Well, this one will save us a lot of typing: Later this year, Subaru will officially remove the "Impreza" name from the WRX and STI. The thought process here is that focusing the Impreza line on fuel economy (30 mpg combined) and interior space (2 inches more leg room) is more important these days than associating the newly redesigned sedan with the high-performance WRX and STI versions.
On the other side of the equation, this will allow Subaru to add features and tailor marketing more appropriately for a car in this price range.
The division of Impreza and WRX/STI will grow in 2013 when the WRX/STI will split off from the Impreza platform onto one designed for the performance variants.
No details were given on the new WRX or STI, but Bill Cyphers, Senior VP of sales for Subaru of America said that the STI would have 300-plus horsepower.
