2017 McLaren P1 LM Review – Introduced in 2016 after 375 systems were built, the P1 generated a race-only version named the McLaren P1 GTR. Developed at the demand of P1 owners who wanted a more severe variation of the supercar, the GTR got a more powerful hybrid drivetrain and production was limited to just 35 examples, all of which were made offered specifically to P1 owners. One certain rumor has been disturbing P1 owners and supercar enthusiasts alike since 2015, McLaren was secretly working on a street-legal GTR. It goes by the name McLaren P1 LM— as a homage to the iconic F1 LM and was conceived by Lanzante Limited, a British business that won the 1995 24 Hours of Le Mans with a McLaren F1 GTR through its Motorsport department and later became a service center for roadway and race-spec McLarens.
When we initially discussed the 2017 McLaren P1 LM back in April 2015, we hypothesized that the road-legal supercar will feature a few modifications compared to the GTR it is based upon. Our rendering artist removed the rivets from the cars nose and front lid, along with the race-spec tow hook and modified the canards on the front bumper. Last but not least, the supercar was painted Papaya Orange, the hallmark color of the F1 LM, while the carbon-fiber aero package of the GTR remained unaltered for a striking contrast.
The only things we missed out on are the customized rear wing, which sits taller than the GTR’s, and the larger front splitter and canards. These changes provide the LM a forecasted boost in downforce of 40 percent compared to the GTR, making it the most aerodynamic McLaren to date. The LM also comes with a completely exposed carbon-fiber roofing system and orange brake calipers on the orange examples and silver calipers on the remaining grey design.
The LM’s interior is as race-oriented as the GTR’s, however features a variety of extra information that set it apart from its track-only brother or sister. Highlights include Orange Alcantara insets for the seats and door pulls on the orange cars and trucks, and black on the grey example. Unlike the GTR, the LM has flooring mats. Other than that, it’s primarily similar to the GTR, featuring exposed carbon-fiber on the entire control panel, instrument cowl, seat backs, roof, door panels, and center console, basic a/c, and five-point safety belt.
Under the hood, the 2017 McLaren P1 LM includes the same hybrid drivetrain as the standard P1, but tuned to provide the same quantity of power as the GTR. The system brings together the twin-turbo, 3.8-liter, V-8 and a powerful electric motor, which sends out 986 horsepower, a 83-horsepower enhancement over the stock P1, to the wheels. The exact same race-spec, seven-speed, twin-clutch automated transmission is utilized, allowing the LM to hit 60 mph from a standing start in around 2.4 seconds, on its method to a leading speed of 217 mph. The engine bay includes gold plated heat shielding while the catalytic converter pipelines and exhaust headers are made utilizing the exotic ‘super-alloy’ Inconel, saving 10 pounds. Furthermore, the charge coolers were produced with much more efficient cores to maintain power at greater run temperature levels. The tires and wheels are special to the P1 LM, but the Race Active Chassis Control and major parts of the McLaren P1 GTR are kept.
Prices is clearly a secret at this moment, however the initial tweet that reported McLaren’s intent to build a road-legal GTR discussed it may be offered for ₤ 2 million ($ 3 million). This sticker label would make the LM the priciest P1 yet, as it would fetch a bit more than the GTR, which retails from ₤ 1.98 million ($ 2.94 million). We think that the LM will be sold for at least ₤ 2.5 million ($ 3.7 million) due to the five-unit production run, which makes it the most special P1 ever built.
