http://www.greencarcongress.com/2004..._camry_in.html sounds like a 2006 release thanks to the success of the HSD in all toyota hybrids.

i got around 20 km a liter when i drove a civic 5 spd using advanced hypermiler techniques
and now I drive a salvage nwh20 prius that gets almost to 25 km/l with 192,000 km to date.
