Ferrari is known for hyper-exotic supercars, speed and big price tags. There is a reason, though, that we didn't mention fuel efficiency. Hopped-up V8 and V12 engines don't exactly conjure up images of tree-hugging, and, for the most part, we're more than okay with that.

That could change, at least a little bit, with a patent that describes a hybrid powertrain that passes on flywheel technology in favor of a more mainstream effort. Car and Driver reports that the Italian supercar maker has filed patents for hybrid technology that would use a pair of electric motors and a battery pack.

The hybrid system would utilize one electric motor that assists the powertrain while the other runs auxiliary systems like air conditioning, infotainment and power steering. The patent also reportedly mentions that the technology would play nicely with a front-mounted 90-degree engine, making the California a likely destination if this system ever sees the light of day.

There has been some speculation that Ferrari might opt for a production version of its racing-derived Kinetic Energy Recover System (KERS) that captures energy via a flywheel to provide short bursts of energy. Ferrari's KERS uses a battery and has a single motor, with the accessories driven off the engine. Ferrari introduced a 599 concept in 2010 that included the fuel-saving tech.
