Even @ 75 miles per hour my XLE-V6 in 5th gear is just loafing along at about 1900 RPM. My TCH's FE starts tapering off about the time my XLE-V6 is just getting loosened up. At sub-highway speeds there is no contest the TCH wins by a landslide but on the road the gap narrows immensely and with the reserve power the XLE-V6 has makes XLE-V6 more of a pleasure to drive on highway trips with only a light FE penalty.

At 1900 RPM, my '95 V6 Camry is doing 55MPH. At 75 miles per hour, the RPM is over 2500. I will take a "test" ride in a '97 V6 and check the tachometer, but I would be amazed if the gearing is that much different between the model years. The cars have to weigh nearly the same. The '07 has a 3.5L vs. my 3.0L. But I will be amazed if the gearing is that much different. That alone would account for a big mileage difference.
