Ferrari are ramping up the pressure on Formula One authorities to change the sport's rules, saying a company survey shows most fans are unhappy with the new direction of the sport.

Ferrari released the findings on Thursday, ahead of this weekend's Bahrain Grand Prix, where their cars are expected to again be off the pace shown by front-running Mercedes.

The release of the survey follows a meeting between Ferrari chairman Luca di Montezemolo and F1's commercial powerbroker, Bernie Ecclestone. The pair are expected to meet with FIA president Jean Todt in Bahrain this weekend to press for changes.

While it may prove too difficult to change the new rules limiting fuel consumption, a possible short-term measure could be a reduction in race distances.
