In less than a week, the FIA could vote in a new engine for the 2013 Formula One season, and the smart money is on a turbocharged 1.6-liter four-cylinder to replace the current 2.4-liter V8s.

BBC Sport reports that the downsized engine is an attempt to mirror the mills used in road cars and increase consumer awareness of fuel conservation.

The FIA wants a 50% increase in fuel efficiency, a 10,000 RPM limit and will allow a combination of compound turbos and KERS to keep output somewhere between 600 and 750 horsepower.

Naturally, some teams, owners and principles are against the move, including both Ferrari and Mercedes-Benz. F1 boss Bernie Ecclestone seems to be one of the staunchest critics, saying "We have a very good engine formula. Why should we change it to something that is going to cost millions of pounds and that nobody wants and that could end up with one manufacturer getting a big advantage?"

The FIA is expected to vote on the measure this Friday.
