The ongoing discussion about the engine regulations for the 2014 World Endurance Championship, and the national series which share those rules, has taken a new twist: the latest rumor is that both Formula One and WEC will use 1.6-liter turbocharged four-cylinder engines.
Mike Fuller at MulsanneCorner.com, a usually reliable source, first tweeted the rumor Tuesday morning.
No definite word yet on the fuel-consumption limits proposed earlier, nor about alternate fuels, energy recovery, or hybrid systems.
Earlier this year, engines as large as five liters were being discussed, along with fuel-flow instead of airflow restrictors to limit power, and also an overall energy limit per race: that is cars would be given a specific amount of energy the car could use in a race, whether that energy was generated from an electric mot, an internal combustion engine or a combination of the two.
With Porsche and Audi (part of VAG) considering entering both series in 2014, this might make sense. Audi’s influence on engine regulations kept its diesel engines at the top of the heap for several years.
