At the end of the season, after the Abu Dhabi Grand Prix, it was announced that Toro Rosso would be reviving their partnership with Ferrari for the 2016 season, The only difference this time was that Toro Rosso would be provided with 2015 power units, as opposed to up-to-date 2016 power units used in previous seasons but without any direct factory support from Ferrari despite the partnership. Toro Rosso used Ferrari engines from 2007 through 2013 during the V8 normally-aspirated era. On 4 January 2016 it was announced that Toro Rosso would adopt a longer wheelbase for the all-new STR11 car due to the Ferrari 060 power unit and gearbox requiring a spacer to accommodate the MGU-K at the rear of the engine (similar to the Marussia MR03 which had a longer wheelbase: about 3,700 mm). After a controversial crash in Russia, Kvyat was brought back to Toro Rosso from Red Bull, with Max Verstappen taking his place.
