Here's my proposal for a coupé version of Audi's S3. But I haven't just lopped off two of the doors and called it a day - my S3 Coupé has taken design cues from Audis past and present to give it a completely new look to the regular four-door car.
The fastback roof is a modern take on that of the 1960s Audi 100 Coupé. The upswept rear quarter windows are also a nod to that car. An Audi A1-style roof contrast line (shown here in brushed aluminium) traces the sporty roofline.
The pictured car showcases many optional extras including: the Audi logo decals on the doors (a reference to the urQuattro), the black pinstripe connecting the front of the car to the rear, and the piano black finish between the rear lights.
