What is your best round trip M/KWh ?

What is your best round trip Miles/KWh so far ?
- Should be roundtrip to eliminate elevation changes
- Reset your m/kwh before you start the trip (or note it down after each trip so you can calculate for any trip)
- m/kwh should be from Leaf dash/console. NOT Carwings.
- Shouldn't be a trivial distance (like a couple of miles!)

My best is 5.8 m/kwh that I logged yesterday. The trip included over 1,000 ft of elevation changes - but I avoided the freeway.

How about a 50 mile minimum distance?

Depends on where you are and your driving patterns.

I hardly ever drive above 50 miles. I've done like 3 trips of above 50 miles in 4 months ;-)

I'm game, i'll start tracking it and posting averages and miles for big trips, days and maybe weeks. I agree, limiting it to long trips only a certain length nixes a lot of the driving us average folks do.

Roundtrip today-
103 miles
5.1 m/kw
5.7 miles below Very Low Battery warning
Approximately 83 miles freeway circa 55mph, 20 miles city streets circa 35mph. 1300' elevation difference between start and midpoint destination.

Well, I got 6.8 miles/kWh on a 73.8 mile round trip with an 1800-foot elevation gain yesterday, but I'm not sure if I believe the numbers! This was from South San Jose to Santa Cruz and back on highways 17 and 85. I kept my speed between 55-60 most of the way, dropping to 50 on the section of 17 where the speed limit is 50.

I reset at the top of the hill (1800 feet) and again at my destination before heading back. I got 3.1 miles/kWh on the way up the hill (22.1 miles), 18.2 on the way back down to sea level (14.8 miles), and 4.6 on the trip home (35.9 miles). This is all according to the center console. Combining the three segments, I get:

(22.1/73.8)*3.1+(14.8/73.8)*18.2+(35.9/73.8)*4.6 = 6.8 miles/kWh

The reason I don't believe it is because 6.8 miles/kWh should have netted me 143 miles of range (6.8 * 21 = 142.8), but I traveled 73.8 miles and only had 3 bars remaining when I got home, and I got one of those bars by trickle charging in Santa Cruz. What gives?

I've noticed the dash m/Kwh is always one to two less than the m/Kwh on the energy screen. So the highest M/Kwh I've obtained on a trip so far is 7.0 using the energy screen and 6.8 on the dash. That's all relatively flat city driving mostly around 38 Mph without any A/C and using CC.

That calculation is not correct.

total kwh = =22.1/3.1+14.8/18.2+35.9/4.6 = 15.7
total miles = 73.8
total mpkwh = 73.8/15.7 = 4.95

About 104 miles of range.

Thanks evnow. I was clearly trying to be too clever with my math there You can't do a weighted average of a list of m/kWh measurements.

Still, I'm impressed that the Leaf was able to get 4.95 on this route, especially considering that I get close to that on my regular commute which is much flatter. Regen does better than I expected!

I hit a new record on my commute today, thanks to heavier than usual traffic on the freeway. 56.7 miles, 5.8 miles/kWh (per the center console). The excitement of seeing the high number more than made up for sitting in slow traffic

I started with an 80% charge and made it home with 2 bars and 20 miles left.

Traffic was even worse today and I beat my own record with a 5.9. 75 minutes to go 27 miles (x2) is not that much fun though, even in the Leaf, so I'll be glad when my HOV stickers arrive. Playing the high efficiency game is fun though, so I'll probably only use the HOV lane to get past the tight spots.
