Good find but alot of BS there though. 25mpg highway??? And 13.5 ¼mile and 4.9 sec 0-60 sound kind of generous.

CYD

Wheres the co-efficient of drag? Missing info!! Fail...hahahaha

j/k great post.

would of been a little easier if you spaced out the models more

Yeah, that list of numbers was generated by an individual who looked at the Factory Service Manual, but then went and added some more. The 13.5 is about the fastest that a stock car ever went in the 1/4, probably a zero reaction run. A more realistic number is 14.0.

Coefficient of drag is .29 for the 93 rx7. I believe the newer JDMs had .3249 or something like that.
