Ferrari are making contingency plans in case their KERS (Kinetic Energy Recovery System) is not ready for the start of the season.
The Italian team are still playing catch up with their development of KERS, but are determined to try and get it on the car for the start of the season.
However, they are not willing to take risks in case they face fresh hurdles before Melbourne - so are preparing themselves in case they need to race without it.
Ferrari's technical director Aldo Costa told Gazzetta dello Sport: "The objective is to arrive at the first race with a functioning and competitive KERS, but we also have a B plan: not a different car but a version without KERS."
Engine chief Gilles Simon added: "We are late with the KERS. We prepared a hybrid F1 car to test it, but the system isn't ready. In February we'll understand how to go to the first grand prix."
