I have a new 06 Sienna CE (no options) The first 300 miles - mainly city and short trips 18.5 MPG My ODO is now at 548 miles and I just got back from a quick trip to Palm Springs, CA area:
110 miles ea way about 25 miles of shopping in town for a total of 245 miles - 9.792 gal or 24.99 MPG. My ave speed was 60mph with spurts to 85mph - got to watch that downhill speed. Temp was a "cool" 109 deg F. 115 had been anticipated- AC at full blast. On the road the manual AC seemed adequate. Short trips- the vehicle sits in a lot and then is driven only a few blocks - virtually no AC would be adequate in extreme temperatures such as this. Handling and directional stability at high speed and rough roads was excellent, power up and down hills to el 2800 hills - OK. Higher hills would benefit from a larger V8 . It did however hold its own in traffic without downshifting. I attempting to not abuse this new vehicle (much) during breakin period. The standard sound system is excellent with rear stereo speakers standard. Road noise is way less than my former ford van and Cad Seville which of course were both V8s and not V6 as the Sienna.
