry-level’ performance option, but it was also Affalterbach’s first model to combine an inline six-cylinder engine with a mild-hybrid system.
Needless to say, the E53 was an intriguing prospect at the time, and now it’s come back into frame following a midlife facelift, which doesn’t appear to mess with what turned out to be a rather successful formula.
And with an E63 S flagship performance option still not available in the two-door E-Class line-up, the E53 is as good as it gets. But as you’ll find out when you read this review of its Coupe body-style, that is actually really great news. Happy reading.

KTM X-Bow
I know what you're thinking: "How is this thing legal?" And to be honest, somewhere between a rock flung from the tyre of a passing car colliding with my forehead like it had been fired from a pistol, and the pouring rain lashing my exposed face like a damp cat-o'-nine-tails, I'd begun wondering the same thing.
The answer is barely. The product of a years-long fight to overcome our import rules, this madhouse KTM X-Bow R is now finally free to roam Australian roads and racetracks - though, with sales capped at 25 per year to comply with the Specialist Enthusiast Vehicle Scheme.
The price? A slightly eye-watering $169,990. That's quite a lot, and places the X-Bow R miles above its closest lightweight, carbon fibre-tubbed competitor, the Alfa Romeo 4C ($89,000).
But then, the KTM X-Bow R is unlike anything else on the road today. Part super bike, part open-wheeler and all mobile madness, the 'Crossbow' is fast, furious and completely insane.
Expect no doors, no windscreen, no roof. On-board entertainment is limited to the turbo whistling behind your head, the car's standard safety list is as barren as the interior and the climate control is dependent on the temperature of the wind that's smashing into your exposed face.
And we couldn't wait to take it for a spin.

Verdict
Mercedes-Benz E538.3/10
As it turns out, the automotive world really doesn’t need an E63 S Coupe, because the E53 Coupe really does give you all you’ll ever need.
Simply put, the E53 Coupe’s balance of performance and luxury is bang on, while an E63 S Coupe would arguably prioritise one too much over the other.
Indeed, if you’re interested in a ‘relatively affordable’ grand-tourer that can get up and go when required, you could do a lot worse than the E53 Coupe.
KTM X-Bow6.8/10
Okay, so rain is not your friend. Neither is brutal sunshine, strong winds or any speed bump anywhere. There are probably a handful of times you'll want to drive it, and when you do you will definitely get hit in the face with rocks and bugs, and spend most of your time wondering just how the hell this thing is legal.
And yet, we are hopelessly, head-over-heels in love with it. It's an absolute weapon on a track, a joy on anything even resembling a twisting road and it is one of the few genuinely unique cars on the road today. And the fact it exists at all is a cause for absolute celebration.
Does the KTM X-Bow R's purity of purpose appeal to you, or is its performance focus just too narrow? Tell us what you think in the comments below.
Design
Mercedes-Benz E539/10
The E53 Coupe already had an alluring exterior design, but in facelifted form, it looks even better.
The big changes are up front, where the E53 Coupe now has Mercedes-AMG’s signature Panamericana grille insert, with the multi-louvre aesthetic previously the reserve of its ‘63’ models.
In fact, the entire fascia has been redesigned, with the grille flipped upside down, while the Multibeam LED headlights are flatter and therefore angrier. Naturally, the bonnet and bumper have been tweaked to match, with the former featuring strong powerdomes.
Around the swoopy sides, a sporty set of black 20-inch alloy wheels is new, matching the window trim, while the only differences at the rear are the fresh graphics of the LED tail-lights.
Yep, the E53 Coupe still has a subtle bootlid spoiler and a prominent diffuser insert, which integrates the quad round tailpipes of its sports exhaust system.
Inside, the midlife facelift really makes itself known with its new flat-bottomed steering wheel with capacitive buttons and haptic feedback. This set-up is… fiddly, with presses often confused for swipes, so it's not exactly a step in the right direction.
And that’s particularly annoying because these controls are used for the carryover 12.3-inch touchscreen and 12.3-inch digital instrument cluster, which are now powered by Mercedes’ MBUX multimedia system, which bundles in Apple CarPlay and Android Auto support.
While now familiar, this set-up remains the benchmark in nearly all regards and is therefore a brilliant upgrade for the E53 Coupe, thanks to its speed and breadth of functionality and input methods, including always-on voice control and a touchpad.
Materials-wise, Nappa leather upholstery covers the seats and steering wheel as well as the armrests and door inserts, while Artico leatherette trims the upper dashboard and door shoulders.
Conversely, hard, shiny plastics adorn the lower door panels. Given that ‘cow hide’ and other soft-touch materials are used on most other surfaces, it’s unusual that Mercedes-AMG didn’t go the whole way.
Elsewhere, open-pore wood trim features prominently, while metallic accents brighten things up alongside the sporty stainless-steel pedals and smile-inducing ambient lighting.
KTM X-Bow8/10
The X-Bow R is built for purpose in the most wonderful of ways. From the visible suspension components to the rocket-style exhausts, to the stripped-bare interior, it's fairly obvious that form came a distant second to function in the X-Bow's design process.
And, for us at least, that's a tremendous thing. It looks raw and visceral, and a bit like Harvey Dent post-fire - you can see all the normally hidden components doing their thing. It's mesmerising.
Practicality
Mercedes-Benz E538/10
Measuring 4835mm long (with a 2873mm wheelbase), 1860mm wide and 1430mm tall, the E53 Coupe is a genuinely large car, which is great news for practicality.
The boot has a pleasing cargo capacity of 425L, but it can be increased to an undisclosed volume by stowing the 40/20/40 split-fold rear bench via the handy manual release latches.
It’s worth noting that while the aperture is wide, it’s not tall, which could be a problem for bulkier items alongside the tall load lip, although two tie-down points are on hand for securing loose items.
However, what really impresses is the amount of space inside. While the front sports seats are comfortable, the two rear passengers are in for the bigger treat, with room plentiful, mercifully ending the argument of who gets stuck in the uncomfortable second row.
Behind our 184cm driving position, there’s two inches of legroom as well as an inch of headroom, although toe-room is almost non-existent.
Being a four-seater, the E53 Coupe divides its rear occupants with a tray that contains two cupholders, while they also have access to two side cubbies and a small central cubby with two USB-C ports. This cubby is positioned between the air vents at the rear of the centre console.
And yes, even child seats can be fitted, with two ISOFIX and two top-tether anchorage points available should they be required. In fact, the long front doors make this task less challenging, although those big doors do become problematic in tight carparks.
All of that’s not to say occupants in the first row aren’t treated well, because they are, with the centre console’s cubby featuring two cupholders, a wireless smartphone charger, a USB-C port and a 12V power outlet.
Other storage options include the decently sized central bin, which contains another two USB-C ports, while the glovebox is also of a decent size, and then there’s the overhead sunglasses holder.
KTM X-Bow5/10
Short answer? It's not. People are unlikely to test drive an X-Bow R and start looking for cupholders and storage space, but if they did, it wouldn't take long.
Aside from the twin seats, a four-point racing harness, a high-mounted gearshift, a pull-lever handbrake, and detachable steering wheel, the cabin is as bare as Old Mother Hubbard's cupboard.
Luggage space is limited to what you can carry in your pockets (though wearing cargo pants will help) and even getting in and out of the thing takes some fleet-footed antics. With no doors you need to literally jump in. And the side sills are only rated to 120kg, so heavier types will need to avoid stepping on them at all, and instead attempt a kind of running leap into the cockpit.
Price and features
Mercedes-Benz E538/10
Priced from $164,800 plus on-road costs, the facelifted E53 Coupe is actually a staggering $14,465 more affordable than its predecessor.
But if you’re not a fan of its body-style, the $162,300 E53 sedan (-$11,135) and $173,400 E53 Cabriolet (-$14,835) are also available.
Either way, standard equipment not already mentioned includes metallic paintwork, dusk-sensing lights, rain-sensing wipers, power-folding side mirrors with heating, keyless entry, rear privacy glass and a power-operated bootlid.
Inside, push-button start, a panoramic sunroof, satellite navigation with live traffic, digital radio, a 590W Burmester surround-sound system with 13 speakers, an augmented reality (AR) head-up display, a power-adjustable steering column, power-adjustable front seats with heating, dual-zone climate control and an auto-dimming rearview-mirror feature.
Direct rivals for the E53 Coupe are non-existent, with the closest being the smaller – and therefore much more affordable – BMW M440i Coupe ($118,900) and Audi S5 Coupe ($106,500). Yep, it’s a unique offering on the market, this Merc.
KTM X-Bow7/10
Keen readers of this site will recognise this as the area where we outline the many and varied features that come along with a normal new car purchase, but that's just not going to work this time. In fact, it'll be considerably easier to talk about what's missing, so let's start with the obvious: doors, windows, roof, windscreen. All conspicuously absent from this weird and utterly wonderful X-Bow.
Inside, you'll find two thinly (and we mean thin - we've seen thicker contact lenses) padded seats fixed into the tub. You'll also find push-button start, a digital screen reminiscent of those found on motorbikes (KTM is an Austrian-based motorcycle company, after all) and a pedal box that slides backward and forwards to offset the height of the pilot. Oh, and that steering wheel can pop off to make getting in and out easier.
Climate control? Nope. Stereo? Nope. Proximity unlocking? Well, kind of. With no doors, you'll always find it unlocked when you enter its proximity. Does that count?
But what it does have is a turbocharged two-litre engine. And in a car that weighs a sprightly 790kg, that means it's quick, pulling like a rabid sled dog in every gear, rear tyres chirping with every change.
Under the bonnet
Mercedes-Benz E539/10
The E53 Coupe is powered by a 3.0-litre inline six-cylinder petrol engine that produces a hearty 320kW of power at 6100rpm and 520Nm of torque from 1800-5800rpm.
The unit in question has one traditional turbocharger and an electric-powered compressor (EPC), which is available at engine speeds up to 3000rpm and can spool up to 70,000rpm in just 0.3 seconds for instantaneous punch.
But that’s not all, because the E53 Coupe 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 temporary electric boost.
Mated to a nine-speed torque-converter automatic transmission with redesigned paddle-shifters, and Mercedes-AMG’s fully variable 4Matic+ all-wheel-drive system, the E53 Coupe sprints from a standstill to 100km/h in a handy 4.4 seconds.
KTM X-Bow8/10
The X-Bow R's power comes from an Audi-sourced, turbocharged 2.0-litre engine, paired with a VW Group six-speed manual transmission (and one of the stubbiest gearsticks in existence). That mid-mounted marvel produces 220kW at 6300rpm and 400Nm at 3300rpm, and ships it off to the rear tyres with the assistance of a Drexler mechanical limited-slip differential.
Thanks to its lithe and lightweight body, that's enough to propel the X-Bow R from 0-100km/h in a blistering 3.9 seconds, and on to a top speed of 230km/h.
Efficiency
Mercedes-Benz E537/10
The E53 Coupe’s fuel consumption on the combined-cycle test (ADR 81/02) is 9.3L/100km, while its carbon dioxide (CO2) emissions are 211g/km.
Given the performance on offer, both claims are pretty good. And they’re made possible by the E53 Coupe’s 48V EQ Boost mild-hybrid system, which has coasting and extended idle-stop functionality.
That said, in our real-world testing, we averaged a more realistic 12.2L/100km over 146km of driving, although the launch test route only involved high-speed country roads, so expect a higher result in metropolitan areas.
For reference, the E53 Coupe has a 66L fuel tank, and it will only drink more expensive 98RON premium petrol.
KTM X-Bow7/10
KTM lists the X-Bow R's claimed/combined fuel figure at 8.3 litres per hundred kilometres (though we were managing mid-12s after an, ahem, very spirited test), with emissions pegged at 189 grams per kilometre.
The X-Bow R is also fitted with a 40-litre fuel tank, accessed via a side-mounted inlet. Instead of a fuel gauge, expect a digital reading showing how many litres you have left.
Driving
Mercedes-Benz E538/10
If an E53 Coupe was your daily driver, you’d be very happy, because its balance of comfort and performance is just about as good as it gets.
Stick the boot in and the engine responds with a level of enthusiasm that only electrification can provide. Not only does the ISG provide timely thrust, but the EPC helps the E53 Coupe reach its maximum torque, although it has to work harder for peak power.
That said, despite the addition of the EQ Boost system and the EPC, the E53 Coupe still feels like a proper Mercedes-AMG model, staying true to the high-performance mantra while offering a different approach.
Critically, all the drama is there, as it charges towards the horizon with intent as the transmission swaps gears smoothly, providing relatively quick shifts and revving on the down changes when required. It all adds up to a properly exciting drive.
However, it’s the E53 Coupe’s sports exhaust system that’s likely to command all the attention with its crackles, pops and overall booming soundtrack in the Sport mode. It can also be manually engaged in any mode by pressing a button in the centre console.
And given the E53 Coupe’s 4Matic+ system is fully variable, it offers plenty of grip when briskly accelerating and enjoying the soundtrack, but its rear end can still step out briefly when cornering hard.
Speaking of handling, the E53 Coupe goes around corners surprisingly well, defying its large dimensions and considerable 2021kg kerb weight by exhibiting strong body control.
Coming into bends, the E53 Coupe can also lean on its sports brakes, which pull up with absolute confidence.
And when you’re guiding the E53 Coupe through the twisty stuff, the electric power steering comes to the fore, with its speed-sensitivity and variable ratio.
The steering set-up is somewhat disappointing at times, however, with the feedback not quite up to the level of a proper performance car.
That said, it is quite direct and feels meaty in hand – two traits that are necessary for success – with this heft increased in the Sport drive mode. Comfort is where it’s at, though, if you ask me.
That said, the E53 Coupe’s suspension uses air springs and adaptive dampers to make it a comfortable cruiser.
Sure, this set-up’s tune does prove to be a little firm on lower-quality country roads, with most bumps and lumps felt by occupants, but on well-maintained highways and city roads, it’s got suitable levels of smoothness.
In keeping with this luxurious feel, the E53 Coupe’s Noise, Vibration and Harshness (NVH) levels are pretty damn good, with tyre roar and wind whistle easily missed while enjoying its aforementioned Burmester sound system.
KTM X-Bow9/10
It couldn't be more Fast and Furious if it had Vin Diesel growling under its (non-existent) bonnet. We have technically driven faster cars, but we have never driven anything that feels quite so fast as this utterly insane X-Bow R.
Climb in, strap into the four-point harness and select first via the surprisingly easy-to-manage gearbox and clutch set up, and, at slow speeds, wrestle with the dead weight of the completely unassisted steering, and it's immediately clear that this is a driving experience like nothing else currently road-legal in Australia. Even at walking pace, the X-Bow R feels poised for an assault on the future, and it attracts attention on the road like nothing else we've ever driven.
Its road-scraping ride height and diminutive dimensions make tackling traffic an intimidating prospect, with regular hatchbacks suddenly taking on truck-like proportions and actual trucks now looking like passing planets. There's a constant concern that you're sitting well below the traditional blind spot, and that you could be crushed at any moment.
Combine all that with the bad weather that cursed our final day of testing, and the X-Bow R is all sorts of watery hell. It is truly homicidal in the wet, too, with the back end breaking grip at the slightest provocation. And the turbocharged 2.0-litre offers plenty of that.
But on a sunny day, and on the right road, it's pure driving bliss. The acceleration is brutal, the grip endless and the Audi sourced gearbox an absolute treat. And it pulls in every gear, tackling 35km/h corners in third and absolutely blasting out the other side.
Cornering is scalpel sharp, and the steering - so heavy at slow speeds - is light and efficient at pace, requiring only the most minuscule of movements to bite into a bend.
It is anything but perfect in the city, and even a light sprinkling of rain will have you seeking shelter (and a refund), but on the right road, on the right day, there are few if any cars that offer the kind of razor-sharp thrills and intoxicating excitement of KTM's monstrous X-Bow R.
Safety
Mercedes-Benz E539/10
ANCAP awarded the fifth-generation E-Class sedan and Estate its maximum five-star rating in 2016, although it doesn’t apply to the E53 Coupe, due to its differing body-style.
That said, advanced driver-assist systems still extend to autonomous emergency braking with pedestrian detection, lane-keep and steering assist (including emergency), adaptive cruise control with stop and go functionality, traffic-sign recognition, driver-attention alert, high-beam assist, active blind-spot monitoring and cross-traffic alert, tyre-pressure monitoring, park assist, surround-view cameras and front and rear parking sensors.
Other standard safety equipment includes nine airbags, anti-skid brakes and the usual electronic traction and stability-control systems.
KTM X-Bow5/10
Next to none. There is no ABS, traction or stability control. No airbags, powered steering or ISOFIX attachment points, either. If you break traction (which, in the wet, is more than a little bit likely) it'll be up to you to ensure you straighten up again. Helpfully, there's a ton of grip from the Michelin Super Sport tyres.
As part of the compliance program, Simply Sports Cars (the company responsible for introducing the X-Bow R) actually crash tested two cars in Europe, and raised the ride height by 10 millimetres. Oh, and there's now a seatbelt warning sign, too.
Ownership
Mercedes-Benz E538/10
Like all Mercedes-AMG models, the E53 Coupe comes with a five-year/unlimited-kilometre warranty, which is currently the benchmark in the premium market. It also comes with five years of roadside assistance.
Better yet, the E53 Coupe’s service intervals are rather long, at every year or 25,000km – whichever comes first.
It’s also available with a five-year/125,000km capped-price-servicing plan, but it costs an expensive $5100 in total, or an average of $1020 per visit, with the E53 Coupe’s fifth trip charging $1700 alone. Ouch.
KTM X-Bow5/10
The X-Bow R is covered by a two-year, unlimited-kilometre warranty, and while service prices aren't capped, Simply Sports Cars estimates an average serve cost at about $350.
