Ferrari V10 engine
Ferrari manufactured a series of 3.0-litre, naturally-aspirated, V10 racing engines, exclusively for their Formula One race cars; between 1996 and 2005. They chose a V10 engine configuration, because it offered the best compromise between power and fuel efficiency; the V12 was powerful but thirsty while the V8 was weaker but economical. They switched to 2.4-litre naturally-aspirated V8 engine configuration for 2006. Over its decade-long evolution, power levels varied; from 715 hp (533 kW; 725 PS) @ 15,500 rpm in 1996, to over 900 horsepower, around 935 hp (697 kW; 948 PS) @ 19,000 rpm, toward the end of the 2005 season. The Tipo 05 series of engines, produced between 2001 and 2005, was officially stated to produce between 825 hp (615 kW; 836 PS) @ 17,800 rpm, and 865 hp (645 kW; 877 PS) @ 18,300 rpm. In qualifying mode, however, these engine were reputed to develop up to, or at times over, 900 horsepower (670 kW) at 19,000 rpm.
