The McLaren P1 LM Is Here And It’s A High Downforce Monster

We know that Lanzante have been busy converting a bunch of P1 GTRs into road legal machines but McLaren decided it was time for an official run of 5+1 P1 LMs. The first P1 XP1 LM has been built (seen in pics below) and it will be climbing up the Goodwood hill on Sunday. Lanzante will be building five more P1 LMs one of which will be dark grey like this and the other four in orange.

After Lanzante Motorsport won the 1995 24 Hours of Le Mans with their F1 GTR for McLaren, the company converted 5+1 cars back to road legal specifications, thus creating the F1 LMs. Production was limited at five units because McLaren wasn’t sure if they could sell more, but with the Sultan of Brunei buying three (two black, one orange), there wasn’t many left for the rest of the millionaires. Today, LM3 (orange) belongs to Ralph Lauren, LM2 (orange) is also somewhere in America while XP1 LM (also orange) remained at McLaren, forcing Lewis Hamilton to buy a 760hp Pagani Zonda with a manual instead. – Road&Track

Here are all the details of the P1 LM, straight from Lanzante:

Engine
The biggest change is to the engine hardware producing additional boost and hybrid power in order to maintain the McLaren P1 GTR’s 1000PS (986bhp). This is achieved while still using 99-octane fuel.

The engine bay features gold plated heat shielding while the catalytic convertor pipes and exhaust headers are made using the exotic ‘super-alloy’ Inconel saving 4.5 kg. Furthermore, the charge coolers will be produced with even more efficient cores to maintain power at higher run temperatures.

Chassis
Wheels and tyres are unique to the P1 LM but the Race Active Chassis Control and major parts of the McLaren P1TM GTR are retained.

The LM will be 60kg lighter than even the McLaren P1 GTR thanks to the removal of race parts such as the air-jack system, the use of lightweight seats from the McLaren F1 GTR, the Inconel exhaust and titanium tailpipes, lightweight fabricated charge coolers, Lexan windows, and the use of titanium bolts and fixings.

The final set up of the cars will be completed by Kenny Brack at the Nürburgring circuit.


Design
The advanced aerodynamics and styling of the McLaren P1 GTR are largely carried over to the P1 LM but with increased aero from a modified rear wing, and larger front splitter and dive planes. Together the changes give a predicted increase in downforce of 40%.

The P1 LM is uniquely fitted with a fully exposed carbon fibre roof and additional panels. Other exterior changes include orange brake callipers on the orange examples and silver on the grey ones.

Interior
Exposed carbon fibre covers the entire dashboard, instrument cowl, seat backs, roof, door cards, centre console and even the floor mats. Air conditioning is included as standard.

Orange Alcantara is used for the seat inserts and door pulls on the orange cars, black on the grey examples. Five point seat belts are also fitted.

The Alcantara trimmed steering wheel is unique to the P1 LM and is a modified version of that used in the championship winning McLaren MP4/23 driven by Lewis Hamilton.

Additional Equipment
The P1 LM will be supplied by Lanzante Ltd. with a full tool kit including a torque wrench and wheel socket plus diagnostics tablet. Included, too, will be a tailored car cover and battery charging system. Owners will also be treated to a 1:8 scale model of their car and framed rendering.
Did they say 986 horsepower on super premium gas, 40 percent more downforce and the seats from an F1 GTR?  I’m sold. The only problem is that I have a thing for prototypes, so if McLaren is keeping the P1 XP1 LM, I’ll need that other dark grey car.
