Summary
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.

Mercedes-Benz AMG GT
"A racing car with street legal approval". Those are the words Mercedes-AMG uses to describe its GT R Coupe.
And even though I'm a forty-something, professional motoring journalist who's well aware of marketing speak when he reads it, the 15-year old in me was jumping around whooping and shouting: "Key! Gimme key to race car" at the launch of the updated Mercedes-AMG GT coupe which also included time in the more sedate GT C.
Well, that's like calling a Tiger Shark more sedate than a Great White, because the GT C still packs more than 400kW (550hp).
As will be the case with most buyers, my time in the Mercedes-AMG GT was spent entirely on the road, the closest we came to a racetrack was driving through Kilmore, and that one was for horses.
This was perfectly fine because you'll want to know just what these beasts are like to pilot on regular roads... roads where surfaces are far from perfect and the posted limits are hundreds of kilometres below the top speeds of these cars.

Verdict
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.
Mercedes-Benz AMG GT8.1/10
The AMG GT is better than a race car for the road because it offers all the comfort and luxury that is completely absent in a track car, yet retains superb dynamic ability – particularly the GT R.
As for the sweet spot, that's easy. The C Coupe offers the best of the S and R from a comfort and handling perspective, while being super quick for less money that the top grade R.
If you could have any of them, which Mercedes-AMG GT in the line-up would you pick? Tell us what you think in the comments below.
Design
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.
Mercedes-Benz AMG GT10/10
There is nothing not interesting about the design of the AMG GT with its long bonnet and low, wide stance. The look is not as dramatic as the SLS AMG, which went into retirement five years ago, nor does it have that supercar's 'gullwing' doors. But there's a clear family resemblance to it and also the iconic 300SL beauty from 1954.
If anything, the AMG GT is a meaner and sharper looking beastie, but still dripping in exotic styling with the hungry looking 'Panamericana' grille flanked by hornet eye headlights and enormous wheel guards that push up into the bonnet to form pontoons over which the driver peers.
It's hard to tell from the images if the AMG GT is big or small, but the dimensions don't lie. The AMG GT is 4551mm end-to-end, 2007mm wide for the GT R and GT C but 1939mm for the GT S (and between 1260mm and 1288mm tall depending on the grade, making it fairly long, wide and short in stature.
There are three grades to choose from - the GTS, GT C and GT R – which all come as coupes, while only the GTC is available as a soft-top roadster, as well.
I can't think of a convertible which doesn't look better with the roof down than with it up and the GT C is no exception to this rule. The open top suits this cruiser's look perfectly.
Telling the three grades apart is easy if you know what to look for: the GT S is a 'narrow body', the GT C has wider rear guards and the GT R has wide rear and front guards.
From behind there's a smoother rear treatment to the S with no wide black vent between the tail-lights, while the GT C has vents behind the rear wheels and the GT R has the most aggro look with the giant diffuser and a central tailpipe.
Exterior styling has stayed the same save for the new LED headlights, wheels and paint colours, but it's the cabin where most of the design changes have taken place.
There's the new steering wheel with drive mode dials and a redesigned centre console with buttons configured in a V-shape which according to Mercedes-AMG is a nod to the V8 engine.
I'm not convinced by the restyling of the console, which didn't suit me ergonomically. It seems to centre around the two cupholders, places the shifter awkwardly rearwards of the media controller and puts the traction control button directly under the driver's elbow. The black piano plastic in the GT R also became smudged with fingerprints quickly.
Practicality
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.
Mercedes-Benz AMG GT6/10
All AMG GT Coupes and Roadsters have two doors and two seats. If you need seating for more there's the AMG GT 4-door which can fit five adults (well, four comfortably) and competes with the Porsche Panamera.
So, if it's just you and a significant other you'll be happy to know the AMG GT cockpit is spacious and even at 191cm tall and with the same wingspan I had more than enough head, shoulder, elbow and legroom.
Cabin storage is limited to a pair of cupholders, a small centre console bin and door pockets just wide enough for a small bottle of water.
Boot space in the Coupe is 175 litres and 165 litres in the Roadster. That was just enough room for the two airline overhead luggage-sized wheelie bags belonging to myself and co-pilot.
As for charging and power on board there are three USB ports and one 12-volt outlet.
Price and features
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.
Mercedes-Benz AMG GT8/10
The entry point into the three model range is the GT S Coupe with its $311,142 list price.
Stepping up to the GT C will cost $329,843 for the Coupe and $355,242 for the Roadster, while the GT R king of the castle commands a list price of $361,042.
Standard features on the S include nappa leather upholstery, heated and power-adjustable seats, AMG Performance steering wheel, panoramic sunroof, 10-speaker Burmester sound system, a 10.25-inch touchscreen with sat nav, Apple CarPlay and Android Auto, 'Mercedes Me' connect system, a 12.3-inch virtual instrument cluster, LED headlights, plus alloy wheels (staggered 19-inch at the front and 20-inch at the rear) with a matt black finish.
You'll see all these S features on the GT C along with more in the form of AMG Performance seats, AMG Performance steering wheel clad in 'Dinamica' microfibre, heated and ventilated seats and staggered 19-/20-inch alloys in titanium grey.
The GT C Roadster has identical features but adds a neck heater, which works surprisingly well.
The GT R comes with the GT C's features and brings its own in the form of the AMG 'Interior Night' package, a carbon-fibre roof, static rear wing and yellow brake calipers.
Porsche's 911 GT3 is a good rival for the AMG GT R, but undercuts it by about $35K, while a Jaguar F-Type SVR is $297,242 and Audi's R8 tops out at $425,500 for the Spyder.
So, is the AMG GT good value? Sure is, when you consider what you're getting relative to what the competitors are offering.
Under the bonnet
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.
Mercedes-Benz AMG GT9/10
All AMG GTs have a 4.0-litre twin-turbo V8 with three states of tune: in the S it makes 384kW/670Nm; in the C it produces 410kW/680Nm; while the output in R is 430kW/700Nm.
A seven-speed dual-clutch automatic transmission is used in all three grades.
All three grades have top speeds of more than 300km/h (318 in the R Coupe; 317km/h in the C Coupe; 316km/h in the C Roadster and 310km/h in the S Coupe) and 0-100km/h times of less than four seconds (R -3.6s, C - 3.7s, S - 3.8s).
Before you start wondering why the R costs $30K more to go one kilometre per hour faster than the C we need to talk about the hardware under the cars that makes the top-grade AMG GT worth the extra money in the section below.
Efficiency
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.
Mercedes-Benz AMG GT7/10
This might surprise you, but the official combined fuel consumption of the AMG GT S is 9.5L/100km, while the GT R's is 11.4L/100km, and the GT C's is 11.5L/100km.
The best combination of driving over motorways and country roads for me on this launch was in the GT R, and after a couple of hundred kilometres the trip computer told me the car was using an average of 12.9L/100km.
Driving
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.
Mercedes-Benz AMG GT9/10
The only grade missing at the launch of the updated AMG GT was the S Coupe. So, while I'm sure it's darn good, I can really only comment about the driving experience of the R Coupe and the C in Coupe and Roadster forms in which we devoured hundreds of kilometres.
First, the R and C both have unique characters that go beyond just differences in horsepower.
The GT C uses the front axle set-up of the GT S with its aluminium double wishbone suspension, anti-dive, coil springs and stablisier bar offering a more supple and cushioned ride, and combines this with the rear axle of the GT R with its rear-axle steering and more pinned down dynamic focus.
The GT R's front axle is also aluminum double-wishbone but comes with braking torque support, mechanically stepless adjustable coil springs, adaptive dampers and an anti-roll bar.
So, while the GT C and GT R feel different to pilot, it's not night-and-day different... more early summer morning sunrise, and midday sun beating down different, if you know what I mean.
See, while the GT C feels just as quick, it's a far more comfortable and easier car to drive on course-chip bitumen and pock-marked Australian roads. The ride while rolling on 265/35 R19 rubber at the front and 305/30 R 20s at the rear is surprisingly pleasant.
Country road corners beckoned on our journey out of Melbourne and the GT C Roadster I set out in responded superbly. That front end felt light, soft and but pointable. What was immediately apparent was how wide the car is, and it felt like the GT C needed every millimetre of the narrow Aussie lanes.
Top down there was almost zero air turbulence in the cabin and while I kept an eye out for the scuttle shake that can come with a convertible, I barely noticed anything along those lines with those short thick A-Pillars holding firm.
Also holding firm was the GT C's rear end which squatted and held tight in the corners even with getting on the gas the roadster stayed composed.
Roof up, most road noise was shut out, well it was hard to hear anything over the bellow of that V8.
The GT C Coupe would be my pick of the AMG GT family and not just because of that smidge of extra boot space. The hardtop just bolsters the overall rigidity of the car and made it feel tauter.
The GT R is a step up in price, grunt and dynamic ability, but it's asking for a higher level of commitment in terms of livability.
The ride on its firmer suspension and 275/35 R19 rear tyres and 325/30 R 20 front rubber makes the GT R more brutal than most people would be happy to live with, I think.
But in return you are getting close to that "racing car with street legal approval" positioning, because the GT R is astounding in its balance, handling, grip and the connection it offers with the driver.
Truly engaging and almost wasted on a regular road, but why it's not quite a race car is that the cabin is dripping in luxury from the beautiful and supportive standard seats, to the leather upholstery and digital instrument cluster.
Safety
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.
Mercedes-Benz AMG GT9/10
Coming standard on all AMG GTs is AEB, blind spot warning, lane keeping assistance, traffic sign recognition and adaptive cruise control.
All cars in the line-up come fortified with airbags, including a knee bag for the driver, side bags for the driver and passenger (combined thorax/pelvis bag), front airbags and window bags (Coupe only).
Front and rear cameras and auto parking make life easy, and while there's no spare wheel there is an inflation kit for temporary puncture repair.
A two-seater car the AMG GT doesn't have anchor points for child seats.
The AMG GT has not been assessed by ANCAP or Euro NCAP for its crash safety performance.
Ownership
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.
Mercedes-Benz AMG GT7/10
The AMG GT has a three-year unlimited/kilometre warranty and along with BMW and Audi it's short compared to the coverage offered by more affordable brands.
Servicing is recommended at 20,000km/12-month intervals. Mercedes-AMG offers a three-year plan which costs $3750 up front or you can pay as you go with capped price servicing at $800, $1000 and $2950 for each respective year.
