A battery electric vehicle includes a speaker including an in-vehicle speaker that outputs a sound to the inside of the vehicle and an outside speaker that outputs sound to the outside of the vehicle. The battery electric vehicle further includes one or more processors configured to generate a pseudo engine sound and output the pseudo engine sound from a speaker mounted on the battery electric vehicle. When a vehicle speed of the battery electric vehicle is higher than a first speed, the one or more processors output the pseudo engine sound from the in-vehicle speaker, but not from the outside speaker. When the vehicle speed of the battery electric vehicle is equal to or lower than the first speed, the one or more processors output the pseudo engine sound from both the in-vehicle speaker and the outside speaker.
