A virtual carryover from 2004, although XLE and Limited models got standard dual power front seats, supplanting a driver-only power seat.
2006 Toyota Sienna:
The Limited's front and curtain side airbags were made standard for all Siennas. Limiteds added power-fold door mirrors with integrated turn-signal lamps, plus a power-fold 3rd-row seat as an exclusive option.
2007 Toyota Sienna:
Toyota's minivan got more power for 2007. A 266-hp 3.5-liter V6 replaced a 215-hp 3.3 V6 as Sienna's sole engine.
2008 Toyota Sienna:
The 2008 Toyota Sienna was largely unchanged.
