2003 Prius plug-in?

The 2004-current, NHW20 model Prius has an EV mode option that puts the vehicle in electric vehicle (EV) mode. The 2001-2003, NHW11 lacks this built-in feature.

I have toyed with the idea but think a better approach is to look at an engine 'topping' cycle using a turbo-alternator to improve ICE efficiency.

Not from Toyota, of course, but there's a conversion kit from Coastal Electronics for anyone who really wants it.

The EV Mode OS firmware is accessible on US models. Several, including CoastaleTech.com and others offer installation kits:

Right, but as I said, that doesn't make it an option. When one says that a feature is an option on a vehicle, in common parlance that means you can buy a car with that feature for extra money.

I found a partial answer to my question at :

No, sorry, at this point we only convert Prius model year '04, '05 and '06. It's because the older generation Prius model uses a somewhat different technology than the '04 model, which doesn't lend itself to effective PHEV conversions.
