The LM uses essentially the same hybrid drivetrain as the GTR but with hardware changes that deliver more boost and hybrid power, guaranteeing the 1000hp (986bhp) combined output when running on everyday fuel. Gold-plated heat shielding (like the F1) features in the engine bay while the catalytic convertor pipes and exhaust headers are made from the ‘super-alloy’ Inconel, saving 4.5kg.
Where is the rest of the weight saved? A lot of it comes from ditching the race GTR’s air-jack system, plus the use of Lexan windows and titanium tailpipes and fixings. The seats save more weight: the LM gets those from the McLaren F1 GTR. Wheels and tyres are unique to the P1 LM but the Race Active Chassis Control is retained.
The GTR’s aerodynamics and styling are largely carried over but a modified rear wing and larger front splitter give a predicted increase in downforce of 40 per cent. This in a car that in GTR form was already said to generate 660kg of downforce at 150mph. You’ll spot the LM for its new rear wing but also its fully exposed carbon fibre roof.
Inside the air-conditioned cabin there are five-point seatbelts, orange Alcantara seat inserts, more carbon-fibre (even for the floor mats!) and a rather special steering wheel. It’s a modified version of that used in the championship-winning McLaren MP4/23 driven by Lewis Hamilton.
There are some other nice extras with the car, too. Such as engine diagnostics tablet computer, tailored car cover and battery charging system. Owners will also be treated to a 1:8 scale model of their car and framed picture.
After its demo runs at FoS the final set-up of the cars will be completed by Kenny Brack at the Nürburgring circuit.
Fastest road car at FoS this year? We shall soon know…
