The 2 Series diesel would also compete with its own 3 Series diesel.
Good point about that Audi A3 TDI, at the moment it is a hatchback and probably not something someone interested in a 2 series would look at, since the bmw 2 series only comes as a coupe and sedan so far.
But as the new Audi A3 sedan becomes available, there's a good chance a version of the 2.0L inline four diesel engine can make it to the 2014 A3 sedan.
