McLaren P1 LM is the official road-legal version of the P1 GTR image

McLaren Special Operations was in charge of the 24 P1 GTR units that were built – but it appears some of the very wealthy buyers that got them also wanted a change to show them off on the streets.

This is because they were not too happy about the chance to only use their most prized possessions during McLaren organized private track days. This is when Lanzante comes in with its conversion for the 986-hp track machine into a road-legal ultimate hypercar. And it appears the firm even has official word from McLaren it can build five units of the new version – called P1 LM – essentially the P1 GTR in a form that allows the driver to take it anywhere. Aside from the five cars, there’s also a “P1 XP1 LM” prototype that will be on show at the Goodwood Festival of Speed on Sunday under the driver input of Kenny Bra?ck. Of course the P1 LM designation is a homage to the famed F1 LM from the 90s, a special edition that was also the work of Lanzante – back then Lanzante Motorsport wanted to celebrate its triumph at the Le Mans with an F1 GTR. Five cars plus a prototype were built back then – history repeats itself.

According to Road & Track, Lanzante told them all the juicy details. The P1 LM has the same 1,000 PS (986 hp) output as the P1 GTR due to the use of the updated version of the biturbo 3.8-liter V8 engine and a reworked hybrid setup. The engine bay uses gold-plated heat shielding and Inconel is being used for the catalytic convertor pipes and exhaust headers, which also brings a weight loss of 4.5 kilograms (10 pounds). There’s more to the diet – Lanzante claism the P1 LM will be 60 kg (132 lbs) lighter than the GTR due to the loss of some racing accessories. The design will largely be the same, save for a few aerodynamic improvements – reworked rear wing, beefier front splitter and dive planes. There’s also a fully-exposed carbon fiber roof and additional body panels will also come with the same treatment. Exposed carbon fiber will also be inside for the dashboard, headliner, center console, seat backs, floor mats, and the instrument cowl – and there’s even an air conditioning system.
