I must be an idiot? I was reading Road and Track article with the Vette and Mustang GT500. The 0 to 60 times were faster than the rolling 5 to 60, why? Shouldn't it be the other way around? I looked up some other articles with different cars, and they are all the same. doesn't make sense to me.
Because 5-60 takes launch and traction issues out of the equation so it is a more pure indication of a car's torque and power. It is usually slower because wheelspin at launch can help keep revs up in a range where there is more power. Also AFAIK, it is Car & Driver that uses this test, not aware of anyone else adopting it.
I read an article somewhere (major car magazine) that stated that the S7 was actually faster than the 0-60 times would indicate. The reason is that the car redlines in 1st at 59MPH.
From a standing start, you are also launching harder, so your rate of acceleration is higher. Additionally many cars can easily break traction in first gear from a rolling start and it is much easier to control wheelspin and optimise acceleration using the clutch, rather than just rolling ob the throttle.
