The FIA may delay the introduce of four-cylinder 1.6-litre engines in F1, the World Motor Sport Council confirmed today.
A statement issued by the FIA said: In consultation with the main stakeholders, and following the outcome of this consultation, a fax vote by the WMSC could be considered by 30 June latest to redefine the implementation date of these technical regulations.
The WMSC confirmed the planned rules changes for 2013 included the new engines, with high pressure gasoline injection up to 500 bar with a maximum of 12,000 rpm, with extensive energy management and energy recovery systems (now known as ERS).
It also promised revised aerodynamic rules based on 2011 rules, with modifications in order to improve the aerodynamic efficiency: together with the power train rules, this will enable a 35% reduction in fuel consumption.
The heights of the cars noses will be altered for safety purposes and the number of transmission units teams may used will be further reduced to cut costs.
The minimum weight of the cars will be increased from 640kg to 660kg
