KTM X-BOW R: SUPER SPORTS CAR TECHNOLOGY FOR THE 21ST CENTURY
MONOCOQUE
BELTS
Driver and passenger are protected by a four-point (also six-point upon request) safety belt from Schroth, which is also used in racing.
CRASH BOX
The crash box at the nose of the vehicle provides additional safety. Thanks to its carbon-aluminium sandwich construction, it even complies with the strict safety regulations of the FIA-GT and Formula 3.
TECHNOLOGICAL LEADERSHIP
The KTM X-BOW is the first production vehicle to boast a monocoque made completely from composite carbon fibre material – a trailblazing and pioneering technology, previously reserved exclusively for racing vehicles.
EXTREMELY LIGHT, EXTREMELY STABLE
Four layers of carbon fibre, epoxy resin, elaborate handiwork, autoclave technology: they all come together to produce the twin-wall, two-part, extremely lightweight, carbon monocoque, which is manufactured by composite-fibre specialist Wethje in Germany. The result is a carbon-fibre construction that provides the highest levels of safety, but only weighs 80 kilogrammes – with an unbelievably high torsional stiffness of 35,000 Nm/o.
ROLL BARS
In the event of a rollover, optimum protection is guaranteed by the aluminium roll bars integrated in the monocoque. They withstand loads of up to 2.5 times the weight of the vehicle.
DRIVE TRAIN
TRANSMISSION
Tried and tested in series production, but tuned optimally to the KTM X-BOW R: The manual 6-speed gearbox from Audi always has the right gear available – furthermore, it is equipped with an additional short-shifting movement. The Drexler limited slip differential that comes as standard guarantees optimum propulsion in every curve.
TORQUE CURVE
The engine achieves its maximum torque of 400 Nm at a speed of only 3,300 rpm – thereby making, in the truest sense of the phrase, "very light work" of the KTM X-BOW R, which tips the scales at a mere 790 kg. The maximum power output of 300 hp is attained at 6,300 rpm.
AUDI ENGINE TECHNOLOGY
The rear end of the KTM X-BOW R accommodates a 300 hp, 2.0-litre TFSI engine from premium manufacturer Audi. The state-of-the-art power unit works with gasoline direct injection and combines the dynamics of turbocharging with highly effective charge air cooling. Alongside outstanding power and torque characteristics, the four-cylinder engine surprises above all with its minimal fuel consumption: only 8.3 litres per 100 km in the MVEG cycle!
FRAME
The aluminium spaceframe is the central supporting element for the engine/gearbox assembly. It has been possible to lower the whole unit by 19 millimetres, thereby lowering the KTM X-BOW R's already impressively low centre of gravity by another 15 millimetres. As a direct consequence, even greater lateral acceleration forces and even higher cornering speeds are possible.
TORQUE SUPPORT
The extreme forces of the engine are cushioned in the KTM X-BOW R by a torque support, which is mounted directly on the carbon monocoque.
CHASSIS
PUSHROD SUSPENSION
On the front axle, the pushrod chassis - derived directly from the world of formula racing - features compression damping with high and low-speed settings as well as adjustable rebound damping. Such a suspension system is only used very rarely on production vehicles, since it is expensive and complicated – although the ride is incomparable.
BRAKES FROM BREMBO
Extreme power demands an equivalent level of brake performance. The KTM X-BOW R employs a Brembo brake system, featuring a four-piston, fixed-calliper brake on the front axle, with an internally ventilated, slotted disc measuring 305 mm in diameter; the rear unit is a two-piston, fixed-calliper brake with a diameter of 262 mm.
SPRINGS AND DAMPERS FROM WP
Together with chassis and test-drive guru Loris Bicocchi, WP Suspension was involved in developing the springs and dampers for the KTM X-BOW from the very beginning. This expertise and the accumulated experience with the set-up of the X-BOW are perceptible in the "R" from the very first moment.
MICHELIN PILOT SUPERSPORT
A high-performance tyre, developed especially for super sports cars and the ultra- high-performance segment, including the KTM X-BOW R: It offers safety even in the most extreme conditions and, above all, excellent handling in both the dry and the wet.
AERODYNAMICS
DOWNFORCE
The KTM X-BOW R supplies technical solutions from the racing world. The design of the ingenious aerodynamics - developed by KTM Technologies in cooperation with Dallara - is particularly impressive. Almost 200 kg of downforce are generated at 200 km/h thanks to the front splitter, underbody and rear diffuser. Depending on the tyres, up to 2.0 G of lateral acceleration is possible – more than with any other street-legal production vehicle.
DIFFUSER
Air flows optimally into the rear diffuser, which ensures distribution of pressure in the underbody thanks to its asymmetric design. It generates a large part of the downforce.
UNDERBODY
One look underneath the KTM X-BOW R reveals the three-piece, completely flat, racing underbody derived from formula racing vehicles.
Revolutionary. Puristic. Radical. In the form of the production version of the X-BOW, Austrian manufacturer KTM presented its interpretation of a super sports car for the 21st century in 2008. "We wanted to take Colin Chapman's idea of a spartan, lightweight sports car reduced to the bare essentials and transfer it into the new millennium – with as many technological innovations as possible," says KTM CEO Stefan Pierer.
Together with the specialists at Italian sports car manufacturer Dallara, the composites experts Wethje, the think-tank KTM Technologies and engine partner Audi, what is probably the most exciting super sports car of our times was produced in only 18 months. The extraordinary styling came from Gerald Kiska and the team at Kiska Design, who created an iconic modern sports car.
"Ready to Race" – this not only applies to KTM motorcycles, but also to the X-BOW. When developing the "R", we focussed on improving both performance data and overall performance. Even more extreme, even faster and even more impressive. The result is quite outstanding. The KTM X-BOW R has been designed down to the very last detail as an uncompromising driving machine. Many of the conventional elements aimed purely at comfort have been omitted. Dispensing with a roof and the windscreen as well as the omission of air-conditioning and entertainment systems all takes a little getting used to. But it allows concentration on the most important aspect: the driving experience!
