707 horsepower, a Dallara tub, and a Triple Crown sentence: the McLaren MCL-HY is the 2027 WEC's first race-to-road document
McLaren pulled the cover off the MCL-HY on Monday afternoon UK time. A 2.9-litre twin-turbo V6 with the spec LMDh MGU pushes 520 kW (707 PS) to a rear axle anchored to a Dallara LMP2-base tub, 1,030 kg minimum. A road-going GTR sister sells through Project: Endurance without the hybrid, 730 PS, deliveries late 2027. Zak Brown framed the announcement around the Triple Crown of Monaco, Indy, and Le Mans. The car is a regulation document, a customer-programme proof, and a return to a class McLaren left in 1998. All three readings sit in the same chassis.
