Do you think Honda and Chevy REALLY want to take on a team like DRR? Let alone a group like Dragon? They are tired of taking refugees for the sake of the series.
If you signed a deal with Lotus, deal with it. Nobody told you that the engines were all going to be the same, and you can't walk into Renault with a check and demand an F1 supply, nor can you walk into Hendrick's shop and demand Hendrick Cup Chevys for the year. Welcome to racing.
