McLaren is rumored to have big plans for the 2012 Paris Motor Show later this month. Word on the street is that is where the British automaker will unveil the long-anticipated successor to the legendary McLaren F1. Tentatively known until now as the P12, the new supercar could switch to the name P1 in homage to the original. According to a report from Inside McLaren, the Woking outfit is keen to build on the success of the MP4-12C.
