SEPANG, Malaysia - The tension between Red Bull's Christian Horner and Renault's Cyril Abiteboul are palpable as the warring Formula 1 partners appear headed for divorce.
Horner said Frenchman Abiteboul, who earlier accused Adrian Newey of telling lies, was "brave" to be seated right alongside him in the official International Automobile Federation media conference during the 2015 Qatar F1 weekend.
Franz Tost, boss of Red Bull's second team Toro Rosso, confirmed media reports that the team was in discussions about being acquired by Renault.
