LONDON, England -- Red Bull Racing will switch from Ferrari to Renault engines next season, the Formula One team confirmed on Tuesday. At the same time, Red Bull-owned Toro Rosso will take over their sister team's Ferrari supply. Red Bull had announced a deal with champions Renault last month, in addition to the existing Ferrari contract, but had yet to confirm which of their teams would use which units. Ferrari said in a separate statement that the deal with Red Bull Racing, which had a year to run, had been terminated by mutual consent and a new two year contract agreed with Toro Rosso with an option for one further year. Italy-based Toro Rosso used Cosworth V10 units this year
