Fiat's Trepiuno (3+1 in Italian) concept will be the first look at the Italian automaker's 2007-2008 microcar.
Fiat invented the microcar in the 1950s with its 500 bubblecar.
Now minicars such as the Renault Twingo and the Smart ForTwo dominate the market.
The 3+1 is heavily inspired by the original Fiat 500 styling, both outside and inside.
The 3+1 name derives from its innovative seating system, developed in cooperation with Johnson Controls.
The 3+1 is a 4-seat car in its standard configuration but only the front passengers have a comfortable amount of legroom.
The front passenger seat moves upward thanks to a folding glove box. This offers a third passenger in the back the same legroom as the front-seat occupants.
The car can be transformed into a pure 3-seat or 2-seat vehicle by folding one or both rear seats.
The 3+1 is about 3300mm long. Fiat has not disclosed its wheelbase or possible engine specifications.
Turin-based design and engineering company I.de.A built the Fiat 3+1 concept car. The styling was created by Fiat brand's styling center.
Fiat is considering other minicar options.
It may also build a 2-seat model around 2500mm long similar to the Smart.
