The Porsche 718 is a racing car built by Porsche between 1957 and 1962.
The 718 was a development of the successful Porsche 550A with improvements being made to the body work and suspension. The car is a RennSport build with a wheelbase shorter (German 'Kurz') than typical of predecessors of the era and this led to the car being referred to as the RSK. It had a mid-engined layout and used the 142 horsepower (106 kW) 1.5-litre Type 547/3 quad-cam engine introduced in the 550A. The car made its racing debut at the 1957 24 Hours of Le Mans driven by Umberto Maglioli and Edgar Barth. The car failed to finish the race due to an accident.
In 1958, the car finished first in class and third overall at Le Mans guided by Jean Behra and Hans Herrmann. Jean Behra also brought one of the cars home second at the Targa Florio. In 1959, the car, driven by Edgar Barth and Wolfgang Seidel, claimed overall victory at the Targa Florio. A 718 also won the European Hill Climb Championship in both 1958 and 1959.
In 1961 Masten Gregory and Bob Holbert piloted a 718/4 RS Spyder to a class win at Le Mans.
Initially a two-seater 1.5-litre sports car, the 718 was adapted to compete in a number of different formulas and also evolved due to regulation changes.
For the 1960 season the FIA made changes to the regulation regarding the windscreen and cockpit size. These rules changes together with a larger (1.6-litre) Type 547/3 engine, developing 160 horsepower (120 kW) and a new double wishbone rear suspension brought about the RS 60 model. The RS 60 brought Porsche victory at the 1960 12 Hours of Sebring with a car driven by Hans Herrmann and Olivier Gendebien. 1960 also saw Porsche win the Targa Florio with Hans Herrmann being joined on the winner podium by Jo Bonnier and Graham Hill. The RS 60 also ensured that Porsche successfully defended their European Hill Climb Championship for the third year in a row.
