Audi is set to revise its plans for the S1, according to sources close to the brand. It is believed that the S1 was to be front-wheel drive with up to 180hp, similar to the MINI Cooper S, but insiders say that this is not enough for Audi bosses who have decided against badging a front-wheel drive car with the 'S' moniker. Expect to see a four-wheel drive version with over 200hp in the future bearing the name.
