When I was offered a chance to buy an early 2010 Prius and learned they only have variable angle valves, not variable duration, I almost walked away from the deal. Even now, our 1.5L, 03 Prius and the 1.8L, 10 Prius are getting 52 MPG. Of course the 1.8L has more space and does it 5 mph faster BUT I wanted 60 MPG. <sigh!>
