The more environmentally-friendly units are expected to deliver a 35 percent reduction in fuel consumption, whilst providing the same level of performance enjoyed by today's F1 drivers. Energy recovery systems and additional energy management will be utilised to ensure this is possible.
“The WMSC approved the introduction of a new specification engine from 2013, underlining the FIA’s commitment to improving sustainability and addressing the needs of the automotive industry,” explained the FIA. “Following dialogue with the engine manufacturers and experts in this field, the power units will be four cylinders, 1.6 litre with high pressure gasoline injection up to 500 bar.”
Rev limits on the new engines will be reduced from the current 18,000 rpm to a maximum of 12,000 rpm.
An additional revision to the 2013 regulations will see a drop in the number of engines at drivers' disposal. Currently they can use eight units a season without penalty, but this will be limited to five in 2013 and reduced to four for subsequent seasons.
