And just in case you haven't noticed yet, my "research" involves much more owner feedback then hard numbers. In other words, someone giving real world feedback about the good/bad points of a vehicle mean much more to me than 0-60 numbers published in an auto rag.
This might be OT but applies to times the Explorer achieved too. Since you seem to be so much more versed in automotive testing, do please share with us the testing methods MT used in the 2011 JGC road test, and also if it isn't too much trouble, please enlighten us as to the methods other various publications used in their tests (the publications you have privy to but we may have not seen...many of us did extensive research too). Just a technical FYI, a stopwatch is an "instrument" and using that with a human-controlled operator I would trust over, for example, an iPhone app or an affordable over-the-counter accelerometer (the kind automotive writers sometimes use).
Here are some means and methods used by car magazines:
* Some employ a "5th wheel" that performs a calculated digital measurement, otherwise known to the layman as a digital stopwatch tied to a digital speedometer and computer. Depending on calibration, this method may allow for one to two foot roll-outs before timing begins. (I actually did testing this way many years ago as part of my job)
* Some perform several tests after developing the best technique, throw out the best and worst times and average the remainder as a representative number. Some just publish the best run.
* Some load the drivetrain or dump the clutch (i.e. Car&Driver), some do not (i.e. Edmunds) and get significantly different results for the same vehicle. An average of runs is then posted as the "official" time.
* Some use an SAE dyno with corrective factoring to adjust raw times and report a time they never actually physically achieved on the road
. I know this is how some
powertrain engineers calculate factory estimates that get published and repeated (ad nauseam) by the press in their "road test" reports.
Which did MT use on that particular test?
How full or empty was the fuel tank?
What gasoline was in the fuel tank?
What mode (Auto, Sport, Snow)?
May I suggest you wait until you possibly buy a JGC in 2012 and do your own tests with your instrument of choice BEFORE refuting mine? My friend/neighbor, whom I do respect, had a good laugh at your remarks. I can't wait to see what you say if I run a 1/4 mile this summer at one of the NHRA tracks and report results that might be
better than what you read somewhere....can't wait.
