A new Audi crossover has been revealed in a series of design sketches, showcasing a host of visual elements that will appear in future all-road and Q models.

The two-door show car will make its debut at January’s North American International Auto Show (NAIAS) in Detroit featuring a “Shooting Brake” body style and a wide confident stance.

First impressions are of a thinly-veiled Q1, which was confirmed by Audi CEO Rupert Stadler earlier this week. The entry-level Q model will be produced at Audi’s Ingolstadt plant from 2016 and is based on Audi’s modular transverse engine concept.

Another design sketch for the entry-level Q1 or a thinly-disguised look at the next generation TT? You decide.

Audi’s crossover measures 4.2 metres in length, sits on 19-inch wheels and features a striking side ‘tornado line’ to the taut, coupé-like rear.

Sound like anything else in Audi’s range? The current TT, due for replacement in 2014, measures 4.2 metres in length and features a high waistline, shallow glasshouse and prominently flared wheel arches, so perhaps we’re looking at an all-road, shooting-brake concept version of the next TT.

To quote Audi from their press information, “The new Audi show car is a compact sports car redefined”

Audi say it features “precise and clearly drawn lines as well as geometric surfaces [which] are combined to create a sculpted, clear design form.” The overhangs are short; the roof line is low and it ends in a strong C pillar.

You can also spot design elements from the e-tron models, such as the ribs in the Singleframe grille and in the side air inlets, while the dual headlights and the honeycomb-structured come from the design language shown on Audi’s Sport quattro concept.

Inside there’s a dash layout based on the latest A3, which we’ve already seen in the test mules of the next TT, so chances are that’s precisely what this is. It seems unlikely that Audi would produce the Q1 and a compact crossover of the same dimensions, but I’m sure we’ll find out in time.
