I have a road trip of my own to report. I suppose I'll just hijack this thread.

Just got back from a trip from Orange County, CA (Irvine) to Cedar City, Utah. Each way we traveled 383 miles. From OC to CC I traveled at 75 MPH most of the way (cruise control) with AC on. I achieved 43.8 MPG. Roaming around the mountains out there after I filled up the tank once arrived, I traveled between CC and St. George (two trips @ 80 MPH Cruise Control w/AC) and some intense mountain hills (and some unexpected off roading at 10 MPH), about 430 miles or so I achieved 38.1 MPG uphill and 44 MPG down hill (according to the digital average) (with CC on set about 55). When I disabled cruise control and travelled same 55 MPH I then went up to about 53 MPH. I didn't keep good hand written records.

Going home today, on the next tank of gas (I filled up before leaving Cedar City), I traveled 85 MPG (Cruise Control) about 250 miles (and there were some spots where I was up to 95 MPH for about 15 miles going up some fairly steep inclines) but I mostly averaged ~75-85 MPH (had to, SUVs and big trailor trucks where nearly running me over even at 80) until little past Las Vegas and achieved 43.9 MPG. I got sleepy (we left at 4:00 am) so gave the car to my wife who never drove the Hybrid before (outside our paking lot where we live) and I fell asleep for two hours. Woke up, we were almost home and she had 74.9 MPG but she didn't use cruise control and the entire trip AC was on. Her speed was speed posted speed limit which was 75 most of the way until San Bernadino which was 65 but she did 70 in those areas.

Now, I drive exclusively with Cruise Control set since my 28 miles each way commute to work (and ~400 miles to Utah) and so on had no traffic, but she didn't use CC and otherwise our driving conditions were the same and got much better mileage. I'll do some tests the next two week not using CC at all and see what my mileage fares.

I realize the trip is downhill from Las Vegas to OC but so was the trip from Cedar City to Las Vegas.

I'll upload stats once I sort the gas receipts and my hand written odometer readings.


Thanks,
