Driven: KTM X-BOW R

More of the 'right stuff' for KTM's sensational track toy



'Ready to Race?' As messages from your car go, they don't come more provocative. It's what pops up on the console of your KTM X-Bow every time you start it up and the invitation can only be answered one way.


The regular X-Bow is hardly lacking in track potential, but KTM felt it could do with some more. More power. More grip. More competence. More fun. So the Austrian motorbike maker has developed this, the X-Bow R, the capital R standing for - you guessed it - Racing. So when you thumb the info screen into life on this little baby, you can answer its question with a double affirmative.

None of you are going to be shocked that KTM has boosted the power of the car's Audi-sourced 2.0-litre FSI turbocharged four; it is, after all, an engine with massive tuning potential. What might surprise you is that KTM has only pumped it up to 300bhp when some of its full-on race cars are zipping about with 370bhp. Nevertheless, the R is 60bhp more potent that the standard car, representing a 25% increase, so it's not like the engineers have been mean.


The power hike isn't just down to some white-coated boffiny types fiddling with the engine management system, although some of that has been done. The block's been strengthened, the turbo's bigger and the injection system has been revised. And while the workshop guys were in the mood for re-engineering, they not only dropped the engine in the chassis by 19mm to lower the centre of gravity, they also attached the engine mount torque tube directly to the carbonfibre monocoque - rather than the rear subframe as previously - to help make the back end more rigid and therefore better able to put down the power coming out of corners.

Make a car more grunty and you also need to adjust the chassis settings, in this case revised dampers and stiffer springs. There are some aerodynamic improvements, too, but the various winglets and reprofiled spoilers aren't standard on the R, they're options that you could fit to your current X-Bow if you were that way inclined. KTM sells a variety of aero packages, and it makes more sense to buy your air tamers this was rather than individually, because you'll save yourself a small fortune.

The X-Bow continues to look like a Transformer that's halfway through changing from a car into an earth-saving robot, all sharp angles and panels that look like body armour. Pretty it ain't, but you can't fault it for visual drama. And if you're not fully familiar with the X-Box formula, anything that looks like carbonfibre is carbonfibre, including its chunky central monocoque.


Clearly working on the theory that if you ask someone 'Ready to Race?' then you'd best provide them a venue to do just that, KTM has invited PistonHeads along to the newly rejuvenated Spielberg Ring in Austria; actually the neat little circuit has a new name, the Red Bull Ring, on account of that's who stumped up the considerable amount of cash for the revamp and who hosted the opening party only a couple of days ago. Several variations on the X-Bow R theme are available for us to play with, including a race version with the full aero treatment and slicks, a couple of bitsas with some aero parts and Toyo grooved trackday rubber, and a standard R running on fully treaded Michelin Pilots.

With a bunch of journalists from all around Europe to get through, KTM has devised an itinerary that includes driving all versions of the R in an order they've devised. In an ideal world I'd have preferred not to start with the racer, but at least the other cars have been arranged for me in descending order.


Starting the X-Bow is a palaver. First, remove steering wheel. Then step over broad sections of undertray and sill, and stand on a seat that's moulded into the monocoque. Try to slide gracefully into a sitting position. Replace steering wheel. Find a lever mounted low and to the right of your right knee, and use it to move the pedal box into a comfortable position. Wait for a nice bloke from KTM to strap you into your harness because you've already put your helmet on and can't see where the straps are. Place your feet on the clutch and brake pedals. With your right index finger press the rubberised start button on the transmission tunnel beside you. Wait expectantly for the engine to fire into life.

It doesn't. That's because you now have to press the 'mode' button nestling amongst a plethora of buttons on the steering wheel. Up springs the 'Are you ready to race?' message. A second stab of the starter button confirms that yes, I am indeed ready to race. Or perhaps not that ready because I stall in the pit lane and then have to press the 'stop' button before going through a big chunk of the process again...


At 790kg - and that's dry - the X-Bow R isn't the featheriest of track cars, but the 300bhp doesn't half make amends. In reality, it's the 295lb ft of turbocharged torque peaking at 3300rpm, that ensures the R rockets away from the end of the pitlane with unexpected and quite considerable vigour: from a standstill it'll hit 62mph in 3.9sec. With a helmet on the nuances of the engine note are lost to a hurricane of wind roar, so it takes a moment or so to realise that the insistent red blinking the right-hand side of your peripheral vision is a change-up light. It's a flashing beacon you see with great frequency, because the slick Audi motor is a rev whore, meaning your arm is bounding back and forth from the alloy gearlever at a pace almost brisk enough for the Chinese Olympic ping-pong team.

With each fresh ratio comes a fresh slap of thrust, and while the engine delivers the goods in a fairly linear surge, towards the top end - 5000rpm through to the flashing light at about 6200rpm - it really ups the ante. And when that happens on the approach to a corner, it makes you question the wisdom of keeping your toe down all the way to the braking point.


Adding to the sense of drama is the fact that the air flowing over the cockpit roils madly, batting your head from side to side and occasionally threatening to rip off your helmet. Spend time in the gym working out your neck muscles before considering a prolonged stint in the R, although it seems that a screen is being developed for launch next year.

The brakes are nicely set up. Powerful. Progressive. Give you the confidence to go deep towards the corner. They don't lock up even when you're hard on them from 130mph. Even on the slicks of this racer, the R turns in with a lightness of touch; there's huge grip but the steering wheel doesn't feel overburdened by the cornering force. If you're unaccustomed to slicks, it takes a few bends to work out that even if you've messed up your entry line, you can usually just steer the nose back to where it was meant to be and it won't wash wide.


The Spielberg Ring has a couple of long, fast sweepers and the racing R employs its aero package to hunker down and hurtle around them, plenty fast enough for you to start wondering if you could make it through all that gravel and reach the Armco if it all went awry. On a couple of laps there's a little twitch through the wheel, a need for a snippet of corrective lock, but it doesn't feel twitchy. A few laps later one of the pro drivers spins in front of me, however, and later still a couple of other journalists cruise back into the pit lane to have piles of stones and dust vacuumed from the undertray and footwells, so clearly the X-Bow will spit you off if properly provoked.

After the racer, it's time to try the press demo car. It's got the aero but not the slicks, 'making do' with Toyo grooved slick trackday rubber. First tight corner and the reduced level of grip becomes very apparent. Slight slide: not expecting it. Not the fault of the tyres, merely my inexperience.


But having less grip allows the strength of the engine to muscle through, because one of the few pieces of advice from our KTM hosts is to use a gear higher than think is right; being in a lower ratio out of a tight corner boots the tail out of line. Use fourth, say, rather than third, and you can steer your way through the bend without the corrupting influence of a power-startled tail, exiting with 3500rpm on the dial and a big slug of thrust booting you down the straight.

The third of my X-Bow R's doesn't have aero, yet does have the Toyo trackday tyres, but the fronts are narrower than the car I've just been in. Sure, this one isn't as stable in the sweepers, but its nose moves quicker making the whole car feel more nimble. The outright pace of the other two isn't there around a lap, yet it's more involving, more entertaining, less likely to intimidate drivers without an intimate knowledge of downforce and slick grip.


Last of my line, the standard car, and it too is as playful and able as the car I've just been out in, quick without being nerve-jangling - despite sliding earlier than the others - and connecting readily with the driver. It's a real joy to thunder around in and makes even a numbskull like me feel like a racing hero.

Oh yes, it's real easy to feel the love for the X-Bow R. Until it comes to paying. The basic car is approximately (depending on the prevailing Euro/Sterling exchange rate) £57,850. Plus VAT. Plus delivery (from Austria). Plus first registration costs. Then you're bound to want some options - the aero bits, for instance - and maybe some upgrades, of which KTM has plenty to offer. If you need a calculator to tot up that little lot, then you can't afford one... And if it weren't for that little stumbling block, I'd have one tomorrow.

Quite a trick car and certainly striking looks...but given that a Caterham R300 would be about half the price and probably just as much fun on track, better on the road and even a bit more practical I'd find it difficult to justify buying one.

I wouldn't say no to a KTM Duke or RC8 though!

Nice write up. I love these, fortunately the price is irrelevant as I couldn't justify one if it was 50% cheaper.

I think this car is hamstrung by the carbon tub. It dictates a high unit cost before you've even started with the other components and in this case does it even add anything above what a space frame provides. It's heavier than its competitors, no quicker, and offers no real handling benefits.

At that price it really needs a roof too. At least then if becomes a more palatable proposition and places it with cars of similar price - Chevron GR8 for example.

That said, I like them.

It's a 340R!

(only, assembled properly with an engine not as likely to turn into dust when you touch the throttle)

Most of the existing X-Bow owners had theirs modified with the factory 300Bhp upgrade, and the aero kits can be bought direct from KTM for a few grand each, so there is no incentive to move to the R when an existing Superlight can be turned into an R for 15k less than their (base) asking price.

Indeed - its what I swapped my 340r for - different league in terms of build quality and reliability smile

I have to agree! I mooched around one and the build quality for a toy is absolutely astounding! It'd shame Rolls Royce.

I'm not sure...if you're going to make the sacrifice and buy a track weapon go balls out and get a radical or a an Atom.

Out of interest, was that a boast by the manufacturer on the day?...

I love these but wish they would put a normally aspirated engine in one.

I also look forward to seeing the forthcoming screen as the head buffeting sounds a right pain.

The whole car oozes quality, if you get a chance have a look at all the bespoke parts in the front suspension alone! Mine's running 360BHP and to be fair could probably take 450! (not sure I could!) I've found the quickest way to drive it is on the torque. Change up early and feel the shove biggrin Braking's not as good as my old R400 but the car is a fair bit heavier. The old Caterham rule of "slow in fast out" doesn't apply, it's "fast in faster out here"! Handling on the road is, shall we say, exciting but predictable (to be fair mine is setup for track use). What would be great is a sequential box. Have receipts for about £85k to get mine to where it's at, they are expensive...!!!
Edited to add. Buffeting isn't that bad...

Right from the launch I've felt they need a version of this car which can be bought by normal humans for road use. The sooner the better because sales to date have been pitifully low.

I'd agree that the buffeting is over-stated. It's more the cornering forces that place the strain on your neck, not the lack of front screen.

Bad enough on 888's Just got sorted with a nice set of wheels and sticky slicks for mine. Maybe have to invest in the head support laugh

If it were 500kg I'd see the point, but less than half that kind of money buys you a supercharged Honda'ed Exige S1, which has the same power and weight, but manages a roof and space for bags, plus looks a darned sight better. Yes, I'm sure they're well built, and I guess with all that carbon they might be safer to have a big accident in, but it really just doesn't make sense to me. Glad they exist, though. :-)
