The British supercar company has released a video that presents the McLaren XP8 and XP10 prototypes in their final testing stages.
The McLaren XP8 and XP10 prototypes are wrapped in black vinyl and represent the final step before the McLaren MP4-12C is 100 percent ready for the road.
This time the McLaren MP4-12C will be produced without help from Mercedes-Benz and even though we don’t have specific technical details yet, the video below mentions that the McLaren XP8 and XP10 prototypes are fitted with a revised M838T twin-turbo engine.
Watch the Video with the McLaren XP8 and XP10 Prototypes Testing after the jump.
