MPG at certain speeds
I am wondering what mpg everyone is getting at a constant speed. Using cruise control, not touching brake or gas, level florida roads, 10 minute consumption data with steady results, 37psi in tires, and AC on I am getting at 75mph about 36-7 mpg. At 65mph 40mpg and at 55mph about 42-3 mpg. Is this what all the gsh's are getting?

I've noted that the average fuel economy displayed at fill up is a bit optimistic (about 4% higher than calculated at the pump). I have no good way of calibrating the 10 minute averages.
Still, it's pretty good fuel economy for a vehicle in this class.

I'll have to see what my car does when I get back in it this weekend. I think I do great around town. And experience a slight drop off at highway speeds. But overall I am happy to have performance and savings at the same time. Nothing like not having to think about gas until there is 500 miles on the trip odometer! Never came close to that when I had the 2010 GSh.

[QUOTE=moose66;8627567]Cold engine or not, I'd think you'd be getting higher MPG's in town. Isn't that what the hybrid system is supposed to take advantage of? Situations such as short trips where the speeds are low and the batteries can do the bulk of the heavy lifting. Plus you we have engine shutoff when completely stopped. All are all benefits to MPG's.
I find in town I get a lot more variability in the milage. A lot of my driving is at 35mph and if the battery is full then it runs on the battery Other times when the battery is either not full or not being used and starting from stop lights, the mpg is in the 20's mpg range . I suspect that the best milage at a steady speed will be around 50mph and will be over 45mpg!! Will have to find a road where I can try it out without blocking traffic.

My results so far exceed EPA estimates of 29/34/31. The European combined cycle, for the Euro-spec version of the GSh is 47.9 mpg. Adjusting for Imperial gallons, that would be the equivalent of 39.9 miles per US gallon.

I have a 2013 GSH with about 4200mi. I am consistently getting around 27-29 mpg. I drive a lot more aggressive than most. Even with my seemingly sorry mpg compared to everyone else, I am doing a lot better than my 2008 GSH, where I was getting 18-20mpg.
