I have a RaceLogic PerformanceBox which can be used to measure vehicle performance in a variety of tests. The Performancebox is a GPS based meter and data logger.
Unfortunately, I don’t get to use it all the time, so when I do there is a short period of re-familiarization. For my first tests, no data got written to the memory card. After I changed the setup to “yes, please write data” things improved dramatically.
Here was the best run written to the card today:
With 1 ft roll-out details:
Roll-out is a determination for ‘when’ the test time begins. At a drag strip, there is up to 1 foot of roll-out before the timing lights are tripped, hence the term. In other words, due to surface quality and wheel-spin it took me 0.59 sec to get 1 foot forward, but at the track that time would not have been included in the results and is not included above.
Weather Conditions: 87F; barometric pressure 29.69 in; humidity 64%. Fuel: Full
Not sparkling time for the Cadillac STS-V, which Cadillac measured at 4.9 sec 0-60 mph with roll-out. Most magazine tests ran high 4.x to low 5.x sec. Road & Track measured 4.7 sec 0-60 mph for the STS-V.
I feel the 2008 STS-V is capable of a better time. Getting the STS-V off the line involves a great threat of wheel-spin to be avoided. Of course, my test area is not a sticky well prepared launch spot like at the drag-strip, but it does closely model real world circumstances.
On the bright side, this is a new ‘best’ for my personal vehicle measurements; my previous best was 0-60 in 5.95 sec in my modified CTS 3.6L and was measured on the AP-22 meter in more favorable circumstances.

A line by line comparison — albeit of apples and oranges since different days, different gadgets — echoes the same issue — get the STS-V off the line faster and it would have much better times, and at 60 mph is 35 feet ahead of the CTS.
