Red Bull will use Honda engines next season in a switch that marks the final severing of a once-dominant Formula One partnership with Renault that turned sour.
"After careful consideration and evaluation we are certain this partnership with Honda is the right direction for the team," Red Bull Racing principal Christian Horner said in a statement announcing the deal for 2019 and 2020. Red Bull won four drivers' and constructors' championships in a row with Sebastian Vettel, now at Ferrari, and Renault between 2010 and 2013. The pairing also won 47 races before the current V6 turbo hybrid power units were introduced but Renault's struggles with the new format stretched the relationship to breaking point and the British-based team now brand their engines Tag Heuer. Honda also had their difficulties, switching to Red Bull's junior team Toro Rosso this season after a failed three-year partnership with McLaren ended in mutual recrimination.
McLaren now use Renault power units, but their car has still under-performed Red Bull. Red Bull's decision to switch to the Japanese manufacturer means their two teams now have exclusive use of Honda engines but could complicate efforts to retain Australian Daniel Ricciardo. Ricciardo, 28, has won twice this season but is out of contract at the end of 2018 while 20-year-old Dutch team mate Max Verstappen has a long-term deal. Horner hoped Honda could take Red Bull back to the top. Honda president Takahiro Hachigo said the deal would give the manufacturer access to twice as much data. Renault acknowledged the decision in a statement as "a natural evolution" for both parties.
