The extruded aluminium sills significantly increase 
the rigidity of the bodyshell. 
The much higher rigidity is achieved thanks to a 
modified inner geometry.
The result is best-in-class static torsional rigidity.

These impressive results are basically
attributable to three factors:

–   selective use of materials according to their 

function

–   the special bodyshell construction
–   Audi's cutting-edge expertise in the 

use of aluminium as a body material, and in 
particular the Audi Space Frame ASF

Rigidity has been further enhanced by extensive modifications to the sill architecture.

Convertible top design

Fabric convertible top with space-saving 
folding system

A special new feature of the new Audi TT Roadster 
is the Z-fold system of the fabric convertible top, as 
a result of which the convertible top takes up only a 
small amount of space when folded down. 
With this space-saving folding system, the front 
section of the roof lies on top of the cloth like a 
cover and locks into place to lie flush with the body.

The side openings for the drive motor of the 
convertible top mechanism are covered by 
convertible top flaps. As a result, there is no need 
for a tonneau. The linkage for both the fully 
automatic and manual convertible tops is made 
from a combination of steel and aluminium 
components and, as a result, is exceptionally light.

Acoustic and thermal insulation have been improved 
yet again by using insulating materials for the black 
inner headliner exclusive to the automatic 
convertible top. 
The convertible top linkage for the fully automatic 
convertible top is completely covered by the black 
inner headliner in the drive motor area. 
The rear window is heated and made of scratchproof 
mineral glass. It is larger than the predecessor's rear 
window and provides good all-round visibility when 
the convertible top is up. 
Thanks to excellent thermal insulation and the 
heated glass rear window, the new Audi TT Roadster 
is absolutely winter-proof.
