 | The new McLaren P1 GTR made its live debut on the floor of the 2015 Geneva Motor Show. |
| Based on the McLaren P1™ road car, the track-focused McLaren P1™ GTR design concept optimizes the aerodynamically efficient 'shrink-wrapped' body shape in order to offer maximum performance and superior handling characteristics. A host of changes have been made, and the car has been thoroughly re-engineered from the ground up. The P1’s drivetrain has been updated to deliver even more horsepower. Output now sits at 986hp, 83 more than the street-legal supercar. |
 | The additional power arises from the motorsport-optimized 3.8-liter, twin-turbo V8 along with a light-weight electric motor. Transmission is likely the P1’s seven-speed, twin-clutch automatic. |  |
