Ground effect and turbos to return for 2013 with new regulations?

Formula 1 teams are closing in on finalising the regulations for the sport from 2013 onwards, which is understood to include the reintroduction of turbochargers and ground effect. This is being done for two reasons: To improve the spectacle for the fans, and also to make the sport more environmentally friendly.

The most interesting changes being suggested, and nearly definitely being introduced, involve the complete reshuffle of the engines of the cars. The engines will be 1.6 Litre 4-cylinder models, and boosted by turbochargers. These new power plants should produce 650bhp, and should be powered by numerous energy recovery systems. While this last section cannot be fully explained, I would guess that it would involve the revival of KERS, as well as generating energy from exhaust gases.

Also added onto the engine regulations is a plan to limit each driver to 5 engines a season. On the environmental side of the engines, there will probably be a fuel flow limit introduced, which will limit and reduce the amount of fuel entering the engine. This will make the engines more fuel efficient, as Sam Michael, Williams technical director, explains:

"Rather than dump as much fuel in as we can at the moment, there 
will be a fuel flow metre - so you won't be able to blow more 
than a certain amount of fuel. It is a good chunk less than we 
had at the moment."

As for the cars themselves, Patrick Head, co-owner of Williams, and Rory Byrne, a former designer for Ferrari, are working with the FIA to write up new rules. On the safety front, the cars are being planned to have greater crash protection at the front, with the sidepods being moved forwards being the main objective.

Also, all of the teams are collaborating on changing the aerodynamic setup of the cars to improve overtaking opportunities, and ground effect is the main suggestion in this area. Put simply, ground effect reduces the pressure under the car, meaning that the area above the car will have higher pressure, therefore pushing the car onto the ground. This produces a huge amount of downforce when it is used correctly, and also does not turbulate the air as much as rear wings, meaning the car behind has a better chance of following the car in front.

While it cannot be 100% guaranteed that these changes will be implemented, I would still say that it is very likely. Personally, these all look like great changes, especially the ground effect, as the aerodynamic flow of air to a car running behind should be much cleaner, and could well be a good idea to improve overtaking without making it too easy (ie. proximity wings).

Also, Formula 1 does have a role to pay in promoting environmentally friendly technology for the road. While KERS technology is being implemented on a good few road cars already, the cars’ exhaust gases are certainly untapped in terms of power potential. I will note though that the cars themselves weren’t awful in terms of efficiency (the entire F1 grid, over an 18-race season, uses less fuel than a single Boeing 747 trip from London to Japan), it is a good improvement to make.

It is still unclear when these new rules and regulations will be fully released.
