(from KTM Press
Release) The KTM X-BOW R celebrates its debut
FIRST EXCURSION TO THE RED BULL
RING!
So now the new KTM X-BOW
R is here. The completely revised, even more powerful super sports
car from Austria has been presented to the public in the series
version. Just two days after the official opening of the Red Bull
Ring in the presence of national and international motorsports
personalities, the “R” has been able to show just what it can do on
this racing circuit. True to the KTM “Ready to Race” motto the “R”
model was driven on the road straight from the assembly line in Graz
directly onto the racing circuit.
And even if the new developments of the KTM X-BOW R are not obvious
at first glance from its outward appearance, a lot of things have
been changed around the carbon monocoque. The engineers did not
restrict themselves to improvements to the engine. In fact there
have been improvements in all other relevant components to ensure
that an optimal performance can be achieved. And that is because the
customers had clearly expressed their wishes that the super sports
car that many of them want to take to the racing circuit weekend
after weekend, should be even more extreme, even faster and even
more powerful.
And what the customer wants is what KTM delivers. In 2011 the
product range of the super sports car with the carbon monocoque
includes the KTM X-BOW R, the most powerful version yet developed.
The “R” is the result of concentrated further development of this
spectacular lightweight sports car. In the rear of the "R" is a 300
h.p 2.0 Liter TFSI engine from Audi with a maximum torque of 400 Nm
and 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 litre 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 h.p. there. It was later also used in the TT-S with 272 h.p. For
use in the KTM X-BOW R, the reinforced block has a bigger turbo, an
altered fuel injection system and the engine electronics have been
additionally updated by Bosch Engineering Group (BEG). This means
that the performance not only increases to 300 h.p but also the
torque: to be exact 400 Nm are set free at 3,300 revs and results in
a very smooth torque curve which provides impressive drive in all
situations.
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 periphery – from the engine mounting to the suspension had to
be reviewed. And that is why, in addition to the engine, very many
other parts of the vehicle were either changed or completely newly
constructed.
The stay of the torque support arm
has been completely changed
60 h.p more – a good 25
percent – caused far more extreme forces that meet and must be
absorbed on the engine mounting points on the aluminium rear frame.
It was the aim of the development not simply to meet the additional
burden but to strengthen the rear beyond that of the 240 h.p model.
The solution was to reposition the torque support arm. Up to date
this had been attached to the rear frame, now it sits directly on
the carbon monocoque. With this, 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.
The entire drive train unit has
been lowered by 19 millimeters
By relocating the torque
arm and its connection, the developers then faced another demand.
The entire engine unit should be lowered to lower also the center of
gravity. The initial target could be even exceeded thanks to clever
construction so that the drive unit now sits lower in the rear frame
by a massive 19 mm. The main effect: the vehicle’s already
impressively low center of gravity has been moved even further down
towards the road surface so that the central center 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 of the KTM X-BOW R is significantly
improved.
The suspension has been
significantly revised
25 percent more power,
higher cornering speeds, greater G-loads. All this has resulted in a
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 been revised. The first
step was trying to reduce the friction on the wishbones 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 characterized by an
additional increase in the handling, even more extremely exact and
delicate than up to this stage of the development.
The price of the KTM X-BOW R is € 58, 795 (excluding national taxes
and import duties).
