1. A vehicle comprising:
- an electric machine configured to generate motive power for the vehicle;
a battery configured to store energy for the electric machine; and
one or more controllers configured todetermine a remaining energy of the battery,determine a series of energy consumption rates for the vehicle,determine whether at least one of the series of energy consumption rates differs from an average of the series of energy consumption rates by a predetermined amount, anddetermine an expected vehicle drive range (i) based on the remaining energy and the at least one of the series of energy consumption rates if the at least one of the series of energy consumption rates differs from the average of the series of energy consumption rates by the predetermined amount and (ii) based on the remaining energy and all of the series of energy consumption rates if the at least one of the series of energy consumption rates does not differ from the average of the series of energy consumption rates by the predetermined amount.

Abstract
A vehicle may include one or more controllers configured to determine a remaining energy of the vehicle'"'"'s battery, to determine a series of energy consumption rates of the vehicle, and to select a set of energy consumption rates from the series. The one or more controllers may be further configured to determine an expected drive range for the vehicle based on the remaining energy and the selected set of energy consumption rates.
