A new video has been added on EVWORLD showing highway speed EV mode (up to 72 mph) in a PHEV converted Prius: EV WORLD TELEVISON: Cracking Toyota's 35 MPH Barrier
The fact the battery can be recharged while driving is pretty cool. I'm not sure I would want to use their 4th mode to do so but if it can be recharged like the stock battery can that would be something indeed!
The fact that the freeway speed is acomplished on the Gen II is old news, as open source hacks are already being used on some PHEV conversion businesses. What I can't WAIT to hear is when the 80hp EV motor on the Gen III is hacked. Now THAT will be worthy of a woo hoo! .
