The Idea was Fiat's first entry in the compact MPV market, sharing its platform with the second-generation Fiat Punto; exterior design by Fabrizio Giugiaro and interior design by Fiat's Centro Stilo. The Idea was conceived as a compact, mono volume MPV - i.e., to integrate the handling and compact size of a B-segment car under four meters in length with the increased height, flexible seating, cargo configurability and versatility of an MPV. The Idea debuted at the 2003 Geneva International Motor Show.

Under the direction of Giorgio Ascanelli, Maserati began development of an FIA GT-eligible race car. This car, which would eventually be named the MC12, was initially called the "MCC" ("Maserati Corse Competizione") and was to be developed simultaneously with a road-going version, called the "MCS" ("Maserati Corse Stradale"). Frank Stephenson, Director of Ferrari-Maserati Concept Design and Development at the time, did the majority of the body styling, but the initial shape was developed during wind tunnel testing from an idea presented by Giorgetto Giugiaro. The MC12 was developed to signal Maserati's return to racing after 37 years. 25 cars were produced.

The revision of the Fiat Palio Weekend is part of a second comprehensive revision of the Palio line. The update mainly concerns the engine aspect and the components that ensure safety. But in Europe, the new model featured a redesigned front fascia and interior with rear fascia similar to Palio 2001 version.

The restyling, always the work of Giugiaro, included extensive changes, partly due to changes in pedestrian safety regulations. The update involved the engines and the power supply, but also the body style, in lines and headlights.
