The engines came in both the original V10, and later V8 configurations, and engine displacement ranged from 2.4 L (150 cu in) to 3.5 L (210 cu in) over the years. Power figures varied; from 650 hp (480 kW) @ 12,500 rpm, to later over 900 hp (670 kW) @ 19,000 rpm. The 2.4-litre RS26 V8 engine, used in 2006, is one of the highest revving Formula One engines in history, at 20,500 rpm. Between 1998 and 2000, the RS9 engines were badged as Mecachrome, Supertec, and Playlife.
