|
| 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.
