Comments on: How to Hack a Prius and Enable its EV Mode http://www.realtechnews.com/posts/2616 Independent Tech News and Product Reviews from former VP and head of CNET.com and Longtime Computer Shopper Columnist, Alice Hill author of the popular "Hard Edge" column.

It comes standard with the EV button installed, and I've found without any doubt (via the fuel consumption history display) that judicious use of the EV button DOES save fuel - and it can be quite dramatic. Sydney has an undulating topography, with plenty of slow stop-start suburban streets. I'm getting the standard 5.2km/100Litres (as measured) down by starting from traffic lights on EV mode, and activating EV when going short distances from one red light to the next. On some trips this is a significant portion of driving. And, yes, you need to let it switch back into normal mode to recharge the batteries, but note that they also recharge quite nicely in braking mode (B on the selector) when going downhill or approaching next red light. You can improve on the standard configuration. I’ve owned a 2008 Aussi Prius for about 3 months now.

The energy gained from the generators would be less than the energy lost due to the extra drag (it'd take more energy to push the turbines through the air). Solar panels would be neat though. Easy to get damaged I'd guess, but I can't think of any other reason not to have them! “Wind generators” in the grille wouldn’t do any good.

This does _NOT_ improve fuel economy. The Prius computers are _very_ well programmed for efficiency, you will hurt fuel economy by using EV mode (As indicated in the Japanese owner's manual) 2. It will not hurt your car... unless abused. Basically, you don't want to put it into EV mode when the engine is warming up, either go to EV mode before the engine kicks on, or after it's warmed up completely. (Could harm catalytic converter) 3. It will not void your warrantly. No aftermarket parts will void your warrantly. Toyota may, if it can prove in court that this modification caused specific damange, deny warranty service for that particular damange. This has never happened for an EV mode mod. Yet. 4. It's great for reparking, and for sneaking up on people, showing of your silent car etc... but it's _not_ for everyday driving and will not improve fuel econimy.
