The German luxury brand's new pint-sized all-wheel-drive hot-hatch is powered by a 2.0-litre turbocharged four-cylinder engine borrowed from the Volkswagen Group (namely the VW Golf GTI), with a power output of between 162kW and 188kW expected. Some are speculating a 0-100km/h time of around 6.5 seconds, though we would not be surprised if it could sprint a little quicker than that.
International reports suggest it could be sold with a six-speed manual gearbox only, though there are rumours of an optional S tronic seven-speed dual-clutch automatic.
The car boasts more aggressive styling at the front end, with a revised bumper seeing the addition of gaping mesh-lined air intakes, and new LED headlights with red highlights. The rear sees a new black strip on the boot-lid and a new rear wing, while quad exhausts poke out prominently beneath the rear air splitter. It also adopts Quattro badging on the bottom of the rear doors, and is expect to ride on 18-inch alloys as standard.
The new S1 Quattro ties in its bold exterior paint colour in the cockpit, with yellow stitching on most leather-lined sections of the interior, including the doors, seats, and gear shift boot. There's a body-coloured storage bin under the centre stack, a flat-bottomed S-line steering wheel and red-rimmed air vents. The only images seen so far show a five-door Sportback version, and there's currently no indication that a three-door model will be sold.
More details will be available closer to the car's debut, but Audi Australia will offer the new S1 by the end of 2014. Where it fits is the big question - the current A1 range tops out with the 1.4 TFSI Sport at $39,900. We'd expect there could be something of a range realignment when the S1 arrives, and it should be priced well below $50,000.
