F1 specifies 4-cylinder 1.6L engines from 2013; energy recovery systems, high-pressure injection and energy management
The FIA’s World Motor Sport Council (WMSC) has approved the introduction of a new specification engine for Formula One racing from 2013, underlining the FIA’s stated commitment to improving sustainability and addressing the needs of the automotive industry. Following dialogue with the engine manufacturers and experts in this field, the power units will be four cylinders, 1.6 liter with high pressure gasoline injection up to 500 bar (7,252 psi) with a maximum of 12,000 rpm.
Current units are 2.4L V8s, with a maximum of 18,000 rpm. The downsized engines will deliver a 35% reduction in fuel consumption and will feature extensive energy management and energy recovery systems, while maintaining current levels of performance. In 2013, five engines will be permitted per driver, but each year after that the limit will be four.
The WMSC also made several amendments to the 2012 Technical Regulations, including the inclusion of fuel compounds produced from biomass.
