I am.

18 mile commute to work, 36 miles round trip. Mix of both highway, and city streets.

Averaging between 45 to 47 mpg the past week of driving it everyday. I'm not exactly light on the pedal either. Loving this van!

I'd take pics, but the trip message indicating mpg turns off too fast, or I just forget.

Are you following the trip computer or calculating after you fill up? I got around 39 on my first long highway trip (calculating from fill-up - trip computer had me a little lower). I certainly haven't see anything like 45 to 47 though. Regardless, pretty amazing MPGs for a vehicle this size.

IMO, 45-47 mpg in good weather and with conservative driving is not impossible to attain. However, wait until you visit the gas station, because the trip computer can be inaccurate. For example mine usually is too "optimistic", almost always showing 5 to 10% better mpg's than the real figures.

It may be interesting to visit Fuelly to see what mpg's other drivers are reporting.

it depends on the level of charge on the battery and how you brake and accelerate. I also drive a Prius C , got around 55 -60 MPG city driving.
lowest is like 40 MPG and highest is like 70 MPG in a short 10 miles drive.
if you can capture as much energy as possible when your brake, you will get higher MPG. that is what I know after drive hybrid for 10 years.

Agree... Lots of coasting and cruise control, and if you can avoid the "power" white part of the hybrid tachometer like it's the plague, that also really helps.

I've been trying to explain this to my wife for months now. Brake very early, even if only gently. We're not wearing down the friction brakes. We're charging the battery. Exactly right.
People who do not have a spirited driver in the family might wonder how you can go from 45 mpg to 25 mpg on a quiet country road at 20 mph in fine weather .... that's how :)

The 13 minutes was the whole drive, including the 6 minutes of the first leg, which was immediately after the car had sat for about 1.5 hours as we were 🚲 🚲 ng. Looking at the MPGs the engine was warm enough.

Between the first and the second, 7-minute leg of the car sat for only about 15 minutes. I didn't look at the temperature Gauge but I don't think it will have dropped a lot.

I'll stick with the passionate driver theory ☺

I use the cruise control as much as I can even around town. When I start out within out community I press the set button and it automatically comes to 20 mph. One on the road, I gradually accelerate to the local speed limit and press set. When I have to stop at a stop sign or light, I press resume to come back up to speed letting it decide how to accelerate. I also use the dynamic cruise control in traffic so that it matches the speed of the vehicle ahead and maintains distance. I believe it does a better job of getting good mpg than I can do. It certainly does not come close to peeling rubber or slamming on the brakes. In watching the mpg indicator, it seems to like 50 to 60 mph on cruise control indicating 40 to 50 mpg. At lower speeds the indicated mpg is about equal to the mph. My overall average is 37+ and improving with mostly local driving.

YES, I've been getting 39 MPG highway and also 47/48 in the city on a regular basis. It's incredible for such a big car! Unfortunately, we had our first frost here in Indianapolis yesterday morning. At that time, I was only able to get 24mpg on the same morning drive to drop kids off at school and to work. We park outside too so it takes a minute to warm up. I imagine that's going to start becoming the new average.
It also plummets dramatically when towing a trailer. I was barely getting 20 pulling a [email protected] teardrop 700 miles. I was even getting as low as 18 on several stretches through the mountains. It sounds really bad but then I think about the SUVs around me who are getting 18 on a good day without towing anything. That made me feel better.

Here is the mpg trend vs. ambient temperature .... the winter is finally catching up with us, which is immediately reflected in lower fuel efficiency.

Computer shows 33.9 overall, so it's pretty close. City driving, I get much better. This includes quite a bit of highway as well, but only at ~65 max. Probably close to 50/50 mix.

Just completed a 700 mile trip from southern Missouri to Orange Beach. Temps was 31 to low 40's for about first 1/3 of trip then to low 60's, however we were bucking a moderate head wind 3/4 of the way. Speed 40 to 50 in hilly Arkansas and 60 to 68 on interstate and state roads, managed 38.5 mpg on arrival. Hauled a lot of extra crap for our snowbird thing.

Same route, similar speeds, in summer we have gotten 42ish on several different trips on same route, so it is very repeatable for us. Wind, temps weight made a 4 mpg difference for the worse.
