LIGIER JS P2
The closed LM P2 Ligier JS P2 sports prototype, which emerged from the Le Mans workshops at the beginning of 2014, was
conceived entirely in-house by the Onroak Automotive design department. Onroak Automotive was able to avail themselves of
the experience gathered with the Morgan LM P2 and the work carried out by the different teams running this LM P2. The team
made this new car with the ambition to achieve the same levels of performance and reliability as those of the Morgan LM P2 over
the past three years.
The Ligier JS P2 has been homologated for three years according to the current ACO-FIA regulations in force until 2017. Its sale
price agrees with the ACO-FIA cost-capped policy: €450,000 + VAT
The three engines currently on offer, the Honda HPD, the Judd HK and the Nissan VK45, can all be installed in the car’s engine
bay. Its closed monocoque will enhance the Ligier JS P2’s overall level of safety.
