may adapt its 2014 turbocharged 1.6-liter V6 engine for Formula 1 for a Le Mans LMP1 prototype - possibly as soon as 2015. 

The 2014 LMP1 rules do not put any limit on engine layout or displacement, but factory-backed cars must be partially electric powered. By adding the regenerative braking and generator that gets power from the engine's heat, it could go racing in the World Endurance Championship. 

The team has the option of either doing a full factory effort with a chassis and engine or following HondaHondaJapan, 1948 > present102 models

Finally, the new rules make the WEC a far more open form of motorsport. Anyone who casually watches Formula 1 knows that the rules keep the teams from truly pushing technology. It is not hard to argue that F1 cars were more advanced 20 years ago with active suspension and adjustments being made from the pitlane.
