MONTMELO, Spain -- Red Bull boss Christian Horner believes Mercedes and Ferrari are working together to shape Formula One's landscape in their favour.
The start of 2018 pre-season testing has reignited focus on the political battles expected to dominate this year, as F1 owners Liberty Media continue to negotiate with teams about the post-2021 engine regulations. Ferrari threatened to quit when the original proposal was tabled in the latter stages of 2017 and has recently floated the idea of creating a breakaway series. Mercedes was also apprehensive about Liberty's original blueprint.
Horner used his first official media appearance of the test to take a dig at the pair, who fought for last year's championship, referencing Mercedes' decision to broadcast Ferrari's Maranello launch shortly after its own at Silverstone last week.
