Ferrari V10 engine

The Ferrari V10 engine was a series of 3.0 liter, naturally aspirated V10 racing engines that Ferrari built exclusively for its Formula One cars between 1996 and 2005. Ferrari chose ten cylinders as the best compromise between power and fuel efficiency, since the V12 offered more power but used more fuel and the V8 gave less power but greater economy. Over the decade of development output rose from 715 horsepower at 15,500 rpm in 1996 to roughly 935 horsepower at 19,000 rpm toward the end of the 2005 season. The Tipo 05 series, built from 2001 to 2005, was officially rated between 825 and 865 horsepower, and in qualifying trim these engines were reputed to reach or exceed 900 horsepower. Ferrari changed to a 2.4 liter naturally aspirated V8 for 2006.
