DETROIT, Michigan - The US-based Haas F1 team that plans to make its Formula 1 debut in 2016 will use Ferrari power units and gearboxes in a technical partnership announced by both sides on Wednesday (September 3).Haas F1, being set up by Nascar team owner Gene Haas, had already established ties with Ferrari and announced in July that it would sponsor the sport's most glamorous and successful team until the end of the 2015 season.EVOLVING PARTNERSHIPFerrari team principal Marco Mattiacci said: "A few months ago we joined forces with Gene Haas on a commercial level and this is the natural next step of our growing relationship."While our objective is to reinforce our power unit development programme for all our customer teams, we believe this new partnership has the potential to evolve beyond the traditional role of supplying our power units and all related technical services."The US continues to be one of the most important markets for Ferrari and it offers many interesting opportunities."Ferrari currently supplies three teams with power units - its own, Sauber and Marussia. Haa will be the first US-based team in F1 since 1986.Gene Haas is co-owner of the Stewart-Haas team that won the 2011 Nascar Sprint Cup Series championship.Stay with Wheels24 for the 2014 Italian GP this weekend.
