Many hours were spent in testing, particularly using long airport runways to simulate the mechanical and aerodynamic stresses induced on the long, fast Mulsanne Straight. In addition, Renault's engine department went to work on squeezing as much power out of the five-year-old powerplant as was possible.
A considerable amount of time was invested in testing, especially by utilizing long airstrips to simulate the mechanical and aerodynamic stresses imposed on the extended, high-speed Mulsanne Straight. Moreover, Renault's engine division aimed to optimize power output from the five-year-old engine.
