McLaren MCL-HY GTR: What is it?

Much like the Ferrari 499P Modificata, the McLaren MCL-HY GTR will be a track-only, limited-run iteration of the race car it is based on. Powering the MCL-HY will be a race-spec twin-turbocharged V6 mated to a hybrid MGU (Motor Generator Unit) system. This powertrain will drive the rear wheels, with a combined maximum output of up to 707hp. The MCL-HY features a lightweight carbon-fibre monocoque chassis.

As for the MCL-HY GTR, it will use a 2.9-litre twin-turbo six-cylinder engine with an estimated output of about 730hp. McLaren also claims that ditching the hybrid MGU system will result in a lower dry weight for the GTR variant while providing “a purer driving experience on track days and authentic hypercar performance and feel without additional complexity.”
