GM’s Saturn has doubled its 2007 lineup from three new models to six with the unveiling of its all-new 2007 AURA, SKY Red Line and OUTLOOK during the New York Auto Show. The AURA is a midsize sedan that designers say features a new design with detailed lighting elements. Officials say they are further enhancing the AURA’s fuel efficiency by offering a hybrid model later in 2007. The SKY Red Line is a roadster convertible that offers StabiliTrak control – a system designed to keep vehicles stable on all road surfaces by applying force to the appropriate brakes. Compared to the Red Line, the OUTLOOK offers ample room for eight-passengers and engineers say it is fuel efficient and emits low emissions.
