McMurtry Automotive use Dymola along with the VeSyMA suite of libraries from Claytex/TECHNIA to aid in the development of their electric hypercars. At the 2022 Goodwood Festival of Speed the McMurtry Spéirling shattered the previous track record (set by a v10 powered Formula 1 car) by more than 2.5 seconds, with a 39.081 second lap! This groundbreaking vehicle has several technical innovations which are challenging to tune, and the tuning process substantially benefits from this flexible, multi-physics simulation platform. How Claytex/TECHNIA manage the VeSyMA suite of libraries will be presented, focusing on how these methodologies transfer to other simulation libraries/product development processes.
