X-Bow by KTM



In 2011 the product range of the super-sportscar with the carbon monocoque expanded to include the KTM X-BOW R, the most powerful version yet developed. The X-BOW “R” is the result of concentrated further development of the already spectacular lightweight sportscar.
In the rear of the “R” is a 300 bhp 2.0 Ltr TFSI engine from Audi with a maximum torque of 400Nm. This ensures an unbelievable driving experience both on and off the racing circuit, because naturally the KTM X-BOW R is homologated for use on the road.
At the German premium carmaker Audi, KTM chose one of the most efficient and powerful engines with a 2.0 Ltr displacement. This is all about an engine block that was used by the Ingolstadt-based company for a long time in the S3 model and which generated up to 265 bhp there. It was later also used in the Audi TT-S with 272 bhp. For use in the KTM X-BOW R, the reinforced block has a bigger turbo, an altered fuel injection system and the engine electonics have been additionally updated by Bosch Engineering Group.
This means that the performance not only increases to 300 bhp but also the torque: to be exact 400Nm is available from 3,300 rpm and results in a very smooth torque curve which provides impressive drive in all situations without the usual 'surge' that could upset lightweight sportscars.

This was how the KTM X-BOW evolved into the ‘R’ but it was far from complete. For the engineers, the additional power meant that the entire vehicle dynamic – from the engine mounts to the suspension had to be refined - and that is why, in addition to the engine, many other parts of the vehicle were either changed or completely redesigned.

60 bhp more is a good 25 percent increase. This of course creates far more extreme forces on the surrounding chassis and subframe which must be countered. It was the aim of the development not simply to meet the additional burden but to strengthen the rear far beyond that of the original 240 bhp model. The solution was to reposition the engine torque support arm. Up to date this had been attached to the rear frame, now it sits directly on the carbon monocoque. With this update, the torsional stiffness is significantly increased, especially when accelerating out of corners and the KTM X-BOW R handles even better on the road as its “little brothers” the X-BOW Street and Clubsport.

By relocating the torque arm and its connection, the developers then faced another demand. The entire engine unit should be lowered to further lower the centre of gravity. The drive unit now sits lower in the rear frame by a massive 19 mm. The net effect: the vehicle’s already impressively low centre of gravity has been moved even further down towards the road surface so that the central centre of gravity of the vehicle is lower by 15 mm. As a direct consequence even higher cornering speeds and greater lateral acceleration of more than 1.5 g is possible and the handling the KTM X-BOW R is improved.

So - with 25 percent more power, higher cornering speeds, greater G-loads. All this has resulted in significant additional burden on the chassis, which in combination with the tires represents the final link in a long chain for achieving optimal contact with the road. The push rod suspension on the front axle, which comes directly from the Formula racing sport, but also the suspension on the rear axle has therefore been revised.

The first step was trying to reduce the friction on the wishbone s of the X-BOW. For this purpose special Teflon washers have been used to reduce the friction and play, which at the same time improving the precision and the response of the suspension. In addition to this the engineers devoted time to the springs and shock absorbers: stiffer springs in the front and rear suspension and new damping characteristics meant that the KTM X-BOW R is characterised by notable handling improvements over its predecessors.

Alongside the X-BOW R a number of Motorsport derived Aerodynamic and Performance Packages have been created.  These allow the X-BOW R to be personalised for performance and appearance.



The X-BOW R features in detail:
- Carbon fibre racing monocoque with crash box in visible carbon fibre
- Audi 2.0 TFSI engine with direct fuel injection and 220 kW (300 hp)
- Mechanical limited slip differential
- Smooth surface racing underbody with a rear diffuser in aluminium composite
- Individually adjustable pedals
- Adjustable removable multi functional steering wheel
- Sports suspension, adjustable in rebound and compression damping
- Keyless go system
- Painted rims
- 4-point safety belt
- Special paint work in “R” Design

Factory-fitted special options are also available:
- Performance & Aerodynamic Packages
- and of course a wide selection of KTM PowerParts.
