I dont speak japanese but from the looks of that article it says something about 300 ps and 400 ps. PS as in German horsepower...implying that we may see a few versions perhaps?
Oh and for all you thinking that this isnt what the 2012 3 could look like, how would you know? Auto manufactures usually have ideas and renderings of new vehicles 20 years in advance and have vehicle-on-wheel prototypes in 5. So this is a very likely candidate of the new 3 IMO.
