We put 3000 mi on the van since our purchase. Best highway mileage was 29 mpg using non ethanol, 91 octane fuel. 29 MPG fuel mileage conditions; tire pressure 35 PSI, 60 - 65 MPH, little wind, 50-60 degrees. Trip average 25 MPG. 87 octane kills mileage. The Touring increased weight and larger tires will not be as fuel efficient as our older 08 EXL with 16 inch tires. However, the cabin noise is noticeably reduced from the 08 making the purchase worthwhile & front suspension more substantial. The EXL/Touring w NAVI is a great travel vehicle for empty nesters or families.
Previously mentioned. I did find the Touring headlight auto on/off, 4 tire pressure monitor and multi-info display to be useful.
The new 2011 will simplify/reduce controls, hopefully further reduce noise and vibration over the last model, and improve mileage. Road Noise is not a factor on the 2010 Touring. Front suspension could be be more absorbent/progressive similar to the 2010 Ford Flex or Buick Enclave.
