Hi, in order to discuss the topic maybe without polemics, here is a survey. Multiple answers are not possible Make unit motors sense? Toyota and also Ferrari have categorically opposed it. Are they right or not? Should each team build its own engines? I remember the time of Cosworth when almost the whole field was driving with this engine Should the engineers be allowed to let off steam? The technology should be in focus here. If any of you want a survey to be made here, please contact the moderator team and we will be happy to post a survey on a given topic.
