Over the years we’ve loved many different versions of the Alfa Romeo 159 and with 100 years for the moniker arriving, Fiat promises a special treat at the Geneva Motor Show. This one is a teaser sketch of the Stile Bertone’s version of the Alfa Romeo 159 which will expectedly be a two-door coupe. Other than this, famous Fiat design houses Pininfarina and Italdesign Giugiaro will also ready their design proposals for the event, which will surely please the Alfa Romeo admirers. While Bertone’s two –door coupe design will be launched to celebrate the centenary celebrations in 2012, the other two design firms will also contribute equally with Pininfarina already working on a two-seater spider. The spider will feature a 444hp producing V8 beast from the 8C Competizione. Bertone will sure reveal more teasers before the event to keep the fanatics interested.
