Senner Tuning press release :
RS Bodywork for the Audi A5 Cabrio – by Senner Tuning INC
The German tuner Senner Tuning Inc., known for its extravagant
modifications, has now placed the golden crown on the Audi A5 Cabriolet.
The Audi tuner Senner Tuning Inc. is offering an extensive
individualisation program for the current Audi A5/S5 Cabriolet. The
Senner Tuning Inc. has fired up the new, blazing A5 2.0 T-FSI Cabriolet
even more. The performance of the turbo petrol engines has been
increased to 275 HP and 430 Nm with the use of sports air filters and
software optimisation. In addition, thanks to the Power Convertor
(responsible for the acceleration of the electronic gas signal) the gas
intake has an even quicker reaction time.
The tuner from Ingelheim offers an audibly superior exhaust system for
the A5, guaranteed to give you goosebumps. It is an in-house sports
exhaust system with a stainless steel finishing with four end pipes,
88x74mm in diameter. With this, the Audi gives the driver a real sports
car feeling.
The carbon hydride screw thread (Version 2, Inox Line) with adjustable settings ensures perfect road position.
For the wheels, only the best was good enough. On the right are Varianza
TIS light metal rims and on the left, Scwhert (“Sword”) SC1 light metal
rims in silver chrome with anodised lips 9×20 inches and 10.5×20 inches
in size with 245/30 R20 und 295/25 R20er Vredestein tyres – they cause
quite a sensation. You don’t need to trim the wheel arch edges for that!
In addition to the work on the open heart and wheels, the Ingelheim team
has also cosmetically improved the bodywork of the A5. The new spoiler
in the RS6 Design as well as the cooler grill are examples of this,
which includes exterior mirrors in the RS5 Design and a rear valance
with sporty diffusor fins.
Prestige in the interior is taken care of with surfaces made from
leather and extensive carbon fibre applications. The carbon set at
Senner Tuning Inc. includes a tacho blend, the S-Line sports steering
wheel, an ash tray cover as well as a further extension of door
applications, not exactly made with cheap material.
The whole thing is completed with the convertible roof module by Senner
Tuning Inc., which can be open and closed via radio signals.
Vehicle basic price incl. special tuning: 55.000 Euro
Senner Tunig Inc. Special modifications: 19.900 Euro
