Renault say Red Bull haven't approached them for supply past 2019

Renault has criticised Red Bull as their customer team have shown they will “never be able to appreciate the need for loyalty and commitment.” Red Bull are actively shopping elsewhere for power unit supply for 2019 and beyond.

Renault boss Cyril Abiteboul told the Daily Express that Red Bull's treatment of Renault over the years has led to a poor relationship between both parties.

Renault powered Red Bull to four consecutive world championships but saw little to no praise for the feat but have been blamed for their recent struggles since.
