Ligier Automotive

Onroak's roots can be traced to December 2009 when OAK Racing reached an agreement with Pescarolo Sport to take over their manufacturing arm, specifically the continued construction and co-development of the Pescarolo 01 Le Mans Prototype that had been designed in 2007. OAK, while under their previous title of Saulnier Racing, had been a Pescarolo customer since 2008, campaigning two cars in the European Le Mans Series.^[3] OAK eventually became the sole developer of the 01 design when Pescarolo went into receivership, and campaigned and sold the cars under the OAK-Pescarolo moniker.

In 2012 new regulations for Le Mans Prototypes required teams to replace existing cars with new designs or alter them to meet the regulations. Onroak was created to develop a new design for the existing Pescarolo chassis as well as to pursue sales of the car to other teams seeking cars meeting the new regulations.^[1] Onroak then formed a partnership with Morgan Motor Company to brand the LMP2 class variant of their new design as the Morgan LMP2,^[4] while the LMP1 version retained the OAK-Pescarolo title.

During 2013 Onroak formed a partnership with Guy Ligier to assist in the development and sales of an evolutionary version of the Ligier JS 53 Group CN prototype before designing a closed-cockpit variant known as the JS 55 in 2014.^[5][6] This agreement extended to naming rights for a new LMP2 car designed and constructed entirely by Onroak in early 2014, the Ligier JS P2.^[5] Onroak and Ligier followed the JS P2 with the JS P3 intended for the LMP3 class which debuted in 2015.^[7]

In October 2016, Onroak bought the motorsports arm of American manufacturer Crawford Composites.^{[citation needed]}

Onroak was selected as one of the four LMP2 manufacturers for the 2017 regulations. The Ligier JS P217 has competed in the LMP2 class in European Le Mans Series, IMSA SportsCar Championship and the FIA World Endurance Championship. Its chassis was also used by the Nissan Onroak DPi which competed in the DPi class of the IMSA sportscar championship.^[8]
