The entire complexion of the F1 business is set to change significantly from 2013.

Not only will there be a new concord agreement governing the commercial rights income distribution from such lucrative areas as television coverage contracts, trackside advertising and corporate hospitality, but also bold new technical rules, which will change the grand prix landscape for good.

As the teams head for Monza and this coming weekend’s Italian Grand Prix, a number of think tanks have been set up to consider various propositions. The latest concept is for a 1.6-litre four-cylinder turbocharged engine to become standard.

Couple this with ground effect aerodynamics, a fuel flow limitation and a possible limit of five engineers per season per driver and you’ve got a recipe for the most deep-rooted technical changes since turbocharged engines were introduced first time round in 1977.

How ironic that a technical development, which originally occurred by an accident of rule interpretation, should now be seen as the sport’s way forward.

Back in 1966, when the 3.0-litre F1 engine regulations were implemented, the FIA was concerned that there would be insufficient new power units to go round. So, as an interim measure, a provision was left in the regulations to allow 1.5-litre supercharged engines to be used.
