Until the mid-1980s Formula One engines were limited to around 12,000 rpm due to the traditional metal springs used to close the valves. The speed required to close the valves at a higher rpm called for ever stiffer springs, which increased the power required to drive the camshaft to open the valves, to the point where the loss nearly offset the power gain through the increase in rpm.
A modern-day Ferrari Formula One car being tested by Fernando Alonso at Jerez. The car is the Ferrari F10. In recent years, most Formula One teams have tried to emulate Ferrari's 'narrow waist' design, where the rear of the car is made as narrow and low as possible. This reduces drag and maximises the amount of air available to the rear wing.
The engine used in the Ferrari F333 SP sports prototype was a modified version of the 65-degree V12 engine used in the 1990 Ferrari 641 Formula One car, enlarged from 3.5 L to 4.0 L, for longevity, durability, and reliability, and producing 641 hp (650 PS; 478 kW) @ 11,000 rpm; detuned on power and revs from the original engine by about 40 hp ...
Lamborghini V12 L539. The Lamborghini V12 refers to the flagship V12 engine used by Lamborghini. Lamborghini has had two generations of V12 engines through their history, both of which were developed in-house. The first-generation Lamborghini V12 was a sixty degree (60°) V12 petrol engine designed by Lamborghini, [1][2] and was the first ...
Ferrari's first flat-12 engine design was the 1.5-liter Tipo 207, used in the 1964-65 Ferrari 1512 Formula One car (also known as the 512 F1). [6] The Tipo 207 flat-12 engine was designed by Mauro Forghieri and displaced 1,489.63 cc (90.903 cu in) with a bore and stroke of 56.0 mm × 50.4 mm (2.20 in × 1.98 in) and a compression ratio of 9.8:1 ...
1966 saw a 'Return to Power' as Formula One changed the engine rules once again, allowing engines of 3.0-litre normally aspirated, or 1.5-litre supercharged or forced induction. 1966 was a transitional year for most teams, however, the year did see the first use of composite materials, a technology which would later revolutionise the sport.
The engine displaced 1,489 cc (1.5 L; 90.9 cu in). This engine was installed in the Dino 156 F2 car and was first raced in the Grand Prix of Naples in April 1957, where it finished in third place behind two Lancia-Ferrari V8 Formula One cars. [5] [6] The result of the trio's creativity was the world's only 65° V6 engine.
The first Porsche flat-eight was the Type 753. Work began on it in 1960, following the announcement of a 1.5-litre displacement limit for the 1961 Formula One (F1) season. The design of the new F1 engine was done by Hans Hönick and Hans Mezger.
