Fiat will build a fourth variant of its small 500 car called the 500L, or "L" for large.
The five-door, high-roof hatchback, known previously by its L-Zero codename, will be unveiled next month at the Geneva motor show.
The car's front end is similar to the 500 but the 500L variant sits on a widened version of Fiat's small vehicle platform used by the Punto hatchback. Expect the 500L to be around 4150mm long, about 60mm longer than the 500 hatchback.
Fiat will eventually offer two versions of the 500L: the five-seat standard model followed two months later by a seven-seat variant, which will be around 10mm longer than the five-seat model.
Sales of the 500L in Europe will begin in July. The Italian carmaker plans to offer the seven-seat variant in Europe only, while the five-seat model will also be exported to the United States beginning early next year. Fiat believes American customers won't buy a seven-seat vehicle as small as the 500L.
