Lexus RC F vs KTM X-Bow

What's the difference?

There’s so much to like about the Lexus RC F EP3. A glorious atmo V8 soundtrack, sharp dynamics, plus loads of standard features and safety tech in a beautifully engineered four-seat coupe package. It can’t match the turbos for mid-range thump, and if you need practicality look elsewhere, but it’s the type of performance car we’ll be looking back at in years to come as one of the last to proudly hold its head above a rising tide of turbos, hybrids, and electric hot rods. 

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.

At just over 4.7m long, a bit more than 2.0m wide and less than 1.4m high, the RC F has a classically macho wide coupe stance with a distinctive Lexus twist. 

In a late 2019 refresh the RC F was upgraded with suitably jagged single-piece, LED headlights and an even wider version of Lexus’ signature ‘spindle grille’ featuring a new mesh pattern.

Pumped up guards sitting over the standard 19-inch BBS rims feature gills behind them to help smooth airflow around the front of the car, stabilise it overall, and exhaust cooling air flowing around the brakes.

A revised rear diffuser is now body coloured, the stacked-at-an-angle quad exhaust pipes are a Lexus ‘F’ hallmark, stainless steel window trims are now dark rather than bright thanks to a thicker oxide film covering, and the LED tail-lights feature a new L-shaped insert.

Of course, a car’s looks are always subjective, but I think the RC F’s interior is super cool, combining long, flowing graphics on the seats and doors, with rounded, multi-level sections and brushed metal finishes across the dashboard.

The racy instrument binnacle tips its hat to classic sports cars of the ‘60s, the analogue clock between the central air vents could come off as cheesy, but actually looks great, and the large multimedia screen set ‘rear-of-stage’ at the top of the dash is subtly integrated.

True to form, this Lexus is beautifully finished with an obvious eye to design detail and manufacturing quality. Which makes its biggest failing all the more irritating. 

The ‘Remote Touch’ control pad behind the gearshift in the centre console managing settings in the media system is hateful.

Operating in similar fashion to a laptop mousepad (only worse) despite available adjustments for speed/sensitivity, even on its most benign setting it is maddeningly over-reactive and inaccurate. Lexus should just put its hand up, say “My bad” and retire it, yesterday.

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 is unlikely to be high on the priority list for anyone shopping for a car like this, but comfort and convenience certainly will be.

And the RC F delivers just that for its front seat passengers, providing lots of space, as well as numerous storage options, including long door bins with room for smaller bottles, two cupholders in the centre console, a large, lidded storage box/armrest between the seats (housing twin USB-A ports, an aux-in jack, and a 12V socket), as well as a decent glove box.

But that space we were just talking about pretty much evaporates when you move to the back. This is a classic ‘2+2.’ The electric folding and sliding front seats make access okay, however, sitting behind the driver’s seat, set for my 183cm height, headroom is tragic, legroom is tight, and toe room is bad. 

So, let’s assume it’s a kids-only area, and once ensconced back there, they’ll appreciate a fold down centre armrest, two cupholders between the seats (with a roll-top cover), and adjustable air vents. But there isn’t a USB point in sight which may lead to friction when devices lose charge, or a plug-in negotiation with front-seaters. 

Lexus claims a modest boot volume of 366 litres (VDA) and it’s important to note that although there’s a ‘ski-port’ door to accommodate lengthy things (like skis?) the rear seats don't fold down. So, flexibility is limited, although there are tie-down hooks at each corner of the floor to help secure tricky loads.

The Lexus RC F is a no-tow zone, and don’t bother looking for a spare of any description, a repair/inflator kit is your only immediate option. Good thing roadside assistance is included in the warranty package.

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.

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.

The Lexus RC F is powered by the latest iteration of the brand’s (2UR-GSE) 5.0-litre, naturally aspirated V8 engine.

Featuring exotic touches such as a dual variable valve timing (with electric actuation on the inlet side), dual-length intake runners, forged connecting rods, titanium valves, and the ‘D-4S’ control system (combining port and direct-fuel injection) it produces 351kW (471hp) at 7100rpm, and 530Nm from 4800-5600rpm.

Drive goes to the rear wheels via an eight-speed (torque converter) automatic transmission with a new ‘AI-Shift’ control designed to adapt to the driver’s style and shift drive modes more effectively, as well as a Torsen mechanical limited-slip differential.

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.

Claimed fuel economy for the combined (ADR 81/02 - urban, extra-urban) cycle is 11.1L/100km, the V8 emitting 254g/km of CO2 in the process.

In our week with the car, over a combination of city, suburban and freeway conditions (including some enthusiastic B-road running) we recorded an average of 12.8L/100km, which, while not exactly frugal, is still impressive for a V8, performance-focused coupe. 

Minimum fuel requirement is 98 RON premium unleaded, and you’ll need 66 litres of it to fill the tank.

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.

A performance car should excite the senses, but the RC-F leans on one a little harder than the rest… hearing.

With the addition of launch control in last year’s update the big V8 will reliably slingshot you from 0-100km/h in just 4.5sec, which is no mucking around quick. But it’s the combination of raucous induction noise, furious mechanical roar, and bellowing titanium exhaust that add extra drama to the experience.

Fact is though, while maximum torque of 530Nm is not to be sneezed at, that number is only available from 4800-5600rpm. Although the RCF starts to get into its stride at about 3000rpm, the twin-turbo BMW M2 CS smashes it for mid-range punch with its 550Nm on tap from just 2350rpm.

So, in everyday, even mildly enthusiastic driving, the RC F sounds amazing, and don’t get me wrong, this is a proper performance car, but it doesn’t have the low-down, kick-in-the-pants grunt of its turbocharged six and eight cylinder competitors.

Linear power delivery, and the crisp throttle response only a naturally aspirated engine can deliver go some way to evening things up, however, and there are multiple systems to help tune the drive experience to your exact preference.

‘Drive Mode Select’ offers five settings (Eco, Normal, Sport S, Sport S+, and Custom).

Eco lowers engine output, dampens the throttle, and dulls the air-con in the name of fuel efficiency and reduced emissions. But you’re not buying this car to save the planet, so don’t touch that button, Sport S is the sweet spot (and save Sport S+ for track days).

Quick gearshifts from the eight-speed auto (particularly using the wheel-mounted paddles), that rapid throttle response, and nice steering feel work seamlessly together to deliver a satisfying backroad experience. Sport S holds gears longer on the way up the ratios, and is quicker to shift on the way back down.

In a more civilised mode, with eight gears to play with, freeway cruising is relaxed, especially given the top two ratios are overdriven.

The ‘Adaptive Variable Suspension’ offers Normal and Sport S modes, and here normal is the go. The basic set-up is double wishbone front, multi-link rear, and Lexus says the SACHS-developed AVS shocks can adjust damping force across a range of 30 levels. But even in the default Normal setting the ride is firm.

According to Lexus, the standard Michelin Pilot Sport 4S tyres (255/35 fr / 275/35 rr) have been tailored specifically to the RC F and they grip hard, keeping the 1715kg coupe planted in quick corners. But their narrow profile no doubt contributes to the car’s less than limo-like feel around town.

Then the ‘Vehicle Dynamic Integrated Management’ system fine tunes the car’s stability control in Sport S+ and Expert modes. Expert only happens when you’re in Sport S+ and turn the stability control off. So again, best to go full racer at the circuit, and we didn’t explore VDIM this time around.

The electrically-assisted steering is not only accurate (the strength of the steering rack bushing has been increased by 150 per cent to boost response), but the wheel itself feels great, and the huge (380mm) Brembo carbon ceramic brakes are mega (working well from cold unlike some other carbon set-ups).  

Under the heading of notable mentions, the digital instrument cluster is inspired by the V10-powered Lexus LFA supercar, switching between a blue economy indicator ring in Eco mode, a standard tachometer and digital speedometer in Normal, a white and red cluster in Sport S, and orange in SPORT S+ (with three-stage upshift indicator lights).

Plus, you can also switch between racy functions such as a lap timer and G-force display, and soft-trim knee pads on the sides of the front centre console improve comfort and seating stability if you’re having a crack.

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.

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.

The standard Lexus warranty in Australia is four years/100,000km, which outscores the likes of Audi and BMW on duration (both at three years) but trails on kilometres (both offering unlimited km).

Then there’s Merc, which has gazumped all the luxury players with five year/unlimited km cover. Plus, there’s the fact that the mainstream market standard is now five years/unlimited km, with some at seven years.

To balance the scales, the ‘Lexus Encore Privileges’ program provides 24-hour roadside assistance for the duration of the warranty, as well as access to owner events and special offers.

Service is scheduled for 12 months/15,000km (whichever comes first), and Encore capped price servicing is available for a three year period, averaging $595 annually, for an all-in cost of $1785.

A Lexus loan car is provided while your pride and joy is in the workshop, or a pick-up and return option (from home or office) is available in some instances. You’ll also receive a complimentary wash and interior vacuum. Nice.

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.
