Lanzante Motorsport, the private race team that won the 1995 24 Hours of Le Mans, has been commissioned by McLaren Special Operations to officially convert five P1 GTRs into a new road-legal version of its hypercar that features a new high-downforce aero package.
In total the firm will build six cars: five 'production' P1 LMs plus 1 prototype.
The decision to grant Lanzante permission to convert the P1 GTRs to road-legal LM-spec was revealed by US magazine Road & Track.
Lanzante has already converted a small number of the 24 McLaren P1 GTRs for road use after it was approached by the track-only hypercar’s owners.
Featuring a modified rear wing, larger front splitter and anti-dive planes, the new LM version is claimed to come with as much as 40 per cent more downforce compared to the P1.
The LM also comes with a full carbon-fibre roof, new body panels and orange brake callipers.
Removing the GTR's air-jacks and the introduction of lightweight seats, a titanium exhaust, Lexan windows and titanium bolts and fixing has also cut 60kg from the kerb weight.
Air conditioning remains, while the steering wheel is said to be a version of the 2008 McLaren MP4/23 F1 car's wheel that was driven by Lewis Hamilton
Lazante says the GTR's more powerful 1000hp (736kW) twin-turbo 3.8-litre V8 petrol-electric hybrid engine carries over unchanged.
It's not known how much each McLaren P1 LM will cost.
Back in 1995 Lazante Motorsports converted 6 GTR race cars for road use and called them the F1 LM, one of which is still owned by McLaren.
