A vehicle is provided which may include an energy conversion device, an energy source to supply power to the energy conversion device, and at least one controller in communication with an interface. The controller may be programmed to output a distance to empty (DTE) to the interface based on conditions of vehicle components and the energy source compensated by a distance correction factor. The controller may further include a DTE prediction architecture including a feed-forward energy consumption estimator, an energy consumption learning filter, a distance compensator, and a DTE calculator. A method for estimating distance to empty for a vehicle is also provided which may output a DTE modified by a predicted DTE range loss selected to include a distance correction factor corresponding to and correcting for the noise factor.
