The JD and VJ family is a series of 3.0-litre, naturally-aspirated V10 Formula One engines, designed by Cosworth in partnership with Ford; used between 1996 and 1999. [2] [3] The customer engines were used by Sauber, Stewart, Minardi, and Tyrrell. [4]
In order to produce a higher power at higher rpm, a completely new 2,992 cc (182.6 cu in) (89mm x 48.1mm) JD 72° V10 was designed for 1996, which produced about 670 bhp at 15,800 rpm, and used by Sauber Formula One team. This engine was further developed into VJ and VJM with the same V-angle, bore and stroke, reaching 720 bhp for racing, 730 bhp for qualifying, at 16,500 rpm. All three of these engines were badged as Ford Zetec-R as well, and used by several teams. In its debut season, the best result was another third place, this time taken by Johnny Herbert at Monaco. This was surpassed one year later by Rubens Barichello's sensational second place, again at Monaco, which was the first points finish for the newly formed Stewart Grand Prix team.

This article gives an outline of Formula One engines, also called Formula One power units since the hybrid era starting in 2014. 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.

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 @ 15,500 rpm in 1996, to over 900 horsepower, around 935 hp @ 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 @ 17,800 rpm, and 865 hp @ 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.

Second, the Tipo 205/B engine, introduced in 1964; with the 1.5 L engine configuration; and was designed by Franco Rocchi and Angelo Bellei. Then, a 42-year hiatus; until the FIA imposed a 2.4 L engine V8 configuration for all Formula One teams in 2006, with Ferrari introducing their Tipo 056; designed by Gilles Simon.
