AUBURN HILLS, Michigan, May 21 (Reuters) - Stellantis set out a new 60 billion ‌euro ($70 billion) business plan on Thursday that ‌includes 60 new car models by 2030 - from combustion ​engine to fully electric vehicles - new investments in technology, joint ventures with other carmakers and better use of its manufacturing capacity.

The Franco-Italian carmaker ‌said it ⁠would also refocus its sprawling 14-brand portfolio, with 70% of brand and ⁠product investments going to Jeep, Ram, Peugeot and Fiat, as well as commercial vehicle unit ​Pro One ​due.

CEO Antonio Filosa's ​pitch later on Thursday ‌to investors at the group's capital markets day on Auburn Hills, Michigan, is a major shift in the carmaker's strategy.

The world's No. 4 automaker seeks to turn its structural ‌disadvantage of having far too ​much unused factory capacity ​into a revenue-generating ​contract manufacturing business for Chinese automakers ‌in Europe and other ​carmakers like ​Tata Motors unit JLR in the United States.
