One of the classic metrics of a car is how fast it can go from 0 to 60 miles per hour (or 0 to 100 kph). E.g, the 2011 Bugatti Veyron Super Sport goes from 0 to 60 in an astonishing 2.4 seconds.
For an automatic, it seems like you could mash the accelerator to the floor and do 10 (or whatever) time trials and then average them. But is it possible you could arrive at 60 mph sooner by depressing the accelerator only a fraction of the way, or by pumping it?
And for stickshifts, isn’t the 0 to 60 speed in part due to the skill of the driver? Does the time trial take into account the correct shift points on the tranny, or is it just get to 60 in as short a time as possible, whatever the gear? What about the weight of the driver? The type and amount of fuel? The relative humidity, etc., etc.? It seems like a lot of variables could affect the outcome.
What’s the straight dope on how these measurements are made?
