The
Porsche 547/3 was used by
Porsche for
Formula One racing; between and In October 1958, the
Fédération Internationale de l'Automobile (FIA) announced that for the
1961 Formula One season, engine capacity would be limited to the same 1.5 litres as in
Formula Two (F2). This meant that Porsche could use their
Porsche 718-based central steering and open wheel F2 cars almost unchanged in future F1. The
Porsche 787 would not get the eight-cylinder though, continuing with the air-cooled,
DOHC four-cylinder Type 547
boxer engine that had been developed by
Ernst Fuhrmann and that had powered the 550 Spyders and
Porsche 718 series until then. It was powered by a 547/3 four-cylinder engine with Kugelfischer
fuel injection. At Monaco the car retired when the fuel injection cut out. A second car, also fitted with the 547/3 engine, was completed in time to appear in the
1961 Dutch Grand Prix on 22 May alongside the other 787. == Technical data ==
