Thee next-gen Alfa Romeo 159 concepts will be built by the Turin design houses for a Geneva introduction. Details inside.

Alfa Romeo will introduce three different variants of the 159 at the Geneva Auto Show in March, according to Inside Line. The three concepts will demonstrate different directions the company could take with the next-generation model, while honoring the firm's 100-year anniversary.

A company source told Inside Line, "At Geneva, each of the Turin design houses - Stile Bertone, Pininfarina and Italdesign Giugiaro - will create a version of the new midsize model to be shown at their respective stands." The blog notes that Bertone will likely build a two-door coupe, Italdesign Giugiaro could create the four-door sedan, and Pininfarina will make the drop-top.

The 159 replacement will also likely get a name change, taking on one of the company's historically used names. This could become a trend with the company, which is using the "Giulietta" moniker of the 1950s and '60s for its next 157. That car will also be introduced in Geneva, with sales beginning by 2011.

The next version of the 169 is also due in the near future.
