Got my 2013 last Saturday and filled up once. The computer said 36.5 but calculated 34.7. So far this tank the computer shows 38.6. Took a 200 mile roadtrip and the computer showed 40.5 for that 200 miles. Have not filled the second time yet. Car has about 600 miles on it.
I live in the country and have no city traffic to deal with.
Love this car!!!!!!!!!
