P1 GTR

The McLaren P1 GTR features enhanced hybrid powertrain producing 986 horsepower (735 kW) combined from twin-turbocharged 3.8-liter V8 generating 789 horsepower at 7,500 rpm with 20.58 psi boost plus 197 horsepower electric motor creating 738 lb-ft total torque at 4,000 rpm, achieving 0-60 mph under 2.8 seconds and 217 mph limited top speed with 50 kg weight reduction compared to road-going P1 creating 697 hp-per-tonne power-to-weight ratio. Track-only specification includes Formula 1-derived DRS drag reduction system, ERS push-to-pass functionality, and large fixed rear wing with race-oriented aerodynamic package.

Limited production of 58 examples available exclusively to existing P1 owners at $3.1 million pricing establishes ultimate P1 variant following completion of 375 road-legal examples, with subsequent Lanzante Motorsport conversion enabling handful of street-legal GTR specifications. The combination of hybrid powertrain technology, extreme aerodynamic development, and track-focused chassis calibration creates McLaren Ultimate Series pinnacle representing company motorsport heritage application in limited-production hypercar format, though track-only restriction limits ownership experience compared to road-legal P1 specification maintaining everyday usability alongside extreme performance capability.
