Fiat Group brands Alfa Romeo, Fiat, Fiat Commercial Vehicles and Lancia will launch 20 redesigned models in the next four years, plus five new models that will take it into completely new markets, as well as face-lifting a further 23 models.

The new lines range from a tiny new Fiat city car, the 500, to a new Alfa Romeo model to sit above the existing large 166 sedan,  and new commercial vehicles.

Announcing the plans, Fiat CEO Sergio Marchionne said that the new models represent a continuation of the aggressive renewal of the Fiat Group's product range that began two years ago and which represent an investment of €10 billion, including €4 billion for research and development.

He hopes the new models will secure the long term future and success of the struggling Fiat Group.

Fiat has already launched the new Croma MPV (minivan) and announced the redesigned Punto Grande this year, but yet to come are the first details of a new 4WD model and more versions of the Doblo small van/MPV. These will be followed by four new models, including new mid-size hatchbacks and MPVs.

The Alfa Romeo 159 and Brera were launched this year and will be followed by the 159 Sportwagon and Brera Spider with two more new models and four major facelifts to follow in the next three years.

The Fiat Ducato large van will be joined by new models and versions that will expand Fiat's commercial vehicle range both upwards and downwards, as well providing a wider choice in the middle of the market. A new joint venture vehicle, called the MiniCargo, will take Fiat into a new market sector, while all-new replacements for the Ducato and its sibling, the Scudo, and a number of car and MPV-derived commercial vehicles are also planned.

Lancia - which, unlike Fiat and Alfa, now makes only left-hand drive models for sale in Europe - will launch three all-new models, included a 4WD, a medium-size luxury family hatchback billed as a successor to the legendary Delta and a vehicle described only as a "specialty" model.
