The lines of the A3 recall the silhouette of a coupé. The interior gives the impression of lightness, comfort and simplicity. The central part of the console opens upwards, creating a sort of ‘sail’ that divides the facia into three parts with very distinct shapes and colours. The car rests on a floorpan that was developed expressly by Pininfarina. All the components of the exterior and interior bodywork and the suspension were developed and engineered internally, and the company also carried out the mathematical modelling, the prototyping and the virtual validation.
Changes were made to the interior of the A3 sport to highlight its sporty character; they regarded the seats in particular, which are more sculpted, with highlighted overstitching, and the door panels, which have a more aggressive, more dynamic line. Pininfarina also performed all the engineering development of this car, producing a perfectly functioning prototype.
