Alfa Romeo concept sketch by Stile Bertone – Click above for high-res image

Two down, one to go. Well...not quite. Three of Italy's most venerable design houses are set to unveil concept cars at the upcoming Geneva Motor Show that will at once both celebrate Alfa Romeo's centenary (and, by extension, their historic collaborations with each of the studios) while bidding to replace the current 159/Brera/Spider range. Pininfarina's will be a roadster, Bertone's a coupe and ItalDesign's a sedan. PF has already released a sketch of its design, but if you thought that was a tease, Bertone's (pictured above) gives even less away.

Bertone has been in flux these past few years, caught in the middle of a legal battle between members of the family. Alfa Romeo's parent company, Fiat, recently acquired the old manufacturing facility, but left Stile Bertone independent. It's that design studio – headed until recently by one Jason Castriota and responsible for such designs as the Alfa 8C-based B.A.T. 11 and the Corvette ZR1-based Mantide – that will be bringing out the concept.

Other than the novel take on the classic Alfa grille shape, expanded outwards to accommodate LED headlamps, there's not much else to tell, but we can't wait to see what Italy's finest have to offer when we get to Geneva's Palexpo.
