My recent experience is a trip from Montreal Canada to Boynton Beach Florida. Distance of 2770 km mostly on Interstates at an average of 130 km/hr. I had a full battery when I left and empty when arrived. No charging station in between. I had 16% ev driving on the meter. My fuel consumption was 8.4 liter/100 km or 28.4 mi/gal. Car was loaded near the top.

130 km/h ON AVERAGE? North to south through the US? That's quite impressive, isn't it? Managing 8.4 l/100 km on such average speed even more so. The speed would explain the very low EV% number though.

Andrev, it appears that you're stating your MPG in US gallons, as 8.4L/100km works out to 33.8 MP/Imp gallon.

Makes sense as he is in NA. All the more reason for all of us to stick to l/100km. No confusion there :D

For sure being in USA, the gallon was 3,78 liters. I use to do this trip for 18 years both ways, and it was the fastest I did. I had the Waze software on my screen showing police cars (not a lot) and traffic.
Pay attention, my average of 130 km/hr is when I was able to drive without obstructions, not the average speed for the entire trip. Construction cones and traffic jams are examples.
I was not alone going to that speed and plus!

Hi all,

Wanted to share efficiency (or lack thereof) during my initial trip in our brand new PHEV. I picked up the car in St. Louis, MO (elevation 550'/160m) and drove it 860mi/1400km to Denver, CO (elevation 5280'/1600m).

I began with a full charge and averaged 22mpg//10.7L/100km while averaging 77mph//125km/hr, half the time using cruise control.

I was pretty disappointed with the overall efficiency to the point where I'm wondering if there is something wrong with the vehicle. I expected to do MUCH better than that, although I acknowledge that I gained significant elevation along the way.

Is this reasonable? I was hoping for 35 mpg. Is there something I'm missing with the PHEV? Should I have been in one particular mode over another?

If 22-25 mpg is what I can expect on road trips cruising at 125 km/hr, I'm thinking I should have bought another diesel.

Thanks for the feedback.

You have 2 factors reducing MPG. First, the gas engine is new, not at peak performances. Second, you start at 500´ elevation and ended your trip at 5000´+. This is the major factor increasing the consumption. If you do the trip back, you will probably get your 30+ mpg.

Normally I would expect about 11 km/l on a long motorway trip. A heavy, not very well streamlined petrol car can never match a diesel motorway cruiser, not even close.

That seems to be quite high ... mind you it does depend a lot on your speed. I drive around the SE British Columbia and get around 8l/100km (opps, just noticed that you are using km per liter so we are close ... why oh why can't we all use the same damned system!). But, I was going to add that my speed is usually around 110km/h which is much less that the OPs 75Mile/hr.

Yes, I drive motorways @ 120/130 (Netherlands) and 140 average in Germany.
