INFINITI’s partnership with the Renault Sport Formula 1 team has proved instrumental in accelerating the VC-Turbo’s prototype testing in the latter stages of its development program.
As part of the natural development process for the engine, testing of earlier prototypes saw INFINITI addressing the challenge of component material development and durability.
One such instance revolved around the engine’s bearings. Thanks to its advanced multi-link system, the VC-Turbo engine features around three times as many bearings as a conventional internal combustion engine. VC-Turbo engineers identified a small bearing vibration which manifested at the highest engine speeds under certain conditions.
INFINITI’s VC-Turbo project engineers worked with the Renault Sport Formula 1 team to identify and isolate the vibration, using the team’s expertise in dynamic motion analysis in conditions of up to 20,000 rpm – far higher than any production engine. The team’s experience in movement behavior, and the use of bearing technology in a Formula 1 application, provided valuable insight into developing the engine. This stage of testing has confirmed the durability of the VC-Turbo engine under particularly challenging conditions.
