I got
39 miles /
63 km from a full charge to empty. Compare that to the official EPA range of 25 miles / 40 km.
Conditions:
- Dry roads, warm weather (mid to upper-70's / mid-20's C).
Settings:
- ECO drive mode (dulls/smooths out throttle response);
- EV mode (vs. 'EV Auto' mode, which may fire the gas engine sooner under higher loads);
- A/C off, windows open;
- Tire pressure at factory settings.
Driving techniques:
Basic eco-driving techniques -- this was no heroic hypermiling effort.
- 100% sub/urban driving; max posted limit of 60 km/h = 37 mph;
- Gradual acceleration (when not holding up following traffic);
- Looking well ahead to pick the lane with the best flow to minimize speed changes;
- Coasting to stops/turns as much as possible (when not holding up following traffic).
Note: I live in a sleepy little city with fairly laid-back drivers. I'd say about half the time I was accelerating/coasting, there was nobody close behind, so I could do my own thing.
With a bit more effort, I'm sure
70+ km / 44+ miles is doable in good conditions.
