It's a Blizzard Pearl IV (4) with Sunroof and Nav (major options)....and I was able to achieve 56.7 mpg on the way home. I'm leaving a Hybrid Highlander (sounds like a divorce) that in the end only was able to average 21 mpg. Although I'm looking forward to the improved FE, the tradeoff is space (3rd row seating), some level of comfort and sitting "above" the traffic. This coming week I have ~1800 miles that I will be driving so it will be interesting to gauge the ride/comfort following my return. Per the manual I need to vary my speed for the first 600 miles and avoid sudden stop or starts for the first 200 miles.....which could prove to be challenging since most of these miles are at highway speeds. Woo Hoo!
