5-60 times are slower than 0-60 times because of how the test is performed...
0-60 involves rev-ing the engine way up and then just slipping your foot off the clutch (not the best for long-term reliability, but great for getting the best 0-60.
5-60 is a rolling start (like most owners would use). You are travelling 5mph with the clutch out and then you floor the gas.
Make sense?
