The Audi A1 supermini will go on sale in March 2010, a secret company document has revealed.
The engineering papers, which were sensationally leaked out of Ingolstadt, detail the Audi A1's new line-up of four-cylinder launch engines.
The petrol model range begins with an 86bhp, 1.2-litre petrol engine. Further up there'll be a naturally aspirated 1.4-litre petrol with 122bhp and a high-performance, turbocharged version of the same unit that will yield 170bhp.
New diesel engines include a 1.6-litre common rail injection with 90bhp or a range-topping 2.0-litre common rail unit.
Audi is making no comment about the leaked document, but sources say an internal investigation has been launched.
