1. McLaren P1
The McLaren P1 is set to be the biggest debut of the year in 2013. Ready to succeed, but certainly not follow or replace, the F1, the P1 has extremely flowing, radical design, featuring a giant wing, bulging honeycomb taillights, and those signature McLaren tick eyes. Though the final design has yet to be released, the above picture is about as close to the real deal as a concept can get. Initial numbers were $1.56 million and 960 horsepower.
