I wanted to see what I could get without using the heater tonight on my round trip.
Weather Condition: 30F and Windy
Cold Engine: 10.5 miles (42.7mpg), Normal mode, no heater usage, 60-70mph
Partially Warm Engine? (Left the car for 30 minutes): 10.5 miles (57.6mpg), Normal mode, no heater usage, 65-70mph
During the beginning of our crazy snow storm (we got 17.5-18 inches). Warm car, ~10 mile drive home on thruway @ 40-45mph, 50.2mpg with heat on auto-68* and rear defrost. I was quite impressed that even with the reduced traction, as long as the battery is warm the car will do near EPA numbers.
