Just six months after Fédération Internationale de l'Automobile (FIA) president Jean Todt insisted that the plan for Formula 1 to adopt 1.6-liter, turbocharged four-cylinder engines by the 2013 season stood, motorsport's governing body has backtracked on its stance. Instead, F1 teams will be using 1.6-liter, turbocharged V6 engines from the 2014 season onwards.
The change comes after the FIA's World Motorsports Council consulted with Formula 1's stakeholders and engine manufacturers, which led to the adoption of the V6 turbo engines.
According to the FIA, the one year-delay on the introduction of the new engines came at the request of the four engine manufacturers currently involved in F1, not only to deal with the change in the engine's architecture but also to ensure that their projects are more robust.
To ensure that the engines will still be fuel-efficient despite having two more cylinders than what was originally planned, a fuel flow limit will be enforced through a technical regulation.
"The clear need for the automotive industry to reduce emissions means energy management will increasingly become a key factor in the development of more efficient power trains," the World Motorsports Council said in a statement. "Kinetic energy recovery is already applied in Formula 1 and the introduction of exhaust energy recovery will add another technology route to be explored. Formula 1 will also return to its role as a developer of turbocharger technology. This research will have real-world benefits, contributing valuable knowledge that will be of use to future road car development."
