context_page_description: Since its inception in 1947, Formula One has used a variety of engine regulations. "Formulae" limiting engine capacity had been used in Grand Prix racing on a regular basis since after World War I. The engine formulae are divided according to era.
context_section_description: This era used a 3.0 L formula, with a power range between 650 hp (485 kW) and 965 hp (720 kW). Renault was the initial dominant engine supplier from 1995 until 1997, winning the first three world championships with Williams and Benetton in this era. From 1998 to 2000 it was Mercedes power that ruled giving Mika Häkkinen two world championships. Ferrari gradually got better with their engine. For 1996, they changed from their traditional V12 engine to a smaller and lighter V10 engine. They preferred reliability to power, losing out to Mercedes in terms of outright power initially. At the 1998 Japanese GP, Ferrari's 047D engine spec was said to produce over 800 bhp (600 kW). From 2000 they were never short of power or reliability.
  BMW started supplying their engines to Williams from 2000. In the first season, the engine was very reliable though slightly short of power compared to Ferrari and Mercedes units. BMW went straight forward with its engine development. The P81, used during the 2001 season, was able to hit 17,810 rpm. Unfortunately reliability was a big issue with several blowups during the season.
  The BMW P82, the engine used by the BMW WilliamsF1 Team in 2002, had hit a peak speed of 19,050 revolutions a minute in its final evolutionary stage. It was also the first engine in the 3.0 litre V10-era to break through the 19,000 rpm-wall, during the 2002 Italian Grand Prix's qualifying. BMW's P83 engine used in 2003 season managed an impressive 19,200 rpm and cleared the 900 bhp (670 kW) mark and weighs less than 200 lb (91 kg). Honda's RA003E V10 also cleared the 900 bhp (670 kW) mark at the 2003 Canadian Grand Prix.
  In 2005, the 3.0 L V10 engine was permitted no more than 5 valves per cylinder. Also, the FIA introduced new regulations limiting each car to one engine per two Grand Prix weekends, putting the emphasis on increased reliability. In spite of this, power outputs continued to rise. Mercedes engines had about 930 bhp (690 kW) in this season. Renault, Toyota and Ferrari had about 900 bhp (670 kW). BMW had about 950 bhp (710 kW). Honda had about 965 bhp (720 kW).
