Sauber Formula 1 chief Monisha Kaltenborn has confirmed that the Swiss team will race with year-old Ferrari power units in 2017.
Sauber has struggled financially in recent years, but had its long-term future secured over the summer when Longbow Finance took over the operation.
Speaking to reporters in Japan on Friday, Kaltenborn revealed that Sauber had elected to stick with the 2016-spec power units for next season a while back so that it could focus its efforts on other areas.
“We will be using the latest specification of the 2016 Ferrari engine in 2017,” Kaltenborn is quoted as saying by Reuters.
“We took this decision a while ago at a time where actually the rules for next year were not 100 percent clear.
“We took a strategic decision that we want to focus the resources we have on chassis development and performance development, and in a way leave the engine side to the areas we know.”
Besides its own works operation, Ferrari currently supplies Haas, Sauber and Toro Rosso with power units in F1.
As of 2016, Toro Rosso will return to a supply from Renault, having used year-old Ferrari units this year that has cost the team significant ground as the season has progressed and others have developed their engines.
With Sauber opting for year-old units next year, Haas will be the only team besides Ferrari to use 2017 power units developed by the Italian marque.
