Is Formula 1 making a return back to 80s with ground effect cars and turbo engines? Seems likely as the teams are close to finalising all-new regulations for 2013. Autosport also reports that several Working Groups have been set up to get consensus on moves to both improve the spectacle of F1 and ensure the sport becomes more eco friendly.

For engines, draft regulations were circulated a few weeks ago and the latest suggestion is for a standard 1.6-litre four-cylinder turbo engine, aided by various energy recovery systems. They should produce around 650 bhp. Plans to limit engines to five per driver per season are being considered.

On the green front, teams are also keen for there to be a fuel flow rate limit – which will ensure the engines are economical. Williams technical director Sam Michael 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.”

To boost excitement, or in other words improve overtaking, ground effect is being considered. Williams boss Patrick Head and ex Ferrari designer Rory Byrne are working with FIA to draw the guidelines. “They are talking about putting a greater proportion of downforce to the diffuser, a ground effect car – like the early 1980’s. They have been looking at that, as well as increasing crash protection at the front of the car by moving the sidepods further forwards,” Michael said.
