It was two adults and two children under 9. I was doing the posted speed limit ranging from 60-70 mph on average for highway and anywhere from 35-50 mph for city driving.
Thanks for your prompt reply!
I am in the market for a SUV and looking at the Tahoe, Yukon and the Hybrid seems very attractive due the the fact I drive a lot and I think I can save money in the long run besides doing our part for our Planet.
I know it might never happen but I would love to see a long wheel base Hybrid so I can take a lot with me during longer trips

..................may be a Hybrid Yukon XL or the Escalade ESV....!!??
Forgot to ask you: do you know if there is any difference in terms of interior space / trunk space on your Hybrid vs non-Hybrid Tahoe?
I just want to know do you have to sacrifice some room / storage space for the batteries.
