Got this from Car-Stats.com.

 

What's interesting is there have been dips down as low as 2003 before. So you wonder if the trend is faster -> faster, or if the trend is instead slower -> faster -> slower -> faster.

Either way, pretty interesting stuff.

 

does that average include 1 of every vehicle made or does it take quantities of each vehicle made into consideration?

 

for example to my previous post, if say they had made 100,000 more 03 cobra's, that number would be ALOT lower (14.0 range i'd guess), but if its just 1 of each production car, then well you cant change it up much.

 

It's just one car per year. And it's not exact because it's based on magazine tests. The Lamborghini Diablo VT 6.0 is only listed for 2001, but I'm sure they made them for more than one year, and it counts just as much toward the avarage as the Toyota Camry does, though they sold a gazillion more Camrys.

 

Yes, that would make a difference, and explain why (in all reality, despite the jumps up and down on the graph) why the changes haven't been DRASTIC, but rather predictable over the course of 17 years.

 

1987 - 16.89's
2003 - 15.70's

Like it was said before, these are the good old days.

 

My two vehicles averaged together is 15.8. I'm average.

 

Actually, I'd be interested to see if the dips in performance (err, slower 1/4 mile times) actually coincide with new federal emissions regulations, crash test safety, etc. Then the cars slowly get faster, then new laws slow them down again, etc.
