Onroak was founded in 2012 by Jacques Nicolet who split the design, manufacturing, and sales divisions of his OAK Racing team into an independent company.

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.

[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.

[10] In 2015 Tork Engineering also built the tube framed racecar for the relaunched French Supertouring Championship.
