It's the ultimate A1 – and these are the best pictures yet of the hot hatch that will take the fight to MINI's John Cooper Works and the upcoming VW Polo R.
This is the new Audi S1, which our spies have caught undergoing testing at the Nurburgring circuit in Germany. Although painted a subtle shade of dark blue, it's obviously no ordinary small Audi – just check out the wider tracks, wider rubber, lowered suspension and twin rear exhaust pipes.
Likely to make its debut at the Frankfurt Motor Show later this year, the S1 is expected to pack quattro four-wheel drive and a 220bhp 1.6-litre turbocharged petrol engine. That would make it the only all-wheel drive car in its class and the most powerful too.
With 220bhp on from a new 1.6-litre unit – the same engine will be used in the Polo R – the S1 should be able to do 0-60mph in just six seconds with a top speed of around 140mph. A six-speed manual gearbox or an optional six-speed automatic (which the A1 quattro will also use) are thought to be the transmission choices.
There's no word on price but expect the S1 to kick off at around £23,000.
