Inside Line took the 2012 Chevrolet Camaro ZL1 and 2013 Ford Mustang Shelby GT500, together, on a field trip: to Westminster, California where where they were both tested on the same dyno at MD Automotive, run the by same operator on the same day. In case any memories need refreshing, the specs run thusly: the ZL1 has a 6.2-liter supercharged V8 belting out 580 horsepower at 6,000 rpm and 556 pound-feet of torque at 4,200 rpm, for a 0-60 time of 3.9 seconds and a top speed of 184 miles per hour. The Shelby GT500 rocks up with a supercharged 5.8-liter boasting 662 hp and 631 lb-ft, for a 0-60 time of 3.7 seconds and a top speed in excess of 200 mph. Both get the power down via six-speed manual transmissions. Funk Flex
