It's called EV mode:
Not long ago we did a piece on how hybrids while great did not actually
save you money - mostly because of their cost compared to a basic Honda
Civic. But the Prius has become more than just a way to save money, for
many techies and celebrities, it’s “the” cool car because it’s
small and understated and high tech. Yeah, yeah. But to those who own a
hybrid, here’s way to hack it so it works mostly in battery (EV) mode,
thus boosting your mileage even further. Did you Know: In the US this EV
mode is disabled where it ships standard in Europe and Asia. Wonder why …

Every Toyota Prius that rolls off of the assembly line has the programming
built into the computer to enable “EV” (”electric vehicle”) Mode.
EV Mode tells the computer controlling the Prius to turn off the gas
engine and use only its batteries until one of the following things
happens:
* the batteries get too discharged (down to 2 bars on the Prius’ Energy
display)
* the vehicle speed hits 35mph
* the driver asks for a lot of power (climbing a steep hill or getting onto
the highway)
* the drive disengages EV Mode

Yep, I know about this. I also understand that one cannot really do the
hack here in the USA because it will void the warranty. Bummer that.

In practice (I live in the UK and own one) the EV mode is hardly worth
having. Because of all the (correctly stated) reasons that override it, it
only really works at cold start and allows a silent pull away from your
drive by preventing the gas engine from doing its usual start up to rapid
warm the catalytic converter. It can also give you a silent slow speed
arrival late at night! Under all other circumstances it gets overridden by
the Prius engine and battery management systems as necessary. I (and many
others over here) believe that the EV mode switch is activated in Europe
because it makes it a true "alternative fuel" vehicle (by using the battery
exclusively, even if only momentarily) and therefore qualifying it for
various tax concessions.

One thing I would like to see here would be some manner of switch or
rheostat that would allow a bit more dependence upon the electric than it is
set up for now. I never run the battery low and could use that electric
power moreso than I do.

Actually you never have any real choice about how much (or little) you use
stored battery energy. The EV mode makes very little difference to this.
It would probably be bad news if you could! Just an early death for the
battery................... It's frustrating to think that there might be a
deal of stored energy that you don't get to use but I reckon it's better to
let the Prius look after itself and just drive it.
