McLaren's P1 has entered a tour across the United States to drum up more orders before it makes the final production step and the supercar was recently spotted at an exotic car dealership in Illinois.
Although the British carmaker has yet to release any specifications, but rumors indicate that the P1 will offer an output of over 800 hp and compete with the Ferrari Enzo successor and Porsche 918 Spyder.
The McLaren P1 will officially be unveiled at the 2013 Geneva Motor Show in March.
