The FIA published a framework document yesterday, which has since been forwarded to teams and manufacturers in preparation for a final proposal due in September. Most of the changes are designed to affect both the chassis and powertrain designs and include such measures as introducing movable or active aerodynamic devices, and the adoption of four-cylinders displacing between 1.3 and 1.5L.
To keep things competitive, there would be no RPM or boost limits and drag would be lower than today’s racecars. Engines could feature turbocharging and energy recovery technology, however, the total amount of fuel consumed and the levels of carbon-dioxide emitted would be restricted.
The final major impact is the plan for lower costs by standardizing components such as wheels and brakes across all teams, homologation of components and assemblies and restrictions on crew numbers at races. This is definitely not the direction we want to see F1 heading to, so let's hope any changes introduced are nowhere near as extreme as these.
