According to a recent report, the upcoming Audi S1 will be based on the A1 Quattro but feature a detuned 2.0-liter four-cylinder petrol engine with 185 PS (136 kW / 182 hp) to 256 PS (188 kW / 252 hp).

We haven't heard much about the Audi S1, but a recent report says the car could be coming in the second half of 2013. 

What Car says the model will likely be based on the A1 Quattro, but feature a detuned 2.0-liter four-cylinder petrol engine. This means we can expect an output that slots the car between the 185 PS (136 kW / 182 hp) A1 1.4 TFSI and the 256 PS (188 kW / 252 hp) A1 Quattro.

There's also word of an RS1, but a spokesperson said the model hasn't been green-lighted as of yet.
