The hide-and-seek continued in Barcelona on Thursday as F1 observers try to decipher the hierarchy for the start of the 2011 season.
Accused of sandbagging, Red Bull's Mark Webber told Autosprint: "We have no time for that. We already have enough to do."
The Australian also towed the line about it being impossible to rank the strength of the 2011 field, but at the same time mused that he thinks the Ferrari is the best car.
"I point to Red Bull," Ferrari's Felipe Massa shot back. "They won the titles last year but I hope Mark Webber is right."
Italian reports say Ferrari has never unveiled so many pre-season developments as have been seen on the 150 Italia car in Spain this week.
"No one knows today how scary Red Bull are going to be," said the Italian team's Spanish test driver Marc Gene on La Sexta television.
