Speaking with the UK’s Auto Express, an Audi insider reportedly confirmed the future unveiling, before the S1 goes on sale to UK customers in May this year.
The 2.0 litre power plant is believed to produce around 172kW for the S1; 34kW less than the 206kW figure for the same engine fitted to the S3 in Australia.
Transmission choices are believed to include a six-speed manual and a dual-clutch S-tronic automatic with six or more ratios, and Quattro all-wheel-drive will be standard.
Exterior styling will reportedly be of a somewhat conservative nature, with upgrades over the standard A1 including larger air intakes in the front bumper, a more pronounced body kit and the addition of S1 badges.
The S1 is expected to be available in both three- and five-door body styles, with unique paint finishes and a quad exhaust system setting it apart from the A1.
A second source reportedly said that pricing would be similar to the Volkswagen Golf GTI, starting from around £27,000 (AU$51,251) in the UK.
That could mean a starting price of around $42,000 to match the GTI if and when a future Audi S1 arrives in Australian showrooms, but there’s no word yet from Audi on that front.
The Geneva Motor Show runs from March 6-16.
