It strikes me as odd that the 1992 400E has the slowest times, yet it is the year with the most horsepower.

1992 had less stringent smog regulations, and allowed fuel enrichment at WOT (wide open throttle).

It is for this same reason that 1992 500E's are slightly more powerful than 1993 500E's / 1994 E500's.

Many of the guys on 500E.com are putting in chips from 1992 models in their 1993 and 1994 cars.
