Founded by Paul Lanzante, the British firm has retuned the stonking 3.8-litre twin-turbo V8 hybrid powertrain from the P1 GTR to run on 99-octane fuel, and then increased the boost to match the track car’s 986-horsepower (735kW) output.
Lanzante has also fitted new front and rear spoilers to increase downforce, a road-specification wheel and tyre package, Alcantara-trimmed cockpit, along with a new steering wheel inspired by the one used by Lewis Hamilton in his McLaren MP4-23 Formula One car.
Adding to the road-spec conversions, the British company also stripped nearly 60 kilograms from the GTR’s kerb weight - which was already 50kg lighter than the ‘standard’ P1 - by fitting a new exhaust system, tossing out the air-jack system and replacing the glass windows with plastic ones.
Other features of the P1 LM include gold-plated heat shielding (just like the McLaren F1) air-conditioning, orange Alcantara seat inserts and even more carbon-fibre - the roof is finished in fully-exposed carbon-fibre.
Buyers of the super-limited run of P1 LMs will also receive an engine diagnostics tablet computer, a tailored car cover, battery charging system, a mini-me 1:8 scale model of their car, and a framed picture.
Starting at 2.95 million pounds ($5.7 million) before taxes, the Lanzante McLaren P1 LM is not only hyper-expensive but also hyper-exclusive - limited to just six units, like its F1 LM ancestor.
