When I bought my 03 Prius, I had to drive 818 miles back home. I broke up the trip into 2-3 hour segments driven at cruise control set speeds. This let me plot
MPG vs miles per hour. This will give you a lot of insight about how to get optimum performance. Be sure to factor in the wind speed and direction.
There have been some discussion of 'drafting' with various experiments and safety concerns. My personal point of view is following trucks often sacrifices the paint on the hoods and risks windshield cracks. But there are some savings in fuel economy. With a new car, I'd probably want to protect the paint and just enjoy the ride.
GOOD LUCK!
