Filmed at Willow Springs International Raceway, this is truly a fight between brilliant home engineering and the best technology a legendary car company produces. Can a guy's first car actually hang with more than 50 years of performance evolution from Porsche? Can a good old honkin' American V-8 stick it to the slick, turbocharged Porsche mill? We find out in the best way possible, by running them head-to-head as hard as they will go with great drivers! #Porsche #Mustang #MotorTrend
