Vector Sport has withdrawn their partnership with upcoming Hypercar debutants Isotta Fraschini due to a failure to release any data or input to the British outfit despite “repeated requests”.
The British team were set to partner with Isotta Fraschini for their FIA World Endurance Championship debut with a Le Mans Hypercar.
Vector Sport competed in the former LMP2 class during 2022 and 2023 in preparation for the 2024 partnership, which has not come to fruition. Isotta have instead partnered with Duqueine for their WEC debut.
Team Principal, Gary Holland, said: “The level of disappointment we feel about Isotta Fraschini’s stance is hard to put into words.
“We have been given minimal access and input into the development of this new Hypercar, despite solid earlier agreement about race car testing and development in preparation for 2024.
“We therefore have no real idea at all as to how the Isotta development has progressed.
“Vector Sport has registered for entry with the LMP2 in the European Le Mans Series for 2024 as was announced before the end of the WEC season, but we have no options in WEC at this late stage.
“We have, however, already entered into positive negotiations for 2025 and are looking forward to working with a manufacturer in WEC which aligns with our values and ambitions.”
Commercial Director Adam Shore added: “Our contract signed in December 2022 contains clear terms which have not been honoured by Isotta Fraschini.
“Their approach has been intransigent and ultimately a blatant breach.
“We have a range of legal options open to us of course, but we are a professional racing team aligned to the best interests of the sport.
“The FIA World Endurance Championship and those interests are paramount in our minds.
“As Gary says, we are more focussed for the time being on concluding arrangements for a competitive WEC campaign in 2025.”
The team will announce LMP2 plans for the European Le Mans Series in the coming weeks.
