Trip MPG exceeds MPH at freeway speeds

Recommended Posts

65mpg

This result - a personal best - was an unexpected surprise. Traffic was light and I was able to get from house to freeway (2 mi) and from freeway to work (also 2 mi) pretty quickly. Once on the freeway I put the ECC at 65 mph as always. During that stretch I bumped it up to 66 mph to move past a couple of semi trucks but for the most part it was right at 65. I noticed the outside air temp was 63F so I expected a loss of a couple mpg from the cooler weather.
So I was surprised to see 65.8 mpg for this trip which is 2 mpg higher than my previous best. The one stat that jumps out at me is that for this trip I was able to stay in EV mode for a full 15 miles which is 1 - 1.5 miles longer than normal.

 

I wish I knew why the higher result so I could reproduce it consistently.

The battery must have been fully charged, as I never get near this figure at freeway speeds. I am happy with a typical 43 MPG though, which is what I had hoped for when I bought the car. I do so little highway driving, except for vacation trips, that I am extremely happy with the city average.

Well unfortunately you can't always drive downhill ;)

 

Very impressive result I'm jealous.

One of the differences was that the car was used for a day trip yesterday and returned last night about 9 hours before my trip this morning. I wasn't the driver yesterday so I'm not exactly sure what paces it was put through but the HVB looked mostly (2/3) charged when I started the car this morning.
