My Prius

A few days after my Prius arrived in Athens in October 2003
Chronicle
of My Prius
Early 2003. We first heard about the Toyota
Prius through our friend Jean. We rode in her 2002 Prius and were impressed by the hybrid concept, the fuel
economy, and its cool computer monitor (or “driver information system” as we
later learned).
We had considered the Honda Civic Hybrid earlier,
but a Toyota brochure that Jean handed to us converted us to favoring the Prius: a new generation of Prius
will be introduced in fall 2003 with a more powerful engine, better fuel
economy, and a hatchback version. We owned a station wagon and knew how handy
a hatchback could be.
We signed up for Toyota’s email list for
updates on the status of the new Prius. After
moving to Ohio, one day we received an email from Toyota indicating the 2004 Prius would arrive at the dealers in October 17, 2003.
October 18, 2003. We became the first
people to test-drive the only one Prius in Athens.
We were blown away when the engine shut off automatically upon stopping and
it was absolute silent. We wanted to buy it. Unfortunately the Athens dealer
said they’d keep it as a “program car” and would not sell it until 3 months
later, when we could go back and buy it at sticker price.
Figuring there would be more dealers (and
thus more Priuses/Prii)
available in the city, we drove up to Columbus and visited all 4 Toyota
dealers there. Still no luck. All of them had either sold their only Prius or would keep it for showing as the Athens dealer
did. Not until this point did we realize that each dealer was assigned only 1
Prius or 2, and that this car was in much higher
demand than we had expected. It seemed impossible to get one.
October 20, 2003. We test drove a Honda
Civic Hybrid in Athens. It is a solid car with great acceleration, but we
still loved the Prius better for its innovative
design and greater interior space, and, of course, the hatchback. The problem
is: how do you get one?
It came to us that we should probably try
dealers in neighboring towns. The reasoning went like this: Certainly there
would be more dealers in the city, however there would be more people
interested in the car too. The level of interest might not be that great in
smaller towns, as people in general prefer larger, more powerful vehicles.
This intuition proved correct. We started
calling Toyota dealers within a 60 miles radius from Athens. Parkersburg had
one but was sold out. Logan had one, so did Lancaster, but those two were not
the color/package we wanted. Finally, Chillicothe had one with the right
color and package. We drove there and again became the first people to test
drive it, and we drove it back to Athens.
December 2003. My Prius
made her first trip from Athens to Boston and back.
July 2004. My Prius
made her second trip from Athens to Boston and back.
August 2004. My Prius
made her third trip from Athens to Boston and back.
November 2004. My Prius
made her first trip from Athens to Chicago and back.

Why Prius?
People have said that the Prius (or hybrids in general) is not practical. In
particular, it is not powerful enough and it is too small.
I agree, if power and space are absolutely
critical to you.
Fortunately they are not to me. 99.9% of
the time I use the Prius for commuting on paved
roadways, for grocery shopping, and occasionally for showing it off to my
friends. For these purposes the Prius is as
competent as any vehicle.
Perhaps 0.01% of the time I would need a V8
engine or 4WD. But it simply does not make sense to drive a Hummer for that 0.01%
of my total use of vehicle.
Hybrids do not need my defense after all.
The Prius is in such high demand that the wait
period is 8-12 months now. Ford, based on the Toyota technology, has rolled
out a hybrid SUV, the Escape, in late 2004. GM is also planning to introduce
a hybrid truck in the near future. The market has spoken.

A winter visit to Champaign,
Illinois
2004 Prius in
Athens
Since I acquired my Prius,
the number of Priuses (or Prii?)
in Athens has grown tremendously. I would say Athens has one of the highest
concentration of Priuses in the country
I am happy to report that at least four
friends of mine decided to purchase a Prius after
seeing/driving mine!

Still in Champaign, Illinois. The
hatchback is one of the most useful features of this car.
Fuel Economy
Toyota claims the EPA estimate to be 60 (city)
and 51 (highway). The reason that the city mileage is higher is that at low
speed, the Prius system (as a manual calls it) can
rely solely on the electric motor without power from the gas engine.
Many have challenged the EPA estimates as
unrealistic. For example, Time magazine and U.S. News & World Report had
published test drive reviews obtaining estimates at around 48 mpg. However,
the discrepancy is understandable if we look into how the EPA estimates are
arrived. For example, the so-called “highway” estimate is actually obtained
by driving the vehicle on a treadmill at 48 mph for about 10 miles, which is
hardly your regular highway speed. If we the EPA estimate for Prius is too high, the EPA estimates for all vehicles are
all equally over-enthusiastic.
From my own experience, outside temperature
and driving habits are the most critical factors to fuel economy. The general
rules of thumb: (1) The lower the outside temperature, the worse the mpg.
This makes sense because in colder weather the gas engine needs to be on most
of the time in order to provide interior heat. (2) Aggressive acceleration
decreases the mpg. When the gas pedal is pressed hard, the gas engine would
kick in sooner. (3) The more often the Prius system
is turned on and off within a given period of time, the worse the mpg. The
gas engine simply needs time to warm up every time the system is turned out,
which inevitably decreases the mpg.
Having said these, it is definitely
possible to achieve the EPA fuel economy estimates with certain driving tips!
In a non-winter day I can normally get 52 mpg out of a trip from Athens to
Columbus (about 160 miles roundtrip) at 60-64 mph.
