The original EPA test involved:

1) many stops
2) average speed less than 30 mph in city
3) average highway speed ~48 mph

This is the driving profile of 40 years ago in rural, small towns not
served by interstates. These small towns had nearly universal speed
limits of 25 mph and at the city limits, two-lane, 55-60 mph roads. But
over time, population shifts, traffic management and road improvements
changed how we drive.

The hybrid drive excels at in the original scenario. The specific
savings are: (1) auto-stop when coming to a stop, and (2) automatic
switching between ICE and EV power. To achieve simular results, I
modified my commute route to maximize driving in simular to EPA profiles
and it has become easy to replicate the EPA results.

In some respect yes, in other respects no.  In summer I can meet the highway
figure for any trip longer than 30 miles by driving 55 mph (wind
not-with-standing) but on shorter trips I can't overcome the warm-up penalty
that quickly.  I can meet the city figure only after I get out of the
warm-up penalty box and, unfortunately, my commutes to town (3 miles at 55
mph) doesn't get me back on the ice.  In the winter, I can't meet either
figure, but I only lose about 10%.

What year or model?

Some of us are working on the problem for the 2001-2003 models:

Sorry about the poor English. Some was quoted from friends overseas and
I haven't take a lot of time to edit everything down due to other time
constraints.

Can't do much about spilled milk, so I would think a lot of future Prius
buyers will be pleasantly surprised how much more they get than the EPA
sticker. Unfortunately, buyers of traditional cars won't be so lucky.
Here in Agawam MA one can get a ticket for letting their car idle for 5
minutes or more.  I suppose something like this would be hard to enforce but
the gist of it brings to everyone's attention how wasteful it is to do
otherwise. I think the Prius is exempt from this ruling ;)
