How can a team with no engines compete in F1 until 2020? Please, explain that one to me.
RB have been offered engines, but have elected not to take them as not being good enough. If they want to be in F1 (and they have to be based on their contract with Bernie), it might be interesting to see how they could get out based on "not having an engine" when they've elected to not accept engines from Renault, Ferrari and Mercedes because RB wouldn't accept what they were offered.
Sure, they might not be competitive with last year's Ferrari/Mercedes/Renault engine, but I don't see where RB can bail out of F1 because they are not competitive until they sort out a better engine.
It's like if RB sacked their drivers and then said they wanted out of their contract because they had no drivers and therefore couldn't race. Are we seeing McLaren threatening to quit because they don't have a Mercedes engine and their current Honda engine won't be competitive for another year or two (or more)?
It's all posturing by RB, and at some point they will have to accept what they can get or leave the sport and pay the penalties. RB have burned so many bridges, they've painted themselves into a corner, and yet no one want to give them a leg up that helps them beat a factory team - why would they?
It was only a couple of years ago that RB were winning championships with some questionable tech, and the constant reply from Horner was "the rules are the same for everyone". Rules that RB helped develop, agree to, and signed up for.
